A.
For any
development site, the developer has the option of discharging post-development
runoff at a higher rate than pre-development runoff if the developer
can prove that no harm would be caused to any person or property located
upstream or downstream of the development site. The developer must
assume that the entire subarea in which the site is located is developed.
The type and amount of development that the developer must consider
shall be either based on current zoning or established by the Township,
whichever results in a greater amount of imperviousness. Proof of
no harm must demonstrate conformance with the hydraulic capacity criteria
specified in this chapter. Areas that drain through documented drainage
problem areas would be precluded from any no harm based peak runoff
increases, except where hydraulic capacity improvements would be provided,
consistent with this chapter.
B.
A "no harm analysis" must be submitted as part of a stormwater management
plan and report package.
