In Los Angeles, however, partners and stakeholders identified additional climate risks to incorporate, such as erosion and wildfire.ġ) Developed location-specific indicators for social, structural, and natural resource vulnerability Ģ) Identified local coastal risks of most concern and their impacts ģ) Intersected base condition vulnerabilities with identified coastal risks andĤ) Identified areas of high risk and high vulnerability for further analysis. In both applications, local stakeholders identified coastal and stormwater flooding as risks of highest priority. The Framework was developed for the Town of Oxford and Talbot County in Maryland, and was then extended to NOAA’s Choptank Habitat Focus Area in the Chesapeake Bay region. Integration of a wide range of vulnerability and risk profiles enables users to more easily understand the complexities of overall vulnerability and risk within their region. The Framework measures social, structural, and natural resource vulnerability and intersects those with coastal risks to identify areas of high vulnerability and high risk. To address vulnerability to climate effects and coastal risks in the study region, we first adapted NCCOS’s Integrated Vulnerability Assessment Framework to Los Angeles County. ![]() Los Angeles County coastal homes at risk from coastal flooding and erosion. This study examined these complexities across the County to inform decision making within the region. Similarly, Los Angeles County faces extreme variation in social and economic factors, including disparities in income, education, and employment opportunities. The County is impacted by a variety of threats, such as bluff erosion, sea level rise, wildfire, saltwater intrusion, wave-driven run up, earthquakes, and tsunamis, as well as concerns over water availability, water quality, and air quality. As one of the nation’s largest and most populated counties, with 4,084 square miles and approximately 10 million residents, its geography, ecology, and communities are highly variable, as are its climate impacts and risks. Los Angeles County is a highly complex and diverse area. This work provides information to better protect, advance, and manage climate change impacts within local communities. To address these and other changing coastal risks in Los Angeles County, NCCOS researchers extended their Integrated Vulnerability Assessment Framework to this densely populated and highly urbanized region, coupled with further spatial and economic analyses. Coastal communities are increasingly vulnerable to climate effects, such as sea level rise and coastal erosion.
