R Residential - The minimum lot drops to 15,000 sq ft with public water or public sewer, 10,000 sq ft with both, and 7,500 sq ft where the lot has public water, public sewer and natural gas.
R-1 Residential, R-Ag-1 Rural Agricultural - The minimum lot size is set by the percolation tests required under § 155-42, and in no event less than one acre.
- Where the lot adjoins active agricultural land, § 155-52 requires a 75 ft setback from the property line, and that setback replaces the figures shown here.
C-1 Hamlet Commercial - The minimum lot drops to 10,000 sq ft with public water or public sewer and 5,000 sq ft with both. No side yard is required in this district, and none is required even where one is provided.
C-2 Highway Commercial - The 20,000 sq ft minimum lot size is the figure for a lot without public water or sewer, and the code publishes no smaller figure where either utility is available.
HD Harbor Development - The minimum lot drops to 1.5 acres with public water and sewer. Where the lot adjoins active agricultural land, § 155-52 requires a 75 ft setback from that property line, which supersedes the yards shown.
- Height is four stories as well as 45 ft, and where the two measures disagree the lesser applies.
- A building over 35 ft requires a visual impact analysis under SEQRA because the district lies within the Coastal Boundary Zone.
