New Hope 45th Avenue Pond Improvements Project
This project will consist of retrofitting a dry storm water basin, constructing a new pre-treatment cell, creating new wetland, and reconfiguring the existing inlets and the outlet for better water quality treatment. This project is specifically identified in the Twin-Ryan Lakes TMDL.

(b) $2,800,000 the first year and $3,124,000 the second year are for grants to watershed districts and watershed management organizations for: (i) structural or vegetative management practices that reduce storm water runoff from developed or disturbed lands to reduce the movement of sediment, nutrients, and pollutants or to leverage federal funds for restoration, protection, or enhancement of water quality in lakes, rivers, and streams and to protect groundwater and drinking water; and (ii) the installation of proven and effective water retention practices including, but not limited to, rain gardens and other vegetated infiltration basins and sediment control basins in order to keep water on the land. The projects must be of long-lasting public benefit, include a local match, and be consistent with TMDL implementation plans or local water management plans. Watershed district and watershed management organization staff and administration may be used for local match. Priority may be given to school projects that can be used to demonstrate water retention practices. Up to five percent may be used for administering the grants (2010 - Runoff Reduction)
The project's pond reconstruction was completed in Summer 2011. The final design included relocating the storm sewer outfall to the pond to increase residence time and maximize the amount of treatment. The project is expected to remove about 37 pounds of total phosphorus and 10 tons of total suspended sediment per year.
