Design Criteria

Design storm return periods (years)

1-year, 2-year, 10-year, 100-year

“Ponds shall be designed for the 2 and 10-year storms; The 100-year storm should not overtop the embankment”
Dry Detention Ponds

Water quality volume method

Wet detention ponds: permanent pool volume equals 1 inch of runoff per impervious acre (0.5 inch for wet extended ponds with aquatic bench; 0.1 inch for micropool extended ponds). Dry detention lower stage detains the water quality volume for at least 24 hours.

“design permanent pool volume is equal to 1-inch of runoff per impervious acre on the site”
Wet Detention Ponds

Peak flow calculation method(s)

Hydrologic analysis for outlet structure sizing (water quality and quantity control)
