A. Scope: Contractor to remove and dispose of individual trees, as marked by the Forest Service.

Individual trees shall be marked with pink flagging. All debris, marked trees, stumps, roots and other protruding vegetative material shall be cleared, grubbed, removed or disposed of in accordance to the specifications.

B. Vegetation Removed: Do not bury, landfill, or leave on site, except as indicated.

1. There are 52 hazard trees to be cut. No tree will be more than 24” in diameter. Any additional trees, including those added or those over 24” in diameter, will be negotiated on a per tree basis after the task order has been awarded.

2. All trees, with a 3” diameter or greater and up to a 3” top, must be limbed and bucked to a length between 18” and 24”. Cut pieces must be stacked adjacent to campsites or roadways, in a location approved by the COR.

3. Slash (tops, limbs and trees under 3” diameter) must be chipped by the Contractor to be used for mulching on site. Chips on Government property must be spread. The average depth of the chips cannot exceed 3 inches above ground surface.

4. Contractor must grind or remove all stumps which are created by the Contractor in the act of cutting a hazard tree within five feet of a use area (campsite, picnic site).

It is estimated that 20 stumps will need to be ground or removed. Other stumps may remain.
