The Mariposa County Public Works Department is comprised of nine divisions:

Roadside Vegetation Control
Backpack Application
The County of Mariposa, Public Works Department, maintains approximately 600 miles of public roads and Zone of Benefit Roads, including actively managing vegetation control utilizing chemical means.

On occasion, requests are received from local property owners to establish a "no-spray" zone on road frontage bordering their property. Property owners interested in filing an opt-out/no spray agreement must complete and submit a Roadside Vegetation Control Agreement to the Public Works Department in order to be considered for the opt-out option.

The Roadside Vegetation Control Agreement and Information Sheet are located HERE. The documents are also available at the Public Works office.

Tree Mortality Mitigation

Over the next several months, Mariposa County Public Works Department will be mitigating tree mortality hazards along County maintained roadways and properties. Working with the assistance of Cal Fire Madera-Mariposa-Merced Unit, the activity of falling trees and the associated cleanup may cause traffic delays and short term road closures, or may require the closure of parks and other properties. Thank you in advance for your patience, and for being alert to the work zones to ensure you and the workers remain safe.  If you have any questions please feel free to contact Russ Marks at (209) 966-5356.
