Have a minimum rear yard setback of 20 feet. Decks and patios may encroach into the twenty-foot setback by 10 feet.

The minimum habitable floor area for a townhouse unit may be reduced to 1,450 square feet provided that no more than 33% of the total townhouse units shall be permitted to be less than 1,700 square feet (in other words, at least 67% of the townhouse units constructed shall be 1,700 square feet each or more based upon the minimum habitable floor area). Smaller townhomes shall be intermixed with the larger townhomes.
(3)
A townhouse gross density development in the R-3 shall consist of at least 125 townhouse units but shall not exceed 185 townhouse units - this is based upon the allowable floor areas, parking spaces and related density of units.
(4)
There shall be no more than six townhouse units in any group of connected townhouses (each group of connected townhouse units shall be referred to as a "townhouse building"). Up to three townhouse buildings shall be permitted to consist of only two units without being defined as twins.
(5)

Each townhouse shall have the exclusive use of at least two parking spaces (inclusive of interior garage spaces). Each required parking space not for the exclusive use of a townhouse unit shall be separated from the townhouse unit for which it is required by no more than 230 feet.
(6)
All parking areas shall be set back a minimum of 20 feet from existing street rights-of-way.

(a)
Street trees, at intervals of at least 80 feet, on both sides of all proposed street rights-of-way within the tract; however, trees may be situated in other viable locations (including offsite) upon review by the Borough Engineer and approval by the Borough provided that the number of total trees equals what would be required if the trees were set at least 80 feet apart on both sides of all proposed street rights-of-way within the tract.
(b)
Where feasible, a continuous vegetative screening between the tract boundaries, and the townhouse buildings and associated improvements. Such vegetative screening shall comply with the requirements set forth in § 430-67C of the Zoning Ordinance and may incorporate the existing woodlands areas that are not disturbed during development in order to satisfy screening requirements.
(8)
An open space/recreation area plan shall be provided as part of the conditional use application and guided by the provisions set forth in § 375-32 of the Borough's Subdivision and Land Development Ordinance as part of the Borough's Code of Ordinances.

§ 430-27.2 Height regulations.
No building shall exceed 35 feet in height, provided that such height limit may be exceeded by one foot for each foot by which the width of each side yard is increased beyond minimum side yard requirements, up to a maximum height of 45 feet. Accessory structures shall not exceed 16 feet in height.
§ 430-27.3 Parking.
Except for townhouse gross density development, parking shall be provided in accordance with § 430-72, Off-street parking.
