No person in control of private property, except a residential
lot with one single-family house, shall authorize the repaving, repairing
(excluding the repair of individual potholes), resurfacing (including
top coating or chip sealing with asphalt emulsion or a thin base of
hot-mixed asphalt), reconstructing or altering of any surface that
is in direct contact with an existing storm drain inlet on that property,
unless the storm drain inlet either:
A. Already meets the design standard below to control the passage of
solid and floatable materials; or
B. Is retrofitted or replaced to meet the standard in §
113-411 below prior to the completion of the project.
Storm drain inlets identified in §
113-410 above shall comply with the following standards to control the passage of solid and floatable materials through storm drain inlets. For the purposes of this section, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to these standards, see Subsection C below.
A. Grates.
(1)
Design engineers shall use either of the following grates whenever
they use a grate in pavement or another ground surface to collect
stormwater from that surface into a storm drain or surface water body
under that grate:
(a)
The New Jersey Department of Transportation (NJDOT) bicycle-safe
grate, which is described in Chapter 2.4 of the NJDOT Bicycle Compatible
Roadways and Bikeways Planning and Design Guidelines (April 1996);
or
(b)
A different grate, if each individual clear space in that grate
has an area of no more than 7.0 square inches or is no greater than
0.5 inch across the smallest dimension.
(2)
Examples of grates subject to this standard include grates in
grate inlets, the grate portion (non-curb-opening portion) of combination
inlets, grates on storm sewer manholes, ditch grates, trench grates,
and grates of spacer bars in slotted drains. Examples of ground surfaces
include surfaces of roads (including bridges), driveways, parking
areas, bikeways, plazas, sidewalks, lawns, fields, open channels,
and stormwater basin floors.
B. Whenever design engineers use a curb-opening inlet, the clear space
in that curb opening, or each individual clear space, if the curb
opening has two or more clear spaces, shall have an area of no more
than 7.0 square inches or be no greater than 2.0 inches across the
smallest dimension.
C. These standards do not apply:
(1)
Where the Municipal Engineer agrees that these standards would
cause inadequate hydraulic performance that could not practicably
be overcome by using additional or larger storm drain inlets that
meet these standards;
(2)
Where flows are conveyed through any device (e.g., end-of-pipe
netting facility, manufactured treatment device, or catch basin hood)
that is designed, at a minimum, to prevent the delivery of all solid
and floatable materials that could not pass through one of the following:
(a)
A rectangular space 4 5/8 inches long and 1 1/2 inches
wide (this option does not apply for outfall netting facilities);
or
(b)
A bar screen having a bar spacing of 0.5 inch.
(3)
Where flows are conveyed through a trash rack that has parallel
bars with one-inch spacing between the bars; or
(4)
Where the New Jersey Department of Environmental Protection
determines, pursuant to the New Jersey Register of Historic Places
Rules at N.J.A.C. 7:4-7.2(c), that action to meet these standards
is an undertaking that constitutes an encroachment or will damage
or destroy the New Jersey Register-listed historic property.
Prior to the commencement of any repaving, repairing, reconstruction,
resurfacing or similar alterations of facilities on private property,
except a residential lot with one single-family house, approval shall
be obtained from the Zoning Officer and the Superintendent of the
Department of Public Works (DPW), or his designee, as needed to verify
the installation of the appropriate storm inlet retrofit devices.
This Part 10 shall be enforced by the Zoning Officer and the
Superintendent of the DPW, or his designee, of Chester Township.
Any person who is found to be in violation of the provisions
of this Part 10 shall be subject to a fine not to exceed $1,250 for
each storm drain inlet that is not retrofitted to meet the design
standard.
Each section, subsection, sentence, clause and phrase of this Part
10 is declared to be an independent section, subsection, sentence, clause and phrase, and the finding or holding of any such portion of this Part
10 to be unconstitutional, void, or ineffective, for any cause or reason, shall not affect any other portion of this Part
10.
