Provisions shall be made for the drainage of surface runoff waters in and from the premises so that flooding and erosion of the property and the property of others shall be prevented.
(2) 
Soil erosion and sediment control and stormwater management plans must coordinate with all other applicable ordinances, statutes and governmental agency requirements, including but not limited to Soil Conservation Service, Army Corps of Engineers, the New Jersey Department of Environmental Protection and the United States Environmental Protection Agency.
(3) 
The following principles shall govern the preparation of all applications and guide the approving authority in its consideration of same:
(a) 
Vegetation.
[1] 
The practical philosophy regarding sediment control is to arrest it at the earliest possible stage and retain it on the construction site. The susceptibility of the land to erosion shall be minimized during and after development.
[2] 
The smallest practical area of soil shall be exposed at any one time. As the use of natural cover is an effective method of limiting erosion and stormwater runoff, existing natural vegetation shall be protected and preserved to the maximum extent possible.
[3] 
Temporary plant cover and/or effective mulching shall be used to protect critical erosion areas during development. Temporary vegetative cover shall be such as to perpetuate itself until permanent vegetation is provided. Vegetative cover shall be established as early during development as possible.
[4] 
Specifications for both temporary and permanent seeding shall be prepared and submitted. Permanent measures for soil erosion and stormwater management, including seeding and/or sodding of grass waterways, shall be completed before beginning any other land disturbance or construction.
(b) 
Nonvegetation. To intercept sediment and debris in runoff water during development, nonvegetative measures such as stone filter berms, brush barriers, staked straw bale barriers, sediment basins or silt traps shall be installed and maintained. Maintenance for all nonvegetation shall be subject to § 149-49 herein.
(c) 
Excavation.
[1] 
The manner and sequence in which excavation takes place can strongly affect the success of the soil erosion and sediment control plan.
[2] 
Excavated material shall not be spilled or dumped into streams, watercourses, wetlands or stream buffers or placed in such a manner that it will easily erode into them.
[3] 
Stream buffers shall remain in their natural vegetative state, undisturbed, except as provided herein, and shall not be used for storage or parking of equipment and automobiles.
[4] 
Depressions and pits shall not be created. Lateral support of abutting roads and properties shall be provided.
[5] 
Except for excessive amounts of topsoil, no topsoil shall be removed from the site. No topsoil shall be used as spoil.
[6] 
Topsoil moved during the course of development shall be redistributed so as to provide at least six inches of cover to all disturbed areas of the development and shall be stabilized by seeding or plantings.
(d) 
Drainage patterns.
[1] 
Wherever possible, streams, watercourses and wetlands and their stream buffers shall be preserved, and interruption or impediment of natural drainage entering or leaving the property shall be minimized.
[2] 
Maximum use shall be made of presently existing surface water runoff control devices, mechanisms or areas such as existing berms, terraces, streams, grass waterways, favorable hydrologic soils, swales, watercourses, woodlands, floodplains and wetlands as well as any proposed retention/detention structures.
[3] 
Due consideration shall be given to the relationship of the subject property to the natural or established drainage pattern of the subwatershed of which it is a part.
[4] 
Surface water runoff shall not be transferred from one watershed to another by artificial means.
[5] 
Evaluation shall be made of the characteristics of the subwatershed of which the development is a part and the receiving stream capacities.
[6] 
Streams, watercourses and wetlands which normally carry or receive surface water runoff shall not be overloaded with increased runoff, sediment or other pollution during or after development.
[7] 
Any changes in the contours of the land from its natural state or any structures, diversions or other improvement shall not introduce into any stream, watercourse, wetland or aquifer recharge area any pollutant, whether from a point or nonpoint source, discharge or sediment load which would affect the stability or ecological balance of the streams, watercourses, wetlands or aquifer recharge areas by either pollution or any increase or decrease of the natural flows.
(e) 
Groundwater recharge. The ability to retain and maximize the groundwater recharge capacity of the area being developed is encouraged. Design of the stormwater runoff control system shall give consideration to providing groundwater recharge to compensate for the reduction in the percolation that occurs due to the increase in impervious surface areas.
(f) 
Drainage facilities.
[1] 
All water-carrying structures and/or retention/detention areas shall be completed and stabilized prior to diversion of water to them.
[2] 
Temporary drainage facilities shall be provided to accommodate water runoff during the construction of permanent drainage facilities.
[3] 
Where development of a property presents the threat of flooding or damage by flash runoff to downstream areas, the facilities for stormwater runoff control shall be constructed prior to any earthmoving or drainage construction of the development.
[4] 
To the greatest possible extent, the plan shall avoid the concentration of flow and shall provide for dissipation of velocities at all concentrated discharge points.
[5] 
Stormwater runoff from roads and structures shall have suitable retention or pollution controls to minimize pollution and runoff entering a stream, watercourse, wetland or aquifer recharge area.
[6] 
Where drainage swales are provided, they shall be constructed to afford a minimum amount of land disturbance. They should be placed between trees with a minimum side clearance of disturbance. They should follow natural drainage courses and contours.
B. 
Drainage design standards.
(1) 
The drainage systems shall be designed in conformance with accepted engineering standards. A report on storm drainage calculations shall be prepared, signed and sealed by a licensed professional engineer in the State of New Jersey, in sufficient detail for a review of these calculations. Includes shall be maps, plats or other materials necessary to establish areas tributary to the site as well as areas within the site tributary to a specific drainage structure, methodology for selection of various variables and capacity of proposed systems.
