Proposals and accompanying information received from proposers shall be and remain confidential, and shall not be construed to be public records, until full and final completion of the procedures specified in Section 13.10.650 of this article. In the event that a proposer claims that information submitted with a proposal is or contains proprietary information, confidential information, or information which constitutes a trade secret, the proposer shall clearly mark "confidential" on that portion of the proposal claimed to be proprietary, confidential, or trade secret information. In the event that the city receives a request made pursuant to the Public Records Act for such information, the proposer shall execute an agreement meeting the approval of the city attorney, which provides for defense and indemnification of the city in any action brought pursuant to that Act. If the proposer fails to execute such an agreement within the time specified by the city attorney, the material shall be deemed to be a public record.
