[Amended 5-24-2006 by Ord. No. 2006-003; 2-17-2021 by Ord. No. 2021-005]
All terms in this section shall be defined in the NJDEP Stormwater Rule (N.J.A.C. 7:8, et seq.). The following additional terms are defined for this chapter only.
EXEMPT DEVELOPMENT
Any development that creates an increase of less than 500 square feet of impervious area and disturbs less than 2,500 square feet of land. Further, an exempt development shall not meet the definition of "minor development."
MAJOR DEVELOPMENT
A. 
Any individual development, as well as multiple developments that individually or collectively result in:
(1) 
The disturbance of one or more acres of land since February 2, 2004;
(2) 
The creation of one-quarter acre or more of regulated impervious surface since February 2, 2004;
(3) 
The creation of 1/4 acre or more of regulated motor vehicle surface since March 2,2021; or
(4) 
A combination of the items in Subsection A(2) and (3) above that totals an area of 1/4 acre or more. The same surface shall not be counted twice when determining if the combination area equals 1/4 acre or more.
B. 
Major development includes all developments that are part of a common plan of development or sale (for example, phased residential development) that collectively or individually meet any one or more of conditions in Subsection A(1), (2), (3), or (4) above. Projects undertaken by any government agency that otherwise meet the definition of “major development” but which do not require approval under the Municipal Land Use Law, N.J.S.A. 40:55D-1 et seq., are also considered “major development.”
MINOR DEVELOPMENT
Any development that results in the creation of an increase of 500 square feet or more of impervious area or one that disturbs more than 2,500 square feet of land area. Further, a minor development shall not meet the definition of "major development."
A. 
Exempt developments. Any project meeting the definition of "exempt development" shall be exempt from the provisions of this section.
B. 
Minor developments. Minor developments shall be designed to include the following stormwater management measures:
(1) 
Water quality. Soil erosion and sediment control measures shall be installed in accordance with the Standards for Soil Erosion and Sediment Control in New Jersey.
(2) 
Rate/volume control. Seepage pits or other infiltration measures shall be provided with a capacity of three inches of runoff for each square foot of new impervious area. Stone used in the infiltration devices shall be 2 1/2 inches clean stone and design void ratio of 33% shall be used. The infiltration measures shall be designed with an overflow to the surface which shall be stabilized and directed to an existing stormwater conveyance system or in a manner to keep the overflow on the developed property to the greatest extent feasible. If the new impervious surface is not roof area, an equivalent area of existing roof may be directed to the infiltration system. This shall be permitted where the existing roof is not already directed to infiltration devices.
C. 
Major developments. All major developments shall have their stormwater management designed in accordance with the Residential Site Improvement Standards (RSIS, N.J.A.C. 5:21) and the NJDEP Stormwater Rule (N.J.A.C. 7:8). These standards shall apply to all projects, residential and nonresidential as well as projects by the Township, Board of Education and other agencies subject to review by the Township.
A. 
Standards for relief. Waivers from strict compliance with the major development design standards shall only be granted upon showing that meeting the standards would result in an exceptional hardship on the applicant or that the benefits to the public good of the deviation from the standards would outweigh any detriments of the deviation. A hardship will not be considered to exist if reasonable reductions in the scope of the project would eliminate the noncompliance.
B. 
Mitigation. If the reviewing agency for the project determines that a waiver is appropriate, the applicant must execute a mitigation plan. The scope of the mitigation plan shall be commensurate with the size of the project and the magnitude of the relief required. The mitigation project may be taken from the list of projects in the Municipal Stormwater Management Plan. All mitigation projects are subject to the approval of the Township Engineer.
C. 
Reviewing agency. All applications subject to the review of the Land Use Board shall be reviewed by the Board concurrently with subdivision or site plan review. Applications not subject to Land Use Board review shall be reviewed by the Township Engineer.
D. 
Appeals. The appeal of the determination of the Township Engineer shall be made in accordance with N.J.S.A. 40:55D-70a.
There shall be no additional fees for stormwater review for applications to the Land Use Board. Minor development applications to the Township Engineer shall be accompanied by a review fee in the amount of $250. Major development applications shall be accompanied by a review fee in the amount of $1,000. If a project is approved, an inspection escrow deposit shall be made in an amount to be determined by the Township Engineer.
A. 
Applicability. Projects subject to review as in § 470-73 of this chapter shall comply with the requirements of § 470-77B and C.
B. 
General maintenance.
(1) 
The design engineer shall prepare a maintenance plan for the stormwater management measures incorporated into the design of a major development.
(2) 
The maintenance plan shall contain specific preventative maintenance tasks and schedules; cost estimates, including estimated cost of sediment, debris, or trash removal; and the name, address, and telephone number of the person or persons responsible for preventative and corrective maintenance (including replacement). Maintenance guidelines for stormwater management measures are available in the New Jersey Stormwater Best Management Practices Manual. If the maintenance plan identifies a person other than the developer (for example, a public agency or homeowners' association) as having the responsibility for maintenance, the plan shall include documentation of such person's agreement to assume this responsibility, or of the developer's obligation to dedicate a stormwater management facility to such person under an applicable ordinance or regulation.
(3) 
Responsibility for maintenance shall not be assigned or transferred to the owner or tenant of an individual property in a residential development or project, unless such owner or tenant owns or leases the entire residential development or project.
(4) 
If the person responsible for maintenance identified under § 470-77B(2) above is not a public agency, the maintenance plan and any future revisions based on § 470-77B(7) below shall be recorded upon the deed of record for each property on which the maintenance described in the maintenance plan must be undertaken.
(5) 
Preventative and corrective maintenance shall be performed to maintain the function of the stormwater management measure, including repairs or replacement to the structure; removal of sediment, debris, or trash; restoration of eroded areas; snow and ice removal; fence repair or replacement; restoration of vegetation; and repair or replacement of nonvegetated linings.
(6) 
The person responsible for maintenance identified under § 470-77B(2) above shall maintain a detailed log of all preventative and corrective maintenance for the structural stormwater management measures incorporated into the design of the development, including a record of all inspections and copies of all maintenance-related work orders.
(7) 
The person responsible for maintenance identified under § 470-77B(2) above shall evaluate the effectiveness of the maintenance plan at least once per year and adjust the plan and the deed as needed.
(8) 
The person responsible for maintenance identified under § 470-77B(2) above shall retain and make available, upon request by any public entity with administrative, health, environmental, or safety authority over the site, the maintenance plan and the documentation required by § 470-77B(6) and (7) above.
(9) 
The requirements of § 470-77B(3) and (4) do not apply to stormwater management facilities that are dedicated to and accepted by the municipality or another governmental agency.
(10) 
In the event that the stormwater management facility becomes a danger to public safety or public health, or if it is in need of maintenance or repair, the municipality shall so notify the responsible person in writing. Upon receipt of that notice, the responsible person shall have 14 days to effect maintenance and repair of the facility in a manner that is approved by the Municipal Engineer or his designee. The municipality, in its discretion, may extend the time allowed for effecting maintenance and repair for good cause. If the responsible person fails or refuses to perform such maintenance and repair, the municipality or county may immediately proceed to do so and shall bill the cost thereof to the responsible person.
C. 
Nothing in this section shall preclude the municipality in which the major development is located from requiring the posting of a performance or maintenance guarantee in accordance with N.J.S.A. 40:55D-53.
Any person who erects, constructs, alters, repairs, converts, maintains, or uses any building, structure or land in violation of this chapter shall be subject to one or more of the following penalties: imprisonment for a term not exceeding 90 days; a fine not exceeding $2,000; and a period of community service not to exceed 90 days.
This chapter shall take effect March 2, 2021.
