The 400 Project

The Medicine Lake Excess Nutrient Total Maximum Daily Load study indicates a volume reduction of 10% will reduce phosphorus loading to Medicine Lake by over 300 pounds. The 400 Project is a grant program supporting projects to reduce existing impervious surface and increase infiltration through the implementation and use of porous pavement(s) and/or reinforced turf technology. While new construction has more opportunity to include water quality improvements, The 400 Project is unique in that can assist with redevelopment projects where space is limited.
The 400 Project is a priority for the City of Plymouth because there is opportunity to address water quality impairments, excess water volume, protect recently constructed improvements, and to provide best management practices in areas of the City where those practices are few and the contribution to water quality impairments is high. The 400 Project will eliminate 400 acres of existing impervious surface in Plymouth over the next 15 years. Additionally, porous pavement(s) and reinforced turf technology have both aesthetic and functional advantages over traditional conservation practices. Eligible participants in this program include commercial, industrial, institutional, public, or residential properties as well as public improvement projects.
