A hydrologic analysis was performed on two tracts of land (0.4995 acre and 0 .5765 acre respectively) located in the Richard Carter League, Abstract No. 8, College Station, Texas, consisting of a total of 1.076 acre of land . The objective of this report is to document the drainage impacts prior to and subsequent to the development of the property. This drainage report has been prepared in accordance with current City drainage design standards . A drainage map accompanying this report illustrates the configuration and topography of the site . The lot to the south (the larger tract) is currently the site of College Hills Missionary Baptist Church. The owner is proposing to develop a parking lot both tracts of land. After the parking lot is built , there will be either pavement or structures covering most of the land . The site sits in an older area of the community known as College Hills . The north tract is currently undeveloped land with native grass cover and no trees. The land slopes generally toward the southeast at 1. 8 percent. The south tract is contains the church building which, when combined with the sidewalks, covers approximately 22 percent of the tract. The subject tract does not lie within a designated 100 year flood plain according to FEMA maps. Methodology The rational method was used to compute the 5, 10 , 25 , 50, and 100 year storm events in accordance with City drainage design standards. The rational formula is expressed as: where Q = c = I = A = Q=CIA peak discharge in cubic feet per second (cfs) runoff coefficient rainfall intensity in inches per hour (1) land area in acres that contributes stormwater runoff that passes through or at a designated design point. Table 1 presents a summary of storm runoff calculations for each area within the subject tract. Under predevelopment conditions the 100 year peak runoff rate is 5.60 cfs. With the construction of the parking lot , postdevelopment peak runoff rate will be 12.09 cfs . Refer to Table 2.
