Overview

The planning team will conduct a risk assessment to determine the potential impacts of hazards to the people, economy, and built and natural environments of the community. The risk assessment provides the foundation for the rest of the mitigation planning process, which is focused on identifying and prioritizing actions to reduce risk to hazards. In addition, the risk assessment also can be used to establish emergency preparedness and response priorities, inform land use and comprehensive planning, and facilitate decision making by elected officials, city and county departments, businesses, and organizations in the community.

Task 5 presents a framework for conducting a local risk assessment. Many approaches to developing a risk assessment are possible, depending on available data, technology, and resources. Local risk assessments do not require sophisticated technology, but should be accurate, current and relevant. Some communities may choose to address a broader range of threats and hazards, or tie their hazard identification and risk assessment to other planning initiatives.

In our evaluation of 175 hazard mitigation plans, we identified the following best practices:
