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

The City Program Manager, or his designee, will be the main point of contact to facilitate the

If the City determines that a response to questions is necessary for clarification, then a response

will be issued in writing as an addendum for the benefit of all interested consultants. The City

will not respond to questions received less than (72) hours prior to the proposal submission

deadline, as this does not provide prospective consultants enough time to make modifications to

their proposals. The City will not respond to questions with verbal clarification; all City

responses to questions shall be in writing.
