1.3 Applicability of the Minimum Requirements and Additional Protective Measures

Not all of the Minimum Requirements apply to every new development or redevelopment project. The applicability varies depending on the type and size of the project. This section identifies thresholds that determine the applicability of the Minimum Requirements to different projects. The thresholds shall be determined using the proposed improvements for the entire project site.

Plat or short plat approval shall identify all stormwater BMPs that are required for each lot.

The Minimum Requirements shall be based on the most sensitive receiving waterbody along the discharge route. For determining which Minimum Requirements apply to a project, it shall be assumed that stormwater leaves the project site. Per Joint Administrative Policy and Procedure Directive No. 2021-02-001, Environmental Services/Site Development Group reserves the right to make the final determination of the applicability of the Minimum Requirements.

The flowcharts in Figure 1 - 1 to Figure 1 - 3 are intended as guidance for determining Minimum Requirements. The figures do not provide a complete analysis of each Minimum Requirement. The applicant must review Section 1.3.4 - New Development, Section 1.3.5 - Redevelopment and the text of each Minimum Requirement to determine stormwater mitigation requirements for their project. The written text shall take precedence over the flowcharts.
