Alaska Risk MAP Program

Community Risk MAP Studies

Municipality of Anchorage Risk MAP Study

FEMA and the State of Alaska are conducting a Risk MAP Study in the Municipality of Anchorage (MOA) that began in 2013.  

Municipality of Anchorage Risk MAP Discovery Documents

The following non-regulatory activities are currently underway:

Avalanche Risk Methodologies

MOA has an existing analysis of avalanche risk; however a more detailed analysis is desired. Information will be provided about assessments and methodologies used by other communities. Available data will provided that can support an updated avalanche risk assessment.

Earthquake Risk Assessment

As a part of preparation for the Alaska Shield Exercise in 2014, FEMA Region X collected building stock and infrastructure data from MOA.  As part of the Risk MAP project FEMA will create a detailed earthquake risk assessment using Hazus, a loss estimation software. The results will be given to MOA for use in prioritizing mitigation actions and targeting community outreach.  FEMA will also review the existing Downtown Seismic Risk Assessment to determine if any assistance or resources can be provided to mitigate the identified risks.

Flood Study Priorities

Flood study needs and priorities for the flood sources impacting MOA will be documented in a report that FEMA can use as funding becomes available for additional riverine flood insurance studies. The report will address the following topics:      

  1. Vertical Datum – document the steps needed for MOA to transition to the use of NAVD88 and any outside assistance needed to make the transition.
  2. LiDAR – document existing LiDAR and other topographic data, including details on data quality, and determine areas where future LiDAR acquisition is desired.
  3. Re-delineation – document issues with previous re-delineations of Special Flood hazard Areas.
  4. New Flood Studies – document flooding sources in MOA and prioritize areas for new flood insurance studies.
  5. Levee Policy – document levees in MOA and the impact on flood studies based on FEMA’s Levee Policy.

Wildfire Outreach

Future outreach opportunities will be determined and further issues explored related to wildfire risk and insurance. 

Outstanding/Pending Flood Studies

In addition to the new Risk MAP study discussed above, there are two outstanding/pending flood studies in the MOA:

  • A Physical Map Revision incorporating new studies for Furrow and Girdwood Creeks in 2006. This project is a legacy Map Mod project which is currently on hold due to the change in FEMA’s levee policy.
    The new levee analysis and mapping approach FEMA has developed is currently in the 45-day “Public Review and Comment” Period which started on December 15, 2011.
  • Under the Risk MAP Program, FEMA commenced a Physical Map Revision/LiDAR Acquisition project comprised of a mix of detailed studies and redelineations, including a detailed study of Eagle River and re-delineation of Girdwood flooding sources and of Little Campbell Creek. This project has been suspended due to numerous concerns the Municipality had with technical and procedural aspects of the project, including the vertical datum and the scope of the project study. FEMA plans to continue the project once these concerns are addressed and resolved.
