Northwood Lake Water Quality Improvement Project

City of New Hope

Project Number: NL-1

Project Status   |  Active

This project is nearly complete. The storm water tank was fully operational in June and irrigated adjacent ball fields this summer. The educational sign is being designed and will be installed soon. The 2nd rain garden was planted with the fescue grass in June.

  • The storm tank is complete and buried and all pretreatment structures were installed.
  • The overflow rain gardens are complete.
  • Grass and other vegetation was planted throughout the site.
  • The official park opening event was held Spring 2017.
  • Jordan Pond and the overflow structure to Basset Creek at Hwy. 169 is complete and established. Trees were planted to help screen neighboring properties.

Project Funding   |   Grant Funded

This project was partially grant funded through a Clean Water Partnership grant from the Minnesota Pollution Control Agency in the amount of $300,000 and a Clean Water Fund grant from the Minnesota Board of Water and Soil Resources in the amount of $400,000. The project was funded at an amount up to $752,000 by the BCWMC's ad valorem tax levy via Hennepin County over two years, 2016 and 2017, and the City of New Hope provided additional funds of $300,000 toward the project.

Project Description

The BCWMC, in cooperation with the City of New Hope, constructed this storm water improvement project that will treat storm water runoff from more than 110 acres of currently untreated urban land.

The project includes the installation of a variety of Best Management Practices (BMPs) at two different locations adjacent to the lake. These BMPs will maximize storm water treatment while minimizing the amount of land removed from useable park space. The project includes constructing at the east end of Northwood Lake an underground storm water re-use system including a chamber with a 160,000-gallon capacity . The reuse system will irrigate adjacent ball fields, and an overflow system will direct extra runoff to rain gardens. At the west end of the lake, a wet ponding basin will be constructed to treat storm water runoff from rear-yard areas and Jordan Avenue.

This project is estimated to remove 22 pounds of phosphorous per year from entering Northwood Lake and will reduce the amount of other pollutants carried to the lake in storm water runoff and snowmelt.
