I I I I I I I I I I I I I I 2.0 3.0 "Helium Street Extension-C.O.R. Project No. 02-20" in a separate feasibility report. A small, portion of this. project area immediately north of Pondvale Estates will benefit from the storm drainage and detention pond being provided in this project. Therefore, a proportional percentage of the cost of the storm drainage system including right-of-way will be added in to the Project No: 02-20. The other project is the residential subdivision northeast of this subdivision referred to as "151St Ave./Fluorine St.-152® Ave.- C.O.R. Project No. 02-21" in its separate feasibility report. PROJECT NEED The project as proposed serves these needs: · Provides connection to the City's water system as v~ell as completing the looping of the 12" trunk water main stubbed to both sides of the subdivision. This will also provide fire protection for the subdivision. · Provides the access to the interconnection of the proposed water improvements in the two 'companion projects discussed in Section 1.0. · Provides connection to the City's sanitary sewer system. · After installation of the underground utilities, replaces the existing paved street havin9 bituminous curb with a permanent urban paved street with concrete curb and gutters and improved storm drainage. This complies with the policy of requiring concrete C & G in all subdivisions in the urban area that have water and sewer. · Provides a positive ovedlow to the wetlands for the subdivision and for a portion of the Helium St. Extension project located directly north of the subdivision. EXISTING CONDITIONS The proposed project area consists of approximately 10 acres of land that is developed as single family residential lots. The lots are owned in eight groups of two or three each. Sale of the unused portions of the lots may occur in the future. The land within the subdivision is gently sloped with elevations ranging from 895 to 875. A. Streets and Storm Drainaqe The existing streets in the subdivision are paved bituminous with bituminous curbs, 31 feet width to back of curbs. The pavement is approximately 17 years old and is in fair condition. An overlay would be required within two years. There is not an underground storm drainage system to collect the storm water. Currently, a portion of the area in the subdivision drains to a small detention basin, which does not have an outlet. This basin currently is located in the middle Page 2 G:\MunicipaI~ARAMSEY\632\RA632FSRI .doc -239-
