Document Description
The Office of Maintenance Engineering requests environmental clearance for the Plans, Specifications, and Estimates (PS&E) package for Highway Maintenance (HM-1) Project EA 0Y9601 on SR-138 in the City of Palmdale (PM 46.7–50.0). The project proposes to apply a slurry seal, a thin layer of emulsified binder mixed with sand and small aggregate, to extend pavement life, with limited surface digouts up to approximately 0.33 feet in areas where cracking is too extensive for slurry treatment as confirmed by the project engineer. All work will occur within existing Caltrans right-of-way, and no shoulder backing, vegetation removal, grading, trenching, drainage work, or utility impacts are anticipated. Construction-area signs will not require ground excavation because they will be attached to existing poles or placed on contractor stands, consistent with nighttime and section-by-section construction operations. The project is fully state-funded, no relocations of utilities are anticipated, and no changes to impervious surfaces will occur.

Notice of Exemption
Exempt Status
Categorical Exemption
Type, Section or Code
Class 1 (14 CCR §15301(c))
Reasons for Exemption
The project qualifies for a CEQA exemption because it involves routine maintenance of an existing highway facility, including slurry seal and minor pavement digouts, with no expansion of use. All work occurs entirely within existing Caltrans right-of-way and does not require grading, vegetation removal, utility relocation, or other activities that could cause environmental impacts. Because the work only restores the existing roadway surface and does not increase capacity or alter environmental conditions, it meets the criteria of Class 1 (15301).
