Findings:
Local Conditions:
Climatic:
Precipitation, relative humidity, temperature and wind. These local climatic
conditions affect the acceleration, intensity and size of fire hazard of a community.
Times of little or no rainfall, of low humidity, high temperatures and the winds
experienced in this area can have a tremendous impact upon structure fires especially
when buildings are close proximity to one another.
Geographic and Topographic:
Seismic location. Seismically, the City hae the San Andreas and Sargent-Berocal
faults running through the lower foothills and the Monta Vista fault system closer to
the valley floor area. The Hayward fault is just northeast of the City which would
have a major effect upon the City if it were to rupture. Adding to this threat is the
number of vehicles driven in the City is steadily increasing with commuters driving
to and through the city either to their homes, shopping and/or places of employment.
With so many vehicles on the road at any given time during the day can playa
major role on the response time of emergency services thus greatly increasing the risk
to property and life.
Local climatic, geographic and topographic conditions impact potential damage
to all structures from earthquake and subsequent fire. Therefore it is found to be
reasonably necessary that the Unifonn Fire Code and the State Building Standards
Code be changed or modified to mitigate the effects of the above conditions.
