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.

SOW 2.0 General Scope of Work The Contractor shall furnish all labor, equipment, materials, supervision, and incidentals necessary to complete pavement repair and overlay. See EX-4 Maps, and EX-5 Photos.

Place of Performance:

Period of Performance:

60 calendar days from Notice to Proceed (NTP).

Construction NOT to take place before September 15th because of seasonal restrictions on construction during Marbled Murrelet nesting season.

SOW 3.0 Overall Objectives Restore pavement integrity, maintain ABA accessibility, and prevent negative environmental impacts.
