Montana Creek Road flooded August 20, 2011

Montana Creek Road floods August 20, 2011




  • The Biggert-Waters Act of 2012 increases flood insurance costs by reducing federal subdsidies on flood insurance. This is a multi-year phase bill that releases different changes over time.


NEW CBJ FLOOD MAPS & Study (dated August 19, 2013)

  • View Aerial Photograph Flood Maps

    • The blue areas represent the 100 year flood storm reach scenario. Buildings in blue areas are required to have flood insurance. The aerial photograph is dated 2006.


Quick Facts about new Flood Map & Study:

  • Overlay map onto aerial photograph for more accurate flood zone determination

  • Flood elevations and zones rely on 2001 LiDAR (Light Detection & Ranging) contour data

  • New map removes 272 buildings from Zones A & V (High Risk Flood Zone)

    • These owners might drop flood insurance

  • New map adds 226 buildings into Zones A & V (High Risk Flood Zone)

    • These owners will likely start paying for flood insurance

  • Errors in the maps can be more easily identified and then later corrected

  • New map replaces 1981 & 1990 maps.


According to FEMA, any building located in a high-risk flood zone (Zones A & V) that has a federally-backed mortgage must carry flood insurance. This insurance is not provided under your typical homeowner’s (or business, rental, etc.) insurance package. Lenders are required by federal law to ensure that a building in a high-risk flood zone carries flood insurance through the life of the loan.


Areas of the new flood map may contain errors or insufficient data for accurate mapping. If you believe the new flood map inadvertently puts your building/ property in a high-risk flood zone, you might be able to remove your building/ property through an approved map amendment or revision. Please contact Eric Feldt, CBJ Planner, (ph: 586-0764) to learn more about this opportunity.



  • To find out if you’re eligible for Grandfathering effects read this document and speak to your Insurance provider.


  • CBJ has compiled a short list of recommended fixes to the newly-adopted flood map. If you think something should be added, please contact Eric Feldt, ph: (907) 586-0764.



National Flood Insurance Program

The CBJ plans on adopting new flood maps and an insurance study that will not only provide better flood protection for the community, but will also meet the requirement of being part of the National Flood Insurance Program (NFIP). This voluntary program is governed by FEMA and allows communities to purchase flood insurance. Homeowners insurance usually does not cover flooding events.  In order to receive flood insurance, communities must participate in the NFIP and adopt and enforce special construction standards, flood maps, and insurance studies as tools for flood protection. You can read more about the National Flood Insurance Program at the following website:
