CONSULTANT SELECTION PROCESS
Enclosed is a copy of the City of Antioch’s Consulting Services Agreement. By submitting a
proposal for this work, a firm agrees to comply with all terms and conditions outlined in the

extend it for two additional years at the City’s discretion.

The selected firm will receive a notice to proceed after the City Council has approved their contract.
