NCMP PROGRAM

Only federal coastal mapping program producing regional operational data along the coast of the U.S. on a reoccurring basis to support regional engineering activities like regional sediment management, comprehensive coastal studies, remote inspection of coastal structures, post-storm coastal impact assessment, and mapping of threatened and endangered species and habitats

PROBLEM

NCMP was originally formulated for CONUS Alaska has more coastline than CONUS and has critical need for coastal mapping data to manage risk due to hazards including coastal erosion, storm flooding, landslides, tsunamis and earthquakes

May 2021

APPROPRIATION

Agreement includes $3.8M for Arctic coastal mapping needs not met by existing mapping programs due to gaps caused when mapping agencies distinguish between land mapping and water charting USACE shall use these funds to prioritize, coordinate and conduct Arctic coastal mapping operations, data processing, product development and data dissemination to identify and meet priorities in the Arctic region USACE works closely with the Alaska Mapping Executive Committee, Alaska state, and relevant federal agencies to ensure that mapping efforts are coodinated and adhere to the Alaska Coastal Mapping Strategy

NATIONAL COASTAL MAPPING PROGRAM (NCMP): ARTIC MAPPING


FY18 NATIONAL COASTAL MAPPING PROGRAM (NCMP): ARTIC MAPPING

NCMP surveyed a pilot project in Homer, Alaska, in 2018 using an aircraft equipped with a Coastal Zone Mapping and Imaging LiDAR that was transiting through the state

FY19

NCMP coordinated with USACE's Alaska District, Alaska Department of Natural Resources and the Alaska Coastal Mapping Strategist to identify areas in critical need of topobathy data for navigation project management, coastal erosion studies, and storm and tsunami flood modeling NCMP was able to use an aircraft transiting through Alaska on its way back from work in the Pacific, eliminating mobilization costs The long-range aircraft was able to survey 12 projects throughout Alaska in three weeks

May 2021

FY21 PLANS

NCMP will perform coastal mapping operations in Alaska for approximately two months NCMP is coordinating mapping requirements with USACE Alaska District, the Alaska Coastal Mapping Strategist, and the Alaska Department of Natural Resources Coastal Hazards program manager Requirements are driven by USACE project needs, a statewide prioritization and emerging data needs related to landslides in the southeast Establish a coastal mapping collaboration with the University of Alaska Fairbanks (see image to the left)
