Clark County is responsible for land use planning in all areas outside of the incorporated cities. For land use planning purposes, the unincorporated portion of Clark County is divided into 11 planning areas. Seven planning areas are in the Las Vegas Valley—Enterprise, Lone Mountain, Spring Valley, Summerlin South, Sunrise Manor, Whitney, and Winchester/Paradise. Four others represent the outlying areas of the County-Laughlin, Northeast County, Northwest County, and South County— and all the communities within those areas. The County maintains separate goals, policies and planned land use maps for each planning area, as contained in this section.
