The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-SON-33545-R3, pursuant to Section 1602 of the Fish and Game Code to Sonoma Land Trust.
The project is limited to restoration of Lakeville Creek along an approximate 4,240 feet reach. Restoration will include grading of the incised channel, revegetation with native wet meadow species and bands of willow (Salix sp.), and protection of the site from grazing impacts with wildlife friendly fencing. Restoration will also include the
removal of an existing culvert crossing of Lakeville Creek and replacement with a stabilized rock ford crossing of the same size, approximately 40 square feet. Restoration will follow the “Stage Zero” methodology, which involves restoring the channel bottom to its historic geomorphic grade through a combination of excavation of anthropogenic fill in the upper project reach to create a wider inset valley floor and filling the incised channel sections in the middle and lower reaches to the existing alluvial fan elevations. The goal is to raise the water table and create the distributary channel network and wet meadow ecosystem that was present before incision of the channel. Excess sediment from the upper reaches and fill for the lower reaches will be balanced to avoid the need for material off haul or soil import. The project area will encompass approximately 9.2 acres with grading activities limited to approximately 5.4 acres. After completion of the grading, erosion control and revegetation will be implemented. Revegetation will consist of seeding with native wetland species mix, wet meadow plug plantings, riparian plug and shrub plantings, bands of willow pole plantings, and native upland grass seed mix based on slopes and desired habitat types post-grading
