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

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
