----- ----------- shore of the lake. This pond has a surface area of 0.95 acres and permanent pool storage volume of 3.5 acre-feet. No additional ponding facilities are anticipated for this drainage area. The eastern drainage area includes runoff from approximately 58 acres of project area located between Fairview Avenue and Lincoln Drive and between County Road C and Terrace Drive. Runoff from the eastern drainage area currently flows to a wetland (DNR #206W) located in Oasis Park west of Lincoln Drive. Runoff is collected by existing street storm sewer and a public ditch which outlets into a treatment basin located directly south of the wetland. Future ponding needs in this area will be designed to meet all NURP standards, and will be reviewed prior to any proposed redevelopment. XXI. Sanitary Sewers Sewage waste produced by Twin Lakes redevelopment will be discharged into the Roseville sanitary sewer collection system. The redevelopment area includes an extensive sanitary sewer network with trunk mains along Cleveland Avenue, County Road C and Fairview Avenue and several shorter lateral sewers throughout the interior and perimeter of the site. All of the sanitary sewer facilities flow into an existing Metropolitan Council Environmental Services (MCES) interceptor sewer, which bisects the project area from west to east along the Iona Lane right-of-way and dedicated easements. The interceptor sewer ultimately discharges at the Metro Sewage Treatment Plant in St. Paul. The interceptor sewer increases in size from 36 inches in diameter near Cleveland Avenue to 42 inches in diameter near Fairview Avenue. The proposed improvements include the extension of an 8-inch diameter sanitary sewer along the proposed Mount Ridge Road from Iona Lane north to County Road C-2, No capacity improvements will be required at the Metro Plant or with interceptor sewer facilities as a result of the proposed project. Proposed uses in Twin Lakes include office, office-laboratory, office-showroom-warehousing, biotechnical, biomedical, and hi-tech software and hardware production uses with support services such as limited retail, health, fitness, lodging and multifamily housing. Generally these types of uses do not produce, handle or dispose of significant amounts of hazardous materials. It is possible that some occupants may use or handle hazardous materials as a part of their business. Any occupant who utilizes hazardous materials would be required to confonn to all existing environmental laws and regulations in place at the time of development. XXII. Wildlife Habitat and Threatened or Endangered Species The diversity and population of wildlife species in an area is directly related to the type and quality of habitat that exists in that area. The study area is in a part of Roseville that has been fully developed for 30 years, A large percentage of the study area is comprised of buildings, parking areas, and other impervious surfaces and provides little or no wildlife habitat opportunity, The only areas of wildlife habitat found in the Twin Lakes area are classified as either urban/suburban; lawn/landscaped areas or disturbed open space, A small amount of woodlot is found as fringe to the 20
