4.14. — Geohazards Technical Plan Executive Summary

4.14 - Executive Summary Overview

Key Steps

  • The CDOT Geohazards Program has a goal of reducing the risk of geological hazards on Colorado’s transportation system by implementing risk-reducing treatments on strategic highway segments and corridors. 
  • The Program’s investment strategy is to address geohazard risks that have a high likelihood of occurring and have potential high-dollar impacts when considering the consequences of safety, maintenance, and mobility.
  • A Geohazard Management System is used to track highway segments that have had a geohazard event. The system tracks hazard event types, road closure impacts, clean-up efforts, and costs. The inventory of recognized geological hazards throughout the state currently tops 3,000 hazards.

Handoffs and Coordination

  • The Material and Geotechnical Branch develops and maintains the statewide Geohazard Management System that inventories and identifies geohazard risks, identifies statewide projects, and directs project funding to the Regions.
  • The Geohazards Program tracks geohazard risks and performs mitigation design. Staff from the Program also respond to emergencies such as slope failures and rockfalls. 
  • Specialty contractors and consultants are utilized for highly specialized needs; for example rock scaling and aerial reconnaissance. 
  • The Regions participate in project selection, and manage and deliver mitigation projects within their jurisdictions. Maintenance crews regularly patrol highways with rockfall hazards and report areas where additional investigation is warranted. Maintenance crews provide immediate response to geohazard events. 

Key Asset Policies

  • Policy Directive 14, which sets the fiscally constrained performance target of 85 percent (90 percent unconstrained) of on-system segments at or above Level of Risk Grade B.
