[Ord. No. 1992-32 § 9.1]
The purpose of this Article is to set forth improvement standards
and construction specifications for developments. Where a standard
in this Article is referenced as a requirement by Article 5, Zone
District Regulations, or by Article 6, Conditional Uses, or by Article
7, General Zoning Provisions, then a deviation from the specified
standard shall only be permitted when a variance is granted pursuant
to N.J.S.A. 40:55D-70. In all other cases, relief may only be authorized
as an exception to subdivision or site plan regulations pursuant to
N.J.S.A. 40:55D-51.
A subdivision and/or site plan shall conform to standards that
will result in a well-planned community, protect the health and safety
of the residents, and provide a desirable living environment without
unnecessarily adding to development costs. The following improvements
shall be required: streets and circulation, off-street parking, water
supply, sanitary sewers, and storm water management.
[Ord. No. 1992-32 § 9.2]
a.
Streets.
1.
General.
(a)
The arrangement of streets shall conform to the Master Plan.
(b)
For streets not shown on the Master Plan or official map, the
arrangement shall provide for the appropriate extension of existing
streets.
(c)
Streets shall be arranged so as to discourage through traffic
and provide for maximum privacy.
(d)
No development showing reserve strips controlling access to
another area, either developed or undeveloped, shall be approved except
where the control and disposal of land comprising such strips has
been given to the governing body after recommendation to the Board.
(e)
Developments that adjoin or include streets that do not conform
to widths as shown on the Master Plan, official map or the street
width requirements of the chapter shall dedicate additional width
along one or both sides of said road. If the development is along
one side only, 1/2 of the required extra width shall be dedicated.
(f)
The pavement width of streets and the quality of surfacing and
base materials shall adhere to the minimum standards set forth by
the Borough, County or State Engineers when said paving concerns roads
under their jurisdiction and where such standards exist.
2.
Street Hierarchy.
(a)
Streets shall be classified in a street hierarchy system with
design tailored to function.
(b)
The street hierarchy system shall be defined by road function
and traffic. The following classification shall be utilized in the
Borough and each proposed street shall be classified and designed
for its entire length to meet the described standards.
(1)
Collector streets collect traffic from local streets and channel
it into the system of arterial highways. The right-of-way width for
collector streets within the jurisdiction of the Borough is 60 feet.
The right-of-way shall have a cartway width of at least 40 feet to
allow for two twelve-foot wide moving lanes and two eight-foot wide
parking lanes. In addition, the right-of-way width shall allow for
curb, sidewalk, utility, and shade tree installation.
(c)
Local streets provide frontage for access to lots and carry
traffic having destination or origin on the street itself. The minimum
right-of-way width for local streets is 50 feet. The right-of-way
shall have a cartway width of at least 36 feet. In addition, the right-of-way
width shall allow for curb, sidewalk, utility, and shade tree installation.
Any street not designated as a collector street is a local street.
3.
Cartway Width. The determination as to cartway width shall also consider
possible limitations imposed by sight distances, climate, terrain,
and maintenance needs. The Municipal Agency may require increases
or decreases in cartway width where appropriate.
4.
Curbs, Gutters and Catch Basins.
(a)
Curbs, gutters and catch basins shall be required for drainage
purposes, safety, and delineation and protection of pavement edge.
(b)
Curbs shall be constructed according to the specifications set
forth in the construction specifications.
(c)
Curbing shall be designed to provide a ramp for bicycle and/or
wheel chairs as required.
(d)

and adjacent to the edge of all aisles, drives and off-street parking
areas.
5.
Sidewalks.
(a)
Sidewalks shall be placed in the right-of-way, parallel to the
street, unless an exception has been permitted to preserve topographical
or natural features, or to provide visual interest, or unless the
applicant shows that an alternative pedestrian system provides safe
and convenient circulation. In commercial and more intensely developed
residential areas, sidewalks may abut the curb.
(b)
Pedestrian way easements a minimum of 10 feet wide may be required
by the Planning Board through the center of blocks more than 600 feet
long to provide circulation or access to schools, playgrounds, shopping,
or other community facilities.
(c)
Sidewalk width shall be four feet; wider widths may be necessary
near pedestrian generators and employment centers. Where sidewalks
abut the curb and cars overhang the sidewalk, widths shall be six
feet.
(d)
Sidewalks and graded areas shall be constructed according to
the specifications set forth in the construction specifications.
(e)
Sidewalks shall be provided on both sides of all streets and
throughout site development for ease of pedestrian access.
6.
Utility and Shade Tree Areas.
(a)
Utilities and shade trees shall generally be located within
an easement area outside the right-of-way on both sides of and parallel
to the street right-of-way.
(b)
Utility and shade tree areas shall be planted with grass, ground
cover, or treated with other suitable cover material.
(c)
Utility and shade tree easements of at least 10 feet in width
on both sides of the street shall be provided.
7.
Right-of-way.
(a)
The right-of-way shall be measured from lot line to lot line and shall be sufficiently wide to contain the cartway, curbs, shoulders, sidewalks, graded areas, utilities and shade trees. (See Subsection 40-9.2a2.)
(b)
The right-of-way width of a new street that is a continuation
of an existing street shall in no case be continued at a width less
than the existing street.
(c)
The right-of-way shall reflect future development as indicated
by the Master Plan.
10.
Lighting.
(a)
Lighting shall be provided in accordance with a plan designed
by the utility company, or using as a guideline the standards set
forth by IES Lighting Handbook shown in the construction specifications.
(b)
Lighting for safety shall be provided at intersections, along
walkways, at entryways, between buildings, and in parking areas.
(c)
Spacing of standards shall be equal to approximately four times
the height of the standard.
(d)
The maximum height of standards shall not exceed the maximum
building height permitted, or 25 feet, whichever is less.
(e)
The height and shielding of lighting standards shall provide
proper lighting without hazard to drivers or nuisance to residents,
and the design of lighting standards shall be of a type appropriate
to the development and the municipality.
(f)
Spotlights, if used, shall be placed on standards pointing toward
the buildings and positioned so as not to blind the residents, rather
than on the buildings and directed outward which creates dark shadows
adjacent to the buildings.
11.
Underground Wiring.
(a)
All electric, telephone, television, and other communication
facilities, both main and service lines servicing new developments,
shall be provided by underground wiring within easements or dedicated
public right-of-way, installed in accordance with the prevailing standards
and practices of the utility or other companies providing such services.
(b)
Lots which abut existing easements or public rights-of-way where
overhead electric or telephone distribution supply lines and service
connections have 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 under-ground.
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.
(c)
Where overhead lines are permitted as the exception, the placement
and alignment of poles shall be designed to lessen the visual impact
of overhead lines as follows: Alignments and pole locations shall
be carefully routed to avoid locations along horizons; clearing swaths
through treed areas shall be avoided by selective cutting and a staggered
alignment; trees shall be planted in open areas and at key locations
to minimize the view of the poles and the alignments; and alignments
shall follow rear lot lines and other alignments.
(d)
Year-round screening of any utility apparatus appearing above
the surface of the ground, other than utility poles, shall be required.
12.
Street Name and Traffic Control Signs.
(a)
Street signs shall be reflectorized aluminum with the street
name in white letters four inches high on a green background. The
mounting height of the sign shall be 12 feet.
The street signs shall be metal and conform with existing signs
as approved by the Borough Engineer.
(b)
At least two street name signs shall be placed at each four-way
street intersection and one at each "T" intersection.
(c)
Where traffic control signs are deemed necessary by the Board,
subdivider of Borough Engineer for Borough, County or State highways,
the proper Borough, County or State official shall be informed of
the proposed installation in order that the proper agency may consider
the necessity of the installation at its own expense.
(d)
All street name and traffic control signs shall be installed
free of visual obstruction.
(e)
The names of newly developed streets and street name changes
shall be approved by the Borough Council.
b.
Off-Street Parking.
1.
Number of Spaces.
(a)
Off-street parking spaces shall be required in all developments,
except as provided herein, to accommodate residents and visitors.
(b)
For residential developments, off-street parking shall be provided
as set forth in Exhibit 40-9-1.
(c)
For nonresidential developments, off-street parking shall be
as set forth in Exhibit 40-9-2.
(d)
Alternative off-street parking standards shall be accepted only
if the applicant demonstrates that these standards better reflect
local conditions.
(e)
The Municipal Agency may require the use of alternative standards
if it determines that the chapter standards are insufficient or a
particular development has a unique parking requirement. The basis
for such a determination shall be documented by the Municipal Agency
in its minutes.
(f)
Where the total number of off-street parking spaces required
may not be immediately required for a particular use, a staged development
plan may be permitted which requires that only a portion of the parking
area, but not less than 65% of the required spaces be completed initially,
subject to the following regulations:
(1)
The site plan shall clearly indicate both that portion of the
parking area to be initially paved and the total parking needed to
provide the number of spaces required.
(2)
The site plan shall provide for adequate drainage of both the
partial and total parking areas.
(3)
The portion of the parking area not to be paved initially shall
be landscaped in accordance with Article 8.
(4)
The applicant shall post separate performance guarantees, in
addition to the performance guarantees required under Article 10 which
shall reflect the cost of installing the additional parking facilities
necessary to provide the total number of parking spaces required.
(5)
In lieu of a permanent Certificate of Occupancy, a temporary
Certificate of Occupancy shall be issued for a period of two years.
Prior to the expiration of the two-year period, the applicant may
either install the additional parking spaces shown on the site plan
and apply for issuance of a permanent Certificate of Occupancy or
apply to the Planning Board after the use has been in operation a
minimum of 18 months for a determination as to whether or not the
initial parking area provided is adequate. If the Planning Board determines
that the parking facility is adequate as originally constructed, the
performance guarantees shall be released and a permanent Certificate
of Occupancy issued. If, however, the Planning Board determines that
the partial off-street parking area is not adequate, the applicant
shall be required to install the additional parking facilities in
accordance with the terms of the performance guarantees prior to issuance
of a permanent Certificate of Occupancy.
(6)
Any change of use on a site for which the Planning Board may
have approved a partial paving of off-street parking areas to a use
which requires more parking spaces than are provided on the site shall
require submission of a new site plan.
(g)
Uses along that portion of Belmar east of Ocean Avenue consisting
entirely of improvements on or abutting the boardwalk shall be exempt
from the off-street loading and off-street parking requirements of
this chapter.
(h)
The total number of parking spaces required based on Exhibits 40-9-1 and 40-9-2 shall include the number of handicapped parking spaces required under Subsection 40-9.2b4 of this chapter.
(i)
Within the CBD-1 district, off-street parking shall be provided
in public parking lots or shared use parking lots. New development
in the CBD-1 shall be required to show that under a shared use approach,
adequate parking will be available in a public or a shared use lot.

In computing the number of required parking spaces, the following
shall apply:
| |
|
1)
|
Where fractional spaces result, the required number shall be
construed to be the next highest whole number.
| |
|
2)
|
The parking space requirements for a use not specifically mentioned
herein shall be the same as required for a use of similar nature to
those enumerated in Exhibit 40-9-1 or 40-9-2 as determined by the
Municipal Agency.
| |
|
3)
|
If there is no use enumerated herein sufficiently similar to
the use proposed to enable the Municipal Agency to establish rational
parking requirements, the Municipal Agency may, in its discretion,
direct the applicant to furnish the Municipal Agency with such data
as may be necessary to enable the Municipal Agency to establish rational
parking requirements.
| |
|
**
|
Bar, Restaurant, or similar uses shall be calculated separately.
| |
|
***
|
A building of mixed office uses may include a maximum of 1/3
medical or dental floor area. If medical or dental uses exceed one-third
of the gross floor area, their parking requirement shall be computed
separately.
| |
|
****
|
If more than 25% of the total floor area is occupied by a non-retail
use which has off-street parking requirements greater than those required
for a shopping center, then off-street parking for the center shall
be the same as the required minimum for the non-retail use plus the
required minimum for the balance of the shopping center floor area.

f.
Stormwater Management.
1.
Purpose.
(a)
It is hereby determined that the waterways within the Borough
of Belmar are at times subjected to flooding; that such flooding is
a danger to the lives and property of the public; that such flooding
is also a danger to the natural resources of the Borough of Belmar,
the County and the State; that development tends to accentuate flooding
by increasing storm water runoff, due to alteration of the hydrologic
response of the watershed in changing from the undeveloped to the
developed condition; that such increased flooding produced by the
development of real property contributes increased quantities of waterborne
pollutants, and tends to increase channel erosion; that such increased
flooding, increased erosion, and increased pollution constitutes deterioration
of the water resources of the Borough of Belmar, the county and the
state; and that such increased flooding, increased erosion and increased
pollution can be controlled to some extent by the regulation of stormwater
runoff from such development. It is therefore determined that it is
in the public interest to regulate the development of real property
and to establish standards to regulate the additional discharge of
stormwater runoff from such developments as provided in this chapter.
(b)
The stormwater management plans submitted shall demonstrate
careful consideration of the general and specific concerns, values
and standards of the municipal Master Plan and applicable County,
regional and State storm drainage control program, any county mosquito
commission control standards, and shall be based on environmentally
sound site planning, engineering and architectural techniques.
(c)
Development shall use the best available technology to minimize
off-site stormwater runoff, increase on-site infiltration, simulate
natural drainage systems, and minimize off-site discharge of pollutants
to ground and surface water and encourage natural filtration functions.
Best available technology may include measures such as retention basins,
recharge trenches, porous paving and piping, contour terraces and
swales.
2.
System Strategy and Design.
(a)
Stormwater management system strategy and design shall comply
with the specifications set forth in the construction specifications.
3.
Detention — When Required.
(a)
Detention will be provided for all major subdivisions and all
major site plans resulting in more than 10,000 square feet of impervious
surface such that after development the peak rate of flow from the
site will not exceed the corresponding flow which would have been
created by similar storms prior to development.
[Ord. No. 1992-32 § 9.3]
Where there is a question as to a specific requirement, the
Standard Specifications of N.J.D.O.T. Road and Bridge Construction
shall apply.
