Document Description
The proposed project will restore tidal marsh habitat, improve flood storage on lower Pinole Creek, and provide recreational opportunities along the Bay Trail. The tidal marsh restoration would be accomplished in phases through the excavation of approximately 40,000 cy of fill previously deposited on the site, installation of an improved box culvert and bridge structure, and removal of the existing 36" wide outflow flap gate culvert. The project will also temporarily install sheet piling along the northern portion of Pinole Creek to isolate tidal waters from project work and the eventual removal of the sheet piling to allow tidal connection from Pinole Creek. An 18" drain culvert will also be abandoned in place with a concrete plug end as necessary. A 2 acre marsh upland transitional area owned by the Chelsea-by-the-Bay HOA will be incorporated.
