Document Description
The Harney Road Bridge (Marian Rose White Bridge), located within the Sonoma Development Center in Sonoma County, is a two-lane reinforced concrete bridge that crosses Sonoma Creek. Overland drainage has resulted in erosion in the vicinity of the bridge sidewalk foundation and eastern abutment. The Project will repair the erosion damage, recontour upland areas to direct overland flow away from the abutment into an existing outfall, and apply a patch to the bridge sidewalk in the vicinity of the eastern abutment. No activities will take place below ordinary high
water of Sonoma Creek, and thus no in-water work will occur. Concrete pouring would occur in the dry season between June 15 and October 15. The Project will install Controlled Low-Strength Material (CLSM) in the void area beneath the bridge caused by the erosion. Best management practices (BMPs) will be installed to prevent erosion and to prevent any concrete from reaching Sonoma Creek. BMPs include erosion and sediment control consistent with California Stormwater Quality Association (CASQA) Construction Best Management Practices Handbook
including straw wattles, silt fencing and hydroseeding with native grass seed.
