OCTOBER 29, 1990 DRAINAGE REPORT CAMPUS WEST TEXACO The Campus West Texaco station is located at 1015 South Shields Street, which is on the west side of Shields about 200 feet south of Elizabeth Street. The total area of the site is 26400 square feet, 19404 square feet of which is pavement or buildings, and 6204 square feet is gravel surfaced, and 792 square feet is dirt. There are 21780 square feet of the existing site draining to Shields Street, and 4620 square feet of the site drains west to the John 23rd University Center Church site.' The quantities of existing runoff are calculated on sheet 2 of this report. The portion of the church site which receives runoff from Campus West Texaco is a parking lot and green area which acts as a large detention pond due to its limited outflow through an old subdrain. We propose to construct a detention pond on the west part of the Campus West Texaco which will have a restricted outflow into the church site. The proposed new plan will require paving of 6204 square feet of existing gravel surface, and the required detention volume is the difference in total runoff between the paved and gravel surface, based on a 100 year 3 hour storm. The volume is calculated on sheet 3 of this report. The outflow from the detention pond into the church site is 0.08 c.f.s., which is the existing 2 year ruoff. The sizing of the outflow pipe is calculated on sheet 3 of this report. PhiPhi l� Robinson, P.E. & L.S. 1 o F 4- ti COMPUTATIONS., Stewart & Associates, Inc. _ 214 N..Howes..St' • Ft.
