Pocket Canyon Slip Out Repair DO (EA 3X570)

Caltrans is undertaking emergency repairs to address a slip-out on eastbound SR-116 near Pocket Canyon in Sonoma County at post mile 15.40, caused by storm-related erosion that led to embankment collapse and soil displacement, with a tree stump further compromising the slope toe. The primary correction involves installing a 35-foot-tall interlocking sheet pile wall nine feet outside the fog line, with its top aligned flush with the existing embankment slope. Behind the wall, cellular concrete—used under a non-standard special provision—will serve as backfill, followed by imported borrow material compacted to at least 90% relative density. Cable railing will be constructed to ensure pedestrian safety, and full traffic control measures will remain in place throughout construction. A biological monitor must be present on-site during all activities to safeguard environmental resources. The project falls under a CEQA Class 1(d) categorical exemption for emergency repairs, with supporting documentation including a certified exemption finding, though a Notice of Exemption was not filed. No formal contract value, pricing structure, or detailed performance schedule is provided, and the designation as a forecast indicates a preliminary planning action rather than a fully awarded contract. The work is located entirely at the project site, with inspection and acceptance also occurring on-site under Caltrans oversight. No standard FAR clauses or federal procurement requirements such as UEI, CAGE codes, socioeconomic certifications, invoicing systems, or funding codes are referenced, and no Contracting Officer, COR, or COTR is identified. The project’s contractual obligations are embedded in technical specifications and environmental compliance conditions, with no formal submission deadlines or proposal formats outlined.
