Facilities; and other existing construction.

d. “Selective removal” means removal of specific trees, shrubs, brush, and other vegetation, whether as shown or indicated in the Contract Documents or as directed at the Site by COR.

e. “Selective trimming” means removal of selected parts of trees, shrubs, brush, and other vegetation, performed by arborist, for the purpose of either: (1) allowing installation of new construction adjacent to or through the tree, shrub, brush, or vegetation, or )2) removing damaged or unhealthy growth, to allow balance of the subject tree, shrub, brush, or vegetation to continue normal, healthy growth.

Trimming”.

C. Trees and Shrubs to Remain:

WICA - 245889 & 246063 31 10 00 - 5

1. Trees and shrubs to remain shall be protected, and trimmed where necessary or required, in accordance with this Section’s Article, “Tree Protection, Selective Removals, and

3.4 TREE PROTECTION, SELECTIVE REMOVALS, AND SELECTIVE TRIMMING

A. General Provisions for Tree Protection, Selective Removals, and Selective Trimming:

1. Provide temporary fencing, barricades, or guarding measures, as recommended by arborist, outside drip line of trees and shrubs to remain.

2. Protect root systems from damage caused by noxious materials, storm water runoff, site clearing, planting and landscaping, other Work, and storage of materials and equipment.

Protect root systems from flooding, erosion, and excessive wetting resulting from dewatering of excavations, drainage of tanks, and other construction activities.

3. Fires are not allowed under or adjacent to trees, shrubs, and other vegetation to remain.

4. Do not store matter resulting from site clearing or demolition, topsoil, or other excavated material within drip line of trees and shrubs to remain. Vehicles are not allowed within drip line. Restrict foot, vehicle and equipment traffic to prevent compaction of soil over root systems. Where such activities are unavoidable, and only as acceptable to COR, provide temporary, continuous, heavy-duty wood planking effectively fastened together and capable of distributing loads from such activities. Temporary planking shall be underlaid by layer of filter fabric covered with two-inch layer of gravel.

5. Cut branches and roots, when necessary, with sharp pruning instruments; do not break or chop. Fully paint cuts 1/2-inch and larger in size with tree wound dressing.

B. Excavation and Protection of Trees and Shrubs:

1. Excavate within drip line of trees only where shown.

2. Where trenching for utilities is required within drip line, tunnel under or around main lateral feeder roots by drilling, auger boring, pipe jacking, or digging by hand under supervision of arborist. Do not cut main lateral roots or tap roots; cut smaller roots, which interfere with installation of the Work.

3. Where excavation for the Work is required within drip line of trees or shrubs, hand excavate to minimize damage to root systems. Perform excavation under supervision of arborist. Provide temporary shoring or other protective support systems at excavations, to minimize sloping and benching of excavations. Use narrow tine spading forks and comb excavated material to expose roots.

4. Relocate roots in backfill areas wherever possible. If large, main lateral roots are encountered, expose beyond excavation limits as required to bend and relocate without breaking. If encountered immediately adjacent to location of construction and relocation is not practical, cut roots approximately three inches back from construction.

5. Do not allow exposed roots to dry out before permanent backfill is provided; provide temporary earth cover. Water and maintain in moist condition and temporarily support and protect from damage until permanently relocated and covered with earth.

C. Grade Adjustments and Tree Protection:

1. Maintain existing grade within drip line of trees, unless otherwise shown or indicated.

2. Lowering of Preconstruction Grade:

WICA - 245889 & 246063 31 10 00 - 6

a. Where required finish grade is below preconstruction grade around trees and shrubs, grade beyond drip line. Maintain preconstruction grade within drip line of trees and shrubs.

b. Prune tree and shrub roots exposed during grade lowering, or provide permanent protections as recommended by arborist. Do not cut main or lateral roots or tap-roots; cut only smaller roots.

c. Compensate for loss of roots and prune branches to stimulate root growth.

d. Provide extended service through completion of the Contract correction period as recommended by arborist.

3. Minor Fills:

a. Where preconstruction grade is six inches or less below elevation of finish grade shown, fill with topsoil complying with quality requirements of Specifications for finish grading and landscaping.

b. Place in single layer and do not compact.

c. Hand-grade to required finish elevations.

D. Tree and Shrub Pruning (Selective Trimming):

1. Perform pruning and selective trimming under the supervision of arborist.

2. Remove branches from trees and shrubs to remain only after COR’s concurrence, only to extent necessary to clear location of permanent construction, using branch removal methods in accordance with ANSI A300 and applicable ISA standards indicated in this

Section’s “References” Article.

3. Extend pruning operation to restore natural shape of entire tree or shrub where pruning is approved by COR.

4. Prune branches to balance loss to root system caused by damage or cutting of root system.

5. Chip branches removed from trees and shrubs. Stockpile and spread chips as directed by

COR.

E. Selective Trimming:

1. In addition to pruning (as required above), perform other selective trimming under direction of arborist.

2. Comply with ANSI A300 and applicable ISA standards indicated in this Section’s

“References” Article.

3. Where shown or indicated, and as directed by COR with arborist’s recommendation, carefully remove larger branches, when necessary, using appropriate methods.

4. Repair cut branches in accordance with this Section.

5. During selective trimming, avoid damaging healthy (to remain) elements of trees and shrubs.

6. Dispose of trimmings as indicated in this Section’s “Disposal and Cleaning” Article.

F. Selective Removals:

1. Perform selective removals under direction of arborist.
