Ramsey, MN 55303 RE: 153rd Ay. N.W. between Variolite St. N.W. and C.R. 83 Environmental Assessment WorKsheet Metropolitan Council District 9 Dear Mr. Schroder: Council staff has conducted a review of this environmental assessment wor~heet (EAW) to determine its adequacy and accuracy in addressing regional concerns. The staff review has found a number of problems in the EAW regarding its completeness and accuracy with respect to regional concerns and issues of consistency with Council policies. These concerns are summarized below. The Council's concerns focus on three issues--wetland impacts, sUrface water runoff, and the Council's Interim Nonpoint Source Pollution Strategy. The proposed project would result in the loss of 1.31 acres of type IV protected wetland (DNR # 111P). The proposer plans on creating 2.62 acres of wetland to mitigate the wetland impacts. Any alteration of protected waters must have a permit issued by the Minnesota Department of Natural Resources. Under policies 3-4 and 3-5 of the Council's Water Resources Develol~rnent Guide/Policy ?lan, roadways should be routed to avoid damage to water and wetlands; ff impacts cannot be avoided compensating mitigation should be provided. The EAW includes two alternate alignments for the roadway which would minimize wetland impacts. One of these alternate alignments should be chosen for the road. According to the EAW, the proposed reconstruction will result in 3.7 additional acres of impervious surface, which will increase runoff volume and peak runoff rate. Drainage from the road will flow through ditches to the wetland, which has no natural outlet. The Council strongly recommends pre-settlemenl of runoff prior to discharge to surface waters. While site constraints due to the wetlands make pretreatment of stormwater.difficult, some form of treatment prior to discharge to wetlands is highly desirable. The city of Ramsey has not adopted the Council's Interim Strategy to Reduce Non. point Source Pollution To all Metro]golitan Water i~odies. The Interim Strategy requires local governments to adopt as part of their comprehensive plans and official controls, the EPA's National Urban Runoff Program (NURP) design standards for new stormwater ponds, and MPCA's urban best management standards (or their equivalent) for new development or redevelopment, by January 1, Recycled Paper q/
