Environmental features
Las Vegas is situated on the arid floor within Clark County. Correspondingly the environment is dominated by desert vegetation[citation needed] and wildlife[citation needed]; however, the setting is also subject to torrential flash floods which the infrastructure of storm sewers has not been able to contain.[citation needed] The rapid pace of urban development beginning in the 1980s has produced more impervious surface and exacerbated the inherent flooding issue.[citation needed] Enabling the rapid population expansion was a major addition to the city's sewage treatment capacity, an event removing a major constraint to population growth in the 1970s. The sewage treatment expansion resulted from a U.S. Environmental Protection Agency grant funded 208 program to analyse and forecast growth and environmental impacts through the year 2010.
