The Livermore Area Recreation and Park District has adopted an ordinance that links the open hours for parks and other districts facilities to the rising and setting sun, rather than the clock.

The new ordinance, which goes into effect July 24, set the hours of operation for all district facilities, parklands and trails from sunrise to a half hour after sunset, except for lighted sports facilities that are open 10:30 p.m.

Under the current ordinance, parks and trails are closed from 10 p.m. to 6 a.m.
