III. ENVIRONMENTAL SETTING AND IMPACTSG. FIRE MANAGEMENT1.0 SETTINGThe Alameda Watershed is characterized by long, dry, warm summers and drought-resistantvegetation that is adapted to frequent natural fires. The Watershed is generally protected fromstrong, prevailing, western winds that would spread fires. However, the topography is quiteconvoluted, with several shallow slopes that are conducive to small fires. The climate, coupledwith a long history of grazing, has influenced an extensive cover of annual grasses. Grasslandthat is not regularly maintained by mowing or grazing promotes the likelihood of a fire, sincegrass is easily ignited.1.1 FIRE RESPONSE AND HISTORYThe Alameda Watershed is within the California Department of Forestry and Fire Protection(CDF) State Responsibility Area and, as such, is protected by CDF. The CDF station nearest tothe Watershed is the Sunol Station, located at 11345 Pleasanton-Sunol Road. For any fire that isnot immediately and easily suppressed by SFPUC staff, the CDF dispatches firefighters andcoordinates response to the fire. The CDF provides many other Watershed services, includinginspections, training, and emergency planning.The Alameda Watershed Fire Management Element provides a history of fire incidents withinthe Watershed, based on the recollection of SFPUC staff and CDF members. The fire historyinformation collected from staff was useful in identifying areas where fire management actionmay be warranted. The historical recollection indicates that there have been 33 fires within theWatershed since 1964, and 14 fires since 1990. Fires occurred principally along public roads,particularly Calaveras Road. The most common cause of fires was mechanical equipment,including motor vehicles and landscaping equipment. Approximately 20 percent of fires wereidentified as arson or occurred under suspicious circumstances. From 1966 to 1996,approximately 1,670 acres in the Watershed have burned. During that period, seven firesoccurred that burned 100 acres or more; the most recent fire of that magnitude occurred in 1980.The largest fire occurred in 1969 and burned approximately 400 acres. Wildfires have notthreatened private homes; however, one structure at the southern end of Calaveras Reservoirburned in 1993.1.2 ELEMENTS OF FIRE HAZARD AND PROTECTIONFour elements must be considered when addressing fire protection within the Watershed: firehazard, the resources at risk, fire behavior, and the fire protection system. Thus, although “firehazard” usually refers only to fuel complexes in regard to their ease of ignition and difficulty tocontrol, the overall issue of fire management within the Watershed requires consideration of theother three elements as well. In addition to these elements, fire ignition sources are consideredwhen addressing fire protection. Major ignition sources for wildfires are typically lightningstrikes and human actions (illegal campfires, arson, equipment use, discarded matches, andNOP 96.223E: Alameda Watershed Management Plan III.G-1 ESA / 930385January 2001
