<br />8 <br />and cause catastrophic damage.9 Dam failure inundation maps pursuant to California Code Section <br />8589.5 are available from the Office of Emergency Services10. Although the dams are being seismically <br />strengthened and are outside the FEMA designated floodplain, it may be pertinent for San Leandro to <br />maintain a catastrophic emergency response plan for these conditions. <br />Even in a less catastrophic scenario, the considerable number of assets in areas with a one and 0.2 <br />percent chance of flooding in San Leandro make flooding a noteworthy threat to the city. Economically, <br />floods are costly. In addition to structural and contents damages caused by flood waters, the cost of <br />transportation delays, utility service outages and lost economic activity can be significant.11 City-wide <br />preparedness can help minimize these impacts and even benefit public health, as flooding and the <br />presence of standing water not only limit mobility by obstructing roads and disrupting utility service, but <br />also increase the chance of public exposure to water-borne pathogens, toxic algae or chemicals that <br />enter the water from spills.12 <br />As sea level rise encroaches on the marshlands that help protect the city from coastal floods, it will <br />become increasingly essential to minimize the contribution of land use change, site design and <br />impervious cover to water runoff, which may cause flooding to affect a wider area and occur more <br />frequently than historical records indicate. Exposed emergency and transportation assets such as Fire <br />Station 13 and the Bay Fair BART Station will be critical to account for in future planning. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />9 Draft City of San Leandro 2015 Local Hazard Mitigation Plan. <br />10 These maps have not been updated since the 1970s. <br />11 The Bay Area Council.
