A Senior Residential Development shall be designed to provide housing options in a setting that encourages and supports aging in community.

Structures shall be clustered to reduce site disturbance and protect open spaces, natural and environmentally sensitive areas.

Building design shall avoid use of long, unbroken facades, and shall include use of balconies, offset walls, trellises and other design elements to provide visual interest.

Building design, colors, and materials shall generally correspond to the natural setting of the project site, and to any prevalent design styles that may occur in neighborhoods within the general project area.

The development shall be served by public water.

The special permit application, public hearing, and decision procedures shall be in accordance with this article, the Planning Board's Rules and Regulations, and § 173-7 of this Zoning Bylaw.
