HM4-TMS HAR Equipment Replacement

The HM4-TMS HAR Equipment Replacement project is a forecast solicitation issued by the California Department of Transportation (Caltrans), District 3 - Marysville/Sacramento, on August 11, 2025. The primary objective is to replace outdated or non-functional Highway Advisory Radio (HAR) equipment to ensure the systems meet current technology standards and remain operational. The scope of work covers multiple locations across seven California counties, including Butte, El Dorado, Nevada, Placer, Sacramento, Solano, and Yolo. The project is classified under a Class 2c categorical exemption under the California Environmental Quality Act (CEQA), as it involves the replacement of existing structures on the same site with substantially the same purpose and capacity, resulting in negligible expansion. While the project is listed as a forecast with NAICS code 334510, specific financial details, evaluation factors, and formal contract clauses are not yet defined. The lead agency contact is Jennifer Jones, Environmental Planner, and the project is governed by Public Resources Code Sections 21083 and 21110.
