Except as otherwise provided in this chapter, the design standards for streets, roadways, curbs, sidewalks, driveways, signs, lights, storm drainage, water mains, sanitary sewers and related improvements shall meet the requirements of and be constructed, installed and located in accordance with "Standard Construction Details and Specifications, Township of Mine Hill, County of Morris, New Jersey," dated February 1976, prepared by John Cilo, Jr., P.E. and L.S., Township Engineer, consisting of two sheets of drawings, copies of which were attached to and made part of the Township Road Specification Ordinance adopted April 8, 1976. Said construction specifications are hereinafter referred to as "Township Standard Construction Details" and are incorporated herein and made a part hereof as if set forth in full.
A. Street right-of-way and pavement widths.
(1) Primary or arterial streets (used primarily for fast or heavy traffic):
(a) Right-of-way width: 66 feet (or width of the existing street which is being extended, if greater).
(2) Collector streets (used to carry traffic from minor streets to arterial or primary streets):
(a) Right-of-way width: 60 feet (or the width of the existing street which is being extended, if greater).
(3) Minor streets (used primarily for access to abutting properties):
(a) Right-of-way width: 50 feet.
(c) Minor streets shall be designed so as to discourage through traffic.
(4) Marginal access streets (a street parallel or adjacent to an arterial street or highway and which provides access to abutting properties and protection from through traffic):
(a) Right-of-way width: 50 feet.
(5) Cul-de-sac or dead-end turnarounds. Cul-de-sac or dead-end turnarounds shall have a minimum radius of 50 feet on the curb, with a right-of-way radius of 60 feet.
(6) Internal roads. The right-of-way and pavement widths for internal roads in multifamily, commercial and industrial developments and zones shall be determined on an individual basis and shall in all cases be of sufficient width and design to safely accommodate the maximum traffic, parking, loading, and access for firefighting equipment, but in no case shall such widths be less than those required herein for marginal access streets or the pavement and design less than "Class B" road specifications as hereinafter set forth.
(7) Sight triangle. At all street intersections, fences, landscaping, grading or other obstruction to vision exceeding 24 inches in height above the established grade of the street at the property line shall not be erected or maintained on any lot within the triangle formed by a line drawn between a point 100 feet distant along the main street sideline and a point 30 feet distant along the side street sideline from their point of intersection.
(8) Widening existing streets. Developments that include existing streets which do not conform to pavement and/or right-of-way widths as shown on the Master Plan or Official Map shall dedicate and improve to Township specifications additional width along the side or sides of said road abutting the property being developed. If the development adjoins one side of an existing road which does not meet standards, only 1/2 of the required extra width shall be dedicated and improved to Township specifications.
B. Street pavement specifications.
(1) All materials and methods of road construction shall be in accordance with the specifications approved and followed by the New Jersey Department of Transportation as set forth in its manual entitled "Standard Specifications for Road and Bridge Construction of the New Jersey State Highway Department," dated 1961, as amended, supplemented and revised.
(2) All streets (roads) shall be designed, constructed and paved in accordance with "Class A" road specifications as follows:
(a) Two inches (compacted) FABC-1 (mix No. 5) surface course on five inches bituminous stabilized base course (stone mix No. 1) on a subbase of three inches (minimum) of soil aggregate Type 5, Class "A" on an approved subgrade.
(b) Where conditions warrant, alternative pavement designs in accordance with the Asphalt Institute Manual Series No. 1 (MS-1), Revised, Eighth Edition, August 1970, may be submitted for consideration and approval to the Township Planning Board.
(3) Where "Class A" specifications are determined by the Planning Board to be inappropriate with respect to the construction of marginal access streets, the extension of existing minor streets or marginal access streets, or the construction of internal roads in multifamily, commercial or industrial developments, taking into consideration existing conditions, the right-of-way and pavement widths of existing streets adjoining the area(s) in question, and the type of construction of such adjoining street or streets being extended, the Planning Board may approve upon request of the developer and recommendation of the Township Engineer the construction of roads in accordance with "Class B" road specifications, as follows:
(a) Two inches (compacted) FABC-1 (Mix No. 5) surface course on five inches bituminous stabilized base course (stone mix No. 1) on a subgrade approved by the Township Engineer.
C. Street design standards.
(1) Grades. Grades of arterial and collector streets shall not exceed 6%. Grades of all other streets (roads) shall not exceed 12%. No street shall have a minimum grade less than 0.5%.
(2) Curbing.
(a) Curbing shall be constructed on both sides of all streets.
(b) Granite block curbing shall be constructed unless concrete curbing is required to meet requirements for state or county roads, or is deemed more appropriate by the Township Planning Board on the recommendation of the Township Engineer, based upon existing conditions.
(c) Granite block and concrete curbing shall be constructed, installed and located in accordance with "Township Standard Construction Details."
(3) Intersections. Street intersections shall be laid out as nearly at right angles as possible and in no case shall be less than 70°. The block corners at intersections shall be rounded at the curbline with a curb having a radius of not less than 35 feet. Sight easements shall be provided by developer at street intersections and/or at curves or deflection points on streets in order to allow for proper sight distance, wherever deemed necessary by the Planning Board on advice from the Township Engineer.
(4) Jogs. Street jogs with center-line offsets of less than 125 feet shall be prohibited.
(5) Reverse curves. A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets.
(6) Connecting streets. When connecting street lines deflect from each other at any one point by more than 10° and not more than 45°, they shall be connected by a curve with a center-line radius of not less than 300 feet for minor streets and 600 feet for arterial and collector streets.
(7) Grade changes. All changes in grade shall be connected by vertical curves of sufficient radius to provide a smooth transition and proper sight distance.
(8) Dead-end streets. All dead-end streets shall not be longer than 600 feet and shall have a turnaround installed with a curb radius of 50 feet and shall be tangent wherever possible to the right side of the street. When a dead-end street terminates at an adjoining property line and where it is possible to extend the street at a future time, the turnaround right-of-way shall be considered temporary in nature, and provision shall be made for future extension of the street and reversion of the excess right-of-way to the adjoining property or properties. Wherever a temporary or permanent turnaround is proposed on any street, the front yard setback line shall be measured from the right-of-way line of the turnaround.
D. Sidewalks.
(1) Sidewalks shall be concrete, with a minimum width of four feet and a minimum thickness of four inches.
(2) Sidewalks shall be constructed on both sides of all new streets or on extensions of all existing streets, unless deemed inappropriate and waived by the Township Planning Board on the recommendation of the Township Engineer, taking into consideration existing conditions, including the location of sidewalks, if any, on adjoining and nearby streets.
(3) All sidewalks shall be constructed in accordance with "Township Standard Construction Details."
E. Driveways. Driveway openings, aprons, and widths shall be constructed and located in accordance with "Township Standard Construction Details" and shall not have a grade in excess of 15% within 40 feet of the road right-of-way and shall meet the street at grade unless otherwise approved by the Planning Board. Wherever appropriate, driveways shall be so designed as to allow vehicles to turn around on the lot in order to make it unnecessary to back any vehicle onto the street.
F. Parking areas.
(1) All parking and loading areas shall be paved with two inches (compacted) FABC-1 (mix No. 5) surface course on three inches bituminous stabilized base course (stone mix No. 1) on a subgrade approved by the Township Engineer. Provision shall be made for adequate drainage facilities for all parking, loading and storage areas. All such installations shall be connected with an adequate approved system and shall be adequate to accommodate the storm drainage runoff of the facility it is designed to serve. All drainage facilities shall be approved by the Township Engineer prior to Planning Board approval.
(2) All parking spaces within any parking area shall be clearly marked and maintained to show the parking arrangement within said parking area.
(3) All lighting for off-street parking areas shall be so arranged and shielded as to reflect the light downward and prevent any light from shining directly on adjoining streets, residential zones and residential buildings.
(4) All parking areas shall be effectively screened on any side which abuts or faces any premises situated in any residential zone, by a fence, wall or hedge at least five feet in height, maintained in good condition, if required by the site plan approved by the Planning Board; provided, however, that such fence, wall or hedge may be waived by the Planning Board if, because of topographic or other extraordinary or exceptional conditions, the same shall not be necessary to protect any abutting or facing premises situated in any residential zone.
(5) If any fence, wall or hedge shall have been required for any parking area, then said fence, wall or hedge shall be protected by a concrete curb or bumper guard, or the equivalent, which shall run parallel to said fence, wall or hedge, be at least five inches in height above the paved surface adjacent to said fence, wall or hedge, and be a sufficient distance therefrom to protect said fence, wall or hedge from the impact of motor vehicles. Utility poles or railroad ties shall not be used to meet required curbing or bumper guards.
(6) If any parking area shall have been permitted in any front yard, the Planning Board shall have the power to require a concrete curb, bumper guard, or the equivalent, at least five inches in height above the paved surface, along and parallel to any landscaped area in the front yard as sufficient to protect the same from the impact of motor vehicles.
(7) All parts of all yards not used for off-street parking areas shall be adequately landscaped, subject to approval by the Planning Board, and maintained in good condition.
(8) All such parking areas shall be used only for the parking of automobiles. No commercial repair work or sales of any kind shall be conducted in any parking areas. No sign other than entrance, exit, identification and conditions of use signs shall be maintained in any parking area. No such sign shall be larger than four square feet in area. Nothing herein contained shall be construed to permit any required parking area to be used for the commercial storage of new or used motor vehicles by a new or used car dealer or motor vehicle rental agency.
(9) All parking areas and structures shall be provided with adequate means of ingress and egress which shall be kept open and unobstructed at all times and which shall be designed to provide service driveways or aisles to meet the minimum standards as provided in the Zoning Ordinance of the Township as amended and reenacted by Part
6, Zoning, of this chapter.
(10) Generally, the requirements and design standards for off-street parking in the Zoning Ordinance of the Township shall be met.
