About this program

The Department of the Interior Bureau of Reclamation funds management and restoration projects on the Las Vegas Wash tributary system under CFDA 15.540, with the most recent award issued on August 29, 2024, and no current open solicitation.

The program funds concrete environmental and water-quality activities along the Las Vegas Wash, which conveys approximately 200 million gallons daily of urban runoff, groundwater, and treated wastewater from the Las Vegas Valley to Lake Mead. Funded work includes erosion control structure design and construction management, riparian habitat revegetation implementation and monitoring, water quality monitoring in the mainstem and tributaries, invasive species and noxious weed removal, threatened and endangered species monitoring, archaeological investigations of cultural resource sites, and Las Vegas Wash Coordination Committee program management. Projects address specific action items from the Las Vegas Wash Comprehensive Adaptive Management Plan, which identifies 44 priority management objectives related to salinity reduction, sediment transport, habitat integrity, and recreation access.

Awards are predominantly Project Grants (88 percent, 14 awards) with a smaller share of Cooperative Agreements (13 percent, 2 awards). The Department of the Interior Bureau of Reclamation is the sole funding agency across the portfolio. Combined federal dollars obligated total $6.5 million, with $1.5 million in non-federal cost-share, across 16 awards since 2008. Recent awards cluster in 2015 (4 awards) and 2024 (2 awards), with sporadic activity in intervening years. The two most recent awards exemplify the scope: Project Grant R24AP00390 ($3.5 million, August 2024) for construction management and environmental monitoring through December 2030; and Project Grant R24AP00290 ($3.1 million, June 2024) for revegetation, water quality monitoring, wildlife adaptive management, invasive species removal, and habitat improvements through April 2029. A 2022 award ($3.6 million) funded geotechnical surveys, environmental permitting, and weir design for an erosion control structure at Lake Mead National Recreation Area.

The Southern Nevada Water Authority (SNWA) serves as the designated lead agency receiving all funding on behalf of the 28-member Las Vegas Wash Coordination Committee. The most recent posted opportunities date to 2019 and earlier; all were notices of intent to award with narrow due dates and no open competitive solicitation. Award decisions occur within 90 days or less after application receipt, subject to appropriations passage, with typical project terms extending five to six years.

Description

The objective of this program is to develop and implement management strategies for the Las Vegas Wash to improve water quality, habitat integrity, and reduce the salinity and sediment transport while providing environmental enhancement and recreational opportunities. The Las Vegas Wash Coordination Committee has decided that the SNWA will be the lead agency for receiving funding for this program due to the high costs and types of environmental improvement and enhancement, and ability to maintain restoration projects. The Las Vegas Wash Program plays an important role in environmental and water resource issues in Southern Nevada. Historically, the Las Vegas was an ephemeral stream carrying storm flows from the Las Vegas Valley to Lake Mead and the Colorado River. Urban development over the past 60 years has resulted in the formation of the wetlands that helped remove nutrients from these wastewater flows. As the rate of discharges increased, erosion also increased, gradually destroying the existing natural treatment systems and wildlife habitat and creating a large delta in the Las Vegas Bay of Lake Mead. Accelerating erosion, declining water quality, and loss habitat are some of the more pressing issues. Proposals submitted will be reviewed and awarded based on priority fulfillment of the 44 action items identified in the Plan and the availability of funding appropriations.

Award procedure

For grant agreements awarded as a component of the eligible beneficiary (SNWA) and project, approved by the Secretary of the Interior, and funded under Public Law 106-541 and subsequent amendments, all Federal rules, regulations, and agency specific guidelines for awarded procedures will be followed.

Time to approval or disapproval

The SNWA must submit written requests for renewals or extensions director to the Program Manager for approval, at least 45 days prior to the expiration of the specific project agreement. Once the term of the project is expired, no renewal or extension will be approved, due to non-compliance with the terms and conditions of the specific projects agreement.
