Cold Spring Southwest Stormwater Infiltration Project
The purpose of this project is to retrofit 24 acres of existing development within a 138 acre subcatchment to improve the water quality of Cold Spring Creek which is a designated trout stream. This project is a the first phase of a multiphase approach to provide stormwater treatment in the 138 acre subcatchment area.
LOCAL LEVERAGED FUNDS
The City of Cold Spring is looking to retrofit 24 acres of existing development within a 138 acre subcatchment of the City to improve the water quality of Cold Spring Creek, a designated trout stream. The large amounts of hard surfaces within the subcatchment area do not allow for rainfall or snow melt to soak into the ground. The stormwater carries with it sediment, bacteria, automotive fluids, and other pollutants. Cold Spring staff has frequently witnessed sediment plumes, the color of chocolate milk, at the storm sewer outfalls. The goal is to reduce the pollutant load (chocolate milk colored discharge) currently entering the Creek from this area by capturing and treating the first one-quarter inch of rainfall coming from the impervious surfaces. Water quality Best Management Practices will include bioretention basins and/or infiltration trenches.
