I. BACKGROUND ON THE GOVERNMENT’S REQUIREMENT:

Consumnes River Preserve (CRP) is located within California’s Central Valley, north of the city of Stockton and south of the city of Sacramento. The Cosumnes River Preserve consists of over 50,000 acres of wildlife habitat and agricultural lands owned by seven land‐owning Partners. The Preserve is centered along the Cosumnes River, its floodplains and riparian habitat. This habitat is buffered by a variety of agricultural operations. The Preserve provides numerous social, economic, and recreational benefits to local communities and to people residing in the larger Sacramento and San Joaquin areas. The habitat supports wildlife, including birds that migrate throughout the Pacific Flyway.

The CRP Visitor Center features a publicly accessible double vault toilet, located within an interior island of the public parking lot. Sidewalk providing access to these facilities requires repairs to restore functionality, improve safety, and preserve the facility for future use. Work includes demolition, disposal, and replacement of deficient sidewalk sections to maintain the facilities in a safe working order and meet ADA accessibility requirements. This Statement of Work, along with supporting information, is intended to define the tasks and expectations for work to be accomplished under this contract.
