WHEREAS, the Vadnais Lake Area Water Management Organization at the request of the County, convened a series of meetings of potential project partners beginning in April 2003 to evaluate the need and impact of restoring the historic West Vadnais Lake outlet flow path to Lake Gervais; and WHEREAS, the project partners determined that a new West Vadnais Lake outlet is needed to provide a stable, low flow outlet for water derived from GLWMO and the Vadnais Lake Area Water Management Organization and flowing into the District, and to protect the interests of the County and Board with regard to high water levels on West Vadnais Lake; and WHEREAS, the District has determined that water flow from the new West Vadnais Lake outlet pipe will not increase 100-year return frequency high water elevations for Lake Gervais or other water bodies downstream of West Vadnais Lake; and WHEREAS, the District desires control of the West Vadnais Lake outlet pipe to regulate the seasonal period of water flow directed to Lake Gervais; and WHEREAS, the Minnesota Department of Transportation (MnDOT) plans to reconstruct I-694 east of Rice St, beginning in 2005, which provides a unique opportunity for construction of a new outlet for West Vadnais Lake under I-694; and WHEREAS, MnDOT has developed construction plans for the I-694 project which incorporate construction plans for an outlet from West Vadnais Lake at an elevation of 881.9 (1988 datum); and WHEREAS, the estimated 95% construction cost for the West Vadnais outlet is $99,666; and WHEREAS, the County and Board receive the primary benefit of the proposed West Vadnais Lake outlet, with lesser, but significant, benefit to GLWMO and the Vadnais Lake Area Water Management Organization; and WHEREAS, the MnDOT Road Turn Back Program has agreed to pay 50% of the total construction cost of the proposed West Vadnais Lake outlet on the basis of alleviating Rice Street flooding potential, and to account for MnDOT funding participation in the West Vadnais Lake outlet project in determining eligible costs to the County in the future State/ County turn back agreement for Rice Street; and WHEREAS, the Vadnais Lake Area Water Management Organization is not willing to contribute to the West Vadnais Lake outlet project if the County meets its project cost share obligation solely through the application of MnDOT Road Turn Back Program funds for Rice Street, as proposed, and is therefore not included as a project partner; and WHEREAS, future land use or environmental changes may significantly impact the intended function of the proposed West Vadnais Lake outlet pipe; and WHEREAS, the County will be party with MnDOT to the I-694 reconstruction project agreement for that portion of the project dealing with the West Vadnais Lake outlet; and PW2004- ~(n 2 of 7
