Common open space criteria.

Up to 20% of the common open space may be devoted to paved areas or structures used to provide recreational or cultural facilities for the residents of the cluster development consistent with the intended use of the common open space.
(2) 
Wetland areas as delineated by the State of Rhode Island shall not be counted toward the 30% required open space for cluster developments. Wetland buffers may be included to meet this requirement.
(3) 
The location, size and shape of common open space shall be reviewed and approved by the Planning Board. Strips of common open space are not permitted unless they provide access to a large portion of common open space, serve as natural drainage areas, or serve as buffers.
(4) 
Access to common open space shall be provided to every owner of the common open space. Access points shall be marked by stone bounds to distinguish between the edge of the access and private property.
(5) 
Land which has suffered environmental damage, either on the surface or below the surface, prior to the final approval of the cluster development by the Board shall not be counted toward common open space requirements. Should the land be restored to a condition acceptable to the Planning Board, this condition may be waived upon approval by the Zoning Board of Review.
(6) 
As per the requirements of Chapter A263, Development and Subdivision Review Regulations, a conveyance of land or fee may be accepted by the Town to meet anticipated recreational needs generated by the cluster development proposal. In the event that land is conveyed, such area shall not be counted toward meeting the requirements for common open space under this article.
