MEMORANDUM TO: Mayor Fahey & Members of the City Council FROM: Greg Schroeder, Public Works Director DATE: January 16, 2002 RE: Black Tern Pond Outlet Black Tern Pond is located just south of Country Drive and west of Spruce Street. This pond does not have an outlet. The water level in this pond rises to a point where it will eventually flow across the St. Paul Regional Water Services land to our storm water system on Spruce Street. Last year the water level stayed up very high and resulted in flooding of Country Drive. In addition, the high water level backs up into our catch basins on Country Drive to within an inch of the road surface. Last winter the Country Drive storm sewer catch basins froze solid, thus, blocking any melted snow from existing the road surface and creating a safety problem. These concerns were raised with the Ramsey - Washington Metro Watershed District and they agreed to install an outlet in Black Tern Pond at no cost to the City of Little Canada provided we maintain it. As shown on the attached sketch, the outlet it will drain Black Tern Pond via a 12" pipe across the St. Paul Regional Water Services property to our existing storm sewer system on Spruce Street. In order for the City of Little Canada to maintain this outlet we need permission from the St. Paul Regional Water Services to enter upon portions of their land. Based on the above Council action is needed on the following staff recommended items: 1) Agree with the Ramsey - Washington Metro District that the city of Little Canada will maintain the Black Tern Pond outlet as part of our storm sewer system. 2) Execute the Twenty Third Rider to our agreement with the St. Paul Regional Water Services, which provides for the construction and maintenance of this outlet on their land.
