1. Project Background

1.1. Lake Mead National Recreation Area (LAKE) is in the process of enhancing its flood warning sign system at the Willow Beach Area - Willow Beach, Arizona. Willow Beach is one of three developed areas on Lake Mohave comprised of a 67-mile-long freshwater reservoir on the Colorado River. Willow Beach is one of the most used areas of Lake Mohave with about 400,000 visitors annually. Because of its susceptibility to flash flood hazards, the facilities in the Willow Beach area have been closed due to safety reasons. As a result, visitation has declined by over 50% to around its current level of 200,000 visitors annually. Previous projects have undertaken the effort to re-establish visitor facilities which included the completion of the Hoover Dam bypass which has since improved travel time and convenience. These project improvements have enlivened the demand for facilities and services at Willow Beach by residents and visitors.

Cottonwood Cove area covers from Mile 12 on Lake Mohave (the South end of the basin) to approximately Mile 40 (Nelson’s Landing.) The Canyon area covers areas to the North and the East area on the Arizona side. The Cottonwood Cove developed area is designated as “Historic,” as many of the buildings are Mission 66 construction.

1.2. A previous SNPLMA project of the Willow Beach and Cottonwood Cove facilities consisted of the installation of structural flood protection measures; construction of a new campground, picnic area, trails, interpretive displays, restrooms and other associated facilities and relocation of NPS facilities out of the flood plain.

1.3. Despite efforts of trail reconstruction, road improvement, regrading of slopes in the campground, the Willow Beach area is still susceptible to flash flooding. A levee structure was installed in early 2019 at the Cottonwood Cove area to address flooding. There is currently flash flood sign system with lights located down at and around the Willow Beach Marina and Visitor Facilities as well as in the Cottonwood Cove area. The goal of this project is to install a flash flood warning sign at the Willow Beach entrance station that will provide adequate time for visitors to be warned of an active flash flood and to refrain visitors from traveling down the road to the area that is susceptible to wash outs. Also, establish maintenance support of the flash flood warning systems for both Willow Beach and Cottonwood Cove sites.

2. Period of performance and Location

2.1. Work shall be completed within 45 days of contract award. Work will be conducted at Willow Beach, Lake Mead National Recreation Area, Mohave County, Arizona and Cottonwood Cove Resort & Marina, Lake Mead National Recreation Area, Searchlight, Nevada

3. General

3.1. This project will accomplish the construction, placement, configuration and deployment of a flash flood warning sign directly across from the existing sign that is located on the left hand side of the Willow Beach access road as it approaches the Willow Beach entrance station.

The result is to have two signs staggered each side of the access road for visitors and LAKE staff approaching the entrance station see and take notice of adverse conditions that may be imminent. The sign will be connected to the current flash flood sign system that send status messages to the Lake Mead Information Communication Center (LMICC) for events of flashing flooding in the Willow Beach area. Attachment B contains the project location map.

3.2. Maintenance of the flash flood warning systems at both Willow Beach and Cottonwood Cove be established on an annual basis for hardware and software diagnostics and upgrades as warranted. The current conditions of signs at each site consist of outdated circuit boards and legacy alert software. Annual maintenance support would allow for site visits to visually inspect the signs, replace hardware, run diagnostics to ensure the system is functional for reporting adverse occurrences.

3.3. The Contractor will be responsible for installing sign frames upon the approach to the entrance station. The frame, sign panels, and warning lights will be provided by the contractor and will be in like kind in dimension to the current signage currently in place.

3.4. The Contractor will provide the necessary connectivity and power of the entrance station sign to be synced with the existing flash flood signs where in the event of a flash flood through the activation triggering of rainfall rate, water level, and/or LMICC (Dispatch) enabling. This will trigger the flashing warning light on the sign and signal the dispatch staff at the LMICC of the event for proper notification to personnel.

The Contractor shall physically verify the location and elevation of the existing utilities prior to sign installation. The Contractor shall contact Dig Alert (811) for Arizona / Nevada, and the LAKE Facility Management for assistance in locating existing utilities. If required to confirm the existence or absence of utilities in undocumented locations, the Contractor shall scan the construction site with electromagnetic and sonic equipment and mark the surface of the ground where existing underground utilities are discovered.

5.1.1. Workmanship and neat appearance shall be as important as the electrical and mechanical efficiency of the system.
