Best Available Information BAI is existing FIRM, FIS, FHBM/FW Map OR draft or prelim info supplied by FEMA or other source Must follow FEMA technical standards and accuracy Tool to reduce community flood risk Use in community planning, engineering, development review, permitting and emergency management functions First check local codes and ordinances to see how it can be used (may need to be adopted) Can be used to submit LOMA and LOMR-Fs. FEMA will determine accuracy determine eligibility GIS data will be made available In a nutshell.

State Strategy & Implementation Outreach Quarterly Meetings or Quarterly Newsletters Dedicated Website Review Meeting Public Outreach Assistance Press Release Public Meetings Templates Not Regulatory Map Not part of this scope No Due process and appeal period-FEMA Map update Please mention that this will be best available data for communities to use until it becomes effective. Local communities can choose to adopt and regulate to it. Also, since the goal is make this an effective FEMA map, a public appeal period will occur at the next phase. Also we welcome comments from communities and following the typical FEMA map process, will work thru FPA as our POC.

Communication and Outreach http://www.coloradohazardmapping.com/ We can give you the tools and show you how to use them Increase the understanding of natural hazard risks associated with living, working, and doing business Encourage growing numbers of communities, businesses, and individuals to adopt new methods for risk mitigation and resilience Collaborate, mitigate and enhance communities, ecosystems, and economies in order to become more resilient to natural hazards
