Public °ewe,,, Hearing Draft <br />an increased occurrence of extreme weather events. Such compounded impacts will <br />affect economic systems throughout the state, with likely ramifications in San Leandro. To <br />refrain from action is costly and risky; the California Fourth Climate Change Assessment <br />estimates that taking no action to address the potential impacts of climate change will <br />lead to economic losses of "tens of billions of dollars per year in direct costs" and "expose <br />trillions of dollars of assets to collateral risk." <br />As the climate continues to change and GHG emissions rise, climate change hazards will <br />continue to harm populations, infrastructures and buildings, economic drivers, and key <br />community services in San Leandro. The 2021 CAP includes goals, policies, and strategies <br />that will help reduce GHG emissions within the City and increase resiliency. <br />Figure 9 shows the SLR, flooding, and wildfire hazard areas in San Leandro, which are <br />expected to be the hazards that may have the greatest impacts on specific locations <br />within the community. <br />Bayshore Flooding <br />Low-lying coastal areas, such as the Oyster Bay Regional Shoreline, San Leandro Shoreline, <br />and Mission Bay are most susceptible to the effects of bayshore flooding. <br />Households within the Mulford Gardens, Marina Faire, and Heron Bay neighborhoods will <br />be affected by bayshore flooding. 28,29 Low-income households may live in structures that <br />are not water -proofed or built above the current 100-year flood elevation. Bayshore <br />flooding can damage homes, cause mildew and mold to grow, and destroy infrastructure. <br />The Mission Bay and Sandev mobile home parks are within the 2050 bayshore flooding <br />area.30 Mobile homes are generally less resilient than conventionally -built structures and <br />more susceptible to damage. <br />Additionally, many industrial centers are within the bayshore flooding area 31 Flooding can <br />interrupt economic activity and damage buildings or cause the release of harmful <br />chemicals used in industrial processes. <br />Multiple freight lines are within the bayshore flood areas in San Leandro. Coastal flooding <br />can damage track bed and ballast material, and the entire local rail system could shut <br />down, interrupting both freight and passenger rail services. Rail lines can be hardened and <br />protected through both natural and fabricated coastal protection infrastructure. However, <br />these options are expensive and may not always be feasible. Rail systems are also owned <br />by different entities, so consistent adaptation strategies may be difficult to implement and <br />fund.32 <br />Page 44 San Leandro 2021 Climate Action Plan <br />
