ST8201-CS 890103 (2) GINN, INC. January 3, 1989 CONSULTING ENGINEERS Mr. Russell R. Doyle, P.E. City Engineer City of Coppell P.O. Box 478 Coppell, Texas 75019 Re: Denton Tap Road Improvements from Belt Line Road to Sandy Lake Road - Water on the Roadway at the Sandy Lake Rd. intersection. Dear Mr. Doyle: As requested in your November 14, 1988 memo, copy attached, we have reviewed the existing paving and drainage facilities in the southeast quadrant of the Sandy Lake Road/Denton Tap Road intersection. It appears that the most practical and least expensive solution to eliminating most of the flow of sprinkler water out of the most northerly driveway from Town Oaks Centre onto and across the northbound lanes of Denton Tap Road is to construct inlets in the driveway as shown on the attached marked print and tie them into the existing storm sewer system as shown. We recommend that the work depicted on the attached print be included in the scope of work of the current Contract for the Denton Tap Road Improvements from Belt line Road to Sandy Lake Road. The approximate construction cost of this work is $6,000.00. This item can be charged to the contingency fund in the project budget, copy attached. Due to the fact that the work will have to be done on private property, it will also require that two drainage easements be acquired. Unless directed otherwise, we will proceed to prepare the necessary drainage easements. Upon receipt of the easements, we will add the necessary inlet to the project. We trust this meets with your approval. S incerely~, ~/~~_ Jo~n~C¢~ Karlsruher, P.E. Project Engineer enclosures cc: H. Wayne Ginn, P.E.
