Islip, NY Zoning Overlays & Bonuses: Downtown Design Guide (2026)

3 lists the specific Suffolk County tax parcels the Town Board has mapped into DDDs, starting with Downtown Bay Shore. 1's legislative intent, added and amended through ordinances running from 1976 to 2008, ties the district to eight specific purposes: more efficient use of hamlet centers, coordinated public facilities, a broader range of housing choices, reduced car dependence by locating housing near transit and jobs, pedestrian circulation and access to amenities, a balance between nature and development that preserves views and visual corridors, incentivizing development consistent with the Comprehensive Plan, and, the clause most relevant to design review, promoting adaptive reuse of older structures and redevelopment of blighted sites.

9, added in 2019: the Planning Department reserves the right to require additional architectural elements, including but not limited to front porches and decorative windows, and the design and materials of every building element are subject to Planning Division approval. Existing structures inside a DDD cannot be removed or altered without Planning Division approval or an approved site plan and building permit, and surface parking under buildings must be screened from public view at the Planning Department's direction. 2.
