Notes: | ||
|---|---|---|
A. | See section 402 for dimensional requirements in a cluster or multi-family development. | |
B. | Motels/hotels, where allowed, shall have a minimum lot area of 25,000 square feet and shall be constructed at a density of not more than one (1) unit per one thousand (1,000) square feet of lot area and shall conform to the minimum lot size in the table above. | |
C. | Except for properties to which Section 404 applies, two-family dwellings, where allowed, require twice (2 times) the normal minimum lot size of the district. | |
D. | The following are specifically excluded from these regulations: | |
1. | Fences, walls, poles, posts, paving and other customary yard accessories, ornaments and furniture, ramps, landings and similar structures needed for handicapped access. | |
2. | Cornices, window sills, belt courses and other ornamental features may project not more than eighteen (18) inches; bay/bow windows, greenhouse windows and eaves may project not more than twenty-four (24) inches, and chimneys may project not more than thirty-two (32) inches into any required yard. | |
3. | Any stairway and associated landing may project into a required front yard if it is less than thirty (30) inches in height. | |
E. | Side and rear yard setbacks for accessory buildings containing one hundred fifty (150) square feet or less and single story, shall be six (6) feet in all districts, but in no case shall said accessory buildings be built closer than twelve (12) feet to any other building on an adjacent parcel. | |
F. | Corner lots shall have frontage on one street of at least the minimum required in the Table of Dimensional Requirements (203.5) and frontage of at least one hundred (100) feet on any other abutting street. | |
G. | See section 203.2 for reductions to minimum frontage. | |
H. | Lot width shall at least meet the minimum frontage for a depth of one hundred (100) feet. | |
I. | No building need be set back more than thirty percent (30%) of the depth of the lot nor more than the average of the setbacks of the buildings on the lots next thereto on either side, but no closer than 20' in the B1, B2, B3, HMOD1 and HMOD2 zoning districts to provide for vegetated buffers. A vacant lot or a lot occupied by a building set back more than the required front yard setback being counted as though occupied by a building at the setback line. | |
J. | Except for lots adjoining and southerly of Route 6 along Station Avenue, seventy-five (75) feet. | |
K. | Except where the district abuts Old Town House Road, seventy (70) feet; or except where an B3 District adjoins a Residential District, no business or building shall be within fifty (50) feet of the district boundary. | |
L. | The developed footprint of impervious surfaces (structures, pavement, etc.) including any unpaved parking areas, shall not exceed 70% of the total square footage of any lot. Pervious paving shall be counted as impervious in lot impervious coverage calculations. | |
M. | (Deleted). | |
N. | One hundred percent (100%) of the minimum lot size required must be upland (i.e., not a bank, beach, bog, dune, marsh, swamp or wet meadow under M.G.L. ch. 131, sec. 40). | |
O. | (Not used). | |
P. | 15% Maximum impervious lot surface coverage, or 2500 square feet of any lot, whichever is greater, unless artificial recharge for excess runoff is provided, as noted in 310 CMR 22.21 (2)(b)8. In no case will the maximum building coverage exceed 35% of the total lot area nor total impervious lot coverage exceed 70% of the total lot area when an approved artificial recharge system for stormwater runoff has been provided. Pervious paving shall be counted as impervious in lot impervious coverage calculations. | |
Q. | The height provisions of 203.4 may be extended to no more than 85 feet, or a maximum of 6 stories, for approved medical and medical related uses in the MOD only on the following lots: Assessor's Map 36, Lot 1 and Assessor's Map 28, Lots 51, 52, 53, 54, and 55. | |
R. | The dimensional requirements set forth in section 203.5 for the MOD may be altered by special permit from the Board of Appeals in accordance with section 103.2 on only the following lots: Assessor's map 36, Lot 1 and Assessor's Map 28, Lots 51, 52, 53, 54, and 55. | |

T. | (Not Used) | |
U. | Dwellings are also subject to the required 100 foot setback from a cranberry bog outlined in Bylaw section 405.2. | |
V. | The lot shape factor shall be obtained by dividing the square of the lot perimeter (P), measured in feet, by the area of the lot (A), measured in square feet (i.e.: P2 ÷ A). Lots in existence before October 05, 2005 that are not in compliance with this provision shall not be deemed nonconforming, by virtue of shape. Lots may have a shape factor larger than 22, provided that the portion of the lot intended for building meets the minimum lot area and upland requirements for the zone in which it is located and that such building area has a shape factor not exceeding 22. | |
W. | Refer to Bylaw Sections 415.5.14 and 415.5.15 for additional setback requirements to residential zoning districts and certain types of structures or uses. | |
X. | Corner lots are considered to have two front yard setbacks and two side yard setbacks. The front yard setback for corner lots may be reduced to 25' to accommodate parking in the rear or side of the building. If the corner lot has a curved radius along the frontage on a public way, the front yard setback may be reduced to 20' at the corner only. Refer to illustrative Figure below. | |

Y. | Bus Shelters of 120 square feet (sf) and less may be located within the front yard setback if approved by the Site Plan Review Team and located so as not to impede sight lines and traffic visibility, and must be entirely located on the subject property. | |
