Spring Valley is an unincorporated community in western Clark County and one of the most populous census-designated places in Nevada, a dense suburb of Las Vegas. It shares the extreme desert heat and monsoon flash flood hazards of the Las Vegas Valley, where summer temperatures regularly exceed 115°F. Water supply dependency on a declining Lake Mead reservoir is a long-term systemic risk for all communities in southern Nevada.
