Lake Mead National Recreation Area A04 statement of work: Fabricate and Install Gate at 8.0 Mile and Boxcar Cove Road

1. Background Lake Mead National Recreation Area (LAKE) is a U.S. national recreation area in Southeastern Nevada and Northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona. LAKE offers many recreational opportunities including boating, hiking, fishing, and both tent and RV camping. Because of these attractions, dispersed camping of RV’s and campers in unauthorized areas has become a growing concern. Specifically, the Government Wash area of LAKE has become inundated with disperse camping that has resulted in resource damage, littering of trash, and lead to major health and safety concerns.

This project will fabricate and install four metal gates at the area of Government Wash. The gates will be of metal pipe construction and will need to span the entire road to restrict access of vehicles during closures. In addition to the gate, attachment poles will be installed to lock the gate arms in the open position. Gate drawings have been attached to this document as a guideline for fabrication and installation.
