[Amended 1-28-2004 by Ord. No. 742]
Cluster residential development may be permitted (in accordance with the permitted uses in each zoning district and the Schedule for District Regulations for Maximum and Minimum Building Standards), in all zoning districts, subject to the following standards and requirements:
A. An open space cluster requires that a percentage of the land area of the tract involved be permanently preserved as open space and may include active or passive open space. Passive open space may include lands preserved for the environmental sensitivity.
B. All tracts of land 40 acres or greater in size either at the time of the adoption of this chapter or that are assembled after the adoption of this chapter shall be eligible for cluster residential development, provided the application meets the following requirements:
(1) Land area equal to a minimum of 50% of the total tract of land proposed for development shall not be included in lots but shall be set aside and deed restricted for open space and recreation.
(2) The Land Use Board shall determine what percentage, if any, shall be used for one or more of the following active recreational purposes: golf courses with accompanying clubhouses and facilities; swimming pools and cabana clubs; tennis, badminton, volleyball, and basketball courts; playing fields; riding clubs; limited membership outdoor recreational areas; or private landscaped areas under the supervision of a homeowners' association as provided for in this section.
(3) The remaining portion of open spaces saved shall be permanently devoted to one or more of the following open land uses: parks or playgrounds, woodland conservation areas, game preserves, wildlife refuge, pedestrian walkways, bicycle paths and bridle trails, stream preservation, and watershed protection or flood control areas. An application for a cluster development shall clearly identify all open space areas and its proposed land uses.
(4) Land utilized for street rights-of-way, driveways, parking areas, courtyards, utility stations, and loading areas shall not be included as part of any above-referenced minimum 50% open space set aside.
(5) Not more than 50% of the total open space saved shall be located in one or more of the following: a floodplain, areas with a slope greater than 10%, watercourses or bodies of water, wildlife habitats or other areas deemed unsuitable for development and recreational purposes due to environmental reasons as made evident by the review of the environmental impact statement, where required.
(6) The location of proposed lots, streets, utilities, and active recreational areas shall be adjacent to other similar developed areas to the greatest extent possible thereby maximizing the clustering of development. Proposed development layout or design shall be found to meet this requirement as a condition of attaining approval.
C. Planned residential cluster developments as permitted shall require an environmental impact statement.
D. Provisions made within any planned residential cluster development for open space and recreational areas shall be reviewed, found adequate, and approved by the Land Use Board. In its review, the Land Use Board shall investigate the size of parcel devoted to open space and recreational areas; their location within the project; the topography; the uses contemplated upon such open space and recreational area; configurations of the parcels under consideration; facilities and improvements to be provided; the provisions made for maintenance and access to said parcels or facilities; traffic flows to and around said parcels; the ecological impacts of their placement, development and use; the staging or timing of the open space or recreational area development, and how various categories or recreational facilities or open space and their location will be proportionally related to the staging of the development of housing units, if such staging is proposed.
E. The Land Use Board shall make detailed findings concerning the adequacy or inadequacy of the aforesaid items to be reviewed in determining their conformity with the provisions of this chapter, the adopted Township Master Plan, and any other plans or regulations applicable or relevant to the lands involved. The provisions made shall be deemed adequate if the Land Use Board determines that:
(1) Portions of the open space and recreational areas are readily accessible to all residential dwelling units.
(2) The uses being designated for open space and recreational areas are reasonably related to and appropriate and sufficient to meet the needs of the project's residents for a variety of uses appealing to the anticipated residents of the proposed development, considering differences in age, income level, and interest.
(3) The uses designated for open space and recreational areas will be functional upon the arrival of the residents who will use them.
(4) The topography and environmental character of the land is suitable for the uses proposed, and the uses will not cause unreasonable adverse impacts to the ecology of the area incapable of being mitigated.
(5) The open space and recreational areas are conveniently and appropriately designed with regard to the project's pedestrian and vehicular traffic patterns, to provide adequate access to, in, around, and from the uses proposed.
(6) While nothing herein contained shall be deemed to require that, as a condition of development approval, a developer must make available lands for public use which are proposed for open space and recreational areas, the Township may, at any time and from time to time, accept the dedication of said land(s) or any interest therein for public use and maintenance where a free and noncoerced offer is made by the developer or owners of said land(s).
F. All cluster developments shall be considered to be planned developments and major subdivisions subject to subdivision review and approval. In addition to all regulations herein contained in this section, cluster development applications shall also require the Land Use Board find that:
(1) The proposed development, its design and layout, and its size will not be detrimental to the surrounding neighborhood or to the intent and purposes of this chapter or the adopted Township Master Plan. Furthermore, the design shall be such that the use of the clustering achieves maximum benefit in the use of land, presentation of open space, and good development design principles and techniques;
(2) An environmental impact statement has been required, reviewed, and found to determine that, as proposed, the development will not unreasonably adversely affect the environment of the lands upon which it is to be located or those adjacent thereto, or to create reasonably demonstrable adverse impacts off site; and
(3) Cluster development as proposed will create a residential project harmonious with its environment and surrounding development.
