Altamont Evacuation Route Project

Project Updates

The 2026 maintenance treatment was completed on June 12, 2026.

Project Description

The Altamont evacuation route in Los Altos Hills, California provides a significant route of egress/ingress for the northern portion of the Los Altos Hills community in the event of a fire. To secure the integrity of this egress/ingress route, Los Altos Hills County Fire District and Santa Clara County FireSafe Council propose a roadside treatment of hazardous fuels.

You may read more about Altamont project goals on the Santa Clara County FireSafe Council website.

Read the media release.
