Our division, Roads, holds primary responsibility for maintaining most of the roads in the unincorporated areas of our county. The exceptions are state roads, city streets, and non-county maintained roads. To enable us to handle problems more efficiently, we've divided Marin County into two areas: West Marin and Urban Eastern Marin.

We work to serve the county's residents and visitors with the least inconvenience as possible. To that end, we often do our work during the late night/early morning hours so as to cause as little impedance to traffic flow as possible. Come rain or shine, our staff are out on the County roadways to ensure the right-of-ways remain open and safe for travel.
