Agriculture District — THE 25% COVERAGE IS THE LARGEST-LOT FIGURE. Note 16 slides Ag lot coverage by lot size: 60% for a lot of 1/2 to 1 acre, 50% for 1 to 2 acres, 40% for 2 to 3 acres, and 25% at 3 acres or more — the most restrictive tier is what the base row holds. LOT SIZE IN Ag IS VARIABLE (note 8): the minimum is 1/2 acre provided the Columbia County Department of Health separation distances and design standards for on-site water and sewage are met AND the average lot size across the subdivision is at least 3.5 acres. DENSITY IS CALCULATED ON NET ACREAGE (§ IV.C.2), after excluding the FEMA 100-year floodplain, State, Army Corps and Ancram Biodiversity Map wetlands and vernal pools, and land under natural or constructed water bodies including retention and detention basins — each weighted by the Table 3 multiplication factors before being applied against the 3.5-acre density. Slaughterhouses, veterinary and animal clinics, tanneries, commercial kennels, barns, stables, training arenas, greenhouses, silos and equipment sheds must meet the Table 2 side and rear setbacks from the property line of any existing adjacent residence (note 15). The front setback is measured from the right-of-way line, itself measured from the centre of the highway pavement edge to pavement edge (note 12). An attached front-loading garage or carport must sit 15 ft behind the front edge of the house, and a detached front-loading garage 35 ft from the street right-of-way (note 13). An accessory structure may stand within the rear setback provided it keeps 10 ft from the property line (note 14). For a MULTIFAMILY dwelling the minimum lot width is the figure above PLUS 2.5 ft per dwelling unit (note 11) — a per-unit increment with no field. A flag lot needs 50 ft of width; every other lot may be no more than twice as deep as it is wide.
Ancram Hamlet Residential, Ancramdale Hamlet Residential, Boston Corner Hamlet Residential — LOT SIZE MAY BE AVERAGED (note 9): lots in AH-R2, AdH-R2 and BCH-R2 may vary in size provided the AVERAGE of all lots created in a subdivision is 2 acres, so the 2 acres above is an average rather than a floor. The front yard is a RANGE: 20 ft minimum and 35 ft MAXIMUM. A new building in any hamlet district may instead match the front setback of the adjacent buildings (note 12). Density here is calculated on the TOTAL GROSS acreage of the parcel using the minimum lot size (§ IV.C.1). An attached front-loading garage or carport must sit 15 ft behind the front edge of the house, and a detached front-loading garage 35 ft from the street right-of-way (note 13). An accessory structure may stand within the rear setback provided it keeps 10 ft from the property line (note 14). For a MULTIFAMILY dwelling the minimum lot width is the figure above PLUS 2.5 ft per dwelling unit (note 11) — a per-unit increment with no field. A flag lot needs 50 ft of width; every other lot may be no more than twice as deep as it is wide.
