Introduction
These calculations are being provided to properly size the storm drainage proposed to be constricted as shown on the
attached plan, at the Lawrence Municipal Airport, North Andover, Massachusetts,
AREA 1 to Catch Basin 1
Total watershed area = 0.32 acres
Impervious area®C of 0.90 = 91 90
Lawn area®C of 0.10 = 9 %
Composite C = 0.83•
Maximum hydraulic length = 140 ft
Average slope = 0.016 ft/ft
TR55 Sheet flow over pavement = 2 minutes(use Boston I-D-F chart minimum of 5 minutes)
5 year-5 minute rainfall intensity = 4.9 inches/hour
Peak runoff rate = (0.83) (4.9 inches/hour) (0.32 acres) = 1.3 cfs
AREA 2 to Catch Basin 2
Total watershed area = 0.71 acres
Impervious area®C of 0.90 = 84 %
Lawry area @ C of 0.10 = 16 %
Composite C = 0.77
Maximum hydraulic length = 210 ft
Average slope = 0.014 ft/ft
TR55 Sheet flow over pavement = 2 minutes (use Boston I-D-F chart minimum of 5 minutes)
5 year-5 minute rainfall intensity = 4.9 inches/hour
Peak runoff rate = (0.77) (4.9 inches hour) (0.71 acres) = 2.7 cfs
AREA 3 to Catch Basin 3
