Editor's Note: Table V-1 is included at the end of this chapter.
Shoulders, where required, shall be constructed, unless otherwise specified, of shoulder stone, as directed, and rolled with a three-wheel power roller, weighing not less than 10 tons. At the discretion of the Township Engineer, a roller weighing not less than four tons may be used for this purpose. When completed, the shoulders shall be to the required cross section.
Excavation and embankment shall consist of accurately grading to approved line and grade the full width of the right-of-way in conformity with the specifications. Grading shall include clearing and grubbing, removal of structures and obstructions, as directed, excavating, forming embankments, shaping and sloping, compacting and all other work that may be necessary to bring the roadway and its appurtenances to the required grade, alignment and cross sections. Grading of all intersections (roadways, driveways and approaches) and adjacent property to the limit of the slope lines is included in this section.
A. 
Grubbing and clearing. The developer shall remove and dispose of all trees, stumps, roots, brush, weeds, etc., and fill the holes with suitable material and thoroughly compact the same. Culverts shall be cleaned and cleared of obstructions where directed or specified. All branches of trees projecting over the curbline which hang closer than 14 feet to the surface of the roadway shall be removed.
B. 
Roadway excavation. Roadway excavation shall include the removal and satisfactory disposal of all materials taken from within the limits of the work area that are necessary for the construction and preparation of the roadbed, embankment, subgrade, shoulders, slopes, side ditches, drainage structures, trenches, waterways, intersections, approaches and private entrances, as indicated and directed. All suitable materials removed from the excavations shall be used as far as practicable in the formation of the embankment, subgrade and shoulders and at such other places as directed. Ditches and waterways shall be excavated to the depth and width shown on plans or as may be indicated and directed. During the construction of the roadway, the roadbed shall be maintained in such condition that it will be well-drained.
C. 
Embankment. Embankments shall be formed of suitable material placed in successive layers of not more than 12 inches in depth for the full width of the cross section and shall be compacted by approved mechanical equipment and by distributing the necessary hauling uniformly over each succeeding layer. Stumps, trees, rubbish and/or other unsuitable material or substance shall not be placed in the embankments.
D. 
Borrow excavation. When the amount of the embankment exceeds the amount of the excavation within the limits of the work, sufficient suitable material shall be obtained by the developer from borrow pits located beyond the limits of the work. This material shall be known as "borrow" and shall be of a quality satisfactory for the purpose for which it is required and it shall be approved by the Township Engineer. Borrow will include the furnishings, removal, placing and satisfactory compaction of the additional material necessary to complete the embankments, subgrade and shoulders.
A. 
Street names. No street shall have a name which will duplicate or so nearly duplicate in spelling or phonetic sound as to be confused with the names of existing streets. The continuation of an existing street shall have the same name. The names of new streets must be approved by the Township Committee.
B. 
Street signs. Street signs shall be metal on metal posts of the type, design and standard previously installed elsewhere in the township and approved by the Township Engineer. The location of the street signs shall be determined by the Board but there shall be at least two street signs furnished at each intersection. All signs shall be installed free of visual obstruction.
Concrete curbs and gutters shall be installed when the center-line grade of the road exceeds 4% within the development and at intersections with township roads, county roads and state highways, unless recommended otherwise by the Township Engineer. The standard curb section to be used shall be not more than 10 feet in length measuring six inches in width at the top and eight inches in width at the base, 18 inches deep, of Class B white concrete and shall be set in accordance with approved lines and grades. Radial curbs shall be formed in an arc segment, in a smooth curve. Chord segments are prohibited. Where integral concrete curb and gutter are used, the bituminous cartway is to be reduced in width by four feet with the two-foot concrete gutter on each side making up the four-foot reduction.
[Amended 4-27-1995 by Ord. No. 95-5]
Shade trees shall be planted where required. All shade trees shall have a minimum caliper of 2 1/2 inches measured three feet above the ground and be of a species approved by the Board. Trees shall be planted 50 feet apart and 10 feet from the curbline. Stripping trees from a lot or filling around trees on a lot shall not be permitted unless it can be shown that grading or construction requirements necessitate removal of trees, in which case those lots shall be replanted with trees to reestablish the tone of the area and to conform with adjacent lots. Special attention shall be directed toward the preservation of major trees by professional means.
Monuments to be the size and shape required by the Map Filing Law, as amended,[1] shall be placed in accordance with said statute and indicated on the final plat. The top of the monument shall be flush with the final grade. All lot corners shall be marked with a metal alloy pin of permanent character.

Editor's Note: See N.J.S.A. 46:23-9.9 et seq.
All water main, culvert, storm sewer and sanitary sewer installations shall be properly connected with an approved system and shall be adequate to handle all present and probable future development. The township may require easements or rights-of-way of sufficient width along watercourses to permit truck and feeder sanitary sewers, storm sewers and other utility services.
[Amended 4-27-1995 by Ord. No. 95-5]
Sidewalks shall be required. The Approving Board may grant a waiver of this requirement if the developer can establish by competent proof that, due to probable volume of pedestrian traffic, the development's location in relation to other population areas, and the general type and character of the development intended, no sidewalks should be required. Where required, sidewalks shall be at least five feet wide and located as approved by the Board. Sidewalks shall be concrete and shall be constructed in accordance with the specifications of the New Jersey Department of Transportation, Specification for Road and Bridge Construction, most current edition.
A. 
Underground service connections. All public services shall be connected to an approved public utilities system where one exists. For all major subdivisions, the developer shall arrange with the servicing utility for the underground installation of the utilities. Distribution supply lines and service connections shall be in accordance with the provisions of the applicable standard terms and conditions incorporated as a part of its tariff as the same are then on file with the State of New Jersey Board of Public Utility Commissioners, and the developer shall provide the township with three copies of a final plat showing the installed location of these utilities. For a minor subdivision, service connections shall be made underground where the supply lines that serve the lands being subdivided are underground. For major subdivisions, the developer shall submit to the Board, prior to the granting of final approval, a written instrument for each serving utility, which shall evidence full compliance or intended full compliance with the provisions of this section, provided that lots which, in such subdivision(s), abut existing streets where overhead electric or telephone distribution supply lines and service connections have heretofore been installed may be supplied with electric and telephone service from those overhead lines, but the service connections from the utilities overhead lines shall be installed underground. In the case of existing overhead utilities, should a road widening or an extension of service or other such condition occur as a result of the subdivision and necessitate the replacement or relocation of such utilities, such replacement or relocation shall be underground.
B. 
Live screening. An installation under this section to be performed by a servicing utility shall be exempt from the provisions of requiring performance guaranties and inspection and certification by the Township Engineer. Where natural foliage is not sufficient to provide year-round screening of any utility apparatus appearing above the surface of the ground, other than utility poles, the applicant shall provide sufficient live screening to conceal such apparatus year round. On any lot where, by reason of soil conditions, rock formations, wooded area or other special condition of land, the applicant deems it a hardship to comply with the provisions of this subsection, the applicant may apply to the Board for an exception from the terms of this subsection.
A. 
Obstructions prohibited. Sight triangles shall be required at each quadrant of an intersection of streets and streets and driveways. The area within sight triangles shall be either dedicated as part of the street right-of-way or maintained as part of the lot adjoining the street and set aside on any subdivision or site plan as a sight triangle easement. Within a sight triangle, no grading, planting or structure shall be erected or maintained more than three feet above the center-line grade of either intersecting street or driveway or lower than 12 feet above their center lines, including utility poles. Where any street or driveway intersection involves earth banks or vegetation, including trees, the developer shall trim such vegetation and trees as well as establish proper excavation and grading to provide the sight triangle.
B. 
Sight points.
(1) 
The sight triangle is that area bounded by the intersecting street lines and a straight line which connects sight points located on each of the two intersecting street lines the following distances away from the intersecting street lines:
(a) 
Streets at 130 feet.
(b) 
Primary and secondary collector street at 60 feet.
(c) 
Local streets and Class II roads at 35 feet.
(2) 
Where the intersecting streets are both collectors or one arterial and one collector, two overlapping sight triangles shall be required formed by connecting the sight points noted above with a sight point 35 feet away on the intersecting street.
C. 
Easements. Any proposed development requiring site plan approval shall provide sight triangle easements at each driveway with the driveway classified as a local street for purposes of establishing distances. The classification of existing and proposed streets shall be those shown on the adopted Master Plan or as designated by the Planning Board at the time of the application for approval for a new street not included on the Master Plan. A sight triangle easement's dedication shall be expressed on the plat as follows: "Sight triangle easement subject to grading, planting and construction restrictions provided for in the Knowlton Development Regulations Ordinance." Portions of a lot set aside for the sight triangle may be used in determining the lot area and may be included in establishing the minimum setbacks required by the zoning provision.[1]
