Jaycee Park Raingarden

Overview

The City is partnering with the Dakota County Soil & Water Conservation District (SWCD) to install a 600 square foot raingarden in the Jaycee Park parking lot. The raingarden will capture runoff from the parking lot and nearby ball field. Stormwater modeling predicts the raingarden with reduced sediment and phosphorus water pollution by 0.22 tons (or about 440 pounds) per year and 1.43 pounds per year respectively. The project is funded through City of Rosemount Stormwater Utility Fees and the Clean Water Land and Legacy Amendment (Watershed Based Implementation Funds). The SWCD is managing grant funding, design, and construction oversight.

The garden will be planted with shrubs native to the state of Minnesota.
