Slurry Seal

The California Department of Transportation, District 7, is seeking environmental clearance for Highway Maintenance Project EA 0Y9601, located on State Route 138 in the City of Palmdale, Los Angeles County, from post miles 46.7 to 50.0. The project involves the application of a slurry seal, consisting of a thin layer of emulsified binder mixed with sand and small aggregate, to extend the life of the pavement. In areas where cracking is too extensive for slurry treatment, the project includes limited surface digouts up to approximately 0.33 feet, as confirmed by the project engineer. All work will be performed within the existing Caltrans right-of-way and is fully state-funded. The project is categorized as a CEQA Class 1 exemption because it involves routine maintenance with no anticipated grading, vegetation removal, trenching, drainage work, or utility impacts. To avoid ground excavation, construction signs will be attached to existing poles or placed on contractor stands, supporting nighttime and section-by-section operations. The project will not result in any changes to impervious surfaces or the relocation of utilities. This forecast is associated with NAICS code 237310 and was posted on July 17, 2026.
