background
Background
  • The National Flood Insurance Program was established by Congress in 1968 to:
    • Protect lives and property
    • Reduce financial burden for flood damage assistance
  • Federal Emergency Management Agency (FEMA) administers the NFIP
  • Almost 50,000 communities in the U.S. participate in the NFIP
  • Over 98 percent of California’s communities participate in the NFIP

agency roles community
Agency Roles: Community
  • Adopt floodplain management regulations that meet or exceed NFIP standards and requirements
  • Provide information to residents on flood hazards, floodplain map data, flood insurance and proper construction methods
  • Monitor floodplain development by issuing permits and conducting inspections
agency roles state
Agency Roles: State
  • Ensure that communities have the legal authority necessary to adopt and enforce floodplain management regulations
  • Establish minimum state regulatory requirements consistent with the NFIP (model FPM ordinance)
  • Provide technical and specialized assistance to local governments

hazard identification
Hazard Identification
  • FEMA conducts a Flood Insurance Study (FIS) to appraise a community’s flood problems
    • Final report—written text, stream profiles, figures, tables, etc.
    • Flood Insurance Rate Map (FIRM)—shows of flood hazard areas, flood insurance risk zones (ex: A, AE, V, or VE), base flood elevations, floodways and other related information
hazard identification15
Hazard Identification
  • Base flood
    • A flood that has a one-percent chance of being equaled or exceeded in any given year
    • Referred to as the “100-year” flood
  • Base floodplain
    • The land covered by the floodwaters of the “base flood”
    • Referred to as the “Special Flood Hazard Area” (SFHA)
  • Base flood elevation (BFE)
    • The water surface elevation of the base flood

fpm regulations
FPM Regulations
  • To participate in the NFIP, a community must:
    • Adopt and enforce FPM ordinance
    • Require permits for floodplain development
    • Estimate flood elevations that were not determined by FEMA
    • Require residential structures to be elevated at or above the 100-year flood elevation (BFE)
    • Conduct field inspections and cite violations
    • Establish variance procedures
    • Advise FEMA when map updates are needed

Multi-Hazard Planning
  • Disaster Mitigation Act of 2000
    • Established a pre-disaster hazard mitigation program
    • Established new requirements for the national post-disaster Hazard Mitigation Grant Program (HMGP)
    • States and communities must have an approved multi-hazard mitigation plan in place before receiving post-disaster HGMP funds

Improving NFIP Effectiveness
  • Despite successes, there are concerns with the NFIP:
    • It only sets “minimum” standards
    • It focuses upon how to build in floodplains vs. how to minimize future damage caused by development
    • It ignores changing conditions
    • It ignores adverse impacts to existing properties
    • It undervalues natural floodplain functions and societal values
improving nfip effectiveness28
Improving NFIP Effectiveness
  • Go beyond “minimum requirements”
  • Join the existing Community Rating System
  • Adopt ASFPM “No Adverse Impact” Strategies
  • Integrate FPM planning with community general planning process

Community Rating System
  • Reduces flood insurance rates for communities that implement activities above NFIP minimum standards
  • Maximum premium reduction—45%
  • 61 CA communities participate in CRS
  • CA 2004 premium savings--$9.7 million

Community Rating System
  • CRS categories of activities
    • Series 300: Public information
    • Series 400: Mapping and regulations
    • Series 500: Flood damage reduction
    • Series 600: Flood preparedness
  • More CRS info:

to summarize
To Summarize…
  • The NFIP sets minimum FPM standards
  • Communities are encouraged to go beyond minimum standards
    • For example, the state of California recommends that lowest floor be elevated TWO feet above the base flood elevation
    • See Model ordinance and other NFIP training at:

www.fpm.water.ca.gov

  • Join the Community Rating System
  • Adopt No Adverse Impact strategies
