Policy statement. Flood control, groundwater recharge, and pollutant
reduction shall be achieved through the use of stormwater management
measures, including green infrastructure Best Management Practices
(GI BMPs) and nonstructural stormwater management strategies. GI BMPs
and low impact development (LID) should be utilized to meet the goal
of maintaining natural hydrology to reduce stormwater runoff volume,
reduce erosion, encourage infiltration and groundwater recharge, and
reduce pollution. GI BMPs and LID 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.
Purpose. The purpose of this chapter is to establish minimum stormwater management requirements and controls for "major development," as defined below in § 396-3.
An application required by ordinance pursuant to Subsection C(1)(b) above that has been submitted prior to April 24, 2024, shall be subject to the stormwater management requirements in effect on April 23, 2024.
An application required by ordinance for approval pursuant to Subsection C(1)(b) above that has been submitted on or after March 2, 2021, but prior to April 24, 2024 shall be subject to the stormwater management requirements in effect on April 23, 2024.
Notwithstanding
any rule to the contrary, a major development for any public roadway
or railroad project conducted by a public transportation entity that
has determined a preferred alternative or reached an equivalent milestone
before July 17, 2023, shall be subject to the stormwater management
requirements in effect prior to July 17, 2023.
Compatibility with other permit and ordinance requirements. Development
approvals issued pursuant to this chapter are to be considered an
integral part of development approvals 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 chapter
shall be held to be the minimum requirements for the promotion of
the public health, safety, and general welfare. This chapter is not
intended to interfere with, abrogate, or annul any other ordinances,
rule or regulation, statute, or other provision of law except that,
where any provision of this chapter 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.
