Public Awareness Challenges
Corps invests hundreds of millions of dollars annually in maintenance of our
hidden
national waterway infrastructure.
National dependence upon this vital infrastructure has not translated into full public awareness.

CPT Background
The USACE Navigation Mission:
to provide safe, reliable, and efficient waterborne transportation systems (channels, harbors, and waterways) for the movement of commerce, National security needs, and recreation.

CPT Background
•
CPT is a web-based decision-support tool which helps convey the importance of Corps dredging activity to the efficient movement of maritime commerce.
– –
Corps-only version: https://cpt.usace.army.mil
Public version: TBD, coming soon
•
Started in late FY2008, with two primary objectives:
–
Provide consistent, objective prioritization of Corps Operations and Maintenance (O&M) dredging activities for allocation of Harbor Maintenance Trust Fund (HMTF) outlays
–
Provide Corps personnel with improved access to and understanding of the data provided by the Waterborne Commerce Statistics Center (WCSC) ERDC-CHL 4
Deep-draft Navigation O&M
• • •
350+ HMTF-eligible navigation projects are actively maintained Wide variation in project spatial extent and level of use USACE is historically a decentralized organization…

Waterborne Commerce Data
• The Corps’ Waterborne Commerce Statistics Center (WCSC) collects and collates data from several sources concerning commercial use of US waterways.
– Dock-level, origin-to-destination routing (Corps-use-only) – Includes tons, commodity types, vessel counts, drafts – Aggregated data already published at project level – Corps planning community has used WCSC data to support harbor deepening projects and inland studies
http://www.ndc.iwr.usace.army.mil/wcsc/wcsc.htm
• Corps Operations community has not consistently used this data beyond project-level tonnage and ton-mile metrics for O&M budget development.

Spatial Join to Waterway Network
•
CPT spatially joins the docks in the WCSC database with the respective sub-reaches.
•
Full network connectivity, ensuring that all transited channels are appropriately credited.
•
Shortest-path routing used for domestic and inland river traffic transiting multiple projects.
ERDC-CHL 8
Depth Utilization Analysis
CPT can generate depth-utilization profiles showing the distribution of cargo across the range of maintained depths for any system of navigation channels.
CPT then compares these tonnage-draft profiles to the segment controlling depths resulting from present shoaling conditions.

Navigation Systems Defined
•
CPT provides a flexible, accessible means of defining
systems
•
maintained channels.
Corps decision makers can now see the extent to which these of navigation systems are utilized by commercial shipping.

Navigation Systems Analysis
•
The Waterborne Commerce data via the CPT gives the Corps a straightforward O&M budget formulation capability and allows for more advanced navigation systems analysis.
•
These efforts are drawing interest from other Federal agencies (e.g. CMTS) as well as the Transportation Research Board (TRB).
