SUBJECT- Heights T: 1 leighis STAN R1:polt'1' !Tanning F, Zoning Commission 'July 11, 1974 F-7409. Referral by City Council to rezone a tract of land located immediately east of the southerly extension of from an R3 Zone to an R3A ZoneOlive Court in University. STAFF ANALYSIS: The above described 13,400 square foot tract owned by Ms. Vivian M. Smith, was zoned R3A in 1962, as part of the enhensive City Zoning Ordinance, in accordance withtmenthetComprehensive Plan developed by Ilarland Bartholomew and Associates to zone the arca for multifamily use. The City had, in 1962, developed two multifamily zones --the R3A and R313 Zones. Since both zones permit a considerable high density of development, the City subsequently instituted an R3 Zone with a much more restrictive density. In 1972, the City adopted an ordinance to rezone an area including the subject tract from an R3A Zone to an R3 Zone but not before the owner of said tract had secured a building permit and pro- ceeded to construct a 10 -unit multifamily building on the subject tract. As a result of the ordinance adopted, the use of the pro- perty because "nonconforming" because of a higher density than the R3 Zone would allow. On March 29, 1974, said owner filed a writ with the District Court for the right to use the property in a manner as provided by an R3A Zone. As a result of the case, the Court declared the ordinance "invalid with respect to plaintiff's property ... but only in respect to plaintiff's property" and "the aforesaid ordinance having thus been declared invalid as to plaintiff's property, the zoning there- of remains R3A...". STAFF RECOMMENDATION: be taken to fulfill any obligation by tract from an R3 Zone to an R3A Zone. While it appears the Court has already declared the subject tract zoned R3A, it is the staff's recommenda- tion that appropriate steps the City to rezone the subject r ' +•ij , Js'k � r t 1 � 1' w 1 h 111 "%1. i�ttJ � i' , � 1 ,}'a•+ , I � '�..

Ordinance to amend the Zoning Code establishing accessory use and parking requirements for the CB and CBS Zones. Council referral. STAFF Attached hereto is a proposed COMMENT: ordinance establishing parking requirements for the CB Zone. Sec are fic included as an addendum to the Parkingland SidelYardnordinance recently adopted. Public and commercial parking facilities are "permitted" uses allowed in the CB and CBS Zones and private Parking facilities are considered as "accessory" uses in said Zones. All parking facilities in the CB and CBS Zones, with the exception of parking spaces for a hotel or motel, are per- mitted only upon the approval of the City Council. STAFF REPORT Planning & Zoning Commission June 13, 1974 SUBJECT: S-7408. Final Plat of Court Hill -Scott Boulevard Addition, Part 3, located north of Court Hill -Scott Boulevard, Part 2, and south of Lemme School; submitted by Plum Grove Acres Inc.; date filed: 6/4/74; 45 -day limitation: 7/19/74. STAFF The subject 12.14 acre tract ANALYSIS: is zoned R1B and consists of 35 lots for an average density of 2.88 lots per acre or an average lot size of approximately 11,300 square feet per lot excluding street area. The plat conforms with the approved preliminary plat and with the requirements of the Subdivision Ordinance with the exception of the following minor discrepancies: 1. The boundary of the tract should be tied to "some corner of the congressional division of which Iowa City, or the addition thereto is a part". 2. All utility easements should be indicated on the plat including: a. A five foot utility easement along the east lot line of Lot 48, and b. Ten foot utility easements along the south lot lines of Lots 58 and 70, since half of the required 10 foot easement had not been provided along said lot lines common to lots in Court Hill -Scott Boulevard, Part 2. For clarity, the following minor notations should he included on the plat: 3. The words "FINAL PLAT", 4. The boundary line of Lemme School where it intersects the boundary line of the subject tract, and 5. The words "LEMME SCHOOL" to indicate the location of the School with respect to the boundary of the plat. STAFF RECOMMENDATION: It is the staff's recommen- dation that the subject plat be approved if the above items 1 through 5 are added to the plat. -2 - STAFF The Subdivision Ordinance COMMENT: requires that "accurate dimensions for any property to be dedicated or reserved for public, semi-public or community use" be illustrated on the final plat. Utility easements are easements granted to utility companies including the Iowa -Illinois Gas and Electric Company, a semi-public company, for their use. Subdividers have indicated that the Gas and Electric Company is not in a position at the time a final plat is filed to inform the subdivider of where utility easements should be located. Consequently, many unnecessary easements are provided within a subdivision or certain necessary easements are excluded. It would be highly desirable if the utility companies would determine in advance of the filing of a final plat where utility easements should be located so that every lot owner or builder would have knowledge of where easements are located by reference to the final plat. +ARE M 1 Mal i '�1!I Jw(1 I RIX REQUEST AREA -oL- .3 T � Yom. �_ 1_�L� �_ � 1.. _ • �� it 4lI Tl 690 -1 N RR H GRAPHIC SCS.,._ - - - 1 J R341C 2 RRA FILE NUMBER: s-8 City of Iowa City MEMORANDUM DATE: May 20, 1974 TO: City Council FROM: City Manager RE: Ralston Creek Study Purpose The occurrence of heavy spring rains, requests for building activity near the flood plain, and the annual review of the Capital Improvements Plan and Budget have all contributed to a revived citi- zen interest in Ralston Creek. Subsequently the City Council has requested that this brief status report be filed with the Council in order to clarify any misunderstanding relative to the progress which has been made on the Ralston Creek flooding problem. Flood Plain Ordinance The City Council presently has tabled a Flood Plain Ordinance for Ralston Creek which was recommended to the Council by the Plann- ing and Zoning Commission in March of 1972. The deferment, by tabl- ing, came after a public hearing in April of 1972 and a second read- ing of the ordinance in May of 1972. The City Manager had recommended the deferral of the passage of the ordinance in order to be assured that the eventual resolution of the flooding problem would be compati- ble with the control function of an adopted flood plain ordinance. Activities The following report is an excerpt from a Department of Communi- ty Development progress report: "In April, 1974, the City contracted for aerial photography so that the flood plain maps could be redrawn. The original mapping was based on December, 1964 aerial photography with some update. The maps that were used for the 1972 ordinance are somewhat obsolete in various places considering that there have been bridge replace- ments and other changes in the Creek cross section. Currently, the Soil Conservation Service is in the initial stages of a study to suggest alternative solutions to the flooding by proposing impoundment structures as well as other types of facili- ties that could possibly reduce the flood plain of Ralston Creek to its present stream bed. It is anticipated that they would be able to come to the City with preliminary alternatives by early fall of 1974. A meeting was held on Wednesday, Mav 8, to have all parties Memo to: City Council -2- May 20, 1974 (Soil Conservation Service, City, Department of. Natural Resources, and the United States Geological Survey) concerned touch base with respect to their individual activities. The following represents an indicnLion of the status of those various activities: The Surface Water Division of the U. S. Geological Survey will be preparing flood hazard maps for the Federal Insurance Administration as part of the Type 15 Rate Making Studies for the HUD Flood Insurance Program. They will define a hundred and five -hundred year flood and the floodway. They will also be presenting information on the ten-year flood. They are coordinating all of their activities with the Iowa Natural Resources Council in that the Resources Council is the state agency responsible for this action. They will be delineating the flood hazard areas within the City limits for the Iowa River, Ralston Creek, Rapid Creek, Clear Creek, and, if we can provide the mapping, for the unnamed creek currently flowing through Willow Creek Park. (As an aside, it has been determined that that creek can be named by sending in a suggested name for the creek to a central agency which delineates geographical names. We will be pursuing this in the very near future.) The Soil Conservation Service the ground control for the mapping area. They will then upon receipt continue their study of alternative from Des Moines will be providing for the Ralston Creek Flood Plain of flood plain maps from Iowa City structure locations. The City of Iowa City will be providing 100', 2' contour, for the flood hazard areas what we currently call Willow Creek flowing We will also be providing ground control in be provided by the SCS. This ground control hired consultant. flood plain maps at 1" = for Ralston Creek and for through Willow Creek Park. those areas that will not will probably be by a The City will also be hiring a consultant in the next several months to look at a broader water resources management study for Ral- ston Creek (and it is hoped also that the study will have applicability to Willow Creek, Rapid Creek, and Clear Creek flood plains). This study will look at other alternatives for long range solutions to flooding as alternatives to the dams and diversion tunnel as well as looking at any other types of treatments that would be useful in the Ralston Creek Watershed in conjunction with the SCS structures. The Iowa Natural Resources Council will be involved in that they are already working directly with the SCS and the Surface Water Division of the U. S. Geological Survey with respect to flood plain delineations on Ralston Creek. Jim Cooper of the Iowa Natural Resources Council and S. W. Wiitala of the Geological Survey both have agreed that it would be a valuable activity to map the flood plain for Willow Creek. The Geo- logical Survey would provide us with the delineation of the flood plain for Willow Creek. They would provide field surveys of the cross sections of the Creek and we as a City would provide the contour mapping. It is anticipated that the remapping of Ralston Creek will be accom- plished in the next two months in that aerial photography was taken on April 25, 1974. Memo to: City Council -3- May 20, 1974 In that we do not have the detailed work program yet from the Soil Conservation Service, we cannot totally prepare, as of this date, a study design for the Ralston Creek Flood Plain Management Study to be accomplished by a consultant. It would be anticipated khat this study design would be available by the end of June and that hiring for a consultant could proceed very shortly thereafter." Summary It would appear that the reasons for recommending deferral of the adoption of a flood plain ordinance in 1972 are still valid and operative in the spring of 1974. A flood plain ordinance should be regarded as one part of a comprehensive program to resolve the problems associated with the annual flooding of Ralston Creek. Such an ordinance should not only serve as a regulating device but it should also be an integral part of a comprehensive policy for community action. It must be based on the best information obtainable and employ the latest tech- nology which is currently being developed by the multi -agency research and planning effort. Therefore, it is recommended that the City Council should continue to support the research and planning efforts and defer consideration of the passage of a flood plain ordinance until the latter part of 1974.
