1)
Notwithstanding the provisions of this article, selective harvesting of timber shall be permitted where undertaken in compliance with a timber harvesting plan prepared by a qualified forester or equivalent professional and submitted to the Township prior to commencement of any timber harvesting operation per with subsection G. Except for approved timber harvesting, all woodland disturbances including regrading, removing, building upon, or otherwise altering shall be subject to the following total disturbance limitations, regardless of calculation of disturbance allowances for purposes of determining replacement planting requirements:
a)
Classes I and II, and woodland corridor or riparian corridor. Permitted woodland disturbance on any lot or tract shall not exceed 15 percent of any area designated Class I or Class II woodland, or any other woodland within a designated woodland corridor or riparian corridor on the Kennett Township Woodlands Classification Map and Woodland and Riparian Corridors map, except that, within C, LI, RMHD, V-H, and V-M Districts, such permitted disturbance may be increased to up to 40 percent.
b)
Class III and other woodlands. Outside of areas designated as woodland corridor or riparian corridor of § 240-1802.F.2.b.1)a), permitted woodland disturbance on any lot or tract shall not exceed 25 percent of any Class III woodland or any other unclassified woodlands or hedgerow(s) on the Kennett Township Woodlands Classification Map. This limitation shall not apply in C, LI, RMHD, V-H, and V-M Districts.
c)
Interior woodland. Permitted woodland disturbance on any lot or tract shall not exceed ten percent of any area designated as interior woodland on the Kennett Township Woodlands Classification Map.
d)
Disturbance limitations shall be measured based on the extent of the subject woodland classification at the time of first submission of applicable application(s) after the adoption of this section and shall be indicated on applicable plan(s) or permits. Any disturbance limitation shall run with the land, once established. Subsequent applications shall be subject to the initial determination of disturbance limitations, regardless of intervening disturbance which may have occurred. If at any time within three years prior to an applicable application there had existed a greater extent of woodland, such greater area shall be utilized to calculate the extent of woodland disturbance and the limitations set forth herein.
2)
Where disturbance to existing areas of woodlands and hedgerows exceeds standards set forth in the Subdivision and Land Development Ordinance, woodland replacement shall be required consistent with required vegetation replacement of said ordinance. Determination of the extent of woodland disturbance shall be as described in said ordinance.
3)
Guidelines for disturbance. When determining where permitted woodland disturbance will occur, the following factors shall be considered:
a)
The applicant shall consider the location(s) and benefit of conservation of healthy mature woodland stands and the classification of the woodland as shown on the Kennett Township Woodlands Classification Map.
b)
Each building or structure shall be constructed in such a manner as to provide the least alteration or disturbance necessary of the existing woodland. Clear-cutting shall be minimized, and trees shall be selectively removed.
c)
In each situation where the standards of this Section are applied, consideration shall be given to balancing the benefits of woodland preservation with other valuable resources on the site, including scenic views. The Township shall consider woodland disturbance where limited disturbance may permit siting of buildings in less visually obtrusive areas of the tract.
d)
The remaining undisturbed woodlands and other vegetation shall interconnect with woodlands or wooded areas of adjacent properties to preserve continuous woodland corridors and allow for the normal movement, dispersion, and migration of wildlife. The applicant shall consider the impacts, in terms of functions and values to wildlife, of separating, dividing or encroaching on wildlife travel corridors or extensive habitat areas, especially woodlands exceeding ten acres in area.
4)
Protection of woodlands to remain on-site. Woodlands, hedgerows, individual trees, specimen vegetation, heritage trees, and other vegetation that is to remain on the site shall be identified on the plan and protected from land disturbance and construction activities per the tree protection provisions of the Subdivision and Land Development Ordinance. In addition:
a)
Preserved woodlands and hedgerows may be used to provide the vegetative screens and buffers required by Article XX. Where necessary to meet the intent and minimum standards of such, additional planting may be required to supplement existing vegetation.
b)
Provisions for the long-term management of woodland areas not subject to woodland disturbance shall be consistent with the woodland management planning requirements of the Subdivision and Land Development Ordinance.

Notwithstanding the provisions of this article, selective harvesting of timber shall be permitted where undertaken in compliance with a timber harvesting plan prepared by a qualified forester or equivalent professional and submitted to the Township prior to commencement of any timber harvesting operation per with subsection G. Except for approved timber harvesting, all woodland disturbances including regrading, removing, building upon, or otherwise altering shall be subject to the following total disturbance limitations, regardless of calculation of disturbance allowances for purposes of determining replacement planting requirements:
a)
Classes I and II, and woodland corridor or riparian corridor. Permitted woodland disturbance on any lot or tract shall not exceed 15 percent of any area designated Class I or Class II woodland, or any other woodland within a designated woodland corridor or riparian corridor on the Kennett Township Woodlands Classification Map and Woodland and Riparian Corridors map, except that, within C, LI, RMHD, V-H, and V-M Districts, such permitted disturbance may be increased to up to 40 percent.
b)
Class III and other woodlands. Outside of areas designated as woodland corridor or riparian corridor of § 240-1802.F.2.b.1)a), permitted woodland disturbance on any lot or tract shall not exceed 25 percent of any Class III woodland or any other unclassified woodlands or hedgerow(s) on the Kennett Township Woodlands Classification Map. This limitation shall not apply in C, LI, RMHD, V-H, and V-M Districts.
c)
Interior woodland. Permitted woodland disturbance on any lot or tract shall not exceed ten percent of any area designated as interior woodland on the Kennett Township Woodlands Classification Map.
d)
Disturbance limitations shall be measured based on the extent of the subject woodland classification at the time of first submission of applicable application(s) after the adoption of this section and shall be indicated on applicable plan(s) or permits. Any disturbance limitation shall run with the land, once established. Subsequent applications shall be subject to the initial determination of disturbance limitations, regardless of intervening disturbance which may have occurred. If at any time within three years prior to an applicable application there had existed a greater extent of woodland, such greater area shall be utilized to calculate the extent of woodland disturbance and the limitations set forth herein.
2)
Where disturbance to existing areas of woodlands and hedgerows exceeds standards set forth in the Subdivision and Land Development Ordinance, woodland replacement shall be required consistent with required vegetation replacement of said ordinance. Determination of the extent of woodland disturbance shall be as described in said ordinance.
3)
Guidelines for disturbance. When determining where permitted woodland disturbance will occur, the following factors shall be considered:
a)
The applicant shall consider the location(s) and benefit of conservation of healthy mature woodland stands and the classification of the woodland as shown on the Kennett Township Woodlands Classification Map.
b)
Each building or structure shall be constructed in such a manner as to provide the least alteration or disturbance necessary of the existing woodland. Clear-cutting shall be minimized, and trees shall be selectively removed.
c)
In each situation where the standards of this Section are applied, consideration shall be given to balancing the benefits of woodland preservation with other valuable resources on the site, including scenic views. The Township shall consider woodland disturbance where limited disturbance may permit siting of buildings in less visually obtrusive areas of the tract.
d)
The remaining undisturbed woodlands and other vegetation shall interconnect with woodlands or wooded areas of adjacent properties to preserve continuous woodland corridors and allow for the normal movement, dispersion, and migration of wildlife. The applicant shall consider the impacts, in terms of functions and values to wildlife, of separating, dividing or encroaching on wildlife travel corridors or extensive habitat areas, especially woodlands exceeding ten acres in area.
4)
Protection of woodlands to remain on-site. Woodlands, hedgerows, individual trees, specimen vegetation, heritage trees, and other vegetation that is to remain on the site shall be identified on the plan and protected from land disturbance and construction activities per the tree protection provisions of the Subdivision and Land Development Ordinance. In addition:
a)
Preserved woodlands and hedgerows may be used to provide the vegetative screens and buffers required by Article XX. Where necessary to meet the intent and minimum standards of such, additional planting may be required to supplement existing vegetation.
b)
Provisions for the long-term management of woodland areas not subject to woodland disturbance shall be consistent with the woodland management planning requirements of the Subdivision and Land Development Ordinance.
