The City is soliciting Request for Proposals (RFP) from qualified firms for the purchase of an integrated software, hardware and service solution to parking citation issuance and on-street payment system. These systems will replace and/or improve the City’s current parking enforcement and on street parking systems. The City’s existing parking enforcement equipment has reached the end of its service life and the on-street parking meters do not adequately provide for various methods of payment desired for optimum customer service.
