The standards of the City of Somers Point, as
established within the various zoning districts of the city and as
listed in this article, are to be considered minimum. Prior to the
granting of final approval for a subdivision or site plan, the developer
shall have installed improvements required by the Planning Board or
have posted a performance guaranty sufficient to cover the costs of
said improvements. Improvements may include those recommended by state
and county agencies which have participated in the review. Construction
standards and required improvements are intended to protect the general
health, safety and welfare. In certain instances all of the improvements
listed in this article may not be appropriate, in which case the Planning
Board may issue a waiver. Standards established within this chapter
and those ordinances hereafter adopted by the city shall govern design,
construction and installation of improvements within the City of Somers
Point by a subdivider, developer, constructor or agent. Failure to
conform to these specifications shall be just cause for suspension
of work without right to claim damages from the city, its officers
or agents for such stoppage.
In the event that the city has not adopted standards
for a specific type of improvement, generally accepted engineering
standards, as set forth in accepted engineering and construction manuals
and modified as necessary by the City Engineer, shall be used.
Prior to construction, all stakes and grades
shall be set by a licensed land surveyor and a set of the notes resulting
shall be filed with the City Engineer. Before work commences, the
City Engineer shall be notified, and under no circumstances shall
underground work be covered until inspected by the appropriate official.
If, during construction, the subdivider/developer fails to meet specified
requirements or to correct unacceptable work, he shall be notified
of such failure by certified mail, return receipt requested, with
instructions for correcting the situation. If corrections have not
been made within 10 days, the city shall serve the subdivider/developer
with notice of failure to comply, with a copy to the Planning Board,
and work may be suspended.
A.
Prior to and during construction, no topsoil shall
be removed from the site or utilized as fill without approval of the
Construction Official or City Engineer. Soil displaced by construction
shall be redistributed so as to provide a six-inch base throughout

specifications are not included, Standard Detailed Specifications
of the New Jersey Department of Transportation, latest revision, shall
govern.
[Amended 11-29-1984 by Ord. No. 29-1984]
A.
General standards.
(1)
Channeling runoff directly to water bodies is
discouraged. Instead, runoff should be routed through swales and other
drainage systems designed to increase the time of concentration, decrease
the velocity, increase infiltration and allow suspended material to
settle.
(2)
Natural watercourses should not be dredged,
cleared of vegetation, deepened, widened, straightened, stabilized
or otherwise altered without a stream encroachment permit from New
Jersey Department of Environmental Protection, Division of Water Resources,
Bureau of Flood Plain Management. Water should be retained or detained
before it enters any natural watercourse in order to preserve the
natural hydrodynamics of the watercourse and to prevent siltation
or other forms of pollution.
(3)
Retention and detention facilities should be
used to retain and detain the increased and accelerated runoff which
the development generates. Water should be released from detention
facilities into watercourses or wetlands at a rate and in a manner
approximating the natural flow which occurred before development.
Care must be taken, since the design of detention and/or retention
facilities without an associated analysis of downstream impact can
create increased stormwater runoff problems even when a stormwater
management system is in place.
(4)
The sides of detention and/or retention basins
should slope at a gentle grade into the basin bottom as a safeguard
against drowning and personal injury and to ensure the structural
integrity of the facility.
(5)
The bottom of all proposed retention structures
should be at least two feet above any impervious soil formations and/or
the seasonal high-water table found in the soil logs.
(6)
Runoff from parking areas should incorporate
measures (i.e., grit, and oil chamber or sediment traps) to prevent
oil and sediment from entering receiving waters and/or clogging the
interstices preventing infiltration in subsurface recharge and/or
retention facilities.
(7)
Artificial watercourses, such as swales, should
be designed considering soil type, so that the velocity of flow is
low enough to prevent erosion.
(8)
Intermittent watercourses, such as swales, should
be vegetated.
(9)
The area of land disturbed by development should
be as small as practicable (footprint-only removing the vegetation
necessary to build the structure). Those areas which are not to be
disturbed should be protected by an adequate barrier from construction
activity using acceptable soil erosion and sedimentation control techniques.
Whenever possible, natural vegetation should be retained and protected.
(10)
Although the use of wetlands for storing and
purifying water is sometimes encouraged, care must be taken not to
overload their capacity, thereby harming wetlands and transitional
vegetation. Wetlands should not be damaged by construction of detention
ponds.
(11)
Wetlands and other water bodies should not be
used as sediment traps during development.
(12)
Vegetated buffer strips should be created or,
where practicable, retained in their natural state along the banks
of all watercourses, water bodies or wetlands. The width of the buffer
should be sufficient to prevent erosion, trap the sediment carried
with overland runoff, provide access to the water body and allow for
periodic flooding without damage to structures.
(13)
The use of drainage facilities and vegetated
buffer zones as open space, recreation and conservation areas should
be encouraged.
(14)
Erosion and sedimentation facilities should
receive regular maintenance during construction to ensure that they
continue to function properly.
(15)
No grading, cutting or filling should be commenced
until the plan is approved by the municipality, County Planning Board
and the Soil Conservation District (SCD).
(16)
Land which has been cleared for development
and upon which construction has not commenced should be protected
from erosion by appropriate techniques designed to revegetate the
area.
(17)
Adherence to the development time schedule contained
in the erosion and sediment control plan should be followed.
(18)
Sediment should be retained on the development
site.
(19)
Volumes and rate of runoff are to remain at
predevelopment levels for the two-, ten-, and fifty-year storm.
(20)
The maintenance cost of all on-site stormwater
collection and management systems is to be borne by the owner. The
responsibility for maintenance of off-site facilities is to be determined
by the reviewing body at the time of preliminary review and approval.
[Amended 10-27-1988 by Ord. No. 16-1988]

C.
No land area, except for single- or two-family residential
construction not part of a major subdivision, shall be developed such
that:
(1)
The volume and/or rate of stormwater runoff
occurring at the area is increased over what occurred there under
conditions existing on or before the effective date of this chapter.
(2)
The drainage of adjacent areas is adversely
affected.
(3)
Soil erosion during and after development is
increased over what naturally occurs there.
(4)
Soil absorption and groundwater recharge capacity
of the area is decreased below the conditions existing on or before
the effective date of this chapter.
(5)
The natural drainage pattern of the area is
significantly altered.
E.
In order to duplicate as nearly as possible natural
drainage conditions, regulation and control of stormwater runoff and
erosion shall be through on-site stormwater detention and/or ground
absorption systems, which include but are not limited to, the following:
(1)
Detention areas, which may be depressions in
parking areas, excavated basins or basins created through use of curbs
or any other form of grading which serves to temporarily impound and
store water.
(2)
Rooftop storage through temporary impoundment
and storage of stormwater on flat or slightly pitched building rooftops
by use of drain outlets, which restrict the stormwater runoff from
the roof surface.
(3)
Dry wells or leaching basins which control stormwater
runoff through ground absorption and temporary storage.
(4)
Porous asphaltic pavement, which preserves the
natural ground absorption capacity of a site and provides a subsurface
reservoir for temporary storage of stormwater.
(5)
Any system of porous media, such as gravel trenches
drained by porous wall or perforated pipe, which temporarily stores
and dissipates stormwater through ground absorption.
(6)
Any combination of the above-mentioned or other
techniques, as approved by the City Engineer, which serves to limit
and control stormwater runoff from a given site.
F.
Stormwater retention facilities shall be designed
so the peak rate and volume of surface runoff that occurred prior
to development is not exceeded after development. The Engineer shall
submit calculations, based on the following table, verifying that
the above criteria are met for the two-year, ten-year and fifty-year
storm. Calculations shall be based on a twenty-four-hour storm system
in accordance with United States Soil Service Technical Release No.
55 or the Soil Conservation Service National Engineering Handbook.

G.
The weighted CN (Curve Number) shall be determined
for each site for both existing and proposed conditions and the difference
shall be used to compute the volume of excess for design of stormwater
retention facilities. The volume is equal to the depth of the rainfall
excess multiplied by the area of the site.
H.
The outlet for any stormwater retention facility shall
be designed such that the discharge rate does not exceed the peak
runoff rate for conditions existing on or before the effective date
of this chapter, such that there is no adverse effect on any other
property.
I.
In the case of detention facilities utilizing porous
media for ground absorption, such as dry wells, the porous media shall
be large enough to contain the total volume of rainfall excess within
the voids. Ground absorption systems shall be used only where the
soil infiltration rate is acceptable, as determined by percolation
tests and soil borings provided by the developer. Seasonal high-ground
water shall be determined by the mottling method or other approved
methods.
J.
If a combination of different retention techniques
is used, combined volume of the systems shall be large enough to fully
contain the total volume of rainfall excess.
K.
Stormwater retention facilities shall be maintained
regularly by the owner to ensure continual functioning of the systems
at design capacity and to prevent the health hazards associated with
debris buildup and stagnant water.
L.
As-built plans [two sets] shall be submitted to the
city after construction. They shall reflect any revisions made in
the stormwater management plan during construction.
[Added 7-9-1992 by Ord. No. 20-1992]
A.
As used in this section, "fences" shall mean an artificially
constructed barrier of wood, masonry, stone, wire, metal or any other
manufactured material or combination of materials erected for the
enclosure of land and/or dividing one piece of land from another.
B.
No fences shall be erected within the municipality
without the owner of the premises or his representative obtaining
a permit from the Construction Official of the city.
C.
The application shall be on such form as is prepared
by the Construction Official and shall include the following information:
(1)
The owner and address of the premises where
the fence is to be erected.
(2)
The name and address of the company or person
installing the fence.
(3)
A sketch or plan of the fence.
(4)
A plot plan or survey of the premises in question,
which shall show streets abutting at the nearest intersection and
shall indicate the location of structures within 10 feet of the fence.
D.
Any deed restrictions affecting the property on which
the fence is to be erected or constructed shall not be superseded
by this section.
E.
All fences shall be of quality materials and installed
in a good workmanlike manner. All fences shall be maintained by the
owner.
F.
Exemptions. The following fences shall be exempt from
the requirements of this section, relative to permit, fees, construction
or materials: fences accessory to any public facility, park, playground
or school.
G.
Regulations for fences in residential zones, unless
otherwise specified within the zone district regulations, shall be
the following:
(1)
Fences shall be no closer than one foot to the
city right-of-way.
(2)
Fences not exceeding 48 inches in height above
ground level may be erected between the city right-of-way and the
building line setback (front yard). Front yard fences shall be of
a nonsolid construction which includes a minimum visibility of 50%.
No chain-link fences shall be allowed in front yards.
[Amended 5-23-1996 by Ord. No. 8-1996; 4-9-2009 by Ord. No.
3-2009]
(3)
Fences not exceeding six feet in height above
the ground level may be erected between the front building line to
the side property lines and to the rear of the property (rear yard).
(4)
Fences on corner properties shall not be constructed
of materials that would block the view of vehicular traffic at the
intersection.
(5)
Barbed-wire fences on any common property line
with another dwelling or public right-of-way are prohibited.
I.
Upon discovery of an alleged violation of this section,
the Construction Official shall serve written notice, either by personal
service or certified mail, return receipt request, upon the owner
of the fence and/or owner or lessee of the property where the fence
is located, ordering the fence to be brought into conformity with
provisions of this section, or its removal, within 30 days of the
date of said notice. The notice shall include notification that if
the fence is not brought into conformity or removed within such time,
a summons and/or complaint will be issued by the Construction Official.
