5.3.5 Select BMPs for Flow Control

If MR #7: Flow Control is triggered, follow the steps listed in this section to select the appropriate Flow Control BMPs for a given project (or a TDA within the project). In addition, MR #5: On-site Stormwater Management and MR #6: Runoff Treatment may apply. See Vol II–5.3.3 Select BMPs for On-Site Stormwater Management and Vol II–5.3.4 Select BMPs for Runoff Treatment for additional information.

Step 1: Determine if Dispersion and Infiltration are Feasible

See Vol II–5.3.1 Determine Dispersion Feasibility and Vol II–5.3.2 Determine Infiltration Feasibility.

Step 2: Determine if Runoff Treatment requirements also apply

If MR #6: Runoff Treatment also applies, look for opportunities to use Flow Control BMPs that can also meet treatment requirements (see Vol II–5.4 BMP Design).

Step 3: Select Flow Control BMP(s)

Select a Flow Control BMP or multiple BMPs. Refer to Vol II–5.4 BMP Design for applicability, site suitability, and design criteria. Select Flow Control BMPs that best integrate with On-Site Stormwater Management and Runoff Treatment to the extent feasible.
