Sound Salmon Solutions completed Cherry Creek Phase 1 at the confluence with the Snoqualmie River just north of Duvall, improving riparian habitat in an agricultural zone, and increasing in-stream edge habitat surface area and complexity. This project treated 1,000 lin. feet of Cherry Creek (360 ft. island perimeter + 325 ft. Cherry Cr w/ new channel left bank around island + 315 Cherry Cr w/ right bank channel around island = 1000 ft. = 0.19 mi) and included: • Widening the mouth of Cherry Creek. • Constructing a low broad island (8,238 sq. ft.) at the mouth of Cherry Creek that added 360 ft. of edge habitat in the widened mouth. The recontoured bank has 36 pinned logs with rootwads facing out (filled with riprap and spoils) and bioengineered terraces constructed with soil filled coir wattles. The entire island was capped with excavated topsoil, covered with erosion control fabric and seeded with erosion control grasses. • Constructing the island created a 185 ft. secondary channel off the left bank. • Removing Himalayan blackberry (Rubus armeniacus) and a small patch of invasive knotweed (Polygonum sp.) from 0.7 acres along both sides of Cherry Creek (640 linear ft.) by brush cutting, scraping, and then burying the remaining biomass on site, in an excavated pit under 9 ft. of fill. • Removing exposed and buried riprap along a total of 630 ft. (0.12 miles) of stream banks from the mouth of the original channel on both banks up stream and used as ballast for pinned LWD in construction of the island. • Regrading the creek banks to a minimum of a 2:1 slope with 10' planting benches on both banks creating 7,030 sq ft of floodplain area. • Installing 13 LWD clusters, 6 on the left bank and 4 on the right and 3 "super clusters" at the broad points of the island. • Planting 60 native trees and 275 native shrubs along 640 ft. of stream bank to a 35' wide buffer as well as on the island for a total of 0.7 acres. (Several hundred more plants including willow and dogwood stakes will be installed in 2020 as part of two King County grants - Cooperative Watershed Management and One Million Trees.) There were significant cost increases over the course of the project due to spoils disposal expenses; a total of $293,679 in additional funding was requested and approved by Snohomish Watershed Lead Entity and RCO/SRFB to afford excavation in the floodplain. The project addresses the need for Chinook spawning and rearing habitat in Cherry Creek, as expressed in the Snohomish Basin Salmon Conservation Plan, which lists Cherry Creek as a primary rural restoration stream and this section of the Snoqualmie as a primary mainstem restoration area. The project also benefits other salmonids which use Cherry Creek, including Steelhead, Coho, Chum, and Pink.
