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.

    At its March 16th meeting, the NMCWD Board of Managers adopted a resolution ordering the project to proceed to a detailed design phase.

    The next step is for City and Nine Mile Creek Watershed District to enter into a cooperative agreement describing how we intend to work together through design, construction, and beyond.

    At their September 21st meeting, City Council approved the concept plan.

    Staff will move into the next phase which is a feasibility study.

    This closes the public input portion of the project design.

    We've considered your feedback and developed a refined concept design. You can download a copy of the Concept Plan Summary Report in the Documents section.

    Staff will present the report to City Council at their September 21st meeting and recommend approval of the concept plan. If approved, the next step is to ask the Nine Mile Creek Watershed District to authorize staff to do a feasibility study which moves the project from the big picture/conceptual idea phase into the detailed engineering and landscape design phase.

    You can watch the meeting live or catch a recording later.

    Staff will present the refined concept to the City Council at their September 21st meeting. Staff will make a recommendation and City Council will make a decision.

    We'll share the refined concept with you on this webpage about a week before the September 21st meeting.

    Thank you for your input. We're using what we heard to refine the concept design. We plan to share a refined concept design with you in September on this project webpage.

    Thanks for your input on the initial concepts.

    This is what we heard:

    • General support for the primary benefits - stormwater runoff collection and flood risk reduction.
    • General support for the secondary benefits – habitat enhancements, park improvements, and educational opportunities.
    • Preference for the concept that shows the path following the treeline along Lynmar Lane on the east edge of the park.
    • Support for the path alignment in concept #2 because it preserved valued open play space.
    • A 5-foot wide trail is preferred over an 8-foot wide trail.
    • No support for a retaining wall.
    • Desire for the planted area to look deliberate, with a recommendation to give the natural planting area a visual edge, perhaps with a mowed border.
    • Desire for tall trees and flowering trees, shrubs, and plants.
    • Desire to save trees along the edges and plant new trees as much as possible.
    • Most, but not all, supported removing trees and shrubs in the low portions of the park to accommodate a lowered, planted area.


    Your input on the initial concepts is welcome through August 6th. We'll use the input to refine the concept design.
