Project: Lagunitas Creek Floodplain Restoration for Coho Recovery (Phase II)

Description: This Project will implement water quality improvements identified in the San Francisco Regional Water Boards Sediment Maximum Daily Load (TMDL). This restoration includes the removal of hardscapes that currently restrict floodplain connection. Bridge bulkheads, retaining walls, and imported fill will be removed from the floodplain. Side channels and large woody structures will be built following the removal. This project will directly address these limiting factors by re-connecting floodplains, creating backwater alcoves and installing woody debris structures in Lagunitas Creek. The goal of this Project is to increase the abundance and function of winter rearing habitat for Central California Coast Coho Salmon.

Reference Number: 3600BQ1996013

Implemented By: Turtle Island Restoration Network dba Salmon Protection and Watershed Network

Objective: Specific objectives of this Project are to: 1. Increase the available floodplain habitat by 2 acres by removing 3,000 cubic yards of fill, concrete retaining walls and bulkheads from the channel to improve rearing habitat for juvenile salmonids and improve water quality. 2. Create 200 linear feet of off channel habitat that is connected to the main stem channel by grading, installing two (2) anchored large woody debris structures and five (5) unanchored living willow woody debris structures, and biotechnical features to provide velocity refuge and food resources. 3. Revegetate the 2-acre corridor with native riparian plant species following construction and removal of invasive vegetation.
