[1]
Editor's Note: The Tables of Area Regulations and Height and Bulk Regulations are included as attachments to this chapter.
The Table of Area Regulations included as an attachment to this Bylaw, together with the notes therein, are part of this Bylaw.
A. 
Except for multifamily residential developments, planned business and industrial developments, public housing for the elderly, agricultural use, community facilities and public utilities (see Article 14), only one principal structure shall be permitted on one lot.
B. 
For purposes of determining setback requirements, both yards of a corner lot that front on a street shall be considered front yards on the street on which they are located.
C. 
A legal service driveway shall have a minimum width of 12 feet and a maximum width of 24 feet.
D. 
For purposes of determining setback requirements, both yards of a through lot that front on a street shall be considered front yards on the street on which they are located.

Frontage.
(1) 
Frontage shall be measured at the street line. On corner and through lots, frontage shall be measured on one street only.
(2) 
Frontage for municipal water wells and water storage standpipes shall not be required.

Building within the following districts will be subject to the respective Zoning Bylaw Section: Open Space Residential, Article 7; Floodplain District, Article 10; Watershed Protection District, Article 11; and Aquifer Protection District, Article 16.
G. 
Only the following projections into required yards or other required open spaces are permitted:
(1) 
A balcony or bay window limited in total length to 1/2 the length of the building shall project not more than two feet.
(2) 
Open terrace, steps or stoop under four feet in height shall project not more than 1/2 of the required yard setback.
(3) 
Steps or stoop over four feet in height, window sill, belt course, chimney, roof eave, fire escape, fire tower, storm enclosure or similar architectural features shall not project more than two feet into the required yard setback area.
H. 
In B and BI Districts, all uses shall be conducted within a completely enclosed building, except: dispensing of food, beverages or goods at a drive-in or stand; dispensing of gas, water or lubricants at a garage or gasoline service station; vegetation held for sale in a horticulture or floriculture business; permitted parking or loading; and permitted exterior signs.
I. 
Screening and buffers shall be required in the Industrial-Extensive (IE) District. There shall be a landscaped buffer strip along each boundary which adjoins a residential use or district. This strip shall be at least 150 feet in width and shall be portioned as follows:
(1) 
The portion of such buffer strip within 100 feet of the district boundary line shall be used only for, and maintained as, a planting area for lawns, trees, shrubs, or other landscape materials to provide a visual barrier between districts.
(2) 
The remaining 50 feet of space may be used for off-street parking or other permitted open uses, and shall not contain any permanent structure.
J. 
In a Business District, a Business-Industrial District or a lot in an RU District on which a multifamily dwelling is placed, there shall be a landscaped buffer strip along each boundary which adjoins a residential lot. The strip shall be at least 25 feet in width and shall contain a screen of plantings in the strip not less than five feet in width and six feet in height at the time of the occupancy of any lot. Individual bushes or trees shall be planted not more than six feet on centers, and shall thereafter be maintained by the owner or occupants so as to maintain a dense screen year round. All of the plantings shall be evergreen. No building, structure, driveway, or other artificial improvements, except such fencing as the Planning Board may require, shall be placed within this buffer strip. A waiver of the required plant spacing may be granted if, in the opinion of the Planning Board based on evidence submitted by applicant, the wider spacing allows the proposed plantings to thrive and fully mature while providing a long-term healthier vegetative screen. The relief of plant spacing will allow for plantings to be concentrated in areas where a fuller vegetative screen is required or desired. A waiver on the plant spacing does not allow for a reduction in the overall plant quantity.
[Amended 4-30-2018 ATM by Art. 40]
K. 
In any R District, permitted accessory buildings shall conform to the following provisions: They shall be not less than 60 feet from any street lot line, except for a garage on a corner lot, which shall be set back at least the same distance as the front yard setback for the adjacent lot; and they shall be set back from side and rear lot lines at least the distance specified in the Table of Area Regulations, provided that one accessory structure that will not exceed 15 feet by 10 feet, and not exceeding 12 feet in height, shall be allowed to be located in the rear yard with a setback to the rear lot line of no less than 20 feet and side lot line of no less than 12 feet.
