The fire broke out around 8:30 pm in the 1200 block of W 4th St near L St. The fire was estimated at 1-acre in size. By 9:10 pm, the fire was estimated at 9:30 am deep in vegetation and tulles. Structure protection was also dispatched to the Marina and Smiths Landing after embers were observed landing on boats.
As of 10:09 pm, the fire was growing. Its unclear how the fire started and was anticipated to burn itself out over the next several hours.
The Antioch Police Department and AMR also responded.
CONFIRE UPDATE
Just after 8:20 p.m., Contra Costa Fire responded to reports of a vegetation fire burning near the waterfront and railroad tracks in Antioch. Initial callers reported flames in grass.
The first arriving crews encountered an approximately two acre wind-driven vegetation fire burning in grass, brush, and tule vegetation near the railroad corridor and marina area. Due to active spotting, difficult access, and nearby infrastructure concerns, a second alarm vegetation response was requested. Firefighters worked on both sides of the railroad tracks while coordinating with BNSF Railway to temporarily stop rail traffic for firefighter safety. Crews established multiple divisions for fire attack, structure protection, and access operations as the fire spread through marsh and wetland areas.
Additional resources, including wildland engines, hand crews, water tenders, and Contra Costa Fire’s fire boat, responded to support suppression efforts and protect nearby marina structures.
Power lines running through the fire area also created additional hazards during suppression operations. PG&E responded and confirmed high-voltage lines in the area were de-energized while crews continued firefighting operations. Firefighters successfully stopped forward progress of the fire at approximately three to four acres, with crews remaining on scene for several hours conducting extensive mop-up operations in difficult-to-access tule and marsh terrain.
