of agricultural development that is in conformance with a farm plan
approved by the Natural Resource Conservation Science Office and signed
by the Hunterdon County Soil Conservation District, shall be subject
to the standards contained herein.
[Amended 6-17-2002 by Ord. No. 15-2002]
The Planning Board and Zoning Board of Adjustment
shall have the power to waive any of the requirements or details specified
in this section. The applicant shall submit a letter to the Board
indicating the items for which the waivers are requested with an explanation
for the waiver request. The Board shall evaluate each waiver request
individually and may grant or deny any such waiver request.
Bikeways and paths may be required at the approving
authority's discretion, depending on the development's location in
relation to schools, recreation area, shopping facilities and existing
and proposed paths and bikeways. Bicycle traffic shall be separated
from motor vehicle and pedestrian traffic as much as possible.
Within any zone in which the nonresidential
use submitted for subdivision or site plan approval abuts a residential
zone or residential use, the following buffer area and landscaping
requirements shall apply:
A. The minimum width of the buffer shall be as designated in Articles
IV and
V or if not designated, as in the case of a nonpermitted use in the residential zone, a minimum fifty-foot buffer, or as approved by the Board, shall be provided. Buffer area shall be contiguous with residential property lines and shall be of uniform width. If the buffer is less than 20 feet wide, the applicant may be required to erect a six-foot-high stockade fence within the buffer area parallel to the lot line of the abutting residential lot and set back a distance appropriate for the landscaping treatment in the buffer area.
[Amended 4-15-2002 by Ord. No. 9-2002]
B. Requirements for planting in the buffer area.
(1) A solid and continuous landscaped screen shall be
planted and maintained to conceal parking and loading areas, eliminate
the glare of vehicle lights throughout the year and camouflage buildings
from abutting residential areas. The landscape screen shall consist
of evergreen trees, such as hemlock, Douglas fir, Norway spruce, etc.
Trees shall be planted in a zigzag pattern and not more than six feet
apart, except where otherwise authorized by the approving authority.
Evergreen trees shall not be less than five feet high when planted,
and the lowest branches shall be not more than one foot above the
ground. In the event the existing evergreen trees do not cover the
required area, said landscaping screen shall be supplemented with
evergreen shrubbery. The entire buffer area shall be planted in accordance
with these provisions.
[Amended 4-15-2002 by Ord. No. 9-2002]
(2) In addition to the landscaped screen, canopy trees, such as sugar maples, scarlet oaks, pin oaks, willow oaks, Norway maples, sweet gum and ash, and as listed in §
148-66, shall be planted by the applicant at a distance of not more than 40 feet from each other.
(3) The height of the landscaped screen shall be measured
in relation to the elevation of the edge of the parking and loading
area. Where the landscaped screen is lower than the elevation of the
parking or loading area, either the required height of the screen
shall be increased equal to the difference in elevation or the parking
or loading area shall be moved to allow the plantings to be located
in an area with a similar elevation as the parking or loading area.
(4) If the buffer area includes existing growth of evergreen
and deciduous trees and shrubbery but not enough to provide a suitable
screen as required above, existing trees and shrubbery may remain
and shall be supplemented by additional evergreen plantings to provide
the required landscape screen.
[Amended 6-17-2002 by Ord. No. 15-2002; 10-7-2002 by Ord. No. 40-2002; 4-18-2007 by Ord. No. 11-2007; 10-4-2021 by Ord. No. 33-2021; 5-6-2024 by Ord. No. 04-2024]
A. Policy statement. Flood control, groundwater recharge, and pollutant
reduction shall be achieved through the use of stormwater management
measures, including green infrastructure, Best Management Practices
(GI BMPs), and nonstructural stormwater management strategies. GI
BMPs and low impact development (LID) should be utilized to meet the
goal of maintaining natural hydrology to reduce stormwater runoff
volume, reduce erosion, encourage infiltration, and groundwater recharge,
and reduce pollution. GI BMPs and LID should be developed based upon
physical site conditions and the origin, nature, and anticipated quantity,
or amount, of potential pollutants. Multiple stormwater management
BMPs may be necessary to achieve the established performance standards
for water quality, quantity, and groundwater recharge.
B. Purpose. The purpose of this ordinance is to establish minimum stormwater management requirements and controls for "major development, minor development and redevelopment," as defined below in §
148-65.1.
C. Applicability.
(1) This ordinance shall be applicable to the following major and minor
developments:
(a)

(2) This ordinance shall also be applicable to all major and minor developments
undertaken by Readington Township.
(3) An application required by ordinance pursuant to Subsection
C(1) above that has been submitted prior to May 6, 2024, shall be subject to the stormwater management requirements in effect on May 5, 2024.
(4) An application required by ordinance for approval pursuant to Subsection
C(1) above that has been submitted on or after March 2, 2021, but prior to May 6, 2024, shall be subject to the stormwater management requirements in effect on May 5, 2024.
(5) Notwithstanding any rule to the contrary, a major development for
any public roadway or railroad project conducted by a public transportation
entity that has determined a preferred alternative or reached an equivalent
milestone before July 17, 2023, shall be subject to the stormwater
management requirements in effect prior to July 17, 2023.
D. Compatibility with other permit and ordinance requirements.
(1) Development approvals issued pursuant to this ordinance are to be
considered an integral part of development approvals and do not relieve
the applicant of the responsibility to secure required permits or
approvals for activities regulated by any other applicable code, rule,
act, or ordinance. In their interpretation and application, the provisions
of this ordinance shall be held to be the minimum requirements for
the promotion of the public health, safety, and general welfare.
(2) This ordinance is not intended to interfere with, abrogate, or annul
any other ordinances, rule or regulation, statute, or other provision
of law except that, where any provision of this ordinance imposes
restrictions different from those imposed by any other ordinance,
rule or regulation, or other provision of law, the more restrictive
provisions or higher standards shall control.

G. An alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate may be used if the design engineer demonstrates the capability of the proposed alternative stormwater management measure and/or the validity of the alternative rate or method to the municipality. A copy of any approved alternative stormwater management measure, alternative removal rate, and/or alternative method to calculate the removal rate shall be provided to the Department in accordance with §
148-65.5B. Alternative stormwater management measures may be used to satisfy the requirements at §
148-65.3O only if the measures meet the definition of green infrastructure at §
148-65.1. Alternative stormwater management measures that function in a similar manner to a BMP listed at §
148-65.3O(2) are subject to the contributory drainage area limitation specified at §
148-65.3O(2) for that similarly functioning BMP. Alternative stormwater management measures approved in accordance with this subsection that do not function in a similar manner to any BMP listed at §
148-65.3O(2) shall have a contributory drainage area less than or equal to 2.5 acres, except for alternative stormwater management measures that function similarly to cisterns, grass swales, green roofs, standard constructed wetlands, vegetative filter strips, and wet ponds, which are not subject to a contributory drainage area limitation. Alternative measures that function similarly to standard constructed wetlands or wet ponds shall not be used for compliance with the stormwater runoff quality standard unless a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with §
148-65.3D is granted from §
148-65.3O.
H. Whenever the stormwater management design includes one or more BMPs
that will infiltrate stormwater into subsoil, the design engineer
shall assess the hydraulic impact on the groundwater table and design
the site, so as to avoid adverse hydraulic impacts. Potential adverse
hydraulic impacts include, but are not limited to, exacerbating a
naturally or seasonally high-water table, so as to cause surficial
ponding, flooding of basements, or interference with the proper operation
of subsurface sewage disposal systems or other subsurface structures
within the zone of influence of the groundwater mound, or interference
with the proper functioning of the stormwater management measure itself.
I. Design standards for stormwater management measures are as follows:
(1)
Stormwater management measures shall be designed to take into
account the existing site conditions, including, but not limited to,
environmentally critical areas; wetlands; flood-prone areas; slopes;
depth to seasonal high-water table; soil type, permeability, and texture;
drainage area and drainage patterns; and the presence of solution-prone
carbonate rocks (limestone);
(2)
Stormwater management measures shall be designed to minimize maintenance, facilitate maintenance and repairs, and ensure proper functioning. Trash racks shall be installed at the intake to the outlet structure, as appropriate, and shall have parallel bars with one inch spacing between the bars to the elevation of the water quality design storm. For elevations higher than the water quality design storm, the parallel bars at the outlet structure shall be spaced no greater than one-third the width of the diameter of the orifice or one-third the width of the weir, with a minimum spacing between bars of one inch and a maximum spacing between bars of six inches. In addition, the design of trash racks must comply with the requirements of §
148-65.7C;
(3)
Stormwater management measures shall be designed, constructed,
and installed to be strong, durable, and corrosion resistant. Measures
that are consistent with the relevant portions of the Residential
Site Improvement Standards at N.J.A.C. 5:21-7.3, 7.4, and 7.5 shall
be deemed to meet this requirement;
(4)
Stormwater management BMPs shall be designed to meet the minimum safety standards for stormwater management BMPs at §
148-65.7; and
(5)
The size of the orifice at the intake to the outlet from the
stormwater management BMP shall be a minimum of 2 1/2 inches
in diameter.
J. Manufactured treatment devices may be used to meet the requirements of this subchapter, provided the pollutant removal rates are verified by the New Jersey Corporation for Advanced Technology and certified by the Department. Manufactured treatment devices that do not meet the definition of green infrastructure at §
148-65.1 may be used only under the circumstances described at §
148-65.3O(4).
K. Any application for a new agricultural development that meets the definition of major development at §
148-65.1 shall be submitted to the Soil Conservation District for review and approval in accordance with the requirements at §
148-65.3O,
P,
Q and
R and any applicable Soil Conservation District guidelines for stormwater runoff quantity and erosion control. For purposes of this subsection, "agricultural development" means land uses normally associated with the production of food, fiber, and livestock for sale. Such uses do not include the development of land for the processing or sale of food and the manufacture of agriculturally related products.
L. If there is more than one drainage area, the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at §
148-65.3P,
Q and
R shall be met in each drainage area, unless the runoff from the drainage areas converge onsite and no adverse environmental impact would occur as a result of compliance with any one or more of the individual standards being determined utilizing a weighted average of the results achieved for that individual standard across the affected drainage areas.
M. Any stormwater management measure authorized under the municipal stormwater management plan or ordinance shall be reflected in a deed notice recorded in the Office of the County Clerk, Hunterdon County. A form of deed notice shall be submitted to the municipality for approval prior to filing. The deed notice shall contain a description of the stormwater management measure(s) used to meet the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at §
148-65.3O,
P,
Q and
R and shall identify the location of the stormwater management measure(s) in NAD 1983 State Plane New Jersey FIPS 2900 US Feet or Latitude and Longitude in decimal degrees. The deed notice shall also reference the maintenance plan required to be recorded upon the deed pursuant to §
148-65.9B(5). Prior to the commencement of construction, proof that the above required deed notice has been filed shall be submitted to the municipality. Proof that the required information has been recorded on the deed shall be in the form of either a copy of the complete recorded document or a receipt from the clerk or other proof of recordation provided by the recording office. However, if the initial proof provided to the municipality is not a copy of the complete recorded document, a copy of the complete recorded document shall be provided to the municipality within 180 calendar days of the authorization granted by the municipality.
N. A stormwater management measure approved under the municipal stormwater management plan or ordinance may be altered or replaced with the approval of the municipality if the municipality determines that the proposed alteration or replacement meets the design and performance standards pursuant to §
148-65.3 of this ordinance and provides the same level of stormwater management as the previously approved stormwater management measure that is being altered or replaced. If an alteration or replacement is approved, a revised deed notice shall be submitted to the municipality for approval and subsequently recorded with the Office of the County Clerk, Hunterdon County and shall contain a description and location of the stormwater management measure, as well as reference to the maintenance plan, in accordance with Subsection
M above. Prior to the commencement of construction, proof that the above required deed notice has been filed shall be submitted to the municipality in accordance with Subsection
M above.
O. Green infrastructure standards.
(1)
This subsection specifies the types of green infrastructure
BMPs that may be used to satisfy the groundwater recharge, stormwater
runoff quality, and stormwater runoff quantity standards.
(2)
To satisfy the groundwater recharge and stormwater runoff quality standards at §
148-65.3P and
Q, the design engineer shall utilize green infrastructure BMPs identified in Table 1 at §
148-65.3F. and/or an alternative stormwater management measure approved in accordance with §
148-65.3G. The following green infrastructure BMPs are subject to the following maximum contributory drainage area limitations:
Best Management Practice
|
Maximum Contributory Drainage Area
|
---|

|
(3)
To satisfy the stormwater runoff quantity standards at §
148-65.3R, the design engineer shall utilize BMPs from Table 1 or from Table 2 and/or an alternative stormwater management measure approved in accordance with §
148-65.3G.
(4)
If a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with §
148-65.3D is granted from the requirements of this subsection, then BMPs from Table 1, 2, or 3, and/or an alternative stormwater management measure approved in accordance with §
148-65.3G may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at §
148-65.3P,
Q and
R.
(5)
For separate or combined storm sewer improvement projects, such as sewer separation, undertaken by a government agency or public utility (for example, a sewerage company), the requirements of this subsection shall only apply to areas owned in fee simple by the government agency or utility, and areas within a right-of-way or easement held or controlled by the government agency or utility; the entity shall not be required to obtain additional property or property rights to fully satisfy the requirements of this subsection. Regardless of the amount of area of a separate or combined storm sewer improvement project subject to the green infrastructure requirements of this subsection, each project shall fully comply with the applicable groundwater recharge, stormwater runoff quality control, and stormwater runoff quantity standards at §
148-65.3P,
Q and
R, unless the project is granted a waiver from strict compliance in accordance with §
148-65.3D.
P. Groundwater recharge standards.
(1)
This subsection contains the minimum design and performance
standards for groundwater recharge as follows:
(2)
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at §
148-65.4, either:
(a)
Demonstrate through hydrologic and hydraulic analysis that the
site and its stormwater management measures maintain 100% of the average
annual pre-construction groundwater recharge volume for the site;
or
(b)
Demonstrate through hydrologic and hydraulic analysis that the
increase of stormwater runoff volume from pre-construction to post-construction
for the two-year storm is infiltrated.
(3)
This groundwater recharge requirement does not apply to projects within the "urban redevelopment area," or to projects subject to Subsection
P(4) below.
(4)
The following types of stormwater shall not be recharged:
(a)
Stormwater from areas of high pollutant loading. High pollutant
loading areas are areas in industrial and commercial developments
where solvents and/or petroleum products are loaded/unloaded, stored,
or applied, areas where pesticides are loaded/unloaded or stored;
areas where hazardous materials are expected to be present in greater
than "reportable quantities" as defined by the United States Environmental
Protection Agency (EPA) at 40 CFR 302.4; areas where recharge would
be inconsistent with Department approved remedial action work plan
or landfill closure plan and areas with high risks for spills of toxic
materials, such as gas stations and vehicle maintenance facilities;
and
(b)
Industrial stormwater exposed to "source material." "Source
material" means any material(s) or machinery, located at an industrial
facility, that is directly or indirectly related to process, manufacturing,
or other industrial activities, which could be a source of pollutants
in any industrial stormwater discharge to groundwater. Source materials
include, but are not limited to, raw materials; intermediate products;
final products; waste materials; by-products; industrial machinery
and fuels, and lubricants, solvents, and detergents that are related
to process, manufacturing, or other industrial activities that are
exposed to stormwater.
Q. Stormwater runoff quality standards.
(1)
This subsection contains the minimum design and performance
standards to control stormwater runoff quality impacts of major development.
Stormwater runoff quality standards are applicable when the major
development results in an increase of one-quarter acre or more of
regulated motor vehicle surface.
(2)
Stormwater management measures shall be designed to reduce the
post-construction load of total suspended solids (TSS) in stormwater
runoff generated from the water quality design storm as follows:
(a)
Ninety percent TSS removal of the anticipated load, expressed
as an annual average shall be achieved for the stormwater runoff from
the net increase of motor vehicle surface.
(b)
If the surface is considered regulated motor vehicle surface
because the water quality treatment for an area of motor vehicle surface
that is currently receiving water quality treatment either by vegetation
or soil, by an existing stormwater management measure, or by treatment
at a wastewater treatment plant is to be modified or removed, the
project shall maintain or increase the existing TSS removal of the
anticipated load expressed as an annual average.
(3)
The requirement to reduce TSS does not apply to any stormwater runoff in a discharge regulated under a numeric effluent limitation for TSS imposed under the New Jersey Pollutant Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJPDES permit from this requirement. Every major development, including any that discharge into a combined sewer system, shall comply with Subsection
Q(2) above, unless the major development is itself subject to a NJPDES permit with a numeric effluent limitation for TSS or the NJPDES permit to which the major development is subject exempts the development from a numeric effluent limitation for TSS.
(4)
The water quality design storm is 1.25 inches of rainfall in
two hours. Water quality calculations shall take into account the
distribution of rain from the water quality design storm, as reflected
in Table 4, below. The calculation of the volume of runoff may take
into account the implementation of stormwater management measures.

If more than one BMP in series is necessary to achieve the required
90% TSS reduction for a site, the applicant shall utilize the following
formula to calculate TSS reduction:
R = A + B - (A x B)/100
|
Where:
|
R
|
=
|
total TSS percent load removal from application of both BMPs
|
A
|
=
|
the TSS percent removal rate applicable to the first BMP
|
B
|
=
|
the TSS percent removal rate applicable to the second BMP
|
(6)
Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the post-construction nutrient load of the anticipated load from the developed site in stormwater runoff generated from the water quality design storm. In achieving reduction of nutrients to the maximum extent feasible, the design of the site shall include green infrastructure BMPs that optimize nutrient removal while still achieving the performance standards in §
148-65.3P,
Q and
R. Total phosphorus (TP) and total nitrogen (TN) should be removed as low as practically possible.
(7)
In accordance with the definition of FW1 at N.J.A.C. 7:9B-1.4,
stormwater management measures shall be designed to prevent any increase
in stormwater runoff to waters classified as FW1.
(8)
The Flood Hazard Area Control Act Rules at N.J.A.C. 7:13-4.1(c)1
establish 300-foot riparian zones along Category One waters, as designated
in the Surface Water Quality Standards at N.J.A.C. 7:9B, and certain
upstream tributaries to Category One waters. A person shall not undertake
a major development that is located within or discharges into a 300-foot
riparian zone without prior authorization from the Department under
N.J.A.C. 7:13.
(9)
Pursuant to the Flood Hazard Area Control Act Rules at N.J.A.C.
7:13-11.2(j)3.i, runoff from the water quality design storm that is
discharged within a 300-foot riparian zone shall be treated in accordance
with this subsection to reduce the post-construction load of total
suspended solids by 95% of the anticipated load from the developed
site, expressed as an annual average.
(10)
The stormwater runoff quality standards do not apply to the
construction of one individual single-family dwelling, provided that
it is not part of a larger development or subdivision that has received
preliminary or final site plan approval prior to December 3, 2018,
and that the motor vehicle surfaces are made of permeable material(s)
such as gravel, dirt, and/or shells.
R. Stormwater runoff quantity standards.
(1)
This subsection contains the minimum design and performance
standards to control stormwater runoff quantity impacts of major development.
(2)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at §
148-65.4, complete one of the following:
(a)
Demonstrate through hydrologic and hydraulic analysis that for stormwater leaving the site, post-construction runoff hydrographs for the current and projected two-, ten-, and 100-year storm events, as defined and determined in §
148-65.4C and
D, respectively, of this ordinance do not exceed, at any point in time, the pre-construction runoff hydrographs for the same storm events;
(b)
Demonstrate through hydrologic and hydraulic analysis that there is no increase, as compared to the pre-construction condition, in the peak runoff rates of stormwater leaving the site for the current and projected two-, ten-, and 100-year storm events, as defined and determined pursuant to §
148-65.4C and
D, respectively, of this ordinance, and that the increased volume or change in timing of stormwater runoff will not increase flood damage at or downstream of the site. This analysis shall include the analysis of impacts of existing land uses and projected land uses assuming full development under existing zoning and land use ordinances in the drainage area;
(c)
Design stormwater management measures so that the post-construction peak runoff rates for the current and projected two-, ten- and 100-year storm events, as defined and determined in §
148-65.4C and
D, respectively, of this ordinance, are 50%, 75% and 80%, respectively, of the pre-construction peak runoff rates. The percentages apply only to the post-construction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed; or
(d)
In tidal flood hazard areas, stormwater runoff quantity analysis in accordance with Subsection
R(2)(a) through
(c) above is required unless the design engineer demonstrates through hydrologic and hydraulic analysis that the increased volume, change in timing, or increased rate of the stormwater runoff, or any combination of the three will not result in additional flood damage below the point of discharge of the major development. No analysis is required if the stormwater is discharged directly into any ocean, bay, inlet, or the reach of any watercourse between its confluence with an ocean, bay, or inlet and downstream of the first water control structure.
(3)
The stormwater runoff quantity standards shall be applied at
the site's boundary to each abutting lot, roadway, watercourse, or
receiving storm sewer system.
(4)
For minor developments for each square foot or new impervious
surface, two gallons of stormwater will be managed on site using green
infrastructure practices. Of the volume 0.78 gallons (equivalent to
the water quality design storm of 1.25 inches) must be retained on
site while the remainder may be discharged offsite from the stormwater
management measure. The green infrastructure practices such as grass
swale, green roof, pervious paving systems, small scale bioretention
basins, rain gardens, small scale infiltration basins, small scale
sand filter, vegetative strip, cistern, and drywell shall be designed
and implemented as required. The use of cisterns and drywells is allowed
only where the other listed methods cannot meet the requirements of
this subsection.

A. Stormwater runoff shall be calculated in accordance with the following:
(1)
The design engineer shall calculate runoff using one of the
following methods:
(a) The USDA Natural Resources Conservation Service (NRCS) methodology,
including the NRCS Runoff Equation and Dimensionless Unit Hydrograph,
as described in Chapters 7, 9, 10, 15 and 16 Part 630, Hydrology National
Engineering Handbook, incorporated herein by reference as amended
and supplemented. This methodology is additionally described in Technical
Release 55
Urban Hydrology for Small Watersheds (TR-55), dated June
1986, incorporated herein by reference as amended and supplemented.
Information regarding the methodology is available from the Natural
Resources Conservation Service website at: https://directives.sc.egov.usda.gov/viewerFS.aspx?hid=21422,
or at United States Department of Agriculture Natural Resources Conservation
Service, 220 Davison Avenue, Somerset, New Jersey 08873.
(2)
For the purpose of calculating curve numbers and groundwater
recharge, there is a presumption that the pre-construction condition
of a site or portion thereof is a wooded land use with good hydrologic
condition. The term "curve number" applies to both the NRCS methodology
above at § 148-65.4A(1)(a) A curve number or a groundwater
recharge land cover for an existing condition may be used on all or
a portion of the site if the design engineer verifies that the hydrologic
condition has existed on the site or portion of the site for at least
five years without interruption prior to the time of application.
If more than one land cover has existed on the site during the five
years immediately prior to the time of application, the land cover
with the lowest runoff potential shall be used for the computations.
In addition, there is the presumption that the site is in good hydrologic
condition (if the land use type is pasture, lawn, or park), with good
cover (if the land use type is woods), or with good hydrologic condition
and conservation treatment (if the land use type is cultivation).
(3)
In computing pre-construction stormwater runoff, the design
engineer shall account for all significant land features and structures,
such as ponds, wetlands, depressions, hedgerows, or culverts, that
may reduce pre-construction stormwater runoff rates and volumes.
(4)
If the invert of the outlet structure of a stormwater management
measure is below the flood hazard design flood elevation as defined
at N.J.A.C. 7:13, the design engineer shall take into account the
effects of tailwater in the design of structural stormwater management
measures.
B. Groundwater recharge may be calculated in accordance with the following:
(1)
The New Jersey Geological Survey Report GSR-32, A Method for
Evaluating Groundwater-Recharge Areas in New Jersey, incorporated
herein by reference as amended and supplemented. Information regarding
the methodology is available from the New Jersey Stormwater Best Management
Practices Manual; at the New Jersey Geological Survey website at:
https://www.nj.gov/dep/njgs/pricelst/gsreport/gsr32.pdf or at New
Jersey Geological and Water Survey, 29 Arctic Parkway, PO Box 420
Mail Code 29-01, Trenton, New Jersey 08625-0420.
C. The precipitation depths of the current two-, ten-, and 100-year storm events shall be determined by multiplying the values determined in accordance with Subsection
C(1) and
(2) below:
(1)
The applicant shall utilize the National Oceanographic and Atmospheric
Administration (NOAA), National Weather Service's Atlas 14 Point Precipitation
Frequency Estimates: NJ, in accordance with the location(s) of the
drainage area(s) of the site. This data is available at: https://hdsc.nws.noaa.gov/hdsc/pfds/pfds_map_cont.html?bkmrk=nj;
and
(2)
The applicant shall utilize Table 5: Current Precipitation Adjustment
Factors below, which sets forth the applicable multiplier for the
drainage area(s) of the site, in accordance with the county or counties
where the drainage area(s) of the site is located. Where the major
development lies in more than one county, the precipitation values
shall be adjusted according to the percentage of the drainage area
in each county. Alternately, separate rainfall totals can be developed
for each county using the values in the table below.

(2)
The maintenance plan shall contain specific preventative maintenance
tasks and schedules; cost estimates, including estimated cost of sediment,
debris, or trash removal; and the name, address, and telephone number
of the person or persons responsible for preventative and corrective
maintenance (including replacement). The plan shall contain information
on BMP location, design, ownership, maintenance tasks and frequencies,
and other details as specified in Chapter 8 of the NJ BMP Manual,
as well as the tasks specific to the type of BMP, as described in
the applicable chapter containing design specifics.
(3)
If the maintenance plan identifies a person other than the property
owner (for example, a developer, a public agency, or homeowners' association)
as having the responsibility for maintenance, the plan shall include
documentation of such person's or entity's agreement to assume this
responsibility, or of the owner's obligation to dedicate a stormwater
management facility to such person under an applicable ordinance or
regulation.
(4)
Responsibility for maintenance shall not be assigned or transferred
to the owner or tenant of an individual property in a residential
development or project unless such owner or tenant owns or leases
the entire residential development or project. The individual property
owner may be assigned incidental tasks, such as weeding of a green
infrastructure BMP, provided the individual agrees to assume these
tasks; however, the individual cannot be legally responsible for all
of the maintenance required.
(5)
If the party responsible for maintenance identified under §
148-65.9B(3) above is not a public agency, the maintenance plan and any future revisions based on §
148-65.9B(7) below shall be recorded upon the deed of record for each property on which the maintenance described in the maintenance plan must be undertaken.
(6)
Preventative and corrective maintenance shall be performed to
maintain the functional parameters (storage volume, infiltration rates,
inflow/outflow capacity, etc.). of the stormwater management measure,
including, but not limited to, repairs or replacement to the structure;
removal of sediment, debris, or trash; restoration of eroded areas;
snow and ice removal; fence repair or replacement; restoration of
vegetation; and repair or replacement of non-vegetated linings.
(7)
The party responsible for maintenance identified under §
148-65.9B(3) above shall perform all of the following requirements:
(a)
Maintain a detailed log of all preventative and corrective maintenance
for the structural stormwater management measures incorporated into
the design of the development, including a record of all inspections
and copies of all maintenance-related work orders;
(b)
Evaluate the effectiveness of the maintenance plan at least
once per year and adjust the plan and the deed as needed; and
(c)
Retain and make available, upon request by any public entity with administrative, health, environmental, or safety authority over the site, the maintenance plan and the documentation required by §
148-65.9B(6) and
(7) above.
(8)
The requirements of §
148-65.9B(3) and
(4) do not apply to stormwater management facilities that are dedicated to and accepted by the municipality or another governmental agency, subject to all applicable municipal stormwater general permit conditions, as issued by the Department.
(9)
In the event that the stormwater management facility becomes
a danger to public safety or public health, or if it is in need of
maintenance or repair, the municipality shall so notify the responsible
person in writing. Upon receipt of that notice, the responsible person
shall have 14 days to effect maintenance and repair of the facility
in a manner that is approved by the municipal engineer or his designee.
The municipality, in its discretion, may extend the time allowed for
effecting maintenance and repair for good cause. If the responsible
person fails or refuses to perform such maintenance and repair, the
municipality or County may immediately proceed to do so and shall
bill the cost thereof to the responsible person. Nonpayment of such
bill may result in a lien on the property.
C. Nothing in this subsection shall preclude the municipality in which
the major is located from requiring the posting of a performance or

[Added 10-4-2021 by Ord.
No. 33-2021; amended 5-6-2024 by Ord. No. 04-2024]
All streets shall be provided with manholes, catch basins, pipes,
or other conveyance systems where the same may be necessary for proper
drainage. Designers should focus on the incorporation of properly
designed and distributed open, vegetated swales wherever practicable.
These systems provide a green infrastructure solution for stormwater
control and conveyance, providing both runoff volume and rate control
along with water quality benefits. These systems also provide a more
distributed, decentralized approach to managing stormwater at its
source consistent with the definition of green infrastructure.
A. The system shall include the natural drainage basin area or areas
and shall be adequate to carry off the stormwater and natural drainage
water which originates not only within the lot or tract boundaries
but also that which originates beyond the lot or tract boundaries
in their current state of development. The system shall be extended
along the full length of any road improvement. No stormwater runoff
or natural drainage water shall be so diverted as to overload existing
drainage systems to create flooding or the need for additional drainage
structures on other private properties or public lands without proper
and approved provisions being made for taking care of these conditions.
B. All materials used in the construction of storm sewers, bridges and
other drainage structures shall be in accordance with current specifications
of NJDOT for Road and Bridge Construction, as prepared by the New
Jersey Department of Transportation and any supplements, addenda and
modifications thereto unless otherwise specified by Readington Township.
Modifications or changes of these specifications may be requested
by the applicant but may be implemented only with the knowledge and
written consent of the Township following input received by the Township's
professionals.
C. Pipe sizes shall be determined by acceptable drainage design procedures,
provided that the pipe size in a surface water drainage system shall
in no instance be less than 15 inches in diameter.
D. Drainage inlets shall be located at all intersections, with inlets
on both sides of a street at intervals of not more than 300 feet or
such shorter distances as required to prevent the flow of surface
water from exceeding six cubic feet per second at the drainage inlet.
Access manholes shall be placed at maximum 400-foot intervals throughout
the system and at pipe junctions where there are no drainage inlets.
E. Surface water in all paved areas shall be collected at intervals
so that it will not obstruct the flow of vehicular or pedestrian traffic
and will not create ponding in paved areas. Gutters or paved swales
shall be used whenever, in the judgment of the Township Engineer,
they are necessary to avoid erosion.
F. Lots shall be graded away from the building(s) at a minimum 2% grade
in order to secure proper drainage. Additionally, drainage shall be
provided in a manner which will prevent the collection of stormwater
in pools or other unauthorized concentrations of flow and water shall
not flow across adjacent property lines at greater than predevelopment
rates.
G. Approval of drainage structures shall be obtained from the appropriate
municipal, county, state and federal agencies and office. Where required,
each applicant shall make application to NJDEP, the Hunterdon County
Engineering Department and the Township Engineer. Final approval shall
not be effective until letters of approval from the proper governmental
authorities shall be furnished to the Secretary of the Planning Board
or the Secretary of the Zoning Board of Adjustment, as the case may
be, with a copy of each letter forwarded to the Township Engineer.
H. When required by the Township and as indicated on an approved development
plan, a drainage right-of-way easement shall be provided to the Township
where a tract or lot is traversed by a watercourse, surface or underground
drainageway or drainage system, channel, or stream. Said easement
and right-of-way shall include provisions assuring the following:
preservation of the channel of the watercourse; prohibition of alteration
of the contour, topography or composition of the land within the easement
and right-of-way; prohibition of construction within the boundaries
of the easement and right-of-way which will obstruct or interfere
with the natural flow of the watercourse; and reservation to the (Public
Works Department) Township of a right of entry (but not the obligation)
for the purpose of maintaining the natural flow or drainage of the
watercourse, of maintaining any and all structures related to the
exercise of the easement and right-of-way and of installing and maintaining
a storm or sanitary sewer system or other public utility. The drainage
right-of-way easement shall conform substantially with the thread

Buildings shall show a harmony of design with their surroundings,
and any shapes, signs and lighting, colors and other characteristics
which cause a building to call excessive attention and create disharmony
shall be avoided.
(2)
All buildings shall be related harmoniously
to the natural features of the site and to existing buildings and
other structures in the vicinity that have a visual relationship to
the proposed building or buildings. The achievement of such relationship
may include the enclosure of space in conjunction with other existing/proposed
buildings or the creation of focal points. With respect to public
spaces, building design/orientation may have to be adjusted in order
to maintain a positive spatial relationship or to preserve visual
access to community focal points, either natural or man-made.
(3)
The selection of building design elements, for
example in the use of materials, fenestration, color, texture, and
other design considerations, should ensure that such treatment is
generally consistent with traditional and vernacular 18th- and 19th-
and early 20th-century architectural styles.
(4)
Building additions and renovations should be
designed to reflect the existing building in terms of scale, materials,
fenestration and color.
(5)
Appearance of the side and rear elevations of
buildings shall receive architectural treatments comparable to that
of any proposed front facade if said elevations are generally within
public view.
(6)
Buildings should, where appropriate, strengthen
the particular design features of their locale by, for example, framing
a view corridor, enclosing an open space area, or continuing a particular
design feature or statement. Such construction should complement the
existing historic building designs in the Village.
C. Building massing and scale.
(1)
Long, horizontal facades should be broken down
into segments having vertical orientation, and tall vertically oriented
facades shall be broken down into horizontal components through use
of appropriate design features.
(2)
Buildings with expansive blank walls are prohibited.
(3)
Buildings should be designed so that facades
are the prominent architectural feature and the roofs are visually
less dominant in the total design. Architecturally accurate roof styles
shall be consistent with the proximal historic context.
(4)
A pedestrian scale should be achieved at ground
level and along street frontages and entryways through the use of
such scale elements as windows, doors, columns, plazas, awnings, canopies,
and site furnishings.
(5)
In new infill construction, the alignments of
proposed facades shall be consistent with the existing setback of
nearby buildings to the extent permitted by this section.
D. Facade treatment.
(1)
Multitenant buildings shall provide uniform
storefronts, doorways, windows, awnings and other design features
for all ground floor tenants. Upper floors of said buildings shall
at a minimum be coordinated with the ground floor through common materials
and colors. Storefronts should include display windows with a sill
height not less than two feet from grade.
(2)
Buildings should use windows of similar sizes
and shapes or incorporate other facade elements that establish the
same pattern of other buildings in its context.
(3)
Dominant zones and horizontal lines that establish
those zones should be included in the design. Such lines include the
tops of display windows, sign fascias, cornices and belt courses.
(4)
Design elements that carry through a block such
as storefront patterns, window spacing, entrances, canopies or awnings,
etc., should be incorporated into new or renovated facades.
(5)
Exterior mounted mechanical and electrical equipment
shall be completely screened from public view with opaque architectural
elements.
(6)
Facade renovations should be consistent with
the original architectural style of the building. Original details
should be retained; when it becomes necessary to introduce new features,
they should harmonize with existing features. If windows and doors
must be replaced, new materials that match the original design should
be used, wherever possible.
(7)
The use of creative lighting schemes to highlight
building facades and related areas of a site shall be encouraged,
except that any such nonresidential lighting shall be shut off by
10:00 p.m. or 1/2 hour after the closing of such nonresidential use.
E. Building materials, colors and texture.
(1)
On existing buildings, original materials shall
be retained wherever possible, and the repair and restoration of existing
materials deemed of architectural value shall be strongly encouraged.
(2)
Where appropriate, building renovations shall
incorporate elements of the original structure into the renovation
design.
(3)
The use of brick, stone, clapboard, shakes and
other facade materials of a traditional and vernacular nature shall
be strongly encouraged.
(4)
Metal panels and mirrored glass surfaces are
prohibited on all buildings.
(5)
The painting of buildings in bold colors, patterns,
checks or stripes is discouraged.
(6)
The use of colors generally associated with
traditional building design shall be encouraged on all buildings.
Accent or complementary colors which harmonize with the main facade
colors shall be permitted for trim, awning and other building details.
Acceptable paint colors from the relevant periods can be found within
the following reference, which is maintained for review in the Planning
Office:
(a)
Paint in America, the Colors of Historic Buildings
(Moss, Roger, John Wiley & Sons, Inc., 1994).
F. Other requirements.
(1)
Awnings shall be encouraged on nonresidential
buildings. All awnings shall be constructed and installed so that
the frame and fabric of the awning is integrated into the overall
building design. No awning shall extend beyond a dimension appropriate
with the size and scale of the subject building, and no awning shall
be less than eight feet above the ground. Awnings which project into
any roadway, driveway, parking or loading area are prohibited. Awnings
shall not be placed so as to conceal or disfigure an architectural
feature or detail. Awning materials shall be limited to cloth, canvas
and similar materials; metal and aluminum awnings are prohibited.
Plastic, internally illuminated awnings are prohibited. Awnings may
be solid or striped, but colors shall be coordinated with the facade
colors.
