Statement of Work: Glen Canyon National Recreation Area Vegetation Management

Glen Canyon National Recreation Area (GLCA) has a requirement for a certified arborist to provide a professional assessment, trimming, and/or removal of trees and shrubs in front, side, and back yards at 51 employee housing units. These units exist in developed areas and share fences with adjoining properties that may or may not be private property. It is the intent of this project to trim vegetation, primarily trees, to a safe, neat and healthy state by removing overgrowth, hazards, and potential hazards to protect our government housing and neighboring properties from damage.

The work of this requirement includes:

1. An assessment and evaluation of the trees/shrubs at the 51 employee housing units listed in this statement of work.

2. A detailed plan of work for addressing the trees/shrubs at the 51 employee housing units listed in this statement of work. This plan will be subject to review and acceptance by

GLCA.

3. Trimming, removal and clean-up of hazard trees after receipt and acceptance of the plan (see item 2)

4. Option line item: Trimming, removal and clean-up of non-hazard trees and bushes after receipt and acceptance of the plan (see item 2)

The assessment and plan of work must be prepared by a certified arborist. All trimming, removal, and clean-up must be performed by or under the direction of a certified arborist.

Arborist(s) performing work within GLCA must be currently certified and qualified by the International Society of Arboriculture.

Work Areas:

There are four park housing areas, 51 housing units, that require attention: 11 in Page, Arizona;

10 in Wahweap Marina, Arizona; 25 in Bullfrog, Utah; and 5 in Halls Crossing, Utah (see tables 1-4). Park properties have young to mature trees from approximately 8 to 20 feet high and various sized shrubs/hedges. Existing conditions are generally as follows:

PAGE, ARIZONA

Page housing units are located within congested neighborhoods, each with cohabitating fencing and some with encroaching tree limbs from private citizen neighbor yards. Both car and foot traffic are moderate to heavy in these areas (see figures 1 and 2).

WAHWEAP MARINA, ARIZONA

Wahweap Marina housing units are located within park borders with no private citizen surrounding homes. Majority of the grounds are unfenced and rock landscaping. Four of the housing units are fenced, close together, and heavily treed (see figures 3 and 4).

BULLFROG, UTAH

Bullfrog housing units are located within park borders with no private citizen surrounding homes. Not all units are owned by the park, some are owned by other government agencies. Terrain is generally rock and sand with some lawns and a variety of tree types and sizes. Most units have at least one side fenced. This area is condensed but not much traffic (see figures 5 and 6).

HALLS CROSSING, UTAH

Halls Crossing housing units are located within park borders with no private citizen surrounding homes. Not all units are owned by the park, some are owned by other government agencies. Terrain is generally rock and sand and a variety of tree types and sizes. The four individual housing units are close together, sharing a fence. The quad unit does not have fencing but has associated trees lining the front and several yards from the back and side. This area has many large trees that are dead and need to be removed (see figures 7 and 8).
