J. 
Rural residential planned village clusters, subject to the following requirements and conforming to the findings of a planned development as defined by the Municipal Land Use Law, N.J.S.A. 40:55D-45, and in accordance with an approved general development plan.
(1) 
The minimum total area to be developed as a rural village cluster shall be 150 acres. Such area shall be developed in accordance with a single comprehensive general development plan. Streets shall not be deemed to divide acreage for the purposes of this requirement.
(2) 
For rural village cluster developments located in the R-150 Zoning District, the maximum number of permitted lots shall be determined by multiplying the net developable acreage of a tract, after exclusion of environmentally constrained areas and public rights-of-way, by 0.3 dwelling units per acre and multiplying the net acreage of environmentally constrained areas and public rights-of-way by one hundred 0.166 dwelling units per acre and adding the resultant figures to establish the maximum number of lots. "Environmentally constrained areas" shall include areas designated as wetlands, one-hundred-year flood hazard areas, water bodies and public rights-of-way. Detailed soil engineering and geotechnical test data undertaken in accordance with acceptable engineering standards and practices may be submitted by an applicant if he seeks amendment of the boundary limits established by state and federal regulatory agencies which define such environmentally constrained areas.
(3) 
No less than 75% of a rural village cluster development shall be devoted to agricultural, conservation, open space and/or recreational purposes. All one-hundred-year flood hazard areas and wetlands shall be permanently restricted for open space. Individual residential lots or portions thereof shall not be construed as open space. Designated agricultural, conservation, open space and/or recreational areas shall be in major contiguous parcels and shall be interconnected with similar areas on abutting tracts and parcels, having adequate access to public and/or private roads and in some cases consisting of land developed for specific recreational purposes. Conservation, open space and/or recreational areas shall also be interspersed within the village cluster development. Open space may be used for sewage disposal systems using techniques conforming to applicable environmental and engineering standards. "Open space areas," for purposes of this calculation, shall not include, among other things, courtyards, cul-de-sac islands and miniparks.
(4) 
All dwelling units associated with rural village clusters shall be required to locate within housing areas identified on the Plainsboro Township Land Use Map.[1]
[1]
Editor's Note: A copy of this map is on file in the office of the Township Clerk.
(5) 
Recreational facilities and open space.
(a) 
Active recreational facilities may be provided in a rural village cluster development, subject to the review and approval of the Planning Board. Such recreational facilities may be jointly provided by two or more developers within the R-150 Zone with convenient access to all users, provided that the facility and/or recreational area shall equal the recreational requirements of the participating properties served. The location of such recreational facilities shall be carefully planned to provide privacy for the users and to avoid problems of noise, lighting and similar nuisances which might interfere with their use and enjoyment by residents of the development.
(b) 
The design and use of open space areas interspersed among groupings of residential dwellings shall protect the natural resources and qualities of the site, including the natural terrain, woodlands, significant views and any unique and unusual features. Open space other than that preserved for its natural values shall be suitably landscaped. All structures within open space areas shall be sited so as to retain their visual appeal. The Planning Board shall require such grading, drainage, planting, walkways, fencing, lighting and such other improvements in the common open space as may be necessary to enhance the intended open space and recreational uses.
(6) 
To the maximum extent practicable, rural village clusters shall be located on land not well suited for agricultural purposes because of size, location, proximity to neighboring land uses, existing tree mass, access, shape, quality of soil and drainage. The design and location of rural village clusters shall give priority to protecting the most suitable soils for subsurface septic disposal (in unsewered areas only); to leaving prime agricultural soils for agricultural uses; to avoiding environmentally constrained areas; to locating dwellings along wooded areas to reduce impacts upon agriculture, to provide summer shade and shelter from winter wind and to enable new residential construction to be visually absorbed by natural landscape features; to not blocking or interrupting scenic vistas, as seen from the public roadways; to locating dwelling units and other improvements on the lower-quality agricultural soils.
(7) 
The Planning Board shall permit the subdivision of all existing, at the time of ordinance adoption, single-family detached dwelling units with accessory uses and/or farm buildings to be located on a minimum lot size of one acre as part of the comprehensive development plan for the village cluster development.
(8) 
The applicant for a rural village cluster development shall execute such statement for prospective homeowners as the Planning Board requires, which recognizes that the applicant is aware of the purposes and requirements governing the R-150 Zone; that the applicant and prospective homeowners are aware that certain disturbances and annoyances arising from usual commercial agricultural activities can reasonably be expected to occur seasonally, both during the day and night; and that, in consideration for being granted the right to construct or occupy a nonfarm single-family dwelling in the zone, the applicant hereby waives, on behalf of himself, his heirs, successors and assigns, all right to object to such reasonable commercial agricultural activities.
(9) 
When the major purpose of the rural village cluster is to preserve open space for agricultural and farming purposes, all dwelling units shall be located and constructed at such places on the tract and in such a manner that, to the greatest extent possible, they shall not segment land of any one farm into awkward or odd-shaped parcel sizes difficult to support viable farming operations, nor interfere with the conduct of agriculture, on- or off-site, by limiting or interfering with the access to fields or the effectiveness and efficiency of the farmer and farm equipment, including crop-spraying aircraft.
(10) 
The following minimum design, bulk and area requirements shall apply to the development of a rural village cluster:
(a) 
The Planning Board shall determine the total number and location of clusters at the time of general development plan review.
(b) 
Land used for agricultural use shall be provided access for farm equipment that does not interfere with rural village cluster vehicular access.
(c) 
A development tract's existing road frontage shall not be totally subdivided into residential lots.
(d) 
Impervious surfaces, in the aggregate, shall not cover more than 40% of the net residential land (as defined above) of the tract.
(e) 
All residential lots shall be serviced by a public centralized water system and either a public sewer, community septic system or individual septic systems, upon a demonstration that such individual systems are permitted under state law and New Jersey Department of Environmental Protection policy.
(f) 
No habitable dwelling unit area shall be constructed below grade if the Township Engineer determines water problems will result from existing soil limitations. Units shall be designed in such a manner as to provide maximum security and visual privacy from adjacent units.
(g) 
Twenty thousand square feet shall be the minimum lot area for a residential lot The average lot area, including one dwelling, its accessory uses and private open space, shall not be less than 25,000 square feet.
[1] 
Frontage. The minimum street frontage shall be 125 feet.
[2] 
Lot width. The minimum lot width shall be 125 feet.

[6] 
Rear yard. The minimum rear yard depth shall be 30 feet.
[7] 
Building height. The maximum building height shall be 35 feet.
(h) 
The minimum lot frontage shall not be less than specified above unless a lot adjoins a cul-de-sac or is on a curved roadway alignment or is otherwise odd-shaped, in which case the minimum lot width shall be measured at the front setback line.
(i) 
New streets shall be constructed to service rural village cluster developments instead of subdividing new lots along existing minor arterial, major collector and minor collector roadways within the R-150 Zone. In a subdivision abutting arterial or collector roadways, the frontage shall be reversed so that the lots contiguous to such streets will front on the newly-created collectors, local streets or cul-de-sacs, with an additional lot depth of 50 feet over and above bulk and area regulations. This additional lot depth shall be a conservation easement used exclusively for planting, screening and landscaped earthen berms to be provided by the developer and maintained by the lot owner or by a homeowners' association, if one is created.
(11) 
Land permanently set aside for agricultural, conservation, open space and/or recreational uses may either be offered for dedication to Plainsboro Township, deed-restricted to remain with the original property owner, dedicated to a nonprofit organization found acceptable to the Township Planning Board and/or protected by a homeowners' community association. An open space which is not accepted for public use by the Township Committee shall be protected by legal arrangements satisfactory to the Planning Board sufficient to assure its maintenance and preservation in perpetuity for its intended purpose. Covenants or other legal arrangements shall specify ownership of the open space; method of maintenance; responsibility for maintenance; maintenance taxes and insurance; compulsory assessment provisions; guaranties that any homeowners' association formed to own and maintain open space will not be dissolved without the consent of the Planning Board; and any other specifications deemed necessary by the Planning Board. The open space left unbuilt upon after development shall be maintained in accordance with a land management plan prepared by the developer and accepted and approved by the Planning Board. The developer shall provide copies of deed covenants with prospective purchases, or conservation easements with the Township, describing land management practices to be followed by party or parties that are responsible for open space. Further subdivision of open space land, or its use for other than agriculture, conservation and recreation, shall be prohibited.
(12) 
Within open space areas the Planning Board may require the developer to make certain site preparation improvements, which may include but are not limited to the following:
(a)

(13) 
Notwithstanding anything in Subsection J(11) hereof to the contrary, land designated as agricultural, conservation or open space may be incorporated into private lots which conform to this article upon approval by the Planning Board that such land will be permanently protected from development as an alternative to dedication or protection by a homeowners' community association.
(14) 
Any rural village cluster development shall be buffered from adjoining agricultural lands to create an effective dense barrier separating yards and fields and pastures, to ensure that the continuation of agricultural operations in the area will not be impaired by nuisance complaints. The buffer shall, inasmuch as possible, be a natural one. The dimensions of the buffer area and its treatment with landscaping, natural berms and/or fencing shall be subject to review and approval by the Planning Board. Additionally, there shall be a buffer area separating the village cluster from adjacent streets and residential areas. The dimensions of the buffer area and its treatment with landscaping, berms or fencing shall be subject to review and approval by the Planning Board. However, as a minimum, the buffer area along all lot and street lines shall be 50 feet wide.
(15) 
No preliminary approval shall be granted for any subdivision or site plan in connection with the development of a rural village cluster unless the Township Health Officer and Township Engineer have approved plans for potable water supply and sewage disposal to serve the development.
(16) 
All historic buildings, as identified on the Middlesex County Inventory of Historic, Cultural and Architectural Resources, located within a rural village cluster development shall be permanently protected and reused by the developer, to the extent feasible, in conformance with requirements received from the Planning Board.
(17) 
Flexibility and variety in lot and building layout, roadway construction, utility design and other site improvements shall be encouraged to best relate the improvements to the land. To that end, lots, buildings and utilities shall be designed so as to minimize the alteration of the natural terrain and fit into the rural, agricultural and open space environment of the R-150 Zone.

Any person desiring to subdivide and/or otherwise develop property in the R-150 Rural Zone may elect to apply to the Planning Board for major subdivision under the following reduced improvement requirements of this section with all other major subdivision requirements applying. The Planning Board shall examine each request to determine whether it meets the following minimum standard requirements:
(1) 
The design of the development shall blend with the agricultural, open space and rural atmosphere of the R-150 Zone.
(2) 
The development shall not adversely affect the development of adjacent or adjoining property.
(3) 
Proposed local streets shall not interconnect with existing or proposed streets in other classifications to form a continuous route. They will be designed to discourage any through traffic, will have the exclusive function of providing access to properties abutting the street and will follow the contours of the land to the greatest extent possible.
(4) 
The development shall provide for off-site pedestrian and bikeway interconnections with other residential developments and public facilities, e.g., schools and parks.
B. 
If it is determined by the Planning Board that the proposed development conforms with the minimum standards listed in Subsection A above, the following reduction in standards and improvements may be allowed by the Board:
(1) 
The maximum street right-of-way shall be 40 feet, and the cartway shall be 24 feet with stabilized grass shoulders, only if the applicant provides for adequate amounts of off-tract homeowner and visitor parking.
(2) 
Private driveways may be constructed of gravel or another porous material.
(3) 
All utilities shall be installed underground.
(4) 
Surface stormwater runoff may be carried in open swales within or outside the street right-of-way to appropriately located storm inlets as approved by the Township Engineer.
(5) 
Curbs and gutters shall not be required except where excessive grades, drainage considerations or other site conditions require their installation.
(6) 
The concrete sidewalk requirement may be waived under certain conditions. In lieu of concrete sidewalks along one side of a street contained within a subdivision, a five-foot-wide pedestrian walkway of bituminous asphalt or other material acceptable to the Township Engineer, installed along one side of a comprehensive walkway network within the subdivision providing access to individual lots and located outside of a street right-of-way, may be permitted.
(7) 
The maximum length of a cul-de-sac measured from an intersecting street center line to the center point of the closed end of the cul-de-sac shall not exceed 1,500 feet.
C. 
The following criteria shall be utilized by the Planning Board during subdivision reviews within the R-150 Rural Zone where it is determined that utilization of a rear-lotting technique is justified by the Board.
(1) 
Access to the rear lot may be through an access strip held in fee simple ownership, not through an easement over adjacent property.
(2) 
The body of the lot, exclusive of the access strip connecting it to a street, shall have an area and dimensions meeting the minimum requirements for the zone.
(3) 
The access strip shall be continuous and under the same ownership as the proposed rear lot.
(4) 
The intersection of the access strip with a street shall be such that access to and from the street, and the improvement and use of the access strip along the full course of the access strip and proper sight triangles, as well as the drainage and other site considerations, shall be provided in a manner not adversely affecting the remainder of the tract or adjoining properties.
(5) 
The proposed subdivision shall not adversely affect the development of the remainder of the parcel.
(6) 
In the event an additional lot or use is proposed, and said additional lot can only achieve access via the access drive of the flag lot, the owner of the access strip shall, at his expense, pave and improve it in accordance with Township standards. Such road improvements shall be made prior to the issuance of a building permit for the additional structure. This shall not prevent the access drive to the flag lot from serving abutting lots that otherwise have street frontage.
(7) 
No more than two access strips shall be contiguous. The spacing and ultimate number of access strips shall be determined by the Planning Board during the subdivision review and approval process.
Lots in the R-150 Zone which were conforming at the time they were created will be considered conforming lots if they are at least 35,000 square feet in size.
