Cherokee Heights Stormwater Management and Ravine Stabilization Project
The Cherokee Heights Ravine receives untreated stormwater runoff from a 70-acre residential area. The ravine is at the upstream end of Lilydale Regional Park. High flow rates and velocities of untreated stormwater through the Cherokee Heights Ravine has caused severe erosion contributing to the instability of the adjacent banks and resulting in sediment and phosphorus loading to downstream Pickerel Lake. The project will reduce pollutant loading by treating stormwater and stabilizing the approximately 300 foot long Upper Cherokee Heights Ravine. The project will be conducted in partnership with St. Paul, Mendota Heights, and West St. Paul and is estimated to reduce annual sediment and phosphorus loading by 17 to 41 tons and 17 to 41 pounds respectively. This represents about 37%-89% of the needed load reduction for Pickerel Lake.
$6,882,000 the first year and $12,618,000 the second year are for grants to protect and restore surface water and drinking water; to keep water on the land; to protect, enhance, and restore water quality in lakes, rivers, and streams; and to protect groundwater and drinking water, including feedlot water quality and subsurface sewage treatment system projects and stream bank, stream channel, shoreline restoration, and ravine stabilization projects. The projects must use practices demonstrated to be effective, be of long-lasting public benefit, include a match, and be consistent with total maximum daily load (TMDL) implementation plans, watershed restoration and protection strategies (WRAPS), or local water management plans or their equivalents. A portion of these funds may be used to seek administrative efficiencies through shared resources by multiple local governmental units.
This project is estimated to reduce sediment loading by 17 to 41 tons/year and TP loading by 17-41 lbs/year. This represents about 37%-89% of the 46 lbs/year TP load reduction from watershed sources recommended in preliminary drafts of the Pickerel Lake TMDL.
