This report will illustrate the hydrology and hydraulic impacts of the proposed development. INTRODUCTION The proposed project is located at the northwest comer of Texas A venue and Park Place. Plans are to construct approximately 8,050 square feet of retail space on 1.071 acres of land. The site was the previous location for Long John Silvers restaurant. PREDEVELOPED CONDITIONS The condition of the site prior to development consisted of a Long John Silvers restaurant on the 1.071 acres. The impervious cover for the site consisted of 0.79 acres comprised of a building , sidewalks and paving. Following is the calculation for the weighted C- value using TxDot Hydraulic Design Manual values for C and time of concentration of 10 minutes is assumed: Cwt = (0.791/1.071)*0.95 + (0.28/1.071)*0.12 = 0.73 4588 H in ton Dr.• Plano , T X 7502 4 • (469) 44 3-086 1 •Fax: (469) 443-0863 • tcca m ey l @comcast.net • Drainage Report Park Place Cross Roads August 1, 2005 Page2 Following are runoff values for the 25 and 100 year predeveloped conditions: C (runoff coefficient) I (intensity -in/hr) A (area -acres) Q (cubic feet/sec) DEVELOPED CONDITIONS 25 Year 0.73 9.9 1.071 7.74 100 year 0 .73 11.6 1.071 9 .06 The proposed retail building will be constructed on 1.071 a~res.

The grate inlet and 15-inch pipe is at a 2.2% slope. The capacity of this pipe is 9 .60 cfs (cubic feet per second). The actual discharge into the pipe is 2.44 cfs and 2.86 cfs for the 25 and 100 year storm event, respectively . • Drainage Report Park Place Cross Roads August 1, 2005 Page 3 The existing 24-inch pipe has a capacity of 24.05 cfs on a 1.13% slope. The actual discharge is 5 .92 cfs and 7 .16 cfs for the 25 and 100 year storm, respectively. The internal drainage will be taken to an existing curb inlet structure on Park Place. The structure will be reconstructed to incorporate a grate to allow water runoff from the curb to enter the structure. RESULTS and CONCLUSIONS The post development runoff is less than the predeveloped runoff by 1.1 7 cfs. The existing internal drainage can accommodate the proposed runoff. The proposed development will not have an adverse impact on the existing drainage system. We trust this provides you with the information needed at this time.

The project includes temporary and permanent erosion control, seeding, sodding, and hydromulching, as required by this SWPPP and as required by the contract plans and specifications. D. HYDROLOGY, SOILS, AND WETLANDS IN AND AROUND SITE The surface soil consists of dark tan clayey sand and silty clay. The soils are moderately well drained. The existing hydrology of the site is shown on the construction plans. The proposed hydrology will be unchanged by this project. According to the National Wetlands Inventory Maps published by the United States Fish and Wildlife Service, the sites are located in primarily upland areas. E . SEQUENCE OF MAJOR ACTIVITIES The order of activities will be : 1. Construct construction entrance 2. Install sediment barriers 3 . Demolish existing buildings and pavement 2 4. Construct sediment basins and maintain storm water pollution prevention devices 5. Rough grade site 6. Install underground utilities 7. Prepare parking area and building subgrades 8. Construction of pavement 9. Final Grading 10 . Completion of onsite stabilization (hydromulch, sodding, landscaping) 11. Remove storm water pollution prevention devices F. AREA OF SITE The area to be disturbed at the site is approximately 1.071 acres. G. RUNOFF COEFFICIENT The predevelopment construction area consists of existing buildings and pavement. The runoff coefficient for predevelopment and post development is 0.73 and 0.62 , respectively. H. EROSION AND SEDIMENT CONTROLS 1. Temporary Stabilization -Temporarily seed or cover stock piles and disturbed portions of the site where construction activity temporarily ceases for at least 21 days -stabilize with temporary seed and mulch (if required) no later than 14 days from the last construction activity in that area. Temporary seeding, fertilizing , and mulching will be done in accordance with standards outlined in the 1993 Texas Department of Transportation Standard Specifications for Construction of Highways , Streets , and Bridges, Item 164 . After seeding, areas specifically identified on the Construction Plans shall be mulched with hay . The hay mulch is to be tacked into place by a disk with blades set nearly straight. 2 . Permanent Stabilization -Disturbed portions of the site where construction activities permanently cease shall be stabilized with permanent sod no later than 14 days 3 after the last construction activity. Permanent seeding, fertilizing , mulching will be done in accordance with the Contract Construction Plans. I. CERTIFICATION OF COMPLIANCE WITH FEDERAL, STATE AND LOCAL REGULATIONS This storm water pollution prevention plan was prepared in accordance with requirements outlined in the Texas Pollutant Discharge Elimination System (TPDES) General Permit No . TXR150000. The City of College Station requires sediment and erosion control measures to be implemented at construction sites. The attached construction plans meet the minimum criteria of the City of College Station. J . MAINTENANCE/INSPECTION PROCEDURES These are the inspection and maintenance practices that will be used to maintain erosion and sediment controls: I . a. All control measures will be inspected at least once every fourteen (14) calendar days and within twenty-four (24) hours of the end of a storm event of0.5 inches or greater. Where sites hav e been finally or temporarily stabilized, where runoff is unlikely due to winter conditions (for example, the site is covered with snow, ice, or frozen ground exists), inspections may be conducted at least once a month. b. As an alternative to the abo ve-described inspection schedule, the inspections may be made at least once every seven (7) calendar days , provided the inspection days are specifically defined and are not discontinued or interrupted. c. In the event inspection schedules outlined inJ.1.a and J.l .b would compromise the integrity of stabilized areas , representative inspections may be performed. 2. All measures will be maintained in good working order; if a repair is necessary, it will be initiated with 24 hours of report. 4 3. Built-up sediment will be removed from silt fences when sediment has reached one- third the height of the fence . 4. Silt fences will be inspected for depth of sediment, tears, to see if the fabric is securely attached to the fence posts, and to see that the fence posts are firmly in the ground. 5. The sediment traps will be inspected for depth of sediment, and built-up sediment will be removed when it reaches 50 percent of the design capacity and at the end of the job. 6. Temporary and permanent seeding and planting will be inspected for bare spots, washouts, and healthy growth. 7. A maintenance inspection report will be made after each inspection. A copy of the report form to be completed by the inspector is attached. 8. An individual will be selected who will be responsible for inspections, maintenance and repair activities, and filling out the inspection and maintenance report. 9. The person selected for the inspection and maintenance responsibility will receive verbal instruction from the Owner. He/she will be trained in all the inspection and maintenance practices necessary for keeping the erosion and sediment controls used onsite in good working order. K. INVENTORY FOR POLLUTION PREVENTION PLAN The materials or substances listed below are expected to be present onsite during construction: 1. 2. 3. 4 . Concrete Detergents Metal Studs Fertilizers 5. 6. 7. Petroleum Based Products Wood Lime 5 L. SPILL PREVENTION -MATERIAL MANAGEMENT PRACTICES The following are the material management practices that will be used to reduce the risk of spills or other accidental exposure of materials and substances to storm water runoff. 1. Good Housekeeping: The following good housekeeping practices will be followed onsite during the construction project: a. An effort will be made to store only enough products required to do the job. b. All materials stored onsite will be stored in a neat, orderly manner in their appropriate containers and, if possible , under a roof or other enclosure . c. Products will be kept in their original container with the original manufacturer's label. d. Substances will not be mixed with one another unless recommended by the manufacturer. e. Whenever possible, all of a product will be used before disposing of the container. f. Manufacturers ' recommendations for proper use and disposal will be followed. g. The site superintendent will inspect daily to ensure proper use and disposal of materials onsite. h . An adequate supply of refuse containers will be available throughout the worksite to reduce build-up or ordinary refuse. 2. Hazardous Products: These practices are used to reduce the risks associated with hazardous materials: a. Products will be kept in original containers. b. Original labels and material safety data sheets will be retained; they contain important product information. 6 c. If surplus product must be disposed of, manufacturers ' or State recommended methods for proper disposal will be followed. 3. Petroleum Products: All onsite vehicles will be monitored for leaks and receive regular preventive maintenance to reduce the chance of leakage. Petroleum products will be stored in tightly sealed containers which are clearly labeled. Any asphalt substances used onsite will be applied according to the manufacturer 's recommendations. 4. Fertilizers: Fertilizers used will be applied only in the minimum amounts recommended by the manufacturer. Once applied, fertilizer will be worked into the soil to limit exposure to storm water. Storage will be in a covered shed. The contents of any partially sued bags of fertilizer will be transferred to a sealable plastic bin to avoid spills. 5. Paints: All containers will be tightly sealed and stored when not required for use. Excess paint will not be discharged to the storm sewer system but will be properly disposed of according to manufacturer 's instructions or State and local regulations. 6. Spill Control Practices: In addition to the good housekeeping and materials management practices discussed in the previous sections ofthis plan, the following practices will be followed for spill prevention and clean-up: a. Manufacturer's recommended methods for spill clean-up will be clearly posted and site personnel will be made aware of the procedures and the location of the information and clean-up supplies. b. Materials and equipment necessary for spill clean-up will be kept in the material storage area onsite. Equipment and materials will include, but not be limited to brooms , dust pans, mops , rags , gloves , goggles , cat litter, sand , sawdust, and plastic and metal trash containers specifically for this purpose. c. All spills will be cleaned-up immediately after discovery. d. The spill area will be kept well ventilated and personnel will wear appropriate protective clothing to prevent injury from contact with a hazardous substance . 7 e. Spills of toxic or hazardous material will be reported to the appropriate State or local government agency , regardless of the size . f. The spill prevention plan will be adjusted to include measures to prevent this type of spill from reoccurring and how to clean-up the spill if there is another one. A description of the spill, what caused it, and the clean-up measures will also be included. M. PROJECT SIGN A project sign will be located at the project site.
