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
B. Purpose. It is the purpose of this chapter to establish minimum stormwater management requirements and controls for "major development," as defined in § 202-2.
(1) This chapter shall be applicable to all site plans and
subdivisions for the following major developments that require preliminary
or final site plan or subdivision review:

preempted by the Residential Site Improvement Standards at N.J.A.C. 5:21.
undertaken by the Borough of Mountain Lakes.
Development approvals issued for subdivisions and site plans pursuant to this
chapter 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 chapter shall be held
to be the minimum requirements for the promotion of the public health, safety,
and general welfare. This chapter is not intended to interfere with, abrogate,
or annul any other ordinances, rule or regulation, statute, or other provision
different from those imposed by any other ordinance, rule or regulation, or
other provision of law, the more restrictive provisions or higher standards
and to give this chapter 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.

(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 § 202-4. 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.

C. The following linear development projects are exempt from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements of Subsections F and G:
D. A waiver from strict compliance from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements of Subsections 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:
(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 Subsections F and G to the maximum extent practicable;
(3) The applicant demonstrates that, in order to meet the requirements of Subsections 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 areas, including the potential to obtain through condemnation lands not falling under Subsection D(3) above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate the requirements of Subsections F and G that were not achievable on site.
(1) To the maximum extent practicable, the standards in Subsections F and G shall be met by incorporating nonstructural stormwater management strategies set forth at Subsection 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 E(2) below into the design of a particular project, the applicant shall identify the strategy considered and provide a basis for the contention.

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;
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;
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.
(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. 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.
the required eighty-percent TSS reduction for a site, the applicant shall
utilize the following formula to calculate TSS reduction:
See New Jersey Best Practices Management Manual
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 Subsections F and G.

and Technical Release 55, Urban Hydrology for Small Watersheds; or
(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 and the
Rational and Modified Rational Methods. 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).

(2) Structural 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 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 § 202-8D.

(a) If a stormwater management basin has an outlet structure, escape provisions shall be incorporated in or on the structure. With the prior approval of the reviewing agency identified in § 202-8C a freestanding outlet structure may be exempted from this requirement.
(b) Safety ledges shall be constructed on the slopes of all new stormwater management basins having a permanent pool of water deeper than 2 1/2 feet. Such safety ledges shall be comprised of two steps. Each step shall be four to six feet in width. One step shall be located approximately 2 1/2 feet below the permanent water surface, and the second step shall be located one to 1 1/2 feet above the permanent water surface. See § 202-8D for an illustration of safety ledges in a stormwater management basin.
C. Variance or exemption from safety standards. A variance
or exemption from the safety standards for stormwater management basins may
be granted only upon a written finding by the appropriate reviewing agency
(municipality, county or Department) that the variance or exemption will not
constitute a threat to public safety.
