These steps include: • If the project has an approved WIHMP or equivalent, then any watershed specific criteria must be used and the project can evaluate participation in the approved regional or sub- regional opportunities. (Please ask your assigned planner or plan checker regarding whether your project is part of an approved WIHMP or equivalent.) • Determine applicable hydromodification control performance criteria. Refer to Section 7.II- 2.4.2.2 of the Model WQMP. • Determine applicable LID performance criteria. Refer to Section 7.II-2.4.3 of the Model WQMP. • Determine applicable treatment control BMP performance criteria. Refer to Section 7.II-3.2.2 of the Model WQMP. • Calculate the LID design storm capture volume for the project. Refer to Section 7.II-2.4.3 of the ModelWQMP.
