Enterprise is a large unincorporated CDP in the southwest Las Vegas Valley where summer temperatures regularly exceed 115°F, causing thermal expansion damage to supply lines, roofing membranes, and PVC irrigation systems. The area is crossed by several natural desert washes that Clark County has partially channelized, but intense monsoon thunderstorms can overwhelm capacity and send flash floods through residential areas with little warning. The valley's caliche-hardpan soil sheds water rapidly, concentrating runoff into these wash systems.
High-risk neighborhoods
Mountain's Edge and Rhodes Ranch homes built near natural desert wash corridors face the highest flash flood risk during monsoon season when Clark County channels can be overwhelmed within minutes; newer subdivisions on compacted clay soils in the southern Enterprise area experience foundation seepage and crawl space moisture during unusually wet winters.
