§ 28-11.6

Sidewalks and Driveways.

[Added 4-20-2021 by Ord. No. 03-2021]
a. 
Sidewalks shall have minimum width of four feet and four inches thickness except at driveways and aprons where the sidewalks shall be six inches in thickness. The sidewalk at driveways and aprons shall be reinforced with six-inch #6 gauge welded mesh reinforcement or equivalent placed four inches below the finished sidewalk surface. Sidewalks shall be constructed at the locations and to the prescribed lines and grades as approved on the preliminary plat, but sidewalks shall be constructed after the adjacent curb has first been installed. The subgrade shall be smooth and even and shall be compacted by rolling and three-quarter-inch broken stone shall be spread to a depth of not less than four inches and compacted where directed by Borough Engineer. Concrete for sidewalks shall be State Mix Class "B" air entrained 4,000 PSI concrete, and shall be manufactured in accordance with New Jersey State Highway Department's Standard Specifications for Road and Bridge Construction-1961 and addenda, and shall originate in a ready-mixed plant that has been certified and approved by the National Ready-Mixed Concrete Association.
b. 
Concrete shall be placed to a thickness of four inches, tamped, screened, and finished to true grade. The finish shall be with a wood float, followed by brushing with a set of soft-haired brushes to a neat workmanlike surface. Expansion joints one-half-inch wide shall be provided at intervals of 16 feet and filled with preformed bituminous expansion joint filler. Surface grooves shall be cut perpendicular to the line of the sidewalk at intervals of eight feet and full cuts at 16-foot intervals. Exposed edges shall be neatly rounded to a radius of one-half inch.
c. 
The sidewalks will be located within the street right-of-way one foot from the street right-of-way line as measured toward the centerline of the street. At street intersections the sidewalks shall be placed so that pedestrian traffic can cross the street by stepping directly from the sidewalk to street. The minimum width of the additional sidewalk required at street intersection to effect this, shall be four feet.
d. 
Driveways shall have a minimum width of 12 feet. The subgrade shall be smooth and even and shall be compacted by rolling with a five-ton to eight-ton roller after which bank run gravel shall be spread to a depth of not less than three inches and compacted with a five-ton to eight-ton roller. There shall be a four-inch bituminous stabilized base course with a one-and-one-half-inch type SM or FABC surface course also compacted with a five-ton to eight-ton roller. If concrete driveways are constructed, they will be 12 feet wide and shall be six inches throughout. The entire length of the driveway shall be reinforced (or equivalent) placed four inches below the finished driveway surface. All driveways will be of adequate length and width to provide off-street parking for a minimum of two cars and shall slope a minimum of one-fourth inch per foot toward the street curb.
