Flood Zone Information




ATTENTION SURVEYORS AND ENGINEERS:  FEMA NFIP has released a 2019 Edition of the Elevation Certificate. You may find the new edition at the link above or in the floodplain documents.

You may view your property along the Chena Slough with this comparison application showing the existing flood zones and proposed flood zones:  Chena Slough Preliminary Flood Maps​. The Chena Slough Preliminary Flood Insurance Rate Maps, Flood Insurance Study, and FIRM Database (shape​ files) can be viewed at FEMA's Flood Map Service Center. The 90-day appeal period of the preliminary maps closed on​ December 5, 2019. The Borough is waiting to receive the Letter of Final Determination to start the adoption process.

Title 15​ is the FNSB flood plain management ordinance. New construction or other development in the special flood hazard areas of the borough requires a Floodplain Permit​. One of the principal concerns is that new construction is elevated to the proper height in order to minimize flood loss.​  

Floods and flooding are the most common and costly natural disasters in the United States. Floods present a natural hazard that affects some borough residents year round and can jeopardize public health, safety and welfare.

The borough joined the NFIP in 1969 and remains committed to increasing the overall awareness of flood hazards in the FNSB and to improving permitting compliance for new construction occurring in the floodplain.

 It is important for the borough to continue monitoring new development in the floodplain by ensuring construction standards are met. Without such monitoring and regulatory oversight, the NFIP policies noted above would not be possible. In addition, mortgage financing would be difficult, if not impossible, for any properties located in a flood hazard area because of the lender’s requirement for flood insurance.
