The following construction standards and improvements shall be considered the minimum standards necessary to protect the health, safety, welfare, and convenience of the residents and public as well as needed to meet local, county, regional, state and national goals and objectives. It is recognized, however, that in peculiar situations, all of the improvements listed below may not be appropriate, or needed, or sufficient.
The pavement area of all streets shall be constructed of grade "A" or "B" road gravel, having a minimum depth of eight inches after compaction, and be uniformly graded and crowned to the established grade and cross section. The crown shall not be less than 3/8 inch per foot, based on the 1/2 width of the pavement, i.e., distance from center line to curbline. The gravel pavement shall be surface treated with a single course, hot-mixed bituminous concrete (type FABC-1) at least two inches thick and weighing at least 220 pounds per square yard. All materials and methods of construction shall comply with the applicable requirements therefor as provided in the standard form of New Jersey State Highway Department Specification. All traffic lanes, both moving and parking, shall be striped in accordance with the Manual on Uniform Traffic Control Devices, as amended. (US Department of Transportation, Federal Highway Administration, 1971.)
Continuous permanent curbs of concrete 4,500 p.s.i., shall be constructed along each pavement edge. Curbs shall be at least 16 inches high by six inches thick at the top and eight inches thick at the base with the slope on the pavement face and shall extend six inches above the pavement wearing surface. Depressions in the curb to within two inches of the wearing surface may be provided for driveways. Curbs shall be constructed with expansion joints a minimum of 1/2 inch in thickness, located a maximum distance of every 25 feet along the curb. The expansion joints shall be filled with a piece of cellular compression material cut to fit the curb section. Curbs shall have minimum fifteen-foot radii at intersections. In place of the foregoing described type of curb construction, a roll-type curb may be installed, provided the City Engineer first approves the specifications for same and the location of same.
A sidewalk shall be constructed on either side of the street pavement within the street right-of- way and shall be constructed at least one foot from each right-of-way line and wherever possible four feet from the curbline. The exact location shall be agreed upon by the subdivider and City Engineer before the plan of improvements is completed. All sidewalks shall be of concrete, 4,000 p.s.i., and shall not be less than four feet in width by four inches thick, except where wider sidewalks may be required by the Planning Board in high density residential or business developments. Sidewalks shall follow required street profiles and right-of- way cross sections. Expansion joints at least 1/2 inch thick shall be provided at a minimum distance of every 20 feet along the sidewalk. The expansion joint shall be filled with a piece of cellular compression material cut to fit the sidewalk section. There shall be a minimum lateral pitch of 1/4 inch to one foot, from the curbline to the property side of the sidewalk, sloping to street.
Water mains shall be of a material and a minimum diameter of eight inches as approved by the Superintendent of the Water/Sewer Utility for permanent installation in the street concerned. Installation of water mains and connections to the existing system shall be in accordance with the current specifications of the American Water Works Association. The necessary valves and hydrants to form a complete system in the area under development shall be provided and installed in accordance with the current specification of the American Water Works Association.
Sanitary sewers shall be constructed of a material and of a diameter and at the line and grade approved by the Superintendent of the Water/Sewer Utility. All lateral connections to the sewer shall be made with an approved "saddlecasting" of appropriate size bolted to the sewer pipe. Sanitary sewer manholes shall be constructed of brick or concrete block, with approved head casting and complete pipe invert. Such manholes shall be located at the end of each sewer line, at intersections and at all changes of grade or alignment. Distances between manholes shall not exceed 400 feet.
Culverts, storm sewers, storm drains, storm sewer manholes and catch basins adequate to accommodate all surface or subsurface water reaching the development or accumulating thereon shall be as shown on the plan and profile of stormwater facilities accompanying the final plat. The line, grade and location of these storm drainage facilities shall also be as approved by the City Engineer. No storm sewers, culverts, or storm drains shall be a diameter less than 12 inches. All manholes shall be constructed of brick or concrete block of a type approved by the City Engineer. All catch basins shall have curb-type head and grate castings.
There shall be one metal street name sign post of galvanized steel installed at each street intersection, so located as to be visible for both pedestrian and vehicular traffic. The post shall be 2 1/2 inches in diameter and three feet in the ground. The type of name sign shall conform with existing signs and be approved by the City Engineer. All name signs shall have a clearance of not less than eight feet above the ground. There shall be an individual name sign identifying each intersecting street.
Any subdivision located adjacent to tidal waters or having canals or lagoons in or adjacent to it shall be provided with adequate bulkheads or other appropriate shore protection measures at all points of surface water contact, constructed according to standards and in location approved by the City Engineer.
Where lagoons are constructed they shall be not less than 140 feet wide from bulkhead to bulkhead and no piling, dock, catwalk or other structure shall extend or be located more than 30 feet beyond any bulkhead, providing a clear, unoccupied boat maneuvering area at least 80 feet wide. In order to minimize water stagnation and trash accumulation, dead-end lagoons shall not exceed 750 feet in length. Lagoons may be constructed to a greater length only when both ends open into natural water bodies or when the closed end is joined to open water or an adjacent lagoon by a culvert of a size and design approved by the City Engineer. All lagoons shall be dredged to provide a minimum water depth at mean low tide of four feet adjacent to the bulkhead and six feet along the lagoon center line.
Except in subdivisions which the Planning Board shall determine to have an adequate number of existing shade trees, the subdivider shall plant street trees, which shall be placed on the building side of the sidewalk or sidewalk area. Street trees shall be a minimum of 50 feet and a maximum of 60 feet apart and be not less than two inches in diameter at time of planting. The type of street trees to be used shall be determined by the Cape May City Shade Tree Commission.
