On April 22, 2012, City Council approved the professional services agreement with AECOM Technical Services, Inc. for restoration of the Interurban Channel (north of FM 517), and Nottingham Ditch (Calder Rd. to the Interurban Channel).

A scope of work to implement the abandonment has been prepared to supplement the original contract. The amended scope of work will include a need for redesign as outlined in the attached AECOM proposal.
AECOM has determined that the time required to complete the redesign of Nottingham Channel shall be six (6) weeks. Based on this time frame and the tasks detailed within this scope of work, AECOM requests a lump sum fee of $81,180.26 for engineering services as shown in the table below.
