Stabilization and Restoration of the Highland Ravine
The Highland Ravine is a large bluff area in central St. Paul that has become highly eroded due to hydrologic changes associated with urban development. During rain and snow melt events, water and sediment moves down slope onto private residential properties causing significant flooding and sedimentation. In addition, sediment-laden water from the gullies goes into the St. Paul storm sewer system which discharges, untreated, directly to the Mississippi River.
This project will include gully stabilization, woodland restoration, and upland project construction to increase infiltration and storage. Stabilizing and restoring Highland Ravine will prevent future flooding, erosion, and sedimentation to local properties and improve the
The 20-member BWSR board consists of representatives of local and state government agencies and citizens. Members are appointed by the governor of the state of Minnesota consistent with Minnesota Statutes 103B.101.

(a) $13,750,000 the first year and $13,750,000 the second year are for pollution reduction and restoration grants to local government units and joint powers organizations of local government units to protect 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 (SSTS) projects and stream bank, stream channel, and shoreline restoration projects. The projects must be of long-lasting public benefit, include a match, and be consistent with TMDL implementation plans or local water management plans.
Gully Stabilization - Mississippi River Proposed Reductions: 91 Phosphorus lbs/year and 11.5 Sediment tons/year
CRWD stabilized the north and south ravine areas of Highland Ravine. Rock grade control structures and toe protection measures were installed to stabilize the ravine channels. A stormwater pond was installed at the downstream end of the north ravine for flood control. The site was planted with native seed mix. Restoration of the ravine woodland side slopes did not extend as far up the slope as originally intended at the time of the grant application, which reduced annual total phosphorus load reductions. The completed project is estimated to reduce sediment loads by 28 tons per year and phosphorus loads by 11 pounds per year.
The source of additional funds varies from project to project, but generally consists of federal, local and non-public sources.
