City of Coppell Engineering Dept. P.O. Box 478 Coppell, Texas 75()19 Reference: Forest Cove Estates, Phase 1 Coppell, Texas Dear Mike: We have addressed all the comments in you letter dated October 8, 1997 with exception to the following: Item ~f~ As was discussed with Atul Patel, deletion of the TC grades was also acceptable. Item #12 A 1/4":1 slope is provided for the sidewalk. Item #13, 14 The drainage bar ditch reaches its high point about 130 feet west of Forest Bend. We are filling the bar ditch so the water sheets across the intersection Item #19 As was discussed with Atul, since the preliminary plat was approved without this connection and since more than adequate circulation is being provided off Sandy Lake Road, this request was deleted. Item #22 The existing waterline was field located and is south of the south edge of pavement on Sandy Lake Road, therefore, boring is not necessary. Item #26 The existing pipe under Coppell Road is undersized. The lots which back up to Coppell Road are elevated so that the flow will go over the road prior to backing up into the Iots.,,,This was a pre-existing condition which we had no control over. Item #27 As we discussed with Atul, the City of Dallas criteria allows 15 minute time of concentration and an "1" value of 9.6 inches per hour. We have added a grade to drain at the end of alley A-1 and the appropriate erosion control. Corte~ & Burgess, Inc. 7950 E ,pbro, ok Scite 250 D;ii.~s.
