A. 
The subdivider shall install or guarantee the installation of such of the following improvements or portions thereof as may be required by the governing body: street grading and pavement or other surfacing; gutters, curbs and sidewalks; shade trees; streetlighting; street signs; water mains, culverts, storm sewers, sanitary sewers or dry sewers or other means of sewage disposal; drainage structures; and all appurtenances to such facilities properly connected with approved systems of water supplies, sewage and stormwater drainage, as the case may be.
B. 
Such requirements shall take account of the characteristics of potential development of various parts of the Township as reflected in the comprehensive land use plan embodied in the Zoning Ordinance,[1] with a view to providing safe, convenient and pleasant means for the movement of traffic appropriate to the streets of the various classes defined in this chapter and protecting the public health, safety, comfort and convenience by provision for the proper distribution of water and for adequate sewage and storm-water drainage in a manner appropriate to the existing and prospective type and intensity of development in various parts of the Township and in arrangements that will not impose unnecessary financial burdens on property owners or add to the normal costs of operation of the government of the Township.
[1]
Editor's Note: See Ch. 430, Zoning.
C. 
The standards in this chapter shall be deemed to be the minimum standards necessary for any particular subdivision.
D. 
All improvements shall be installed in accordance with the specifications contained in this article.
E. 
It shall be expressly understood that, notwithstanding the posting of a performance guaranty for a lot in a major residential subdivision, no building permit shall be issued until the subdivider shall have installed the road subbase, road base and curbs in accordance with the Township specifications and as certified by the Township Engineer, and until the underground utilities, such as sewer, water and storm drainage lines, and all other underground work shall have been duly and properly installed. In a major subdivision for which the use of land is restricted by zoning to nonresidential uses, building permits may be issued prior to completion of road base, curbs, underground water, sewer and storm drainage lines, provided that adequate posting of performance guaranties has been completed. No final certificate of occupancy for residential and nonresidential buildings shall be issued until all improvements have been completed and approved by the Township, for which a performance guaranty is posted.
F. 
Before a final subdivision plat or final site plan shall be approved, the applicant shall execute a developer's agreement with the Township, providing such reasonable conditions as the Township Council finds necessary to assure that the required improvements shall be properly installed and will function so as not to create any nuisance or conditions adverse to the public interest.
[Added 5-24-1983 by Ord. No. 83:39]
G. 
For all improvements or portions thereof, which will ultimately be owned and maintained by the Township, the developer shall use only manufactured and farm products of the United States, wherever available, in the construction of the improvements.
[Added 5-27-1986 by Ord. No. 86:31]
[Amended 12-27-1983 by Ord. No. 83:90; 4-30-2002 by Ord. No. 2002:12]
A. 
Where the need for off-tract improvements for water, sewer, drainage and street improvements and for other improvements as provided by law are, in whole or in part, made necessary by the application of the developer, and the installation of the improvements would confer a benefit upon the development, a determination of the contribution of the developer for said off-tract improvements shall be made in accordance with the provisions as hereinafter set forth. The requirements for off-tract roadway and intersection improvements are detailed in § 225-59.
B. 
Determinations by Planning Board. The Planning Board shall review all subdivision and site plan applications to determine their impact on the Township's infrastructure, with the assistance of the appropriate Township agencies, including but not limited to the Township Engineer, the Sewer and Water Superintendents and the Township Planner. Thereafter, the Planning Board shall, with the assistance of such agencies:
(1) 
Determine the need for off-tract improvements.
(2) 
Determine the total cost of the off-tract improvement.
(3) 
Determine the amount by which all properties to be serviced thereby, including the applicant's property, will be specially benefited therefrom.
(4) 
In cases where reasonable and necessary need for the off-tract improvement or improvements is necessitated or required by the proposed development application and where no other property owners receive a special benefit thereby, the Planning Board shall require the applicant, as a condition of approval, at the applicant's expense, to provide for and construct such improvements as if such were on-tract improvements and shall forward a report of their findings forthwith to the governing body.
(5) 
In cases where the need for off-tract improvements is necessitated by the proposed development application and where the Planning Board determines that properties outside the development will be benefited by the improvements, the Planning Board shall forthwith forward to the governing body a report containing a list and description of all such improvements, together with its request that the governing body determine and advise the Planning Board of the procedure to be followed in the construction or installation thereof.
(6) 
In cases where the Planning Board determines that no off-tract improvements are required, a report summarizing its findings shall forthwith be forwarded to the governing body.
C. 
Determination by governing body. Upon receipt of the recommendations and report of the Planning Board, the governing body shall, within 30 days from the receipt thereof, determine and advise the Planning Board whether:
(1) 
The recommended off-tract improvement should be undertaken based upon the best interests of the Township.
(2) 
The improvement is to be constructed or installed by the municipality as a general improvement or as a local improvement.
(3) 
The improvement is to be constructed or installed by the developer under a formula providing for partial reimbursement by the Township for benefits to properties other than the development.
D. 
Amount of contribution. When this has been determined, the developer may be required to provide, as a condition for final approval of the development, a bond or a cash deposit to insure payment to the Township of one of the following amounts:
(1) 
If the improvement is to be constructed by the Township as a general improvement, an amount equal to the difference between the estimated cost of the improvement and the estimated total amount by which all properties to be serviced thereby, including the developer's property, will be specially benefited by the off-tract improvement.
(2) 
If the improvement is to be constructed by the Township as a local improvement, the estimated amount by which the subdivision will be specially benefited by the off-tract improvement.
(3) 
If the improvement is to be constructed by the developer, an amount equal to the estimated cost of the off-tract improvement, less an offset for benefits to properties other than the subdivision.
E. 
Determination of special benefits. In determining benefits conferred on properties specially benefited by an off-tract improvement, the following formula shall, subject to adjustment for peculiar or exceptional conditions, be used:
(1) 
The development shall be allocated that percentage of 100 computed by dividing the development land area by the total land area benefited by the off-tract improvement; and/or the development shall be allotted that percentage of 100 computed by dividing the maximum potential intensity of use of the development (total square feet of building floor area) by the maximum potential intensity of use under existing zoning limitation in the total land area benefited by the off-tract improvement.
(2) 
In the case of linear improvements, i.e., roads, curbing, sidewalks, pipes, drains, sewers, drainage easements, etc., the development shall be allotted that percentage of 100 computed by dividing the distance (measured along the course of the off-tract improvement) from the connecting facility to the farthest abutting point of the subdivision by the sum of the distance of all intervening properties, including the developments abutting the off-tract improvement similarly measured.
(3) 
In determining whether the foregoing formula should be adjusted because of peculiar or exceptional circumstances, the following criteria shall be considered: the increase in market value of the property affected and any other benefits conferred, the needs created by the application, population and land use projections for the general area of an applicant's property and other areas to be served by the off-tract improvements, the estimated time of construction, the condition and period of usefulness of the improvements, increase of traffic generated by the development and the drainage created by or affected by any particular land use.
F. 
Payment of allocated cost.
(1) 
The estimated cost plus a reasonable inflation cost for the off-tract improvement allocated to the developer, if deposited in cash, shall be paid by the developer to the Township Treasurer. If such improvements are not initiated by the Township within a period of 10 years from the day of payment, then funds so deposited shall be returned, together with interest at the prevailing rates less 1% for administration costs.
(2) 
In the event the payment by the developer to the Township Treasurer provided for herein is less than its share of the actual cost of the off-tract improvements, then it shall be required to pay its additional share of the cost thereof.
(3) 
In the event the payment by a developer to the Township Treasurer provided for above is more than its appropriate share of the actual cost of installation of the off-tract improvements, it shall be repaid an amount equal to the difference between the deposit and its share of the actual cost.
G. 
Assessment of properties. Upon receipt from the developer of its allocated share of the costs of the off-tract improvements, the Township may adopt a local improvement assessment ordinance for the purpose of construction and installation of the off-tract improvements, based upon the cost of the project, including administration and finance charges. Any portion of the cost of the improvements not defrayed by a developer may be assessed against benefiting property owners by the Township. Any assessments for benefits conferred made against the developer or its successors in interest shall be first offset by a pro rata share credit of the allocated costs previously deposited with the Township Treasurer pertaining thereto. The developer or its successors in interest shall not be liable for any part of an assessment for such improvements unless the assessment exceeds its pro rata share credit for its deposit, and then only to the extent of the deficiency.
H. 
Credit for work performed. In the event the developer installs and constructs an off-tract improvement on any portion thereof, which improvement is accepted by the Township, then the cost shall be treated as a credit against any future assessment for that particular off-tract improvement or portion thereof constructed by the Township in the same manner as if the developer had deposited its apportioned cost with the Township Treasurer, as provided herein.
I. 
Installation of improvements by applicant. At the discretion and option of the Township, the Township may enter into a contract with the developer providing for the installation and construction of the off-tract improvements by the developer upon contribution by the Township of the remaining unallocated portion of the cost of the off-tract improvement. In the event the Township so elected to contribute to the cost and expense of installation of the off-tract improvements by the developer, the portion contributed by the Township shall be subject to possible certification and assessment as a local improvement against benefiting property owners in the manner provided by law, if applicable.
J. 
Design standards. Should the developer and the Township enter into a contract for the construction and erection of the off-tract improvements to be done by the developer, it shall observe all requirements and principles of this chapter and other ordinances in the design of such improvements.
K. 
The terms herein set forth shall be a condition of either preliminary approval or final approval of a subdivision or site plan. If not imposed as a condition of preliminary approval, such off-tract improvements and the apportionment of the cost thereof shall be considered improvements under N.J.S.A. 40:55D-1 et seq., which may be imposed at the time of final approval.
L. 
Notice and appeal. Before apportioning the cost of off-tract improvements to a developer, the Planning Board shall notify and afford the developer an opportunity to be heard thereon at a public meeting. The developer may appeal to the governing body's confirmation as provided by law.[1]

Editor's Note: Former Subsection M, Off-tract water supply and distribution improvements, added 6-9-1987 by Ord. No. 87:29, which immediately followed this subsection, was repealed 10-23-1990 by Ord. No. 90:75.
[Added 4-30-2002 by Ord. No. 2002:12]
A. 
Traffic impact study. The purpose of traffic impact studies is to assess the effect of new development, expansions and redevelopment projects on the existing public street network, including pedestrian and public transit facilities. These studies are also to examine the functional relationship between the site access, circulation and parking systems (as appropriate) and the public street system. As such, traffic impact studies are necessary to evaluate the appropriateness of the site development within the context of the public street system and to identify any necessary public infrastructure improvements needed to accommodate the traffic demands generated by the proposed use.
B. 
When required. Traffic impact studies are required to be submitted for site plan applications when:
(1) 
Access is or will be provided at an existing signalized intersection along a public road.
(2) 
Signalized access to a public road is proposed by the applicant or is required by the Township Engineer or the Township Traffic Engineer.
(3) 
The proposed development, redevelopment and/or expansion results in a net increase of 25 or more peak hour trips in any given peak hour period (a.m., p.m. or Saturday). This threshold is not to include any credits for pass-by traffic. Peak hour trip calculations are to be based upon the current edition of the ITE Trip Generation Manual or, if data is not available or is limited in scope, site specific data can be substituted. Credit for existing traffic (based upon the ITE Trip Generation Manual) is to be allowed for existing development on the property in question subject to approval by the Township Engineer or the Township Traffic Engineer.
(4) 
When determined by the Township Engineer or the Township Traffic Engineer to be necessary due to specific and/or unique site and roadway conditions.
C. 
Content. In general, traffic impact studies shall contain the following components:
(1) 
Description of existing roadways.
(2) 
Existing traffic volume information. Traffic counts are to generally be conducted between Tuesday and Thursday and not on days immediately preceding or following holidays. For retail and mixed use developments, Friday and Saturday periods are required. Traffic counts are generally to be performed during the 7:00 a.m. to 9:00 a.m. and 4:00 p.m. to 6:00 p.m. periods on weekdays and between 11:00 a.m. and 3:00 p.m. on Saturdays unless there are other specific concerns or the proposed use has different peak periods. A peak hour for each time period shall be defined as the four consecutive fifteen-minute intervals with the highest total volume, and said peak hour volumes shall be used in all analysis.
(3) 
Existing levels of service and evaluation of existing operating conditions (using approved capacity analysis software).
(4) 
Description of proposed project, including the type and size (number of units, seats, square footage, etc.) of development.
(5) 
Trip generation calculations based upon the ITE Trip Generation Manual (most current edition available), including pass-by trip calculations. If other data sources are used to project site traffic, the basis of the trip generation must be approved by the Township Engineer or the Township Traffic Engineer.
(6) 
Trip distribution, including the basis for the distribution (gravity model, existing traffic patterns, etc.).
(7) 
Site-generated traffic will be assigned to the roadway network based upon minimum travel times and knowledge of the travel patterns within the study area.
(8) 
Determination of future build year or years if a phased project.
(9) 
Background traffic growth projections, including regional traffic growth (based upon annualized growth factors published by NJDOT) and other specific projects within the influence area of the proposed project.
(10) 
Future no-build traffic volumes and future build traffic volumes.
(11) 
Evaluation of future no-build and build levels of service and operating conditions (using approved capacity analysis software). Level of service results are to be reported on a per-approach movement basis.
(12) 
Identification and evaluation of proposed mitigation measures and other roadway improvements, including any needed safety improvements.
(13) 
Discussion of site access, sight distances and circulation, including pedestrian elements.
(14) 
Graphics are to include a location map, existing and proposed lane usage diagrams and volume networks for each analysis period. Graphics are also to be provided for site-generated traffic, separating new traffic volumes, pass-by volumes and any other unique volume adjustments (existing traffic volume credits, etc.).
(15) 
Copies of capacity analyses and traffic count data are to be included as appendixes.
(16) 
A discussion of the site plan elements, including but not limited to, sight distances, parking, circulation, loading, access design and location and recommended traffic control measures.
D. 
Study area. The extent of the study area, those intersections to be analyzed, will vary depending upon the size and nature of the proposed project and the amount of traffic to be generated. The following locations are to be included in the study area:
(1) 
For all projects that result in a net increase of 25 or more peak hour trips in any given peak hour period (a.m., p.m. or Saturday), exclusive of credits for pass-by traffic, the following intersections shall be included:
(a) 
The traffic study will be required to evaluate the impacts at the intersections of the proposed site driveways or streets with the public road network.
(b) 
The traffic study is required to include the first signalized intersection on a public road in each direction from any site driveway, up to a maximum distance of two miles.
(c) 
Any signalized intersection that will service 25 or more new peak hour trips from the proposed development shall be included in the study area. The analysis requirement shall also apply to unsignalized intersections if the proposed development will increase traffic on the minor street approach. Along divided roadways, ramp junctions and weaving sections are also to be considered applicable analysis locations.
E. 
Level of service standards. For all intersections (both signalized and unsignalized), lane groups with left turn movements must be maintained at Level of Service D and all other lane groups must be maintained at Level of Service C, as described in the Highway Capacity Manual, Special Report 209, published by the Transportation Research Board. In situations where the no-build level of service does not achieve Level of Service D for lane groups with left turns and Level of Service C for other lane groups, the no-build delay, rounded to the nearest second, must not be degraded.
(1) 
If the above level of service standards are not exceeded in the no-build condition, each development is permitted to increase no-build delay by the lesser of the difference between the no-build delay and the upper end of the delay range for the above level of service standards, or a maximum of 5 seconds, rounded to the nearest second. Any traffic above this threshold shall be considered a violation component of site traffic. If the above level of service standards are exceeded in the no-build condition, all site traffic shall be considered part of the violation component. Any site traffic that can be accommodated without violating the above requirements shall be considered nonviolation site traffic, with the remainder of site generated traffic being the violation component of site traffic.
(2) 
For any locations not meeting the above level of service standards, the traffic impact study must provide a conceptual improvement plan to mitigate the traffic impacts of the site, subject to the review and approval of the Township Engineer or the Township Traffic Engineer.
(3) 
For unsignalized driveways, movements exiting the driveway must be maintained at Level of Service E, as described in the Highway Capacity Manual, Special Report 209, published by the Transportation Research Board, during all time periods.
F. 
Determination of fair share contribution. The traffic impact study must include an estimate of the probable construction costs of any mitigation improvements, subject to the review and approval of the Township Engineer or the Township Traffic Engineer. Improvement costs are to include design costs, right-of-way appraisal and acquisition, construction, construction management and permitting.
(1) 
The developer's contributions for these improvements will be apportioned based upon the violation component of site traffic added to the specific intersection divided by the increase in the capacity of the intersection, as shown in the following equation:
Fair Share Contribution
=
(Violation Component of Site Traffic)
(Capacity Increase)
(2) 
The capacity of the intersection (both in the pre- and post-mitigation cases) shall be determined by incrementing the traffic volume through the intersection until the most critical movement reaches the upper threshold of level of service as described in the Highway Capacity Manual, Special Report 209, published by the Transportation Research Board. In performing capacity calculations, the future build volumes shall be utilized, and all signal phasing and timings shall be held constant.
(3) 
The capacity increase of the mitigation shall be determined in the following manner:
Capacity Increase = (Capacity after Mitigation) - (Capacity with Mitigation)
(4) 
In the case where level of service standards are violated during multiple time periods (e.g., a.m. and p.m. peak hours), the fair share contribution for each time period shall be calculated independently, and the worst case (i.e., highest fair share contribution) shall apply.
(5) 
Improvements that solely benefit the development site (e.g., signalized driveways, left turn lanes, acceleration lanes) are not considered off-tract improvements and, consequently, are not subject to fair share contribution calculations. The costs associated with these improvements shall be considered on-tract improvements and, hence, are the sole responsibility of the applicant.
(6) 
For sites that require access permits from the New Jersey Department of Transportation (i.e., sites with driveways on roadways under the jurisdiction of the New Jersey Department of Transportation), fair share obligations under the New Jersey Department of Transportation Access Management Code supersede the above obligations for intersections under state jurisdiction only.
Grades and cross sections shall be such as to provide for the disposal of stormwater and such groundwater seepage as may be encountered, all in accordance with the plans therefor approved at the time of the approval of the tentative plan of the subdivision and as may be required in the field by the Director of Public Works or the Township Engineer as the work progresses. All underground utilities, drains or other facilities located within the roadway portion of a street shall be installed prior to the placing of any road-surfacing material.
[Added 3-14-2000 by Ord. No. 2000:6]
Retaining walls greater than six feet in height shall be tiered at every six-foot interval of height. Each tier shall be set back a minimum of three feet to provide for the placement of landscape plantings at each tier level. Landscaping shall be required at each tier level to reduce the appearance of height and mass of the retaining wall. This requirement shall not apply to any development for which preliminary major subdivision approval, preliminary major site plan approval, final subdivision approval or final site plan approval was granted by a resolution of approval adopted by the Planning Board prior to the adoption of this provision, and which approval has not expired. In such cases, the requirements and conditions contained in the resolution of approval shall apply.

The following listing of structure numbers shall be used in determining a depth, type and structure of pavements:
(a) 
Hot mix bituminous concrete per compacted inch: 0.44.
(5) 
Reduction allowance.
(a) 
In cases where the subgrade will achieve a California bearing ratio of 10 or better, the requirement of the structural number can be reduced by 0.44 or the bituminous stabilized base course can be reduced by one inch in thickness.
(b) 
In order to qualify for this reduction allowance, a test must be taken every 500 linear feet of roadway with a minimum of three tests per site.
(c) 
Additional tests may be as directed by the Engineer for special cases.
(d) 
All tests shall be performed by a recognized testing laboratory.
A. 
The purpose of this section shall be to preserve, create and improve the character and values of properties being subdivided in which new roads are being created by providing for shade trees along the right-of-way. These provisions shall apply to all types of roads referred to under Article IX, except collector streets (industrial, business and commercial).
B. 
All the varieties of trees listed under Schedule 1 in Subsection O(1) below, or such other species that are approved by the enforcing officer, which are two inches in diameter or larger at four feet above the graded ground and growing in the three-foot strip of the right-of-way adjacent to the lot lines, shall be left standing and undamaged, except that:
(1) 
All trees of the varieties listed in Schedule 1 in Subsection O(1), in excess of one tree every 50 feet averaged on the three-foot strip each side of the right-of-way (but not less than 35 feet nor more than 75 feet apart), may be removed.
(2) 
In the case of marginal roads, it shall be necessary to have trees on only the side of the road adjacent to the proposed lots, spaced as directed in Subsection B(1) above.
(3) 
If necessary, because of excessive grading and by special permission of the Planning Board, all existing trees may be removed and new trees planted in accordance with Subsection C below.

[Amended 9-18-2007 by Ord. No. 2007:27]
(1) 
Scope and purpose.
(a) 
Policy statement. Flood control, groundwater recharge, and pollutant reduction through nonstructural or low-impact techniques shall be explored before relying on structural BMPs. Structural BMPs should be integrated with nonstructural stormwater management strategies and proper maintenance plans. Nonstructural strategies include both environmentally sensitive site design and source controls that prevent pollutants from being placed on the site or from being exposed to stormwater. Source control plans 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.
(b) 
Purpose. It is the purpose of this subsection to establish minimum stormwater management requirements and controls for major development, as defined in Subsection L(2), below.
(c) 
Applicability.
[1] 
This subsection shall be applicable to all site plans and subdivisions for the following major developments that require preliminary or final site plan or subdivision review:
[a] 
Nonresidential major developments; and
[b] 
Aspects of residential major developments that are not preempted by the Residential Site Improvement Standards, N.J.A.C. 5:21.
[2] 
This subsection shall also be applicable to all major developments undertaken by the Township of Parsippany-Troy Hills.
(d) 
Compatibility with other permit and ordinance requirements. Development approvals issued for subdivisions and site plans pursuant to this subsection are to be considered an integral part of development approvals under the subdivision and site plan review process 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 subsection shall be held to be the minimum requirements for the promotion of the public health, safety, and general welfare. This subsection 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 subsection 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.
(2) 
Definitions. Unless specifically defined below, words or phrases used in this subsection shall be interpreted so as to give them the meaning they have in common usage and to give this subsection its most reasonable application. The definitions below are the same as or based on the corresponding definitions in the Stormwater Management Rules at N.J.A.C. 7:8-1.2.

General standards.
(a) 
Design and performance standards for stormwater management measures.
[1] 
Stormwater management measures for major development shall be developed to meet the erosion control, groundwater recharge, stormwater runoff quantity, and stormwater runoff quality standards in Subsection L(4). To the maximum extent practicable, these standards shall be met by incorporating nonstructural stormwater management strategies into the design. If these strategies alone are not sufficient to meet these standards, structural stormwater management measures necessary to meet these standards shall be incorporated into the design.
[2] 
The standards in this subsection 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.
(4) 
Stormwater management requirements for major development.
(a) 
The development shall incorporate a maintenance plan for the stormwater management measures incorporated into the design of a major development in accordance with Subsection L(10), below.
(b) 
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 15.150, particularly Helonias bullata (swamp pink) and/or Clemmys muhlnebergi (bog turtle).
(c) 
The following linear development projects are exempt from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements of Subsection L(4)(f) and (g):
[1] 
The construction of an underground utility line, provided that the disturbed areas are revegetated upon completion;
[2] 
The construction of an aboveground utility line, provided that the existing conditions are maintained to the maximum extent practicable; and
[3] 
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.
(d) 
A waiver from strict compliance from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements of Subsection L(4)(f) and (g) 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:
[1] 
The applicant demonstrates that there is a public need for the project that cannot be accomplished by any other means;
[2] 
The applicant demonstrates through an alternatives analysis that, through the use of nonstructural and structural stormwater management strategies and measures, the option selected complies with the requirements of Subsection L(4)(f) and (g) to the maximum extent practicable;
[3] 
The applicant demonstrates that, in order to meet the requirements of Subsection L(4)(f) and (g) existing structures currently in use, such as homes and buildings, would need to be condemned; and
[4] 
The applicant demonstrates that it does not own or have other rights to the areas, including the potential to obtain through condemnation lands not falling under Subsection L(4)(d)[3] above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate the requirements of Subsection L(4)(f) and (g) that were not achievable on site.
(e) 
Nonstructural stormwater management strategies.
[1] 
To the maximum extent practicable, the standards in Subsection L(4)(f) and (g) shall be met by incorporating nonstructural stormwater management strategies set forth in Subsection L(4)(e) into the design. The applicant shall identify the nonstructural measures incorporated into the design of the project. If the applicant contends that it is not feasible for engineering, environmental, or safety reasons to incorporate any nonstructural stormwater management measures identified in Subsection L(4)(e)[2] below into the design of a particular project, the applicant shall identify the strategy considered and provide a basis for the contention.
[2] 
Nonstructural stormwater management strategies incorporated into site design shall:
[a] 
Protect areas that provide water quality benefits or areas particularly susceptible to erosion and sediment loss;
[b] 
Minimize impervious surfaces and break up or disconnect the flow of runoff over impervious surfaces;
[c] 
Maximize the protection of natural drainage features and vegetation;
[d] 
Minimize the decrease in the time of concentration from preconstruction to postconstruction. "Time of concentration" is defined as the time it takes for runoff to travel from the hydraulically most distant point of the watershed to the point of interest within a watershed;
[e] 
Minimize land disturbance including clearing and grading;
[f] 
Minimize soil compaction;
[g] 
Provide low-maintenance landscaping that encourages retention and planting of native vegetation and minimizes the use of lawns, fertilizers and pesticides;
[h] 
Provide vegetated open-channel conveyance systems discharging into and through stable vegetated areas;
[i] 
Provide other source controls to prevent or minimize the use or exposure of pollutants at the site, in order to prevent or minimize the release of those pollutants into stormwater runoff. Such source controls include, but are not limited to:
[i] 
Site design features that help to prevent accumulation of trash and debris in drainage systems, including features that satisfy Subsection L(4)(e)[3] below;
[ii] 
Site design features that help to prevent discharge of trash and debris from drainage systems;
[iii] 
Site design features that help to prevent and/or contain spills or other harmful accumulations of pollutants at industrial or commercial developments; and
[iv] 
When establishing vegetation after land disturbance, applying fertilizer in accordance with the requirements established under the Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., and implementing rules.
[3] 
Site design features identified under Subsection L(4)(e)[2][i][ii], above shall comply with the following standard to control passage of solid and floatable materials through storm drain inlets. For purposes of this paragraph, "solid and floatable materials" means sediment, debris, trash, and other floating, suspended, or settleable solids. For exemptions to this standard see Subsection F(4)(e)[3][c], below.
[a] 
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: 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 a different grate, if each individual clear space in that grate has an area of no more than seven square inches, or is no greater than two inches across the smallest dimension. 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 seven square inches, or be no greater than two inches across the smallest dimension.
[c] 
This standard does not apply:
[i] 
Where the review agency determines that this standard would cause inadequate hydraulic performance that could not practicably be overcome by using additional or larger storm drain inlets that meet these standards;
[ii] 
Where flows from the water quality design storm as specified in Subsection L(4)(g)[1] are conveyed through any device (e.g., end-of-pipe netting facility, manufactured treatment device, or a catch basin hood) that is designed, at a minimum, to prevent 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 inches.
[iii] 
Where flows are conveyed through a trash rack that has parallel bars with one-inch spacing between the bars, to the elevation of the water quality design storm as specified in Subsection L(4)(g)[1], below; or
[iv] 
Where the New Jersey Department of Environmental Protection determines, pursuant to the New Jersey Register of Historic Places Rules at N.J.A.C. 7:4-7.20, that action to meet this standard is an undertaking that constitutes an encroachment or will damage or destroy the New Jersey Register listed historic property.
[4] 
Any land area used as a nonstructural stormwater management measure to meet the performance standards in Subsection L(4)(f) and (g) shall be dedicated to a government agency, subjected to a conservation restriction filed with the appropriate county clerk's office, or subject to an approved equivalent restriction that ensures that measure or an equivalent stormwater management measure approved by the reviewing agency is maintained in perpetuity.
[5] 
Guidance for nonstructural stormwater management strategies is available in the New Jersey Stormwater Best Management Practices Manual. The BMP Manual may be obtained from the address identified in Subsection L(7), or found on the Department's Web site at www.njstormwater.com.

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
[B] 
Demonstrate through hydrologic and hydraulic analysis that the increase of stormwater runoff volume from preconstruction for the two-year storm is infiltrated.
[ii] 
This groundwater recharge requirement does not apply to projects within the urban redevelopment area, or to projects subject to Subsection L(4)(f)[1][a][iii] below.
[iii] 
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.
[iv] 
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 and other subsurface structures in the vicinity or downgradient of the groundwater recharge area.
[c] 
In order to control stormwater runoff quantity impacts, the design engineer shall, using the assumptions and factors for stormwater runoff calculations at Subsection F(5), below, complete one of the following:
[i] 
Demonstrate through hydrologic or hydraulic analysis that for stormwater leaving the site, postconstruction runoff hydrographs for the two-, ten-, and one-hundred-year storm events do not exceed, at any point in time, the preconstruction runoff hydrographs for the same storm events;
[ii] 
Demonstrate through hydrologic or 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 one-hundred-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;
[iii] 
Design stormwater management measure so that the postconstruction peak runoff rates for the two-, ten-, and one-hundred-year storm events are 50%, 75%, and 80%, respectively, of the preconstruction peak runoff rates. The percentages apply only to the postconstruction stormwater runoff that is attributable to the portion of the site on which the proposed development or project is to be constructed. The percentages shall not be applied to postconstruction stormwater runoff into tidal flood hazard areas if the increased volume of stormwater runoff will not increase flood damages below the point of discharge.
(g) 
Stormwater runoff quality standards.
[1] 
Stormwater management measures shall be designed to reduce the postconstruction load of total suspended solids (TSS) in stormwater runoff by 80% of the anticipated load from the developed site, expressed as an annual average. Stormwater management measures shall only be required for water quality control if an additional 1/4 acre of impervious surface is being proposed on a development site. 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 Pollution Discharge Elimination System (NJPDES) rules, N.J.A.C. 7:14A, or in a discharge specifically exempt under a NJDES permit from this requirement. 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 1. The calculation of the volume of runoff may take into account the implementation of nonstructural and structural stormwater management.
[2] 
For purposes of TSS reduction calculations, Table 2 below presents the presumed removal rates for certain BMPs designed in accordance with the New Jersey Stormwater Best Management Practices Manual. The BMP Manual may be obtained from the address identified in Subsection L(7), or found on the Department's Web site at www.njstormwater.com. The BMP Manual and other sources of technical guidance are listed in Subsection L(7). TSS reduction shall be calculated based on the removal rates for the BMPs in Table 2 below. Alternative removal rates and methods of calculating removal rates may be used if the design engineer provides documentation demonstrating the capability of these alternative rates and methods to the review agency. A copy of any approved alternative rate or method of calculating the removal rate shall be provided to the Department at the following address: Division of Watershed Management, New Jersey Department of Environmental Protection, P.O. Box 418, Trenton, New Jersey 08625-0418.
[3] 
If more than one BMP in series is necessary to achieve the required eighty-percent TSS reduction for a site, the applicant shall utilize the following formula to calculate TSS reduction:
R = A + B - AB/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

If there is more than one on-site drainage area, the eighty-percent TSS removal rate shall apply to each drainage area, unless the runoff from the subareas converge on site, in which case the removal rate can be demonstrated through a calculation using a weighted average.
[5] 
Stormwater management measures shall also be designed to reduce, to the maximum extent feasible, the postconstruction 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 nonstructural strategies and structural measures that optimize nutrient removal while still achieving the performance standards in Subsection L(4)(f) and (g).
[6] 
Additional information and examples are contained in the New Jersey Stormwater Best Management Practices Manual, which may be obtained from the address identified in Subsection L(7).
[7]

[8] 
Special water resource protection areas shall be established along all waters designated Category One at N.J.A.C. 7:9B, and perennial or intermittent streams that drain into or upstream of the Category One waters as shown on the USGS Quadrangle Maps or in the County Soil Surveys, within the associated HUC14 drainage area. These areas shall be established for the protection of water quality, aesthetic value, exceptional ecological significance, exceptional recreational significance, exceptional water supply significance, and exceptional fisheries significance of those established Category One waters. These areas shall be designated and protected as follows:

[ii] 
Encroachment within the designated special water resource protection area under Subsection L(4)(g)[8][a][i] above shall only be allowed where previous development or disturbance has occurred (for example, active agricultural use, parking area or maintained lawn area). The encroachment shall only be allowed where the applicant demonstrates that the functional value and overall condition of the special water resource protection area will be maintained to the maximum extent practicable. In no case shall the remaining special water resource protection area be reduced to less than 150 feet as measured perpendicular to the top-of-bank of the waterway or center line of the waterway where the bank is undefined. All encroachments proposed under this subparagraph shall be subject to review and approval by the Department.
[b] 
All stormwater shall be discharged outside of and flow through the special water resource protection area and shall comply with the standard for off-site stability in the Standards for Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq.
[c] 
If stormwater discharged outside of and flowing through the special water resource protection area cannot comply with the standard for off-site stability in the Standards for Soil Erosion and Sediment Control Act, N.J.S.A. 4:24-39 et seq., then the stabilization measures in accordance with the requirements of the above standards may be placed within the special water resource protection area, provided that:

[vi] 
All encroachments proposed under this section shall be subject to review and approval by the Department.
(5) 
Calculation of stormwater runoff and groundwater recharge.
(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 Equation and Dimensionless Unit Hydrograph, as directed in the NRCS National Engineering Handbook Section 4 — Hydrology and Technical Release 55 — Urban Hydrology for Small Watersheds; or
[b] 
The Rational Method for peak flow and the Modified Rational Method for hydrograph computations.
[2] 
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 at Subsection L(5)(a)[1][a] and the Rational and Modified Rational Methods at Subsection L(5)(a)[1][b]. 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 have 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 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 preconstruction stormwater runoff rates and volumes.
[4] 
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 and other methods may be employed.
[5] 
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:
