Reserve access strips. No subdivision showing reserve
strips controlling access to streets shall be approved unless the
control and disposal of land comprising such strips has been placed
in the Village Council under conditions approved by the Board and
the Council.
H.
Suitability of lots for development. The Board may,
after adequate investigation, withhold approval of any lot which,
in its opinion, is not suitable for its intended use due to factors
such as, but not limited to, rock formations, surface or underground
mines, flooding, wetlands, soil conditions, presence of hazardous
materials, excessive slopes, etc.

[Amended 1-15-2003 by Ord. No. 2814; 3-8-2006 by Ord. No. 2983; 1-17-2007 by Ord. No. 3035; 11-9-2009 by Ord. No. 3223; 2-24-2021 by Ord. No. 3844]
A.
Scope and purpose.
(1)
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 the 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.
(2)
Purpose. The purpose of this section is to establish minimum stormwater management requirements and controls for major development and minor development, as defined below in Subsection B.
(3)
(4)
Compatibility with other permit and ordinance requirements.
(a)
Development approvals issued pursuant to this section 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 section shall be held to be the minimum requirements
for the promotion of the public health, safety, and general welfare.
(b)
This section 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 section
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.

known as "hydrophytic vegetation."
C.
Design and performance standards for stormwater management measures.
(1)
Stormwater management measures for major development shall be designed
to provide erosion control, groundwater recharge, stormwater runoff
quantity control, and stormwater runoff quality treatment as follows:
(a)
The minimum standards for erosion control are those established
under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39
et seq., and implementing rules at N.J.A.C. 2:90.
(b)
The minimum standards for groundwater recharge, stormwater quality,
and stormwater runoff quantity shall be met by incorporating green
infrastructure.
(2)
The standards in this section apply only to new major development
and are intended to minimize the impact of stormwater runoff on water
quality and water quantity in receiving water bodies and maintain
groundwater recharge. The standards do not apply to new major development
to the extent that alternative design and performance standards are
applicable under a regional stormwater management plan or water quality
management plan adopted in accordance with Department rules.
D.
Stormwater management requirements for major development.
(1)
The development shall incorporate a maintenance plan for the stormwater management measures incorporated into the design of a major development in accordance with Subsection J.
(2)
Stormwater management measures shall avoid adverse impacts of concentrated
flow on habitat for threatened and endangered species as documented
in the Department's Landscape Project or Natural Heritage Database
established under N.J.S.A. 13:1B-15.147 through 13:1B-15.150, particularly
Helonias bullata (swamp pink) and/or Clemmys muhlenbergi (bog turtle).
(3)
The following linear development projects are exempt from the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity requirements of Subsection D(16), (17) and (18):
(a)
The construction of an underground utility line provided that
the disturbed areas are revegetated upon completion;
(b)
The construction of an aboveground utility line provided that
the existing conditions are maintained to the maximum extent practicable;
and
(c)
The construction of a public pedestrian access, such as a sidewalk
or trail with a maximum width of 14 feet, provided that the access
is made of permeable material.
(4)
A waiver from strict compliance from the green infrastructure, groundwater recharge, stormwater runoff quality, and stormwater runoff quantity requirements of Subsection D(15), (16), (17) and (18) may be obtained for the enlargement of an existing public roadway or railroad; or the construction or enlargement of a public pedestrian access, provided that the following conditions are met:
(a)
The applicant demonstrates that there is a public need for the
project that cannot be accomplished by any other means;
(d)
The applicant demonstrates that it does not own or have other rights to areas, including the potential to obtain through condemnation lands not falling under Subsection D(4)(c) above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate the requirements of Subsection D(15), (16), (17) and (18) that were not achievable on-site.
(5)
Tables 1 through 3 below summarize the ability of stormwater best management practices identified and described in the New Jersey Stormwater Best Management Practices Manual to satisfy the green infrastructure, groundwater recharge, stormwater runoff quality and stormwater runoff quantity standards specified in Subsection D(15), (16), (17) and (18). When designed in accordance with the most current version of the New Jersey Stormwater Best Management Practices Manual, the stormwater management measures found at N.J.A.C. 7:8-5.2(f) Tables 5-1, 5-2 and 5-3 and listed below in Tables 1, 2 and 3 are presumed to be capable of providing stormwater controls for the design and performance standards as outlined in the tables below. Upon amendments of the New Jersey Stormwater Best Management Practices to reflect additions or deletions of BMPs meeting these standards, or changes in the presumed performance of BMPs designed in accordance with the New Jersey Stormwater BMP Manual, the Department shall publish in the New Jersey Registers a notice of administrative change revising the applicable table. The most current version of the BMP Manual can be found on the Department's website at https://njstormwater.org/bmp_manual2.htm.
(6)
Where the BMP tables in the NJ Stormwater Management Rule are different
due to updates or amendments with the tables in this ordinance the
BMP Tables in the Stormwater Management rule at N.J.A.C. 7:8-5.2(f)
shall take precedence.

(8)
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.
(9)
Design standards for stormwater management measures are as follows:
(a)
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);
(b)
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 1/3 the width of the diameter of the orifice or 1/3 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 Subsection H(3);
(c)
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

(e)
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.
(10)
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 Subsection B may be used only under the circumstances described at Subsection D(15)(d).
(11)
Any application for a new agricultural development that meets the definition of major development at Subsection B shall be submitted to the Soil Conservation District for review and approval in accordance with the requirements at Subsections D(15), (16), (17) and (18) 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.
(12)
If there is more than one drainage area, the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsections D(16), (17) and (18) shall be met in each drainage area, unless the runoff from the drainage areas converge on-site 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.
(13)
Any stormwater management measure authorized under the municipal stormwater management plan or ordinance shall be reflected in a deed notice recorded with the Bergen County Clerk. 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 Subsections D(15), (16), (17) and (18) 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 Subsection J(2)(e). 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.
(14)
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 Subsection D of this section 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 Bergen County Clerk and shall contain a description and location of the stormwater management measure, as well as reference to the maintenance plan, in accordance with Subsection D(13) 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 D(13) above.
(15)
Green infrastructure standards.
(a)
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.
(b)
To satisfy the groundwater recharge and stormwater runoff quality standards at Subsection D(16) and (17), the design engineer shall utilize green infrastructure BMPs identified in Table 1 at Subsection D(6) and/or an alternative stormwater management measure approved in accordance with Subsection D(7). The following green infrastructure BMPs are subject to the following maximum contributory drainage area limitations:

(d)
If a variance in accordance with N.J.A.C. 7:8-4.6 or a waiver from strict compliance in accordance with Subsection D(4) 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 Subsection D(7) may be used to meet the groundwater recharge, stormwater runoff quality, and stormwater runoff quantity standards at Subsection D(15), (16) and (17).
(e)
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 Subsection D(15), (16) and (17), unless the project is granted a waiver from strict compliance in accordance with Subsection D(4).
(16)
Groundwater recharge standards.
(a)
This subsection contains the minimum design and performance
standards for groundwater recharge as follows:
(b)
The design engineer shall, using the assumptions and factors for stormwater runoff and groundwater recharge calculations at Subsection E, either:
[1]
Demonstrate through hydrologic and hydraulic analysis that the
site and its stormwater management measures maintain 100% of the average
annual preconstruction groundwater recharge volume for the site; or
[2]
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.
(c)
This groundwater recharge requirement does not apply to projects within the urban redevelopment area, or to projects subject to Subsection D(16)(d) below.
(d)
The following types of stormwater shall not be recharged:
[1]
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
[2]
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.
(17)
Stormwater runoff quality standards.
(a)
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.
(b)
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:
[1]
Eighty 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.
[2]
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.
(c)
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 D(17)(b) 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.
(d)
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.

The TSS percent removal rate applicable to the second BMP.
|
(f)
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 Subsection D(15), (16) and (17).
(g)
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.
(h)
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.
(i)
Pursuant to the Flood Hazard Area Control Act Rules at N.J.A.C.
7:13-11.2(j)3i, 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.
(j)
This 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.
(18)
Stormwater runoff quantity standards.
(a)
This subsection contains the minimum design and performance
standards to control stormwater runoff quantity impacts of major development.
(b)
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at Subsection E, complete one of the following:
[1]
Demonstrate through hydrologic and hydraulic analysis that for
stormwater leaving the site, post-construction runoff hydrographs
for the two-, ten-, and 100-year storm events do not exceed, at any
point in time, the pre-construction runoff hydrographs for the same
storm events;
[2]
Demonstrate through hydrologic and hydraulic analysis that there
is no increase, as compared to the preconstruction condition, in the
peak runoff rates of stormwater leaving the site for the two-, ten-
and 100-year storm events 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;
[3]
Design stormwater management measures so that the post-construction
peak runoff rates for the two-, ten- and 100-year storm events are
50%, 75% and 80%, respectively, of the preconstruction 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
[4]
In tidal flood hazard areas, stormwater runoff quantity analysis in accordance with Subsection D(18)(b)[1]. [2] and [3] 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.
(c)
The stormwater runoff quantity standards shall be applied at
the site's boundary to each abutting lot, roadway, watercourse, or
receiving storm sewer system.
E.
Calculation of stormwater runoff and groundwater recharge.
(1)
Stormwater runoff shall be calculated in accordance with the following:
(a)
The design engineer shall calculate runoff using one of the
following methods:
[1]
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://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/stelprdb1044171.pdf
or at United States Department of Agriculture Natural Resources Conservation
Service, 220 Davison Avenue, Somerset, New Jersey 08873; or
[2]
The Rational Method for peak flow and the Modified Rational
Method for hydrograph computations. The rational and modified rational
methods are described in "Appendix A-9 Modified Rational Method" in
the Standards for Soil Erosion and Sediment Control in New Jersey,
January 2014. This document is available from the State Soil Conservation
Committee or any of the Soil Conservation Districts listed at N.J.A.C.

(b)
For the purpose of calculating runoff coefficients and groundwater recharge, there is a presumption that the preconstruction condition of a site or portion thereof is a wooded land use with good hydrologic condition. The term "runoff coefficient" applies to both the NRCS methodology above at Subsection E(1)(a)[1] and the Rational and Modified Rational Methods at Subsection E(1)(a)[2]. A runoff coefficient 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).
(c)
In computing preconstruction 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.
(d)
In computing stormwater runoff from all design storms, the design
engineer shall consider the relative stormwater runoff rates and/or
volumes of pervious and impervious surfaces separately to accurately
compute the rates and volume of stormwater runoff from the site. To
calculate runoff from unconnected impervious cover, urban impervious
area modifications as described in the NRCS Technical Release 55 -
Urban Hydrology for Small Watersheds or other methods may be employed.
(e)
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.
(2)
Groundwater recharge may be calculated in accordance with the following:
The New Jersey Geological Survey Report GSR-32, A Method for Evaluating
Groundwater-Recharge Areas in New Jersey, incorporated herein by reference

B.
Prior to the grant of final approval, the developer
shall submit to the Board a written instrument from each serving utility
which shall evidence full compliance with the provisions of this article;
provided, however, that lots which abut existing streets where overhead
electric or telephone distribution supply lines have theretofore been
installed on any portion of the streets involved may be supplied with
overhead service, but the service connections must be underground.
A.
General. Landscaping for site plans and subdivisions
shall be designed to:
(1)
Preserve and enhance the visual identity of the site,
neighborhood and Village as a whole;
(2)
Mitigate the potentially harmful effects of soil and
vegetative disturbance, lighting and noise;
(3)
Buffer incompatible uses;
(4)
Screen various improvements, including buildings,
parking and loading areas, utilities and drainage structures, storage
areas, etc., from streets and adjacent properties; and

electric and telephone lines or other utilities.
B.
General site landscaping. Any part or portion of the
site which is not used for buildings, accessory structures, loading
or parking spaces or aisles, sidewalks and designated storage areas
and which does not contain existing vegetation to remain shall be
landscaped in accordance with an overall landscape planting plan,
as approved by the Board. All landscaped portions of the site shall
be maintained adequately throughout the year.
C.
Protection of existing vegetation. Existing vegetation
shall be preserved to the maximum extent practicable. The following
shall apply:
(1)
Snow fence or silt fence shall be installed at the
limits of disturbance as shown on the approved development plans,
which shall be at a sufficient distance to prevent disturbance of
the root systems or branches of the vegetation to be preserved.
(2)

Any buffer provided between properties shall be sufficient to provide visual separation during all seasons and to minimize the effects of headlights from vehicles, light from structures, noise and the movements of people and vehicles. The following provisions shall apply, provided that additional and/or more restrictive standards may be required by the zoning regulations, Article X of this chapter.
[Amended 2-8-2017 by Ord.
No. 3579]
(1)
When topographical conditions, existing vegetation or other conditions
provide a sufficient buffer as determined by the Board, no additional
buffer shall be required.
(2)
Buffer depths. The depth of required buffers shall be sufficient
to accommodate the ultimate growth of any plantings in the buffer.
(3)
Trees and shrubs used in a buffer for screening purposes shall be
at least five feet high at the time of planting, and shall be of a
species that will naturally grow to such additional height within
five years as needed to provide a suitable visual screen, as determined
by the reviewing board. The spacing of the trees and shrubs shall
be designed to accommodate the mature spread of the plant species
and to provide a suitable visual screen within five years, again as
determined by the reviewing board.
(4)
Buffers shall be protected from impact by motor vehicles and from
the negative effects of road salt and snowplowing. A curb, bumper
guard or the equivalent at least five inches in height above the pavement
shall separate buffers from vehicle use areas, provided that utility
poles or railroad ties shall not be used.
(5)
In cases where berms, fences and/or walls are proposed or required,
the reviewing board shall determine the required location of such
features, taking into consideration topography, the location of existing
structures, trees and other vegetation to remain, sight lines and
other factors as necessary to determine the location where such features
would provide the most effective screen and would not unduly impair
the design and function of the subject properties.
