- 9 -

H. As directed by a Certified Arborist, additional tree protection mitigation techniques to reduce construction impacts to trees may require:

1) worker education about tree protection

2) supplemental watering

3) mechanical aeration coring to break-up compaction and improve water/oxygen percolation within the drip-line root zone area surface

4) root pruning and root invigoration

5) branch and limb pruning

6) dust control and leaf rinsing to reduce dust build-up on leaf surfaces

7) avoiding leaf scorch and other tree tissue burning by directing equipment exhaust pipes and/or engine heat away from tree surfaces

8) layer mulching of the surface within the drip-line root zone area in order to insulate the soil surface from sun exposure and to retain soil moisture

9) tree trunk protection devices such as board wrapping and/or fabric cushioning

10) root zone soil compaction protection such as steel plating over a layered mulch cushion

11) other measures as directed by a Certified Arborist

I. Tree protection zones must be delineated with temporary fence as indicated on the Plans or as directed by a Certified Arborist. Refer to these Special Provisions Section 10-13.02 regarding Type ESA temporary fence.

J. Supplemental watering of existing trees must be applied as needed throughout the project construction period in order to maintain tree health, vigor and structural integrity.

Supplemental watering may be accomplished with soaker hoses, “tree-gators”; temporary irrigation systems, flood bubblers, contained flood irrigation, and/or cycled truck watering.

K. Trees that have died or that are exhibiting irreversible stress damages due to unauthorized construction impacts and/or lack of adequate tree protection measures must be replaced by the Contractor at Contractor’s cost, including payment of any environmental mitigation fees and/or tree value loss to the tree owner. Tree loss or damages due to tree-owner inflicted causes are not the responsibility of the Contractor.

L. During the final walk-through of the project, the pre-construction tree inventory will be compared to the final condition of the trees to determine the adequacy of project tree protection and to determine any additional application of tree protection measures, including tree replacement and/or environmental mitigation fee and/or tree value loss payment if required.

The contract ALLOWANCE for Protection of Existing Trees shall include full compensation for furnishing all labor, materials, tools, equipment, and incidentals, and for doing all the work involved in protecting existing trees, as specified in these Special Provisions and as directed by the Engineer. The total amount to be paid for the work included in the ALLOWANCE for Protection of Existing Trees shall be the amount of the allowance actually utilized in the course of completing the work and no additional compensation will be allowed therefor.

Trees to remain must be protected and any root or limb cutting of trees to remain must be per the direction of the certified arborist.

A certified arborist must evaluate the impact of root or limb cutting on each tree as necessary and make recommendations regarding safety and retention. If the arborist deems that the root or limb cutting is too severe and will cause the tree to die or become unsafe, he/she must make such recommendations in writing to the County Inspector.

The payment for all labor and material associated with arborist services for the protection of existing trees shall be included with the line item for Protection of Existing Trees, and no additional compensation will be allowed therefor.
