Jimmerson: Attached are 2 copies of the revised site plan and erosion control plan for the proposed temporary parking lot for the Christ United Methodist Church facility. A drainage swale/berm has been added to the plans to direct the storm water runoff from the proposed parking to the existing drainage prior to where it leaves the Church property.

' Addendum to Drainage Report for Christ United Methodist Church 4203 State Highway 6 South College Station, Te x as September 1999 Prepared by : Joseph P. Schultz , P.E. 1707 Graham Road College Station, Texas 77845 ' . .. Introduction The drainage report for the Christ United Methodist Church was submitted and approved in October 1997. The original report was prepared by Michael G . Hester, P.E. of the Hester Engineering Company. This report presented the proposed on-site drainage improvements and the anticipated downstream effects of these improvements. No detention facility was proposed for this site and it was shown that the increases in the stormwater runoff and depth in the downstream drainage channels was minimal. This addendum to the report will present the proposed changes to the project site and how it will affect the stom1water runoff. Drainage Basin Modifications A 180 car, temporary parking lot is proposed for an undeveloped portion of land northwest of the existing church . The proposed parking lot will be 1.3 acres in size and be surfaced with crushed limestone base material. The stormwater runoff will be increased due to the impervious characteristics of the parking lot surface. The Rational Equation runoff coefficient "C" will increase for the 1 .3 acres from 0.45 to 0.90. The drainage report calculated the peak runoff at three locations for comparison between the pre-development and post-development conditions. The cumulative drainage areas at these locations were 10.9 acres, 31.0 acres, and 39.1 acres. The drainage areas, Time of Concentration, Tc, and the rainfall intensities used in the original report will be used in computing the increase in the peak runoff rates due to the addition of the temporary parking lot. Table 1 presents a summary of the peak runoff rates for the 100-year storm. Table 1 -Comparison of 100-year Storm Peak Runoff Post Development, w / Pre-Development Post-Development Parking Lot Composite Runoff Composite Runoff Composite Runoff Area "C" Q, cfs "C" Q, cfs "C" Q, cfs -- 10.9 Ac. 0.503 47.9 0.583 58.0 0 .641 63.3 31.0 Ac. 0.508 143.5 0.538 157.8 0.557 163.3 34.1 Ac. 0.503 149.7 0 .530 163.6 0.547 168.9 The drainage report compared the pre-development runoff to the post-development runoff conditions by computing the depth of flow in the existing drainage ditch from the property site to Lick Creek. The HEC-RAS computer model program was used to determine the depth of flow in the existing ditch. The development of the site resulted in the depth of water in the existing ditch increasing by 0.02 to 0.08' in depth. The construction of the parking lot will increase the peak runoff rate for the 100-year storm in the existing ditch by 5.5 cfs. This will increase the depth of flow in the ditch by an additional 0.01 to 0.04'. The maximum depth increase due to the existing church facility and proposed parking lot will be 0 .12'. ' . . ... A comparison was also made of the pre-development and post-development conditions in Lick Creek at its confluence with the existing drainage. The elevation of the water surface in Lick Creek for the 100-year storm event increased from 270.00 to 270.07 due to the construction of the church facility . This was due to a 13 .9 cfs increase in the peak runoff at this location . The construction of the temporary parking lot will result in an additional increase in the peak runoff rate of 5.5 cfs . The 100 yr water surface in Lick Creek will rise from 270.07 to 270 .10 due to this increase. Conclusions The construction of the temporary parking lot will increase the stormwater runoff from the project site and increase the depth of flow in the downstream drainage ditch and Lick Creek. However, these increases are minimal and will result in little, if any impact to downstream property. The results of the original report indicated that detention is not required for this site . This analysis is still valid. • Addendum to Drainage Report for Christ United Methodist Church 4203 State Highway 6 South College Station, Texas September 1999 Prepared by: Joseph P.
