About this file

These design drawings detail road repair work for the 3N17.4 Atmospheric River Damage project in the Angeles National Forest and San Gabriel Mountains National Monument. The documents include five site-specific plans (Base Bid Site 5 and Option Item Sites 1-4) with consistent construction elements: full depth reclamation, asphalt placement, embankment construction, rip rap installation, erosion control blanket application, and drainage structure/rolling dip installations. Specific quantities vary by site, ranging from 1,302 to 8,546 square feet of sawcut work, 24 to 155 tons of asphalt, and 1 to 3 cubic yards of rip rap, with flume lengths between 30-50 feet per drainage structure.

The project is part of a federal solicitation (127EAW25R0027) by the U.S. Department of Agriculture Forest Service, classified as a small business set-aside with a project magnitude between $250,000 and $500,000. Key dates include a site visit on July 21, 2025, and a Request for Information deadline of August 1, 2025, with the solicitation amendment dated August 4, 2025. Contractors are advised to carefully review Section L, Paragraph L.2 for proposal submission instructions and to submit any RFIs to the Contract Specialist, Tanya Torres.
