Watershed location plays an important role in identifying how the Stormwater Regulations, specifically the Post‑Construction Stormwater Management Requirements, are applied to a project. Once the location of the development site is determined, Appendix D may be used to evaluate its Flood Management District and sewer service area. If they are unable to confirm either, the applicant should contact Stormwater Plan Review. These maps are approximations of sewershed boundaries. The applicant must refer to their project’s point of stormwater discharge when determining which requirements apply to their project.
