DESCRIPTION
McSorley Creek Pocket Estuary is located at Saltwater State Park in Des Moines. McSorley Creek supports spawning coho and chum salmon and cutthroat trout. The pocket estuary and marine shoreline provides rearing habitat for Chinook salmon as well as documented spawning habitat for forage fish. The development of the park dates to 1926 with the dedication of the park with construction of the facilities, including a historic fire pit, by the Civilian Conservation Crews in the 1930's. More recent alterations include shoreline and streambank armoring to protect a shoreline trail, volleyball court, restroom and picnic facilities. The restoration project will improve the lower portion of stream, pocket estuary, and nearshore damaged by the fill and shoreline armoring.
The McSorley Creek Pocket Estuary Restoration Project is currently in design phase; draft design has been completed for restoration elements of the project. The project is located in Saltwater State Park, Des Moines, along the eastern shore of Puget Sound. The project will improve natural shoreline processes and habitat in the McSorley Creek estuary and shoreline areas through removal of armoring. The project will: remove the rip-rap and groin at McSorley Creekâs mouth and create a pocket estuary, which have been nearly eliminated from South Puget Sound, to make the creek more accessible for fish including juvenile Chinook salmon, as well as allow sediments to again flow naturally northwards along the shoreline; remove the bulkhead along the shoreline north of the creek to reconnect 1000 ft of feeder bluff with the nearshore and reestablish natural sediment transport processes and recreate habitat for forage fish such as sand lance and surf smelt; redesign recreational amenities in areas impacted by restoration; amenities will be rebuilt at a higher elevation to reduce the risk of flooding expected to occur more frequently with sea level rise. Final design will begin August 2016 and include design for recreational elements, additional studies and analyses, SEPA checklist, permit applications, public outreach, and all interim and final design drawings, specs, and construction cost estimates. Funding request is to complete design for this restoration project.
