Alaska Risk MAP Program

Community Risk MAP Studies

City of Seward

The City of Seward has been engaged in three recent mapping studies: a legacy Map Modernization Digital Flood Insurance Rate Map (DFIRM) study which was completed in 2013, a Physical Map Revision of the Japanese Creek Alluvial Fan, which is currently on hold pending , and the current Kenai Peninsula Borough Coastal Flood Study described in detail below.

Seward Physical Map Revision

This Physical Map Revision project included the detailed study and new DFIRMs for Grouse Creek, Bear Creek, Kwechak Creek, several Salmon Creek flows, Sawmill Creek, and Resurrection River.  The maps became effective on September 27, 2013.

Japanese Creek Physical Map Revision

This Physical Map Revision project includes a detailed study of the Japanese Creek Alluvial Fan.  Because the study area includes a levee that hasn't been accredited for National Flood Insurance Program (NFIP) requirements, the project has been placed on hold until FEMA finalizes its guidance for mapping non-accredited levees.

Kenai Peninsula Borough 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.

Study Scope

Specific to the City of Seward, the scope of work of the Kenai Peninsula Borough Risk MAP Study includes (see also the map below):

  • Ten miles of detailed coastal flood hazard analysis including the collection of storm surge (coastal hydrology) and overland wave height analysis (coastal hydraulics) of Resurrection Bay.
  • 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.
  • 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.
