ARP - Agriculture Residential Planned, APZ - Agriculture Production Zone
The Marin County Department of Public Works is proposing to conduct maintenance activities to rehabilitate existing road pass-through culverts and repair eroded roadside embankments (slip-outs). The proposed project would address culvert deficiencies using a variety of maintenance treatment types specific for each location. Culvert maintenance treatment types may include: extending culvert outfall pipes to avoid flanking or undermining; grouting or lining culvert interiors; paving culvert inverts; replacing damaged sections or failed pipes in-kind; installing larger diameter pipes where culverts are undersized; repairing existing inlet drop structures placing rock riprap at culvert inlets and/or outlets; constructing concrete headwalls; and improving fish passage.
Point Reyes-Petaluma Rd, Highway 1, Platform Bridge Rd, Lucas Valley Rd, Nicasio Valley Rd, Sir
Lagunitas Creek, Nicasio Creek, San Geronimo Creek
The Project area encompasses approximately 14 miles of roadway in West Marin County.
