- PRUNING

• Minimize ground disturbance.

• All cuts shall be made using International Society of Arboriculture (ISA) best management practices.

• Natural tree forms shall be preserved to the extent possible.

• Trees shall not be “topped” without prior approval by the Contracting

Officer’s Representative (COR).

• Remove dead or diseased material.

• Remove all hazardous limbs or main stems of trees, using acceptable arboricultural practices, if these parts of the tree would create a hazardous condition.

• Remove such limbs as may be necessary for the maintenance of tree symmetry when, as in heavy pruning on one side, a condition of imbalance is caused to exist.

- TREE REMOVAL

• See note about work performance period regarding protecting bat and bird habitat.

• Trees that cannot be felled due to proximity of buildings, powerlines, monuments, or other historic features shall be topped and/or sectioned.

Whenever possible trees should be felled on level ground as possible, avoiding stumps, rocks, etc. that may cause the tree to roll when it falls.

• Pull ropes shall be used on all trees that have the potential for damage to monuments, buildings, historic fences and/or other historic features. Pull ropes shall be installed before any cutting is done at the base. Stake holdfasts and individuals pulling ropes shall be outside the striking distance of the tree. If the conditions make this impossible, the tree shall be topped and/or sectioned.

• A mechanical mulcher can be used to masticate all dead, hazardous, damaged tree sections and vines.

• All trees shall be flush cut at ground level.

• Site shall be restored to the same or better condition than it was in before work started.

• Work areas shall be raked clean and restored to the same condition as was present prior to the commencement of work.

IV. PROJECT PERFORMANCE PERIOD

All work shall be completed within one hundred and twenty (120) days of award.

Activities including mulching and/or removing collapsed trees and logs may take place at any time after award and in consultation with the Contracting Officer’s Representative.

Any tree deemed to be used by bat species for diurnal and maternity roosting will be left in place. Peak bird use of individual trees for nesting also occurs during the spring and summer. If necessary to remove trees with bat or bird species due to hazardous nature of the tree and tree location, the period of performance will be extended if necessary to accommodate vacancy of bat and bird species.

V. BID FORMAT:

1. Prior to the bid deadline, the Park will host a pre-bid meeting to show bidders the project areas and locations of trees, storm-damaged branches, vines, and piles of branches listed in Attachment 2.
