Design Criteria

Design storm return periods (years)

1-year, 2-year, 5-year, 10-year, 25-year, 50-year

“the post-construction peak stormwater discharge rate must be reduced to no greater than the pre-construction peak stormwater discharge rate (usually for the 2-year, 24-hour storm).”
Chapter 1, Comparison of BMP Treatment Capabilities

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).

“There will be a volume of stormwater that must be captured and treated prior to release (typically first 1 inch or first 1.5 inches of rainfall).”
Chapter 1, Comparison of BMP Treatment Capabilities

Peak flow calculation method(s)

SCS Runoff Curve Number Method, Short Cut Floodrouting Method (detention storage within method limits)

“Runoff volumes and rates may be calculated using the SCS Runoff Curve Number Method (see Appendix Volume, Appendix A, A-16).”
