Every community has a unique geographic setting and people

Planning officials must understand local vulnerabilities in order to form appropriate adaptation strategies

• Well-documented disconnect between science and practice

18.

Improve transfer of relevant information from scientists to decision-makers

i.e. local SLRflood levelsnew flood hazard maps;

coastal cliff retreatsetbacks

Plan Santa BarbaraDraft Environmental Impact Report 19.

Perform SLR vulnerability assessments for two specific coastal communities in order to identify:

• Range of hazards

• Types of information needed for assessing vulnerability

• Range of available adaptation approaches

• Recommended adaptation strategies

20.

Create a guide for developing local mitigation plans

• Vulnerability assessments

• • Risk-based
