California State Parks, CAL FIRE, and the Marin County Fire Department plan to resume a prescribed burn at Angel Island State Park starting as early as September 23, following a two-week pause.
The agencies began the burn on September 8 and completed 62 acres before pausing to discuss smoke impacts with the Bay Area Air Quality Management District. The full planned burn covers 260 acres.
Resumption depends on weather, air quality, and fuel moisture conditions. If conditions are not favorable for smoke dispersal, the burn will be rescheduled. Bay Area residents are likely to see smoke from 9 AM to 6 PM on burn days, with some visibility possible up to three days after ignitions.
The burn aims to reduce fuel loads in grasslands and coastal scrub on Angel Island, the largest island in San Francisco Bay. "We were able to burn 62 acres on the island with the fuels reduction that we've accomplished, reducing the chance of a catastrophic fire on the island," said Division Chief Sean Jerry, CAL FIRE Sonoma Lake Napa Unit, describing the initial effort.
Angel Island State Park will remain open during burn days. However, portions of the Ida Trail, Sunset Trail, and fire and perimeter roads will be closed for one to three days during and immediately after the burn. Access to the summit of Mount Livermore will also be restricted on some burn days.
