Document the policy and post it in a conspicuous place so that it is known to all your employees. Furthermore, disseminate the policy to all potential sources of employees and to your subcontractors asking their cooperation. The policy statement should recognize and accept your responsibility to provide equal employment opportunity in all your employment practices. In regard to dissemination of this policy, this can be done, for example, through the use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web page postings, employee handbooks, and advertising. EQUAL EMPLOYMENT OPPORTUNITY OFFICER Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of administering and promoting your company's Equal Employment Opportunity program. This person should have a position in your organization which emphasizes the importance of the program. 3. INSTRUCT STAFF Your staff should be aware of and be required to abide by your Equal Employment Opportunity program. All employees authorized to hire, supervise, promote, or discharge employees or are involved in such actions should be trained and required to comply with your policy and the current equal employment opportunity laws. 4. RECRUITMENT (a) Let potential employees know you are an equal opportunity employer. This can be done by identifying yourself on all recruitment advertising as "an equal opportunity employer". (b) Use recruitment sources that are likely to yield diverse applicant pools. Word-of-mouth recruitment will only perpetuate the current composition of your workforce. Send recruitment sources a letter annually which reaffirms your commitment to equal employment opportunity and requests their asistance in helping you reach diverse applicant pools. (c) Analyze and review your company's recruitment procedures. -to 1'i entify7lnd eliminate discriminatory barriers. cp) (d) Select and train persons involved in the employment process -_to 6% o ective standards and to support equal employment opportunity goals. t t (e) Review periodically job descriptions to make sure they accurately reftett mStob functions. Review education and experience requirements to make sure they accurately reflect the requirements for successful job performance. ' (f) Review the job application to insure that only job related questions are asked. Ask yourself "Is this information necessary to judge an applicant's ability to perform the job applied for?" Only use job-related tests which do not adversely affect any particular group of people. (g) Monitor interviews carefully. Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws. Biased and subjective judgments in personal interviews can be a major source of West Riverbank Stabilization Project 0520 — Page 4 of 6 discrimination. (h) Improve hiring and selection procedures and use non -biased promotion, transfer and training policies to increase and/or improve the diversity of your workforce representation. Companies must make sure procedures for selecting candidates for promotion, transfer and training are based upon a fair assessment of an employee's ability and work record. Furthermore, all companies should post and otherwise publicize all job promotional opportunities and encourage all qualified employees to bid on them.

Terracon's geotechnical scope of work included the advancement of three test borings to approximate depths of 36.5 to 47 feet below existing site grades, as well as sediment sampling in the Iowa River at seven locations. Information from other explorations performed along the alignment were also used to supplement this exploration. Based on the information obtained from our subsurface exploration, the site is suitable for development of the proposed project. The following geotechnical considerations were identified: ■ Significant depths (i.e. 7 to 13 feet) of uncontrolled existing fill were encountered along the trail alignment in the borings. Uncontrolled fill is not considered reliable for the support of structure foundations. Complete removal and replacement of the fill is not anticipated to be economical for this project. Structures such as the proposed bridge and retaining walls should therefore be supported on driven pile foundations. ■ If the box culvert alternative to the bridge is chosen at the creek crossing, a shallow mat foundation supported on native materials may be feasible. However, to adequately dewater the bearing soils during construction, a cofferdam and well points will likely be required. ■ The risk of poor trail pavement performance due to uncontrolled fill can be reduced with the, recommended partial overexcavation and geotextile placement; however ther*signer and City should understand that the risk cannot be eliminated without complexly rerlOving the fill. '� <3 ■ Portions of the existing fill materials could potentially be used as site g fill; however, significant sorting to remove unsuitable materials, as well as moisture corallti inTbf the soils would be required. v, o ■ Based on the limited subsurface information obtained during our site exploratiocgthe 2012 International Building Code (IBC), seismic site classification for the proposed bridge or culvert site is C. ■ Earthwork on the project should be observed and evaluated by Terracon. The evaluation of earthwork should include observation and testing of engineered fill, subgrade preparation, foundation bearing materials, and other geotechnical conditions exposed during construction. ■ Only preliminary design information was available for the preparation of this report, therefore as the design advances additional recommendations will likely be required. Terracon should be provided plans at the schematic stage to determine if additional recommendations are Responsive ■ Resourceful ■ Reliable Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 1 rerracon required, and at the pre-bid stage to confirm that our recommendations have been properly implemented. ■ Our recommendations did not include design and construction of USACE approved flood protection structures. Additional field exploration, laboratory testing, and analyses would be required if the project will include flood protection. This summary should be used in conjunction with the entire report for design purposes.

The purpose of these services is to provide information and preliminary geotechnical engineering recommendations relative to: ■ subsurface soil and rock conditions ■ excavation considerations ■ site preparation and earthwork ■ lateral earth pressures ■ seismic site classification per IBC ■ groundwater conditions ■ dewatering considerations ■ foundation design and construction ■ pavement design and construction ■ frost considerations The subsurface exploration scope of work for this project included the advancement -9f three test borings to depths ranging from approximately 36.5 to 47 feet below existing site grade Sa i9nt samples were also obtained at seven locations from the Iowa River channel bottom. c A Site Location Plan (Exhibit A-1), a Boring Location Plan (Exhibit A-2), a subsu4,ac6%il profile (Exhibit A-4) and logs of the borings (Exhibits A5 to A-7) are included in Appendix A of this repo I- The results of the laboratory testing performed on soil samples obtained from the site4pring the field exploration are included on the boring logs and/or in Appendix B of this report. Deacriptions of the field exploration and laboratory testing are included in their respective appendices. Terracon performed a prior subsurface exploration for a proposed pedestrian bridge (Terracon Project No. 06955103, Geotechnical Engineering Report dated October 19, 1995). The information from this prior exploration was also used in developing the preliminary recommendations contained in this report. The boring log from that exploration is also included in this report as Exhibit A-8. A planned fourth boring was not performed at the request of the client, McLaughlin Whitewater Design Group (MWDG), since the City of Iowa City (City) provided us with logs of borings performed by Team Services (TEAM Report No. 1-3398, dated October 9, 2013) on the 21 Benton Responsive ■ Resourceful ■ Reliable 1 Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lrerracon Street property, which included borings on the proposed alignment. Borings 2, 3, and 3A from this report are included as Exhibits A-9 to A-11. The following are not included in this preliminary geotechnical engineering report: ■ Stability analyses of the proposed retaining walls are not included in our scope of services. We can provide these analyses, once the preliminary wall designs are completed. It should be noted that our field exploration was not intended to develop recommendations for a USACE certified flood protection system; if such a system is planned, additional exploration and testing would likely be required. ■ Flashboard gates and scour protection recommendations are not included in our scope of service, and we understand that the required analyses will be performed by MW DG. 2.0 PROJECT INFORMATION 2.1 Project Description The client has provided us with the Iowa River Corridor Trail — From Benton Street to Sturois F r Par preliminary plan set dated October 27, 1997 by Shive-Hattery, Inc.

Approximately the northern one-third of the proposed trail alignment is mapped as "Karst and Potential Karst" by the Iowa Department of Natural Resources (IDNR). However, mapping by the IDNR shows no sinkhole activity within 1 mile of the site. Further exploration, including rock coring and/or geophysical survey methods would be required to better evaluate the bedrock for Karst. However, we are not aware of any Karst related foundation/structure distress in the vicinity.

Borings by Team on the 21 Benton Street property to the west of the alignment encountered bedrock at depths ranging from about 74.5 to 76 feet. Conditions encountered at each boring location are indicated on the individual boring logs. Stratification boundaries on the boring logs represent the approximate location of changes in native soil and rock types; in situ, the transition between materials may be gradual. Details for each of the borings can be found on the boring logs in Appendix A of this report. The subsurface conditions encountered in our exploration were generally similar to those found during our September 1995 exploration. Responsive ■ Resourceful ■ Reliable 4 Preliminary Geotechnical Engineering Report 1(�rracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Sediments from the Iowa River bottom were fine to coarse and medium to coarse sands with trace gravel. The sand samples farthest downstream (S-1 and S-2) were "silty" and "with silt', respectively, while the remaining samples had trace silt. All the sediments were poorly graded. Plots of the particle size distribution are provided on Exhibits B-2 and B-3. 3.3 Groundwater Conditions The borings were observed for the presence of groundwater during drilling and sampling. The mud -rotary procedure introduces drilling fluid into the boreholes, making water level observations shortly after the completion of drilling (e.g. same day) unrepresentative. After completion of our drilling operation, the boreholes were backfilled with on-site soils. Water levels observations are presented in the table below.

C;' These water level observations provide an approximate indication of the groundwatef cond8ai ns existing on the site at the time the observations were made. Longer-term observations using cased holes or piezometers, sealed from the influence of surface water, would be rouired for a better evaluation of the groundwater conditions along the alignment. Fluctuations of the groundwater levels will likely occur due to seasonal variations in the Iowa River stage, amount of rainfall, runoff, and other factors not evident at the time the borings were performed. Therefore, groundwater levels during construction or at other times in the life of the structure may be different than the levels indicated on the boring logs. The possibility of groundwater level fluctuations and perched water should be considered when developing the design and construction plans for the project. Responsive ■ Resourceful ■ Reliable Preliminary Geotechnical Engineering Report l�erraeon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION 4.1 Geotechnical Considerations Based on the results of the subsurface explorations, laboratory testing, and our analyses, it is our opinion that the proposed bridge and retaining walls should be supported on deep foundations such as driven piles that extend to competent bedrock. If the box culvert alternative is chosen, a grade supported mat foundation appears feasible. Primary geotechnical considerations include: ■ Existing variable fill; ■ Bedrock variability; ■ Shallow groundwater; ■ Rubble zones and cobbles and boulders. Further details are provided herein. 4.1.1 Existing Uncontrolled Fill Existing fill was encountered in the borings to depths ranging from about 7 to 13 feet below existing grades. Based on the SPT results (N -values ranging from 1 to 16 blows per foot) and highly variable composition of the fill, it appears that the fill was not placed as engineered fill with consistent control of moisture and density. Records regarding fill placement were notfrovided to Terracon for the preparation of this report, and likely do not exist. As such, the existingfill should not be considered reliable for support of foundations, and risk of possible poor perforgiance for trail pavements must be accepted if portions of the existing fill are allowed to remain it place as a cost saving measure. a% Support of pavements on or above existing fill soils is discussed in this report. However, eveh with the recommended construction testing services, there is an inherent risk.for the --City that highly compressible fill or unsuitable material within or buried by the fill will not be discovered. This risk of unforeseen conditions cannot be eliminated without completely removing the existing fill, but can be reduced by performing additional testing and evaluation. We anticipate that complete removal of the fill will not be economical for this project. Therefore, as a minimum to reduce some of the risk of abrupt differential settlement, we recommend at least 18 inches of granular fill be placed below pavements. A high -tensile geogrid could also be placed below the crushed limestone base course to further reduce the risk of abrupt differential settlement. 4.1.2 Soil Improvement Systems As an alternative to supporting retaining walls on deep foundations, they could be supported on existing fill materials that have been improved with methods such as "Geopier® Rammed Responsive ■ Resourceful ■ Reliable 6 Preliminary Geotechnical Engineering Report ��rra�on Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Aggregate Piers", "Vibro-Replacement Stone Columns , or other similar aggregate pier systems that extend through the fill soils to suitable native soils. These soil improvement methods are proprietary systems designed by licensed contractors who could provide further information regarding these support options. Typically, foundations supported on aggregate pier improved soils can be designed with net allowable bearing pressures ranging from 3,000 to 6,000 psf. The design bearing pressure is provided by the aggregate pier designer/installer. 4.1.3 Bedrock Variability The depth to bedrock varied along the alignment from about 36 feet to a depth of more than 70 feet estimated based on our familiarity with bedrock conditions in the vicinity. Deep foundation lengths will vary along the alignment due to the varying depths to bedrock and degree of bedrock weathering. Additional borings and/or geophysical methods could be used to better evaluate bedrock depths along the alignment. Wherever deep foundations are planned, we recommend that the bid documents include an add/deduct line item to account for bedrock variations. 4.1.4 Shallow Groundwater Dewatering should be anticipated for deep excavations that extend to near or below Iowa River stage. Quick conditions will result in sandy soils if excavations extend below the water table and proper dewatering measures are not performed. If the box culvert alternative is chosen, we anticipate that a coffer dam and well points will be required for construction dewatering. N 4.1.5 Rubble Zones and Cobbles and Boulders - Zones of both rubble/debris in fill sections and cobbles and boulders in native sand and gravel strata were encountered in the borings. These could act as obstructions during ,deep 'foundation installation, requiring pre -drilling through fill sections, and/or requiring offset acid/or additional replacement piles. S . a 4.2 Site Preparation and Earthwork 4.2.1 Site Grading Pavements, topsoil, vegetation, uncontrolled fill consisting of rubble or debris, and any otherwise unsuitable materials should be removed from the construction areas. Excessively wet or dry material should either be removed or moisture conditioned and recompacted. Soft and/or low- density soil should be removed or compacted in place prior to placing new fill. After rough grade has been established (e.g. the planned overexcavation for minimum recommended 18 -inch crushed stone section), the exposed subgrade should be proofrolled by the contractor and test probed by Terracon. Proofrolling of sandy soils could be accomplished using a vibratory drum roller (gross weight of 10 tons or more), while clay subgrades could be accomplished using heavy, rubber -tired construction equipment or a tandem axle dump truck (gross weight of 20 to 25 tons). This surficial proofroll would help to provide a stable base for the Responsive ■ Resourceful ■ Reliable 7 Preliminary Geotechnical Engineering Report l��rracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 compaction of new structural fill, and delineates low density, soft, or disturbed areas that may exist below subgrade level. Unstable materials that cannot be satisfactorily improved by scarification and recompation should be removed and replaced with new structural fill. Subgrade conditions should be observed by Terracon during construction. Dewatering during construction could be required; design and deployment of dewatering measures are the responsibility of the contractor. We expect that sump pits and pumps would generally be adequate for dewatering excavations above the water table where perched water is present. More extensive dewatering measures, such as sheeting and well points will be required for excavations extending below the water table, which is anticipated to be at to slightly above Iowa River stage. The groundwater level should be maintained at least 2 feet below the lowest excavation level. Upon completion of filling and grading, care should be taken to maintain the subgrade moisture content prior to construction of pavements. Construction traffic over the completed subgrade should be avoided to the extent practical. Where practical, grading should be performed to prevent ponding of surface water on the prepared subgrades or in excavations. If the subgrade should become frozen, desiccated, saturated, or disturbed, the affected material should be removed or these materials should be scarified, moisture conditioned, and recompacted prior to pavement construction. r, C3 v 4.2.2 Soil Stabilization As previously discussed, the existing fill soils are anticipated to vary in composition- consistency/relative density, and strength. The City should budget for additional costs toprovlde the required corrective measures. If left in place, corrective measures will probably be required) to increase subgrade stability during subgrade preparation. If the existing fill soils are left in-placo a layer of crushed limestone at least 18 inches thick should be placed below new pavem Tents as previously discussed; however, a greater thickness could be required in some areas. A geetextile stabilization material could also be placed below the crushed stone to help stabilize the subgrade soils. To improve stability and create a stable base for compaction of new fill, we recommend the exposed soils be scarified, moisture conditioned and recompacted as discussed above. 4.2.3 Excavation Considerations All excavations should comply with the requirements of OSHA 29CFR, Part 1926, Subpart P, "Excavations" and its appendices, as well as other applicable codes. This document states that the excavation safety is the responsibility of the contractor. Reference to this OSHA requirement should be included in the project specifications. Slope heights, slope inclinations and/or excavation depths should in no case exceed those specified in local, state or federal safety regulations, including current OSHA excavation and trench safety standards. If any excavations extend to a depth greater than 20 feet (e.g. box culvert), side slopes and/or bracing must be designed by a professional engineer according to OSHA regulations. Responsive ■ Resourceful ■ Reliable 8 Preliminary Geotechnical Engineering Report lferracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Where granular soils are encountered, excavations will likely require shoring or bracing to maintain stability. The bracing or sheet piles should be designed to resist the lateral earth pressures and any adjacent surcharges while maintaining tolerable deformations, and would reduce the potential for caving or sloughing of these cohesionless soils. Sloped excavations could be considered if the lateral extent would not impact adjacent utilities, pavements or structures. Where poorly compacted variable fill materials are encountered, flatter slopes than those required by OSHA could be required to maintain the stability of the excavation(s). The information provided in this report is intended for its use by our client for this project only. Under no circumstances should the information provided below be interpreted to mean that Terracon is assuming responsibility for construction site safety or the contractor's activities; such responsibility is not being implied and should not be inferred. Construction site safety is the sole responsibility of the contractor, who shall also be solely responsible for the means, methods, and sequencing of construction operations. 4.2.4 Fill Material Requirements Fill placed in structure and pavement areas should be low plasticity cohesive soil or granular soil. Fill placed in confined excavations, utility trenches crossing pavements and structure foundation overexcavations should consist of relatively clean and well -graded granular material. This should provide for greater ease of placement and compaction in confined areas where larger compaction equipment cannot be operated. The use of granular fill in these isolated and potenti6y deeper excavations would reduce the potential for differential settlement. The native sand soils encountered in the borings are considered suitable for aise_aasc ite rriss grading fill. The clay soils from the fill sections could possibly be reused; howev,2r, sjgnifical�i sorting will be required where zones of highly variable composition, organic materials, n2nlbblej other deleterious material are encountered in the existing fill.

Structural fill should consist of approved materials that are free of organic matter and debris. Frozen material should not be used, and fill should not be placed on a frozen subgrade. A sample of each material type should be submitted to the geotechnical engineer for evaluation prior to use on this site. 2. Low plasticity cohesive soil would have a liquid limit less than 45 and a plasticity index of less than 23. 3. Fill materials used for proposed site grading should have less than 5 percent organic content. Appropriate laboratory tests, including Atterberg Limits for cohesive soils, organic content tests for dark colored soils and/or those that exhibit a noticeable odor, and standard Proctor (ASTM D698) moisture -density relationship tests should be performed on proposed fill materials prior to their use as structural fill. Further evaluation of any on-site soils or off-site fill materials should be performed by Terracon prior to their use in compacted fill sections. 4.2.5 Compaction Requirements Item Maximum Fill Lift Thickness Minimum Compaction Requirements1,2 1 Moisture Content Range' Description ■ 9 inches or less in loose thickness when heavy, self-propelled compaction equipment igased ■ 4 inches in loose thickness when hand -guided equipment (i.e. jumping jack or plate compactor) is used ■ 98% beneath foundations and within" foot of finished pavement subgrade ■ 95% above foundations and more than 1 foot below pavement subgrade ■ Low plasticity cohesive: -2% to +3% ■ Granular: -3% to +3%4 1. As determined by the standard Proctor test (ASTM D698). 2. If the granular material is a coarse sand or gravel, or of a uniform size, or has a low fines content, compaction comparison to relative density may be more appropriate. In this case, granular materials should be compacted to at least 70% relative density (ASTM D 4253-00 and D 4254-00). 3. Moisture levels should be maintained at levels satisfactory for compaction to be achieved without the granular fill material bulking during placement or pumping when proofrolled. 4.2.6 Grading and Drainage Final surrounding grades should be sloped to provide effective drainage away from the top of retaining walls and pavements during and after construction. Grades around retaining walls and Responsive ■ Resourceful ■ Reliable 10 Preliminary Geotechnical Engineering Report �err�cora Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 pavements should also be periodically inspected and adjusted as necessary, as part of the structure's maintenance program. Water permitted to pond next to the retaining walls or on pavements can result in greater soil movements than those discussed in this report. These greater movements can result in unacceptable differential wall and pavement movements. Estimated movements described in this report are based on effective drainage for the life of the walls and pavements and cannot be relied upon if effective drainage is not maintained. 4.3 Deep Foundation Recommendations Heavily loaded and/or settlement intolerant structures, such as the proposed bridge and retaining walls should be supported on driven pile foundations. Augercast piles were considered; however, due to the relatively shallow depth to bedrock over portions of the alignment as well loose sands being present, only a relatively low capacity would be developed. Drilled shafts could also be considered; however, construction through the existing fill materials and water bearing sand soils would require a combination of casing and slurry drilling. We can provide design and construction recommendations for augercast piles and shafts upon request. 4.4 Driven Pile Foundations Steel H -piles or pipe piles driven to practical refusal in the limestone bedrock could be used for support of the bridge and retaining wall structures. Driven piles will derive their compressive loan capacities from end bearing in the underlying bedrock. In our opinion, where piles w4 be driven near existing structures or other improvements, H -piles should be used instead .of pipe pilgs, 4) reduce lateral movement and heave of the soils. u r� Preliminary allowable design compressive load capacities of driven steel piles could b64alculated by taking the allowable steel working stress of 15 kips per square inch (ksi) for piles driven to refusal times the cross-sectional steel area. However, we recommend that the steel have a f m,, of at least four (4) times the working stress (e.g. a pile designed for 15 ksi should have a fy m,,, of 60 ksi) to reduce the potential for damage to the piles during driving. For example, an HP 10x42 pile could be used for this project and an allowable design load of about 185 kips could be used for piles driven to practical refusal in the underlying limestone bedrock. Typical rock penetration for driven piles will vary based on pile size and location across the building area, but is estimated to small. Individual pile settlement should be on the order of /cinch when designed according to the criteria presented in this report. Differential settlement between individual piles can typically be estimated at'/2 to % the total settlement.

An allowable passive resistance of 6 kips is recommended for driven steel H -piles, if a detailed lateral load analysis is not performed. Preliminary input values for LPILE are provided below. We can provide input parameters for other analysis programs and/or perform the LPILE analysis upon request. Recommended input values for use in LPILE analyses that represent the materials encountered in the borings are shown on the table below. LPILE will estimate values of k h and E50 based on strength; however, non -default values of kh should be used where provided. Since deflection or a service limit criterion will most likely control lateral capacity design, no safety/resistance factor is included with these parameters. Our recommendations are based on Boring B-103 being the controlling case for maximum lateral deflection; LPILE input parameters can be provided for other borings upon request. We recommend setting the water table at the 100 -year flood elevation in analyses.

Responsive ■ Resourceful ■ Reliable 12 Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lierracon Group action for lateral resistance of piles should be taken into account when spacing is less than six (6) diameters (center to center), and design parameters for allowable passive resistance in the direction of the load should be reduced in accordance with the following table. We can provided guidance for p -y multipliers if detailed analyses using LPILE are planned. Pile/Shaft Spacing (Diameters) I Reduction Factors 6D 1.0 4D 0.85 The piles should be spaced the greater of at least three pile flange widths or web heights (for H - piles) or diameters (for pipe piles) apart (center -to -center) if they will be used to resist lateral loads. Pile caps and/or grade beams could be subject to uplift loading due to frost action; thus, perimeter foundation elements beneath unheated areas should extend at least 4 feet below the lowest adjacent finished grade for frost protection. It should be noted that the load capacities provided herein are based on the stresses induced in the supporting soil and rock strata. The structural capacity of the piles should be checked to assure that they can safely accommodate the combined stresses induced by axial and lateral -forces. Lateral deflections of piles should be evaluated using an appropriate analysis method, and will depend upon the pile's diameter, length, configuration, stiffness and 'fixed head" or "Free head" conditiIn. We can provide additional analyses and estimates of lateral deflections for specs ieloadinRi conditions upon request. The load -carrying capacity of piles may be increased by increasing the) section (for H -piles), diameter (for pipe piles) and/or length. w 4.4.2 Construction Considerations — Driven Piles The contractor should select a driving hammer and cushion combination which is capable of installing the selected piling without overstressing the pile material. The hammer should have a rated energy in foot-pounds at least equal to 15 percent of the design compressive load capacity in pounds. The contractor should submit the pile driving plan and the pile hammer -cushion combination to the engineer for evaluation of the driving stresses in advance of pile installation. During driving, a maximum of 10 blows per inch is recommended to reduce the potential of damage to the driving system. if practical refusal is experienced above the anticipated rock surface elevation, then the pile may be on a boulder or other obstruction and a replacement pile should be driven. K this occurs, the situation should be evaluated by Terracon during the pile driving operations. Difficult driving could also be encountered in the weathered rock. Consideration should be given to using protective points and/or flange stiffening if H -piles are used. The contractor should be prepared to cut or splice piles, as necessary. Splicing of piles should be in accordance with specifications provided by the project structural engineer.

A Terracon representative should observe pile driving operations. Each pile should be observed and checked for buckling, crimping and alignment in addition to recording penetration resistance, depth of embedment, and general pile driving operations. The existing adjacent structures and subsurface utilities should be observed prior to pile installation to document their condition. These structures should also be observed during pile installation for any indications of movement. Pile driving should be stopped and Terracon contacted if movement or cracking of the existing structures is observed. Monitoring vibration levels during pile driving should be considered. It should be understood that although vibrations from pile driving may be below levels that will cause structural damage, they may be felt by occupants of the adjacent buildings. The potential impact of driving piles at this site should be considered when evaluating this alternative. Terracon is able to perform vibration monitoring upon request. 4.5 Box Culvert Foundations If a box culvert is used instead of a bridge for the unnamed tributary to the Iowa River crossing, we anticipate that it would be a reinforced concrete box (RCB) culvert with a bottom elevation) near 635 feet. 4.5.1 Box Culvert Design Recommendations DESCRIPTION VALUE Foundation type ■ Rigid reinforced mat foundation Bearing material ■ Minimum 12 inches of well -graded crushed stone over medium dense native sand or loose native sand compacted to a medium dense condition Net allowable contact pressure ■ 2,000 psf Total estimated settlement' ■ 1 inch or less Estimated differential settlement ■ % of total settlement 1. Actual net contact pressure is expected to be lower than 2,uuu psr. 2.

We anticipate that a cofferdam and diversion of flow through the unnamed tributary will be needed to construct the culvert. Groundwater levels should be maintained at least 2 feet below the proposed excavation grades to reduce disturbance of the bearing soils. This will likely require the use of well points to lower the water table within the cofferdam. It should be noted that "quick" conditions will result in sandy soils if excavations extend below the water table and proper dewatering measures are not performed. This would significantly reduce the bearing capacity of the subgrade soils and may result in subsequent settlement of the culvert and overlying trail pavement. The specifications should include a performance requirement for the construction dewatering system. Construction and backfilling of the box culvert should be conducted well in advance of the trail pavement construction. This will allow expected settlement to occur without causing premature pavement distress. For an asphaltic cement concrete pavement section, consideration could be given to placing the base course and then the surface course at a later date. Where lower strength soils and/or loose sands cannot be densified in place and/or if unsuitable bearing soils are encountered along the culvert foundation excavation, the excavation should be extended deeper to suitable soils and the culvert should bear on properly compacted structural backfill extending down to the suitable soils. Overexcavation for compacted-6ackfill placement below the culvert should extend laterally beyond its edges at least 8 inches per foot of overexcavation depth. The overexcavation should then be backfilled up to the cul igrt's base elevation with well -graded granular material placed in lifts of 6 inches or less in loose thickness and compacted to at least 98 percent of the material's maximum Standard Proctor dry density (ASTM D698).

The current scope does not include a 100 foot soil profile determination. Borings extended to a maximum depth of 62 feet, and this seismic site class definition considers that moderately weathered bedrock continues below the maximum depth of the subsurface exploration. Additional exploration to deeper depths, or seismic velodty testing would be required to confirm the conditions below the current depth of 4.7 Lateral Earth Pressures Reinforced concrete walls with unbalanced backfill levels on opposite sides, such as retaining walls, should be designed for earth pressures at least equal to those indicated in thid following table. Earth pressures will be influenced by structural design of the walls, cQnditiolts of wall restraint, methods of construction and/or compaction and the strength of the materials being restrained. Two Wall restraint conditions are shown. Active earth pressure is comm(iOy used for design of free-standing cantilever retaining walls and assumes wall movement. The "at -rest" condition assumes no wall rotation and should be used where the wall's geometry restrains them from movement. The surcharge components would apply where drives, surface parking or other loading will be applied adjacent to the below grade walls. The recommended design lateral earth pressures are for cast -in-place concrete walls only, do not include a factor of safety, and do not include any provision for possible hydrostatic pressure on the walls. These recommendations are not applicable to the design of modular block - geogrid reinforced backfill walls, and additional analyses and evaluation would be required for these walls.

Backfill placed against structures should consist of granular soils or low plasticity cohesive soils. For the granular values to be valid, the granular backfill must extend out and up from the base of the wall at an angle of at least 45 and 60 degrees from vertical for the active and passive cases, respectively. Heavy construction equipment should not operate within a distance closer than the exposed height of retaining walls to prevent lateral pressures greater than those provided. Backfill placed in non-structural areas adjacent to the walls should be placed in thin lifts and compacted using hand -operated equipment to at least 95 percent, but no more than 100 percent, of the material's maximum standard Proctor dry density (ASTM D 698). Wall drainage and the potential for hydrostatic pressure should be carefully considered in preparing final plans for the retaining walls constructed within the flood plain of the Iowa River. Walls incorporated with flood protection should be designed for hydrostatic pressures. Walls not associated with flood protection should have effective drainage such that rises and falls of the river stage will be mirrored in the backfill zone. Filtration will be an important consideration to reduce losses from the backfill zone through weep -holes or other wall perforations due to fluctuations in water levels. Terracon should be retained to provide further consultation once wall profiles and design intents are determined. Combined hydrostatic and lateral earth pressures for lean Gay backfill can be calculated using an equivalent fluid weighing 90 and 100 pd for active and at -rest conditions, respectively. For granular backfill, an equivalent fluid weighing 85 and 90 pcf should be used foractive and at -rest, respectively. These pressures do not include the influence of surcharge, equipment or pavement loading. 4.8 Trail Design and Construction Recommendations _a Traffic volumes and loading conditions were not provided. We understand the proposgd trail will primarily be used by pedestrians and bicyclists; however, maintenance vehicles su`l) as small (i.e. gross weight under 20 tons) single -axle dump trucks could occasionally use the trail. 4.8.1 Trail Subgrade Preparation As previously discussed, existing fill from about 7 to 13 feet deep is anticipated along most of the trail alignment, therefore complete removal of the existing fill is not expected to be economically feasible. Therefore, as a minimum, we recommend placing at least 1 foot of properly compacted granular fill below the recommended 6 -inch thick crushed limestone aggregate base. The upper Responsive ■ Resourceful ■ Reliable 18 Preliminary Geotechnical Engineering Report r�rracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 1 foot of subgrade material should be placed on stable portions of the existing fill, and should be compacted to at least 98 percent of the material's maximum dry density as determined by ASTM D698. In addition, we recommend the aggregate base consist of a dense -graded crushed stone meeting IDOT Section No. 4120.04, Gradation 11 if subdrains will not be installed. If subdrains are installed, then a free -draining crushed stone with less than 6% of material passing the U.S. No. 200 sieve (e.g. IDOT Section No. 4121, Gradation 12a) should be used as the aggregate subbase. After rough grade has been established, the exposed subgrade should be proofrolled by the contractor and observed by Terracon personnel prior to providing 1 foot of compacted structural fill discussed above. This surficial proofroll will assist in developing a stable base suitable for compaction of new structural fill, and can also assist in delineating low density, soft, or disturbed areas within the native soil or existing fill stratums. Soft or loose areas should be undercut, moisture conditioned, and recompacted or replaced with approved structural fill. Subgrade conditions should be observed by Terracon personnel during construction. Based on the materials encountered in the borings, it appears that some of the existing materials may be reused as structural fill. However, moisture conditioning and some sorting of organic material and rubble should be anticipated. Consideration could also be given to placing geogrid or woven geotextile below the aggregate base to assist in bridging small areas of localized subsidence and/or poor subgrade support. If there is a delay between subgrade preparation and paving, the pavement subgrades should be carefully re-evaluated as the time for pavement construction approaches. Within a few days of the scheduled paving, we recommend the pavement areas be proofrolled again with a loaded tandem axle dump truck in the presence of Terracon personnel. Particular attention should be given to the areas that were rutted and disturbed earlier during construction operations and frequent movement of construction equipment. Areas where unsuitable conditions exist should be repaired by removing and replacing the materials with properly compacted fill. 4.8.2 Minimum Pavement Thicknesses Traffic load information was not available at the time of this report; therefore, a.f_ormal pavement design is not provided.

A minimum 1.5 -inch surface course should be used on ACC pavements. 3. A 4 -inch (or greater) granular base is recommended below PCC pavements to help reduce potential for slab curl, shrinkage cracking, and subgrade "pumping" through joints. The estimated pavement sections provided in this report are minimums for the assumed design criteria, and as such, periodic maintenance should be expected. A maintenance program that includes surface sealing, joint cleaning and sealing, and timely repair of cracks and deteriorated areas will increase the pavement's service life. Additional engineering observation is recommended to determine the type and extent of a cost effective program. Even with periodic maintenance, some movements and related cracking may still occur and repairs may be required. As an option, thicker sections could be constructed to decrease future maintenance. All concrete for rigid pavements should have a minimum 28 -day compressive strength of 4,000 psi, and be placed with a maximum slump of 4 inches. Although not required for structural support, a minimum 4 -inch thick base course layer is recommended to help reduce potential for slab curl, shrinkage cracking, and subgrade "pumping" through joints. Proper joint spacing will also be required to prevent excessive slab curling and shrinkage cracking. All joints should be sealed to prevent entry of foreign material and dowelled when: necessary for load transfer. Where practical, we recommend "early -entry" cutting of crack -control joints in Portland cement concrete pavements. Cutting of the concrete in its "green" state typically reduces the potgntial for micro -cracking of the pavements prior to the crack control joints being formed; xorgpared to. cutting the joints after the concrete has fully set.

Exterior slabs should be anticipated to heave during winter months. If frost action needs to be eliminated in critical areas, we recommend the use of non -frost susceptible fill or structural slabs. As an alternative to extending the non -frost susceptible fill to the full frost depth, consideration can be made to placing extruded polystyrene or cellular concrete under a buffer of at least 2 feet of non -frost susceptible fill. 4.10 Additional Explorations The boring locations and depths were planned to provide information on the subsurface conditions at the site for the structure crossing the unnamed tributary as well as trail pavements and retaining walls. Additional borings and/or the evaluation of the soils' hydrogeological properties could be required for shallow foundation supported structures such as retaining walls, or for USACE approved flood protection walls. 5.0 GENERAL COMMENTS Terracon should be retained to review the final design plans and specifications so comments can be made regarding interpretation and implementation of our geotechnical recommendations in the design and specifications. Terracon also should be retained to provide observation and testing services during grading, excavation, foundation construction and other earth -related construction phases of the project. A The analysis and recommendations presented in this report are based upon the data, obtained from the borings performed at the indicated locations and from other information discussed in thil report. This report does not reflect variations that may occur between borings, across the site, ora due to the modifying effects of construction or weather. The nature and extent of such variations may not become evident until during or after construction. If variations appear, we should be immediately notified so that further evaluation and supplemental recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken.

A planned fourth boring was not performed per the request of the MWDG and the City, due to their having existing boring information by others in the area. The borings were extended to depths of about 37 to 47 feet below the existing grades. The boring locations were selected and laid out in the field by Terracon personnel. Distances from the boring locations to the reference features shown on the attached plan are approximate and were located using a handheld GPS (estimated horizontal accuracy of ±10 feet). The ground surface elevations indicated on the boring logs are also approximate (rounded to the nearest 1 foot), and were obtained by Terracon personnel by interpolating between the contours of the Johnson County GIS topographic contour map. True surface elevations at the boring locations could differ due to interpolation, and other differences could occur from superposing approximate boring locations on the topographic plan. The locations and elevations of the borings should be considered accurate only to the degree implied by the means and methods used to define them. The borings were drilled with an ATV -mounted, rotary drilling rig using continuous flight, hollow - stemmed augers and a mud rotary procedure to advance the boreholes. Samples were obtained using split -barrel sampling procedures (ASTM D1586). In the split -barrel sampling procedure, a standard 2 -inch O.D. split -barrel sampling spoon is driven into the ground with a, 1,40 -pound hammer falling a distance of 30 inches. A CME automatic SPT hammer was used to advance the split -barrel sampler in the borings performed for this project. A significantly greater efficiency is achieved with the automatic hammer compared to the conventional safety hammer operated with a cathead and rope. This higher efficiency has an appreciable effect on tate 8PT-N value. The effect of the automatic hammer's efficiency has been considered in the interpretation and analysis of the subsurface information for this report. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18 -inch penetration is recorded as the syandard penetration resistance value. These values are indicated on the boring logs at the corres'p'onding depths of occurrence. The samples were sealed and returned to the laboratory for testing and classification (ASTM D4220). Field logs of the borings were prepared by the drill crew. Each log included visual classification of the materials encountered during drilling as well as the driller's interpretation of the subsurface conditions between samples. The boring logs included with this report (ASTM D5434) represent an interpretation of the field logs by a geotechnical engineer and include modifications based on laboratory observation and tests on select samples. Responsive ■ Resourceful ■ Reliable Exhibit A-3 Preliminary Geotechnical Engineering Report 1 ��rracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Sediment samples were also obtained at seven locations selected by MWDG, with each location determined by handheld GPS. The samples were obtained from a Jon boat using an AMS 25 - pound SST bottom dredge, which samples from the river bottom to about one-half foot in depth. Before each sampling, the dredge was cleaned with a solution of Alconox and potable water. Three of the samples (S -DS, S -US -E, and S -US -W) were split in the field with portions turned over to Stanley Consultants, Inc. for analytical testing. Procedural standards noted above are for reference to methodology in general. In some cases variations to methods are applied as a result of local practice or professional judgment.

A hand penetrometer was used to estimate the unconfined compressive strength of some cohesive samples. The hand penetrometer provides a better estimate of soil consistency than visual examination alone. The following index tests were performed to aid in classifying the soils and evaluating their engineering properties: Two (2) Atterberg limits (liquid and plastic) tests (ASTM D4318). Two (2) organic content (loss on ignition) determinations (ASTM D2974); Nine (9) grain size analyses (washed over a U.S. No. 200 sieve) (ASTM D422). The results of the laboratory tests are shown on the boring logs, adjacent to the soil profiles, at their corresponding sample depths and/or as Exhibits B-2 and B-3. As a part of the laboratory testing program, the soil samples were classified in the laboratory (ASTM D2488) based on visual observation, texture, plasticity, and the limited laboratory testing described above. Additional testing could be performed to more accurately classify the samples. Portions of the recovered samples were placed in sealed containers, and the samples will be retained for at least 1 month in case additional testing is requested. The soil descriptions presented on the boring logs for native soils are in accordance with our enclosed General Notes and Unified Soil Classification System (USCS) (ASTM D2487). The estimated group symbol for the USCS is also shown on the boring logs, and a brief description of the Unifieg System is attached to this report. -Y `y Classification of rock materials is in accordance with the enclosed Description of Rock Properties and has been estimated from disturbed samples. Core samples and petrographic analysis may indicate other rock types. Procedural standards noted above are for reference to methodology in general. In some cases variations to methods are applied as a result of local practice or professional judgment.

Coarse Grained Soils have more than 50% of their dry classification weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and silts If they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined on the basis of their in-place relative density and fine-grained soils on the basis of their consistency. LOCATION AND ELEVATION NOTES_ Unless otherwise noted, Latitude and Longitude are approximately determined using a hand-held GPS device. The accuracy of such devices is variable. Surface elevation data annotated with +/- indicates that no actual topographical survey was conducted to confirm the surface elevation. Instead, the surface elevation was approximately determined from topographic maps of the area.

LIQUID LIMIT (LL) 1 rerracon rYl � 80 90 100 110 Exhibit C-2 GENERAL NOTES Sedimentary Rock Classification DESCRIPTIVE ROCK CLASSIFICATION: Sedimentary rocks are composed of cemented clay, silt and sand sized particles. The most common minerals are clay, quartz and calcite. Rock composed primarily of calcite is called limestone; rock of sand size grains is called sandstone, and rock of clay and silt size grains is called mudstone or claystone, siltstone, or shale. Modifiers such as shaly, sandy, dolomitic, calcareous, carbonaceous, etc. are used to describe various constituents. Examples: sandy shale; calcareous sandstone. LIMESTONE Light to dark colored, crystalline to fine-grained texture, composed of CaCoa, reacts readily with HCI. DOLOMITE Light to dark colored, crystalline to fine-grained texture, composed of CaMg(CO3)2, harder than limestone, reacts with HCI when powdered. CHERT Light to dark colored, very fine-grained texture, composed of micro -crystalline quartz (S102), brittle, breaks into angular fragments, will scratch glass. SHALE Very fine-grained texture, composed of consolidated silt or clay, bedded in thin layers. The uniaminated equivalent is frequently referred to as siltstone, claystone or mudstone. SANDSTONE Usually light colored, coarse to fine texture, composed of cemented sand size grains of quartz, feldspar, etc. Cement usually is silica but may be such minerals as calcite, iron -oxide, or some other carbonate. CONGLOMERATE Rounded rock fragments of variable mineralogy varying in size from near sand to boulder size but usually pebble to cobble size (rh inch to 6 inches). Cemented together with various cementing agents. Breccia is similar but composed of angular, fractured rock particles cemented together. in DEGREE OF WEATHERING: SLIGHT Slight decomposition of parent material on joints. May be color change. MODERATE Some decomposition and color change throughout. HIGH Rock highly decomposed, may be extremely broken. Classification of rock materials has been estimated from disturbed samples. Core samples and petrographic analysis may reveal other rock types. 1 erracon Fo,m 109-6 85 Exhibit C-3 Previous Soil Borings 4`1 s� AM t,.•lal q t'afN r a f Wim® 1 1" _ ism � s.• LEGEND t1 APPROXNATESOWNGLOCATION k -APPROXIM1 TESOWNGLOCATIONTERRACONPROI.NO.06W 16 NORTH PROPOSED BORING LOCATION PLAN EXHIBIT# -APPROXIMATE BOMNG LOCATION TERRACON PROM.

Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws.

p33vemBrt[s located on the west side of the Iowa River from Burlington Street to U.S. Highway 9 inr4awa City, Iowa. Terracon's geotechnical scope of work included the advancement of three test`5'orings to approximate depths of 36.5 to 47 feet below existing site grades, as well as sediment sampling in the Iowa River at seven locations. Information from other explorations performed along the alignment were also used to supplement this exploration. Based on the information obtained from our subsurface exploration, the site is suitable for development of the proposed project. The following geotechnical considerations were identified: ■ Significant depths (i.e. 7 to 13 feet) of uncontrolled existing fill were encountered along the trail alignment in the borings. Uncontrolled fill is not considered reliable for the support of structure foundations. Complete removal and replacement of the fill is not anticipated to be economical for this project. Structures such as the proposed bridge and retaining walls should therefore be supported on driven pile foundations. ■ If the box culvert alternative to the bridge is chosen at the creek crossing, a shallow mat foundation supported on native materials may be feasible. However, to adequately dewater the bearing soils during construction, a cofferdam and well points will likely be required. ■ The risk of poor trail pavement performance due to uncontrolled fill can be reduced with the recommended partial overexcavation and geotextile placement; however the designer and City should understand that the risk cannot be eliminated without completely removing the fill. ■ Portions of the existing fill materials could potentially be used as site grading fill; however, significant sorting to remove unsuitable materials, as well as moisture conditioning of the soils would be required. ■ Based on the limited subsurface information obtained during our site exploration, the 2012 International Building Code (IBC), seismic site classification for the proposed bridge or culvert site is C. ■ Earthwork on the project should be observed and evaluated by Terracon. The evaluation of earthwork should include observation and testing of engineered fill, subgrade preparation, foundation bearing materials, and other geotechnical conditions exposed during construction. ■ Only preliminary design information was available for the preparation of this report, therefore as the design advances additional recommendations will likely be required. Terracon should be provided plans at the schematic stage to determine if additional recommendations are Responsive ■ Resourceful ■ Reliable Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lrerracon required, and at the pre-bid stage to confirm that our recommendations have been properly implemented. ■ Our recommendations did not include design and construction of USACE approved flood protection structures. Additional field exploration, laboratory testing, and analyses would be required if the project will include flood protection. This summary should be used in conjunction with the entire report for design purposes. It should be recognized that details were not included or fully developed in this section, and the report must be read in its entirety for a comprehensive understanding of the items contained herein.

A Site Location Plan (Exhibit A-1), a Boring Location Plan (Exhibit A-2), a subsurface soil profile (Exhibit A-4) and logs of the borings (Exhibits A-5 to A-7) are included in Appendix A of this report. The results of the laboratory testing performed on soil samples obtained from the site during the field exploration are included on the boring logs and/or in Appendix B of this report. Descriptions of the field exploration and laboratory testing are included in their respective appendices. Terracon performed a prior subsurface exploration for a proposed pedestrian bridge (Terracon Project No. 06955103, Geotechnical Engineering Report dated October 19, 1995). The information from this prior exploration was also used in developing the preliminary recommendations contained in this report. The boring log from that exploration is also included in this report as Exhibit A-8. A planned fourth boring was not performed at the request of the client, McLaughlin Whitewater Design Group (MWDG), since the City of Iowa City (City) provided us with logs of borings performed by Team Services (TEAM Report No. 1-3398, dated October 9, 2013) on the 21 Benton Responsive ■ Resourceful ■ Reliable Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lrerracon Street property, which included borings on the proposed alignment.

Stratification boundaries on the boring logs represent the approximate location of_,Ghanges' in native soil and rock types; in situ, the transition between materials may be gradual. -Details for each of the borings can be found on the boring logs in Appendix A of this report. The subsurface conditions encountered in our exploration were generally similar to those found during our September 1995 exploration. Responsive ■ Resourceful ■ Reliable 4 Preliminary Geotechnical Engineering Report l��rr7con Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Sediments from the Iowa River bottom were fine to coarse and medium to coarse sands with trace gravel. The sand samples farthest downstream (S-1 and S-2) were "silty" and "with silt", respectively, while the remaining samples had trace silt. All the sediments were poorly graded. Plots of the particle size distribution are provided on Exhibits B-2 and B-3. 3.3 Groundwater Conditions The borings were observed for the presence of groundwater during drilling and sampling. The mud -rotary procedure introduces drilling fluid into the boreholes, making water level observations shortly after the completion of drilling (e.g. same day) unrepresentative. After completion of our drilling operation, the boreholes were backfilled with on-site soils. Water levels observations are presented in the table below. 0 WATER LEVEL OBSERVATIONS ^?

These water level observations provide an approximate indication of the groundwater conditions existing on the site at the time the observations were made. Longer-term observations using cased holes or piezometers, sealed from the influence of surface water, would be required for a better evaluation of the groundwater conditions along the alignment. Fluctuations of the groundwater levels will likely occur due to seasonal variations in the Iowa River stage, amount of rainfall, runoff, and other factors not evident at the time the borings were performed. Therefore, groundwater levels during construction or at other times in the life of the structure may be different than the levels indicated on the boring logs. The possibility of groundwater level fluctuations and perched water should be considered when developing the design and construction plans for the project. Responsive ■ Resourceful ■ Reliable Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lrerracon 4.0 RECOMMENDATIONS FOR DESIGN AND CONSTRUCTION 4.1 Geotechnical Considerations Based on the results of the subsurface explorations, laboratory testing, and our analyses, it is our opinion that the proposed bridge and retaining walls should be supported on deep foundations such as driven piles that extend to competent bedrock. If the box culvert alternative is chosen, a grade supported mat foundation appears feasible. Primary geotechnical considerations include: ■ Existing variable fill; ■ Bedrock variability; ■ Shallow groundwater; �_ r ■ Rubble zones and cobbles and boulders. <i—n r rn � Further details are provided herein. 0 4.1.1 Existing Uncontrolled Fill Existing fill was encountered in the borings to depths ranging from about 7 to 13 feet below existing grades. Based on the SPT results (N -values ranging from 1 to 16 blows per foot) and highly variable composition of the fill, it appears that the fill was not placed as engineered fill with consistent control of moisture and density. Records regarding fill placement were not provided to Terracon for the preparation of this report, and likely do not exist. As such, the existing fill should not be considered reliable for support of foundations, and risk of possible poor performance for trail pavements must be accepted if portions of the existing fill are allowed to remain in place as a cost saving measure. Support of pavements on or above existing fill soils is discussed in this report. However, even with the recommended construction testing services, there is an inherent risk for the City that highly compressible fill or unsuitable material within or buried by the fill will not be discovered. This risk of unforeseen conditions cannot be eliminated without completely removing the existing fill, but can be reduced by performing additional testing and evaluation. We anticipate that complete removal of the fill will not be economical for this project. Therefore, as a minimum to reduce some of the risk of abrupt differential settlement, we recommend at least 18 inches of granularfill be placed below pavements. A high -tensile geogrid could also be placed below the crushed limestone base course to further reduce the risk of abrupt differential settlement. 4.1.2 Soil Improvement Systems As an alternative to supporting retaining walls on deep foundations, they could be supported on existing fill materials that have been improved with methods such as "Geopier® Rammed Responsive ■ Resourceful ■ Reliable 6 Preliminary Geotechnical Engineering Report l�err7eon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Aggregate Piers", "Vibro-Replacement Stone Columnse'", or other similar aggregate pier systems that extend through the fill soils to suitable native soils. These soil improvement methods are proprietary systems designed by licensed contractors who could provide further information regarding these support options. Typically, foundations supported on aggregate pier improved soils can be designed with net allowable bearing pressures ranging from 3,000 to 6,000 psf. The design bearing pressure is provided by the aggregate pier designer/installer. 4.1.3 Bedrock Variability The depth to bedrock varied along the alignment from about 36 feet to a depth of more than 70 feet estimated based on our familiarity with bedrock conditions in the vicinity. Deep foundation lengths will vary along the alignment due to the varying depths to bedrock and degree of bedrock weathering. Additional borings and/or geophysical methods could be used to better evaluate bedrock depths along the alignment. Wherever deep foundations are planned, we recommend that the bid documents include an add/deduct line item to account for bedrock variations. 4.1.4 Shallow Groundwater Dewatering should be anticipated for deep excavations that extend to near or below Iowa River stage. Quick conditions will result in sandy soils if excavations extend below the water table and proper dewatering measures are not performed. If the box culvert alternative is chosen, we anticipate that a coffer dam and well points will be required for construction dewatering. N 4.1.5 Rubble Zones and Cobbles and Boulders Zones of both rubble/debris in fill sections and cobbles and boulders in native sand and grawl strata were encountered in the borings. These could act as obstructions during deep f4datkmr installation, requiring pre -drilling through fill sections, and/or requiring offset anftr 9dditional replacement piles. I� 4.2 Site Preparation and Earthwork ry w 4.2.1 Site Grading Pavements, topsoil, vegetation, uncontrolled fill consisting of rubble or debris, and any otherwise unsuitable materials should be removed from the construction areas. Excessively wet or dry material should either be removed or moisture conditioned and recompacted. Soft and/or low- density soil should be removed or compacted in place prior to placing new fill. After rough grade has been established (e.g. the planned overexcavation for minimum recommended 18 -inch crushed stone section), the exposed subgrade should be proofrolled by the contractor and test probed by Terracon. Proofrolling of sandy soils could be accomplished using a vibratory drum roller (gross weight of 10 tons or more), while clay subgrades could be accomplished using heavy, rubber -tired construction equipment or a tandem axle dump truck (gross weight of 20 to 25 tons). This surficial proofroll would help to provide a stable base for the Responsive ■ Resourceful ■ Reliable 7 Preliminary Geotechnical Engineering Report l�erraeon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 compaction of new structural fill, and delineates low density, soft, or disturbed areas that may exist below subgrade level. Unstable materials that cannot be satisfactorily improved by scarification and recompation should be removed and replaced with new structural fill. Subgrade conditions should be observed by Terracon during construction. Dewatering during construction could be required; design and deployment of dewatering measures are the responsibility of the contractor. We expect that sump pits and pumps would generally be adequate for dewatering excavations above the water table where perched water is present. More extensive dewatering measures, such as sheeting and well points will 4e�required for excavations extending below the water table, which is anticipated to be at to slight y above Iowa River stage. The groundwater level should be maintained at least 2 feet below the lowest excavation level. ;v Upon completion of filling and grading, care should be taken to maintain the subgrade moisture content prior to construction of pavements. Construction traffic over the completed subgrade should be avoided to the extent practical. Where practical, grading should be performed to prevent ponding of surface water on the prepared subgrades or in excavations. If the subgrade should become frozen, desiccated, saturated, or disturbed, the affected material should be removed or these materials should be scarified, moisture conditioned, and recompacted prior to pavement construction. 4.2.2 Soil Stabilization As previously discussed, the existing fill soils are anticipated to vary in composition, consistency/relative density, and strength. The City should budget for additional costs to provide the required corrective measures. If left in place, corrective measures will probably be required to increase subgrade stability during subgrade preparation. If the existing fill soils are left in-place, a layer of crushed limestone at least 18 inches thick should be placed below new pavements as previously discussed; however, a greater thickness could be required in some areas. A geotextile stabilization material could also be placed below the crushed stone to help stabilize the subgrade soils. To improve stability and create a stable base for compaction of new fill, we recommend the exposed soils be scarified, moisture conditioned and recompacted as discussed above. 4.2.3 Excavation Considerations All excavations should comply with the requirements of OSHA 29CFR, Part 1926, Subpart P, "Excavations" and its appendices, as well as other applicable codes. This document states that the excavation safety is the responsibility of the contractor. Reference to this OSHA requirement should be included in the project specifications. Slope heights, slope inclinations and/or excavation depths should in no case exceed those specked in local, state or federal safety regulations, including current OSHA excavation and trench safety standards. If any excavations extend to a depth greater than 20 feet (e.g. box culvert), side slopes and/or bracing must be designed by a professional engineer according to OSHA regulations. Responsive ■ Resourceful ■ Reliable 8 Preliminary Geotechnical Engineering Report l�errl�eon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Where granular soils are encountered, excavations will likely require shoring or bracing to maintain stability. The bracing or sheet piles should be designed to resist the lateral earth pressures and any adjacent surcharges while maintaining tolerable deformations, and would reduce the potential for caving or sloughing of these cohesionless soils. Sloped excavations could be considered if the lateral extent would not impact adjacent utilities, pavements or structures. Where poorly compacted variable fill materials are encountered, flatter slopes than those required by OSHA could be required to maintain the stability of the excavation(s). The information provided in this report is intended for its use by our client for this project only. Under no circumstances should the information provided below be interpreted to mean that Terracon is assuming responsibility for construction site safety or the contractor's activities; such responsibility is not being implied and should not be inferred. Construction site safety is the sole responsibility of the contractor, who shall also be solely responsible for the means, methods, and sequencing of construction operations. 4.2.4 Fill Material Requirements Fill placed in structure and pavement areas should be low plasticity cohesive soil or granular soil. Fill placed in confined excavations, utility trenches crossing pavements and structure foundation overexcavations should consist of relatively clean and well -graded granular material. This should provide for greater ease of placement and compaction in confined areas where larger compaction equipment cannot be operated. The use of granular fill in these isolated and potentially deeper excavations would reduce the potential for differential settlement. N C� The native sand soils encountered in the borings are considered suitable for use as sm mass grading fill. The clay soils from the fill sections could possibly be reused; howeyet, sahificanTj sorting will be required where zones of highly variable composition, organic materials, r?ble,� other deleterious material are encountered in the existing fill. �' `" Z rn ZZ Compacted structural fill should meet the following material property requirements - N) Fill Type USCS Classification Acceptable Location for Placement Low Plasticity CL -ML, CL, ML General site grading fill Cohesive' High Plasticity CUCH, CH, MH Green (non-structural) locations Cohesive GW, GP, GM, GC General site grading fill, below foundations, Granular SW, SP, SM, SC pavements Unsuitable CL -OL, OL, OH, CH -01-1, Green (non-structural) locations MH, PT Responsive ■ Resourceful ■ Reliable 9 Preliminary Geotechnical Engineering Report Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 lrerracon Fill Type USCS Classification Acceptable Location for Placement The on-site inorganic soils encountered in the On -Site Soils CL, CL -OL, SC, SM, SP borings generally appear suitable for reuse as structural fill.3 1. Structural fill should consist of approved materials that are free of organic matter and debris. Frozen material should not be used, and fill should not be placed on a frozen subgrade. A sample of each material type should be submitted to the geotechnical engineer for evaluation prior to use on this site. 2. Low plasticity cohesive soil would have a liquid limit less than 45 and a plasticity index of less than 23. 3. Fill materials used for proposed site grading should have less than 5 percent organic content. Appropriate laboratory tests, including Atterberg Limits for cohesive soils, organic content tests for dark colored soils and/or those that exhibit a noticeable odor, and standard Proctor (ASTM D698) moisture -density relationship tests should be performed on proposed fill materials prior to their use as structural fill. Further evaluation of any on-site soils or off-site fill materials should be performed by Terracon prior to their use in compacted fill sections. 4.2.5 Compaction Requirements Item Maximum Fill Lift Thickness ■ 9 inches or less in loose thickness when,heavy, self-propelled compaction equipment is used ■ 4 inches in loose thickness when hand -guided equipment (i.e. jumping jack or plate compactor) is used ■ 98% beneath foundations and within 1 foot of Minimum Compaction finished pavement subgrade Requirements"' ■ 95% above foundations and more than 1 foot below pavement subgrade ■ Low plasticity cohesive: -2% to +3% Moisture Content Range' ■ Granular: -3% to +3%4 1. As determined by the standard Proctor test (ASTM D698) 2. If the granular material is a coarse sand or gravel, or of a uniform size, or has a low fines content, compaction comparison to relative density may be more appropriate. In this case, granular materials should be compacted to at least 70% relative density (ASTM D 4253-00 and D 4254-00). 3. Moisture levels should be maintained at levels satisfactory for compaction to be achieved without the granular fill material bulking during placement or pumping when proofrolled. 4.2.6 Grading and Drainage Final surrounding grades should be sloped to provide effective drainage away from the top of retaining walls and pavements during and after construction. Grades around retaining walls and Responsive ■ Resourceful ■ Reliable 10 Preliminary Geotechnical Engineering Report 1 �err�eon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 pavements should also be periodically inspected and adjusted as necessary, as part of the structure's maintenance program. Water permitted to pond next to the retaining walls or on pavements can result in greater soil movements than those discussed in this report. These greater movements can result in unacceptable differential wall and pavement movements. Estimated movements described in this report are based on effective drainage for the life of the walls and pavements and cannot be relied upon if effective drainage is not maintained. 0 4.3 Deep Foundation Recommendations a_ Heavily loaded and/or settlement intolerant structures, such as the proposed bridge ,and retaining.— walls etaining.--walls should be supported on driven pile foundations. Augercast piles were considerer7;however,l i due to the relatively shallow depth to bedrock over portions of the alignment as well loose sands -� being present, only a relatively low capacity would be developed. Drilled shafts could al; b be considered; however, construction through the existing fill materials and water bearing san"oils would require a combination of casing and slurry drilling. We can provide design and construction recommendations for augercast piles and shafts upon request. 4.4 Driven Pile Foundations Steel H -piles or pipe piles driven to practical refusal in the limestone bedrock could be used for support of the bridge and retaining wall structures. Driven piles will derive their compressive load capacities from end bearing in the underlying bedrock. In our opinion, where piles will be driven near existing structures or other improvements, H -piles should be used instead of pipe piles to reduce lateral movement and heave of the soils. Preliminary allowable design compressive load capacities of driven steel piles could be calculated by taking the allowable steel working stress of 15 kips per square inch (ksi) for piles driven to refusal times the cross-sectional steel area. However, we recommend that the steel have a f mtn of at least four (4) times the working stress (e.g. a pile designed for 15 ksi should have a Py mi. of 60 ksi) to reduce the potential for damage to the piles during driving. For example, an HP 10x42 pile could be used for this project and an allowable design load of about 185 kips could be used for piles driven to practical refusal in the underlying limestone bedrock. Typical rock penetration for driven piles will vary based on pile size and location across the building area, but is estimated to small. Individual pile settlement should be on the order of/cinch when designed according to the criteria presented in this report. Differential settlement between individual piles can typically be estimated at 1/2 to % the total settlement.

An allowable passive resistance of 6 kips is recommended for driven steel H -piles, if a detailed lateral load analysis is not performed. Preliminary input values for LPILE are provided below. We can provide input parameters for other analysis programs and/or perform the LPILE analysis upon request. Recommended input values for use in LPILE analyses that represent the materials encountered in the borings are shown on the table below. LPILE will estimate values of k h and E5o based on strength; however, non -default values of kh should be used where provided. Since deflection or a service limit criterion will most likely control lateral capacity design, no safety/resistance factor is included with these parameters. Our recommendations are based on Boring B-10abeing toe controlling case for maximum lateral deflection; LPILE input parameters can be provided for other borings upon request.

We can provided guidance for p -y multipliers if detailed analyses using LPILE are planned. Pile/Shaft Spacing (Diameters) Reduction Factors 6D 1.0 4D 0.85 3D 0.65 The piles should be spaced the greater of at least three pile flange widths or web heights (for H - piles) or diameters (for pipe piles) apart (center -to -center) if they will be used to resist lateral loads. Pile caps and/or grade beams could be subject to uplift loading due to frost action; thus, perimeter foundation elements beneath unheated areas should extend at least 4 feet below the lowest adjacent finished grade for frost protection. It should be noted that the load capacities provided herein are based on the stresses induced in the supporting soil and rock strata. The structural capacity of the piles should be checked to assure that they can safely accommodate the combined stresses induced by axial and lateral forces. Lateral deflections of piles should be evaluated using an appropriate analysis method, and will depend upon the pile's diameter, length, configuration, stiffness and "fixed head" or "Free head" condition. We can provide additional analyses and estimates of lateral deflections for specific loading conditions upon request. The load -carrying capacity of piles may be increased by increasing the section (for H -piles), diameter (for pipe piles) and/or length. $Y 4.4.2 Construction Considerations — Driven Piles ' % r'-' The contractor should select a driving hammer and cushion combination wirva-Is cpabre qf installing the selected piling without overstressing the pile material. The hammer shourd have rated energy in foot-pounds at least equal to 15 percent of the design compresskwloa'gcap in pounds. The contractor should submit the pile driving plan and the pile hammer -cushion combination to the engineer for evaluation of the driving stresses in advance of pile installation. During driving, a maximum of 10 blows per inch is recommended to reduce the potential of damage to the driving system. If practical refusal is experienced above the anticipated rock surface elevation, then the pile may be on a boulder or other obstruction and a replacement pile should be driven. If this occurs, the situation should be evaluated by Terracon during the pile driving operations. Difficult driving could also be encountered in the weathered rock. Consideration should be given to using protective points and/or flange stiffening if H -piles are used. The contractor should be prepared to cut or splice piles, as necessary. Splicing of piles should be in accordance with specifications provided by the project structural engineer.

A Terracon representative should observe pile driving operations. Each pile should be observed and checked for buckling, crimping and alignment in addition to recording penetration resistance, depth of embedment, and general pile driving operations. The existing adjacent structures and subsurface utilities should be observed prior to pile installation to document their condition. These structures should also be observed during pile installation for any indications of movement. Pile driving should be stopped and Terracon contacted if movement or cracking of the existing structures is observed. Monitoring vibration levels during pile driving should be considered. It should be understood that although vibrations from pile driving may be below levels that will cause structural damage, they may be felt by occupants of the adjacent buildings. The potential impact of driving piles at this site should be considered when evaluating this alternative. Terracon is able to perform vibration monitoring upon request. 4.5 Box Culvert Foundations If a box culvert is used instead of a bridge for the unnamed tributary to the Iowa River crossing, we anticipate that it would be a reinforced concrete box (RCB) culvert with a bottom elevation near 635 feet. 4.5.1 Box Culvert Design Recommendations DESCRIPTION VALUE Foundation fvne .

We anticipate that a cofferdam and diversion of flow through the unnamed tributary will be needed to construct the culvert. Groundwater levels should be maintained at least 2 feet below the proposed excavation grades to reduce disturbance of the bearing soils. This will likely require the use of well points to lower the water table within the cofferdam. It should be noted that "quick" conditions will result in sandy soils if excavations extend below the water table and proper dewatering measures are not performed. This would significantly reduce the bearing capacity of the subgrade soils and may result in subsequent settlement of the culvert and overlying trail pavement. The specifications should include a performance requirement for the construction dewatering system. Construction and backfilling of the box culvert should be conducted well in advance of the trail pavement construction. This will allow expected settlement to occur without causing premature pavement distress. For an asphaltic cement concrete pavement section, consideration could be given to placing the base course and then the surface course at a later date. Where lower strength soils and/or loose sands cannot be densified in place and/or if unsuitable bearing soils are encountered along the culvert foundation excavation, the excavation should be extended deeper to suitable soils and the culvert should bear on properly compacted structural backfill extending down to the suitable soils. Overexcavation for compacted backfill placement below the culvert should extend laterally beyond its edges at least 8 inches per foot of overexcavation depth. The overexcavation should then be backfilled up to the culvert's base elevation with well -graded granular material placed in lifts of 6 inches or less in loose thickness and compacted to at least 98 percent of the material's maximum Standard Proctor dry density (ASTM D698). kwo.

The current scope does not include a 100 foot soil profile determination. Borings extended to a maximum depth of 62 feet, and this seismic site class definition considers that Moderately weathered bedrock continues below the maximum depth of the subsurface exploration. Additional exploration 1:6 deeper depths, or seismic velocity testing would be required to confirm the conditions below the curreht depth of exploration. 4.7 Lateral Earth Pressures cn Reinforced concrete walls with unbalanced backfill levels on opposite sides, such as retaining walls, should be designed for earth pressures at least equal to those indicated in the following table. Earth pressures will be influenced by structural design of the walls, conditions of wall restraint, methods of construction and/or compaction and the strength of the materials being restrained. Two wall restraint conditions are shown. Active earth pressure is commonly used for design of free-standing cantilever retaining walls and assumes wall movement. The "at -rest" condition assumes no wall rotation and should be used where the wall's geometry restrains them from movement. The surcharge components would apply where drives, surface parking or other loading will be applied adjacent to the below grade walls. The recommended design lateral earth pressures are for cast -in-place concrete walls only, do not include a factor of safety, and do not include any provision for possible hydrostatic pressure on the walls. These recommendations are not applicable to the design of modular block - geogrid reinforced backfill walls, and additional analyses and evaluation would be required for these walls.

Backfill placed against structures should consist of granular soils or low plasticity cohesive soils. For the granular values to be valid, the granular backfill must extend out and up from the base of the wall at an angle of at least 45 and 60 degrees from vertical for the active and passive cases, respectively. Heavy construction equipment should not operate within a distance closer than the exposed height of retaining walls to prevent lateral pressures greater than those provided. Backfill placed in non-structural areas adjacent to the walls should be placed in thin lifts and compacted using hand -operated equipment to at least 95 percent, but no more than 100 percent, of the material's maximum standard Proctor dry density (ASTM D 698). Wall drainage and the potential for hydrostatic pressure should be carefully considered in preparing final plans for the retaining walls constructed within the flood plain of the Iowa River. Walls incorporated with flood protection should be designed for hydrostatic pressures. Walls not associated with flood protection should have effective drainage such that rises and falls of the river stage will be mirrored in the backfill zone. Filtration will be an important consideration to reduce losses from the backfill zone through weep -holes or other wall perforations due to fluctuations in water levels. Terracon should be retained to provide further consultation once wall profiles and design intents are determined. Combined hydrostatic and lateral earth pressures for lean clay backfill can be calculated using an equivalent fluid weighing 90 and 100 pd for active and at -rest conditions, respectively. For granular backfill, an equivalent fluid weighing 85 and 90 pd should be used for active a3nd at -rest, respectively. These pressures do not include the influence of surcharge, equipment or pavement loading. 4.8 Trail Design and Construction Recommendations Traffic volumes and loading conditions were not provided. We understand the proposed trail will primarily be used by pedestrians and bicyclists; however, maintenance vehicles such as small (i.e. gross weight under 20 tons) single -axle dump trucks could occasionally use the trail. 4.8.1 Trail Subgrade Preparation As previously discussed, existing fill from about 7 to 13 feet deep is anticipated along most of the trail alignment, therefore complete removal of the existing fill is not expected to be economically feasible. Therefore, as a minimum, we recommend placing at least 1 foot of properly compacted granular fill below the recommended 6 -inch thick crushed limestone aggregate base. The upper Responsive ■ Resourceful ■ Reliable 18 Preliminary Geotechnical Engineering Repoli l��rr�con Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 1 foot of subgrade material should be placed on stable portions of the existing fill, and should be compacted to at least 98 percent of the material's maximum dry density as determined by ASTM D698. In addition, we recommend the aggregate base consist of a dense -graded crushed stone meeting IDOT Section No. 4120.04, Gradation 11 if subdrains will not be installed. If subdrains are installed, then a free -draining crushed stone with less than 6% of material passing the U.S. No. 200 sieve (e.g. IDOT Section No. 4121, Gradation 12a) should be used as the aggregate subbase. After rough grade has been established, the exposed subgrade should be proofrolled by the contractor and observed by Terracon personnel prior to providing 1 foot of compacted structural fill discussed above. This surficial proofroll will assist in developing a stable base suitable for compaction of new structural fill, and can also assist in delineating low density, soft, or disturbed areas within the native soil or existing fill stratums. Soft or loose areas should be undercut, moisture conditioned, and recompacted or replaced with approved structural fill. Subgrade conditions should be observed by Terracon personnel during construction. Based on the materials encountered in the borings, it appears that some of the existing materials may be reused as structural fill. However, moisture conditioning and some sorting of organic material and rubble should be anticipated. Consideration could also be given to placing geogrid or woven geotextile below the aggregate base to assist in bridging small areas of localized subsidence and/or poor subgrade support. If there is a delay between subgrade preparation and paving, the pavement subgrades should be carefully re-evaluated as the time for pavement construction approaches. Within a few days of the scheduled paving, we recommend the pavement areas be proofrolled again with a loaded tandem axle dump truck in the presence of Terracon personnel. Particular attention should be given to the areas that were rutted and disturbed earlier during construction operations and frequent movement of construction equipment. Areas where unsuitable conditions exist should be repaired by removing and replacing the materials with properly compacted fill. 4.8.2 Minimum Pavement Thicknesses Traffic load information was not available at the time of this report; therefore, a formal pdvement design is not provided. As a minimum, we suggest the following typical pavement secjions be considered.

Exterior slabs should be anticipated to heave during winter months. If frost action needs to be eliminated in critical areas, we recommend the use of non -frost susceptible fill or structural slabs. As an alternative to extending the non -frost susceptible fill to the full frost depth, consideration can be made to placing extruded polystyrene or cellular concrete under a buffer of at least 2 feet of non -frost susceptible fill. 4.10 Additional Explorations The boring locations and depths were planned to provide information on the subsurface coDditions._ at the site for the structure crossing the unnamed tributary as well as trail pavements.at,d retaining`" walls.

Terracon also should be retained to provide observation and testing services during grading, excavation, foundation construction and other earth -related construction phases of the project. The analysis and recommendations presented in this report are based upon the data obtained from the borinas oerformed at the indicated locations and from other information discussed in this report. This report does not reflect variations that may occur between borings, across the site, or due to the modifying effects of construction or weather. The nature and extent of such variations may not become evident until during or after construction. If variations appear, we should be immediately notified so that further evaluation and supplemental recommendations can be provided. The scope of services for this project does not include either specifically or by implication any environmental or biological (e.g., mold, fungi, bacteria) assessment of the site or identification or prevention of pollutants, hazardous materials or conditions. If the owner is concerned about the potential for such contamination or pollution, other studies should be undertaken.

Preliminary Geotechnical Engineering Report 1 Terracon Iowa River Improvements ■ Iowa City, Iowa January 12, 2015 ■ Terracon Project No. 06145620.01 Field Exploration Description Our field exploration consisted of performing three soil borings at the project site. A planned fourth boring was not performed per the request of the MWDG and the City, due to their having existing boring information by others in the area. The borings were extended to depths of about 37 to 47 feet below the existing grades. The boring locations were selected and laid out in the field by Terracon personnel. Distances from the boring locations to the reference features shown on the attached plan are approximate and were located using a handheld GPS (estimated horizontal accuracy of ±10 feet). The ground surface elevations indicated on the boring logs are also approximate (rounded to the nearest 1 foot), and were obtained by Terracon personnel by interpolating between the contours of the Johnson County GIS topographic contour map. True surface elevations at the boring locations could differ due to interpolation, and other differences could occur from superposing approximate boring locations on the topographic plan. The locations and elevations of the borings should be considered accurate only to the degree implied by the means and methods used to define them. The borings were drilled with an ATV -mounted, rotary drilling rig using continuous flight, hollow - stemmed augers and a mud rotary procedure to advance the boreholes. Samples were obtained using split -barrel sampling procedures (ASTM D1586). In the split -barrel sampling procedure, a standard 2 -inch O.D. split -barrel sampling spoon is driven into the ground with a 140 -pound hammer falling a distance of 30 inches. A CME automatic SPT hammer was used to advance the split -barrel sampler in the borings performed for this project. A significantly greater efficiency is achieved with the automatic hammer compared to the conventional safety hammer operated with a cathead and rope. This higher efficiency has an appreciable effect on the SPT -N value. The effect of the automatic hammer's efficiency has been considered in the interpretation and analysis of the subsurface information for this report. The number of blows required to advance the sampling spoon the last 12 inches of a normal 18 -inch penetration is recorded as the standard penetration resistance value. These values are indicated on the boring logs at the corresponding depths of occurrence. The samples were sealed and returned to the laboratory for testing and classification (ASTM D4220). Field logs of the borings were prepared by the drill crew. Each log included visual classification of the materials encountered during drilling as well as the driller's interpretation of the subsurface conditions between samples. The boring logs included with this report (ASTM D5434) represent an interpretation of the field logs by a geotechnical engineer and include laboratory observation and tests on select samples.

'The following index tests were performed to aid in classifying the soils and evaluating their engineering properties: ■ Two (2) Atterberg limits (liquid and plastic) tests (ASTM D4318). ■ Two (2) organic content (loss on ignition) determinations (ASTM D2974); ■ Nine (9) grain size analyses (washed over a U.S. No. 200 sieve) (ASTM D422). The results of the laboratory tests are shown on the boring logs, adjacent to the soil profiles, at their corresponding sample depths and/or as Exhibits B-2 and B-3. As a part of the laboratory testing program, the soil samples were classified in the laboratory (ASTM D2488) based on visual observation, texture, plasticity, and the limited laboratory testing described above. Additional testing could be performed to more accurately classify the samples. Portions of the recovered samples were placed in sealed containers, and the samples will be retained for at least 1 month in case additional testing is requested. The soil descriptions presented on the boring logs for native soils are in accordance with our enclosed General Notes and Unified Soil Classification System (USCS) (ASTM D2487). The estimated group symbol for the USCS is also shown on the boring logs, and a brief description of the Unified System is attached to this report. Classification of rock materials is in accordance with the enclosed Description of Rock Properties and has been estimated from disturbed samples. Core samples and petrographic analysis may indicate other rock types. Procedural standards noted above are for reference to methodology in general. In some cases variations to methods are applied as a result of local practice or professional judgment.

In low permeability soils, accurate determination of groundwater levels is not possible with short term water level observations. Grab Sample Recovery DESCRIPTIVE SOIL CLASSIFICATION Soil classification is based on the Unified Soil Classification System. Coarse Grained Soils have more than 50% of their dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand. Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and silts if they are slightly plastic or non-plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse-grained soils are defined on the basis of their in-place relative density and fine-grained soils on the basis of their consistency. LOCATION AND ELEVATION NOTES Unless otherwise noted, Latitude and Longitude are approximately determined using a hand-held GPS device. The accuracy of such devices is variable. Surface elevation data annotated with +/- indicates that no actual topographical survey was conducted to confirm the surface elevation. Instead, the surface elevation was approximately determined from topographic maps of the area.

The most common minerals are clay, quartz and calcite. Rock composed primarily of calcite is called limestone; rock of sand size grains Is called sandstone, and rock of clay and silt size grains is called mudstone or claystone, siitstone, or shale. Modifiers such as shaly, sandy, dolomitic, calcareous, carbonaceous, etc. are used to describe various constituents. Examples: sandy shale; calcareous sandstone. LIMESTONE Light to dark colored, crystalline to fine-grained texture, composed of CaCo3, reacts readily with HCI. DOLOMITE Light to dark colored, crystalline to fine-grained texture, composed of CaMg(CO3)2, harder than limestone, reacts with HCI when powdered. CHERT Light to dark colored, very fine-grained texture, composed of micro -crystal line quartz (Sl0z), brittle, breaks into angular fragments, will scratch glass. SHALE Very fine-grained texture, composed of consolidated silt or clay, bedded in thin layers. The unlaminated equivalent is frequently referred to as siitstone, claystone or mudstone. SANDSTONE Usually Iioht colored, coarse to fine texture, composed of cemented sand size -Grains of quartz, feldspar, etc. Cement usually is silica but may be such minerals as calcite, iron -oxide, or some other carbonate. CONGLOMERATE Rounded rock fragments of variable mineralogy varying in size from near sand to boulder size but usually pebble to cobble size (Yz inch to 6 inches). Cemented together with various cementing agents. Breccia is similar but composed of angular, fractured rock particles cemented together. DEGREE OF WEATHERING: SLIGHT Slight decomposition of parent material on joints. May be color change. MODERATE Some decomposition and color change throughout. HIGH Rock highly decomposed, may be extremely broken. Classification of rock materials has been estimated from disturbed samples. Core samples and petrographic analysis may reveal other rock types. 1 rerracvn ro,m,oe--e,as Exhibit C-3 FILED 2019 JAH 22 Illi 11: 11 CITY CLr=P MINA CITY, in N'a LOG OF BORING NO. 1 Page 1 o€2 OWNERENGINEER City of Iowa City Howard R.

Activities required for the construction, maintenance, repair, and removal of utility lines and associated facilities in waters of the United States, provided the activity does not result in the loss of greater than 1/2 -acre of waters of the United States for each single and complete project. Utility lines: This NWP authorizes discharges of dredged or fill material into waters of. the United states and structures or work in navigable waters for crossings of those waters associated with the construction, maintenance, or repair of utility lines, including outfall and intake structures. There meet be no change in pre -construction contours of waters of. the United States. A "Utility line" is defined as any pipe or pipeline for the transportation of any gaseous, liquid, liquescent, or slurry substance, for any purpose, and any cable, line, or wire for the transmission for any purpose of electrical energy, telephone, and telegraph mensages, and internet, radio, and television communication. The term "utility line" does not include activities that drain a water of the United States, such as drainage till or french drains, but it does apply to pipes conveying drainage from another area. Material resulting from trench excavation may be temporarily-idecast into waters of the United States for no more than three months, provided the material is not pieced in such a maturer that it is dispersed by currents or other forces. The district engineer may extend the period of temporary side casting for no more thou a total of 180 days, where appropriate. in wetlands, the top 6 to 12 inches of the trench should normally be backfilled with topsoil from the trench. The trench cannot be constructed or backfilled in such a manner an to drain waters of the united States (e.g., backfilling with extensive gravel layers, creating a french drain effect). Any exposed slopes and stream banks =at be stabilized immediately upon completion of the utility line crossing of each waterbody. Utility line substations: This NNP authorizes the construction, maintenance, or expansion of substation facilities associated with a power line or utility line in non -tidal waters of the United States, provided the activity, in combination with all other activities included in one single and complete project, does not result in the loss of greater than 1/2 -acre of waters of the United States. This NNP does not authorize discharges into non -tidal wetlands adjacent to tidal waters of the United States to construct, maintain, or expand substation facilities.

Access roads moat be constructed so that the length of the road minimizes any adverse effects on waters of the United states and must be as near as possible to pre -construction contours and elevations (e.g., at grade corduroy roads or geotextile/gravel roads). Access roads constructed above pre-conetruction contours and elevations in waters of the United states meet be properly bridged or culverted to maintain surface flows. This NNP may authorize utility lines in or affecting navigable waters of the United States even if there is no associated discharge of dredged or fill material (See 33 CFR part 322). Overhead utility lines constructed over section 10 waters and utility lines that are routed in or under section 10 waters without a discharge of dredged or fill material require a section 10 permit. This NWP authorizes, to the extant that Department of the Army authorization is required, temporary structures, fills, and work necessary for the remediation of inadvertent returns of drilling fluids to waters of. the United States through sub -Boil fissures or fractures that alight occur during horizontal directional drilling activities conducted for the purpose of installing or replacing utility lines. These remediation activities must be done as soon as practicable, to restore the affected waterbody. District engineers may add special conditions to this NWP to require a remediation plan for addressing inadvertent returns of drilling fluids to waters of the United States during horizontal directional drilling activities conducted for the purpose of installing or replacing utility lines. This NWP also authorizes temporary structures, fills, and work, including the use of temporary mate, necessary to conduct the utility line activity. Appropriate measures must be taken to maintain normal downstream flows and minimise flooding to the maximum extent practicable, when temporary atructuree, work, and discharges, including cofferdams, are necessary for construction activities, access fills, or dewatering of construction sites. Temporary fills must consist of materials, and be placed in a manner, that will not be eroded by expected high flows. After construction, temporary fills must be removed in their entirety and the affected areae returned to Pre -construction elevations, The areas affected by temporary fills must be revegetated, as appropriate. Notification: The permittee must submit a pre -construction notification to the district engineer prior to commencing the activity if any of the following criteria are met: (1) The activity involves mechanized land clearing in a forested wetland for the utility line right-of- way; (2) a section 10 permit is required; (3) the utility line in waters of the United states, excluding overhead linea, exceeds 500 feed (4) the utility line is placed within a jurisdictional area (i.e., water of the united States), and it rune parallel to or along a stream bed that is within that jurisdictional area; (5) discharges that result in the loss of greater than 1!10- acre of waters of the United States; (6) permanent access roads are constructed above grade in waters of the United States for a distance of more than 500 feet; or (7) permanent access roads are constructed in waters of the United States with impervious materials, (see general condition 32.)

Fxcept for the relocation of non -tidal waters on the project site, this NWB does not authorize the conversion of a stream or natural wetlands to another aquatic habitat type (e.g., the conversion of a stream to wetland or vice versa) or uplands. Changes in wetland plant communities that occur when wetland hydrology is more fully restored during wetland rehabilitation activities are not considered a conversion to another aquatic habitat type. This NWP does not authorize stream channelizati.on. This NWP doom not authorize the relocation of tidal waters or the conversion of tidal waters, including tidal wetlands, to other aquatic uses, such as the conversion of tidal wetlands into open water impoundments, Compensatory mitigation is not required for activities authorized by this NWP since these activities must result in net increases in aquatic resource functions and services. Reversion. For enhancement, restoration, and establishment activities conducted: (111n accordance with the terms and conditions of a binding stream or wetland enhancement or restoration agreement, or a watland establishment agreement, between the landowner and the U.S. Fish and wildlife Service (FWS), the Natural Resources Conservation Service (MRCS), the from Service Agency (FSA), the National Marine Fisheries Service (NMFS), the National Ocean Service (NOS), U.S. Forest Service ((1SFS), or their designated state cooperating agencies; (2)as voluntary wetland restoration, enhancement, and establishment actions documented by the NRCS or USDA T�sehbical Service Provider pursuant to NRCS Field Office Technical Guide standards; or (3)on reclaimed surface coal mine lands, in accordance with a Surface Mining Control and Reclamation Act permit issued by the Office of surface Mining Reclamation and [enforcement (OSM.RE) or the applicable state agency, this NWP also authorizes any future discharge of dredged or fill material associated with the reversion of the area to its documented prior condition and use (i.e., prior to the restoration, enhancement, or establishment activities). The reversion caret occur within five years after expiration of a limited term wetland restoration or establishment agreement or permit, and is authorized in these circumstances even if the discharge occurs after this NWP expires. The five-year reversion limit does not apply to agreements without time limits reached between the landowner and the FWS, NRCS, FSA, LAMPS, NOS, USFS, or all appropriate state cooperating agency. This NWP also authorizes discharges of dredged or fill material in waters of the United States for the reversion of wetlands that were restored, enhanced, or established an prior -converted cropland or on uplands, in accordance with a binding agreement between the landowner and NRCS, PSA, FWS, or their designated state cooperating agencies (even though the restoration, enhancement, or establishment activity did rut require a section 404 permit). The prior condition will be documented in the original agreement or permit, and the determination of return to prior conditions will be made by the Federal agency or appropriate state agency executing the agreement or permit. Before conducting any reversion activity the permittee or the appropriate Federal or state agency muat notify the district engineer and include the documentation of the prior condition. once an area has reverted to its prior physical condition, .it will be subject to whatever the Corps Regulatory requi.rement.s .are applicable to that ,type of land at the time, The requirement that the act'ivit'y results in a net increase in aquatic_=:tesource functions and services does not apply to reversion activities meeting the above conditien7. Except for the activities described above, this NWP doom not authorize any future discharge of-- dredged f--dredged or fill material associated with the reversion of the area to its prior condition,. 2n ouch cases a separate permit would be required for any reversion. Reporting. For those activities that do not require pre -cons tnution notification, t* -~•^ permittee must submit to the district engineer a copy of: (1) The binding stream enhancra{ent or restoration agreement or wetland enhancement, restoration, or establishment agreement, or a project description, including project plans and location map; (2) the NRCS or USDA Techtiical' 7 Service Provider documentation for the voluntary stream enhancement or restoration action or. _J wetland restoration, enhancement, or establishment action; or (3) the SMCRA permit issSgd by J OSMRE or the applicable state agency. The report must also include information on baselipe ecological conditions on the project site, such as a delineation of wetlands, streams„ a)x)/or other aquatic habitats. These documents must be submitted to the district engineer at least 30 days prior to commencing activities in waters of the United States authorized by this NWP. Not.ficatioai The permittee must submit a pre -construction notification to the district engineer prior to commencing any activity (see general condition 32), except for the following activities: (1) Activities conducted on non -Federal public lands and private lands, in accordance with the terms and conditions of a binding stream enhancement or restoration agreement or wetland enhancement, restoration, or establishment agreement between the landowner and the FWS, MRCS, FSA, NMFS, NOS, USFS or their designated state cooperating ageneiesl (2) voluntary stream or wetlandrestoration or enhancement action, or wetland establishment action, documented by the NRCS or USDA Technical Service provider pursuant to NRCS Field Office Technical Guide standards; or (3) The reclamation of surface coal mine lands, in accordance with an SMCRA permit issued by the OSMRR or the applicable state agency. However, the permittee must submit a copy of the appropriate documentation to the district engineer to fulfill the reporting requirement. lAuthoritiea: Sections 10 and 404) Note: This NWP can be used to authorize compensatory mitigation projects, including mitigation banks and in -lieu fee projects. However, this NwP does not authorize the reversion of an arae used for a compensatory mitigation project to its prior condition, since compensatory mitigation is generally intended to be permanent. 20.

Such activities include, but are not limited to, plowing or dieting to impede succession, preparing seed beds, or establishing fire breaks. Sufficient riparian areas must be maintained adjacent to all open water bodies, including streams, to preclude water quality degradation due to erosion and sedimentation, This NWP does not authorize the construction of new dikes, roads, water control structures, or similar features associated with the management areae. The activity must not result in a net lose of aquatic resource functions and services. This NWP does not authorize the conversion of wetlands to uplands, impoundments, or other open water bodies. (Authocityt Section 404) Note: The repair, maintenance, or replacement of existing water control structures or the repair or maintenance of dikes may be authorized by NWP 3. Some such activities may qualify for an exemption under Section 404(f) of the Clean Water Act (sea 33 CFR 323.4). 31. Maintenance of Existing Flood Control Facilities. Discharges of dredged or fill material resulting from activities associated with the maintenance of existing flood control facilities, including debris basins, retention/ detention basins, levees, and channels that: (i) Were previously authorized by the Corps by individual permit, general permit, or 33 CFR 330.3, or did not require a permit- at the time they were constructed, or (ii) were constructed by the Corps and transferred to a non- Federal sponsor for operation and maintenance. Activities authorised by this NWP are limited to those resulting from maintenance activities that are conducted within the "maintenance baseline," as described in the definition below. Discharges of dredged or fill materials associated with maintenance activities in flood control facilities in any watercourse that have previously been determined to be within the maintenance baseline are authorized under this NWP. To the extent that a Corps permit is required, this NNP authorizes the removal 11 vegetation from levees associated with the flood control project. This NWP does not authorsxe the removal of nediment and associated vegetation from natural water courses except when they e' activities have been included in the maintenance baseline. All dredged and excavated material - must be deposited and retained in an area that ties no waters of the United States -unless 1 : 1 otherwise specifically approved by the district engineer under separate authorization. pyyper sediment controls must be used. ) '\J Maintenance Baseline: The maintenance baseline is a description of the phyaI' I characteristics (e.g.. depth, width, length, location, configuration, or design flood uapadityy etc.) of a flood control project within which maintenance activities are normally authorized`by7 NWP 31, subject to any came -specific conditions required by the district engineer.. The.district7 10 enyinmer will approve the maintenance baseline based on the approved or constructed capacity of the flood control facility, whichever is smaller, including any areas where there are no constructed channels but which are part of the facility. The proapecLive permittee will provide documentation of the physical characteristics of the flood control facility (which will normally consist of aa -built or approved drawings) and documentation of the approved and constructed design capacities of the flood control facility. if no evidence of the constructed capacity exists, the approved capacity will be used. The documantation will also include best management practices to ensure that the adverse environmental impacts caused by the maintenance activities are no more than minimal, especially in maintenance areas where there are no Constructed channels. ('Phe Corps may request maintenance records in areas where there has not been recent maintenance.) Revocation or modification of the final determination of the maintenance baseline can only be done is accordance with 33 CPR 330.5. Except in emergencies as described below, this NWP cannot be used until the district engineer approves the maintenance baseline and dsterminee tate need for mitigation and any regional or activity -specific conditions. Once determined, the maintenance baseline will remain valid for any subsequent reiasuanca of this NWP. This NWP does not authorize maintenance Of a flood control facility that ham been abandoned, A flood control facility will be Considered abandoned if it has operated at a significantly reduced capacity without needed maintenance being accomplished in a timely manner. A flood control facility will not be considered abandoned if the prospective permittee is in the process of obtaining other authorizations or approvals required for maintenance activities and is experiencing delays in obtaining theme authorisations or approvals. Mitigation: The district engineer will determine any required mitigation ore- time only for impacts associated with maintenance work at the acme time that the maintenance baseline is approved. Such one-time mitigation will be required when necessary to ensure that adverse environmental effects are m more than minimal, both individually and cumulatively. Such mitigation will only be required once for any specific reach of a flood control project. However, if one-time mitigation Is required for impacts associated with maintenance activities, the district engineer will not delay needed maintenance, provided the district engineer and the permittee establish a schedule for identification, approval, development, construction and Completion of any such required mitigation. Once the one-time mitigation described above has been completed, or a determination made that mitigation is not required, no further mitigation will be required for maintenance activities within the maintenance baseline (see Note, below). In determining appropriate mitigation, the district engineer will give special consideration to natural water courses that have been included in the maintenance baseline and require mitigation and/or best management practices as appropriate. Emergency Situations: In emergency situations, this NWP may be used to authorize maintenance activities in flood control facilities for which no maintenance baseline has been approved. Emergency situations are those which would result in an unacceptable hazard to life, a significant lose of property, or an immediate, unforeseen, and significant economic hardship If action is not taken before a maintenance baseline ca:; be approved. In such situations, the determination of mitigation requirements, if any, may be deferred until the emergency has been resolved. Once the emergency has ended, a maintenance baseline most be established expeditiously, and mitigation, including mitigation for maintenance conducted during the emergency, must be required am appropriate. Notification: The permittee most submit a pre -construction notification to the district engineer before any maintenance work is conducted (sea general. condition 32). The Pre - construction notification may be for activity -specific maintenance or for maintenance of the entire flood control facility by submitting a five-year (or less) maintenance plan. The Pre - construction notification must include a description of the maintenance baseline and the disposal site for dredged or excavated material. (Authorities; Sections 10 and 904) Note: If the maintenance baseline was approved by the district engineer under a prior version of NWP 31, and the district engineer imposed the one-time, compensatory mitigation requirement on maintenance for a specific reach of a flood control project authorized by that prior version of NWP 31, during the period this version of NWP 31 is in effect (March 19, 2011, to March la, 2022) the district engineer will not require additional compensatory mitigation for maintenance activities authorized by this NWP In that specific reach of the flood control project. 32. completed mforoament Actions.

This, NWP authorizea discharges of dredged or fill material, including dredging or excavation, into all waters of the United States for activities associated with the restoration of upland areas damaged by storms, floods, or other discrete events. This NWP authorizes bank stabilization to protect the restored uplands. The restoration of the damaged areae, including any bank stabilization, must not exceed the contours, or ordinary high water mark, that existed before the damage occurred. The district engineer retains the right to determine the extent of the pre-exiating conditions and the extent of any restoration work authorized by this NWP. The work must commence, or be under contract to commence, within two years of the date of damage, unless this condition is waived in writing by the district engineer. Thin NWP cannot be used to reclaim lands loot to normal erosion processes over an extended period, This NWP does not authorize beach restoration or nourishment. Minor dredging is limited to the amount necessary to restore the damaged upland area and should not significantly alter the pre-existing bottom contours of the waterbody. Notification: The permittee must submit a pre -construction notification to the district engineer (see general condition 32) within 12 months of the date of the damage; for major storms, floods, or other discrete events, the district engineer may waive the 12 -month limit for submitting a pre -construction notification if the permittee can demonstrate funding, contract, or other similar delays. The pre -construction notification must include documentation, such as a recent topographic survey or photographs, to justify the extent of the proposed restoration. (Authority: Sections 1.0 and 404) Noter The uplands themselves that are lost as a result of a storm, flood, or other discrete event can be replaced without a section 404 permit, if the uplands are restored to the ordinary high water mark (in non -tidal waters) or high tide line (in tidal waters].

The discharge moat not cause the loss of greater than 1�2-acre of waters of the United States, including the loss of more than 300 linear feet of. stream bed, unless for intermittent: and Ohemeral stream beds the district engineer waives the 300 linear foot limit by making a written determination concluding that the discharge will result in no more than minimal adverse environmental affects. The loss of stream bed plus any other losses of jurisdictional wetlands and waters caused by the NWP activity cannot exceed 112 -acre. Tae placement of a transmission line on the bed of a navigable water of the United States from the renewable energy generation units) to a land -basad collection and distribution facility is considered a structure under Section 10 of the Rivers and Harbors Act of 7.899 (see 33 CFR 322.2(b)), and the placement of the transmission line on the bed of a navigable water of the United States .is not a loss of waters of the United States for the purposes of applying the 1,2 - acre or 300 linear foot limits. For each single and complete project, no more than 10 generation units (e,g „ wind turbines, wave energy devices, or isydrokinetic devices) are authorized. For floating solar panels in navigable waters of the united States, each single and complete project cannot exceed 1�2-acre in water surface area covered by the floating solar panels. This NWP does not authorize activities in coral reefs. Structures in an anchorage area established by the U.S. Coast Guard must comply with the requirements in 33 CFR 322.511)(2).

Completion of the pilot project will be identified as the date of expiration of the Federal Energy Regulatory Commission (FERC) license, or the expiration data of the NWP authorization if no FERC license is required. Notification: The parmittee must submit a pro -construction notification to the district engineer prior to commencing the activity, (See general condition 32.) (Authorities: Sections 10 and 404) Note 1: Utility lines constructed to transfer the energy from the land-based collection facility to a diatribution system, regional grid, or other facility are generally conaidered to be linear projects and each separate and distant crossing of a waterbody is eligible for treatment as a separate single and complete linear project. Those utility lines may be authorized by NWP 12 or. another Department of the Army authorization, Note 2: An activity that is located on an existing locally or federally maintained U.S. Army Corps of Engineers project requires separate approval from the Chief of Engineers or District Engineer under 33 U.S.C. 408. 17 Nota 3: If the pilot project generation units, including any transmission lines, are placed in navigable waters of the United states (i.e., section 10 waters) within the coastal United States, the Great Lakes, and United states territories, copies of the NNP verification will be sent by the Corps to the National Oceanic and Atmospheric Administration, National ocean Service, for charting the generation units and associated transmission line(s) to protect navigation. Note 4: Hydrokinetic renewable energy generation projects that require authorization by the Federal Rnergy Regulatory Commission under the Federal Power Act of 1920 do not require separate authorization from the Corps under section 30 of the Rivers and Harbors Act of 1099. Note 5: For any activity that involves the construction of a wind energy generating structure, solar tower, or overhead transmission line, a copy of the PCN and NWP verification will be provided to the Department of Defense siting Clearinghouse, which will evaluate potential effects on military activities. 53. Removal of Low -Read Dams.Structurea and work in navigable waters of the United States and discharges of dredged or fill material into waters of the United States associated with the removal of low -head dams. For the purpoaea of this NNP, the term " low -head dam" is defined as a dam built across a stream to pass flows from upstream over all, or nearly all., of the width of the dam crest on a continual. and uncontroll.ed basis. (During a drought, there might not be water flowing over the dam creat.) In general, a low -head dam does not have a separate spillway or spillway gates but it may have an uncontrolled spillway. The dam crest is the top of the dam from left abutment to right abutment, and if present, an uncontrolled spillway. A low -bead dam provides little storage function. The removed low -head dam structure must be deposited and retained in an area that has no waters of the United States unless otherwise specifically approved by the district engineer under separate authorization. Because the removal of the low -head dam will .result in a net increase in ecological functions and services provided by the stream, as a general rule compensatory mitigation is not required for activities authorized by this NWP. However, the district engineer may determine for a particular low -head dam removal activity that compensatory mitigation is necessary to ensure the authorized activity results in no more than minimal adverse environmental effects. Notification: The permittee must submit a pre -construction notification to the district engineer prior to commencing the activity. (Sae general condition 37.) -7 (Authorities: Sections 10 and 404) o Note: This NNP done not authorize discharges of dredged or fill material into waters of the United states or Structures or work in navigable waters to restore the stream in t)ie vicinity of the low -head dam, including the former impoundment area, .Nati.onwidd permit:27 cc-. other Department of the Army permits may authorize such activities. This NWP does' noFJ authorize discharges of dredged or fill material into waters of the United States -nor �'J structures or work in navigable waters to stabilize stream banks. Bank stabilization. _ ;7 activities may be authorized by NNP 13 or other Department of the Army permits. i $4. Living Shorelines. Structures and work in navigable waters of the Unitod States-snd CJ discharges of dredged or fill material into waters of the United States for the cometl tion and maintenance of living shorelines to stabilize banks and shores in coastal waters, �ich includes the Great Lakes, along shores with small fetch and gentle slopes that are subj ct to low- to mid -anergy waves. A living shoreline has a footprint that is made up mostly of native material. It incorporates vegetation or other living, natural •`acEt " elements alone or in combination with some type of harder shoreline structure (e.g., oyster or mussel reefs or rock sills) for added protection and Stability. Living shorelines Should maintain the natural continuity of the land -water interface, and retain or enhance shoreline ecological processes. Living Shorelines must have a substantial biological component, either tidal or lacustrine fringe wetlands or oyster or mussel reef Structures. The following conditions must be met: (a) The structures and fill area, including sand fillo, sills, breakwaters, or reefs, cannot extend into the waterbody more than 30 feet from the mean low water line in tidal waters or the ordinary high water mark in the Great Lakes, unless the district engineer waives this criterion by making a written determination concluding that the activity will result in no more than minimal adverse environmental effects; (b) The activity is no mora than 500 feet in length along the bank, unless the district engineer waives this criterion by making a written determination concluding that the activity will result in no more than minimal adverse environmental effects; (c) Coir logs, coir mats, atone, native oyster shell, native wood debris, and other structural materials must be adequately anchored, of Sufficient weight, or installed in a manner that prevents relocation in most wave action or water flow conditions, except for extremely severe storms; (d) For living shorelines consisting of tidal or lacustrine fringe wetlands, native planta appropriate for current site conditions, including salinity, must be used if the site is plsnted by the parmittee; (a) Discharges of dredged or fill material into waters of the United States, and oyster or mussel reef structures in navigable waters, must be the minimum necessary for the establiaim:ent and maintenance of the living shoreline; (f) If sills, breakwaters, or other structures must be constructed to protect fringe wetlands for the living shoreline, those structures must be the minimum size necessary to protect those fringe wetlands; (g) The activity must be designed, constructed, and maintained no that it has no more than minimal adverse effects on water movement between the waterbody and the shore and the movement of aquatic organisms between the waterbody and the shore; and (h) The living shoreline must be properly maintained, which may require periodic repair of sills, breakwaters, or reefs, or replacing sand fills after severe is atoms or erosion events. Vegetation may be replanted to maintain the living shoreline. This NWP authorizes those maintenance and repair activities, including any minor deviations necessary to address changing environmental conditions. This NWP does not authorize beach nourishment or land reclamation activities. Notification; The permittee most submit a pro -construction notification to the district engineer prior to commencing the construction of the living shoreline. (See general condition 32.) The pre-conatruction notification must include a delineation of special aquatic sites (see paragraph {b)(4) of general condition 32), ere -construction notification in not required for maintenance and repair activities for living shorelines unless required by applicable NIIP general conditions or regional conditions. (Authorities: Sections 10 and 404) Note: In waters outside of coastal waters, nature -based bank stabilization techniques, such as bicengihsering and vegetative stabilization, may be authorized by NWP 13. C. Nationwide Permit General Conditions To qualify for NWP authorization, the prospective permittee must comply with the followirxt general conditions, as applicable, in addition to any regional or cape -specific conditiva� .-- imposed by the division engineer or district engineer. Prospective permittees should contrast th' appropriate Corps district office to determine if regional conditions have been imposed on an NWP. Prospective permittees should also contact the appropriate Corps district office to i( determine the status of Clean Water Act Section 401 water quality certification and/or Coastal t-1 Zone Management Act consistency for an NWP. Every person who nay wish to obtain permit -- authorization under one or more NWP¢, or who is currently relying on an existing or prior permit authorization under one or more NWPs, has been and is on notice that all Of the provisions -of 33 CFR330.1 through 330.6 apply to every NWP authorization. Note especially 33 CPA 330.5 relating to the modification, suapenaion, or revocation of any NNP authorization. 1. Navigation. (a) No activity may cause more than a minimal adverse effect on navigation. (b) Any safety lights and signals prescribed by the O.S. Coast Guard, through regulations or otherwise, must be installed and maintained at the permittee's expense on authorized facilities in navigable waters of the United States. (cl The permittee understands and agrees that, if future operations by the united states require the removal, relocation, or other alteration, of the structure or work herein authorized, or if, in the opinion of the Secretary of the Army or his authorized representative, said structure or work shall cause unreasonable obstruction to the free navigation of the navigable waters, the permittee will be required, upon due notice from the Corps of Engineers, to remove, relocate, or alter the structural work or obstructions caused thereby, without expense to the United states. No claim shall be made against the United States on account of any such removal or alteration. 2. Aquatic Life Movements. No activity my substantially disrupt the necessary life cycle movements of those species of aquatic life indigenous to the waterbody, including those species that normally migrate through the area, unless the activity's primary purpose is to Impound water. All permanent and temporary crossings of waterbodies shall be suitably culverted, bridged, am otherwise designed and constructed to maintain low flown to sustain .the movement of those aquatic species. if a bottomless culvert cannot be used, then the Grossing should be designed and constructed to minimize adverse effects to aquatic life movements. 3. spawning Areas. Activities in spawning areas during spawning seasons must be avoided Co the maximum extent practicable. Activities that result in the physical destruction (e.g., through excavation, fill, or downstream Bmothering by substantial turbidity) of an important spawning area are not authorized. 4. Migratory Bird Breading Areas. Activities in waters of the united States that serve as breeding areas for migratory birds most be avoided to the maximum extent practicable. 5. Shellfish Beds.

Suitable Material. No activity may use unsuitable material (e.g_ trash, debris, car hodies, asphalt, etc.). Material used for construction or discharged must be free from toxic pollutants in toxic amounts (see section 307 of the Clean Water Act). 7, Water Supply Intakes. No activity may occur in the proximity of a public water supply intake, except where the activity is for the repair or improvement of public water supply intake structures or adjacent bank stabilization. e. Adverse Effects from impoundments. if the activity creates an impoundment of water, adverse effects to the aquatic system due to accelerating the passage of water, and/or restricting .its flow most be minimized to the maximum extent practicable. 9. Mauagement of Water. Flows. To the maximum extent practicable, the pre -construction course, condition, capacity, and location of open waters must be maintained for each activity, including stream channelization, storm water management activities, and. temporary and permanent mad crossings, except as provided below. The activity must be constructed to withstand expected high flows. The activity must not restrict or impede the passage of normal or high flown, unless the primary purpose of the activity is to impound water or manage high flows. The activity may altar the pre -construction course, condition, capacity, and location of open waters if it benefits the aquatic environment .(e.g., stream restoration or relocation activities). 10. Fills Within. 100 -Year Floodplain. The activity must comply with applicable FEMA -approved state or local floodplain management requirements. 11. Equipment. Heavy equipment working in wetlands or mudflats most 1•e placed on mats, or other measures must be taken to minimize soil disturbance, 12. soil Erosion and Sediment Controls. Appropriate soil erosion and sediment controls must be used and maintained in effective operating condition during construction, and all exposed soil and other fills, as well as any work below the ordinary high water mark or high tide line, must he permanently stabilized at the earliest practicable date. Permittees are 19 encouraged to perform work within waters of the United States during periods of low -flow or no -flow, or during low tides. 13. Removal of Temporary Fills. Temporary fills must be removed in their entirety and the affected areae returned to pre -construction elevations. -rne affected areas met be revegetated, as appropriate. 14. Proper Maintenance.

Single and Complete Project. The activity must be a single and complete project. The same NNP cannot be used more than once for the same single and complete project. 16. Wild and Scenic Rivers. (a) No NWP activity may occur in a component- of the National Wild and Scenic River System, or in a rive..r officially designated by Congress as a " Study river" for possible inclusion in the system while the river is in as official study status, unless the appropriate Federal agency with direct management responsibility for such river, has determined in writing that the proposed activity will not adversely affect the Wild and Scania River designation or study status. (b) If a proposed NWP activity will occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a " atudy river" for possible inclusion in the system while the river is in an official study status the permittee must submit a pre -construction notification (see general condition 3A. The district engineer will coordinate the PCN with the Federal agency with direct go)lagement responsibility for that river. The permittee shall not begin the NWP activity until notified by the district engineer that the Federal agency with direct management; responsibility for that river has determined in writing that the proposed PPP aciivitl__= will not adversely affect the Wild and Scenic River designation or study__atatue. l � (c) Information on Wild and Scenic Rivers may be obtained from the appropriate Eedera7l lark management agency responsible for the designated wild and Scenic River or study river11I (e.g., National Park Service, U.S. Forest Service, Bureau of Land Management, U.S' Fiah---1 and Wildlife service). information on these rivers is also available at: he tp:J/www. rivers. gov/. 17. Tribal Rights. No NWP activity may cause more than minimal adverse effects on tribal -i ghts (including treaty rights), protected tribal resources, or tribal lands. 18. Endangered Species. (a) No activity is authorized under any NWP which is likely to dirwctly or indirectly jeopardise the continued existence of a threatened or endangered species or a species proposed for ouch designation, as identified under the Federal Endangered Species Act (BSA), or which will directly or indirectly destroy or adversely modify the critical habitat of such species. No activity Is authorized under any NNP which "my affect" a listed species or critical habitat, unless BSA section 7 consultation addressing the effects of the proposed activity has been completed. Direct effects are the immediate affects on listed species and critical habitat caused by the NWP activity. Indirect effects are those effects on listed species and critical habitat that are caused by the NWP activity and are later in time, but still are reasonably certain to occur. (b) Federal agencies should follow their own procedures for, complying with the requirements of the ESA. If pre -construction notification is required for the proposed activity, the Federal permittee must provide the district engineer with the appropriate documentation to demonstrate compliance with those requiramenta.The district engineer will verify that the appropriate documentation has been submitted. If the appropriate documentation has not been submitted, additional ESA section 7 consultation may be necessary for the activity and the respective federal agency would be responsible for fulfilling its obligation under section 7 of the BSA, (c) Non-federal permittees must submit a oro-constnietion notification to the district engineer if any listed species or designated critical habitat might be affected or is in the vicinity of the activity, or if the activity is located in designated critical habitat, and shall not begin wont on the activity until notified by the district engineer that the requirements of the ESA have been satisfied and that the activity is authorized. For activities that might affect Federally -listed endangered or threatened species or designated critical habitat, the pre -construction notification must include the nam(s) of the endangered or threatened species that might be affected by the proposed activity or that utilize the designated critical habitat that might be affected by the proposed activity. The district engineer will determine whether the proposed activity "may of feet" or will have " n, effect" to listed species and designated critical habitat and will notify the non -Federal applicant of the Corps' determination within 45 days of receipt of a complete pre -construction notification. in casae where the non -Federal applicant has identified listed species or critical habitat that might be affected or is in the vicinity of the activity, and has so notified the Corps, the applicant shall not begin work until the Corps has provided notification that the proposed activity will have "no effect" on listed species or critical habitat, or until FSA section 7 consultation has been completed. If the non -Federal applicant has not.. heard back from the Corps within 45 days, the applicant meet still wait for notification from the Corps. Id) As a result of formal or informal consultation with the FWS or NMFS the district engineer may add species-specific permit conditions to the NWPs. (a) Authorization of an activity by an NlgP does not authorize the " take " of a threatened or endangered species as defined under the ESA. In the absence of separate authorization (e.g., an ESA Section 10 Permit, a Biological Opinion with —incidental take" provisions, etc.) from the FWS or the NMFS, the Endangered Species Act prohibits any person subject to the jurisdiction of the United States to take a listed species, where " take " means to harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect, or to attempt to engage in any such conduct. The word "harm" in the definition of " take" means an act which actually kills or injures wildlife. Such an act may include significant- habitat modification or degradation where it actually kills 20 19 20 or injures wildlife by significantly impairing essential behavioral patterns, including breeding, feeding or sheltering. (f) If the non-federal permittee has a valid SSA section 10(a)(1)(B)_.incidental take permit with an approved Habitat Conservation Plan for a project or a group of projects khat includes the propoesd NNP activity, the non-federal applicant should provide a.copy of that MSA Section 10(a)(1)(e) permit with the YIN required by paragraph (c,) of this general condition. The district engineer will coordinate with the agency that issued the y BSA section 10(a)(1)(B) permit to determine whether the proposed NWP activity and, the , associated incidental take were considered in the internal ESA section 7 consultation conducted for the ESA section 10(a)(1)(B) permit, If that coordination results Snu - concurrence from the agency that the proposed NWP activity and the associated inci'denta�l (j take were considered in the internal HSA section 7 consultation for the BSA secti or permit, the district engineer does not need to conduct a separate HSA -.•( section 7 consultation for the proposed NWP activity. The district engineer will notiE}•u J the non-federal applicant within 45 days of receipt of a complete pre-constructioq: notification whether the BSA section 301a)(1)(B)permit covers the proposed NWP activity or whether additional BSA section 7 consultation in required. ,J (g) Information on the location of threatened and endangered species and their critical habitat can be obtained directly from the offices of the PWS and NMFS or their world wide web pages at http:// www fw6.ov or http://www.fwa.gov/ipac and http_:f[Www_nmf s.uoaa.gov rapecies/eaa( respectively - Migratory. Hirds and Bald and Golden Eagles. The pernittea is responsible for ensuring their action complies with the Migratory Bird Treaty Act and the Bald and Golden Hagl.e Protection Act. The permittee is responsible for contacting appropriate local office of the U.S. Fish and Wildlife Service to determine applicable measures to reduce impacts to migratory birds or eagles, including whether "incidental take" permits are necessary and available under the Migratory bird 'treaty Act or Bald and Golden Eagle Protection Act for a particular activity. Historic Properties. (a) In cases where the district engineer determines that the activity may have the potential to cause effects to properties listed, or eligible for listing, in the National Register of Historic Places, the activity is not authorized, until the requirements of Section 106 of the National Historic Preservation Act (NHPA) have been satisfied. (b) Federal permittees should follow their own procedures for complying with the requirements of section 106 of the National Historic Preservation Act. If pre - construction notification is required for the proposed .NWP activity, the Federal permittee must provide the district engineer with the appropriate documentation to demonstrate compliance with those requirements. The district engineer will verify that the appropriate documentation has been submitted. If the appropriate documentation is not submitted, then additional consultation under section 106 may be necessary. 'Elie respective federal agency is responsible for fulfilling its obligation to comply with section 106. (c) Non-federal permittees must submit a pre -construction notification to the district engineer if the NWP activity might have the potential to cause effects to any historic properties listed on, determined to be eligible for listing on, or potentially eligible for listing on the National Register of Historic Places, including previously unidentified properties. For such activities, the pre -construction notification must state which historic properties might have the potential to be affected by the proposed NWP activity or include a vicinity map indicating the location of the historic properties or the potential for the presence of historic properties. Assistance regarding information on the location of, or potential for, the presence of historic properties can be sought from the State Historic Preservation Officer, Tribal Historic Preservation Officer, or designated tribal representative, as appropriate, and the National Regiater of Historic Places (see 33 CFR 330.4(g)). when reviewing pre - construction notifications, district engineers will comply with the current procedures for addressing the requirements of section 106 of the National Historic Preservation Act. The district engineer shall make a reasonable and good faith effort to carry out appropriate identification efforts, which may include background research, consultation, oral history interviews, sample field investigation, and field survey. Based wr the information submitted in the pct and these identification efforts, the district engineer shall determine whether the proposed NWP activity has the potential to cause effects on the historic properties. Section 106 consultation is not required when the district engineer determines that the activity does not have the potential to cause effects on historic properties (see 36 CFR BD0.3(a)). Section 106 consultation is required when the district engineer determines that the activity has the potential to cause effects on historic properties. The district engineer will conduct consultation with consulting parties identified under 36 CFR 500.2(e) when he or she makes any of. the following effect determinations for the purposes of section 106 of the NHPA: no historic properties affected, no adverse affect, or adverse effect. Where the non -Federal applicant has identified historic properties on which the activity might have the potential to cause effects and so notified the Corps, the non -Federal applicant shall not begin the activity until notified by the district engineer either that the activity has no potential to cause effects to historic properties or that NHPA section 106 consultation has been completed. Id) For non-federal permittees, the district engineer will notify the prospective permittee within 45 days of receipt of a complete pre -construction notification whether NHPA section 106 consultation is required. If NHPA section 106 consultation is required, the district engineer will notify the non -Federal applicant that he or she cannot begin the activity until section 106 consultation is completed. If the non -Federal applicant has not heard back from the Corps within 45 days, the applicant must still wait for notification from the Corps. (e) Prospective permittees should be aware that section 110k of the NHPA (54 U.H.C. 306113) prevents the. Corps from granting a permit or other assistance to an applicant who, with 21 21, 22 23 intent to avoid the requiremanta of section 106 of the NHPA, has intentionally significantly adversely affected a historic property to which the permit would relate, or having legal power to prevent it, allowed such significant adverse effect to occur, unless the Corps, after consultation with the Advisory Council on Historic Preservation (ACNP), determinea that circumstances justify granting such assistance despite the adverse effect created or permitted by the applicant. If circumstances justify granting the assistance, the Corps is required to notify the ACHP and provide documentation specifying the circumstances, the degree of damage to the integrity of any historic properties affected, and proposed mitigation. This documentation must include any views obtained from the applicant, SHPO/THPO, appropriate Iridian tribes if the undertaking occurs on or affects historic properties on tribal lands or affects properties of interest to those tribes, and other parties known to have a legitimate interest iai the Impacts to the permitted activity on historic Properties. Discovery of Previously Unknown Remains and Artifacts. If you discover any previously unknown historic, cultural or archeological remains and artifacts while accomplishing the activity authorized by this permit, you must immediately notify the district engineer of what you have found, and to the maximum extent practicable, avoid construction activities that may affect Lhe remains and artifacts until the required coordination has been ' completed. The district engineer will initiate the Federal, Tribal, and state coordi'natigm required to determine if the items or romaine warrant a recovery effort or if the a#e is it eligible for listing in the National Register of Historic Places. Designated Critical Resource Waters, Critical resource waters include, NOAH -managed yarine -� sanctuaries and marine monuments, and National Estuarine Research Reserves. The d.i6.t;ict engineer may designate, after notice and opportunity for public comment, additSoneY waters -- officially designated by a state as having particular environmental or ecological -1 t significance, such as outstanding national resource waters or state natural heritage sites. The district engineer may also designate additional critical resource waters sfter no'jice 1-� and opportunity for public comment. •' (a) Discharges of dredged or fill material into waters of the United States are no" authorized by NNPO 7, 12, 14, 16, 1'7, 21, 29, 31, 35, 39, 40, 42, 43, 44, 49, San, 51, and 52 for any activity within, or'directly affecting, critical. resource waters, including wetlanda adjacent to such waters. (b) For NNPs 3, 8, 10, 13, 15, 18, 19, 22, 23, 25, 27, 28, 30, 33, 34, 36, 37, 38, and 54, notification is required in accordance with general condition 32, for any activity proposed in the designated critical resource waters including wetlands adjacent to those waters. The district engineer may authorize activities under these NW139 only after it is determined that the impacts to the critical resource waters will be no more than minimal. Mitigation. The district engineer will consider the following factors wnon determining appropriate and practicable mitigation necessary to ensure that the individual and cumulative adverse environmental effects are no more than minimal: (a) The activity moat be designed and constructed to avoid and minimize adverse effects, both temporary and permanent., to waters of the United States to the maximum extent practicable at the project site (i.e., on site). (b) Mitigation in all. its forms (avoiding, minimizing, rectifying, reducing, or compensating for resource losses) will be required to the extent necessary to ensure that the individual and cumulative adverse environmental effects are no more than minimal.. (c) Canpansatory mitigation at a minimum one-for-one ratio will be required for allwetland losses that exceed 1,10 -acre and require pre- onstruetion notification, unless the district engineer daterminea in writing that either some other form of mitigation would be more anvironmentally appropriate or the adverse environmental effects of the proposed activity are no more than minimal, and provides an activity -specific waiver of this rnqulrsmont. For wetland losses of 1 -10 -acre or lose that require Pre -construction notification, the district engineer may determine on a rase -by -case basis that compensatory mitigation is required to ensure that the activity results in only minimal adverse environmental effects. (d) Por losses of streams or other open waters Lhat require pre -construction notification, the district engineer may require compensatory mitigation to ensure that the activity results in no more than minimal adverse environmental effects. Compensatory mitigation for losses of streams should be provided, if practicable, through stream rehabilitation, enhancement, or preservation, since streams are difficult -to -replace resources (see 33 CFR 332.3(e)(3)). (e) Compensatory mitigation plans for NWB aetivitisa in or near streams or other open waters will normally include a requirement fox the restoration or enhancement, maintenance, and legal protection (e.g., conservation easements) of riparian areae next to open raters. In some cases, the restoration or maintenance/protection of riparian areas may be the only compensatory mitigation required. Restored riparian areas should consist of native species. The width of the required riparian area will address documented water quality or aquatic habitat loss concerns. Normally, the riparian area will be 25 to 50 feet wide on each side of the stream, but the district engineer may require slightly wider riparian areas, to address dooumarted water quality or habitat loss concerns. If It is not possible to restore or maintain/protect a riparian area on both sides of a stream, or if the waterbody is a lake or coastal waters, then restoring or maintaining/protecting a riparian area along a single bank or shoreline may be sufficient. Where both wetlands and open waters exist on the project site, the district engineer will determine the appropriate compensatory mitigation (e.g., riparian areae and/or watlands compensation) based on what is best for the aquatic environment on a watershed basis. In cases where riparian areas are determined to be the most appropriate form of minimization or compensatory mitigation, the district engineer may waive or reduce the requirement to provide wetland compensatory mitigation for wetland losses. (fl Compensatory mitigation projects provided to offset losses of aquatic resources must comply with the applicable provisions of 33 CFR part 332. 22 24 25. 26 10 28 (1) The prospective permittee is responsible far proposing an appropriate compensatory mitigation option if compensatory mitigation is necessary to ensure that the activity results in no more than minimal adverse environmental effects. For the N"s, the preferred mechanism for providing compensatory mitigation is mitigation bank credits or in -lieu fee program credits lose 33 CFR 332.3(b1(2) and (3)). However, if an.appropriate number said type of mitigation bank or in - lieu credits are not available at the time the PCN in submitted to the district engineer, the district engineer may approve the use of permittee -responsible mitigation. (2) The amount of compensatory mitigation required by the district engineer must be sufficient to ensure that the authorized activity results in no more than minimal individual and cumulative adverse environmental effects (see 33 CFR 330.1(e)(3)). (See also 33 CFR 332.3(f)). (3) Since the likelihood of succaea is greater and the impacts to potentially valuable uplands are reduced, aquatic resource restoration should he the first compensatory mitigation option considered for permittee -responsible mitigation. (4) If panaittee-responsible mitigation is the proposed option, the prospective permittee is responsible for submitting a mitigation plan. A conceptual of detailed mitigation plan may be used by the district engineer to make the, decision on the NWP verification request, but a final mitigation play. that addresses the applicable requirements of 33 CPR 332.4(c)(2) through (14) must be. approved by the district engineer before the parmittee begins work in waters of. the United States, unless the district engineer determines that prior app%val of the final mitigation plan is not practicable or not necessary to ensure '( timely completion of the required compensatory mitigation (see 33 CFR j 1 332.3 (k) (31) . (5) If mitigation Dank or in -lieu fee program credits are the proposed option,,:the mitigation plan only needs to address the baseline conditions at the impdet site and the number of credits to be provided. (6) Compensatory mitigation requirements (e.g., resource type and amount to beo provided as compensatory mitigation, site protection, ecological performance standards, monitoring requirements) may be addressed through conditions added to the NWP authorization, instead of components of a compensatory mitigation plan (see 33 CFR 332.4(C)(1)(ii)). (C) Compensatory mitigation will not be used to increase the acreage Losses allowed by the acreage limit's of the NWPs. For example, if an NWP has an acreage limit of 1�2-acrs, it cannotbe used to authorize any NWP acLiviLy reau3,ting in the loss of greater than 1,2 - acre of waters of the United States, even if compensatory mitigation is provided that replaces or restores some of the lost waters. However, compensatory mitigation can and should be used, as necessary, to ensure that an NWP activity already meeting the established acreage Limits also satisfies the no more than minimal impact requirement for the NWPs. (h) Permitteen may propose the use of mitigation banks, in -Lieu fee programs, or permittee - responsible mitigation. When developing a compensatory mitigation proposal, the permittee must consider appropriate and practicable options consistent with the framework at 33 CFR 332.3(b), For activities resulting in the lose of marine or estuarine resources, permittee -responsible mitigation may be environmentally preferable if there are no mitigation banks or in -lieu fee programs in the area that have marine or estuarine credits available for sale or transfer to the parmittee. For permittee- r.esponsible mitigation, the special conditions of the NWP verification must clearly indicate the party or parties responsible for the implementation and performance of the compensatory mitigation project, and, if required, its long-term management, (.i.) Where certain functions and services of waters of the United States are permanently adversely affected by a regulated activity, such as discharges of dredged or fill material into waters of the United States that will convert a forested or scrub -shrub wetland to a herbaceous wetland in a permanently maintained utility 'line right-of-way, mitigation may be required to reduce the adverse environmental effects of the activity to the no more than minimal level. Safety of impoundment Structures. To ensure that all impoundment structures are safely designed, the district engineer may require non -Federal applicants to demonstrate that the stnicturee comply with established state dam safety criteria or have been designed by qualified persons, The district engineer may also require documentation that the design has been independently reviewed by similarly qualified persons, and appropriate modifications made to ensure safety. - Water Quality. Where States and authorized Tribes, or EPA where applicable, have not previously certified compliance of an NWP with CWA section 401, individual 401 Water Quality Certification must be obtained or waived (see 33 CFR 330.4(c))..The district engineer or State or Tribe may require additional water quality management measures to ensure that the authorized activity does not result in more than minimal degradation of water quality. Coastal Tone Management. In coastal states where an NWP has not previously received a state coastal zone management consistency concurrence, an individual state coastal zone management consistency concurrence must be obtained, or a presumption of concurrence must occur (see 33 CFR 330.4(d)). The district engineer or a State may require additional measures to ensure that the authorized activity is consistent with state coastal zone management requirements, Regional and Case -By -Case Conditions. The activity must comply with any regional conditions that may have been added by the Division Engineer lose 33 CPR 330.4(e)) and with any case specific conditions added by the Corps or by the state, Indian Tribe, or U.S. EPA in its section 401 Nater Quality Certification, or by the state in its Coastal Zone Management Act consistency determination. Use of Multiple Nationwide Permits. The use of more than one NWP for a single and complete project is prohibited, except when the acreage loss of waters of the United States authorized by the NWPs does not exceed the acreage limit of the NNP with the highest specified acreage limit. For example, if a road crooning over tidal waters is constructed 23 under NWP 14, with associated bank stabilization authorized by NWP 13, the maximum acreage loss of waters of the United States for the total project cannot exceed 113 -acre. 29. Transfer of Nationwide Permit Verifications. If the permittee sells the property associated with a nationwide permit verification, the permittee may transfer the nationwide permit verification to the new owner by submitting a letter to the appropriate Corps district office to validate the transfer. A copy of the nationwide permit verification must -be attached to the letter, and the letter must contain the following statement - and signature: When the structures or work authorized by this nationwide permit are still in .existence at the time the property is transferred, the terms and conditions of this nationwide; permit, including any special conditions, will continue to be binding on the new owner�(s) of the property. To validate the transfer of this nationwide permit and the associated 11Sbilitiev, associated with compliance with its teens and Conditions, have the tranaferee-aigh�l�und date below. ----------------------------------------------- (Transferee) -_________ _________________________(Transferee) J ___________ -------------------------------- _---------- _ (Date) 30. Compliance Certification. Each permittee who receives an NWP verification letter from the Corps must provide a signed certification documenting completion of the authorized activity and implementation of any required compensatory mitigation. The success of any required permittee -responsible mitigation, including the achievement of ecological performance standards, will be addressed separately by the district engineer. The Corps will provide the permittee the certification document with the NWP verification letter. The certification document will include: (a) A statement that the authorised activity was done in accordance with the NWP authorization, including any general, regional, or activity -specific conditions; (b) A statement that the implementation of any required compensatory mitigation was completed in accordance with the permit conditions, if credits from a mitigation bank or in -lieu foe program are used to satisfy the compensatory mitigation requirements, the certification must include the documentation required by 33 CPR 332.3(1)(3) to confirm that the permittee secured the appropriate number and resource type o£ credits; and (c) The signature of the permittee certifying the completion of the activity and mitigation.The completed certification document must be submitted to the district engineer within 30 days of completion of the authorized activity or the implementation of any required compensatory mitigation, whichever occurs later. 31. Activities Affecting Structures or Works Built by the United States. If an NWP activity also requires permission from the Corps pursuant to 33 O.S.C. 408 because it will alter or temporarily or permanently occupy or use a V.S. Army Corps at.' Engineers (USACR) federally autharieed Civil Works project (a "USACR Project' '" ), the prospective permittee must submit a pre -construction notification. See paragraph (b)(10) of general condition 32. An activity that requires section 408 permission is not authorized by NWP until the appropriate Corps office issues the section 400 permission to alter, occupy, or use the USACR project, and the district engineer issues a written NWP verification. 32, Pre -Construction Notification. (a) Timing. Where required by the terms o£ the NWP, the prospective permittee must notify the district engineer by submitting a pre -construction notification (PCN) as early as possible. The district engineer must determine it the PCN is complete within 30 calendar days of the date of receipt: and, if the PCN is determined to be Incomplete, notify the prospective permittee within that 30 day period to request the additional information necessary to make the PCN complete. The request must specify the information needed to make the PCW complete. As a general rule, district engineers will request additional information necessary to make the PCN complel:e only once. However, if the prospective permittee does not provide all of the requested information, than the district engineer will notify the prospective permittee that the PCN in still incomplete and the PCN review process will not commence until all of the requested information has been received by the district engineer. The prospective pormittee shall not begin the activity until either: (1) Be or she is notified in writing by the district engineer that the activity may proceed under the NWP with any special conditions imposed by the district or division engineer; or (2) 45 calendar days have passed from the district engineer's receipt of the complete PCN and the prospective permittee has not received written notice from the district or division engineer. However, if the permittee was required to notify the Corps pursuant to general condition 18 that listed species or critical habitat might be affected or are in the vicinity of the activity, or to notify the Corps pursuant to general condition 20 that the activity might have the potential to cause effects to historic properties, the permittee cannot begin the activity until receiving written notification from the Corps that there is "no affect" on listed species or " no potential to cause effects" on historic properties, or that any consultation required under Section 7 of the hndangerad Species Act (see 33 CFR 330.4(f)) and/or section 106 of the National Historic Preservation Act (see 33 CPR 330.419)) has been completed. Also, work cannot begin under MPs 21, 49, or 50 until the permittee has received written approval from the Corps. if the proposed activity requires a written waiver to exceed specified limits of an NWP, the permittee may not begin the activity until the district engineer issues the waiver. If the district or division engineer notifies the permittee in writing that an individual permit is required within 45 calendar days of receipt of a complete PCN, the permittee cannot begin the activity until an individual permit has been obtained. Subsequently, the permittee's right to proceed under the NWP may be modified, suspended, or revoked only in accordance with the procedure net forth in 33 CPR 330.5(d)(2). 24 (b) Contents of Pre -Construction Notification; The PCN must be in writing and include the following information: (1) Name, address and telephone numbers of the prospective permittee; (2) location of the proposed activity; (3) Identify the specific NWP or NWP(s) the prospective permittee wants to use to authorize the proposed activity; (4) A description of the proposed activity; the activity's purpoae; direct and indirect adverse environmental effects the activity would cause, including the anticipated amount of loss of wetlands, other special aquatic sites, and other waters expected to result; from the NWP activity, in acres, linear feet, or other appropriate unit of measure; a description of any proposed mitigation measures intended to reduce the adverse environmental effects caused by the proposed activity; and any other NWP(m), regional general permit(s), or individual permits) used or .intended to be used to authorize any part of the proposed project or any related activity, including other Separate and distant crossings for linear projects that require Department of the Army authorization but do not require pre -construction notification. The description of the proposed activity and any proposed mitigation measures should be Sufficiently detailed to allow the district engineer to determine that the adverse environmental. effects of the activity will be no more than minimal and to determine the need for compensatory mitigation or other mitigation measures. For single and complete linear projects, the PCN must include the quantity of anticipated losses Of wetlands, other special aquatic sites, and other waters for each single and complete crossing of those wetlands, other special aquatic sites, and other waters. Sketches should be provided when necessary to Show, that the activity complies with the terns of the NWP. (Sketches usually clarify the activity and when provided results in a quicker. decision. Sketches should contain suffictint detail to provide an illustrative description of the proposed activityEtI.g., a conceptual plan), but do not need to be detailed engineering plans); .," (5) The PCM must include a delineation of wetlands, other special aquatic jites, $ivi other waters, much as lakes and ponds, and perennial, intermittent, -,and ephemeral streams, on the project site. Wetland delineations mustbe pre aced -j. accordance with the currant method required by the Corps. The permitte�ay a#k the Corps to delineate the Special aquatic Sites and other waters ch the prof site, but there may be a delay if the Corps does the delineation,, e0peoially 4fi the project site is large or contains many wetlands, other special aquatic sites, and other waters. Furthermore, the 45 day period will not start until Zo delineation has been submitted to or completed by the Corps, as appioprTate; (6) If the proposed activity will result. in the loss of greater Lhan 1,10 -acre of wetlands and a PCN .is required, the prospective permittee must submit a,0 statement describing how the mitigation requirement will be satisfied, or explaining why the adverse environmental effects are no more than minimal and why compensatory mitigation should not be required. AD an alternative, the prospective permittee may submit a conceptual or, detailed mitigation plan, (7) For non-Pedaral permittees, if any listed species or designated critical habitat might be affected or in in the vicinity of the activity, or if the activity is located in designated critical habitat, the PCN must include the names) of those endangered or threatened species that might be affected by the proposed activity or utilise the designated critical habitat that might be affected by the proposed activity. For NWP activities that require pre -construction notification, Federal permittees must provide documentation demonatratirg compliance with the Endangered Species Act; (8) For non Federal permittees, if the NWP activity might have the potential to cause effects to a historic property listed on, determined to be eligible for listing on, or potentially eligible for listing On, the National Register of Historic Places, the PCN must state which historic property might have the potential to be affected by the proposed activity or include a vicinity map indicating the location of the historic property. For NWP activities that require pre -construction notification, Federal permittees must provide documentation demonstrating compliance with section 106 of the National Historic Preservation Act; (9) For an activity that will occur in a component of the National Wild and Scenic River System, or in a river officially designated by Congress as a "study river" for possible inclusion in the system while the river is in an official study Status, the PCN must identify the Wild and Scenic River or the " study river" (see general condition 16); and (10) For an activity that requires permission from the Corps pursuant to 3.3 U.S.C. 408 because it will alter or temporarily or permanently occupy or use a D,s, Army Corps of Engineers federally authorized civil works project, the pre - construction notification must include a Statement confirming that the project proponent has submitted a written request for section 400 permission from the Corps office having jurisdiction over that USACE project. (c) Form of Pre -Construction Notification: The standard individual permit application form (Form SNO 4345) may be used, but the completed application form must clearly indicate that it is an NWP PCN and must include all of the applicable information required in paragzapha (b)(1) through (10) of this general condition. A letter containing the required information may also be used. Applicants may provide electronic files of PCNs and Supporting materials if the district engineer has established tools and procedures for electronic submittals. (d) Agency Coordination: (1) The district engineer will consider any comments from Federal and state agencies concerning the proposed activity's compliance with the Lexis and conditions of the NWPe and the need for mitigation to reduce the activity's adverse environmental effects so that they are an more than minimal. 25 9Z Aug a9pTS000 TITM x30uT5uB 10TalttP aqy '(9um alg " 6•a) sxalem ;o saclAq aoglo of egoedwT ao;

The compensatory mitigation proposal may be either conceptual or detailed. if the district engineer determines that the activity complies with the terms and conditions of the NNP and that the adverse environmental effects are no more than minimal, after considering mitigation, the district engineer will notify the permittee and include any activity - specific conditions in the NNP verification the district engineer deems necessary. Conditions for compensatory mitigation requirements must comply with the appropriate provisions at 33 CFR 332.3(k). The district engineer must approve the final mitigation plan before the permittee commences work in waters of the United States, unless the district engineer determines that prior approval of the final mitigation plan is not practicable or not necessary to ensure timely completion of the required compensatory mitigation. If the prospective permittee elects to submit a compensatory mitigation plan with the PCW, the district engineer will expeditiously review the proposed compensatory mitigation plan. The district engineer must review the proposed compensatory mitigation plan within 45 calendar days of receiving a complete PCN and determine whether the proposed mitigation would ensure the NWP activity results in no more than minimal advetso environmental effects. rf the net adverse environmental effects of the NWP activity (after consideration of the mitigation proposal) are determined by the district engineer to be no more than minimal, the district engineer will provide a timely written response to the applicant. The response will state that the NWP activity can proceed under the terms and conditions of the NWP, including any activity -specific conditions added to the NwP authorization by the district engineer. 4. If the district engineer determines that the adverse environmental effects of the proposed activity are more than minimal, than the district engineer will notify the applicant either: (a) That the activity does not qualify for authorization under the NWP and instruct the applicant on the procedures to seek authorization under an individual permit; (b) that the activity in authorized under the NWP subject to the applicant's submission of a mitigation plan that would reduce the adverse environmental effects no that they are no more than minimal; or (c) that the activity is authorized under. the NWP with specific modifications or conditions. where the district engineer determine that mitigation is required to ensure no more than minimal adverse environmental effects, the activity will be authorized within the 45 -day PCN period (unless additional time is required to comply with general conditions 10, 20, and/or 31, or to evaluate PCNa for activities authorized by NWPe 21, 45, and 50), with activity -specific conditions that state the mitigation requirements. The authorization will include the necessary conceptual or detailed mitigation plan or a requirement that the applicant submit a mitigation pian that would reduce the adverse environmental effects so that they are no more than minimal. When compensatory mitigation is required, no work in waters of the United states may occur until the district engineer has approved a specific mitigation plan or has determined that prior approval of a final mitigation plan is not practicalble or not necessary to ensure timely completion of the required compensatory mitigation. 2. Further Information 1. District Engineers have authority to determine if as activity complies with the tnYm6h-A'nd conditions of an NWP. J 2. NWPs do not obviate the need to obtain other federal, state, or local permits, approvals, or authorizations required by law. - ,.`� 3. NWPa do not grant any property rights or exclusive privileges.' „T 4. NWPs do not authorize any injury to the property or rights of others. N 5. NWPa do not authorize interference with any existing or proposed Federal projeotl(sis,e et'ai_ Condition 32). - - F. Definitions -' -- t Beat management practices (SMPs): Policies, tractions, procedures, or structures implemepted to mitigate the adverea environmental effects on surface water quality resulting from deve}9pment. BMPa are categorized as structural or non-structural. Compensatory mitigation: The restoration (to -establishment or rehabilitat.ion), establishment (creation), enhancement, and/or in certain circumstances preservation of aquatic resources for the purposes of offsetting unavoidable adverse impacts which remain after all appropriato and practicable avoidance and minimization has been achieved. Currently serviceable: Useable as is or with some maintenance, but not no degraded as to essentially require reconstniction. Direct effects: Effects that are caused by the activity and occur at the same time and place. Discharge: The term "discharge' ''' means any discharge of dredged or fill material into waters of the United States. Ecological reference: A model used to plan and design an aquatic habitat and riparian area restoration, enhancement, or establishment activity under NWP 27. An ecological reference may be based on the struCture, functions, and dynamics of an aquatic habitat type or a riparian area type that currently exists in the region where the proposed NWP 27 activity is located. Alternatively, an ecological reference may be based on a conceptual model for the aquatic habitat type or riparian area type to be restored, enhanced, or established an a result of the proposed NWP 27 activity. An ecological reference takes into account the range of variation of the aquatic habitat type or riparian area type in the region. Enhancement: The manipulation of the physical, chemical, or biological characteristics of an aquatic resource to heighten, intensify, or improve a specific aquatic resource hmction(a). 27 Enhancement results in the gain of selected aquatic resource function (a), but may also .lead to a decline in other aquatic resource function(s). Enhancement does not result 41 a gain in._aquatic. 1 resource area. Ephemeral stream: An ephemeral stream has flowing water only daring, and for a aIh=t'du>Aion after, precipitation events In a typical year. Ephemeral stream beds are located.4"e. rah water- table atertable year-round, Groundwater is not a source of water for the stream. Runoff from'rainfgij is i 1 the primary source of water for stream flow. Establishment (creation): The manipulation of the physical, chemical, or biological characteristics present to develop an aquatic resource that did not• previously exist at aq.ypland site. Establishment results in a gain in aquatic resource area. !J High Tide Lines The line of intersection of the land with the water's surface at the maximum height reached by a rising tide. The high tide line may be determined, in the absence of actual data, by a line of oil or soon along shore objects, a more or lees continuous deposit of fine shell or debris on the foreshore or berm, other physical markings or characteristics, vegetation lines, tidal gages, or other suitable means that delineate the general height reached by a rising tide. The line encompasses spring high tides and other high tides that occur with periodic frequency but does not include storm surges in which there is a departure from the normal or predicted reach of the tide due to the piling up of water against a coast by strong winds such as those accompanying a hurricane or other intense storm. Historic property: Any prehistoric or historic district, site (including archaeological site), building, structure, or other object included in, or eligible for inclusion in, the National Register of Historic Places maintained by the Secretary of the Interior. This term includes artifacts, records, and remains that are related to and located within such properties. The term includes properties of traditional religious and cultural importance to an Indian tribe or Native Hawaiian organization and that meet the National Register criteria (36 CFR part 60). Independent utility: A test to determine WhaL constitutes a single and complete non-linear project in the Corps Regulatory Program. A project is considered to have independent utility if it would be constructed absent the construction of. other projects in the project area. Portions of a multi-phase project that depend upor. other phases of the project do not have independent utility. Phases of a project that would be constructed even if the other phases were not built can be considered as separate single and complete projects with independent utility. Indirect effects: Effects that are caused by the activity and are later in time or farther removed in distance, but are still reasonably foreseeable. Intermittent stream: An intermittent stream has flowing water during certain times of the year, when groundwater provides water for etream flow. During dry periods, intermittent streams may rot have flowing water. Rwiof£ from rainfall is a supplemental source of water for stream flow. Losa of waters of the United States: Waters of the United States that are permanently adversely affected by filling, flooding, excavation, or drainage because of the regulated activity. Permanent adverse effects include permanent discharges of dredged or fill material that change an aquatic area to dry land, increase the bottom elevation of a waterbody, or change the use of a waterbody. The acreage of lose of waters of the United States is a threshold measurement of the impact to jurisdictional waters for determining whether a project may qualify for an NWP; it is not a net threshold that is calculated after considering compensatory mitigation that may be used to offset losses of aquatic functions and services. The loss of stream bed includes the acres or Linear feet of stream bed that are filled or excavated an a result of the regulated activity. Waters of the United States temporarily filled, flooded, excavated, or drained, but restored to pre-construction contours and elevations after construction, are not included in the measurement of loss of waters of the United States. Impacts resulting from activities that do not require Department of the A=my authorization, such as activities eligible for exemptions under section 409(f) of the Clean Water Act, are not considered when calculating the loss of waters of the United States. Navigable waters: waters subject to Section 10 of the Rivera and Harbors Act of 1699. These waters are defined at 33 CFR part 329. Non-tidal wetland: A non-tidal wetland in a wetland that is not subject to the ebb and flow of tidal waters. Non-Iridal wetlands contiguous to tidal waters are located landward of the high tide line (i.e., spring high tide Sine). Open water.: For purposes of the NWPs, an open water is any area that in a year with normal patterns of precipitation has water flowing or standing above ground to the extent that an ordinary high water mark can be determined. Aquatic vegetation within the area of flowing or standing water is either non-emergent, spares, or absant. Vegetated shallows are considered to be. open waters. Examples of —open waters'' include rivers, streams, lakes, and ponds. Ordinary High Water Mark: An ordinary high water mark is a line on the shore established by the fluctuations of water and indicated by physical characteristics, or by other appropriate means that consider the characteristics of, the surrounding areas. Perennial stream: A perennial stream has flowing water year-round during a typical year. The water table is located above the stream bed for most of the year. Groundwater in the primary source of water for stream flow. Runoff from rainfall is a supplemental source of water for stream flow. 28 Practicable: Available and capable of being done after taking into consideration cost, existing technology, and logistics in light of overall project purposes. Pre -construction notification: A request submitted by the project proponent to the Corps for confirmation that a particular activity is authorized by nationwide permit. The request maybe a permit application, letter, or similar document that includes information about the proposed work and its anticipated environmental effects. Pre -construction notification may be required by the torma and conditions of a nationwide permit, or by regional conditions. A pre -construction notification may be voluntarily submitted in cases where pre -construction notification is not required and the project proponent wants confirmation that the activity is authorized by nationwide permit. Preservation: The removal of a threat to, or preventing the decline of, aquatic resources by an action in or near those aquatic resources. This term includes activities commonly associated with the protection and maintenance of aquatic resources through the implementation of appropriate legal and physical mechanisms. Preservation does not result in a gain of aquatic resource area or functions. Protected tribal resources: Those natural resources and properties of traditional or customary religious or cultural importance, either on or off, Indian lands, retained by, or reserved by or for, Indian tribes through treaties, statutes, judicial decisions, or executive orders, including tribal trust resources. Re-establishment: The manipulation of the physical, chemical, or biological characcoristica of a site with the goal of returning natural/hintarid functions to a former aquatic resource. Re- establishment results in rebuilding a former aquatic resource and results in a gain in aquatic resource area and functions. Rehabilitation: The manipulation of the physical, chemical., or biological characteristics or a site with the goal of repairing natural/historic functions to a degraded aquatic resource. Rehabilitation results in a gain in aquatic resource function, but does not result in a gain aquatic resource area. Restoration; The manipulation of the physical., chemical, or biological characteristics of a site with the goal of returning natural/historic functions to a former or degraded aquatic resource. For the purpose of tracking net gains in aquatic resource area, restoration is divided in two categories: Re-establishment and .rehabilitation. -' Riffle and pool complex: Riffle and pool complexes are special aquatic sites under the IOt(b)(1) Guidelines, Riffle and pool complexes sometimea characterize steep gradient sections- of st'r'eams.' Such stream sections are recognizable by their hydraulic characteristics. The rapid movement of water over a course substrate in riffles results in a rough flow, a turbulent surface, slid high dissolved oxygen levels in the water, Pools are deeper areas associated with riffles.' A 'slower stream velocity, a streaming flow, a smooth surface, and a finer substrate characterize pocic. i Ripar$.an areas: Riparian areas are lands next to streams, lakes, and estuarine -marine shorelines. `� Riparian areae are transitional between terrestrial and aquatic ecosystems, througb which.surface and subsurface hydrology connects riverine, lacustrine, estuarine, and marine waters with thoir adjacent wetlands, non -wetland waters, or uplands. Riparian areas provide a variety of ecalcgical functions and services and help improve or maintain local water quality. (See general condition 23.) shellfish seeding: The placement of shellfish seed and/or suitable substrate to increase shellfish production. Shellfish seed consists of immature individual shellfish or individual shellfish attached to shells or shell fragments (i.e., spat on shell), Suitable substrate may consist of shellfish shslle, shell fragments, or other appropriate materials placed into waters for shellfish habitat. Single and complete linear project: A linear project is a project constructed for the purpose of getting people, goods, or services from a point of origin to a terminal point, which often involves multiple crossings of one or more waterbodiee at separate and distant locations. The term " single and complete project' is defined as that portion of the total linear project proposed or accomplished by one owner/developer or partnership or other association of owners/developers that includes all. crossings of a single water of the United States (i.e., a single waterbody) at a specific location. For linear projects crossing a single or multiple waterbodiee several times at separate and distant locations, each crossing is considered a single and complete project for purposes of NWP authorization. However, :Aldi.vidual channels in a braided stream or river, or individual, arms of a large, irregularly shaped wetland or lake, etc., are not - separate waterbodies, and crossings of such features cannot be considered separately. single and complete non-linear project: For non-linear projects, the term "single and complete project" is defined at 33 CFR 330.21i) as the total project proposed or accomplished by one owner/developer or partnership or other association of owners/developers. A single and complete non-linear project must have independent utility (see definition of " independent utility—). Single and complete non-linear projects may not be " piecemealed " to avoid the limits in an NWP authorization. Stormwater management: Stormwater management is the mechanism for controlling stormwater runoff for the purposes of reducing downstream erosion, water quality degradation, and flooding and mitigating the adverse effects of changes in land use or. the aquatic environment. Stormwater management facilities: Stormwater management facilities are those facilities, including but not limited to, Stormwater retention and detention ponds and best management practices, which retain water for a period of time to control runoff and/or improve the quality 29 (i.e., by reducing the concentration of nutrients, sediments, hazardous substances and other pollutants) of stor. Ater runoff. Stream bed: The substrate of the stream channal between the ordinary high water marks. The substrate may be bedrock or inorganic particles that range in size from clay to boulders, Wetlands contiguous to the stream bad, but outside of the ordinary high water marks, are not considered part of the stream bed. Stream channelization: The manipulation of a stream's course, condition, capacity, or location that causes more than minimal interruption of normal stream processes. A channelized stream remains a water of the United States. Structure: An object that is arranged in a definite pattern of organization. Examples of structures include, without limitation, any pier, boat dock, boat ramp, wharf, dolphin, weir, boom, breakwater, bulkhead, revetment, riprap, jetty, artificial island, artificial reef, permanent mooring structure, power transmission line, permanently moored floating Vessel, piling, aid to navigation, or any other manmade obstacle or obstruction. Tidal wetland: A tidal wetland is a jurisdictional wetland that is inundated by tidal waters. Tidal waters rise and fall in a predictable and measurable rhythm or cycle due to the gravitational pulls of the moon and stuff. Tidal waters and where the rise and fall of the water surface can no longer be practically measured in a predictable rhythm due to masking by other waters, wind, or other effects. Tidal wetlands are located channelward of the high tide line. Tribal lands: Any lands title to which in either: Il) Hold in treat by the united States for the benefit of any Indian tribe or individuals or (2) held by any Indian tribe or individual subject to restrictions by the United States against alienation. Tribal rights: Those rights legally accruing to a tribe or tribes by virtue of inherent sovereign authority, unextinguished aboriginal title, treaty, statute, judicial decisions, executive order or agreement, and that give rise to legally enforceable remedies. Vegetated sinallowa: Vegetated shallows are special aquatic sites under the 404(b)(1) Guidelines. They are areas that are permanently inundated and under normal circumstances have rooted aquatic vegetation, such as seagrasses in marina and estuarine systems and a variety of vascular rooted plants in freshwater systems. Waterbody: For purposes of the NWPs, a waterbody is a jurisdictional water of the United States. If a wetland in adjacent to a waterbody determined to be a water of the United States, that waterbody and any adjacent wetlands are considered together as a single aquatic unit (See 33 CTR 378.4(e)(2)I. Examples of "waterbodies" include streams, rivers, lakes, ponds, and wetlands. PCN - Pre -Construction Notification 30 ru N O Fields of oprorti'ties STATE OF IOWA TERRY E.

The Corps also issued two new NWPs and one new general condition, The NWPs, general conditions, and definitions will be effective on March 19, 2017. In accordance with Section 401 of the Federal Clean Water Act (33 U.S.C. par. 1251 et. seq.), the Iowa Department of Natural Resources has reviewed the proposed modifications and additions to the NWPs and Iowa Regional Conditions and, by this letter, is issuing Section 401 Water Quality Certification with the following conditions: 1. Side slopes of a newly constructed channel will be no steeper than 2:1 and planted to permanent, perennial, native vegetation if not armored. 2. Nationwide permits with mitigation may require recording of the nationwide permit and pertinent drawings with the Registrar of Deeds or other appropriate official charged with the responsibility for maintaining records of title to, or interest in, real property and require the permittee to provide proof of that recording to the Corps. 3. Mitigation shall be scheduled prior to, or concurrent with, the discharge of dredged or fill material into waters of the United States, unless an alternate timeline is specifically approved in the authorization. 4. For newly constructed channels through areas that are unvegetated, native grass filter strips, or a riparian buffer with native trees or shrubs a minimum of 35 feet wide from the top of the bank must be planted along both sides of the new channel. A survival rate of 80 percent of native species shall be achieved within three years of establishment of the buffer strip, 502 EAST 9th STREET/ DEs MOINES; IOWA 50319-0034 PHONE: 515.725.8200 FAX 515-725-8202 www.iowadiir.gov 5. For single-family residences authorized under nationwide permit 29, the permanent loss of waters of the United States (including jurisdictional wetlands) must not exceed 1/4 acre. 6. For nationwide permit 46, the discharge of dredged or fill material Into ditches that would .sever the jurisdiction of an upstream water of the United States from a downstream water of the United States Is not allowed. 7. For projects that impact an Outstanding National Resource Water, Outstanding Iowa Water, fens, bogs, seeps, 'or sedge meadows, a Pre -Construction Notice 1 accordance with General Condition No. 32 and an Individual Section 401 Wate Quality Certiflcation will be required, 8. For nationwide .permits when the Corps' District Engineer has issued a waiver tq allow the permittee to exceed the limits of the nationwide permit, an I41-dividual Section 401 Water Quality Certification will be required: r' 9. Operation of heavy :equipment within the stream.channel should be avoided. If in - stream work Is unavoidable,.. it shall be performed in such a manner as to minimize the duration of the disturbance, turbidity increases, substrate disturbance, bank .disturbance, and disturbance to riparian vegetation. This condition does not further restrict otherwise authorized drainage ditch maintenance activities. 10.Any bank stabilization activity Involving a method that protrudes from the bank contour, such as jetties, stream barbs and/or weirs, will require a Pre - Construction Notice in accordance with General Condition No. 32. 11.Beyond what is described in General Condition # b, suitable fill material shall consist of clean materials, free from debris, trash, and other deleterious materials.

Wash water shall not be discharged into any wetland, waterway, or any other surface water conveyances. For any project that occurs on the Mississippi River, Missouri River, or a Category 4c 303(d) listed water body (attached), the Corps will contact the IDNR (Section 401 Water Quality staff) for project -specific comments/conditions to protect water quality/aquatic resources prior to finalizing the permit decision. Best management practices must be used to prevent and control spills of hazardous substances and if there is a release, it must be reported to the Iowa Department of Natural Resources at 515-725-8694 as soon as possible but not later than 6 hours after the onset or discovery of the hazardous condition. If the hazardous condition involves the release of an EPA regulated material or an oil as defined by the EPA, the release may also need to be reported to the National Response Center at (800) 424-8802. Federal Reporting is required within 15 minutes of event occurrence or discovery. We would like to ask the Corps to encourage applicants to use natural channel design principles and bioengineering techniques when the project involves reconstructing stream channels. This will help restore or enhance the habitat values of the reconstructed stream channel. If you have any questions or comments regarding this Section 401 Water Quality Certification, please contact me at the address shown below or call (515) 725-8399. Sincerely, Christine M.

Box 2004 Rock Island, Illinois 61204-2004 Dear Mr. Shoemaker: This letter completes the Environmental Protection Agency Region 7's consideration of water quality certification for final Corps of Engineers Clean Water Act Section 404 nationwide permits as effective in Indian country. This letter transmits the EPA Region 7's CWA Section 401 water quality certification for Indian country. When the Nationwide Permits are reissued, please let us know that our certification is on your website for viewing by the public. Thank you. The EPA appreciates the Corps coordination during this process. We especially want to thank your district for incorporating our suggested tribal regional condition regarding notification. This will help the Tribes as well as our agency with transparency of the process. We also believe coordination efforts between our agencies and the Tribes will aid in the protection of the environment and publiq:,4eaith. If you have Section 401 matters, please contact Jennifer Ousley of my staff at (913) 5511,7498,1-6r ouslev fifer rhe a v, for assistance. " 1� Enclosure Sincerely, Steve Kov c Chief Watershed Planning and Implementation Branch '" h.j' Nnrod a, Roiydod r,,poi Enclosure U.S. Environmental Protection Agency, Region 7 Clean Water Act Section 401 Water Quality Certification for U.S. Army Corps of Engineers CWA Section 404 Nationwide Permits Reissuftee Location: Projects proposed in .Indian Country within the following Corps Districts as, relevant; ' Kansas City District, Omaha District, and Rock Island District. 1 Indian country includes the following: Iowa Tribe of Kansas and Nebraska, Kitkapbo ' Tribe of Kansas, Omaha Tribe of Nebraska, Prairie Band Potawatomi Nation,k'onca Tribe of Nebraska, Sac and Pox Nation of Missouri in Kansas and Nebraska, Sac and Fox Tribe of the Mississippi in Iowa, Santee Sioux Nation of Nebraska, and Winnebago Tribe of Nebraska Description: NWPs are a type of general permit issued by the COE for discharge (dredge and fill) activities having minimal impacts. For more information on NWPs, go to: http.11www.uszice.army.mil/Missio i Clvil-Works/Re ug latorv=Program and- Perrni is/Nationwide-Permits. Permit Type: Nationwide Permits Reissuance 401 BACMROUND: Section 401 of the CWA requires that an applicant for a federal permit (such as a COE CWA Section 404 NWP) must obtain water quality certification that the discharge will comply with the applicable provisions of the CWA. Activities/projects can be authorized under a NWP only if that activity and the permittee satisfy all of the COE's NWP's terms and conditions, including water quality certification. Presently, the tribes in Region 7 do not have the EPA -approved water quality standards or Section 401 certification programs. In the absence of such certification program, the EPA makes the certification determination. Therefore, this Certification is a condition of the COE CWA Section 404 NWPs as applied within EPA Region i Indian country within each COE District rioted above. DETERMINATION: DENIED: The following activities/projects are denied water quality certification. Therefore applicants must apply for an EPA Region 7 individual water quality certification. Please note: 1) an individual certification involves at least a 60 day process from receipt of a complete certification application and 2) an individual certification may result in additional technical comments/assistance, conditions and/or mitigation requirements. • Any proposed activity/project that requires a pre -construction notice in accordance with NWP General Condition 32 related to a waiver to allow the permittee to exceed the limits of the nationwide permit. • Any proposed activity/project involving the installment of a dam or other type of impoundment. • Any proposed activity/project that impacts a fen, bog, seep or sedge meadow. • Any proposed activity/project under NWP 53 related to removal of low head dams. APPROVED WITH CONDITIONS: All NWPs (or activity authorized under a NWP) not listed as denied above are approved provided they comply with the 401 conditions described below. 401 CONDITIONS: • During project planning, EPA highly recommends the permittee notify the appropriate tribal environmental office of the project details and location. ,-J • Copies of the Corps permit including this certification should be kept on the job site acid readily available to the public for reference. ' • As noted in the NWPs General Condition 23, the project should avoid and miAiha iinpacls to the maximum extent practicable. In addition, EPA highly recommends that projects incQrpor tg ) the following, but not limited to, best protective measures and management practices: o All practicable measures and precautions should be taken to prevent pollution affecting public health, fish, shellfish, wildlife, and recreation due to turbidity, pH, temperature, nutrients, suspended solids, floating debris, visible oil and grease, or other pollutants entering waters of the U.S., including wetlands. o All equipment operated within any water of the U.S. should be cleaned away from waters of the U.S. and maintained to prevent fuel and oil leaks. These methods include, but are not limited to, off-site/upland fuel and oils storage and refueling areas, on-site spill containment equipment, a spill contingency plan, spill prevention/contaminant training for on-site personnel, and spill communication plan. Should a spill of petroleum products or chemicals occur, permittee agrees to immediately call the National Response Center at (800) 424-8802 and the appropriate Tribal Environmental Office. o Any bank stabilization activities should utilize bioengineering techniques (e.g. willow plantings, root wads, large woody debris, etc.) or combination of hard -armoring (e.g. rock) and bioengineering techniques. Ground disturbance should be minimized to that necessary to complete the project. • As noted in the NWPs, native plants appropriate for site conditions must be used for bioengineering or vegetative stabilization. In addition for all types of or phases in projects, EPA highly recommends the following, but not limited to, best management practices: o Native vegetation, especially riparian corridors, should be protected during construction with locations disturbed by construction activities returned to pre -project conditions. This shall include restoration of surface contours, stabilization of the soil, and restoration of appropriate native vegetation lost during construction to establish permanent cover. o Non-native plant species such as reed canary grass (Phalarix arundinacea), Caucasian bluestem (Bothriochloa hladhii), smooth brome (Bronm inermis), crownvetch (Securigera varia), and bird's foot trefoil (Lotto corniculatets) are NOT appropriate as revegetation plantings for erosion control measures, restoration, and/or mitigation. o Measures should be taken to prevent the spread of invasive species. Project locations containing invasive species should be treated using appropriate control methodologies before construction activities begin to reduce the potential for off-site spread. o Clean and certified weed -free seed should be used for vegetative restoration projects. Propagative materials (seeds, plugs, plants, etc.) containing any Federal- or State -listed Noxious Weed and/or Watch List Plant Species should be rejected. o Straw and/or mulch hay used for erosion control measures and/or vegetation restoration should be certified as weed free using the North American Invasive Species Management Association's Weed Free Forage Standard. Please refer to the standard at: http:/lwww.naisma.org/weed-free—forme. If you have questions regarding this certification for COE CWA Section 404 Nationwide Permits or if you need to request an EPA individual water quality certification, contact Jennifer Ousley at the EPA Region 7 at ousley.jennifer rt,epa.gov.

In the event the Jurisdiction incurs any "outlay and expense" in defending itself against any claim as to which the Contractor or Surety should have provided the defense, or in the enforcement of the promises given by the Contractor in the Contract, Contract Documents, or approved change orders, or in the enforcement of the promises given by the Contractor and Surety in this Bond, the Contractor and Surety agree that they will make the Jurisdiction whole for all such outlay and expense, provided that the Surety's obligation under this bond shall not exceed 125% of the penal sum of this bond. In the event that any actions or proceedings are initiated regarding this Bond, the parties agree that the venue thereof shall be Johnson County, State of Iowa. If legal action is required by the Jurisdiction to enforce the provisions of this Bond or to collect the monetary obligation incurring to the benefit of the Jurisdiction, the Contractor and the Surety agree, jointly, and severally, to pay the Jurisdiction all outlay and expense incurred therefor by the Jurisdiction. All rights, powers, and remedies of the Jurisdiction hereunder shall be cumulative and not alternative and shall be in addition to all rights, powers, and remedies given to the Jurisdiction, by law. The Jurisdiction may proceed against surety for any amount guaranteed hereunder whether action is brought against the Contractor or whether Contractor is joined in any such action(s) or not. NOW THEREFORE, the condition of this obligation is such that if said Principal shall faithfully perform all the promises of the Principal, as set forth and provided in the Contract and in this Bond, then this obligation shall be null and void, otherwise it shall remain in full force and effect. When a work, term, or phrase is used in this Bond, it shall be interpreted or construed first as defined in this Bond and the Contract; second, if not defined in the Bond or Contract, it shall be interpreted or construed as defined in applicable provisions of the Iowa Code; third, if not defined in the Iowa Code, it shall be interpreted or construed according to its generally accepted meaning in the construction industry; and fourth, if it has no generally accepted meaning in the construction industry, it shall be interpreted or construed according to its common or customary usage. Failure to specify or particularize shall not exclude terms or provisions not mentioned and shall not limit liability hereunder. The Contract is hereby made a part of this Bpgd. ?? r 1 West Riverbank Stabilization Project 0510 — Page 3 of 4 PRINCIPAL: Peterson Contractors, Inc.
