This Coastal and Hydraulics Engineering Technical Note CHETN summarizes research efforts that have taken place since the 2008 fiscal year FY within the Coastal Inlets Research Program CIRP concerning asset management of coastal navigation channels. Specifically, the details concerning the conceptual basis and application of the Channel Portfolio Tool CPT are described. The CIRP work unit responsible for all of the efforts described herein is referred to as Coastal Navigation Portfolio Management CNPM. In response to a direct request from USACE-HQ, beginning in July of 2008 the CIRP started development of the Channel Portfolio Tool CPT. This web-based software uses the proprietary, dock-level tonnage database maintained by the Waterborne Commerce Statistics Center WCSC, part of the Corps Institute for Water Resources IWR Navigation Data Center NDC, for determining the extent to which dredged channel depths are utilized by commercial shipping. CPT provides an objective, consistent basis by which channels may be compared quickly to others for prioritization of Operation Maintenance OM funding, thereby providing improved justification for annual OM dredging budget items. The preliminary, proof-of-concept version of CPT received positive feedback in a briefing to examiners from the Office of Management and Budget OMB prior to the end of FY08. These same examiners had indicated previously to USACE-HQ personnel that improved justification such as that provided by CPT is a required precondition for increased outlays from the Harbor Maintenance Trust Fund HMTF, which carries a net balance of several billion dollars due to annual revenues exceeding outlays GAO, 2008.
