This past winter, Lake Minnewashta experienced significant ice heaving, due to changing temperatures over recent months.
When there are rapid temperature fluctuations, like we experienced this winter, ice sheets expand and push against the shoreline, creating ice “heaves” or “ridges”. These heaves can greatly alter and affect the lake’s shoreline, often requiring homeowners to consider implementing or enhancing shoreline stabilization methods.
If you are considering shoreline stabilization work this year — including installation or repair of riprap, native shoreline plantings, sand blankets, retaining walls, etc. — reach out to the Minnehaha Creek Watershed District’s (MCWD) Permitting Staff for technical assistance or to apply for a Shoreline Stabilization Permit. MCWD’s Permitting Staff can guide you through the permitting process, answer any permitting questions you have, and provide technical guidance as you consider which stabilization options work best for you.
MCWD Permitting Staff can be contacted at permitting@minnehahacreek.org or (952) 641-4532.
The City of Chanhassen may also have permit requirements to ensure the work is completed safely and meets rules outlined in City Code. Please review regulations before starting work and reach out to the City’s Engineering Department atengdept@chanhassenmn.gov or (952) 227 –1160 if you have questions.
Additional Resources for Residents
Residents can apply for the City of Chanhassen’s Low Impact Development (LID) Landscape Grant, to install landscape features that manage and treat stormwater runoff. Eligible homeowners, businesses, and community groups can apply for up to $1,000, which would be equally matched by the project owner.
Residents who are interested in native planting for their shoreline can explore Carver County’s shoreline habitat program, which helps homeowners install native habitat shoreline buffers. Residents can also apply for Blue Thumb’s Lawns to Legumes grant program, to receive support for native planting projects.
For technical assistance, homeowners can also reach out to Metro Blooms, which provides consultations and design guidance for sustainable landscapes.
