    Management, Hazard Mitigation and Floodplain
    Management
  • Meeting/Exceeding Minimum NFIP Requirements
  • Updating Community Flood Damage Prevention
    Ordinance
  • Hazard Mitigation and Emergency Response Planning

44
Issue Discussion
  • Scale determination/panel numbering

45
Scale Determination
  • The scale of printed panels will be based on
  • The scale of the current FIRM panel covering
    flood hazards in the studied area
  • If the mapped area depicts a floodway narrower
    than 500 or a VE Zone
  • If any panel covering a municipality meets the
    criteria for 1500 scale mapping, the entire
    area inside the ETJ boundary of the municipality
    should be mapped at 1500

46
Scale Determination (Continued)
  • A FIRM panel will be printed for all areas where
    an SFHA is delineated, except panels that include
    only open water
  • FIRM panels will be consistent with the State
    land records 10,000 x 10,000 tiling scheme

47
Panel Numbering
  • Digital FIRMs will be produced in a statewide
    format, where multiple counties may be shown on a
    single panel
  • FIRM panels will be released by county, with a
    countywide FIS report
  • Process for numbering the panels and assigning
    one or multiple map numbers to a panel needs
    resolution

48
Issue Discussion
  • Studies Without Floodways

49
Studies without Floodways
  • Providing BFEs for areas studied by limited
    detailed analyses will result in additional
    expenses to property owners and communities
    involving
  • Surveys for elevation certificates
  • Studies to demonstrate that the cumulative effect
    of development within the floodplain will not
    increase the BFE more than 1 foot
  • Solutions to mitigate the burden of this last
    expense are being investigated

50
Issue Discussion
  • Future Conditions Mapping

51
Future Conditions Mapping
  • The State is investigating
  • Procedures that communities must follow to
    request, fund, and implement future conditions
    mapping
  • Data that the community must provide
  • Technical specifications for analyzing and
    mapping future conditions
  • FEMA is pursuing a necessary rule change in
    Federal regulations to map future conditions on
    FIRMs
