Page 3 <br />station currently has a capacity of approximately 200 to 230 gallons per <br />minute. From there the lift station flows by a six inch force main <br />easterly approximately 900 feet and discharges into a 12 inch gravity <br />sanitary sewer which then flows into a 27 inch trunk sewer. The <br />southern portion of the site is served by 36 inch Metropolitan Waste <br />Control Commission interceptor running through the Minnesota Department <br />of Transportation pond and then easterly. The project upon final <br />completion when added to the off -site flows would produce a total flow <br />which is greater then the existing city facilities. Conceptual plans <br />have been prepared to modify the city's facilities to adequately meet <br />the needs of the entire area. Either this alternative or other feasible <br />alternatives are available to mitigate and control the situation. These <br />expenses are primarily to fall to the project. <br />The project site at present drains to two primary receiving faoilities <br />to handle surface water run-off. The first is a pair of parallel storm <br />sewer pipes that are 24 and 36 inches in diameter which runs diagonally <br />across the parcel along what was identified as County Ditch 110. 5 in the <br />northern third of the site. This system presently receives the bulk of <br />the run-off of the site as well as carrying drainage from Cleveland <br />Avenue, Wilson Pond, Langdon Lake, and other areas to the east Cleveland <br />Avenue. The southern portion of the site where the Garret Trucking firm <br />currently exists sheet drains into the Minnesota Department of <br />Transportation pond. From there it exits northerly along I-35W via a 24 <br />inch storm pipe. The proposed project would incorporate a series of <br />ponding areas located within the development. The northern ponds would <br />discharge into the County Ditch 5 pipes, the central portion across <br />Cleveland Avenue to an existing storm pond identified as Wilson Pond <br />near County Road C-2 and the southern portion into the MnDOT area after <br />proceeding through wa1<r quality treatment facilities. In particular, a <br />separate pond is proposed to be provided on the southern portion of the <br />project site to filter the stows water prior to its discharge into the <br />MnDOT pond area. The amount of hard surface area will increase as was <br />previously stated in this document. The total volume of storage <br />available within the storm sewer systems would increase slightly. <br />Development of the storm sewer systems will require permits from the <br />Rico Creek Watershed District and the City of Roseville. In addition, <br />work in and : and the MOOT Fond may require a permit from the <br />Minnesota Department of Transportation and/or the Minnesota Department <br />of Natural Resources, depending on the final location and elevation of <br />the work. <br />The project proposer as part of the plan has formulated an erosion and <br />sediment control segment. The following measures hcvo been identified <br />for use throughout the duration of and where applicable upon completion <br />of the construction project: (a) Contractor shall place straw and hay <br />bales, snow fence or equivalent siltation fences at key locations on the <br />plans, and they shall be maintained until completion of the grading, <br />paving and landscaping work. (b) All disturbed areas not hard surfaced <br />shall receive mulch within 15 days of finished grading operations. <br />(e) Part of the paving, on -site catch basins shall be protected by hay <br />or straw bales. (d) By completion of the project, ground cover will be <br />maintained. <br />
