Any land development subject to County review and approval shall
provide on its lot the number of off-street parking and loading and
unloading spaces required by the zoning, subdivision, site plan or
other ordinance of the municipality in which the land development
is to be located. In addition to local requirements, the following
criteria are to be accounted for in the design of off-street parking
and loading facilities for developments subject to review and approval
by the County.
A. Off-street parking facilities shall be designed to prevent the storage
of any vehicles upon any portion of the existing or future County
right-of-way, including the sidewalk area, and within any portion
of an entrance driveway or driveway lane that is within 20 feet of
the County right-of-way.
B. Off-street parking facilities shall be designed to permit all vehicles
to maneuver from an access driveway, aisle or parking space without
encroaching upon any portion of the existing or future County right-of-way,
including the sidewalk area.
C. Off-street parking facilities shall be designed to permit all vehicles
to turn around on the site to prevent the necessity of any vehicle
having to back onto the County road from the site.
D. Sufficient reservoir space shall be provided at the entrance drive
to prevent queued entering vehicles from spilling back across the
existing or future right-of-way of the County road, including the
sidewalk area.
E. Entrance and exit lanes shall be clearly signed in order to prevent
driver confusion.
F. No part of any off-street truck loading or unloading space shall
be located within the right-of-way of any County road. On-site truck
loading berths shall be designed in accordance with the current edition
of the ITE's Transportation and Traffic Engineering Handbook.
G. Off-street truck loading and unloading spaces shall be located and
designed to permit any truck to maneuver from a driveway into and
out of such spaces without encroaching upon any existing or future
County-owned right-of-way, including the sidewalk area.
H. The truck-circulation patterns shall be designed to avoid interference
with automobile and pedestrian movements or with high-turnover parking.
Truck loading docks shall be located away from areas of pedestrian
movement and screened from view of parking areas, adjacent properties
or adjacent streets.
I. Parking stalls shall be a minimum of nine feet wide by 18 feet long.
J. The DRC may require the applicant to enter into a shared parking
agreement if adequate off-street parking cannot be provided on-site.
The applicant must prove that the shared parking facility has an adequate
number of additional parking spaces and is available during nonconflicting
hours of operation. A copy of the shared parking agreement shall be
submitted to the County for review prior to final approval by the
DRC.
K. Off-street parking areas and driveways for residences or residential
uses shall also be designed to prevent vehicles from backing onto
a County road.
L. Electric vehicle charging stations should be incorporated into site
designs where appropriate.
The intent of the land development standards is to review all
development within Atlantic County in accordance with the requirements
of the Americans with Disabilities Act.
A. The number of parking spaces for individuals with disabilities shall
be in accordance with the New Jersey Uniform Construction Code (N.J.A.C.
5:23-7) or the Americans with Disabilities Act, as applicable.
B. Parking spaces for individuals with disabilities shall be located
as close as possible to elevators, ramps, walkways and the accessible
entrance(s) they serve. They shall be no more than 200 feet from an
accessible entrance.
C. Parking spaces for individuals with disabilities shall be as level
as possible with surface slopes not exceeding 1:48 (1/4 inch per foot)
in any direction.
D. Each parking space shall be marked with an R7-8 sign from the Manual
of Uniform Traffic Control Devices displaying the international symbol
of accessibility.
E. Parking spaces for individuals with disabilities shall be a paved
surface that is suitable for wheeling and walking. Such parking spaces
shall allow room for individuals in wheelchairs or individuals on
braces and crutches to get in and out of either side of a vehicle.
F. Curb cut ramps shall be provided to permit individuals with disabilities
access from the parking area to the parking lot.
If warranted, the Development Review Committee may require one
or more of the following improvements along a County road in order
to facilitate the safe and efficient movement of vehicular and pedestrian
traffic.
A. Traffic signal.
(1) The DRC may require the installation of a new traffic signal or modification
of an existing signal at the intersection of a County road when a
subdivision or site plan application will generate a significant increase
in traffic volume, create a traffic safety hazard or other situations
sufficient to warrant a traffic signal. All traffic signals must be
warranted and shall be designed in accordance with the Manual on Uniform
Traffic Control Devices, latest edition, (MUTCD)
(2) In accordance with the MUTCD, a traffic signal warrant study shall
be prepared to determine whether a traffic signal device or modification
of an existing traffic signal is justified. In addition, the design
engineer is required to provide a recommendation that if warranted,
the signalization is based on their analysis and investigation and
that the signalization is in the best interest of safety and the expeditious
movement of traffic.
(3) The design engineer shall obtain NJDOT's approval that a traffic
signal is warranted prior to starting the design of the traffic signal.
The Development Review Committee will require that the applicant prepare
and have approved by the County Engineer and the New Jersey Department
of Transportation all necessary plans and specifications for the traffic
signal.
(4) The applicant/developer shall be responsible for and bear the expense
of securing such approvals as may be required, including the bonding
and the costs of installation of the traffic signal in accordance
with approved plans.
B. Traffic control devices. In accordance with the Manual on Uniform
Traffic Control Devices, latest edition, (MUTCD), the DRC may require
the installation of traffic control devices such as specific directional,
regulatory or advisory signs, signals, channelization, traffic striping
or raised pavement markings at designated locations on the site or
in the County right-of-way. Material specifications for traffic control
devices are to be in accordance with the NJDOT's Standard Specifications
for Road and Bridge Construction, latest edition.
C. Auxiliary lanes.
(1) Widening of the County road, construction of shoulders and auxiliary
lanes (acceleration/deceleration, turning lanes) may be required by
the DRC. Factors governing this determination shall include roadway
classification, current and anticipated traffic volume, speed on the
County road, safety concerns or conditions and the character and volume
of traffic on the street or road. Auxiliary lanes shall be in accordance
with Figure 16 and Figure 18.
(2) If warranted the following auxiliary lanes shall be provided:
(a)
Right-turn deceleration lane. A right-turn deceleration lanes
shall be provided for all developments along those County roads classified
as "arterial" in the Official County Map Right-Of-Way Standards in
the County Master Plan.
(b)
Left-turn storage lane.
[1]
A left-turn storage lane shall be provided when the proposed
development meets the warrant for a left-turn storage lane as described
by Highway Research Record Number 211.
[2]
The DRC may also determine that safety conditions warrant a
left-turn storage lane after review of accidents in the past three
years, existing traffic volumes, speed limits, sight distances and
roadway alignment.
D. Marginal service road. The DRC may require a marginal service road
that runs parallel to a higher order street which provides access
to abutting properties and separation from through traffic. It may
be designed as a residential access street or minor collector as anticipated
daily traffic dictates.
E. Common driveways or common access roads. Common driveways or common
access roads shall be provided for those lots fronting a County road
and not having access to a municipal street.
F. Limited access. Access to a County road may be limited to right turn
in/right turn out movements, one-way entrances or exits or similar
types of turning restrictions.
G. Pedestrian and bicycle accommodations. Pedestrian and bicycle scale
signals should be incorporated where feasible. Any intersection with
sidewalk connections to residential neighborhoods and commercial or
other destinations should include pedestrian-actuated call buttons
that conform to ADA standards. For intersections where bike lanes
are present, consideration should be given to providing priority signals
for cyclists.
H. Other improvements. Other improvements may be deemed necessary by
the DRC for the safe and efficient operation of an existing or proposed
County intersection.
Each land development subject to County approval may be required
to install curb or curb with gutter for stormwater management purposes,
protection of vehicular and pedestrian traffic, and delineation and
protection of the pavement edge.
A. Requirements. Curb and curb with gutter may be required to:
(1) Channelize vehicular traffic.
(2) Maintain existing stormwater flow or correct an existing drainage
problem.
(3) Match and maintain the continuity of curbing on adjacent property.
(4) Protect pedestrians when sidewalk exists or is to be installed.
B. Standards. All curb and curb and gutter to be installed within a
County right-of-way shall conform to the standards and specifications
below:
(1) Curb offsets shall be based on those identified in Table 2: County
Roadway Standards and the existing conditions in the area.
