Relationship to state manual

adopts state manual directly

“the peak rate of runoff and volume of runoff increase. These effects are caused by 1) a reduction in the opportunity for infiltration, evaporation, transpiration, and depression storage; 2) an increase in the amount of imperviousness; and 3) modification of the surfac”
p. 7

Water quality volume method

Capture and treat a water quality volume typically equal to the first 1 inch or first 1.5 inches of rainfall, sized with Schueler's Simple Method (Appendix A). Recommended BMP-specific treatment volumes include: wet detention — first 0.5 inch of runoff or 1.5 inches from impervious area; dry retention and constructed wetlands — first 1.0 inch of runoff or 2.5 inches from impervious area (whichever is greater for dry retention).

“first 1 inch or first 1.5 inches of rainfall... Schueler's Simple Method”
