SUMMARY OF WORK

1.1 WORK COVERED BY CONTRACT DOCUMENTS

Project Location: This project is in the Boulder Beach area of Lake Mead National Recreation Area (LAKE). 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.

Scope Summary: Work under this contract consists of providing all labor, supervision, equipment, rigging, aerial lifts, cranes, traffic control, debris hauling, and disposal necessary to perform hazardous tree mitigation and canopy maintenance within the Boulder Beach developed area of Lake Mead National Recreation Area. 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. Work shall be performed in developed recreation areas that remain open to visitors during operations. The contractor shall coordinate work sequencing to maintain safe public access and minimize disruption to campground operations, park housing, and harbor facilities.

A. General: The park is committed protecting natural and cultural resources found within the park and adjacent lands. The Contractor must comply with the following rules and conditions:

1. Invasive Species: The introduction of non-native invasive species can threaten rare and endangered species or can create new populations of non-native species not traditionally found in the park. The contractor is required to inform personnel, subcontractors, and vendors to thoroughly clean all vehicles, equipment, tools, supplies, and materials prior to packing / loading. The park requires, and will perform, inspections to ensure non-transport of non-native species PRIOR to arriving at the park entrance. Contact the Contracting Officer’s Representative (COR) at least five (5) business days in advance of park entry to arrange for inspection(s) at the loading dock or point of origin.

2. Endangered Species: Endangered species are protected by Federal law. Obey all park regulations. Drivers must obey all traffic laws and keep an eye out for animals on or alongside road. Contact Park dispatch at 702-293-8998 immediately if animal is hit or injured or will not move off the road. All vendor personnel working in Lake Mead National Recreation Area must have up-to-date Lake Mead Desert Tortoise Awareness Training. Prior to starting work, contact the Contracting Officer’s Representative (COR) at least five (5) business days in advance to schedule the desert tortoise awareness training.

The following endangered species are found within the park and require certain considerations.

a. Desert Tortoise – Training Required

b. Razorback Sucker – Additional requirements for aquatic activities

c. Humpback Chub - Additional requirements for aquatic activities

3. Archaeological Resources: Archaeological resources are physical evidence of past human activity, including evidence of the effects of that activity on the environment. Archaeological resources are found above and below ground and underwater. The contractor shall appoint an archaeological monitor during all ground-disturbing activities in archaeological sensitive areas. If the monitor discovers resources, the contractor shall stop work or relocate work to a non-sensitive area and contact the contracting officer immediately. Archaeological resources typically found in the park or at the project site will be discussed further at the pre-work meeting.

4. Nesting Birds: Bird Nesting season is between March 1 and August 31. All work performed in this time frame requires monitoring by park biologist. Working outside of this time frame does not require additional monitoring. If active bird nests are discovered, halt work on that tree and notify the COR immediately. All trees must be surveyed for bird nests prior to the beginning of work on each tree.

5. Soundscape / Noise: The contractor shall minimize noise levels at the project site to protect the soundscape of the park. Perform noise-producing work in less sensitive hours of the day or week or as directed by the contracting officer.
