No banner shall be installed pursuant to a permit until public works has on file a surety bond or cash deposit so conditioned as to assure that the city shall be reimbursed for any expense that may be incurred by the city in repairing or removing any banner or installation device installed pursuant to the applicant’s permit, in repairing damage to city-owned equipment resulting from the banner installation, or in otherwise enforcing any order, rule, or policy of public works. Upon the face of each application received, public works shall indicate the minimum amount of bond or cash deposit required for the requested permit, which shall be at the reasonable discretion of public works and shall be acknowledged by the applicant. The amount of the bond or cash deposit shall not be less than the amount so indicated. The applicant must provide public works evidence of the removal bond or provide the cash deposit ten days prior to installation of any banner. The unused portion of any cash or other deposit shall be returned to the applicant within thirty days of permit expiration or revocation. (Ord. 3258-12 § 11, 2012.)
