areas both immediately north and south of I-694 became land-locked. Subsequent <br />activities and observations include the following: <br />o In 1970, MnDOT raised the level of Rice St. at the north end of West Vadnais <br />approximately 8 feet as part of a construction project extending from County <br />Road E south to the B.N. Railroad overpass. <br />^ In 1985, the City of Little Canada raised the elevation of Country Drive about <br />1 ft. to 888.5 and installed a culvert under Country Drive at 885.5, which is <br />higher .than the pipe elevation under old N. Owasso Blvd. (the historical flow <br />path before construction of I-694). <br />^ In 2002, the Ramsey-Washington Metro Watershed District constructed an <br />outlet from Black Tern Lake to the County Ditch 16 system. The control <br />elevation is 886.1. <br />^ The Grass Lake WMO Water Management Pian (Sept. 2001) provides the <br />following information. The normal water elevation of West Vadnais is 881.9. <br />In 1990 or 1991, MnDOT installed a vault under Rice St. at the request of <br />Grass Lake WMO to accommodate a gate valve to separate Grass Lake and <br />West Vadnais. The gate valve was not installed. Under high water conditions, <br />Grass Lake and West Vadnais elevations are expected to be similar. Under <br />extreme rainfall conditions, Grass Lake is expected to flow toward West <br />Vadnais. <br />^ High water levels have been measured in Grass Lake over the last two years, <br />with corresponding reports of high water in West Vadnais. During this time <br />the Rice St. centerline elevation at its lowest point was only about 0.5 ft. <br />above the West Vadnais elevation. St. Paul Region Water staff reported in <br />2002 that high water in West Vadnais was flooding the parking lot and pump <br />house area at the Vadnais Station. <br />I am hopeful that your organization will consider this request to be consistent with its <br />surface water management role. Please call me to discuss the matter more fully at (651) <br />482-5230. <br />Sincerel <br />f~ <br />Terr/ry Ndonan <br />Project Manager -Water Resources <br />
