From the Rhode Island Soil Erosion and Sediment Control Handbook:
Equation #1: for low density residential development (lot size greater than 1/4 acre). SV = [(76.6 x RA x TE) + (4.0 x DA x TE)] x T
Equation #2: for high density residential development (lot size less than or equal to 1/4 acre,
commercial or industrial land use.
SV = [(76.6 x RA x TED + (15.3 x DA x TE)) x T
where, SV = sediment volume (ft’)
RA = area of roadway and parking lots (acres)
TE = basin trap efficiency (80% standard)
DA = contributing land use area (acres)
T = time (years)
