DESCRIPTION
Complete final design, permits, and construction specifications for the South Prairie Creek Floodplain Restoration Project between river mile 4.0 and 4.6. Project actions for implementation include: 1. Placement of mid- channel wood structures along a 0.6 mile reach of South Prairie Creek to reverse channel incision and promote of spawning sized sediments 2. Construction of an inset floodplain along the right bank to create a system of perennial side channels through introduction of base flows from South Prairie Creek and interception of groundwater 3. Aggressive planting of floodplain riparian communities 4. Demolition of bridge crossing on the main channel of South Prairie Creek and installation of bridge crossing over Silver Springs 5. Design and installation of interpretive materials for public access and education regarding the cultural and natural resources present on the property
The South Puget Sound Salmon Enhancement Group completed pre-final design plans and construction specifications for the South Prairie Creek Floodplain Restoration Project between river mile 4.0 and 4.6. Project actions for implementation include: 1. Placement of mid- channel wood structures along a 0.6 mile reach of South Prairie Creek to reverse channel incision and promote of spawning sized sediments; 2. Construction of an inset floodplain along the right bank to reconnect an exisiting side channels through introduction of base flows from South Prairie Creek and interception of groundwater; 3. Aggressive planting of floodplain riparian communities totaling 63 acres??; 4. Demolition of bridge crossing on the main channel of South Prairie Creek and installation of bridge crossing over Silver Springs; ?5. Demolition of 7 former dairy structures and out buidlings on the left bank riparian buffer; 6. Design and installation of interpretive materials for public access and education regarding the cultural and natural resources present on the property.
The end goal of this project is to improve instream habitat, off-channel habitat, riparian function, and floodplain connectivity to increase the overall capacity of this stream reach to support juvenile rearing, adult spawning, and egg incubation for pacific salmon, specifically Puget Sound Chinook, steelhead, coho, chum, pinks, and coastal cutthroat. This phase 0 project would developed final plansand construction specifications for implementation of a project serving these stated goals. Project proponents are building a funding porfolio and targeting a 2017-2018 consruction season.
