The AHJ may issue a storm water discharge permit that waives storm water management requirements. Variation from these requirements shall require the written approval of the AHJ, whose actions shall be conditioned upon the following:
(A) The AHJ has determined that the overall storm water management for drainage system is best suited to allow the site to drain unrestricted so that the timing of the discharge will not adversely impact upstream lands;
(B) The owner/developer shall provide evidence in writing outlining in detail the rationale for the proposed design changes including hydraulic and or hydrologic computations. This document must be signed and sealed by a licensed professional engineer; and
(C) Granting of the variance will not be detrimental to the public health, safety or welfare, or injurious to other property in the territory in which said property is located.
