TRACT DESCRIPTION The Holleman Sixplexes covers a 3.84-acre tract located at the southeast corner of the intersection of Holleman Drive and Bright Circle. A separate 24"x36" sheet, Drainage, part of the infrastructure construction plans, is part of this report. The adopted Flood Insurance Study does not identify the existence of a 100-flood plain affecting this tract (Map# 48041 C 0144 C, July 2, 1992). 2 . STORMWATER RUNOFF All of the runoff from the 3.84 acres flows in a general southeast direction, as sheet flow, onto Bright Circle. Attached to this report is my letter of January 20, 1999 to Constantin Barbu, which describes the criteria followed in this study. The only difference between the present study and the Hammonds report is that all 3 .84 acres drain onto Bright Circle and not just 3.23 acres. The current site is currently vacant. Exhibit 1 shows the tract , its location and its topography. All surveys were performed by Brad Kerr, R.P .L.S. Exhibit 2 shows the runoff calculations for 5, 1 O, 25, 50 and 100-year rainfalls. Runoff detention computations have been made using the 25-year return period. The runoff increases for 17.88 cfs to 35 .76 cfs from pre to post-development conditions . Because of the nature of the site plan and in order to mitigate the effect of the increase runoff a detention pond is proposed to be located in the driveway and parking area immediately adjacent to Bright Circle. Please see the referenced 24"x36" drawing. 3. INFLOW HYDROGRAPHS Haestad Methods Quick Tr-55 V. 5.47 has been used for the analysis given in Exhibit 3 (in 3 pages). This Exhibit graphically shows individual hydrographs for all storm frequencies. At the end of this exhibit there is a tabular Grand Summary for all storm frequencies. 4. DETENTION POND As indicated above a detention pond is proposed. This pond will be bound by a berm built along Bright Circle, 1.0' above and 2.5' behind the top of the parking lot curb. The height of the curb at the curb cut that defines the outlet structure is proposed to be 8". Pond elevation will be 303.5'. -1 - • Exhibit 4 shows the storage volume calculations based on the proposed grading of the : !<ing lot and drives . This Exhibit also shows a curb cut rating table used for the preliminary sizing of the outlet weir from the pond . Haestad Methods Pondpack V. 5.21 has been used in the ponding calculations . Exhibit 5 shows the input data for the proposed Vertical -Rectangular weir (curb cut). Exhibit 6 (10 pages) shows the routing calculations for a multiple storm . Peak outflows for each frequency do not exceed pre - development conditions . The following is the routing summary in terms of maximum outflow allowed (pre -development conditions) and peak attained : Storm Max. Allowed Peak Attained Max. Elevation 5-year 11.82 11 .70 303.13 10-year 13.26 12.79 303.21 25-year 15.15 14.22 303 .30 50-year 17 .12 15.72 303 .4~ 100-year 17.88 16.29 303.44 Exhibit 7 shows the calculations associated with the 8.3'-wide flume that drains the ponc:f bver the surface onto Bright Circle . The above referenced Grading Plan indicates the location of the pond and depicts the location and construction details of the outlet weir structure (curb cut, berm cut and lining and concrete flume).

C. Cooper Place Subdivision College Station , TX Dear Constantin: I have reviewed the 11 Stormwater Drainage Analysis11 report prepared for the 0. C . Cooper Subdivision by M. L. Hammons, P. E., in August 1996. The report was the basis for the design of the detention facilities that were built as part of the development of the duplex lots along Bright Circle. These facilities were designed for a 100-year even stormwater flow. Only pre-development stormwater input from the proposed apartment area was included in the design . Therefore the proposed site plan for the apartments will require a detention facility according to City Ordinance to accommodate post development runoff. Of the 3 .9 acres in this project approximately 3 .23 acres currently drain towards Bright circle and the remaining 0 .67 acre drains towards Holleman Drive.

TRACT DESCRIPTION ~€ ~~\__\r B ,...."S,IZ--cO i ~\~~ The Holleman Sixplexes covers a net 3.7-acre tract (after a dedicatio rf>..~~ 15'-wi ~~ additional Holleman Drive right of way) and is located at the northeast cor ~~S,~~ection of Holleman Drive and Bright Circle. GQ\-:(3.\~'f;.'f:.~ The enclosed 24"x36" sheet, Drainage Plan , which is part of the infra:fructure construction plans, is part of this report. The adopted Flood Insurance Study does not identify the existence of a 100-flood plain affecting this tract (Map # 48041 C 0144 C, July 2 , 1992). 2. STORMWATER RUNOFF All of the runoff from the 3. 70 acres flows in a general southeast direction, as sheet flow, onto Bright Circle. In August 1996, in connection with the development of Bright Circle, M. L. Hammons, P.E. reported on the drainage design for the 0. C. Cooper Place Subdivision . This report took into account the pre-development (vacant land) runoff from what is now known as the Holleman Sixplexes for the design of the stormwater detention facility that was built at the end of the cul-de- sac. The runoff from the Sixplexes was to be conveyed to said facility on the surface of Bright Circle. The Sixplexes site continues to be vacant. Exhibit 1 shows the tract, its location and its topography. The entire tract constitutes drainage Section 1 . All field surveys were performed by Brad Kerr, R.P.L.S. Exhibit 2 shows the runoff calculations for 5, 1 O, 25, 50 and 100-year rainfalls. This exhibit shows the values assumed using the Rational Method. The time of concentration used was 1 O minutes. On site detention computations have been made using the 100-year return period. The runoff increases from 17.23 cfs to 32.30 cfs (pre to post development conditions). Because of the nature of the site plan and in order to mitigate the effect of the increase runoff a detention pond is proposed to be located in the driveways and parking areas adjacent to Bright Circle. Please see the referenced 24"x36" drawing. 3. INFLOW HYDROGRAPHS Haestad Methods Quick Tr-55 V. 5.47 has been used for the analysis given in Exhibit 3 (in 3 pages). This Exhibit graphically shows individual hydrographs for all storm frequencies. At the end of this exhibit there is a tabular Grand Summary for all storm frequencies. The required storage for the 100-yr storm is calculated as 0.22 ac -ft. 4. DETENTION POND As indicated above a detention pond is proposed . This pond will be bound by the curb around the parking lot by the 302.80 contour. The highest allowable curb in the parking lot is 10 inches (0.833'). The outlet structure will be a vertical-rectangular weir consisting of a 7.4 ' net curb cut on a 8.0 ' total cut. In order to avoid possible vehicle pass through at that location a curb stub 0 .8' long will be left at the center of the curb cut. Since the curb at this location is 1 O" high the three parking spaces affected w ill be 20 ' long and will be provided with curb stops two feet in front of the high curb . therefore the net parking space length w ill be 18'. Following the weir there will be a 22.5 ' long rectangular concrete flume, 8.0 ' wide , at a 3 .7% slope, connecting with the gutter on Bright Circle. This flume will have a 4" curb on either s ide. Exhibit 4 shows the storage volume calculations based on the proposed g rad ing of the parking lot and drives. This Exhibit also shows a curb cut rating table used for the preliminary sizing of the outlet weir from the pond . Haestad Methods Pondpack V. 5.21 has been used in the ponding calculations. Exhibit 5 shows the input data for the proposed Vertical-Rectangular weir (curb cut). Exhibit 6 (10 pages) shows the routing calculations for a multiple storm . Peak outflows for each frequency do not exceed pre- development conditions. The following is the routing summary in terms of maximum outflow allowed (pre-development conditions), peak flow attained and maximum contour elevation under post development conditions: Storm Max. Allowed Peak Attained Max. Elevation 5-year 11 .39 11 .38 302 .60 10-year 12.78 12.46 302 .64 25-year 14.60 13 .86 302 .69 50-year 16.50 15.35 302.75 100-year 17.23 15.92 302.77 Exhibit 7 shows the calculations associated with the 8.0 '-wide flume that drains the pond into the Bright Circle's gutter. The estimated post development of Q-100 will rise 0 .28 ' (3.4 ") in the flume and will flow out onto Bright Circle at 7.23 fps. Currently Bright Circle handles 17.23 cfs from the Sixplexes tract. The above referenced Grading Plan indicates the location of the pond and depicts the location and ''''"'''1• ~ ction details of the outlet weir structure (curb cut, and concrete flume) . ..:."'_ .... -<\ t. o F r L' 'e• : A. ~ .... ..... ••• <: _J,.. .,. -' •' '• 'IA f'A : C, ••• ••• •• ••• -'lf' rt -'*. ·. * ~ s *... ·..

TRACT DESCRIPTION ~ o~~\; ~<?,<?, ~ ...-~i G i co \S The Holleman Sixplexes covers a net 3 .7-acre tract (after a }edicatio ~~a 15 '-~~N or additional Holleman Drive right of way) and is located at the northeast c ~~Rt-l~~ction of Holleman Drive and Bright Circle. co"\) G\~'t;,€ ~~ The enclosed 24"x36" sheet, Drainage Plan , which is part of the infrastructure construction plans, is part of this report. The adopted Flood Insurance Study does not identify the existence of a 100-flood plain affecting this tract (Map# 48041 C 0144 C, July 2 , 1992). 2. STORMWATER RUNOFF All of the runoff from the 3.70 acres flows in a general southeast direction, as sheet flow, onto Bright Circle. In August 1996, in connection with the development of Bright Circle , M. L. Hammons , P.E . reported on the drainage design for the 0 . C. Cooper Place Subdivision. This report took into account the pre-development (vacant land) runoff from what is now known as the Holleman Sixplexes for the design of the stormwater detention facility that was built at the end of the cul-de- sac. The runoff from the Sixplexes was to be conveyed to said facility on the surface of Bright Circle. The Sixplexes site continues to be vacant. Exhibit 1 shows the tract, its location and its topography. The entire tract constitutes drainage Section 1 . All field surveys were performed by Brad Kerr , R.P.L.S. Exhibit 2 shows the runoff calculations for 5, 1 O, 25, 50 and 100-year rainfalls . This exhibit shows the values assumed using the Rational Method. The time of concentration used was 1 O minutes . On site detention computations have been made using the 100-year return period. The runoff increases from 17.23 cfs to 32.30 cfs (pre to post development conditions). Because of the nature of the site plan and in order to mitigate the effect of the increase runoff a detention pond is proposed to be located in the driveways and parking areas adjacent to Bright Circle. Please see the referenced 24"x36" drawing. 3. INFLOW HYDROGRAPHS Haestad Methods Quick Tr-55 V. 5.47 has been used for the analysis given in Exhibit 3 (in 3 pages). This Exhibit graphically shows individual hydrographs for all storm frequencies. At the end of this exhibit there is a tabular Grand Summary for all storm frequencies . The required storage for the 100-yr storm is calculated as 0.22 ac-ft . c---- .. ' 4. DETENTION POND As indicated above a detention pond is proposed . Th is pond will be bound by the curb around the parking lot by the 302.80 contour. The highest allowable curb in the parking lot is 1 o inches (0.833'). The outlet structure will be a vertical-rectangular weir consisting of a 7.4' net curb cut on a 8.0' total cut. In order to avoid possible vehicle pass through at that location a curb stub 0.8 ' long will be left at the center of the curb cut. Since the curb at this location is 1 O" high the three parking spaces affected will be 20 ' long and will be provided with curb stops two feet in front of the high curb . therefore the net park ing space length will be 18'. Following the weir there will be a 22 .5' long rectangular concrete flume , 8.0 ' wide, at a 3 .7% slope, connecting with the gutter on Bright Circle . This flume will have a 4" curb on either side. Exhibit 4 shows the storage volume calculations based on the proposed grading of the parking lot and drives . This Exhibit also shows a curb cut rating table used for the prel iminary sizing of the outlet weir from the pond. Haestad Methods Pondpack V. 5.21 has been used in the ponding calculat ions. Exhibit 5 shows the input data for the proposed Vertical -Rectangular we ir (curb cut). Exhibit 6 (1 o pages) shows the routing calculations for a multiple storm . Peak outflows for each frequency do not exceed pre- development conditions. The following is the routing summary in terms of maximum outflow allowed (pre -development conditions), peak flow attained and maximum contour elevation under post development cond itions : Storm Max. Allowed Peak Atta ined Max . Elevation 5-year 11.39 11 .38 302.60 10-year 12 .78 12.46 302 .64 25 -year 14.60 13 .86 302.69 50-year 16.50 15.35 302.75 100-year 17.23 15 .92 302 .77 Exhibit 7 shows the calculations associated with the 8.0 '-wide flume that drains the pond into the Bright Circle's gutter . The estimated post development of Q-100 will rise 0.28 ' (3.4 ") in the flume and will flow out onto Bright Circle at 7.23 fps . Currently Bright Circle handles 17.23 cfs from the Sixplexes tract. ~,,,~«:\~~le referenced Grading Plan indicates the location of the pond and depicts the location and ~---'"';, £.
