Coastal communities and the coastal zone are important areas, for a variety of reasons such as social, ecological and economic. These areas, however, are under increasing threat from both climate change and anthropogenic development. As the climate changes, the sea level is expected to rise causing instances of flooding as well as increased storm intensity triggering increased coastal erosion and coastal flooding along vulnerable shorelines. In order to measure areas of risk along the coastline and bayline of San Mateo County, a coastal vulnerability index (CVI) was used. The CVI used in this study was similar to one developed by researchers in South Africa who used it to apply a CVI to the KwaZulu-Natal province in South Africa. The CVI measured physical parameters such as beach width, distance to 20 meter isobath, distance of vegetation behind the back beach, dune width and percentage rocky outcrop in order to assess a relative vulnerability score for each sample site along the San Mateo County coast and bayline. In addition to the CVI being applied to San Mateo County, regional coastal stakeholders were interviewed in order to measure their own perception of risk relating to coastal vulnerability along the San Mateo County coast and bayline. Regional coastal stakeholders properly identified some of the most vulnerable sites in the area, however, there was a discrepancy in other locations where highly vulnerable sites were located but were not identified by stakeholders. For example, the area containing sites numbered 1-39 had several spots of high vulnerability, however, very few stakeholders identified these areas. One of the sites that was commonly identified is located in between sample sites 46 and 47 in Half Moon Bay, California. The primary factors relating to vulnerability at this site include: the lack of dunes, lack of vegetation behind the back beach, a narrow beach width, and a lack of rocky outcrop. The distance to the 20 meter isobath is the only factor that does not rank this site as highly vulnerable. This study also provides a suggested management plan for the site.
Key words: Coastal Vulnerability Index (CVI), coastal erosion, coastal flooding, sea level rise, San Mateo County, California, Integrated coastal zone management.
