12/06/2010 <br />delays along these roadway segments may be as long as 90 seconds.' These <br />delays result in an insufficient number of fire department resources arriving <br />sufficiently early to effectively control fires involving high -rise buildings, buildings <br />with untreated wood shake and shingle exteriors, and large interior areas not <br />having automatic fire - protection and life- safety systems. <br />Many of the new high -rise buildings and large building complexes have <br />structural, landscaping features, and designs which preclude or greatly limit any <br />approach or operational access to them by fire department apparatus. There are <br />many buildings to which access is limited to all but one side due to slopes, canals <br />and sloughs, levees, high- tension electrical transmission lines, fences, or other <br />buildings. When fire department apparatus cannot gain access to high -rise <br />buildings and large building complexes, it becomes necessary to conduct all <br />extinguishing and ventilating operations from the interior. It also requires that <br />much equipment must be carried for long distances from fire apparatus to the fire <br />location, which may be many floors above the ground. Such operations quickly <br />exhaust firefighters both in numbers and in stamina. This can result in delaying, <br />misdirecting, or making impossible - fire and smoke control efforts. <br />The aforementioned conditions support the imposition of fire - protection <br />and life- safety requirements greater than those set forth in the 2010 Edition of the <br />California Fire Code. <br />Finding 2: The strongest ground shaking probably will derive from <br />earthquake activity along the San Andreas, Hayward, or Calaveras fault. At least <br />one earthquake of magnitude 7 to 8 -1/4 can be expected during a one hundred <br />year period. In addition, several earthquakes of magnitude 6 to 7 can be <br />expected in the San Francisco Bay Region. Any of these earthquakes would <br />cause moderate to severe shaking throughout this region. The City of Redwood <br />City is particularly vulnerable to devastation should any such earthquake occur. <br />The potential effects of earthquake activity include isolating the City of <br />Redwood City from the surrounding area and restricting or eliminating internal <br />circulation due to the potential for collapse of highway overpasses and <br />underpasses, along with other bridges in the city, or an earth slide, and the <br />potential for vertical movement rendering surface travel unduly burdensome or <br />impossible. <br />Earthquakes of the magnitude experienced locally can cause major <br />damage to electrical transmission facilities which, in turn, cause power failures <br />while at the same time starting fires throughout the city. The occurrence of <br />multiple fires will quickly disperse existing fire department resources, thereby <br />reducing and /or delaying their response to any given fire. Additionally, without <br />electrical power, elevators, smoke management systems, lighting systems, alarm <br />systems and other electrical equipment needed for building evacuation and fire <br />' Redwood City General Plan Transportation and Circulation Technical Report, October 2008. <br />ATTY /RESO /RESO.2066 5 #15070 <br />111510 MUFF # 305 <br />
