10. | The rear yard setback requirements may be waived for piers where a pier is constructed in a nonresidential district or where a pier is allowed by special permit in a residential district. | ||
11. | Provided, however, that the Planning Board may grant a special permit to allow a minimum lot frontage on a common private way shown on an enclosed residential compound plan pursuant to the Subdivision Rules and Regulations of the Planning Board.[1] In issuing any special permit for reduced frontage in a residential compound, the Planning Board shall require the applicant to demonstrate that, through easements, restrictive covenants or other appropriate legal devices, the maintenance, repair, snow removal and liability for the common driveway within the residential compound shall remain perpetually the responsibility of the private parties, or their successors-in-interest, and that any breach of this condition shall be deemed noncompliant with the terms of any special permit issued hereunder. Any subsequent change to the roadway surface after the construction of a residential compound shall require a modification of the endorsed plan pursuant to MGL c. 41, § 81W and this special permit. | ||
12. | Provided, however, that the Planning Board may grant a special permit to allow a lesser setback. In issuing any special permit for reduced setbacks, the Planning Board shall require the applicant to provide parking, curbing, street trees, or other plantings, and pedestrian access in a manner acceptable to the Planning Board. Through easements, restrictive covenants or other appropriate legal devices, the maintenance, repair, snow removal and liability for the sidewalk and street trees or other plantings on the property of the business shall remain the responsibility of the owner of said property. | ||
13. | Provided, however, that the Planning Board may grant a special permit to allow a use, other than a one- or two-family dwelling, as allowed by the Table of Principal Use Regulations on parcels equal to or greater than 5,000 square feet and with a minimum of 50 feet of frontage, provided that the project is otherwise in harmony with the provision of the Zoning Bylaw and the lot was in compliance with the applicable zoning at the time the lot was created or shown on a plan endorsed by the Planning Board. | ||
Dimesional Table Explanations: |
A.
The height of a building abutting a street shall be measured from the average finished grade on the street side(s) and if not abutting a street from the mean ground level along its front to the highest point of the exterior in the case of a flat roof or to the ridge in the case of a pitched roof.
B.
Front, side and rear yard setbacks shall be measured from the nearest point of any structure or dwelling to each front, side or rear lot line. Uncovered steps, ramps, and bulkheads or the construction of walls or fences not exceeding six feet in height shall not be considered part of the structure for the purposes of measuring setbacks. A chimney and all types of decks shall be considered part of a structure.
C.
A detached accessory building shall conform to the minimum setback from any boundary. Any building attached to a dwelling will be considered as part of the dwelling.
D.
All buildings on lots abutting Route 6 (Mill Street and Wareham Street) shall be set back at least 50 feet from said right-of-way. No building, except on lots on Route 6, need to be set back more than the average of the setback of the building next thereto (within 250 feet) on either side. A vacant lot, or lot occupied by a building set back more than the minimum setback requirements, shall be counted as though occupied by a building set back at this requirement.
E.
Frontage for the width of a lot shall be measured continuously along one street line between side lot lines, provided that the shape of the lot is capable of containing a rectangle with a width of at least 75 feet at the front of the property line and with sufficient length that the area of the rectangle contains no less than 50% of the minimum lot size requirement.
F.
Each lot shall have a width of not less than 80% of the required frontage at all points between the sideline of the right-of-way along which the frontage of the lot is measured and the nearest point on the front wall of the dwelling upon such lot. Such width shall be measured along lines which are parallel to such sideline. (See following figure.)
G.
The thinnest cross section of a lot must be greater than 70 feet as determined from the length of a line segment running parallel to the front lot line. Rear lot access is exempt from this requirement.
H.
On a corner lot, the frontage requirement shall be measured to the midpoint of the curve forming the intersecting streets. On a corner lot, an accessory use, including a visual screen, must comply with the setback requirements relating to both streets.
I.
On corner lots, an accessory structure, including but not limited to visual screening, shall comply with the requirements relating to front and side setbacks for the district which it is located. No visual screening such as fences, shrubs, or trees shall block the sight triangle of oncoming traffic as to cause a safety hazard.
(1)
A fence, hedge, wall or other enclosure may be maintained on a corner lot, provided that no structure or vegetation shall be over 3.5 feet in height from the road surface within the sight triangle.
(2)
The "sight triangle" is defined as the area within a triangle formed by two lines measured along the center of the nearest lane or the traveled way of intersecting streets from the point of intersection for a distance of 25 feet and a third line connecting the points of the two legs. The height restrictions shall designate the distance above each point in the plane of the sight triangle.
J.
The limitations of height in feet shall not apply to chimneys, ventilators, skylights, water tanks, bulkheads, and other accessory features usually carried above roofs, nor domes, towers, or spires of churches or other buildings, provided such features are in no way used for living purposes, and further provided that no structural feature of any building shall exceed a height of 65 feet from the ground except by special permit from the Board of Appeals.
K.
A detached accessory building shall conform to the minimum setback requirements of the lot on which it is located except where a dwelling exists on lots which are less than minimum requirements, in which case the Board of Appeals may by special permit authorize such reductions of setback requirements as may be reasonable with respect to the size and shape of the lot and not hazardous or detrimental to the neighborhood and the adjacent lots.
