Table of Performance Regulations.

The purpose of providing for the development of twin or townhouse units in the R3 Zone is to provide flexibility and a variety of housing types and to encourage a subdivision design approach that considers the environmental and physical attributes of a site, the site's relationship to the surrounding area, and the most desirable and appropriate locations for home sites. The allowance for single-family homes, twin/duplex units, and townhouse units on relatively small lots enables planned residential development that will balance developed areas with the protection of wooded and environmentally sensitive areas on a site. The cluster provisions allow residential developments to be constructed at a lower cost per dwelling for streets, utilities and other site improvements, while also providing recreational opportunities that are appropriate to the needs of and convenient to the residents of the Borough. The cluster provisions may reduce the amount of clearing, grading, and construction disturbance resulting from subdivisions and increase the quantity and quality of open spaces, providing a desirable residential environment through creative development techniques and design arrangements.

Conservation or open space areas should be centrally located and adjoin as many residential lots as practical in order to increase the value of the lots and provide for the enjoyment of open space by as many residents as possible. A conservation or recreation easement restriction shall be placed on open space areas to ensure that the land will be preserved in perpetuity.

All open space areas must have a minimum street frontage of 100 feet to ensure access for residents of the development and for maintenance.

In order to ensure variety among single-family residential dwellings, houses on the same side of the street must be substantially different in appearance than other dwellings within two lots from it. On a cul-de-sac, any lot on the cul-de-sac is considered to be on the same side of the street. All major subdivisions for single-family homes must provide a minimum of three basic house designs with exterior variations possible for each one.

For all residential units variations in rooflines, heights, projections, and exterior building materials shall be incorporated to distinguish the residential units and add interest.

The architecture of units with frontage on two streets shall respond to both streets, with architectural details, windows and other elements that respond to the street frontage.

For townhouses, if trash and recyclables will be stored in common areas, then a trash enclosure shall be provided with sufficient space for trash and recyclable materials. The enclosure must be constructed of masonry with facade materials to match the buildings, must be a minimum of six feet high, and surrounded by a landscape buffer on three sides. A pedestrian entrance to the enclosure must be provided so the gates are not frequently left open.

Each townhouse unit must have a garage with sufficient space for a vehicle and for storage of trash and recycling containers (if applicable) and other incidental personal items such as bicycles. A deed restriction must prohibit the conversion of the garage to living space.

Rear yard decks may encroach into the required rear yard by a maximum of 10 feet. For example, if the required rear yard is 30 feet, then an attached deck may be set back a minimum of 20 feet.

Rear yard fencing must be consistent in style and color among all residential units in a twin/duplex or townhouse development.

For townhouses, in addition to RSIS parking requirements for the residential units, a shared parking area or on street parking for guests to accommodate a minimum of 0.3 vehicle per residential unit shall be provided.

Lots that have been previously subdivided (via minor subdivision or final major subdivision) and that have been filed and recorded at the County Clerk's office prior to the effective date of this section, and lots that have been approved and developed with multifamily residential units prior to the effective date of this section, and that were compliant with the zoning requirements prior to the effective date of this section may continue to exist as a conforming lot or use.

For existing dwellings in the R-3 District, or for individual infill lots in the R-3 District, the front yard requirements are as follows:
