Elena-Fremont Evacuation Route Project

Project Description

Elena-Fremont evacuation routes in Los Altos Hills, California provide a significant route of egress/ingress for the northern portion of the Los Altos Hills community in the event of a wildfire. To secure the integrity of these egress/ingress routes, Los Altos Hills County Fire District and Santa Clara County FireSafe Council propose a roadside treatment of hazardous fuels.

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