SOW 1.0 Background on the Government’s Requirement BLM Northern California District requires pavement rehabilitation of the Elk River Trail within the Headwaters Forest Reserve. The trail provides critical access to recreation, ecological, and historic resources and must maintain ABA accessibility standards.

The trail exhibits cracking, localized pavement failure, and shoulder degradation, see EX-

5 Photos. Without repair, deterioration will accelerate, resulting in unsafe conditions and potential sediment impacts to nearby federally listed coho salmon habitat.

This project includes targeted full-depth repairs, surface preparation, asphalt overlay, and shoulder backing.

A pavement tie-in at the Headwaters Education Center (HEC) Barn driveway requires a smooth, ADA-compliant transition between new overlay and existing pavement surface.
