Park districts on both sides of the Bay are following the state’s lead and closing parking lots at local beaches and parks in a bid to prevent overcrowding conditions favorable to the spread of the coronavirus.

Last weekend, beaches and parks throughout California saw record crowds despite Gov. Gavin Newsom’s urgent instructions to stay at home as much as possible and keep at least six feet away from others when venturing outdoors for exercise. The state parks department responded by closing parking lots at the various locations it oversees.
