Senate committee hears calls to study water district policies and protect mature trees amid turf-removal programs

Senators on the Senate Committee on Legislative Operations and Elections heard public testimony and expert evidence on SB 143, a bill that would direct legislative review of water-conservation policies and oversight for water agencies serving the Las Vegas Valley.

Senator Rochelle Winn, who represents part of Clark County, opened the hearing by saying older neighborhoods with mature trees are being harmed by recent conservation incentives and penalties and that the bill was intended to bring ‘‘science to the table’’ and add community voice to policy decisions. Laura McSwain of the Water Fairness Coalition and resident witnesses described steep fees and mandatory turf conversions that they say are damaging long-established urban landscaping.

Why it matters: Witnesses told the committee that removal of turf around mature trees, and conversion to artificial surfaces, can worsen the urban-heat island effect, harm tree health and impose substantial, unplanned costs on homeowners and homeowners associations (HOAs). Arborists and a university turf specialist presented research showing trees plus turf provide larger cooling benefits than turf or trees alone and cited other states’ experience — particularly California — that exempted turf under trees after voluntary removal programs caused tree mortality.

Testimony and evidence

Laura McSwain, founder and president of the Water Fairness Coalition, said residents have experienced “excessive use charge penalties” and described the Southern Nevada Water Authority (SNWA) as pursuing what she called “Project Armageddon,” a phrase she said she learned was used internally. McSwain said records requests and appeals to agency boards had produced limited accountability and that SB 143 would be a first step toward restoring oversight.

Stacy Stanley, president of the Spanish Trail Homeowners Association, provided a community-level accounting: he said Spanish Trail had already removed roughly 550,000 square feet of turf before AB 356 and that SNWA guidance would require removing a total approaching 1,000,000 square feet—placing about 6,000 mature trees at risk. Stanley told the committee he and local landscapers used numbers from NTRAC advisory materials to estimate average conversion costs at $7.50 per square foot and in some waiver cases up to $13 per square foot before rebates, producing multi‑million dollar bills for large common‑area conversions.

Kelly Cope, a landscape water‑conservation and turfgrass specialist at Utah State University, testified about the environmental services turf and trees provide. Cope said turf and trees together amplify cooling through shade and evapotranspiration, and she cited a Desert Research Institute study of Wells Park in Henderson showing turf removal raised surface temperatures substantially. Cope also presented examples in which replacing high‑use turf with low‑water varieties, improved irrigation and smart controllers reduced water use by 30–55% without wholesale turf removal.

Local professionals and residents

Arborist Norm Schilling and other local tree specialists testified in support of the bill, telling the committee they are seeing widespread decline of mature trees after turf and irrigation changes. Several homeowners and HOA representatives described denied waiver applications, surprise bills and exhausted reserves to comply with mandatory conversions.

Agency response and neutral testimony

A representative of SNWA (Rob Belanger) said the agency would provide information to an interim legislative review and urged the committee to examine the rationale for existing conservation measures; Belanger described the bill’s study provisions as an opportunity to explain the authority’s actions and the reasons behind them.

What the bill would do

SB 143, as presented, would direct evaluation of water‑conservation measures and agency practices and provide the Legislature with findings and any recommendations for change. Witnesses urged the committee to consider targeted exemptions (for turf under trees) or alternative conservation strategies (irrigation audits, low‑water turf varieties and smart controllers) that can deliver water savings without the tree loss they described.

Closing and next steps

Senator Winn closed by thanking the many residents and experts who testified; the committee did not vote on SB 143 at the hearing. Supporters asked the Legislature to act quickly, citing continuing tree loss they attributed to current policy implementation.

Votes at the hearing: none recorded on SB 143; the committee instead took public testimony and heard neutral presentations from the SNWA.
