Flood Plain Development and Information
Regulatory changes to flood insurance rates and subsidized policies, will affect MAT-SU Borough property owners living in a Special Flood Hazard Area. See the attached Biggert-Waters Presentation for more information.
A Flood Plain Development Permit is required prior to rebuilding or any other development within a Federally Designated Flood Hazard Area.
If your property is located within the 100 year flood, there is at least a 1% chance each year the land may be subject to a "100 year" flooding event.
In an effort to reduce losses associated with these flooding events and reduce the amount of losses, the Federal Government, through the Federal Emergency Management Agency (FEMA), requires all structures to obtain Flood Hazard Insurance. To be eligible to receive Flood Hazard Insurance all new development must conform to the minimum standards of development as described in MSB 17.29 Flood Damage Prevention.
A complete application must include both the MSB Flood Hazard Development Permit and the Elevation Certificate. A Registered Engineer or Surveyor must complete the elevation certificate.
If you have any questions please contact the Permit Center or FEMA, Federal Emergency Management Agency, directly at http://www.fema.gov or 1-800-427-4661.
