Sea level rise is also expected to affect vulnerable populations along the coastthrough the immediate effects of flooding and temporary displacement andlonger-term effects of permanent displacement and disruption of local tourism.Of particular concern are populations that do not have the resources to preparefor, respond to, and recover from disasters. Impacts could include temporaryand/or permanent displacement, drowning and property damage, and coastalerosion harming recreational activities, tourism, and the tourism industry.Vulnerable populations living in institutional settings are disproportionatelyvulnerable during evacuations from disasters. For instance, Solano and Marincounties have a high proportion of elderly living in nursing homes that could beaffected (English et al., 2007).FloodingThe risk of flooding is highest for the inland, low-lying areas in the eastern part ofthe region. Reduced snowpack and increased number of intense rainfall events inthe Northern Sierra are likely to put additional pressure on water infrastructure,including the Delta levees, which are already vulnerable (DWR, 2011). Theseimpacts increase the chance of flooding associated with breached levees or dams(e.g., in the Sacramento-San Joaquin Delta). Flooding and damage to infrastructurecan put large populations in adjacent regions at risk (CDPH, 2008), including:• The elderly and children less than five years of age, who are isolated ordependent on others for evacuation.• Populations that may lack the resources or knowledge to prepare orrespond to disaster due to language or economic status, including havingaccess to transportation, which would allow them to escape flooding, at leasttemporarily.• Vulnerable populations living in institutional settings who are particularlyvulnerable during evacuations from disasters. For instance, Solano, and Marincounties have a high proportion of elderly living in nursing homes that couldbe affected (English et al., 2007).Public Health, Socioeconomic, and Equity ImpactsSome of the state’s highest percentages of impervious surfaces are in the urbanareas of the San Francisco Bay Area, increasing the potential impacts of heatislands (English et al., 2007). Santa Clara, Alameda, San Francisco, and ContraCosta counties rank fifth, sixth, ninth, and tenth in the absolute numbers of theelderly and children less than five years of age. These two populations are mostlikely to suffer from heat-related illnesses and heat events (English et. al, 2007).The highest risk of heat-related illness occurred in the usually cooler regionsfound in coastal counties and not in the Central Valley where the highest actualtemperatures were experienced (Gershunov and Cayan, 2008; CDPH, 2008).APG: UNDERSTANDING REGIONAL CHARACTERISTICS PAGE 34
Because of a lack of acclimatization, the largest mortality rate percent increasesin California are expected in coastal cities such as San Francisco (CNRA, 2009).Lodging and food services are among the top five employment sectors in Napa,San Francisco, and Solano counties, indicating that may be a significant numberof employees who work in the tourism industry/outdoors. Sea level rise mayimpact employees in the tourism industry. Air quality and heat events may impactoutdoor workers, including agricultural and dairy workers.The higher cost of living in some areas of this region (i.e. San Francisco, SiliconValley, Marin County) means low-income families pay a high percentage of theirincome on housing and transportation. Increases in food and energy costs mayimpact low-income residents.FireA slight increase in fire occurrence is projected for the region. This increaseis projected to be largest in the northeastern part of the region. Despitemoderate increases in fire risk, huge increases in fire damages are projected dueto high population in fire-vulnerable areas (Bryant and Westerling, 2009). Alongwith impacts associated with temporary and/or permanent displacement, longtermimpacts on the elderly and children under the age of five are of concern.Eye and respiratory illnesses due to air pollution resulting from wildfires, andexacerbation of asthma, allergies, chronic obstructive pulmonary disease (COPD),and other cardiovascular diseases, are likely to increase.AgricultureAlteration of temperature and precipitation regimes changes the seasons asexperienced by plants and animals. These changes are expected to affect thewine industry because the wine grape is a crop that requires a fairly narrowrange of climate conditions (Todorov, 2011). These changes might affect notonly wine grape growers, but also the businesses and residents dependent onthis industry. Communities reliant on the wine industry as an employment base,tourist attraction, or local economic base should closely collaborate with vintnerassociations and other local agricultural organizations to best understand the riskand support grower efforts to adapt. Communities also may need to plan for afuture in which wine grapes and associated activities make up a smaller part oftheir local economy.PAGE 35APG: UNDERSTANDING REGIONAL CHARACTERISTICS
