Is there not a way for the city to hire experienced staff to manage this themselves?
The City already has parking enforcement staff that enforces public parking policies.
I work in Riverside and I'm in San Marco often and I'll frequently see the same car parked in the same spot for the entire day into the night. Perhaps parking meters will cycle people out and allow new customers to park?
Technically, on-street parking in Riverside and San Marco commercial areas are free for two hours. After that, a citation can be issued. There is nothing stopping public parking enforcement personnel from enforcing these policies now.
Revenue collected from City-owned parking garages, metered parking and other various parking citations (which primarily consists of handicap parking violations since existing two-hour parking is not presently enforced in practice) is held in a specific fund for capital-related improvements. There is presently enough money in that fund to upgrade meters or invest in other technologies to assist enforcement and other parking management related strategies.
Since the present mayoral administration made personnel changes in the management of public parking five years ago... revenues have been declining year-over-year... suggesting that there is a serious management problem that can be easily fixed- not some systematic issue that only private industry can solve.
