Public °ewe,,, Hearing Draft Persons experiencing homelessness are more likely to suffer respiratory infections, which are exacerbated by extreme heat. Persons experiencing homelessness and who are on medication are also at greater risk from extreme heat because some medications interfere with the body's ability to maintain a safe internal temperature during times of extreme temperatures. Households in poverty are less likely to live in air-conditioned buildings or those that have effective insulation, increasing their exposure to extreme heat. During extreme heat days, uninsulated or poorly -insulated homes may reach unhealthy temperatures. Households in poverty may not have access to medical services, which means that they are more likely to have medical conditions that can be exacerbated by extreme heat. Aging can impair muscle strength, coordination, cognitive ability, the immune system, and the ability to regulate body temperature, making elderly populations, especially those with limited income or mobility, at a higher risk of health impacts from extreme heat events. 42 Medications that seniors may be taking can also limit their ability to maintain a safe internal temperature. In general, seniors are more likely to suffer medical complications or death during extreme heat events than other members of the population. Extreme heat can regularly cause power outages due to a combination of mechanical failure of electrical grid equipment, heat damage to the wires themselves, and high demand for electricity as a result of cooling equipment, all of which causes stress on the grid. As extreme heat events become more frequent and intense, disruptions in service are likely to become more frequent. Although high temperatures in the City may not damage energy services, transmission lines going through inland areas can be damaged or not function properly due to extreme heat. Additional vulnerabilities include outdoor recreation, as people may be deterred from recreating outdoors in high temperatures, and aquatic and wetland habitats, whose water quality may decline as temperatures increase. Flooding As explained by the California Fourth Climate Change Assessment, California's water system is structured and operated to balance between water storage for dry months and flood protection during rainy seasons. Although climate change is likely to lead to a drier climate overall, risks from higher frequency, more intense rainfall events can generate more frequent and/or more severe flooding that upsets this managed balance between storage and protection. Climate change forecasts for the San Leandro region predict more intense rainfall events, more frequent or extensive runoff, and more flooding. According to Cal -Adapt, historically, intense rain events occurred an average of 2 times per year; they are projected to Page 52 San Leandro 2021 Climate Action Plan
