The proposed project will restore a 4,240-foot long reach of Lakeville Creek that flows through Sonoma Land Trust’s 1,142-acre Sears Point Ranch Preserve and the adjacent Sonoma Raceway property in summer/fall 2023.
The project reach is deeply incised, resulting in reduced connectivity with its floodplain for the majority of the channel length. The channel and overall site conditions make the area suitable for restoration of a multi-threaded channel with extensive floodplain inundation. The design will bring the current channel back to its original grade and provide the contours for natural establishment of an anastomosing network of channels. A complex mosaic of channels, wetlands and uplands is expected to provide more diverse plant and wildlife habitat, allow for greater infiltration and storage of water, and result in a greater likelihood of sustaining wetlands into the future. The process will reconnect the channel to the surrounding floodplain and increase the duration of the seasonal water table in the adjacent floodplains and seasonal wet meadows.
The proposed project will restore the habitat located at Lakeville Creek by:
1. Grading throughout the project reach to replace the incised channel with a broad “Stage Zero” wetland complex with no defined channel; grading will consist primarily of excavation in the upper project reach and fill in the lower reach.
2. Revegetating with native perennial seed and plugs throughout the restored “Stage Zero” valley wetland complex, willow cuttings in clusters along the reach, and limited upland woody plantings.
3. Adding fencing to exclude livestock while vegetation is establishing and to facilitate limited grazing access after establishment.
