Low cost environmental services and cooperation behveen units of Iocal government to implement important monitoring efforts that support stormwater infiltration goals. 3. If approved, this partnership between the City, MDH, Ramsey County-Environmental Services, and Ramsey Conservation District will lead to a low cost program to protect public drinking water supplies in. the Grass Lake WMO. 4. This type of project combines the issues of surface water, stormwater infiltration, and groundwater quality and will provide measureable results to document use of a new stormwater infiltration technology. In summary, RCD has contributed $1,650 of in-kind services toward the success of this project. RCD asks that the Grass Lake Watershed Management Organization's Board of Commissioners consider funding the remainder ($1,425) of this monitoring effort to assure that inf Itrated stomnvater is not impacting groundwater supplies used for drinking water in the Grass Lake WMO. We are confident that this proposal is the lowest cost option for completing these tasks. Please call me at (651) 2.66-7273 with any questions. Sincerely, Geoffrey Nash, P.G.
