The supplemental information that is presented in this report can be divided into two (2) separate categories . . The initial information presented is the design parameters for the fifteen (15) subbasins associated with the analysis. Secondly, the limits of the 100 year flood elevation for Phase Ill of the Southwest Crossing at Bee Creek project have been sufficiently defined such that it can be delineated on this tract. The reason Gessner EngineerjQg delineated the 100 year flood plain is for the purpose of determining if the right-of-way outside of the 100 ear fl · · need to be dedicated ad·acent to Creek u ary B to meet t enwa and Bikeway Plan . The location of the 1.Q O year flood elev§l!iQ.o_ as delineated by this analysis 1s 1sc osed in E.xhibit A as Figure 1. The area in which the 100 year flood plain was defined is the initial tract of land located directly north of the junction of Bee Creek Tributary B and Southwest Parkway. This site is currently noted as Southwest Crossing at Bee Creek Developmen t, Phases I , II , Ill and IV. Phase Ill of the development is the most easterly section of the tract and is currently undeveloped . Bee Creek Tributary B forms the easterly boundary of Phase Ill. Since the proposed development abuts the Primary System for Bee Creek Tributary B , the proposed development Southwest Crossing at Bee Creek was allowed to be constructed without detention based upon the results of the original study. This analysis indicated that if no detention is provided for this development, the flood elevation rises 0.02 feet. Therefore Gessner Engineering reguested on behalf of the client , that development gf this tract without detention he considered. The City of College Station allowed the development to be constructed without detention. The drainage basin associated with the original drainage analysis consists of approximately 272 acres divided into fifteen (15) subbasins . The subbasins consist of residential (single and multifamily), commercial, parkland and undeveloped tracts . The slope for each subbasin ranges from two (2) percent or less . The volume of runoff was calculated by using the Soil Conservation Service design storm distribution for each subbasin. The channel (reach) routing was performed by the Modified Puls Method. Gessner Engineering -------- Introduction This original drainage study was performed to determine the elevation of the 100 year storm flood on the Southwest Crossing at Bee Creek tract from the North Fork of Tributary "B" of Bee Creek located in College Station, Texas. The Federal Emergency Management Administration (FEMA) has previously completed a study of this portion of Bee Creek. The results of that analysis are reported upon the individual FEMA panel sheets. The City of College Station Greenway and Bikeway Plan indicates that this portion of Bee Creek is desirable for the continuation of the proposed bikeway. Discussions with the City of College Station staff indicated that additional information needs to be presented to determine the extent that the Greenway and Bikeway Plan will encumber Phase Ill of the Southwest Crossing at Bee Creek project. The required items are as follows: 1) Submit the design parameters used in the hydrologic analysis for each of the fifteen (15) individual subbasins . 2) Supply cross sections used along Bee Creek for Phase Ill. 3) Delineate the 100 year flood plain on a plan view of the Phase Ill tract. 4) Jf the 100 year flood is contained wjth in the high banks of the channel, a twenty (20) foot easement will need ta he seelieated f6r tFis [Jroposed hike and _p ike tral). Drainage Area Description A total of fifteen (15) subbasins were identified with regards to this hydrologic and hydraulic analysis of the North Fork of Tributary "B" of Bee Creek upstream from Southwest Parkway in Colleg'e Station. The location of the fifteen (15) subbasins is denoted on Figure 2. The fifteen (15) subbasins are approximately bounded by the South Gate Area along George Bush Drive to the north, Marion Pugh Drive to the west , Welsh Avenue to the east and Southwest Parkway to the south. The area and runoff characteristics for each subbasin were determined using the Soil Conservation Service (SCS) methodology to describe drainage basins. These engineering parameters are provided in Table 1.

The SCS Method unit hydrograph ,..-was utilized with a Type II, twenty-four (24) hour SCS storm distribution in this analysis. The channel (reach) routing was performed by the Modified Puls Method. The analysis resulted in a peak flow of approximately 780 cfs for the 100 year storm interval at Southwest Parkway. Gessner Engineering divided the subject tract into seven (7) separate reaches to simulate the flow in Bee Creek across the tract. The intersection of the North Fork of Tributary "B" of Bee Creek and Southwest Parkway is depicted as Junction 80 in the model. The estimated flood elevation for the 100 year event is approximately 291.6 feet. PondPack® is a stormwater modeling program for urban hydrology and detention pond design . Its major function is to analyze a simple site or complex, networked watershed for pre-and post-developed conditions. It is also used to estimate storage requirements ; compute outlet rating curves with tail water impacts; and analyze interconnected ponds with multiple outfalls and bi-directional flow . PondPack® has been accepted by the U.S. Federal Emergency Management Agency (FEMA) and added to its list of numerical models accepted for use in the National Flood Insurance Program (NFIP). Gessner Engineering -------- The seven (7) cross sections of Bee Creek used to determine the 100 year flood plain elevat ion on Phase Ill of The Southwest Crossing at Bee Creek project are labeled on Figure 3. The actual physical input for the PondPack® software cross sections are presented in Exhibit B. The information provided in Exhibit B is the 100 year flow for each reach and the elevation of the 100 year flow for each cross section . Gessner Engineering -------- Concl us ions The hydrologic and hydraulic analysis of the North Fork of Trib utary "B" of Bee Creek indicates that the 100 year flood plain elevation (291.6) at the upstream intersection of Southwest Parkway is equivalent to that indicated by the FEMA Flood Insurance Rate Map Panel 48041C0182 C for Brazos County, Texas. The estimated limit of the 100 year flood is depicted in Figure 1. The estimated elevation of the 100 year flood plain at each section is provided in Table 2.

Executive Summary This engineering report presents the findings of the engineering drainage analysis with respect to Bee Creek Tributary B located in College Station, Texas. Based on the . results of our investigation, Gessner Engineering, LLP ·believes that the limits of the 100 year flood elevation have been defined. The location of the 100 year flood elevation as delineated by this analysis is disclosed in Exhibit A as Figure 1. A review of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map Panel 48041C0182 C for Brazos County, Texas and Incorporated Areas effective July 2, 1992 (see Exhibit A) reveals that the 100 year flood plain is essentially equivalent to the boundary determined by this analysis. The primary area analyzed is located north of the junction of Bee Creek Tributary B and Southwest Parkway. The subject drainage basin consists ·of approximately 272 · acres divided into fifteen (1 .5) subbasins~ The subbasins consist of. residential (single and multifamily), commercial, parkland and undeveloped tracts. The slope for each subbasin ranges from two (2) percent or less. The volume of runoff was calculated by using the Soil Conservation Service design storm distribution for each subbasin. The ··channel (reach) routing was performed by tbe Modified Puls Method. Since the proposed development abuts the Primary System for Bee Creek Tributary B, the proposed development Southwest Crossing at Bee Creek was analyzed with and without . detention to determine the affect upon the flood elevation. This analysis indicated that if no detention is provided for this development, the flood elevation rises 0.02 feet. Therefore Gessner Engineering is requesting that development of this tract without detention be considered and allnwe_d. ' Introduction . This t:1r~inage study was perfQtmed : to determine ·.the. elevation of the 1 ao year stonn .·;fl~der the North Fork t>fTnbutary ·"B" of ·see Creek located · in College Station, · :"~. . The Federal Emergency ·Management Administration (FEMA) has previously ooiriPleted a study of this portion of Bee Creek. The results· of that analysis is reported . upon the individual FEMA panel sheets. A second drainage report was completed on February 6, 2004 by Joe Orr, Inc. and sealed by Mr. David Mayo, P,.E. The results of this study indicated that the 100 year flood plain elevation was several feet higher than reported by the FEMA report. Gessner Engineering was hired by Mr. Hunter Goodwin to determine which analysis was correct so that the 100 year flood plain elevation could be established with confidence prior to commencement of development of the Southwest Crossing at Bee Creek project. -------Gessner Engineering ------- e. C. c ' ' • Drainage Area Description A total of fifteen (15) subbasins were identified with regards to this hydrologic and hydraulic analysis of the North Fork of Tributary "B" of Bee Creek upstream from So_uthwest Parkway in College Station. The location of the fifteen (15) subbasins is denoted on Figure 1. The fifteen ( 15) subbasins are approximately bounded by the South Gate Area along George Bush Drive to the north, Marion Pugh Drive to the west, Welsh Avenue to the east and Southwest Parkway to the south. The area, slope and runoff characteristics for each subbasin were determined using the Soll Conservation Service (SCS) methodology to describe drainage basins. Hydrologlc Model The PondPack® for Windows (v. 9) software developed by Haested Methods was used to model and analyze the fifteen (15) drainage subbasins and the individual channel reaches. The SCS Method unit hydrograph was utilized with a Type II, twenty-four (24) hour SCS storm distribution in this analysis. The channel (reach) routing was performed by the Modified Puls Method. The analysis resulted in a peak flow of approximately 780 cfs for the 100 year storm interval at Southwest Parkway. Gessner Engineering divided the subject tract into seven (7) separate reachs to simulate the flow in Bee Creek across the tract. The intersection of the North Fork of Tributary "B" of Bee Creek and Southwest Parkway is depicted as Junction 80 In the . / model. The estimated flood elevation for the 100 year event is approximately 292.2 fL_ feet. PondPack«> is a stormwater modeling program for urban hydrology and detention pond design. Its major function is to analyze a simple site or complex, networked watershed for pre-and post-developed conditions. It Is also used to estimate storage requirements; compute outlet rating curves with tail water impacts; and analyze loteieor:tn.eeted ponds with multiple outfalls and bi-directional flow. PondPack® has · been a:ecepted by the U.S. Federal Emergency Management Agency (FEMA) and added to its list of numerical models accepted for use In the National Flood Insurance · Program (NFIP). Coneluslons The hydrologic and hydraulic analysis of the North Fork of Tributary "B" of Bee Creek Indicates that the 100 year flood plain elevation <t913l is equivalent to that Indicated by the FEMA Flood Insurance Rate Map Pane ~'1 C0182 C for Brazos County, -------Ge;ssner Engineering ------- Texas. In addition, an analysis of the drainage system indicates that if no detention is provided for this site located along the Primary Drainage System, the elevation for the 100 flood is within 0.01 feet in either case. Gessner Engineering recommends that detention for this site be excluded in accordance with the provisions of the Stormwater Management Plan for the City of College Station Drainage Policy and Design Standards. The elimination of detention at this site will ultimately allow the discharge peak to pass through the drainage system prior to the passing of the peak discharge. In essence this condition will improve the drainage characteristics of Bee Creek. -------Gessner E11giaeeri,ng ------- Exhibit A Drainage ·Area Maps -------·&esseer Eqiaeer.ing _....;._ ____ _ I • • 1.

Based on the results of our investigation, Gessner Engineering, LLP believes that the limits of the 100 year flood elevation have been defined. The location of the 100 year flood elevation as delineated by this analysis is disclosed in Exhibit A as Figure 1. A review of the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map Panel 48041C0182 C for Brazos County, Texas and Incorporated Areas effective July 2, 1992 (see Exhibit A) reveals that the 100 year flood plain is essentially equivalent to the boundary determined by this analysis. The primary area analyzed is located north of the junction of Bee Creek Tributary B and Southwest Parkway. The subject drainage basin consists of approximately 272 acres divided into fifteen (15) subbasins. The subbasins consist of residential (single and multifamily), commercial, parkland and undeveloped tracts. The slope for each subbasin ranges from two (2) percent or less. The volume of runoff was calculated by using the Soil Conservation Service design storm distribution for each subbasin. The channel (reach) routing was performed by the Modified Puls Method. Since the proposed development abuts the Primary System for Bee Creek Tributary B, the proposed development Southwest Crossing at Bee Creek was analyzed with and without detention to determine the affect upon the flood elevation. This analysis indicated that if no detention is provided for this development, the flood elevation rises 0.02 feet. Therefore Gessner Engineering is requesting that development of this tract without detention be considered and allowed. Introduction This drainage study was performed to determine the elevation of the 100 year storm flood for the North Fork of Tributary "B" of Bee Creek located in College Station, Texas . The Federal Emergency Management Administration (FEMA) has previously completed a study of this portion of Bee Creek. The results of that analysis is reported upon the individual FEMA panel sheets. A second drainage report was completed on February 6, 2004 by Joe Orr, Inc. and sealed by Mr. David Mayo, P,.E. The results of this study indicated that the 100 year flood plain elevation was several feet higher than reported by the FEMA report. Gessner Engineering was hired by Mr. Hunter Goodwin to determine which analysis was correct so that the 100 year flood plain elevation could be established with confidence prior to commencement of development of the Southwest Crossing at Bee Creek project. Drainage Area Description A total of fifteen (15) subbasins were identified with regards to this hydrologic and hydraulic analysis of the North Fork of Tributary "B" of Bee Creek upstream from Southwest Parkway in College Station. The location of the fifteen (15) subbasins is denoted on Figure 1. The fifteen (15) subbasins are approximately bounded by the South Gate Area along George Bush Drive to the north, Marion Pugh Drive to the west , Welsh Avenue to the east and Southwest Parkway to the south . The area, slope and runoff characteristics for each subbasin were determined using the Soil Conservation Service (SCS) methodology to describe drainage basins. Hydrologic Model The PondPack® for Windows (v. 9) software developed by Haested Methods was used to model and analyze the fifteen (15) drainage subbasins and the individual channel reaches. The SCS Method unit hydrograph was utilized with a Type 11, twenty-four (24) hour SCS storm distribution in this analys is. The channel (reach) routing was performed by the Modified Puls Method. The analysis resulted in a peak flow of approximately 780 cfs for the 100 year storm interval at Southwest Parkway. Gessner Engineering divided the subject tract into seven (7) separate reachs to simulate the flow in Bee Creek across the tract. The intersection of the North Fork of Tributary "B" of Bee Creek and Southwest Parkway is depicted as Junction 80 in the model. The estimated flood elevation for the 100 year event is approximately 292 .2 feet. PondPack® is a stormwater modeling program for urban hydrology and detention pond design . Its major function is to analyze a simple site or complex, networked watershed for pre-and post-developed conditions. It is also used to estimate storage requirements; compute outlet rating curves with tail water impacts ; and analyze interconnected ponds with multiple outfalls and bi-directional flow. PondPack® has been accepted by the U.S. Federal Emergency Management Agency (FEMA) and added to its list of numerical models accepted for use in the National Flood Insurance Program (NFIP). Conclusions z_qz_~ c~ ~D\Je.-J The hydrologic and hydraulic analysis of the North Fork of Tributary "B" of Bee Creek indicates that the 100 year flood plain elevation (~Q1 .3-) is equivalent to that indicated by the FEMA Flood Insurance Rate Map Panel 48041 C0182 C for Brazos County , Texas. In addition, an analysis of the drainage system indicates that if no detention is provided for this site located along the Primary Drainage System, the elevation for the 100 flood is within 0.01 feet in either case . The associated flow in Bee Creek shall does not change if the flow from the site is detained or not (See Exhibit C). Gessner Engineering recommends that detention for this site be excluded in accordance with the provisions of the Stormwater Management Plan for the City of College Station Drainage Policy and Design Standards . The elimination of detention at this site will ultimately allow the discharge peak to pass through the drainage system prior to the passing of the peak discharge. In essence this condition will improve the drainage characteristics of Bee Creek. Subarea f'O ~ ~~ ,,,.;;·.o Add/ink 10 ~ Subarea ·.-;,.::·!

The parameters used for design and the existing conditions of the on-site area are incorporated to show how the final domestic water design will meet the requirements of the Uniform Design Manual -Domestic Water. The analysis was performed using WaterCAD as developed by Haested Methods. General Location and Description: The proposed development is located at the northeast corner of the intersection of Southwest Parkway and Wellborn Road (FM 2154 ). The proposed project site contains one (1) commercial lot platted as Lot 1, William Brooke Hunter Estates Subdivision, and is zoned C-1 General Commercial. The approximately 3.00 acre site to be developed in Phase I is undeveloped grassland. The average slope for the site is approximately one (1) percent in a southeasterly direction. The current land cover is considered natural grassland, and the proposed developed site will contain both landscaped areas and impervious areas. The proposed site is owned by Andy Restivo with Restivo Investments. The mailing address for Restivo Investments is P.O . Box 5429, Waco, Texas 76708. The Project Manager and primary contact for this project is Mr. Hunter Goodwin. Mr. Goodwin 's address is 311 Chimney Hill Drive, College Water Report Southwest Crossing at Bee Creek -Phase I Lot 1, William Brooke Hunter Estates Subdivision Station , Texas 77840. Domestic Water System Description: The tract for the proposed development is served domestic water by the City of College Station via an eight (8) inch water line which extends in a northerly direction into the tract. The eight (8) inch water line branches from the twelve (12) inch domestic water line wh ich abuts the tract along the Southwest Parkway side of the property. The eight (8) inch water line extends into the tract via a public utility easement which extends to the north from Southwest Parkway . The eight (8) inch water line terminates at a fire hydrant situated on Lot 5R, Block 1 of the Schick Addition, Phase 2. This Lot 5R, Block 1 of the Schick Addition is located directly north of the subject tract to be developed. A second fire hydrant currently is situated at the south end of the subject tract next to the convenience store access off of Southwest Parkway. The proposed Southwest Crossings at Bee Creek development shall be served by the eight (8) inch waterline. Each individual building shall be individually served by a service tap and will be individually metered . The developer intends to extend the existing system by looping a line which provides for the peak demand usage at the facility , fire sprinkler system flow and fire hydrants to serve the structure in case of fire . The 2000 International Plumbing Code was used to determine the peak demand for the facility by the Fixture Count method . A total of 750 fixture units are estimated for the ultimate development of both Phase I and Phase 11 of the Southwest Crossing at Bee Creek domestic water usage . This is equivalent to a peak water demand of approximately 170 Water Report Southwest Crossing at Bee Creek -Phase I Lot 1, William Brooke Hunter Estates Subdivision gallons per minute (gpm) based upon Table II of the Bryan/College Station Uniform Design Guidelines for Domestic Water. Gessner Engineering used a 200 gpm peak water demand for the system analysis. Gessner Engineering used the parameters outlined in Appendix B of the 2000 International Fire Code to determine the number of fire hydrants necessary for the site. The proposed Phase I structures enclose 21,000 square feet (s.f.) in three (3) buildings. However, ultimate development in the area could result in approximately 28,000 s.f. of development. The type of construction as per the 2000 International Building Code is Type llB. Table B105.1 of the 2000 International Fire Code indicates that a building (Type llB construction) with 28,000 s.f. of fire area has a minimum required fire flow of 3,500 gpm for a three (3) hour duration. However, the largest Fire Area is 9,000 square feet as per the IPC 2000 definition. Therefore the minimum required fire flow can be reduced to 2,000 9Q!!l due to the size of the Fire Area . A review of Table C105.1 of the 2000 International Fire Code indicates that the minimum number of fire hydrants required for the site is two (2). The average spacing between the hydrants shall be no more than 500 feet. The maximum distance from any point on the street (fire lane) to a hydrant is 250 feet. Based upon these guidelines, the two (2) fire hydrants present exceed the requirements for this site. The system was designed to provide a minimum of 2000 gpm to each hydrant concurrently in the event of a fire. In addition, Gessner Engineering provided a 200 gpm demand for the automatic sprinkler system to occur concurrently with the two (2) fire hydrants demand. Water Report Southwest Crossing at Bee Creek -Phase I Lot 1, William Brooke Hunter Estates Subdivision Domestic Water System Design Criteria: All design associated with the domestic water system improvements and with the proposed Southwest Crossing at Bee Creek is in accordance with the Uniform Design Guidelines for Domestic Water. The domestic water system design is based upon the required demands for normal operation and in the case of fire. Gessner Engineering analyzed a six (6) inch looped line from the existing eight (8) inch water line that extends to the twelve (12) inch water line located in Wellborn Road. The proposed loop line through the facility shall be polyvinyl chloride pipe (PVC). The PVC pipe shall be pressure class 200 DR14 (meeting AWWA C909 standards) forthe six (6) inch extention. Flanged ductile iron fittings shall be used as necessary. All flanged ductile iron fittings shall be wrapped with eight-mil polywrap and sealed on the edges with an approved tape . The water distribution system proposed for the Southwest Crossing at Bee Creek was sized using WaterCAD software developed by Haested Methods. The design flow calculations are based upon the following criteria: 1) normal flow of 200 gpm and 2) two (2) fire hydrants with a design flow of 2000 gpm each. The line sizes were chosen for this analysis such that the residual pressure is no less than 20 pounds per square inch (psi) and maximum velocities of not more than twelve (12) feet per second (fps) during the fire flow in both the existing and proposed mains. The exception to this guideline was the service line to the fire hydrant. The service line to the hydrant was allowed to have a velocity in excess of twelve (12) feet per second. Water Report Southwest Crossing at Bee Creek -Phase I Lot 1, William Brooke Hunter Estates Subdivision Domestic Water System Design: The WaterCAD model of the domestic water system is depicted on Figure 1. The attributes of the model are depicted in Tables 1and2 for the proposed conditions and the needed fire and consumption demands. The City of College Station provided a static pressure test at fire hydrants K-080 and K-082 located at 101 Southwest Parkway. The results of that test are attached for your review. The test results indicate that the flow hydrant (K-080) has an estimated flow rate of 1500 gpm with a residual pressure of 96 psi at static hydrant K-082. These values were used to simulate the existing pressure conditions in the model. The WaterCAD model simulated the proposed demand conditions that could occur at the Southwest Crossing at Bee Creek. The model indicates that the proposed water system improvements will supply adequate water to the facility even during the high demand situations without significant pressure loss at the site.

Gessner Engineering was selected by the Owner's Representative Hunter Goodwin, to provide the on site civil engineering services necessary to permit the site for construction. The parameters used for design and the existing conditions of the on-site area are incorporated to show how the final drainage design will accomplish the desired drainage objectives per the City of College Station Drainage Policy and Design Standards (DPDS). The proposed project tract is located adjacent to the North Fork of Tributary B of Bee Creek. The proposed site is situated at the upper end of the Creek that is considered the Primary Drainage System. As such, storm water retention is not provided as allowed by the DPDS. However, storm water design considerations were used to transport the anticipated runoff from the proposed project site . General Location and Description: The proposed development is located at the northeasterly corner of the intersection of Southwest Parkway and Wellborn Road (FM 2154) in College Station . The proposed project site consists of two (2) commercial lots zoned C-1 General Commercial. The current land cover is considered natural grassland , and the proposed site will Final Drainage Report Southwest Crossing at Bee Creek contain both landscaped areas and impervious areas . The proposed site is owned by Mr. Andy Restivo. The contact for this project is Mr. Hunter Goodwin. The mailing address for Mr. Restivo is P.O . Box 5429, Waco, Texas 76708 . The proposed tract to be developed is situated at the junction of the Primary and Secondary Drainage System Designation for the east branch of the North Fork of Tributary "B" of Bee Creek. Bee Creek generally flows in an easterly direction parallel to FM 2818 to Earl Rudder Freeway (Texas Highway 6). Bee Creek then proceeds in a southeasterly direction to its confluence with Carter Creek. A single family residential subdivision is situated to the north of the proposed development. Bee Creek forms the easterly boundary of the tract. The Parkway Circle Apartments are located east of Bee Creek. The property located south of Southwest Parkway is undeveloped. The Crossing Place Apartments are southeast of the proposed tract for development and south of Southwest Parkway. Wellborn Road and the Union Pacific Railroad tracks are situated to the west of the proposed development. A Zip 'N conven ience store is located at the northeast corner of the intersection of Southwest Parkway and Wellborn Road . The proposed development consists of approximately 9.437 acres of land . The proposed plat of the property is has divided the tract into two (2) separate lots. . The site is currently undeveloped grassland and has an average slope of one (1) to two (2) percent. The proposed development shall consist of a retail center. Phase I of the retail center shall consist of two (2) buildings and the assoc iated parking and infrastructure. An internal storm sewer system shall be constructed to remove runoff from the developed site to Bee Final Drainage Report Southwest Crossing at Bee Creek 2 Creek . Drainage Basin and Sub-Basins Description: The proposed site to be developed drains into the east branch of the North Fork of Tributary "B" of Bee Creek. The proposed site is situated at the junction of where the designation for the secondary drainage system and the primary drainage system is denoted on Figure 11-1 (Carter Creek Drainage Basin) of the DPDS for the Stormwater Management Plan for the City of College Station. The current site drains from the northwest corner to the southeast corner of the tract. Stormwater flows on the surface across the grassed field until it approaches the North Fork of Tributary B of Bee Creek. The developed site will drain into a subsurface storm sewer system which will discharge into Bee Creek at Southwest Parkway. Since the storm sewer will discharge directly into the Primary Drainage System, no detention shall be provided for this site. The logic for not providing detention for this site is that the peak flow will enter the channel prior to the upstream sub-basin peak reaches the same point in the channel. In essence, the runoff from the Southwest Crossing at Bee Creek tract would have already passed into the primary drainage system thus having a net effect of lowering the peak discharge in the basin. Gessner Engineering prepared a drainage report for the sub-basin upstream of Southwest Parkway. The results of that analysis is provided in Drainage Report for bee Creek Tributary B Up Stream from Southwest Parkway. The conclusion of th is report is that the direct discharge of runoff to the channel from this project without retention w ill have Final Drainage Report Southwest Crossing at Bee Creek 3 a negligible affect upon the 100 year flood plain elevation. The analysis indicated that the 100 year flood plain elevation is only changed 0 .02 of a foot if no retention is provided at this site . Gessner Engineering has calculated the runoff for the proposed site based upon a 100 year ultimate rainfall event. If detention was provided it would be designed only for a 25 year ultimate rainfall event being detained . Based upon the criteria of the (DPDS), the elevation of the lowest habitable floor of a structure adjacent to the watercourse of the primary drainage system shall be at least one (1) foot above the base flood elevation. The runoff discharged on site storm sewer system flows into the North Fork of Bee Creek Tributary B at the junction with Southwest Parkway. Only those portions of the proposed site adjacent to the North Fork of Bee Creek Tributary B is within the 100 year flood plain per the Federal Emergency Management Agency Flood Insurance Rate Map Panel 48041C0182 C . for Brazos County , Texas and Incorporated Areas effective July 2 , 1992 (see Exhibit "A ") and the drainage report prepared by Gessner Engineering for the sub-basin . The location of the 100 year flood plain is depicted on Figure 1. Drainage Design Criteria: The drainage analysis for the Southwest Crossings at Bee Creek was performed using the rational method to estimate the discharge from the proposed development. The rationa l method of analysis is appropriate for drainage areas up to approximately 200 acres . The basis for the rational method determination is that the maximum rate of runoff from a given drainage area for an assumed rainfall intensity occurs when all parts of the Final Drainage Report Southwest Crossing at Bee Creek 4 area are contributing to the flow at the point of discharge. This assumption is only accurate for smaller drainage areas where the rainfall is likely to occur over the entire area to be studied . Therefore this is actually a conservative approach to estimate the discharge form a specific tract of land. The rational method is also particularly applicable to urban areas where the influence of subareas of varying hydrologic characteristics may be weighted . The Rational Method is expressed by the formula Q = CIA, where : Q = Discharge in cubic feet per second (cfs) C =Runoff Coefficient (dimensionless value) I =Rainfall Intensity in inches per hour (in/hr) A = Drainage area in acres. The runoff coefficient (C) is selected by the design professional and varies with the topography of the site , land use and the moisture content of the soil at the time the rainfall event occurs . This coefficient simulates the field conditions at the subject drainage area to be analyzed . This value can change significantly between the undeveloped and developed condition of the site. A weighted value of the coefficient can be obtained to express conditions where paved and unpaved portions of the site are present. Table 5 of the Texas Department of Transportation , Bridge Division, Hydraulic Manual should be consulted for suggested values of C for various categories of ground cover. The rainfall intensity (I) is determined by the formula , I = b/(tc + d)e, where the coefficients b , d and e are constants listed by Texas counties in Table 6 of the Texas Department of Transportation , Bridge Div is ion , Hydraulic Manual. The variable , t c, is the Final Drainage Report Southwest Crossing at Bee Creek 5 - time of concentration in minutes required for the runoff to flow from the most hydraulically remote point in the watershed to the discharge point of the facility. Typically for design purposes values of tc less than 10 minutes are not cons idered . All drainage design was performed in accordance with the City DSPS . The design rainfall events analyzed for this project are the twenty-fiv e (25) year and the one hundred (100) storm event intervals. The runoff coefficients used for design purposes are summarized as follows: (a) streets (paved areas) C = 0 .85 ; (b) unimproved areas (black soil 0-3%) C = 0.20; (c) lawns (heavy soils, flat <2%) C= 0 .15; and, (d) roofs C = 0.90. The rainfall intensity was determined by the coefficients for B razos County denoted in Table A. TABLE A TxDOT Coefficients for Brazos Co unty, Texas Coeffi cients Rainfall Intensity (I) e d b 25 0.754 8 9 8.5 100 0 .730 9 6 8.0 The route selected as the most hydraulically rem ote for the site is from Wellborn Road to the intersection of Bee Creek and Southwest Pa rkway . The total travel length for runoff from the most remote location on the site in its und eveloped state is 695 linear feet. Final Drainage Report Southwest Crossing at Bee Creek 6 Drainage Facility Design: The on site drainage will consist of underground twenty-four (24) inch concrete reinforced pipe. The storm sewer system transports the runoff from the northwest portion of the project to the southeast entrance to the site. The storm sewer then extends in an easterly direction to Bee Creek. The storm sewer discharges via a concrete headwall into the existing channel of Bee Creek near Southwest Parkway. The storm sewer system has the capacity to transport up to a twenty-five (25) year storm occurrence. Conclusion: The drainage design for this site exceeds the requirements as stated in the City of College Station Drainage Policy and Design Standards. Final Drainage Report Southwest Crossing at Bee Creek 7 Exhibit A Drainage Area Map Exhibit B Drainage Area Calculations Exhibit A Drainage Area Maps Exhibit B Drainage Area Calculations Pre-Developed Conditions The drainage associated with the proposed development consists of the convenience store located at the corner of Southwest Parkway and Wellborn Road and the proposed project. The rainfall intensity for each parcel is determined as follows : I= b/(tc=d t as per the Texas Department of Transportation Hydraulic Manual where for a twenty-five (25) year storm in Brazos County b=89 , d=8 .5 and e= 0. 754 . The time of concentration varies depending on the area to be analyzed . Gessner Engineering used a tc of 21.67 minutes for the proposed site . Therefore the 125 =6 .82 inches . The pre-developed runoff associated with the proposed development is determined by the following formula: 0 25 = CIA= (0 .30)(6 .82 inches)(10 .273 acres)= 21 .02 cfs The runoff associated with the convenience store is determined by the following formula: 0 25 = CIA= (0.80)(6.82 inches)(0 .79 acres)= 4 .31 cfs The total p re-developed runoff will be 25.33 cfs. Post-Developed Conditions The post -developed runoff associated with the proposed development is de termined by the following formula : 0 25 =CIA= (0 .75)(6 .82 inches)(11 .063 acres)= 56 .59 cfs 05/08/2005 14:31 9798457858 W.M.KLUNK ERT, INC.
