Following the calculation of pre- and post-development (or increase in development) stormwater runoff, if 100% of this increased storm water will not be retained on-site in a stormwater retention basin, the storm water management plan shall be prepared by a registered professional as defined by this chapter. The agent may waive this requirement for regulated activities on a single family dwelling site when the agent finds that, considering the size, location, or natural discharge of the stormwater runoff, a storm water management plan is not reasonably required to accomplish the objectives of this chapter.
