To: Plan Reviewers From: Karen Chandler, on Behalf of Grass Lake WMO Board Subject:. Grass Lake WMO Board Responses to Comments on Draft Watershed Management Plan Dater. December 26, 2000 c: Grass Lake WMO Board and Staff Page: 11 Met Council Items circled "l 0" The Met Council believes the GLWMO plan has the opportunity and responsibility to address the need to retrofit and re-design the stormwater systems in the fully developed areas and identify areas where retrofitting can occur. GLWMO Response to Comments: For existing stormwater discharge points (outfalls), the GLWMO plan encourages the cities to provide pretreatment of stormwater prior to its discharge to wetlands and other water resources (Section 5.3, C. Stormwater System Design Requirement Policies -Water Quality, policy 2). In Section 5.10, Evaluation and Accountability, policy 4(b), one of the performance standards notes that "pretreatment at existing discharge points can be accomplished as part of road reconstruction and other projects, through addition of detention ponds, grit chambers, diversion to existing ponds, etc." Roseville and Shoreview continue to look for these opportunities and report them to the GLWMO Board. The cooperation between the two member cities, their willingness to work together, and their understanding of the GLWMO goals has resulted in successfitl ret~'ofitting projects. For example, as part of the cooperative West Owasso Boulevard project, the two cities are using the project as a means to improve/increase stormwater treatment in already developed areas. In this case, Roseville and Shoreview are looking into land purchase to achieve this goal. The GLWMO will consider adding a "removal of direct discharges "goal to Section 5.2 or 5.3 of the GLWMO plan. The GLWMO agrees that it is a good idea to identify stormwater retrofit locations. A policy will be added to Section 5.3 and a task will be added to Table 6-I of the GLWMO plan calling far the GLWMO to identify retrofit locations along the larger/trunk stormwater systems. Obvious Local/smaller opportunities or techniques for smaller systems may also be identified. The member cities would then incorporate this information into their local plans a11d build upon it. The GLWMO and the member cities intend to seek grants and other funding opportunities to offset implementation costs. The policies in Section 5.11 will be revised to reflect this intention. The GLWMO Board will look uito outside funding sources once projects are closer to implementation, since funding opportunities could change by that time.
