The minimum size of a tract of land proposed for development under the lot cluster development provisions of this article shall be 20 acres.

Land area equal to a minimum of 25% of the tract of land proposed for development shall not be included in building lots but shall be set aside for conservation, open space, recreation and park area or similar purposes, not including street rights-of-way, driveways, parking areas, utility stations and buffer strips.

The open space area saved shall be permanently devoted to one or more of the following open space uses: woodland conservation areas, game preserves, wild fowl refuges, pedestrian walkways, cycling (excluding motorized cycles) and bridle trails, stream preservation, watershed protection, flood control areas, parks, playgrounds and ball fields.

Prior to any final approval, an open space organization shall be established pursuant to Article XV of Chapter 17, Land Development Review, of the Code of the Borough of Lincoln Park to own and maintain common open space areas established pursuant to this article or such common open space areas shall be dedicated to and accepted by the Borough.

Not in excess of 50% of the total open space of the area required in Subsection B above shall be located in any one or any combination of the following: a floodplain having an existing grade four feet or more below the base flood elevation, floodways, areas with a slope greater than 15%, watercourses or bodies of water or areas deemed unsuitable for recreational purposes due to environmental reasons.

While nothing herein contained shall be deemed to require that as a condition of lot cluster development project approval a developer must make available lands for public use which are proposed as open space, the Borough may, at any time and from time to time, accept a voluntary dedication of said land or any interest therein for public use and maintenance, provided that such dedication shall not prohibit the installation of underground public utilities.

No building or structure shall be located within 75 feet of any development boundary line, provided that 50 feet of such area may be utilized as any required buffer strip.

A buffer strip of at least 50 feet in width shall be provided along any zone boundary line except where a residential lot cluster development abuts an R-15, R-20 or R-40 Zone. The municipal agency may require a buffer strip in excess of 50 feet for good planning reasons, including but not limited to the need to additionally buffer uniquely sensitive areas having ecological, historical or archaeological significance, fully taking into consideration the tract size, the total quantum of land devoted to the required buffer strip, the effect thereof upon the development proposal and the impact upon surrounding properties.

The lot cluster subdivision development plan shall not result in a greater average gross density than if the property in question were developed without residential lot clustering.

The common open space shall be reserved in perpetuity by dedication for public use or by private covenant or by deed restriction in conformance with Article XV of Chapter 17, Land Development Review, of the Code of the Borough of Lincoln Park for use by the residents of the development for one of the following purposes:
