Item 5CCity of Southlake, Texas MEMORANDUM June 17, 2003 To: Billy Campbell, City Manager From: Pedram Farahnak, P.E., Director of Public Works, 481 -2308 Subject: Approval of final construction payment for Dove Road widening from SH 114 transition to the Kirkwood Boulevard intersection in the amount of $369,677.49. Action Requested: Approval of the final construction payment for Dove Road widening from SH 114 to Kirkwood Boulevard, completed in conjunction with the Verizon Wireless developer's agreement in the amount of $369,677.49, $95,322.51 below the budget. Background Information: On September 10, 2002, the City Council approved a developer's agreement with Verizon Wireless that required the developer to widen Dove Road from SH 114 through the intersection at Kirkwood Boulevard. Anticipating minor changes during construction, $465,000 was approved by the City Council, but the developer's agreement allowed $345,686 for reimbursement. During the construction, it was determined that additional pavement markings and signage was needed to better control traffic flow and that paving the raised median with concrete pavers similar to what TxDOT had done at SH 114 would eliminate continuous maintenance of the median, as it was designed to be left with grass between the curbs. The final construction cost is $369,677.49. The FY 02/03, Council approved Capital Improvements Bond Program included $465,000 for Dove Road widening from SH 114 to Kirkwood Boulevard. Financial Considerations: Funds are available from the FY 02/03 Capital Improvements Program in the amount of $465,000 of which $369,677.49 is required for this project. Citizen Input/ Board Review: None Legal Review: None Alternatives: The Council may approve or deny it. Supporting Documents: Final Quantities and Cost from Contractor Location Map Staff Recommendation: Approval of the final construction payment for Dove Road widening from SH 114 to Kirkwood Boulevard, completed in conjunction with the Verizon Wireless developer's agreement in the amount of $369,677.49, $95,322.51 below the budget.
