ST0701-CS080221(8/2612009) Keith Marvin -Southwestern Blvd. From: "Smith, Madonna" <msmith@Halff.com> To: <kmarvin@ci.coppell.tx.us> CC: "Littleton, Dave" <dlittleton@halff.com> Date: 2/21/2008 2:37 PM Subject: Southwestern Blvd. Attachments: 0001-SP-alt-24732-2. pdf Keith, Attached is a schematic plan and profile of Southwestern Blvd. at Grapevine Creek. What we have shown is the proposed alignment west of the creek and the trees that will be spared and a few that will need to be removed. The profile shows the proposed pavement connection to the existing bridge at elevation 510.00 and the approximate pavement connection to a proposed bridge elevation of 513.00. We need to schedule a utility coordination meeting with Oncor, Atmos and Verizon. Do not hesitate to contact me or Dave Littleton with questions or concerns. Thank you, Madonna Smith, P.E.
