Determine the required area (in ft ) of a bioretention basin to service runoff from a shopping complex with 4 .2 acres of paved parking, 1.1 acre of sidewalks, 0.5 acre of landscaping. The 24-hr design storm is 1 inch. Use the empirical coefficients in Small Storm Hydrology method. There is no underdrain pipe for the bioretention basin. Use the following guidelines for the design: Ponding depth = 12 inch Media bed: 36 inches deep, porosity = 0.30 Gravel bed: 24 inches deep, porosity = 0.36

Question
Determine the required area (in ft ) of a bioretention basin to service runoff from a shopping complex with 4
.2 acres of paved parking,
1.1 acre of sidewalks,
0.5 acre of landscaping.
The 24-hr design storm is 1 inch. Use the empirical coefficients in Small Storm Hydrology method. There is no underdrain pipe for the bioretention basin. Use the following guidelines for the design:
Ponding depth = 12 inch
Media bed: 36 inches deep, porosity = 0.30
Gravel bed: 24 inches deep, porosity = 0.36
