(Ord. No. 2063-06 § 2) 25-29.3 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 this section. To the maximum extent feasible, 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 ordinance 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. Such alternative standards shall provide at least as much protection from stormwater-related

lan or Water Quality Management Plan adopted in accordance with Department rules. Such alternative standards shall provide at least as much protection from stormwater-related loss of groundwater recharge, stormwater quantity and water quality impacts of major development projects as would be provided under the standards in this section. 3. For site improvements regulated under the Residential Site Improvement Standards (RSIS) at N.J.A.C. 5:21, the RSIS shall apply in addition to this section except to the extent the RSIS are superseded by this section or alternative standards applicable under a regional stormwater management plan or Water Quality Management Plan adopted in accordance with Department rules. (Ord. No. 2063-06 § 3) 25-29.4 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. 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). 161

DRAFT PROPOSED REVISIONS – OCTOBER 2011 c. The following linear development projects are exempt from the groundwater recharge, stormwater runoff quantity, and stormwater runoff quality requirements at subsection 25- 29.4f. 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 fourteen (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 at subsection 25-29.4f. 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 subsections 25-29.4f. and g. to the maximum extent practicable; 3. The applicant demonstrates that, in order to meet the requirements at subsection 25- 29.4f. 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 paragraph d,3. above within the upstream drainage area of the receiving stream, that would provide additional opportunities to mitigate for requirements of subsection 25-29.4f. and g. that were not achievable on-site. e. Nonstructural Stormwater Management Strategies. 1. To the maximum extent practicable, the standards in subsections 25-29.4f. and g. shall be

were not achievable on-site. e. Nonstructural Stormwater Management Strategies. 1. To the maximum extent practicable, the standards in subsections 25-29.4f. and g. shall be met by incorporating nonstructural stormwater management strategies at subsection 25-29.4e. 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 25-29.4e,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 measures 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 post- construction. "Time of concentration" is defined as the time it takes for runoff to 162

DRAFT PROPOSED REVISIONS – OCTOBER 2011 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. These source controls include, but are not limited to: (1) Site design features that help to prevent accumulation of trash and debris in drainage systems; (2) Site design features that help to prevent discharge of trash and debris from drainage systems; (3) Site design features that help to prevent and/or contain spills or other harmful accumulations of pollutants at industrial or commercial developments; and (4) 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. Any land area used as a nonstructural stormwater management measure to meet the performance standards in subsection 25-29.4f. 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. 4. Guidance for nonstructural stormwater management measures is available in the New Jersey Stormwater Best Management Practices Manual. The manual is available on the
