Slurry Seal

The Office of Maintenance Engineering is seeking environmental clearance for the Slurry Seal project on State Route 138 in Palmdale, covering pavement miles 46.7 to 50.0. The project involves applying a thin slurry seal composed of emulsified binder, sand, and fine aggregate to prolong pavement life, with minor surface digouts of up to 0.33 feet in severely cracked areas as approved by the project engineer. All construction activities will remain strictly within existing Caltrans right-of-way, with no shoulder backing, vegetation removal, grading, trenching, drainage improvements, or utility disruptions expected. Construction signs will be mounted on existing poles or temporary contractor stands without requiring ground excavation, and work will be conducted at night and in sections to minimize disruption. The project is fully funded by state resources, with no utility relocations or changes to impervious surfaces anticipated. The solicitation is listed as a forecast with a posted date of July 17, 2026, and is managed by Caltrans District 7 – Los Angeles. Primary contact for environmental inquiries is Nestor Espinoza, Senior Environmental Scientist (Specialist), reachable via phone or email. The project is associated with reference number 2026070687 and is located entirely within the city of Palmdale, California. No set-aside classification, NAICS code, or vendor type is specified, indicating this is a pre-solicitation environmental review rather than an active procurement. The scope is narrowly defined to pavement preservation with no land use or environmental changes beyond the surface treatment itself.
