01000-5

1.07 PROJECT/SITE CONDITIONS:

A. Background: The Lone Pine Campsite has been vacant due to damage done by the Archie Creek Fire back in 2020. Over the last few years efforts have been made to remove hazardous trees and limbs in and around the campsite. Vegeta-tion control efforts have been taking place; however, the rapid growth of under-story brush has impeded on most parts of the campground. Mobility in around the campsites could be impeded by large stumps that range from 12 to 48” in di-ameter. Over the years species like maple and elderberry shrubs have recovered well. In multiple locations maple shoots from cut stumps have produced clusters of maples in around the campsites. Preserve the maple clumps and clusters as best as possible working with the Lone Pine Campsite.

Not only has vegetation posed issues with maintenance of the campsite, but also, vandalism and theft of campsite accessories.

Utilities: There is currently no power or water service to the site; however, both utilities may be restored prior to the contract start date.

A buried cable line runs along Rock Creek Access Road. It is the contractor’s re-sponsibility to request utility locates prior to any earthwork. Additionally, the power supply to the Lone Pine Campsite pump house is provided by a power pole located on the south side of Rock Creek Access Road, adjacent to the ball field backstop.

1.08 A. All damage by Contractor’s activities shall be repaired by the Contractor at no cost to the Government.

B. Safety is paramount. Contractor is responsible for safety on the project site and shall take measures to maintain a safe area around the project site which is used by Government employees.

C. Landscape Protection: Protect all vegetation inside and outside work limits. All rutting caused by Contractor activities shall be filled and contoured to match ad-jacent areas and re-seed and mulch if applicable.

D. The contractor is responsible for locating and marking all existing buried utilities prior to the start of any work. If any buried utilities are found to conflict with the planned locations of posts or repair items, the Contractor shall notify the Con-

01000-6 tracting Officer’s Representative (COR) immediately. Appropriate relocation measures will then be determined in coordination with the COR.

E. Work Hours: Between the hours of 7:00AM and 8:00 PM.

F. Existing conditions and considerations:

Locations:

Refer to drawings for the proposed locations and existing site conditions.

1.09 DELIVERY, STORAGE, HANDLING AND HAULING

B. Storage: Provide temporary storage facilities for products. Storage shall comply with the manufacturer’s instructions. The storage area shall permit access for inspection and handling.

C. Handling: Load and unload products protecting them from damage.

D. Hauling: Comply with all legal and/or posted load restrictions when hauling ma-terials and equipment on public, private, and government roads to and from the projects.
