The legal description is Bridle Gate Estates Phase 2 and is approximately 8.13 acres. The proposed improvements include pavement, drainage and utility improvements for 27 single family residential. The tract consists of grassland with numerous trees. The site is presently zoned R-6 and single family residential home sites will be developed. The land is being developed by Alton Ofcz.arzak, Genereal Manager, Oakwood Custom Home Group, Ltd. 4060 Texas Avenue South, College Station, Texas 979-690-1504 The proposed system will connect to an existing 8" line along Bridle Gate Drive. Static pressure information was obtained form the College Station Water and Sewer Department and was based on an onsite pressure test of the fire hydrant located along Bridle Gat e Drive. The existing static pressure is of the fire hydrant was 98 PSI , (Fire Hydrant No. Q139). The proposed subdivision was modeled using the Haestead Methods "WaterCad" program and scenarios were prepared placing fire flow demands at each proposed junction. The maximum daily demand generated by the dwelling units was added to the fire flow demand. The results of the analysis has been included in this report. ANALYSIS REQUIREMENTS I CONSTRAINTS -PVC water line pipe with a roughness coefficient of 150 -Fire flows of 1500 gpm -6" minimum waterline size -Maxim um water lin e ve lo cities during a fir e fl ow simulation were held at 10 feet per second. -Minimum residual pressures at 20 p.s.i. BRIDLE GAT E EST A TES PHAS E 2 -WATER DI STRIBlITION SYST EM ANALYS IS PAG E l OF 2 PAG ES MAXIMUM DAILY FLOW CALCULATIONS RESIDENTIAL (1 D.U.)*(2.7 PEOPLE/D.U.)*(100 GPCD)*(l DAY/1440 MIN.)(1.5)(3.0)= 0.84 GPM Maximum daily flow for a section of waterline= 0.84 gpm times the number oflots. CONCLUSION: In conclusion the proposed system can provide a fireflow demand of 1500 gpm at each fire hydrant with a residual pressure greater than 20 psi.

THE LEGAL DESCRIPTION IS BRIDLE GATE ESTATES AND IS APPROXIMATELY 21.I ACRES . THE PROPOSED IMPROVEMENTS INCLUDE PAVEMENT, DRAINAGE AND UTILITY IMPROVEMENTS FOR 53 SINGLE FAMILY RESIDENTIAL HOMES AND A 1.4 ACRE COMMERCIAL RETAIL SITE . THE TRACT CONSISTS OF GRASSLAND WITH NUMEROUS TREES . THE TERRAIN SLOPES TOWARD THE LICK CREEK DRAINAGE BASIN AT AN AVERAGE SLOPE OF LESS THAN ONE PERCENT . ACCORDING TO THE FEDERAL EMERGENCY MANAGEMENT AGENCY (FEMA) FLOOD INSURANCE RATE MAPS (48041CO 205C) THIS AREA IS OUTSIDE OF A DETAILED STUDY. THE SITE IS ZONED R-6 FOR THE SINGLE FAMILY RESIDENTIAL AREA AND C-1 FOR THE SMALL COMMERCIAL AREA AND IS BEING DEVELOPED BY MR . ALTON OFCZARZAK, OAKWOOD CUSTOM HOMES, 1911 TEXAS AVENUE SOUTH , COLLEGE STATION , TEXAS 409 .696. 7206. EXISTING DRAINAGE BASIN DESCRIPTION : THE DRAINAGE AREA FOR THE SITE BEGINS WITH A HIGH POINT ALONG THE WEST SIDE OF THE PROPOSED DEVELOPMENT . FROM THIS POINT STORM WATER FLOWS IN AN EASTERLY DIRECTION AND IN THE MIDDLE OF THE SITE SPLITS WITH A PORTION OF THE RUNOFF GOING NORTH TOWARD THE NORTH FORK OF LICK CREEK BASIN REFERENCE No. 8, REGULATORY CHANNEL REACH NO . Ill AND A PORTION GOING SOUTH TOWARD THE LICK CREEK REGULATORY CHANNEL REACH No . IV, SEE GRAPHIC IN THE DRAINAGE AREA MAP APPENDIX . BASIN REFERENCE No. 8 IS A PRIMARY DRAINAGE SYSTEM AND IS INCLUDED IN THE "SPECIAL DRAINAGE BAS I N AND CHANNEL REACH DESIGN STANDARDS SECTION OF THE COLLEGE STATION DRAINAGE POLICY AND DESIGN STANDARDS , PAGE II AND A MINIMUM FINISHED FLOOR ELEVATION IS REQUIRED OF THREE FEET ABOVE BASE FLOOD . PROPOSED DRAINAGE : • RESIDENT I AL AREA: THE STORM RUNOFF WILL BE HANDLED BY ROUTING IT THROUGH THE STREETS WHICH WERE DESIGNED FOR THE 10 YEAR STORM EVENT AND INTO A PROPOSED UNDERGROUND DRAINAGE SYSTEM WHICH WAS DESIGNED FOR THE 10 YEAR STORM EVENT . THE 100 YEAR STORM EVENT WILL BE HANDLED IN THE RIGHT-OF-WAYS . THE DRAINAGE SYSTEM WILL DISCHARGE INTO THE NORTH FORK OF LICK CREEK . THE DRAINAGE SYSTEM WAS DESIGNED TO INSURE THAT NO INCREASE IN STORM RUNOFF WILL BE RELEASED TO THE SOUTH OF THE DEVELOPMENT . BRIDLE GATE ESTATES -DRA INAGE REPORT -PAGE I OF 3 PAGES • LONGMIRE DRIVE: WITH THE SMALL DRAINAGE AREA, A NATURAL HIGH POINT AND THE SLOPE OF THE LAND NO STORM SEWER WILL BE REQUIRED ALONG LONGMIRE DRIVE FOR THIS DEVELOPMENT . HOWEVER WHEN LONGMIRE DRIVE IS EXTENDED SOUTH BEYOND THIS DEVELOPMENT A DRAINAGE SYSTEM WITH STORM SEWER AND POSSIBLY DETENTION BASIN WILL BE REQUIRED. • COMMERCIAL : THE PROPOSED 1.4 ACRE COMMERCIAL SITE WILL CONSIST OF A 5000 SQUARE FOOT BUILDING, PARKING LOT AND THE ASSOCIATED INFRASTRUCTURE . THE STORM RUNOFF WILL BE ROUTED THROUGH THE PARKING LOT TO THE DRAINAGE DITCH ALONG THE STATE HIGHWAY No . 6 FRONTAGE ROAD. THIS DITCH WILL BE IMPROVED DUE TO THE INSTALLATION OF A CULVERT AT BRIDLE GATE DRIVE . THE DITCH IMPROVEMENTS WILL PROVIDE A DRAINAGE PATHWAY TO LICK CREEK AND THERE WILL BE NO NEED FOR DETENTION ON THE COMMERCIAL SITE. • STATE HIGHWAY No. 6 FRONTAGE ROAD : THE CULVERT AND IMPROVEMENTS TO THE DITCH ALONG THE FRONTAGE ROAD ARE DESIGNED FOR THE 25 YEAR STORM EVENT WITH THE HEADWATER REMAINING WITHIN THE IMPROVED DITCH. THE PHYSICAL DESIGN AND SPATIAL PLACEMENT OF THE STRUCTURE COMPLIES WITH TEXAS DEPARTMENT OF TRANSPORTATION REQUIREMENTS . A MODEL OF THIS CULVERT WAS PREPARED FOR REVIEW, SEE THE MISCELLANEOUS STRUCTURES APPENDIX. • LICK CREEK : To DETERMINE A MINIMUM LOT ELEVATION AND TO ASSURE THERE ARE NO LOTS IN THE FLOODPLAIN AND TO DETERMINE A TAILWATER ELEVATION FOR THE STORM SEWER SYSTEM AN ANALYSIS OF LICK CREEK WAS PERFORMED USING THE HAESTAD METHODS VERSION OF HEC-RAS . ALSO AN ANALYSIS OF THE WATER SURFACE ELEVATION WAS PERFORMED USING HAESTAED METHODS FLOWMASTER PROFESSIONAL PROGRAM . A SECTl ON WAS PREPARED USING THE CROSS SECTION FROM THE HEC-RAS MODEL WHICH SHOWED PREDEVELOPMENT CONDITIONS . A SECOND SECTION WAS PREPARED WHICH SHOWED POST DEVELOPMENT CONDITIONS. THE INCREASE CAUSED BY THE DEVELOPMENT WAS 0. 06 FEET. • EROSION AND SEDIMENT CONTROL : EROSION AND SEDIMENT IS ADDRESSED BY SILT FENCING, HAY BALES AND THEIR MAINTENANCE AS SHOWN ON THE STORM WATER POLLUTION PREVENTION PLAN INCLUDED IN THE CONSTRUCTION PLANS . BRIDLE GATE ESTATES -DRAINAGE REPORT -PAGE 2 OF 3 PAGES CONCLUSION: THE PROPOSED STORM DRAINAGE SYSTEM IS DESIGNED TO HANDLE THE INCREASED RUNOFF FOR THE DEVELOPMENT AND ROUTE IT DIRECTLY TO A PRIMARY CHANNEL WITH NO DETRIMENTAL EFFECTS ON DOWNSTREAM PROPERTY OWNERS .

Box 9960 College Station, TX 77840 979-693-3570 Re: BRIDLE GATE ESTATES PHASE TWO ENGINEERING REVIEW COMMENTS No. 1 1. Sheet 1: Please note, plans show existing sewer line section. If this line is NOT in this location, elevation, slope, etc, provisions will need to be made to redesign sewer line to meet TCEQ/ City requirements. o Yes, there is an existing water and sewer line crossing Bridle Gate Drive that was installed during phase one. I added additional detail and notes for the Contractor, see Sheet 1. 2. Sheet 1: include air relief on water line at high point. o There is a fire hydrant at the high point that can be used to release air in the system. 3. Sheet 1: due to proximity of water line to ROW, the fire hydrant should be designed with a horizontal 90-deg ell so that it is not in a private yard. o This is a "Type One" fire hydrant and it has a 90-degree bend in the make-up. Also with the additional 5 foot PUE there should be plenty of room for the hydrant. 4. All infrastructure within 5-ft ofroadway is required to have structural fill embedment. Please add detail depicting structural fill areas and structural fill embedment details. If cement-stabilized sand is specified, include detail. o The water and sewer lines are 6 feet from the back of curb. I added a note in the in the cul-de-sac stating that it would require a structure backfill. I included a note in the water and sewer details giving the Contractor the option of either a 95 percent modified compaction or a "flowable backfill". 5. Add 2-in sand cushion to sidewalk detail. o Please see detail, Sheet 3. 6. Note states "All sewer services shall be 6-in dia. And made of the same material as the sewer main." Detail on Sheet 3 shows 4-in service lines. Service lines are required to be SDR-21 or SCH 40. o The 6" diameter note was revised to read all services will be 4" inch. I also added in the note that the material will be SDR-21 or SCH40 plastic pipe. 7 . Show stationing of sewer laterals. o Please see Sheet 1. Additional: o I added additional information to the NPDES plan and a note on the plan and Sheet 1 about the Contractor being responsible for the inspection and maintenance of the SWP3 program. o I removed a note on Sheet 1 about the Contractor filing an NOi. Please review the information and call with question or comments.
