This file consists of civil engineering plans and specifications for construction work at the North Rim of Grand Canyon National Park, prepared by HDR Engineering, Inc. and located in Denver, Colorado. The documents include detailed site plans, contractor staging and access plans, and comprehensive civil mapping symbology with materials, utility, and civil line legend information.

The plans depict the Norton Court Construction Camp and associated facilities, with specific delineation of limits of construction, contractor staging areas, temporary construction entrance locations, and equipment material storage zones. Key site features include two water storage tanks, the North Rim Water Treatment Plant, existing asphalt access areas, and designated areas for construction equipment parking and material laydown. The contractor is required to provide traffic control for National Park Service operations during construction activities and maintain access on all existing paved areas around the EMS building. All construction staging areas, temporary entrances, and work zones must be cleared of existing trees and vegetation, with quantities of approximately 200 tons of material to be removed and disposed of per specifications after construction completion. The plans specify that seasonal camping is acceptable at designated locations, full hookups are available May through October, and 3 of 5 available sites are designated for contractor use. Traffic access provisions and site restoration requirements are clearly marked on the mapping symbology sheets, which serve as the foundational reference for all construction-related civil engineering work on this federal project within Grand Canyon National Park.
