Purgatory Creek Streambank Restoration
The proposed project is to alleviate streambank erosion along approximately 300 linear feet of Purgatory Creek within Purgatory Park in the City of Minnetonka and the Riley-Purgatory-Bluff Creek Watershed District. The work will involve realigning the stream to the north and installing instream structures such as toe-wood structures to protect the outer banks and highly used city trail. Cross vanes and augmented riffles will be installed for channel stability and fish habitat. A high visibility wet meadow plant community restoration will further stabilize the project reach.
This Purgatory Creek stabilization project aligns with the Riley-Purgatory-Bluff Creek Watershed District Watershed Management Plan. The effort is supported in Chapter 9.0 Implementation: The Next 10 Years of the watershed management plan, section 9.1.2 Creek Management and section 9.13 Opportunity Projects. The project is closely aligned with the district's goals and strategies and represents an opportunity for partnership with the City of Minnetonka for a high visibility restoration effort with significant interpretive education for the public.

(a) $39,500,000 the first year and $39,500,000 the second year are for grants to implement state-approved watershed-based plans. The grants may be used to implement projects or programs that protect, enhance, and restore surface PreviouswaterNext quality in lakes, rivers, and streams; protect groundwater from degradation; and protect drinking PreviouswaterNext sources. Projects must be identified in a comprehensive watershed plan developed under the One Watershed, One Plan program and seven-county metropolitan groundwater or surface PreviouswaterNext management frameworks as provided for in Minnesota Statutes, chapters 103B, 103C, 103D, and 114D. Grant recipients must identify a nonstate match and may use other legacy funds to supplement projects funded under this paragraph. This appropriation may be used for: (1) implementing state-approved plans, including within the following watershed planning areas (see Chapter 40 Article 2 Section 6(a) (2) for the list of watershed planning areas: seven-county metropolitan groundwater or surface PreviouswaterNext management frameworks; and(3) other comprehensive watershed management plan planning areas that have a board-approved and local-government-adopted plan as authorized in Minnesota Statutes, section 103B.801. The board must establish eligibility criteria and determine whether a planning area is ready to proceed and has the nonstate match committed.
Stabilizing the 300' of streambank, creating remeanders, and reconnecting the floodplain, the project will reduce streambank erosion and sedimentation while increasing riparian habitat. Est. removals include 1.16 Ton/yr TSS and 0.43 lbs/yr of P.
