Consultation has concluded.

The Lynmar Basin is a low-lying, open space that currently briefly detains stormwater before it makes its way to Lake Edina and eventually Nine Mile Creek through storm sewer pipes. The location was identified as an opportunity to better manage stormwater as part of a larger effort to improve downstream water resources.

The retrofit project will better utilize the space to capture and clean more stormwater than it already does today. The existing dry pond area will be expanded and deepened to promote stormwater infiltration. The infiltration basin will be planted with native trees, shrubs, and forbs.

The project benefits include;

  • Less polluted water entering Lake Edina and downstream water resources
  • Reduced flooding in the South Cornelia neighborhood
  • Enhanced natural resources, including improving pollinator habitat
  • A portion of the space kept open for passive recreation, and a new walking path

This project is done in partnership with the Nine Mile Creek Watershed District.
