Full Breakdown

Under Town Code § 322-101, the Town Board may authorize a density bonus of up to five units per acre added to a Retirement Community (RC) Zoning District after a public hearing noticed the same way as other special exceptions under § 322-94. Before granting it, the Board must confirm the site has reasonable access to mass transit and local shopping, sits at least 500 feet from any Light Industry or Heavy Industry District, fronts on a state, county or Town arterial road, and holds buildings no taller than two stories measured from at least two corners.

Gross floor area on the site cannot exceed 35% of the site area, a cap added by a 1988 amendment. One manager's apartment per 50 bonus apartments (or fraction thereof) is allowed on top of the density otherwise permitted under § 322-19B. S. Census Bureau or HUD, and rent for those units must stay below 30% of the median income of low-income senior citizens under the same federal classifications. Applicants must back this up with a restrictive covenant or comparable recorded agreement approved by the Town Board guaranteeing the units stay affordable, plus a graphic site analysis and scaled site plan under Article XIII covering steep slopes, drainage, groundwater depth, soils, vegetation, wildlife, wetlands, and historic or scenic resources. The Board retains discretion to impose additional conditions before granting the exception.

Violations & Fines

Violations of the RC density-bonus conditions are enforced as zoning violations under § 322-106. A first conviction carries a fine of $500 to $5,000; a second conviction within five years of the first carries $2,000 to $10,000; a third or subsequent conviction within five years becomes a misdemeanor punishable by $4,000 to $15,000, up to six months' imprisonment, or both. Each day a violation continues after Town notification or service of a summons is a separate offense, and the violator also owes the Town's costs of pursuing the case. The Town Attorney may additionally seek civil penalties up to $500 per day, injunctive relief, or an action to compel compliance.
