The work is divided into several subareas as depicted on the site map (Appendix). The areas include BB Picnic Area, BB housing, VIP BB Campground, BB Campground, and Boulder Harbor. Boulder City is the nearest town, and Las Vegas is the nearest major metropolitan area. Project Background: The Boulder Beach Area at Lake Mead National Recreation Area is a heavily used developed recreation area encompassing approximately 70 acres and containing more than 500 mature trees, including cottonwood, palm, eucalyptus, desert willow, palo verde, mesquite and tamarisk species. Over time, many trees within the campground have experienced unmanaged growth, resulting in excessive canopy weight, dead limbs, basal suckers, and standing dead trees. These conditions create increasing safety concerns in areas frequently occupied by visitors and staff. Routine maintenance has not fully addressed the accumulation of hazardous tree conditions, and a comprehensive trimming and removal effort is necessary to restore safe operating conditions within the campground. This project represents a planned corrective maintenance action to address identified hazards and maintain the safe use and functionality of this developed visitor facility.

The work includes pruning, deadwood removal, canopy thinning, palm trimming, removal of standing dead trees, stump grinding, debris hauling, site protection, and restoration of disturbed areas.
