HAZARD TREE EVALUATION

GRAND CANYON NATIONAL PARK

STATEMENT OF WORK – Revision 0001 - 3/30/2022

1. GENERAL:

The National Park Service (NPS) and Grand Canyon National Park (GRCA) have a responsibility to manage hazardous trees (HZT) in the park’s developed areas to provide for visitor, resident, and employee safety. The HZT program is programmatic in nature, is implemented in accordance with the park-wide Hazard Tree Management Plan 2022-2026 and associated compliance documents and is guided by NPS Management Policies (2006) and NPS Natural Resource Management Guidelines (2001).

A hazardous tree is one that located in an identified public use area or facility, and because of a recognizable defect or mechanical flaw, poses a threat to people, property, or resources. Trees must meet two requirements: 1. show tree potential for failure and/or defect and 2. pose a threat to a target (people, property, or resources), before it is considered for removal through the park's HZT program.

The park’s developed areas include the South Rim, North Rim, and the Inner Canyon (Havasupai Garden, Phantom Ranch, Cottonwood Campground, and Roaring Springs). This statement of work (SOW) covers the complete evaluation of trees within the park’s developed areas, on an annual schedule to be determined. There is some flexibility in the timeline for work completion, but evaluations must be completed by the deadlines provided in Table 1.

This SOW does not cover the review or evaluation of emergency and/or urgent tree removal situations. The contractor will have a professional level of expertise (skilled pathologist or arborist) that is not available in the park. The contractor will not complete the hazard tree removals.

2. WORK TO BE PERFORMED BY CONTRACTOR:

1. Contractor shall evaluate potential hazard trees of any tree species and size in developed areas within the South Rim, North Rim, and Inner Canyon regions of GRCA using a data collection device and application provided by the park. The contractor will provide prioritized recommendations for mitigating the hazard ranging from tree monitoring, pruning, or full tree removal. The contractor will provide pricing for the 11 areas listed within the four primary developed zones. Table 2 represents the most common trees found within GRCA and serves as example only of what a contractor may encounter in the performance of the proposed contract.

Contractor and all contractor employees shall hike into the canyon for Inner Canyon projects located at Havasupai Gardens, Phantom Ranch, Roaring Springs, and Cottonwood Campground. Distances: South Rim to Havasupai Gardens is 5 miles one way with a change of 3000 feet via the Bright Angel Trail.
