Compost Cost-Share Program for Farmers & Ranchers

SB 1383 is California’s climate law designed to cut methane emissions by keeping organic materials—like food scraps and yard clippings—out of landfills. To meet this goal, every city and county in California must purchase and distribute compost, mulch, or renewable natural gas in amounts tied to their population size.

This Placer RCD pilot program helps the City of San Mateo meet these procurement targets while making compost more accessible and affordable for local farmers and ranchers. This project is a partnership between the City of San Mateo and Placer RCD.

Funding for this Program has been fully allocated!

This program provides an opportunity for Placer County Farmers and Ranchers to access compost to help with nutrient cycling, boost biology, build soil structure, and improve infiltration and water holding capacity. Compost can be used on:

Rangeland (for restoration or degraded soil)
Cropland
Orchards
Vineyards
Pastures

Successful applicants will receive up to $67 per ton in cost-share assistance—covering most, if not all, of the compost and delivery costs directly to your farm or ranch. (Note: cost for spreading is not covered under this program). The Placer RCD must source compost from approved compost facilities that are certified by the state of California.
