Green Company Conservation Design Forum 1997 Introduction The following is our wetlands delineation and habitat assessment for the proposed North Corridor - West Foster Road sanitary sewer line. The site is located north of Foster Avenue, approximately ½ mile west of North Dubuque Street, in Iowa City, Johnson County, Iowa (NWl/4, Sec. 4, T79N, R6W). As you are aware, wetlands in Iowa are regulated under Section 404 of the Clean Water Act, as administered by the US Army Corps of Engineers (COE). Several factors are considered in determining the existence of wetlands, including the presence ofhydrophytic vegetation (met when greater than 50% of the dominant vegetation is facultative, facultative wet, or obligate as stated in the "National List of Plant Species that Occur in Wetlands"), in association with hydric soils (as defined by the USDA Natural Resources Conservation Service), and evidence of wetland hydrology (standing water, saturated soils, water lines, and other indicators). In general, these three criteria must all be present in order to warrant wetland designation in accordance with the 1987 COE "Wetlands Delineation Manual." Based upon our site visit, we believe that part of the land within the proposed sewer line fight-of- way qualifies as regulatory wetland habitat. The COE is the ultimate judge and will make the final decision as to whether a given area is or is not regulatory wetland. Wetland Evaluation Procedure Preliminary Data and Synthesis Several documents were referenced prior to conducting the field work. These include the USGS Topographic Map of the region, the Johnson County Soil Survey, and aerial photographs of the project site depicting the location of the proposed sewer line. These were reviewed to assess the general character of the site, and to determine the presence of any potential wetland habitat on the property. As is apparent from the topographic map, the proposed right-of-way runs through a large ravine system north of Foster Road. A stream flows north to south through the base of the ravine, and is spring-fed via groundwater discharge and surface flow from the adjacent hillsides. According to the soil survey, the soils are mapped as Fayette silt loam, 25 to 40 percent slopes (163G). Fayette series soils are classified as a typic hapludal~, and are well-drained soils commonly found on ridges and side slopes in upland habitats. According to the aerial photographs of the project site, most of the proposed right-of-way is located along the base of the northeast facing ravine slope. The total length of the fight-of-way is approximately 900 feet; the width of the right-of-way is 50 feet, and includes a temporary Page 1 North Corridor - West Foster Road Sanitary Sewer Howard R. Green Company Conservation Design Forum 1997 construction easement. On-Site Evaluation A visit to the site was conducted on June 3rd 1997 in order to determine the presence of any wetlands within the proposed right-of-way. Wetlands were recognized based upon the combined presence of hydrophytic vegetation, hydric soils, and wetland hydrology. Field observations confirmed the presence of regulatory wetland habitat associated with a stream that flows through the MacDonald property. In the northern 3/4 of the right-of-way, the wetland boundary extend from the base of the slopes across the ravine (averaging approximately 50 feet in width). At the southern end, however, the wetland boundary narrows to include only the meandering stream channel and side slopes (approximately 20 feet in width). The stream is channeled through a culvert under a driveway, then exits the property under Foster Road. The total size of the wetland within the project area is 0.7 acres. On the day of the site visit, it was observed that the stream had 12 inches of flowing water within its channel. In general, the entire wetland can be characterized as a wet meadow dominated by the following plants: Carex spp., Eleocharis erythropoda, Laportea canadensis, Myosotis scorpioides, Phalaris arundinacea, and Salix nigra. Other plants noted from this area on the day of the site visit are listed in the appendix. The average mean wetness facultative wetland, and reflects the wetland characteristics present. Evidence of hydric soils and wetland hydrology were recorded from the area as well (see COE field data forms). The plants noted from the adjacent upland woods on the day of the site visit are found in the appendix. The average mean wetness is facultative upland, and reflects the upland (i.e., non- wetland) character of these woods. Not included within this inventory are several ornamental trees located near Foster Road, including burning bush (Euonyrnus alatus), spruce (Picea), hemlock ( Tsuga), and arbor-vitae ( Thuja). Summary of Wetlands and Regulatory Status Development within regulatory wetlands is prohibited unless documentation is submitted that proves that no practicable alternative to wetland modification exists. The COE is responsible for making a determination as to whether any proposed wetland modification will be permitted. Wetland modification will be permitted only when the proposed direct environmental impacts can be sufficiently evaluated, minimized, and mitigated. According to the engineering designs, the amount of wetland to be impacted by the project is 0.3 acres. Although degraded in areas, this ravine and adjacent wooded slopes have retained much of Page 2 North Corridor - West Foster Road Sanitary Sewer Howard R. Green Company Conservation Design Forum 1997 their natural character and beauty. Few spots remain in Johnson County, let alone within the city limits of Iowa City, that have the native floristic quality of this unique area. It is our understanding 'that this project and its anticipated wetland impacts have already been permitted for as part of a larger wetland mitigation project. Off-site wetland mitigation, however, does nothing for the negative impact that will occur to this site. If the sewer line is to be buried through this area, we recommend that the City and regulatory agencies agree to ensuring that this area is restored to its present condition after the project is completed. Included with this report are the following: · The appendix, including the fioristic quality assessment information. · The exhibits, including a site illustration depicting the location of the wetland on the property, photographs taken during the site visit, and various maps that pertain to the study. · Copies of the completed CO£ field data forms. Sincerely, Kenneth Johnson CONSERVATION DESIGN FORUM, Inc. Page 3 North Corridor - West Foster Road Sanitary Sewer Howard R. Green Company Conservation Design Foram 1997 Appendix Floristic Quality Assessment The following is a summary of the data generated using Wilhelm and Masters's Floristic Quality Assessment in the Chicago Region and Application Computer Programs, 1996. Plant nomenclature follows Swink and Wilhelm's Plants of the Chicago Region, 1994. Each inventory is arranged alphabetically, with each species preceded by its database acronym and coefficient of conservatism (C = 0 to 10, weedy to conservative), and followed by its wetness coefficient (W = -5 to +5, wet to dry), corresponding National Wetland Indicator Status (OBL = obligate wetland species, FAC = facultative species, UPL = upland species), physiognomy (A = annual, B = biennial, P = perennial, H = herbaceous, W = woody), and common name. Adventive species have entered the region since settlement and, therefore, are not integral to any presettlement plant communities. The tables that precede each inventory are a summary of the assessment data. The table in the left- hand comer is an analysis of the quality of the site. It shows the total number of species present, the mean coefficient of conservatism (MEAN C), the floristic quality index (FQI), and the mean wetness (MEAN W) followed by the average National Wetland Indicator Status for the site. These values are calculated once for native species only, and a second time including adventive species (W/Adventives), where the C values' are defaulted to zero. The columns to the right of the floristic quality data summarize the physiognomy of the vegetation at the site. The mean C is the average coefficient of conservatism for the site. The FQI is derived by multiplying the mean C by the square root of the number of species present. In general, if the mean C is 3.5 or higher, or the FQI registers in the middle thirties or higher,.it is relatively certain that there is sufficient native character in the site to be important in terms of a regional natural area perspective.
