Site Map of Drainage Basin I
scale 1" = 50'
CALCULATIONS:
1. Determine storage volume required (use runoff coefficient)
Rv = 0.05 + .009(I) where I = site area/total site area
Assumption: divide east and west projects @ high point of roadway
Impervious site of drainage basin "I" = 36,371 sq. ft.
I = 36,371/39,948 = .91
Rv = .05 + .009(.91) = .87
Volume = .87(39,948) x 1.5/12 DENR Requirement = 4,344 cu.ft
2. Determine Volume required for Emerald Isle
Volume =L- .87(39,948) x 2/12 = 5,792 cu. ft
3. Determine Volume Provided
Trench size = 4.3 (height) x 23 (width) = 98.9 sq. ft
There are three pipes (36" dia) inside trench, therefore pi(r)(r) for 3' pipe = 7.06 sq.ft.
Volume = 98.9 sq. ft - 21.2 sq. ft = 77.7 sq. ft
and this represents the voids with, so multiply by 0.35 & 77.7 x .35 = 27.2 sq. ft,
add area of pipes = 21.1 sq. ft.
Total area = 48.3 sq. ft
Therefore 5,792/48.3 = 120 feet. Use 125 foot long trench.
Benchmark Note: The building slab is set at + 15.2' (msl)
Sidewalk Notes for East Building
The sidewalk on the south side of the building = 10 feet wide
The sidewalk on the north side of the building = 3 feet wide
The sidewalk on the east side of the building = 5 feet wide

Rv = 0.05 + .009(I) where I = site area/total site area Width of Parking Lot = 160'

I = 19,2$8/29,309 = 0.66 Width Of Parking Lot = 170'
Rv = .05 + .009(.66} _ .64 Length of Parking Spaces = 20'
Area between parking spaces = 25'
Volume = .64(29,309) x 1.5/12 = DENR Requirement = 2,344 cubic feet
2. Determine Volume required for Emerald Isle Service Road Width between buildings = 25'
Volume = .64(29,309) x 2/12 = 3,126 cubic feet
3. Determine Volume Provided
Trench size = 3.5'(height) x 15'(width) = 52.5 square feet
There are two pipes (36" dia) inside trench, therefore pi(r)(r) for 3' pipe = 7.06 sq. ft.
Volume = 52.5 sq. ft. - 14.1 = 38.4 sq. ft.
and this represents the voids, so multiply by 0.35 and .35(38.4) = 13.44 sq. ft.
add area of pipes = 14.1 sq. ft.
Total area = 27.5 sq. ft.
Therefore 3,126/27.5 = 114 feet Use 120 foot long trench

CALCULATIONS:
1. Determine storage volume required (use runoff coefficient)
Rv = 0.05 + .009(I) where I = site area/total site area
Drainage Basin "III" area = 6,460 sq. ft
Impervious site of drainage basin III = 6,029 sq. ft
I = 6,029/6,460 = .93
Rv = .05 + .009(93) = .89
Volume = .89(6,460) x 1.5/12 = DENR Requirement = 719 cubic feet
2. Determine Volume required for Emerald Isle
Volume = .89(6,460) x 2/12 = 958 cubic feet
3. Determine Volume Provided
Trench size = 2.5'(height) x 12'(width) = 30 square feet
There is a single pipe (30" dia.) therefore pi(1.25)(1.25) for 30" pipe = 4.9 sq. ft
Volume of trench = 30 sq. ft - 4.9 = 25.1 sq. ft
and this represents the voids, so multiply by 0.35 and .35(25.1) = 8.8 sq.ft
area of pipe = 4.9 sq. ft
total volume = 13.7 sq. ft
Therefore 958/13.7 = 69.9 feet so use a 70 foot long section

CALCULATIONS:
10
CID 1. Determine storage volume required (use runoff coefficient)
Rv = 0.05 + .009(I) where I = site area/total site area
Drainage area "IV" = 10,737 sq. ft
Impervious portion of "IV" = 10,308 sq. ft
I = 10,308/10,737 = .96
Rv = .05 + .009(96) = .91
�Volume = .91(10,737) x 1.5/12 = DENR Requirement = 1,221 cubic feet
2. Determine Volume required for Emerald Isle
Volume = .91(10,737) x 2/12 = 1,628 cubic feet
3. Determine Volume Provided
Trench size = 2.5'(height) x 22'(width) = 55 square feet
(� The pipe diameter is 24" so the area of the pipe is pi(r)(r) or 3.14. 3 pipes = 9,42 sq. ft
The volume of the trench = 55 sq. ft - 9.42 sq. ft = 45.6 sq. ft
and this represents the voids, so multiply by .35(45.6) = 15.9 sq. ft
o area of the pipes = 9.42 sq. ft
0 total area = 25.3 sq. ft
Therefore 1,628/25.3 = 64.3 feet, so use a 65 foot long trench section
