Habitat House

We are making a Habitat for Humanity house for the Shively family.  The family contains four people: Drew Shively- 30, Ladashe- 29, Zxavier- 8, Bob- 6.  Drew's family enjoys sporting events.  They also enjoy to hang out with their friends.  They like their car and their TV.  The want to have a Split Level house.  They want four bedrooms and three bath rooms.  The maximum square footage they can have is 1233 ft squared.  The would like to have some extra storage.  They would like to have few to no windows facing the prevailing winds.  They would also like to have their water heater close to their pluming fixtures.  They want to incorporate a large main room.

Storm Water Runoff

Pre-development Runoff

Q=CfCiA
Cf= 1.25
C= .1
i= 3.05
A= 0.5
(1.25)(.1)(3.05)(.05) = .2

Post development runoff

Drive Way

382.56+48.89+65.58+3.03+1273.94+126.02+8.70+8.70=1917.42〖ft〗^2
1917.42÷43560=0.044
A= .044
C= .825
i= 3.05
Cf= 1.25
0.04×.825×3.05×1.25= .126 
Q= .126 for drive way

House

A= 1120 / 43560= .026
C= .85
i= 3.05
Cf= 1.25
.026×.85×3.05×1.25=.084
Q= .084 for house

Site

A= .5- .044- .026= .43
C= .1
Cf= 1.25
i= 3.05
.43×.1×1.25×3.05=1.64
Q= 1.64 for site

.126 +.084 +1.64 = 1.85 
The site run off is 1.85

The difference in the runoff is 1.35 and I suggest a ditch would take care of this.
