Municipality of Anchorage Risk MAP Study

The Municipality of Anchorage (MOA) was selected for a Risk MAP Study in Federal Fiscal Year 2013. 

Municipality of Anchorage Risk MAP Discovery Documents

On April 22, 2013, FEMA Region X staff, the State Risk MAP Coordinator, and other State of Alaska personnel met with MOA staff to conduct a Risk MAP Discovery Meeting. FEMA staff provided a brief overview of the Risk MAP Program, the Risk MAP process, and the products that could result from a Risk MAP study, such as the Changes Since Last Flood Insurance Rate Map (FIRM) Dataset, Contributing Flood Hazard Factors map, Depth Grids, standard regulatory products, and non-regulatory products.

The Discovery Meeting included a discussion of the MOA’s concerns for coastal flooding, earthquake, wildfire, critical facilities, avalanche, high wind, severe winter storms, and mitigation planning activities.

Based on the results of the Discovery Meeting, the MOA's RiskMAP project will consist of the following:

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.
