Village of Wesley Hills, NY: zoning for new construction

Residential R-50 - A minimum effective square of a hundred and fifty feet a side must also fit inside the lot, a shape test on top of area and width. Lot width may drop to a hundred feet where the lot fronts a cul-de-sac or a street whose centre line curves at a radius of a hundred feet or less.

• Minimum lot frontage of 100 feet is a separate standard, and the Planning Board may reduce it for a lot on a cul-de-sac or a street curving at a radius of a hundred feet or less.
• An average-density lot needs at least forty thousand square feet, at least a hundred and twenty-five feet of width and ninety of frontage, with twenty-five-foot side yards and sixty for the pair.
• In an average-density subdivision of ten or more lots, a tenth of the lots may go down to thirty-five thousand square feet.
• Building coverage is the footprint alone; the impervious surface ratio adds drives, terraces and every other hard surface, and a separate ratio caps front-yard impervious surface at 0.15 in R-50.
• The height shown is the maximum building height; a larger maximum exposed building height of forty feet is allowed in the residential districts, measured where the ground falls away.
• Not more than a quarter of land under water, in a hundred-year floodplain, in a utility or other easement or right-of-way, or with unexcavated slopes over 25% may count toward the minimum lot area.

Residential R-35 - A minimum effective square of a hundred and twenty-five feet a side must also fit inside the lot, a shape test on top of area and width. Lot width may drop to seventy-five feet on a cul-de-sac or tightly curved street.

• Minimum lot frontage of 100 feet is a separate standard, and the Planning Board may reduce it for a lot on a cul-de-sac or a street curving at a radius of a hundred feet or less.
• An average-density subdivision lot needs at least thirty thousand square feet and at least a hundred and ten feet of width.
• In an average-density subdivision of ten or more lots, a tenth of the lots may go down to twenty-five thousand square feet.
• Building coverage is the footprint alone; the impervious surface ratio adds drives, terraces and every other hard surface, and a separate ratio caps front-yard impervious surface at 0.20 in R-35.
• The height shown is the maximum building height; a larger maximum exposed building height of forty feet is allowed in the residential districts, measured where the ground falls away.
• Not more than a quarter of land under water, in a hundred-year floodplain, in a utility or other easement or right-of-way, or with unexcavated slopes over 25% may count toward the minimum lot area.

Residential R-20 - A minimum effective square of 90 ft a side must fit inside the lot, on top of the area and width. Where the lot carries pavement for a common driveway, the impervious ratio rises from 0.25 to 0.45.

• Minimum lot frontage of 90 ft is a separate standard, and the Planning Board may reduce it for a lot on a cul-de-sac or a street curving at a radius of a hundred feet or less.
• Building coverage is the footprint alone; the impervious surface ratio counts drives, terraces and every other hard surface with it.
• A separate ratio caps impervious surface in the front yard alone, at 0.20 in this district.
• The height shown is the maximum building height; a larger maximum exposed building height of 40 ft is allowed in the residential districts, measured where the ground falls away.
• Not more than a quarter of land under water, in a hundred-year floodplain, in a utility or other easement or right-of-way, or with unexcavated slopes over 25% may count toward the minimum lot area.

Residential R-15 - A minimum effective square of 90 ft a side must fit inside the lot, which on a 62.5 ft width forces a deep parcel. The Planning Board may reduce the 62.5 ft frontage to 50 ft on a cul-de-sac or tightly curved street.

• There is no storey limit here and no front-yard impervious ratio.
• Where the lot carries pavement for a common driveway, the impervious ratio rises from 0.25 to 0.45.
• Building coverage is the footprint alone; the impervious surface ratio counts drives, terraces and every other hard surface with it.
• The height shown is the maximum building height; a larger maximum exposed building height of 40 ft is allowed in the residential districts, measured where the ground falls away.
• Not more than a quarter of land under water, in a hundred-year floodplain, in a utility or other easement or right-of-way, or with unexcavated slopes over 25% may count toward the minimum lot area.

Neighborhood Shopping - A minimum effective square of 150 ft a side must fit inside the lot, a shape test on top of the area and width.

• Minimum lot frontage of 150 ft is a separate standard, and the Planning Board may reduce it for a lot on a cul-de-sac or a street curving at a radius of a hundred feet or less.
• Building coverage is the footprint alone; the 80% impervious surface ratio counts drives, terraces and every other hard surface with it.
