<br />waters. Drainage from the project area is divided into three separate drainage basins, the <br />western, central, and eastern as described below. <br /> <br />The western drainage area includes approximately 50 acres located between Prior A venue and <br />Cleveland A venue and between County Road C and County Road C-2 in the project area. <br />Runoff from approximately 18 acres of the Centre Pointe development and an existing 6 acre <br />parcel east of Cleveland Avenue will also be treated in the western pond. The western drainage <br />area pond is situated directly north of and outlets to a wetland (DNR #62-50) located between <br />Cleveland Avenue and I-35W. The western pond, which is under construction and is expected <br />to be completed in June 1997, will meet all National Urban Runoff Program (NURP) standards. <br />This pond has a surface area 2.1 acres and permanent pool storage volume of 12.5 acre-feet. <br />No additional ponding facilities are anticipated for this drainage area. <br /> <br />The central drainage area includes approximately 18 acres from parcels 14 through 19 and 50 <br />acres of existing redeveloped parcels located between Prior Avenue and Fairview A venue and <br />between County Road C and Terrace Drive. Runoff from approximately 20 acres of land <br />located south of County Road C is also directed to the central drainage area through existing <br />storm sewer. The central drainage area pond outlets to Langton Lake (DNR #49W)and is <br />located along the southeast shore of the lake. This pond has a surface area of 0.95 acres and <br />permanent pool storage volume 00.5 acre-feet. No additional ponding facilities are anticipated <br />for this drainage area. <br /> <br />The eastern drainage area includes runoff from approximately 58 acres of project area located <br />between Fairview Avenue and Lincoln Drive and between County Road C and Terrace Drive. <br />Runoff from the eastern drainage area currently flows to a wetland (DNR #206W) located in <br />Oasis park west of Lincoln Drive. Runoff is collected by existing street storm sewer and a <br />public ditch which outlets into a treatment basin located directly south of the wetland. Future <br />ponding needs in this area should be designed to meet all NURP standards, and will be reviewed <br />prior to any proposed redevelopment. <br /> <br />19. Water Quality - Wastewaters <br /> <br />a. Describe sources, quantities, and composition (except for normal domestic sewage) of all <br />sanitary and industrial wastewaters produced or treated at the site. <br /> <br />Response: Proposed uses are office/showroom and office/manufacturing. These uses produce <br />normal domestic sewage. <br /> <br />b. Describe any waste treatment methods to be used and give estimates of composition after <br />treatment, or if the project involves on-site sewage systems, discuss the suitability of the site <br />conditions for such systems. Identify receiving waters (including groundwater) and estimate <br />the impact of the discharge on the quality of the receiving waters. (If the discharge may affect <br />a lake, consult EA W Guidelines about whether a nutrient budget analysis is needed.) <br /> <br />Response: None. <br /> <br />c. <br /> <br />Ifwastes will be discharged into a sewer system or pretreatment system, identify the system and <br />discuss the ability of the system to accept the volume and composition ofthe wastes. Identify <br />any improvements which will be necessary. <br /> <br />#24397 <br /> <br />14 <br />
