The Highlands RMP establishes Highlands Resource Areas and Special Protection Areas, each delineated based on the existence of one or more significant Highlands resources or critical or sensitive environmental characteristics or features. The Clinton Township Master Plan incorporates each of these areas to the extent of their physical limits within the municipality, and the specific policies, goals and objectives relating to their protection as an integral component of the planning and land use policies of the municipality. In keeping with the Clinton Township Master Plan, the Highlands Resource Areas and Special Protection Areas present in the Township, including any not specifically identified in the Township's Highlands LUO, are herewith established as overlays to municipal zoning.
A. 
Highlands Open Waters and buffers. All Highlands Open Waters shall include a minimum 300-foot-wide protection buffer, as measured from the edge of the Highlands Open Waters feature indicated in the Highlands Region Interactive ERI at https://www.highlandseri.com/.
(1) 
No disturbances of Highlands Open Waters are permitted except where previously approved by the Highlands Council.
(2) 
Highlands Open Waters buffers shall be maintained in their undisturbed or pre-existing condition, unless a disturbance is approved in accordance with following:
(a) 
Where a NJDEP a Letter of Interpretation (LOI) or Highlands Resource Area Determination (HRAD) has been issued delineating the location a wetland, the boundaries of said wetland as identified shall govern. However, the buffer shall be 300 feet irrespective of the buffer identified in the LOI.
(b) 
With respect to any wetlands and other Highlands Open Waters features not mapped on the Highlands Region Interactive ERI at https://www.highlandseri.com/, each shall include a 300-foot wide protection buffer measured from a delineated wetlands line described in a LOI, from a field-delineated boundary line for other features, or as indicated by a Highlands Resource Areas Determination (HRAD) issued by the NJDEP.
(c) 
Any lawful pre-existing structure or improvement located within a Highlands Open Waters protection buffer area may remain and be maintained or rehabilitated, provided that the existing area of disturbance attributed to or associated with such structure or improvement shall not be increased.
(d) 
Disturbances of Highlands Open Waters buffers located in the Existing Community Zone are permitted in previously disturbed areas as follows:
[1] 
Agricultural and horticultural land uses. For purposes of Highlands Open Water buffer disturbances in the Existing Community Zone, existing agricultural and horticultural uses, whether or not under active management or operation, shall not be considered "previously disturbed" buffer areas with regard to uses for non-agricultural development.
[2] 
Any disturbance in a previously disturbed buffer must be accompanied by the finding that there will be no net loss of functional value of the buffer. This may include the use of mitigation and restoration of the Highlands Open Water Buffer. If existing land uses create a natural or developed barrier to the buffer, then the buffer may be considered to be developable.
(e) 
Disturbances of Highlands Open Waters buffers located in the Protection and Conservation Zone are permitted in previously disturbed areas but in no case shall the remaining buffer be reduced to less than 150 feet from the edge of Highlands Open Waters.
[1] 
Agricultural and horticultural land uses. For purposes of Highlands Open Water buffer disturbances in the Protection and Conservation Zone, existing agricultural and horticultural uses, whether or not under active management or operation, shall not be considered "previously disturbed" buffer areas with regard to uses for non-agricultural development.
[2] 
Any proposed disturbances must demonstrate full utilization of the following performance standards in the listed order, to demonstrate the necessity of an encroachment into Highlands Open Waters buffers:
[a] 
Avoid the disturbance of Highlands Open Waters buffers;
[b] 
Minimize impacts to Highlands Open Waters buffers; and
[c] 
Mitigate all adverse impacts to Highlands Open Waters buffers so that there is no net loss of the functional value of the buffer.
B. 
Riparian Area standards. Disturbance of any portion of a Highlands Riparian Area, as shown in as depicted on the Highlands Region Interactive ERI at https://www.highlandseri.com/, in the Protection Zone is prohibited except for linear development, which shall be permitted only where it has been shown that there is no feasible alternative for the linear development outside of the Riparian Area.
(1) 
To address the "no feasible alternative for linear development" standard, the applicant shall demonstrate that there is no other location, design or configuration for the proposed linear development that would reduce or eliminate the disturbance of Riparian Area.
(2) 
For proposed linear development that would provide access to an otherwise developable lot, the applicant shall, in addition, show that:
(a) 
The proposed linear development is the only point of access for roadways or utilities to an otherwise developable lot; and
(b) 
Shared driveways are used to the maximum extent possible to access multiple lots.
(3) 
An alternative shall not be excluded from consideration under this subsection merely because it includes or requires an area not owned by the applicant that could reasonably be obtained, utilized, expanded, or managed in order to fulfill the basic purpose of the proposed linear development.
A. 
The location, extent and type of Critical Wildlife Habitat, Certified Vernal Pools and Natural Heritage Priority Sites are those areas defined in Article XLI, Definitions, and identified by the NJDEP. Details on the areas may be found on the Highlands Council's interactive map or through the NJDEP.
B. 
Critical Wildlife Habitat.

A Critical Wildlife Habitat area may be disturbed where a Habitat Suitability Analysis conducted by a qualified professional has been submitted to the Land Use Board, which shall review and confirm findings that:
[1] 
The nature of the site is such that it does not provide habitat for species of concern;
[2] 
The species of concern are not present on the site during any critical part of their life cycle, do not depend upon the site for food, shelter or breeding, and the habitat or the site is either unsuitable or not critical to species' recovery in the region; or
[3] 
Existing land uses present a human, natural or development barrier to the use of the site by species of concern.
(b) 
Avoidance of disturbance to species of concern can be achieved through adherence to commonly accepted, species-specific timing restrictions, including but not limited limitations on the timing of tree clearing, site disturbance and project development.
(2) 
Where disturbance of any Critical Wildlife Habitat has not been confirmed to be in accordance with the above standards, no disturbance shall be authorized without prior written approval of the Highlands Council.
C. 
Certified vernal pools.
(1) 
Certified vernal pools as regulated in this section are depicted on the Highlands Region Interactive ERI at https://www.highlandseri.com/.
