Link to this table
|MIDS Stormwater Pond Design Level1||Permanent Pool Volume (Vpp), ft3||Water Quality Volume (Vwq), ft3||Pollutant reduction (%)2|
|Design Level 1||≥ 1,800 ft3 per acre of tributary area||<= 1 inch from impervious area||60||34||62||0|
|Design Level 2||<= 1 inch from impervious area||84||50||84||8|
|Design Level 3||<= 1.5 inch from impervious area||90||60||90||23|
1From MIDS Calculator documentation for stormwater ponds. Note: the table summarizes design-level criteria related to permanent pool volume and water quality volume. The complete list of criteria for each design level is summarized on the MIDS calculator
website linked above.
2 TSS = total suspended solids; TP = total phosphorus; PP = particulate phosphorus; and DP = dissolved phosphorus. Pollutant reduction values cited assume no upstream treatment within tributary area to pond (i.e., untreated urban runoff).
