Community Risk MAP Studies

Kenai Peninsula Borough

Recent Mapping Studies

Several mapping studies have taken place in the Kenai Peninsula Borough over the past several years, in additon to the Risk MAP Coastal Flood Study described in detail below.

Homer Spit

This Physical Map Revision project included 8 miles of revised coastal hazard analysis that included collection of storm surge data (coastal hydrology) and conduct overland wave height analysis (coastal hydraulics), in addition to computing wave runup.  The new Flood Insurance Rate Maps (FIRMs) became effective November 6, 2013.

Japanese Creek

This project includes the detailed study of 2.5 miles near the confluence of Japanese Creek. The study contains both an alluvial fan and a levee. The study scope inlcudes the development of topography, field survey, basemap, and hydrology, which have all been completed.  The project has been placed on hold until FEMA's new levee analysis and mapping approach has been finalized.

City of Seward Physical Map Revision

This legacy Map Modernization project included the modeling of Bear Creek, Grouse Creek, Kwechak Creek, Resurrection River, Salmon Creek, and Sawmill Creek and mapping within the City of Seward and adjacent Borough lands.  The new FIRMs became effective September 27, 2013.

Coastal Flood Study

FEMA and the State of Alaska are conducting a coastal Risk MAP Study in the Kenai Peninsula Borough that began in 2011.

The scope of work of the Kenai Peninsula Borough Risk MAP Study includes (see also the map below):

  • 28 miles of detailed coastal studies as well 21 miles of limited detail coastal studies. In addition, the scope includes approximately 11 miles of riverine studies in the following locations:
    • Cooper Landing – 4 miles of detailed study
    • Ninilchik – 2 miles of detailed study
    • Anchor Point – 5 miles of detailed study   
  • Preparation of a regulatory Flood Insurance Study (FIS) Report document to the Community. A FIS is a book that contains information regarding flooding in a community and is developed in conjunction with the FIRM. The FIS, also known as a flood elevation study, frequently contains a narrative of the flood history of a community and discusses the engineering methods used to develop the FIRM. The study also contains flood profiles for studied flooding sources and can be used to determine Base Flood Elevations for some areas.
  • Preparation of a regulatory Flood Insurance Rate Map (FIRM) map for all panels within the Community which identifies the Community's flood zones, base flood elevations, and floodplain boundaries. This map is used to determine where the purchase of flood insurance is required for properties with federally-backed mortgages. The preliminary FIS and DFIRM’s are scheduled to be released in Winter/Spring 2016.
  • Collect LiDAR in Spring/Summer of 2014. This data will be delivered to the community by Sept. 30, 2014.
  • All of the above datasets will be in the in the North American Vertical Datum of 1988.
  • The State and FEMA will provide guidance, feedback, coordination and technical support throughout the Risk MAP Project Life Cycle.
