Fire Adapted 50: Phase 1a (Sly Park)

Fire Adapted 50: Phase 1a (Sly Park) is part of a series of wildfire fuels reduction projects to be completed through Fire Adapted 50, an innovative all-lands approach to increasing fire resiliency and fire adapted communities along the Wildland-Urban Interface (WUI) of the U.S. Highway 50 corridor. Phase 1a is located immediately adjacent to Phase 1 within Sly Park. The area is close to the King Fire Burn area which consumed 97,717 acres in the fall of 2014. The event threatened 12,000 residences, destroyed 12 residences and 68 other structures and damaged critical infrastructure including facilities, roads, bridges and electrical transmission and distribution lines (USFS Record of Decision (ROD) King Fire 9/15). The impact of the King Fire and prolonged drought have increased awareness about the susceptibility of communities and watershed resources to such catastrophic wildfires. As a result, CAL FIRE, in collaboration with federal, state and local agencies and private landowners have put forth a response in the form of a long term cohesive strategy to establish a more fire resilient WUI condition with a focus on the Highway 50 Corridor. Work on Phase 1a is currently on-going. A total of ~831 acres of land will be treated using mastication and hand thinning methods.
