				All new interstate highway improvements shall conform to these standards. The
				geometric design of the interstate system shall, at a minimum, comply with the
				standards presented in the publications; but the design of traffic barriers and
				drainage systems shall conform to the "New Jersey Department of Transportation
				Roadway Design Manual." If these standards prove to be infeasible, the highway
				improvements shall be designed to the interstate standards that were in effect
				at the time of the original interstate construction.
c. For municipal, county, or private roadways, the design
				standards found in the AASHTO publication "A Policy on Geometric Design of
				Highway and Streets" for the appropriate functional classification shall govern
				unless superseded by other governmental regulations. Information on
				availability of this publication is referenced above.
E-2 Driveway Design Parameters
E-2.1 General Provisions
a. All driveways shall be designed to enable vehicles to leave
				the State highway without restriction, queuing, or hesitation on the State
				highway, and enter the State highway in a safe manner.
b. Driveways shall not be approved for off-street parking areas
				that require backing maneuvers within the State highway ROW.
c. All portions of a driveway shall be constructed within the
				extended lot lines (E.L.L. in Figure E-1 below) unless a permanent easement for
				shared use with an adjacent lot or site owner is contained in the recorded deed
				for both properties.
d. The area between driveways and extending from the curbline
				to the ROW line shall be raised six inches above the surface of the adjacent
				driveways and seeded, sodded, or otherwise improved to delineate and limit the
				driveway.
E-2.2 Emergency Driveways
a. Emergency driveways shall not have depressed curbs or curb
				returns.
b. Emergency driveways shall not be paved, but shall be
				strengthened by gravel or pavers over which grass shall be grown.
c. An existing or proposed sidewalk across an emergency
				driveway shall be strengthened to support emergency vehicles.
d. Emergency driveways shall have sufficient length in advance
				of any gate to allow the emergency vehicles anticipated to utilize the driveway
				to temporarily park in the driveway without interfering with State highway
				traffic.
E-2.3 Driveway Features
Table E-1 provides ranges of minimum and maximum dimensions
				that can be used for various driveway features. These dimensions are allowable
				ranges and the actual designs should be based on sound engineering judgment and
				approved by the Department. Single-family residential lots and combined
				single-family residence and business lots are considered residential in the
				parameters outlined below. All other lots or sites, including lots with
				multiple single-family residences, are considered non-residential. The
				abbreviations noted in parentheses are those shown in Figure E-1 that
				follows.
TABLE E-1--DRIVEWAY DIMENSIONS

							 Bifurcated Driveways

							 to centerline of the curbline openings of the ingress and egress
							 points

							 possible; 60 degrees minimum
Radius (R)

Radii shall be designed to accommodate the specific
							 design vehicle as approved by the Department and the allowance or prohibition
							 of proposed turning movements into or out of the driveway
Corner Clearance

Non-residential
50 feet minimum from non-signalized intersections for
							 roadways designated AL 6, roadways that have posted speed limits of 25 miles
							 per hour, or roadways that have paved shoulders at least 10 feet wide
100 feet minimum for all other roadways
Driveway Grades
Residential or Non-residential
All--Four percent maximum within 25 feet of
							 curbline

Residential or Non-residential
All--25 feet minimum
Driveway Islands
Residential or Non-residential
Offset a minimum of three feet from curbline
Minimum area shall be 75 square feet
Off-street parking areas
Shall be designed to prohibit vehicles from backing
							 up into the driveway within 50 feet of the curbline opening
Shall include on-site maneuvering areas and aisles to
							 perm vehicles to enter and exit the lot or site without hesitation
Gates
Shall be located a minimum of 50 feet from the
							 curbline
Shall provide for U-turns without the need for
							 vehicles to back onto the highway or shoulder
No gates shall be constructed within State highway
							 ROW

E-2.4 Drainage and Driveway Grades
a. Connections to the Department's drainage system shall not be
				permitted unless approved by the Department. In no case shall the Department's
				drainage capacity be diminished by these connections.
b. Figure E-2 below shows driveway profile controls and
				illustrates the following:
1. The use of a swale or pipe underdrain for proper drainage of
				uncurbed portions of highway is indicated.
2. The bottom profile shows a driveway sloping upward to the
				sidewalk to assure proper drainage.
3. Beyond the sidewalk the driveway may slope either upward or
				downward depending upon the topography at the lot or site.
4. The grade of the driveway should fit the plane of the
				driveway where curbs are used along the roadway and sidewalks are provided or
				contemplated. If the difference in elevation of the curbline and the sidewalk
				is such that this is not practical, then the sidewalk should be lowered to
				provide a suitable grade for the driveway. In such a case, the surface of the
				sidewalk should be sloped gently from either side of the driveway.
5. Vertical curves on driveways should be flat enough to
				prevent dragging of the vehicle undercarriage and to provide adequate sight
				distance.
