Mr. Steve Ach July 18, 1997 Page Two The development proposes two outlets, one to Evans Street and a second one to 193rd Avenue further to the east. In meetings with the Developer, he has suggested posting the Evans Street exit as no right turn in an effort to encourage outbound traffic to use the 193rd Avenue exit. We support this suggestion; however, it is worth noting that it will be virtually impossible to enforce. B. STORM DRAINAGE There is an existing trunk storm sewer line which crosses 193rd Avenue from the large retention pond on the north side and traverses approximately the location of the proposed access, through the parking lot area, and outlets into the existing wetland south of this proposed development. The Site Plan shows two proposed retention ponds on either side of the proposed 193rd Avenue outlet. Storm drainage calculations will be needed at some point in the future to ensure that storm sewer facilities are adequate sized and that Best Management Practices are met relative to quality control prior to discharging into the wetland to the south. Them currently is a minor storm drainage problem on 193rd Avenue in that the catch basins at the Iow point just north of this proposed development cannot accept the volume of water in large rainfall events. This causes overtopping of the mad and some erosion in this ama. This problem will likely be solved by this development in that the water can now find its way down the proposed access to 193rd Avenue. The Developer is aware of this and has indicated that he will provide catch basins along this access road to pick up any additional water generated from 193rd in large rainfall events. C. UTILITIES There is an existing trunk sanitary sewer line which runs north and south along Evans Street on the west side of this development; therefore, adequate sanitary sewer facilities exist to serve this development. There is also a watermain in Evans Street which has a stub toward this development. Watermain along 193rd Avenue is also stubbed out. It will be relatively easy to loop this watermain through the development to strategically placed hydrants where the Fire Chief determines for fire protection. Each building should have a sanitary sewer and water service. If any portions of the building are to be sold at a later date to individual owners, each segment to be individually owned would need a separate service. D. GRADING No Grading Plan was submitted with the Site Plan. At some point in the future, a Grading Plan will need to be submitted, reviewed, and approved. The elevation of the two buildings adjacent to the large wetland to the south will need to be carefully reviewed. The current
