[1641] Global Change / Sea Level Change
Scientific paper
California’s coastal communities are vulnerable to the effects of rising sea levels, which may be 11 to 18 inches higher by 2050 and 23 to 55 inches higher by 2100 than in 2000. Local governments will need to plan for progressive inundation of low-lying areas, as well as increased erosion and storm damage. Although there is extensive research on climate change and sea level rise, local government staff is typically removed from this information and often lack the time or resources necessary for keeping up with the most recent information. Specifically, there is a disconnect between the latest science and the practice of coastal planners in dealing with sea level rise issues. Improving the transfer of relevant information and resources from scientists to decision-makers should encourage and assist local governments in their responses to this developing issue. Designing and implementing adaptation plans and developing policies for sea level rise are challenging. Each coastal community is unique in its geographic setting and demographics and therefore faces vulnerabilities that differ from those of other communities. Uplift and subsidence, for example, cause regional variations in the rate of sea level rise. Planning staff needs to understand the local impacts of sea level rise in order to take appropriate actions. Even when the potential threats are reasonably well understood, the gradual nature of sea level rise can make it hard to formulate, approve and implement policies that may not affect communities for decades to come. Fortunately, there are tools and resources available to assist planners. Several communities in California have recently completed climate change adaptation plans or are in the process of preparing such plans. However, these documents are not focused solely upon the specific issues associated with sea level rise. A study is underway to fill that void, which includes the development of an informative guide for local government agencies to use in the preparation of sea level rise vulnerability studies and in formulating adaptation plans. This project will identify: 1) the range of sea level rise hazards and issues facing California’s coastal cities and counties in the decades ahead; 2) the types of information or data needed for making vulnerability assessments; 3) the range of adaptation strategies available based upon the severity of the hazards and potential future impacts; and 4) appropriate response recommendations. Two communities have been selected for specific sea level rise vulnerability assessment studies, which involves working with agency staff from the selected communities to identify the current issues, concerns and problem areas. The experience and information gained from working with local government agencies will inform the guidebook’s development. The final products of this research include sea level rise adaptation plans for two local coastal communities as well as a guide to be made available to all of California’s coastal cities and counties.
