Green Lake and Nest Lake are economically important recreation areas near the City of Spicer. The expansion of State Highway 23 to a four-lane facility will go through the city of Spicer and the environmentally sensitive Green Lake/Nest Lake recreational area. Due to economic importance, the highway’s proximity to the lakes, the abundance of wetlands in the area, and limited space for stormwater treatment in the highway right-of-way, stormwater management and water quality issues were controversial.

## Future actions

Post construction monitoring will be conducted in one location within the city of Spicer by Mn/DOT and in two other locations within the city of Spicer by a private consultant through October 2006. These locations were monitored for one year before the project commenced and during project construction.

A minimum of yearly inspections to all components of the stormwater management system will be conducted. Grit chambers will be cleaned out as necessary but at a minimum of twice yearly. Periodic maintenance will be performed on the settling basins and ponding areas to ensure continued proper functioning.
