In the past two weeks I have driven to the following Riveside locations and parked without issue:
Biscottis - Parked directly across the street on St Johns
Ooh La La Nail - Parked in front of Mojo's on St Johns
Tapas That - Parked at Lomax and Oak
Bark - Parked in front of Hawthorne Salon
Alpha Dog - On Park directly across the street
These were all at different times of the day, weekends and weekdays. There was no hassle parking at any of these places despite the "parking problems" that plague Riverside.
