It is not practical to show all possible stormwater design standards
in this section. Therefore, standards from the following references
shall be considered in the planning and design of all stormwater management
systems affecting County highways, bridges, drainageways, and related
structures and facilities.
A. Residential Site Improvement Standards of the New Jersey (Chapter
7) Administrative Code, Title 5, Chapter 21, except where modified by the County. (Note: Where reference is made to approvals by the municipal engineer, a municipal agency, municipal attorney, or similar reference, it shall mean the County Engineer, County agency, County Counsel, etc.)
B. Construction practices shall conform to Standards for Soil Erosion
and Sediment Control in New Jersey, N.J.A.C. 2:90-1, as administered
by the New Jersey Department of Agriculture.
C. Highway drainage structures shall be designed, where applicable,
in accordance with the Design Manual-Roadway, New Jersey Department
of Transportation.
D. Inlets, catch basins, and manholes shall be designed in accordance
with the Standard Specifications for Road and Bridge Construction,
New Jersey Department of Transportation.
E. Urban Hydrology for Small Watersheds, Technical Release No. 55 (TR-55),
U.S. Department of Agriculture, Soil Conservation Service, Engineering
Division.
F. Design and Construction of Urban Stormwater Management Systems, ASCE
Manuals and Reports of Engineering Practice No. 77.
G. Green Infrastructure Guidance Manual for New Jersey, Rutgers Cooperative
Extension Water Resources Program.
In addition to the standards of the County, the stormwater management
facilities in the Pinelands Area shall be designed to comply with
the requirements and standards of the New Jersey Pinelands Comprehensive
Management Plan, as administered by the Pinelands Commission.
A. Drainage calculations shall be provided which demonstrate conformance
with the standards of N.J.A.C. 7:50-6.84 of the Comprehensive Management
Plan and describe any deviations from County standards.
B. In any Pinelands Area, no development within wetlands or within 300
feet of wetlands is permitted unless the developer can demonstrate
that the development will not result in an adverse impact on wetland
areas as determined by the Pinelands Commission.
Prior to final approval being issued, the applicant shall provide
the following:
A. A construction cost estimate for the stormwater management facilities
approved by the DRC. If additional construction is proposed, as part
of the approval process, these costs shall be combined into one cost
estimate.
B. A performance guarantee in the amount of the cost estimate approved
by the County.
A drainage covenant may be required by the DRC if a County road
or drainage facility is incorporated into the stormwater management
plan of a site plan or subdivision application. The drainage covenant
shall conform to the Declaration of Covenants and Restrictions for
Drainage Structures found on the County website.
