I had lost track of the bike share parking requirements, but found the City of Sacramento has a good bike share page now that answers most questions you might have, at http://www.cityofsacramento.org/Public-Works/Transportation/Programs-and-Services/Bicycling-Program/Bike-Share.
People have asked whether you have to lock the bike to a bike rack, and the answer from the page is yes, you do.
They have also asked what to do about improperly parked bikes. The page says to call 311, and they must be removed within two hours of notice to the vendor, JUMP in this case. I’m still going to recommend that you first report to JUMP by emailing firstname.lastname@example.org, and report to the city if the issue is not solved in a timely manner. Some people have reported that 311 operators said it was not an issue to report to them, so there is some education yet to happen, but with the system only three weeks old, not all the bugs have been worked out yet.
