2.0. WORK LOCATION AND PERIOD OF PERFORMANCE.

2.1 Work Location: Moapa Valley National Wildlife Refuge (MVNWR), 4225 West Warm

Springs Road, Moapa, Nevada 89025.

New Gage Coordinates: 36.71050112, -114.71467166

The new stream channel will be immediately downstream from the coordinate values noted above. The USFWS does not know the exact coordinates for the new stream channel because this will depend on the design/engineering performed.

2.2 Period of Performance:

Start Date: October 1, 2020 – Estimated (Depends on NTP Date).

End Date: September 30, 2021 – Estimated (Depends on NTP Date).

Site Conditions of the area of interest consists of a thermal spring system, riparian areas, and desert uplands. The soil in the area is sandy loam. Although dace can spawn year-round, peak spawning occurs during spring and early summer. Therefore, work within the stream itself will be restricted to fall and late summer.

In-Water Construction Work Window:

(October 1 – March 1 and July 1 – September 30).

In the event of damage to government property resulting from construction, the contractor shall return the damaged area to its original condition. The contractor will also be instructed where to access the Construction Site to minimize potential damage to the existing resources.

The Period of Performance for this Contract is 1-year from the actual date of Notice to Proceed (NTP) Letter. Anticipated Delivery Date for NTP Letter is 30 Days Following Initial Contract Award Date. Above dates shown are tentative and subject to change.

Contractor shall coordinate with the Refuge Manager and/or Project Leader for a Proposed Construction Work Window. The Final Accepted Construction Work Window will be mutually agreed to between the Contractor and USFWS Moapa Valley NWR prior to Construction.

2.3 Normal Business Hours for the Refuge, Monday thru Friday 7:00 a.m. - 5:00 p.m. Work Activities shall be performed during Normal Business Hours. Limited accommodation to an alternate schedule may possible with coordination with on-site FWS staff. In the event of emergencies, Contractor shall provide contact information.

2.4 Non-duty hours include week nights, weekends, and Government holidays (New Year’s Day, Martin Luther King JR.’s Birthday, President’s Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veteran’s Day, Thanksgiving Day, Christmas Day).

3.0. DEFINITIONS.

Not Used.

4.0. BACKGROUND.

The Moapa Valley National Wildlife Refuge (MVNWR) is operated by the U.S. Fish and Wildlife Service (USFWS). It is located approximately 10.3 miles northwest of Glendale, Nevada. The nearest major City/town is Las Vegas, Nevada located approximately 58.7 miles southwest of MVNWR.

The Future Awarded Contract is to result in the Design-Build of approximately 500 feet of

Naturalized Stream Channel in Pedersen Stream at Moapa Valley National Wildlife Refuge (MVNWR) in Clark County, Nevada. The Muddy River Ecosystem in Clark County, Nevada begins in the Warm Springs Area where thermal springs from the regional carbonate aquifer coalesce over a short distance to create the main stem Muddy River. Many endemic, thermophilic species occur in the Warm Springs Areas including the monotypic Moapa dace (Moapa coriacea), which was originally listed as an Endangered Species in 1967 and subsequently designated with a recovery priority of 1 (highest priority) in the Endangered Species Act of 1973. There are currently three barriers to fish passage (culvert, stream gauge, and waterfall) on the Pedersen Stream and a newly-constructed channel and culvert are required to allow Moapa dace to move freely upstream to the springhead.

Purpose.

The purpose of this project is to restore connectivity between breeding habitat located in the Pederson stream springhead on the Moapa Valley National Wildlife Refuge and downstream habitat on the privately-owned Warm Springs Natural Area (Southern Nevada Water Authority) for the federally-endangered Moapa Dace (Moapa coriacea). Restoring connectivity will enable dace to access breeding habitat through installation of a reinforced concrete box culvert, relocation of an existing US Geological Survey stream gauge, and excavation of new stream channel to re-route a portion of the stream.
