LAS VEGAS (FOX5) — Conservation groups are pushing back against a new state mapping tool that identifies federal lands potentially available for development in Nevada.

The governor’s office, in partnership with the Bureau of Land Management Nevada, unveiled the interactive map this week to make it easier to find federal land that may be available for development throughout the state and in the Las Vegas Valley.

“It is shocking to look at the map and see how many lands could potentially be sold off,” said Olivia Tanager, executive director of the Sierra Club Toiyabe Chapter.

Tanager said she was surprised at how many federal lands were identified for disposal when she first looked at the map.

“Places like Red Rock and Sloan Canyon in Southern Nevada are what draw people to live in Southern Nevada. We cannot continue to develop right up onto the boundaries or perhaps even in these precious places,” Tanager said.

The conservation group says the mapping tool is the latest effort to treat Nevada’s public lands as a real estate inventory rather than a shared public resource.

“We know that a lot of these areas are environmentally sensitive. We know that there are endangered species on these lands,” Tanager said.

Housing concerns

Lawmakers have proposed using federal lands to create more affordable housing. Several areas at the edges of the Vegas Valley have been identified for potential development on the mapping tool. Tanager said she does not see that as a viable solution.

“The areas on the outskirts or far outside of existing urban areas are wholly inappropriate for affordable housing. Housing that is located that far away from services will never be truly affordable,” Tanager said. “As folks have to live further and further away from resources like schools and grocery stores, transportation costs go up substantially.”

The conservation group says the valley should fill in open lots and build upward within the existing urban core instead of building outward.

“We know that sprawl and developing on the outskirts of the valley worsens air quality as well from increased transportation,” Tanager said. “We know that sprawl is incredibly water-intensive. The further out you build, the harder it is to recapture that water.”

The Sierra Club Toiyabe Chapter says treating federal lands as disposable assets could set a dangerous precedent that accelerates privatization efforts and undermines the principle that public lands should remain in public hands for future generations.

Approximately 85% of Nevada’s total land area is owned by the federal government.

The state says the tool is designed to bolster information sharing about federal lands. The mapping tool is available here.

LAS VEGAS (KSNV) — In the desert climate of Southern Nevada, WOW Carwash says it is working year-round to conserve water and reduce its environmental impact, using a combination of water-reclamation technology, biodegradable soaps and energy-efficient equipment.

The Las Vegas-born company says washing a car at home uses roughly 100 gallons of water. By comparison, WOW says it uses about 30 gallons per vehicle and reclaims up to 80% of the water.

WOW says its water-reclamation system exceeds typical local requirements. While local car washes are only required to have one sand and oil separator, WOW says it has four, along with a mud tank and UV filters designed to recycle water, reduce daily water use and ensure no solids are sent to the sewer system.

The company says all water from a WOW Carwash enters a 1,500-gallon mud tank underground at each location to begin separating soils from the water. From there, WOW says the water passes through a series of four sand and oil separators, where oils float to the surface, and soils sink to the bottom. WOW says the cleaned water is then pumped through UV and micron filters to remove remaining contaminants so it can be recycled and reused in the car wash.

WOW also says it repurposes the dirt washed off vehicles. The company says its water-reclamation tanks are pumped regularly by licensed vacuum trucks to maintain efficiency, and what is pumped out is then utilized as fertilizer.

WOW says all cleaning agents used in its tunnel wash process are environmentally safe and biodegradable, and that the soaps are safe to the human touch and for a vehicle’s paint while still being tough on dirt. The company says the cleaning agents break down naturally, reducing harmful runoff that could otherwise flow into storm drains and local waterways.

To reduce its carbon footprint, WOW says it uses energy-efficient equipment, including Variable Frequency Drives that allow electric motors to “ramp down” when demand is low to reduce electricity use during operations.
