The City of Patterson is accepting proposals from qualified firms to provide professional water

completed under the retainer agreement a specific service request must be issued for each project,
specifically delineating the requested services, with fees for said services based upon rates
identified in the retainer agreement and in conjunction with a jointly agreeable, negotiated
maximum fee for said services. Should the City fail to successfully negotiate an acceptable
maximum fee for services for a specific project with the Consultant involved, the City reserves
the right to seek and retain said services through other means or contractors.
