DRAINAGE BASIN: White Creek VALID FOR 24 MONTHS CONTRACTOR: TYPE OF DEVELOPMENT: Full Development Permit CONDITIONS: 1. No work beyond limits covered in permit is authorized. 2. The permit may be revoked if any false statements are made herein. If revoked, all work must cease until permit is re- issued. 3. The permit will expire if no significant work is progressing within 24 months of issuance. 4. Other permits may have been required to fulfill local, state and federal requirements. Construction will be in compliance with all necessary State and Federal Permits. 5. Stormwater mitigation, including detention ponds will be constructed first in the construction sequence of the project. 6. In accordance with Chapter 13 of the Code of Ordinances of the City of College Station, measures shall be taken to insure that all debris from construction, erosion, and sedimentation shall not be deposited in city streets, or existing drainage facilities. Construction Site Notice or Notice of Intent (NO[) along with Stormwater Pollution Prevention Plan (SWP3) will be kept and maintained on-site during construction as per TPDES permitting requirements. If it is determined that the prescribed erosion control measures are ineffective to retain all sediment on-site, it is the Contractor's responsibility to implement measures that will meet City, State, and Federal requirements. 7. All disturbed areas will be re -vegetated prior to Letter of Completion or Certificate of Occupancy. 8. All trees required to be protected as part of the landscape plan must be completely barricaded in accordance with the Landscaping and Tree Protection Section of the City's Unified Development Ordinance, prior to any operations of this permit. The cleaning of equipment or materials within the drip line of any tree or group of trees that are protected and required to remain is strictly prohibited. The disposal of any waste material such as, but not limited to, paint, oil, solvents, asphalt, concrete, mortar, or other harmful liquids or materials within the drip line of any tree required to remain is also prohibited. 9. All construction shall be in accordance with the stamped approved plans and specifications for the above-named project and all of the codes and ordinances of the City of College Station, as well as State and Federal Regulations that apply. Only those deviations from BCS Unified Design Guidelines, Specifications and Details specifically requested and approved will be allowed. 10.

MITCHELL €I r-. MORGAN Erika Bridges June 10, 2013 City of College Station P.O. Box 9960 College Station, Texas 77842 RE: Lakeridge Replat — Fire Flow Analysis Corrections Dear Erika, Submitted on May 28, 2013 was a fire flow analysis for the proposed eight (8) inch waterline that we are constructing to Lot 2, Block 1 of the Lakeridge Living Subdivision. That fire flow analysis made the following assumptions: • The building will NOT be sprinklered and will be approximately 7,200 SF in size. • The building type will be Type II -B construction and the maximum fire flow demand will be 1750 gpm. The following corrections were made to the initial fire flow analysis assumptions and the model simulated: • A proposed domestic peak demand of 84.6 gpm was added for the commercial building. The attached simulation shows that with the corrected assumption the waterlines perform within the City design guidelines. Pipes 4035 and 4046 are closed in this fire flow simulation run, which simulates a single feed to Lot 2, Block 1 of the Lakeridge Living Subdivision and does not take into account any improvements from the subdivision. Per Table B105.1 and C105.1 in the Fire Code, this size and type of construction requires a fire flow of 1750 gpm. This fire flow along with the 84.6 gpm domestic demand is placed on node 59340 which is the fire hydrant location. The maximum velocity occurs in line 3996, 4044 and 4045 and is 11.71 fps. The minimum pressure at the fire hydrant occurs at node 59340 and is 54.65 psi under fire flow conditions. Both of these parameters (velocity and pressure) are within proper design guidelines as the velocity is below the maximum 12 fps and the pressure is above the minimum 20 psi requirement during fire flow.

Box 9960 College Station, Texas 77842 RE: Lakeridge Replat — Fire Flow Analysis Corrections Dear Erika, Submitted on December 3, 2012 was a fire flow analysis for the proposed eight (8) inch waterline that we are constructing to Lot 2, Block 1 of the Lakeridge Living Subdivision. That fire flow analysis made the following assumptions: • A small convenience store and gas station will be constructed on that lot. • The building will be fully sprinklered and will be approximately 7,000 SF in size. • The building type will be Type V -B construction and the maximum fire flow demand will be 1500 gpm. The following corrections were made to the initial fire flow analysis assumptions and the model simulated: • The building will NOT be sprinklered and will be approximately 7,200 SF in size. • The building type will be Type II -B construction and the maximum fire flow demand will be 1750 gpm. The attached simulation shows that with these corrected assumptions the waterlines perform within the City design guidelines. Pipes 4035 and 4046 are closed in this fire flow simulation run, which simulates a single feed to Lot 2, Block 1 of the Lakeridge Living Subdivision and does not take into account any improvements from the subdivision. Per Table B105.1 and C105.1 in the Fire Code, this size and type of construction requires a fire flow of 1750 gpm. This fire flow is placed on node 59340 which is the fire hydrant location. The maximum velocity occurs in line 3996, 4044 and 4045 and is 11.17 fps. The minimum pressure at the fire hydrant occurs at node 59340 and is 56.06 psi under fire flow conditions. Both of these parameters (velocity and pressure) are within proper design guidelines as the velocity is below the maximum 12 fps and the pressure is above the minimum 20 psi requirement during fire flow. 511 UNIVERSITY DRIVE EAST, SUITE 204 COLLEGE STATION, TX 77840 974 760.6963 979.260.3564 r; ihPI:Ai��-.:0--::Y „"l 17, ❑;,i _ f4�S ,I .,. you have any questions please do nn to to call. y�P�E OF .. x.I++++ ncerel VERONICA J.B.
