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 (OM) 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)

Deep-draft Navigation OM

• 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
• Corps Operations community has not consistently
  used this data beyond project-level tonnage and
  ton-mile metrics for OM 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.

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 of maintained channels.
• Corps decision makers can now see the extent to
  which these navigation systems are utilized by
  commercial shipping.

Navigation Systems Analysis

• The Waterborne Commerce data via the CPT gives
  the Corps a straightforward OM 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).
