(A) Handicap accessible ramp. Where sidewalks intersect with curbs, the curb and gutter shall be removed. The curb and sidewalk shall be replaced with handicap accessible ramp to meet the Americans with Disabilities standards.
(B) Sidewalk grades and widths. All sidewalks shall be constructed in a minimum of five feet in width, except in the case of the continuation of an already constructed sidewalk which is less in width than five feet, but in no event shall a sidewalk be constructed less than four feet in width. If the sidewalk under construction is a gap between already constructed sidewalks in the same block, it shall be constructed according to the width of the wider sidewalk. The concrete shall be a minimum of four inches in thickness and shall be laid in one course in accordance with the specifications. The surface of any walk when completed shall be in conformity with the grade given by the town, and shall have a slope if 1/4 of an inch per foot toward the center of the street. All sidewalks shall be laid with the inner edge on the property line, unless otherwise directed by the town.
(C) Driveway and alley crossings. All driveway and alley crossing shall be constructed of concrete, conform to the sidewalk grade, and shall be six inches in depth of the same quality and material as specified for sidewalks.
(D) Manner for placing concrete for sidewalks. The subgrade shall be wetted before the concrete is placed thereon. The concrete shall be deposited within the forms upon the wetted subgrade to the thickness required. It shall then be leveled off and tamped sufficiently to bring the mortar to the surface, after which it shall be finished smooth and even. The edge shall be rounded with an edger having a radius of 1/4 inch. A broom shall be used for texturing and brooming shall generally be parallel to transverse joints. When the surface has received the final finish the surface shall be coated with a concrete curing compound or covered and kept wet for a period of not less than 48 hours. No concrete shall be placed on frozen subgrade. Whenever there is a danger that the temperature will reach the freezing point, sufficient straw or other suitable material shall be added to the covering material to prevent freezing of the concrete before it is thoroughly cured.
(E) Expansion joints. Preformed joint material for expansion joints shall be composed of a durable elastic compound. Expansion joints shall be placed where any sidewalk joins with any curb and gutter, where new sidewalk joins old sidewalk, and at other locations as directed by the town. Expansion joints shall be placed at intervals not to exceed 50 feet.
(F) Sidewalk transverse joints. Transverse joints shall be cut perpendicular to the sidewalk edge with a jointer having a radius of 1/4 inch, at intervals not greater than the width of the sidewalk being constructed, unless otherwise directed by the town. As an alternate method of forming transverse joints, the joints may be sawed to a depth of one inch after the concrete has hardened.
