The proposed structure will cover 2884 sq. ft. with an additional 520 sq. ft, of semi- pervious driveways. The total site covers 7200sq. ft. Soils in this area are generally classified as part of the Chipley -Urban Land Complex. This site was covered by approximately 4 feet of fill about 20 years ago. No recent soil analysis has been made. Flow Calculation Basis The runoff for this site was calculated using the Rational Method as per the "State of Georgia Green Book ". Storm Water Disposition, Storm waters will be directed to the existing retention area located 150 feet to the rear of this property. A small depressed area at the front (south side) of the property will continue to drain into the existing curb inlet which discharges into the retention pond. Summary Pre - development runoff Post - development runoff Increased run off Runoff to curbed inlet Runoff to retention area Velocity in swales = .38cfs, = .66cfs. = .28cfs. _ .20 cfs. .46 cfs. =..-p fps. Note: The property owners association has found it necessary to install a shallow well and pwnp to maintain a minimal water level in the (retention) holding pond located north of this property. Increased runoff should help maintain a minimal water level. xlo"iiz ` SW €I" 66trJy? ,.U;1/ Cr.—`4 1, ree r%r r-W7o 1 zG,.. �' KR1-r . r{iirGFia►'/�/ztirl�ct %%/ t" w /.+ • /or 4r = ?zoo 4-14 . /6 54 /ryrpe rvioz 2884 -r(z . ote A S�"77i(?ar'V/o4 -5201/2 .t //e Pei- +--,eDus — Sr96 C-Tz - . 0884 /654 C„a pry /ouS .35 Cw poi = •066 X,95 f •0 /(X,5 ,088x.315: .6C QPrcai;c sr.35x6.59k./65 =3 &c{S Qpos{ = . 5 x.38 _ t6 ce increase = . 08 c�S. tsc /5- A;//p5 /7 / ex ./; r`J 5r -Qde C 5 Sho( t)1,7, Zo�r o'Aa40' Pfdpasad f,eo r 2OX8o Z X /5xso 2Z /Alm - ,r,y S�-G " /air A -4 o 4/F7d 11 x Suiczie /600 COO Zoo
