Flood control, groundwater recharge, and pollutant reduction
through nonstructural or low-impact techniques shall be explored before
relying on structural best management practices (BMPs). Structural
BMPs should be integrated with nonstructural stormwater management
strategies and proper maintenance plans. Nonstructural strategies
include both environmentally sensitive site design and source controls
that prevent pollutants from being placed on the site or from being
exposed to stormwater. Source control plans should be developed based
upon physical site conditions and the origin, nature, and the anticipated
quantity or amount of potential pollutants. Multiple stormwater management
BMPs may be necessary to achieve the established performance standards
for water quality, quantity, and groundwater recharge.
It is the purpose of this Part
2 to establish minimum stormwater management requirements and controls for major development, as defined in Article
XII.
Development approvals issued for subdivisions and site plans
pursuant to this Part 2 are to be considered an integral part of development
approvals under the subdivision and site plan review process and do
not relieve the applicant of the responsibility to secure required
permits or approvals for activities regulated by any other applicable
code, rule, act, or ordinance. In their interpretation and application,
the provisions of this Part 2 shall be held to be the minimum requirements
for the promotion of the public health, safety, and general welfare.
This Part 2 is not intended to interfere with, abrogate, or annual
any other ordinance, rule or regulations, statute, or other provision
of law except that, where any provision of this Part 2 imposes restrictions
different from those imposed by any other ordinance, rule or regulation,
or other provision of law, the more restrictive provisions or higher
standards shall control.
