Trees of Osage Orange shall be cut off as specified for all other tree species, pulling or grubbing of Osage Orange trees shall not be allowed. (Modifies 201.04 of the Standard Specifications)

POST-REMOVAL TREATMENT

Within the growing season following brush removal, apply Foliar Mixture 1 to the leaves of target species re-sprouts and/or seedlings after leaves have fully opened in the spring. Provide full coverage of the leaves while limiting overspray and dripping. If the Contractor determines that follow-up treatments risk injury to adjacent non-target trees, re-sprouts/seedlings shall be cut utilizing hand-operated equipment and stumps treated according to Removal Method 2.

The Contractor shall conduct woody species herbicide treatments to all cut-stumps, re-sprouts, re-growth, or other remaining live plants of all target species.

DISPOSAL

All cuttings longer than two (2) feet in length and/or larger than one (1) inch in diameter shall be removed from the project site. Smaller cuttings and cutting debris that has been shredded or chipped using hand-held mechanical equipment may be left on site to decompose. Cuttings and cutting debris shall neither be allowed to accumulate to a depth that will smother existing desirable vegetation and prevent it from emerging, nor prevent good seed-to-soil contact in newly seeded areas (approximately one (1) inch maximum depth). Any areas as determined by the Engineer to have mulch or debris at a depth that may impact vegetative growth, the Contractor shall rake and remove excess mulch debris at no additional cost.

Dispose of cuttings, logs, mulch, stumps, root material, sod, rubbish, surface debris, or other material off State property. Contractor shall provide documentation to the Engineer of disposal methods prior to final inspection. Disposal of cuttings and other materials shall be completed simultaneously with the initial tree removal operations. Disposal options for this work include:

For any mulch or other debris requiring removal from mechanized equipment usage, the Contractor shall haul the material off site for appropriate disposal. For any whole trees removed from hand-operated equipment usage, the Contractor can either chip removed trees on-site and haul the chips away or haul whole cut trees and branches off site for appropriate disposal. This requires the Contractor to dispose of cut tree material at an off-site facility of their choosing.

methods shall be proposed by the Contractor at the pre-construction meeting. If alternative disposal methods are not approved, the Contractor shall dispose of materials as specified.

The collection and stockpiling of cuttings, logs, stumps, root material, sod, rubbish, surface debris, or other materials throughout construction shall not result in pitting, rutting or any other soil disturbances. Mechanized collection, transport, and stockpiling shall be permitted only under these conditions.

Stockpiling areas shall be as shown on plans or shall be determined by the Engineer using the following criteria:

• Does not impede traffic

• Does not cause a hazard to the motoring public

• Is no closer than fifteen (15) feet to any roadway with curb and/or functional guardrail

• Is no closer than thirty (30) feet to any roadway without curb and/or functional guardrail

• Ease of access

• Site lines (placement of piles shall not disrupt views from adjacent roads)

Stockpiling shall not be allowed in wetland areas

All disposal costs shall be considered incidental and no additional compensation will be allowed.

SITE RESTORATION

The Contractor shall fill and smooth any ruts or other ground disturbance created by the tree removal operations, finished planting surface shall be free of clods, rocks, and other debris measuring two inches (2”) or more in any dimension or as otherwise directed by the Engineer.

Disturbed areas shall be seeded and mulched within 48 hours of the disturbance, unless otherwise directed by the Engineer.

Restrictions:

Storage of materials shall be prohibited within environmentally sensitive areas as determined by the Engineer.

Without proper traffic control in place, staging of cut material shall not occur within fifteen feet (15’) of any roadway with curb and/or functional guardrail nor within thirty feet (30’) of any roadway without curb and/or functional guardrail.

Unless otherwise directed by the Engineer, cut material shall be disposed of the same day it is cut and work areas shall be cleaned at the end of each day. Stockpiles shall not be allowed to remain on-site overnight.

Method of Measurement:

This work will be measured for payment in Acres as per Section 201.10 (b) (2) of the Standard Specifications.

The area containing trees to be removed will be determined in the field by the Engineer, and the quantities will be adjusted accordingly.

10% of this pay item will be held as retainage until final completion of the entire project. The Engineer will release retainage upon issuance of final completion.

Basis of Payment:
