Park West CC(1)-CS 901022 GINN, INC. October 22, 1990 / Ms. Shohre Daneshmand/ P.E. city of Coppell / P.O. Box 478 / Coppell, TX Re: ~ Com~e~ce Center Co~truction ~lans CONSULTING ENGINEERS Dear Ms. Daneshmand: We have reviewed the revised construction plans for the above referenced project for general conformance to the City of Coppell ordinances and standards. We reviewed the marked-up plans and prior comments made by Ginn, Inc. to see if the engineer addressed all items as requested. The following are our comments. The sidewalks will be constructed when the Director of Public Works deems necessary, not when the majority of property owners want them as the note on Sheet 1 states. Southwestern Boulevard Drive plans need to be coordinated with these plans since there are references to same throughout. (We do not have any plans for Southwestern Blvd.) Waterline "E" should be upgraded to 16" diameter not 12" as shown. This is due to a recent hydraulic analysis for the city of Coppell. Participation by the City will be in accordance with the subdivision ordinance. The waterline profiles have been provided as requested. Sanitary sewer lines are provided also. The upgrading of the 10" sanitary sewer to 12" along Airline Drive from International Drive to Belt Line was not done. The engineer indicated that the loads on the sewer line were reduced by diverting flows southward to Wrangler. If the loading justifies this, we have no objections. Line "K" in Wrangler Drive should be 12" all the way. It indicates 10" between International and Executive Drives. 6. On sanitary sewer profiles, please indicate of mains and velocities. flow capacities 17103 Preston Road · Suite 100 · LB II8 · Dallas, Texas 75248 · Phone 214/248-4900 At Wrangler Drive and International Drive (Sheet 40), it appears the low point (Sta. 23+00) and the location of the inlet (Sta. 22+25) are not the same point. Engineer must address. To the best of our knowledge and belief all items identified in our June 1, 1990 review have been addressed, shown, modified or changed as requested. The standard detail sheets should be attached to the drawings. We are reviewing the "water study" at this time and will have comments at a later date. Should you have any questions, please contact our office. Sincerely, Gabe Favre GF/dsp cc: Steve Goram Don Davis Prentiss/Copley H. Wayne Ginn, P.E. File 90441
