§ 167-1 Purpose; construction.

It is the intent of this chapter to exercise exclusive jurisdiction by the Township over all driveways into Township streets; to exercise concurrent jurisdiction with the County of Warren and the State of New Jersey Department of Transportation with respect to the portion of any driveway located within the jurisdiction limits of a county or state street or highway and to further exercise exclusive jurisdiction over those portions or driveways beyond the jurisdiction limits of those agencies. Therefore, all references contained herein to "Township road" or "public road" shall be construed to mean Township, county or state street or highway.

§ 167-2 Permit required.

A. 
Required. No person shall construct, reconstruct or enlarge a driveway into any public street or highway without first having received a permit to do so from the Township.
B. 
Classes. Permits shall be one of three classes, defined as follows:
(1) 
Class I. Single-family residential dwellings with drives not exceeding 6% maximum gradient and not requiring grading to achieve minimum sight distances required herein, having no restriction in the minimum required sight triangle and not having a bridge or culvert over four feet in diameter (or equivalent).
(2) 
Class II. All other single-family residential dwellings.
(3) 
Class III. All other driveways.

§ 167-3 Number per lot.

A. 
Number limited. The number of driveways permitted from a proposed lot or site directly to any Township road shall be limited as follows, except under conditions where the safety and/or convenience of the general motoring public is impaired. Such conditions shall be determined and specified by the Township body with authority to approve site plans upon receipt of the advice of the Township Engineer:
Length of Lot of Site Frontage On Each Street
(feet)
Permitted Number of Driveways on Each Street
150 or less
1
151 to 800

B. 
Single-family dwellings. Single-family dwellings shall not have more than one driveway.
C. 
Service stations. Service stations shall have at least two driveways.

§ 167-4 Location.

A. 
Safety. All entrance and exit driveways to a Township road shall be located so as to afford maximum safety to traffic on the Township road.
B. 
Sight distances.
(1) 
Any exit driveway or driveway lane shall be so designed in profile and grading and shall be so located as to permit the following minimum sight distances, measured from a point a minimum of 15 feet behind the curbline or edge of the traveled way of the Township road. The sight triangle shall not contain any obstruction which would obstruct the driver's view of greater than one foot nor less than 10 feet above the curb level, except that trees whose branches are trimmed away to above the ten-foot height may be permitted.

Roads which are not posted for speed limits shall be considered to be 50 mph, unless horizontal geometric considerations dictate otherwise.
C. 
Corner property. Where a site occupies a corner of two intersecting roads, no driveway entrance or exit shall be located within 40 feet of the point of tangency of the existing or proposed curb radius of that site.
D. 
Distance from sidelines. No part of any driveway shall be located within a minimum of 10 feet of a side property line. However, upon application to the Township body with authority over site plan approval, and upon approval of design by the Township Engineer, that body may permit a driveway serving two or more adjacent sites to be located on or within 10 feet of a side property line between the adjacent sites.
E. 
Distance between driveways. Where two or more driveways connect a single site to any one Township road, a minimum clear distance of 150 feet, measured along the right-of-way line, shall separate the closest of any two such drives.

§ 167-5 Geometric design.

The geometric design of a driveway connection to a Township road shall be governed by sound traffic engineering principles. Below are guidelines in preparing a geometric design, but deviation from them may be necessitated due to the many variables encountered in the course of preparing a design. The applicant should be aware, therefore, that although the driveway layout may conform to these guidelines, conditions may dictate deviations from them and requirements of the Township Engineer shall be final.
A. 
Two-way operation. Driveways used for two-way operation shall intersect the Township road at an angle as near to 90° as site conditions will permit, and in no case shall be less than 75°.
B. 
One-way operation. Driveways used by vehicles in one direction of travel, right turn only, shall not form an angle smaller than 45° with a Township road.
C. 
Dimensions.
(1) 
The dimensions of driveways shall be designated to adequately accommodate the volume and character of vehicles anticipated to be attracted daily onto the land development for which a site plan is prepared. The required maximum and minimum dimensions for driveways connecting to a Township road at 90° are indicated below. Driveways serving large volumes of daily traffic or traffic over 25% of which is truck traffic shall be required to utilize high-to-maximum dimensions. Driveways serving low daily traffic volumes or traffic less than 25% of which is truck traffic shall be permitted to use low-to-minimum dimensions.

Driveways connecting to a Township road at an angle shall have the same widths as shown in the tables above. The width of depressed curb and the radius of curb returns shall provide for the sharpest turning radii of vehicles using the driveway, keeping the vehicles within their prescribed lanes.
D. 
Vertical curves and alignment.
(1) 
Vertical curves. Any vertical curve on a driveway shall be flat enough to prevent the dragging of any vehicle undercarriage. The maximum permitted gradients for driveways are shown in the following subsection. The profile dimensions given beyond the sidewalk are maximum for grades and minimum for grades and minimum for grade lengths.
(2)

(b) 
Commercial and multifamily residential. Not greater than 4% within 100 feet of the curbline, with a maximum of 6% at any other location.
E. 
Regulations for steep ramps. Should the sidewalk be so close to the curb at a depressed curb driveway as to cause the ramp to be too steep and is likely to cause undercarriage drag, the sidewalk shall be appropriately lowered to provide a suitable ramp gradient.
F. 
Future curb or gutter line. Driveways shall be designed and constructed such that the vertical alignment requirements shall begin at the future curb or gutter line of any municipal roadway. The classification of the roadway shall be determined from the current Mansfield Township Master Plan and the width and cross-section requirements as set forth in Article XI, Streets, of Chapter 361, Design and Performance Standards, of the Township Code. The area between the existing roadway and the future curb or gutter line shall be paved and graded in accordance with the paving provisions of this chapter.
G.
