The San Rafael Rock Quarry has proudly served the Marin County community and the State of California for more than 100 years. Throughout its history, the Quarry has been a vital resource for our local community. In 1986, Bill Dutra purchased the Quarry, and the Dutra family has owned and operated this facility ever since.
We take great pride in our deep and longstanding working relationship with the State of California, and more importantly Marin County. We have strong ties with all cities in Marin County as evidenced by our disaster prevention and emergency relief work.
