Assessments

• Culvert
• Traffic Barriers
• Signs
• Aggregate Sources
• Wetlands Mitigation Sites
• Tide Gates

Common Issues Needs

• Inventories
• A current and accurate Statewide inventory.
• Resources
• FTEs and to perform field inventories and
  ratings.
• FTEs and to maintain and update inventories on
  a regular basis.
• Automation Needs
• Databases, analysis tools and reporting tools.
• Standard data elements for minimal system and
  data integration
• Location descriptions (LRS), condition, type,
  install date, decommission date, etc.
• Statewide cooperation coordination of field
  data collection efforts
• Updated field data collection technology
  practices
• 3rd video camera, GPS equip., use of video log,
  contacting, partnering, evaluation of inventory
  schedules, etc.
• Integration w/ other asset data
• Access to - Construct Drawings, ITIS, Culvert,
  etc.

4
Culverts

• 1 Billion estimated value based on an estimated
  inventory of 50,000 culverts statewide.
• Many culverts are reaching the end of their
  design life.
• Failed culverts have major impacts on mobility
  and safety.
• There is a need to assess the condition of
  culverts statewide.
• Plans must be developed for the replacement or
  rehabilitation of these structures.

5
Traffic Barriers

• 350 Million estimated value.
• A current inventory had not been available and
  there is no repository for the data once
  collected.
• Some barriers may appear to be in fair or good
  condition but are no longer compliant with
  federal standards.
• There is a need to assess the condition and
  compliance of these assets statewide and maintain
  that inventory.
• Urban freeway and interchange areas are difficult
  and unsafe to field inventory.

6
Signs

• 197 Million estimated value (includes major and
  minor signs).
• Require frequent inspections and maintenance
  inventory.
• Federal retro-reflectivity standards require
  night drives to assess reflectivity condition.
• Several different data collection methodologies
  and databases in use.
• Susceptible to environment and collisions.

7
Aggregate Sources

• 1 Billion estimated value.
• Availability of sources could impact mobility and
  costs during projects, especially in some areas
  of the state.
• Lack of sources can delay the delivery of
  emergency repairs such as coastal washed out
  roadways.
• Essential to know the type and location of
  material source sites for projects.
• Access to accurate and complete data is key for
  state geologists.

8
Wetland Mitigation Sites

• Actual value is unknown. Estimated 74 ESA and
  Mitigation sites. Construction and PE costs range
  from 50,000 300,000 per site to construct.
• Mitigation sites need to be identified for
  project development avoidance purposes. Increased
  cost can be programmed for ahead of time.
• Even when we know where these sites are it takes
  considerable effort to avoid during routine
  maintenance activities.
• State and federal permits obtained for ODOT
  projects stipulate mitigation site performance
  standards and require a minimum of five years of
  monitoring.

9
Tide Gates

• 78,000 estimated value.
• Although there is no formal tide gate management
  program it has been determined that the efforts
  to currently maintain this asset are sufficient
  and have no immediate needs.
