01/24/2011 delays along these roadway segments may be as long as 90 seconds. These delays result in an insufficient number of fire department resources arriving sufficiently early to effectively control fires involving high -rise buildings, buildings with untreated wood shake and shingle exteriors, and large interior areas not having automatic fire- protection and life- safety systems. Many of the new high -rise buildings and large building complexes have structural, landscaping features, and designs which preclude or greatly limit any approach or operational access to them by fire department apparatus. There are many buildings to which access is limited to all but one side due to slopes, canals and sloughs, levees, high- tension electrical transmission lines, fences, or other buildings. When fire department apparatus cannot gain access to high -rise buildings and large building complexes, it becomes necessary to conduct all extinguishing and ventilating operations from the interior. It also requires that much equipment must be carried for long distances from fire apparatus to the fire location, which may be many floors above the ground. Such operations quickly exhaust firefighters both in numbers and in stamina. This can result in delaying, misdirecting, or making impossible - fire and smoke control efforts. The aforementioned conditions support the imposition of fire- protection and life- safety requirements greater than those set forth in the 2010 Edition of the California Fire Code. Finding 2: The strongest ground shaking probably will derive from earthquake activity along the San Andreas, Hayward, or Calaveras fault. At least one earthquake of magnitude 7 to 8 -1/4 can be expected during a one hundred year period. In addition, several earthquakes of magnitude 6 to 7 can be expected in the San Francisco Bay Region. Any of these earthquakes would cause moderate to severe shaking throughout this region. The City of Redwood City is particularly vulnerable to devastation should any such earthquake occur. The potential effects of earthquake activity include isolating the City of Redwood City from the surrounding area and restricting or eliminating internal circulation due to the potential for collapse of highway overpasses and underpasses, along with other bridges in the city, or an earth slide, and the potential for vertical movement rendering surface travel unduly burdensome or impossible. Earthquakes of the magnitude experienced locally can cause major damage to electrical transmission facilities which, in turn, cause power failures while at the same time starting fires throughout the city. The occurrence of multiple fires will quickly disperse existing fire department resources, thereby reducing and /or delaying their response to any given fire. Additionally, without electrical power, elevators, smoke management systems, lighting systems, alarm systems and other electrical equipment needed for building evacuation and fire 1 Redwood City General Plan, Transportation and Circulation Technical Report, October 2008.
