(Ad ourned Session of the 1985 Annual Town Meeting _ April 16, 1956} 4— Article 45. (Motion as attached to the Planning Board Report and as amended (Cont.) and as adopted: (Cont.) a. The lower elevation shall be: the natural grade of the land at the point of measurement prior to disturbance for construction. The elevation of the natural grade prior to disturbance for construction shall be certified by a registered land surveyor, or may be such elevation as the Building Commissioner may deter - mine from Town maps or records. An average natural grade may be used, which shall be determined by computing the average of the elevations of the natural grade of the four extreme corners of the building, or, in the case of a non - rectangular building, of such equivalent locations as the Building Commissioner may determine. In a case where the lower elevation, thus determined, is lower than the average of the elevations of adopted) the natural grades of the four extreme corners of the lot, the average of the elevations of the corners of the lot may be used. In a case where the finished grade is lower than the natural grade, the finished grade shall be the lower elevation. b. The upper elevation shall be: 1) in the case of a flat roof, the top of the highest roof beams; or 2) in.the case of a pitched, gable, hip, gambrel, or mansard roof, the horizontal plane that passes through the ceiling of the top story. Where the top story is not finished with a horizontal ceiling, the elevation seven feet above the floor of the top story shall be considered equivalent to the ceiling. 7.5.2 STRUCTURES OTHER THAN BUILDINGS: When located on the ground, the maximum height of structures, other than buildings, shall be the highest point on the structure and shall not exceed the maximum height for buildings as set forth in Table 2. Structures other than buildings, such as antennas, recreational apparatus, fences and the like may be located in required front, rear or side yard provided the height of the structure is not greater than its horizontal distance from the lot line, except that a fence or wall not greater than six feet in height may be located on, or closer to a lot line than six feet. Structures erected on a building and not used for human occupancy, such as chimneys, heating - ventilating or air conditioning equipment, solar or photovoltaic panels, elevator housings, antennas, skylights, cupolas, spires and the like may exceed the maximum height of a building provided no part of the structure is more than 20 feet higher than the upper elevation of the building and the total horizontal coverage of such structures on the building does not exceed 25 percent. The Board of Appeals may grant a special permit for structures, but not buildings, to exceed the maximum height, or the percentage of horizontal coverage of structures erected on a building, specified above provided it makes a determination that the structure is compatible with the scale of the neighborhood and does not intrude on the solar access of any adjoining lot. 7.5.3 AVERAGE HEIGHT OF BUILDING: Where a building has different elements, some higher than others, some elements may be higher than the maximum height if other elements are lower than the maximum height, provided the average height of the entire building does not exceed the permitted maximum height. The average height shall be computed by determining the height of the individual elements and computing an average proportionate to the building coverage of the various elements. Where a building is on .a sloping site or has some stories that do not extend for the full building coverage, the height of the several elements of the building may be calculated separately provided that neither the maximum height or the number of stories in any one element exceeds that permitted by Table 2.
