GENERAL PROJECT INFORMATION

A. General

These Supplemental Conditions provide project-specific supplementary information and Supplemental Conditions to the General Conditions of the Agreement. These Supplemental Conditions are Contract Documents and address site-specific factors relevant to the execution of the Work for the Wildlife-friendly fencing on Conservation Grazing Units. These Supplemental Conditions shall supersede any conflicting General Conditions. Where a portion of the General Conditions is altered by these Supplemental Conditions, the unaltered portions of the General Conditions shall remain in effect. Under no circumstances does the information herein override any of the Terms and Conditions set forth in the Agreement, nor alleviate the Contractor from executing the work in strict conformance with the Contract Documents.

B. Project Description

The proposed Wildlife-friendly fencing on Conservation Grazing Units is in the Purisima Creek Redwoods, Cloverdale Ranch, Russian Ridge, and Skyline Ridge Open Space Preserves in San Mateo County, CA. Refer to Attachment B, Project Maps, for the project location. The purpose of Wildlife-friendly fencing on Conservation Grazing Units is to provide services for the construction of livestock fencing that is supportive of continued cattle management on four (4) District Grazing Units. Protected species are active in this region. The District’s qualified biologist consultant will provide the contractor training on-site to help the contractor avoid any potential interaction with protected species, as further described below in Article Four, paragraph J.

C. Site Information

Access: There are four (4) Project sites:

1. Lobitos Grazing Unit is located on Verde Road approximately 0.5 miles north of the intersection of Highway 1 and Verde Road. The Project property is accessed through a manual gate and an unimproved driveway. The property is shared with a grazing

D-3. Supplemental Conditions of the Agreement Page 4 of 8 operation. The project site is not accessible without prior District approval.
