PURPOSE/ACTION REQUESTED
Authorize the execution of a joint powers agreement (JPA) with the Vermillion River Watershed Joint Powers Organization (VRWJPO) and the City of Lakeville for the Lake Marion Phosphorus Treatment Project.

The Jaguar Pond did not function as designed due to continuous groundwater seepage, and base flow conditions resulted in capacity reduction and ultimate failure of the stormwater basin. The City of Lakeville, in partnership with VRWJPO and Dakota County, took the lead in designing and constructing improvements to the pond.

A JPA was drafted to allow all three agencies to jointly cooperate in completing the Jaguar Pond improvements for the Lake Marion Phosphorus Treatment Project. Under the terms of the JPA, Dakota County, VRWJPO, and the City share equally in the design costs of the pond of $5,800 for each agency.
