The legal description is Ponderosa Place, Block 21, Lot 6. The proposed improvements consist of a s, 000 square foot one story building, parking lot and the associated infrastructure. The drainage area consists of 0.88 acres of grassland and an existing building on the lot to the south. The terrain slopes with an average grade of 3.3%. The site is zoned C-2 and is being developed by Mr. Carl Rugg, Bovine Elite, Inc. 7610 Eastmark Drive, College Station, Texas (409) 693-0388. The latest Flood Insurance Rate Maps for College Station show no portion of the site contains or abuts the regulatory 100-year flood plain or floodway. The goal of this study is to provide an economic design that will effectively manage the runoff produced by a 5, 10, 25, SO and 100 year storm by the use of a detention facility that will not increase the peak rate of discharge for the watershed and a design that complies with the City of College Station Stormwater Design Standards. EXISTING DRAINAGE BASIN DESCRIPTION: The storm runoff drains overland in a northwestern direction. Approximately half of the runoff, .4~ drai.n an acce-ss e at the rear of the lot and the other portion, The detention BOVINE ELITE, INC. DRAINAGE ANALYSIS PAGE 1 OF 2 PAGES basin is designed c:..;;;;...>---runoff flowing to ~ongmire rive 0.46 acr PROPOSED DRAINAGE: The proposed design will route the flow across the site and concentrate it at the detention facility. At that point it will be discharged onto Longmire Drive. The discharge from the basin will not exceed the predevelopment conditions for any of the design storms. DRAINAGE FACILITY DESIGN: Predevelopment discharges for the 5, 10, 25, 50 and 100 year storms were determined using the Haestead Methods Quick TR-55 rational method for computing runoff hydrographs. Detailed calculations are contained in PREDEVELOPMENT CONDITIONS. Post-development discharges were determined utilizing the same hydrography methodology. The detention facility was modeled using the Hae stead Methods Pond Pack computer program. Hydrographs were determined for inflow to the detention facility and outflows from the detention facility. Detailed calculations are contained in POSTDEVELOPMENT CONDITIONS. A summary of the results of all discharge calculations is presented in Table One. The detention facility is designed to function for a range of storms up to the 100 year storm. Outflow for storms up to the 100 year storm are contained within the outlet control works and a 6" freeboard is provided to the top of berm. CONCLUSION: This project is in compliance with the City of College Station Stormwater Design Standards. BOVINE ELITE, INC.

The legal description is Ponderosa Place, Block 21, Lot 6 . The proposed improvements consist of a 5, 000 square foot one story building, parking lot and the associated infrastructure. The drainage area consists of 0.81 acres of grassland and an existing building on the lot to the south. The terrain slopes with an average grade of 3 .3%. The site is zoned C-2 and is being developed by Mr. Carl Rugg, Bovine Elite, Inc. 7610 Eastmark Drive, College Station, Texas (409) 693-0388. The latest Flood Insurance Rate Maps for College Station show no portion of the site contains or abuts the regulatory 100-year flood plain or floodway. The goal of this study is to provide an economic design that will effectively manage the runoff produced by a 5, 10, 25, 50 and 100 year storm by the use of a detention facility that will not increase the peak rate of discharge for the watershed and a design that complies with the City of College Station Stormwater Design Standards. EXISTING DRAINAGE BASIN DESCRIPTION: The storm runoff drains overland in a northwestern direction. Approximately half of the runoff drains toward an access easement at the rear of the lot and the other portion drains toward Longmire Drive. BOVINE ELITE, INC. DRAINAGE ANALYSIS PAGE 1 OF 2 PAGES PROPOSED DRAINAGE: The proposed design will route the flow across the site and concentrate it at the detention facility. At that point it will be discharged onto Longmire Drive. The discharge from the basin will not exceed the predevelopment conditions for any of the design storms. DRAINAGE FACILITY DESIGN: Predevelopment discharges for the 5, 10, 25, 50 and 100 year storms were determined using the Haestead Methods Quick TR-55 rational method for computing runoff hydrographs. Detailed calculations are contained in PREDEVELOPMENT CONDITIONS. Post-development discharges were determined utilizing the same hydrography methodology. The detention facility was modeled using the Hae stead Methods Pond Pack computer program. Hydrographs were determined for inflow to the detention facility and outflows from the detention facility. Detailed calculations are contained in POSTDEVELOPMENT CONDITIONS. A summary of the results of all discharge calculations is presented in Table One. The detention facility is designed to function for a range of storms up to the 100 year storm. Outflow for storms up to the 100 year storm are contained within the outlet control works and a 6" freeboard is provided to the top of berm. CONCLUSION: This project is in compliance with the City of College Station Stormwater Design Standards. BOVINE ELITE, INC. DRAINAGE ANALYSIS PAGE 2 OF 2 PAGES PONDEROSA DR.

Hester Engineering 7607 Eastmark Suite 250 College S~tion, Tx 77840 RE: Bovine Elite Dear Mike. Post Office Box 9960 1101 Texas Avenue College Station, Texas 77842-9960 (409) 764-3500 March 14, 1995 I have reviewed the plans and reports for Bovine Elite. The following are comments that need to be addressed: WATERLINE ANALYSIS I believe that a segment of line in this report (line #4) that you've shown as a 12" line is in reality a 6" line. If your record differ from mine, let me know and we'll figure out which record is indeed correct Please rerun with line #4 as a 6" line. DRAINAGE REPORT In the report, you state that almost 1/2 of the site drains tow d the access easement (predevelopment), however, in your calculations, you don't quantify pre and post (longrnire) and pre and post (access easement) flows. I'll need you to quantify those numbers. You also define DA #1 and DA #2 in Table One, but there.isn't' a ~phic to define these 2 drainage~ (can you please provide on an existing map in the report). · J ~ .~ PLANS All comments are noted on the plans. If you have any questions, please call . Thanks. ~-~ Veronica Morgan Asst.

The legal description is Ponderosa Place, Block 21, Lot 6. The proposed improvements consist of a 5, 000 square foot one story building, parking lot and the associated infrastructure. The drainage area consists of 0.81 acres of grassland and an existing building on the lot to the south. The terrain slopes with an average grade of 3.3%. The site is zoned C-2 and is being developed by Mr. Carl Rugg, Bovine Elite, Inc. 7610 Eastmark Drive, College Station, Texas (409) 693-0388. The latest Flood Insurance Rate Maps for College Station show no portion of the site contains or abuts the regulatory 100-year flood plain or floodway. The goal of this study is to provide an economic design that will effectively manage the runoff produced by a 5, 10, 25, 50 and 100 year storm by the use of a detention facility that will not increase the peak rate of discharge for the watershed and a design that complies with the City of College Station Stormwater Design Standards. EXISTING DRAINAGE BASIN DESCRIPTION: The storm runoff drains overland in a northwestern direction. Approximately half of the runoff drains toward an access easement at the rear of the lot and the other portion drains toward Longmire Drive. BOVINE ELITE, INC. DRAINAGE ANALYSIS PAGE I OF 2 PAGES PROPOSED DRAINAGE: The proposed design will route the flow across the site and concentrate it at the detention facility. At that point it will be discharged onto Longmire Drive. The discharge from the basin will not exceed the predevelopment conditions for any of the design storms. DRAINAGE FACILITY DESIGN: Predevelopment discharges for the 5, 10, 25, 50 and 100 year storms were determined using the Haestead Methods Quick TR-55 rational method for computing runoff hydrographs. Detailed calculations are contained in PREDEVELOPMENT CONDITIONS. Post-development discharges were determined utilizing the same hydrography methodology. The detention facility was modeled using the Haestead Methods Pond Pack computer program. Hydrographs were determined for inflow to the detention facility and outflows from the detention facility . Detailed calculations are contained in POSTDEVELOPMENT CONDITIONS . A summary of the results of all discharge calculations is presented in Table One. The detention facility is designed to function for a range of storms up to the 100 year storm. Outflow for storms up to the 100 y~ar storm are contained within the outlet control works and a 6 11 freeboard is provided to the top of berm. CONCLUSION: This project is in compliance with the City of College Station Stormwater Design Standards. BOVINE ELITE, INC. DRAINAGE ANALYSIS PAGE 2 OF 2 PAGES PONDEROSA DR .

The site has an existing fire hydrant located in the front of the lot. The proposed building will not have a sprinkler system. I have contacted the fire department (C. S. F. D) for their input and requirements and they have requested fire lanes. I have determined the fire flow requirements from the formula the C.S.F.D. provided. With a fire flow of 1450 gpm on the fire hydrant the analysis reveals that the residual pressure and velocities stay within acceptable limits. As usual this project is on a short timeline and I need to obtain the development permit as soon as possible. At your earliest convenience please review the report and contact me with any additional flow conditions or questions.

Hester Engineering 7607 Eastmark Suite 250 College Station, Tx 77840 RE: Bovine Elite Dear Mike, CITY OF COi J_EGE STATION Post Office Box 9960 1101 Texas Avenue College Station, Texas 77842-9960 (409) 764-3500 March 14 , 1995 I have reviewed the plans and reports for Bovine Elite. The following are comments that need to be addressed: WATERLINE ANALYSIS I believe that a segment of line in this report (line #4) that you've shown as a 12" line is in reality a 6" line. If your record differ from mine, let me know and we'll figure out which record is indeed correct. Please rerun with line #4 as a 6" line. DRAINAGE REPORT in the report, you state that almost 1/2 of the site drains toward the access easement (predevelopment}, however, in your calculations, you don't quantify pre and post (longmire) and pre and post (access easement) flows. I'll need you to quantify those numbers. You also define DA #1 and DA #2 in Table One, but there isn't' a graphic to define these 2 drainage areas (can you please provide on an existing map in the report}. ' PLANS All comments are noted on the plans. If you have any questions, please call . Thanks. Veronica Morgan Asst.
