Bristol & Mavelle Park/Lynmar Basin Stormwater Project
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.

Planning for an in-person meeting
Share on Facebook Share on Twitter Share on Linkedin Email this linkWith the loosening of restrictions and new guidance from the CDC, we think we can safely meet in-person outdoors. We're planning to share a couple concept designs at an outdoor meeting in the park in the first part of July. We'll also provide an online opportunity to review and provide feedback.

Thanks for connecting with us!
Share on Facebook Share on Twitter Share on Linkedin Email this linkPeople seemed eager to see what a project here might look like. We have some general ideas and now that we've had a chance to hear from you, we're ready to start drawing up a conceptual plan. Then we'll share a draft with you and seek your feedback.
We heard that this space is used for unstructured open play like golfing, football, whiffle ball, and sledding, as well as for passive recreation like walking, dog walking, viewing open green space, and occasional picnicking.
We heard;
- Keep it green
- Keep it open
- Enhance stormwater management
- Enhance the natural resources
- Protect high value trees and plant additional trees where you can
- Protect people from flooding
- Enhance the nature aesthetic

Flood Risk Map

You'll also be able to see the storm sewer network to get a feel for the infrastructure buried underground that moves surface water from this neighborhood to Lake Edina, and eventually to Nine Mile Creek.
Visit www.EdinaMN.gov/flooding for resources including actions you can take to reduce your exposure and vulnerability to flooding.

Share your thoughts - online, in person, or both!
Share on Facebook Share on Twitter Share on Linkedin Email this linkWe'll be in the park tomorrow, April 20th from 4-5:30pm to learn more from you about current uses, desires for the future, and concerns about a potential project.
Can't make it? You can participate online by completing the survey, asking a question, dropping a pin on the map, submitting an idea, or giving us a call.
We'll provide a summary of what we heard later this week.
