SALT RIVER ECOSYSTEM RESTORATION PROJECT LOWER AND MIDDLE PHASE 2 A
The Salt River Ecosystem Restoration Project (SRERP) was a multifaceted restoration project designed to restore ecological, geomorphic, and hydrologic function within the Salt River watershed. The Salt River watershed is an approximately 47-square mile watershed located within lower reaches of the Eel River basin.
CHANNEL Restored: 1 mile
Cubic Yards Moved: 140,0000
Contract amount: $4.8m
YEAR COMpleted: 2015
LAND TYPE: Coastal Riparian
This restoration project was comprised of two phases. Phase 1: Restore tidal marsh within the Riverside Ranch.
Phase 2: Restore channel from Riverside Ranch to Perry Slough.
The purpose of the project was two-fold; to enhance habitat along the channel riparian corridor, and to alleviate flooding pressure to adjacent agricultural lands.
Both phases of work included clearing and grubbing vegetation for grading activities, sediment hauling with specialized equipment, water main replacement, installation of large wood habitat structures, and installed of native seed mixed with mulch. The project also called for sediment revetments and site maintenance.
The restoration activities within the Riverside Ranch and Salt River Channel required significant grading activities. Hanford excavated 80,000 (Phase 1) and 60,000 (Phase 2) cubic yards of soil. The soil was placed as berms within the project area or were thinly spread on neighboring agricultural land.
Hanford installed a variety of relevant BMPs to protect the surrounding habitats from project activities, and to meet the SWPPP requirements. The second phase of work was constructed with an accelerated schedule in order to complete work before the predicted El Nino winter season.
