It is $3.00 an hour. I have the app but if I use it since its tied to my CC it forces me to pay for a minimum of 2 hours. But if you take change or a few dollar bills you can pay at the pay station for shorter time periods. I was in a hurry so I stayed about 40 or 45 minutes for $1.50. I know they are also capping all parking in public lots at $10 for the entire day due to Covid.
If you park in the district and walk over to the beach.
Hard to tell, the area is very crowded.
