Opening page: Streetside, village, regional, and natural trails are the four components of the 160-mile (258-kilometer) trail system planned for Summerlin. It will eventually connect with Clark County's regional trail.

Above: Split into three distinct geographic areas, the 22,460-acre (9,089-hectare) site master plan is based on a hierarchy of planning elements: villages, neighborhoods, and village centers. It defines the nature and character of the 30 villages as well as the location of other major land uses and road alignments.

downs to calm traffic. Each neighborhood's street design, grading, landscape, and architecture go through a rigorous design review process guided by village-specific design guidelines.

Several of Summerlin's villages pursue niche and specialty markets, such as the two seniors-oriented villages of Del Webb's Sun City, which encompass 2,500 acres (1,012 hectares), three golf courses, and Sunrise Colony Company's Siena, a guard-gated community encompassing 665 acres (269 hectares).

An amenity village is the Ridges, a 795-acre (322-hectare) luxury golf course village featuring Jack Nicklaus's first Bear's Best Golf course, which incorporates replications of signature Nicklaus holes from the Southwest United States and Mexico. Red Rock Country Club, an upscale golf-course community situated on 738 acres (299 hectares), is being developed by Sunrise Colony Company and features two Arnold Palmer-designed golf courses, more than 1,000 luxury homes, and a 40,000-square-foot (3,716-square-meter) tennis, swimming, and health club.

## A Village Center

The system of villages is organized around three geographically distributed village centers, Summerlin Centre, the centrally located town center, and several business parks. Hills Village Center, the first village-level commercial center, is planned in a radial street pattern with the 38,500-square-foot (3,577-square-meter) Summerlin Library and Performing Arts Center at its center. The Plaza at Summerlin, a class-A multitenant office complex, the 36,000-square-foot (3,345-square-meter) Donald W. Reynolds Cultural Center, and the future gas station, health club, retail center, and business center are models for the other two future village centers.

The Crossing Business Center, Summerlin's first major business employment center, debuted in 1994 on a 115-acre (47-hectare) site in the Crossing Village. Central to the community along Town Center Drive, the Center draws its architecture from regional materials and colors, blending in with its Red Rock Canyon National Conservation Area backdrop.

## Ensuring Protection of the Land

Because Summerlin is located at an elevation higher than the rest of the Las Vegas Valley, careful consideration was given to building homes and facilities that maximize the glittering views of the Las Vegas Strip and the expansive valley to the east. Wherever possible, the natural topography has been preserved and incorporated into the landscape, including natural wash arroyos throughout the community's many linear parks and two Tournament Players Club golf courses. Much of Summerlin's trail system is built
