The Construction Zone Enhanced Enforcement Program (COZEEP) is a Statewide Interagency Agreement (contract) between Caltrans and the California Highway Patrol (CHP). It enables the Department to hire CHP officers and vehicles to patrol project construction zones. A PowerPoint presentation and the COZEEP Procedures guidance information for Resident Engineers may be found on the Headquarters Construction Program Intranet website.
COZEEP should be used to increase traffic enforcement above normal levels in situations where traffic problems are anticipated, to reduce the potential for traffic accidents within a construction zone, and to reduce traffic speeds to the posted speed limits. CHP Officers may be used to slow down or assist in stopping or directing traffic to enable necessary breaks in traffic for critical movements of the Contractor’s equipment and operations. During the erection or removal of bridge falsework over traffic lanes, or when traffic will be switched onto a detoured route are examples of when CHP Officers may be used to help control traffic.
The project engineer shall make an assessment of the need for COZEEP on every project that requires the contractor to close traffic lanes using cones or other channelizing devices and provide COZEEP for the following situations on freeways and expressways:
- All daytime or nighttime temporary closures of ALL lanes in the same direction of travel (Full Freeway Closures).
- Nighttime closures of two or more lanes on a freeway with three or more lanes of travel in the same direction.
All other closures shall be considered on a project specific basis. In general COZEEP is not necessary when only one lane is closed on freeways with four or more lanes in the same direction of travel.
Other “risk factors” that would indicate to the project engineer the possible need for COZEEP are listed in Chapter 2-215A (9) of the Construction Manual. This assessment shall be reviewed as part of the Project’s Safety Review and/or Constructability Review and may become part of the project’s Transportation Management Plan (TMP) and TMP estimate. The project engineer may specify specific construction operations where the use of COZEEP is mandatory.
The project engineer is also responsible to ensure that adequate COZEEP funds are included in the PID, and later in the project’s PS&E estimate as State Furnished Material. The design assumptions and estimate calculations should be included in the Resident Engineer’s pending file. The COZEEP cost estimate shall be based on the expected number of occurrences of the events needing COZEEP that have been identified. This should include an estimated number of COZEEP service hours that are then converted into a dollar cost. Contact the District COZEEP Coordinator for current costs. The project engineer may obtain assistance concerning COZEEP by contacting the District Traffic Operations Branch, the District Traffic Manager, the designated District COZEEP Coordinator within the Construction Division, or the Headquarter COZEEP Program Coordinator.
When estimating COZEEP hours, the CHP operating policies must be taken into account.
- CHP policy requires that between the hours of 10:00 PM and 6:00 AM there must be two officers in each CHP vehicle. (One CHP officer per vehicle is acceptable if a second officer and vehicle is also utilized in the near vicinity.)
- The CHP Memorandum of Understanding requires a minimum payment of four hours per officer.
- All times and mileage times are based on the Officer starting and stopping the detail at his/her regular duty station and must include travel to and from the project. The COZEEP Coordinator will provide current hourly costs for the project location, which shall include an allowance for mileage.
