NEWS!!!

  • Read about new Mendenhall River Flood Reports:

    2015 Juneau Jokulhlaup Inundation Report

    In 2015, the US Army Corps of Engineers (COE) partnered with the City and Borough of Juneau to study and map theoretical high water flooding along the Mendenhall River to better understand areas affected by Jokulhlaup flooding events. This flood study helps model where Jokulhlaup flooding might flow. With the recorded river gages and pictures during the 2014 Jokulhlaup, the COE was able to create new riverbank analysis to determine areas affected by future flooding events. Therefore, a Mendenhall River homeowner could determine which areas along the river could be flooded if river levels were to rise.

     

    2015 Meander Way bend Flood Protection Design Concept

    Also in 2015, the Natural Resources Conservation Service (NRCS)  studied a segment of the river along Meander Way to examine possible riverbank protection methods. Both of these studies will help understand how flooding will affect different parts of the riverbank, and provide a forecast of where flood waters might flow. The existing flood study (CBJ Flood Insurance Study) for the Mendenhall River shows areas that would flood during a 50-year or 100-year flooding event. This map doesn’t provide as much detailed information as the newer studies, however. But all play important roles for floodplain management.

  • Follow the Mendenhall Glacier Suicide Basin flood gauge.   

    • Read the 7/11/2014 Flood Warning PSA

  • Flood Insurance changes:

    • March 21, 2014 President Obama signed the Homeowner Flood Insurance Affordability Act of 2014. This repeals the Biggert-Waters Act of 2012.

    • 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.

    • Read this document to see if you’re eligible for Grandfathering insurance rates and speak to your Insurance provider.

    • Contact your Insurance Company about how these changes may affect you.


 

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

  • View Aerial Photograph Flood Maps (large maps)

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

 

Quick Facts about the new Flood Map & Study:

  • New map replaces previous 1981 & 1990 maps.

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

  • Flood elevations use 2001 LiDAR (Light Detection & Ranging) contour data.

  • 272 buildings removed from Zones A & V (High Risk Flood Zone).

    • These owners might drop/ reduce flood insurance.

  • 226 buildings added into Zones A & V (High Risk Flood Zone)

    • These owners will likely start paying for flood insurance

  • CBJ has compiled a list of recommended fixes to the new flood map.

    • Please contact Eric Feldt, ph: (907) 586-0764 If you think something should be added to this list.

Other important issues about the new Flood Map

  • No flood map is perfect. 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 a map amendment or revision.

    • Please contact Eric Feldt, CBJ Planner, (ph: (907) 586-0764) to learn more about this opportunity.

National Flood Insurance Program

In addition to adopting new flood maps and insurance study for increase flood awareness for the community, the CBJ also adopted new flood regulations to protect the community from flood damage.  By adopting those three eleements, the CBJ will continue to comply with the National Flood Insurance Program (NFIP). This voluntary program is governed by FEMA and allows communities to purchase flood insurance. Homeowners insurance 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: http://www.fema.gov/business/nfip/index.shtm.

 

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. If you're located outside of a high risk flood zone, you may purchase flood insurance. Floods can occur beyond the high risk flood zone line.
