The Southern Nevada Water Authority has asked a Clark County District Court judge to dismiss a lawsuit alleging that grass removal led to thousands of valley trees dying. You may remember that several local residents sued the agency and argued the SNWA’s grass removal mandates lack proper legal and constitutional oversight. The lawsuit argues that only 10% of trees in the Las Vegas Valley survive after grass removal and that the policies have created a “valley-wide graveyard of trees” that would take decades to recover. According to court records filed last week, the SNWA states the plaintiffs in the case were already paid to have grass removed, so they “cannot complain about prospective nonfunctional grass designations.”
