Slurry Seal and RHMA on State Route 98

Caltrans District 11 is overseeing a pavement preservation and routine maintenance project on State Route 98 in Imperial County, specifically from 1.4 miles west of Imperial Highway to 0.5 miles east of Coyote Road near Ocotillo. The scope of work includes slurry seal, cold planning, the placement of RHMA-Type G, and the installation of rumble strips and shoulder backing. Additionally, the project involves restriping, applying pavement markings, and removing existing stripe lines at the central divider and right edge lines. Signage work consists of installing one new wood post sign and replacing two existing wood post signs. The project is identified by EA 11-2N302 and PID 1126000075, with environmental determinations signed on August 17, 2026. It is classified as a categorical exemption under CEQA Class 1 and a categorical exclusion under NEPA, as the work is considered routine maintenance of an existing public highway with no significant environmental impacts. Petra El-Shammas serves as the primary environmental scientist and lead agency contact for the project.
