|---|---|---|---|---|
| Village Center | 0.0918 ac | 0 / 0 / 10 ft | 40 ft | Special permit |

Village Center — The front yard is a RANGE, not a minimum: 0 ft minimum and 5 ft MAXIMUM. A building may not be set further back than the maximum, which is a build-to line. Village Center is the one district with a MAXIMUM SIDE yard as well as a maximum front yard: a building may not sit more than 25 ft from the side lot line. Inside the Special Sensitivity Overlay the Village Center takes a different column entirely — a 10 ft minimum and 25 ft maximum front yard, a 10 ft minimum side yard and no side maximum — while the lot area, frontage, width, height and coverage stay the same. Minimum lot frontage is 40 ft, published separately from the 40 ft lot width. Where two properties are separated by a district boundary, the LARGER of the two required yards applies to both, whichever type of yard it is (§ 120-10). Eaves and similar building features may encroach up to 3 ft into a front yard. A sight triangle must be kept clear 25 ft in both directions from a street corner and 10 ft from a driveway curb cut (§§ 120-11, 120-12).
Residential — The front yard is a RANGE, not a minimum: 10 ft minimum and 25 ft MAXIMUM. A building may not be set further back than the maximum, which is a build-to line. The Planning Board may instead let a structure be built anywhere within the setbacks of the two adjacent structures on the same side of the street, measured from the street; a corner lot may average the adjacent lot on each side. Parcels in the Bulkeley Schoolhouse Overlay District take the dimensional standards at § 120-39.1D instead of these. Minimum lot frontage is 60 ft, published separately from the 60 ft lot width. Where two properties are separated by a district boundary, the LARGER of the two required yards applies to both, whichever type of yard it is (§ 120-10). Eaves and similar building features may encroach up to 3 ft into a front yard. A sight triangle must be kept clear 25 ft in both directions from a street corner and 10 ft from a driveway curb cut (§§ 120-11, 120-12).
Gateway Business — The front yard is a RANGE, not a minimum: 20 ft minimum and 40 ft MAXIMUM. A building may not be set further back than the maximum, which is a build-to line. Minimum lot frontage is 75 ft, published separately from the 75 ft lot width. Where two properties are separated by a district boundary, the LARGER of the two required yards applies to both, whichever type of yard it is (§ 120-10). Eaves and similar building features may encroach up to 3 ft into a front yard. A sight triangle must be kept clear 25 ft in both directions from a street corner and 10 ft from a driveway curb cut (§§ 120-11, 120-12).
Medical and Professional — The front yard is a RANGE, not a minimum: 10 ft minimum and 25 ft MAXIMUM. A building may not be set further back than the maximum, which is a build-to line. Minimum lot frontage is 70 ft, published separately from the 70 ft lot width. Where two properties are separated by a district boundary, the LARGER of the two required yards applies to both, whichever type of yard it is (§ 120-10). Eaves and similar building features may encroach up to 3 ft into a front yard. A sight triangle must be kept clear 25 ft in both directions from a street corner and 10 ft from a driveway curb cut (§§ 120-11, 120-12).
Fairgrounds — The Fairgrounds District is excluded from the Dimensional Table; its standards are in § 120-38G. The 25 ft front figure is the ROUTE 9 setback, and it rises to 75 ft where the parcel is adjacent to a residential district. Minimum lot frontage and minimum lot width are both 200 ft. Beside the 20% building coverage there is a 40% MAXIMUM IMPERVIOUS coverage, which is the limit parking and drives count against. Every building and zoning permit needs site plan approval under Article XI, and the improvements and lot lines shown on the As-Built Survey and Fairgrounds District Map are deemed conforming. A buffer zone on that map allows only temporary parking, roads and driveways, and requires new utility lines to be placed underground. Where two properties are separated by a district boundary, the LARGER of the two required yards applies to both, whichever type of yard it is (§ 120-10).
