I - <br /> .._.. . - PROJECT ERPERIENCE <br /> • <br /> SEH has provided water resource ce management to communities and ' <br /> counties both in the metropolitan area. and outstate. During <br /> I <br /> community development, storm water management and detention basin <br /> design were practiced, at SEH long before they became standard <br /> design procedure. SEH engineers have prepared comprehensive <br /> I - <br /> storm water management plans, detailed storm drainage studies and <br /> j complete plans and specifications,,. for .construction. . SEH also <br /> provides resident inspection during construction. ' SEH has worked <br /> in conjunction with the various approving agencies . such as <br /> 1 Mn/DOT, Ramsey and Hennepin County, the Department of Natural <br /> Resources,- the Corps of Engineers, U.S. Fish & Wildlife Service, <br /> Minnesota PCA, and numerous watershed districts and watershed <br /> organizations. <br /> f <br /> The following is a partial list of . surface water management <br /> projects. • <br /> Roseville, Minnesota <br /> i <br /> SEH is currently updating Roseville' s Surface Water Management <br /> Plan. Working with the Grass Lake W.M.O. , the Rice Creek <br /> Watershed District, and the Central Ramsey W.M.O. , we will be <br /> providing the City with a "user' s manual" for surface water <br /> management, outlining specific practices to be used for ditches, <br /> ponds, wetlands and lakes. Each water body will be classified <br /> based on use and function to manage the entire city system. The <br /> 1 study will also include water quality and sediment__and-erosion --- -- <br /> control analysis. <br /> Our study includes the use of the SCS TR-20 program to model . <br /> existing conditions and calibrating the model based on available <br /> historical data. Future land use is then input so that potential <br /> problem areas can be identified. The program will establish the <br /> 100 year critical water surface elevations, the 100 year peak • <br /> discharge rates and analyze the necessary storage requirement to <br />
