The Marin RCD coordinates several green projects annually via the Conserving Our Watersheds (COW) Program to promote and support the advancement of water quality improvements within the district’s watershed boundaries including Tomales Bay, Lagunitas, Stemple, and Walker Creek Watersheds.
The West Marin agricultural community has actively implemented projects with the Marin RCD since the 1960s. Successful partnerships have formed between local, state and federal funders, and agricultural producers who have found commonality in restoration goals. Years of practical experience and trust have led to comprehensive watershed enhancement projects. Some outcomes of completed projects include increases in bird populations and increases in the presence of anadromous fish at restored sites. In recent years, the Marin RCD culminated this effort into one program entitled the Conserving Our Watersheds (COW) Program.
The goal of the COW program is to support agriculture and the environment by implementing successful voluntary environmental improvements on agricultural lands in West Marin’s watersheds. The objective is to reduce fine sediment delivery by 75-95% for repairs to headcuts, gullies and streambanks; and to reduce fine sediment delivery by 50-75% for riparian fencing and revegetation projects. Another important goal is to continue to build excellent stewardship practices into the everyday work of ranching and farming in west Marin County. This is accomplished by providing private landowners and agricultural producers with 1) project planning and permitting assistance, 2) technical/engineering expertise, 3) construction contractors, and 4) maintenance and monitoring assistance.
The COW program utilizes the Marin Coastal Watersheds Permit Coordination Program (PCP), which provides coordinated regulatory review for implementation. Seventeen (17) types of conservation and restoration practices are intended for grazing lands to reduce erosion, enhance aquatic and terrestrial habitat and assist ranchers with sound stewardship in the Marin County coastal watersheds.
Projects are selected through a process that has proven highly successful for other recent Marin RCD grant programs: First, landowners and local groups submit candidate projects through an open proposal process. Second, a Technical Advisory Committee visits, reviews and ranks the projects, and then make recommendations to the Marin RCD Board for approval.
The implementation of management practices are designed to have a significant beneficial effect on the environment and ecological processes within the watershed.
1) Reduce erosion and sedimentation to improve important spawning areas & reduce sedimentation of estuarine habitats.
2) Reducing the amount of pathogens entering the watershed by fencing out stream corridors thereby improving waters for recreational uses.
3) Planting along streams to cool stream temperatures for wildlife habitat & provide improved habitats for threatened & endangered species.
4) Reduce runoff pollution by fencing out riparian areas, installing biotechnical streambank repairs, planting stream corridors & repairing gully erosion.
5) Improve upstream grazing lands to indirectly improve water quality at nearby beaches, estuaries & coastal waters by reducing pathogens, E. coli, sediments and nutrients.
