Project Number: 2015CR
The BCWMC approved the project's 90% design plans at its June 2015 monthly meeting. The restoration project is being constructed in two phases, each under separate contract. Phase One includes stream bank shaping, placement of field stone rock and 12-inch bio logs, and repair of storm sewer outlets. Phase Two includes the establishment of native vegetation along the stream. Phase Two will commence immediately following the completion of Phase One and will continue over two additional growing seasons to ensure proper vegetation establishment. Phase One started in November 2015 and is anticipated to end in June 2016.
The initial shaping and stabilization work in Areas A, B, C1, C2, C3, and E is complete. The contractor, Rachel Contracting, will return in spring 2016 for final detail and grading work including relocating portions of the trail away from the stream in Area E. Clearing for creek corridor access is complete in Areas D1 and D2, and stabilization work is underway.
The bid package for Phase Two of the project, the native vegetation establishment, will go out in late winter 2016. It is anticipated that the total contract amount for Phase One and Phase Two work will be within the BCWMC's overall project budget.
The estimated cost of this project is $1,503,000 of which up to $503,000 will be funded by the BCWMC's Capital Improvement Program Closed Project Fund and $1,000,000 will be funded by the BCWMC's 2014 ad valorem tax levy to be collected via Hennepin County in 2015.be
The BCWMC, in cooperation with the City of Golden Valley, is restoring sites along the 9,500-foot reach of Bassett Creek from the intersection of 10th Avenue North and Rhode Island Avenue North to Duluth Street.
The project's feasibility report identified up to 29 sites where bank erosion, bank failure, and infrastructure repairs are needed. Restoration techniques will include bioengineering methods, which primarily uses vegetation materials, and structural methods, which use rock and other non-vegetative materials. The bioengineering and structural methods for this project both incorporate the use of stone toe armoring and installing a section of fieldstone boulder wall. The restoration techniques will be determined site by site and will incorporate the techniques that will be most successful for that site.
The completed project will reduce the total phosphorous load entering the creek by an estimated 60-100 pounds per year and will reduce the total suspended sediment load by an estimated 140,000-200,000 pounds per year.
