The Black Mountain Road – Purissima Road Evacuation Route Project in Los Altos Hills, California, provides an important route of egress route for a significant portion of the Western area of the Los Altos Hills Community in the event of a wildfire evacuation. To secure the integrity of this route, Los Altos Hills County Fire District and Santa Clara County FireSafe Council propose a roadside treatment of hazardous fuels.

The total treatment of the project is approximately 8.4 miles of treatment when accounting for both sides of the route.


Right of Entry Permit (ROE) due back date: March 11, 2024

Goals for this project:

The immediate goal of this project is to make the roadway a safer evacuation route in an emergency or wildfire. The broader goals are to enhance fire resiliency by reducing ladder fuels and invasive plant species, and to improve roadside hardening along evacuation routes, which are significant benefits to the community and make District residents safer. This project enhances regional efforts to improve Santa Clara County’s evacuation route and shaded fuel break system. It also provides opportunities to protect or manage watersheds from future wildfires. Additionally, by reducing competition for light and water in the understory plants, shrubs, and young trees, and by treating hazardous trees when feasible, this creates a healthier forest and woodland for the benefit of the environment.
