Outdoor irrigation in San Marcos and nearby communities will be restricted to two days a week starting Tuesday, according to the Vallecitos Water District.

The agency — which also serves parts of Carlsbad, Escondido and Vista, as well as the Lake San Marcos and other unincorporated communities — had limited watering of lawns and other landscaping to three days a week from June through October.

Residents can choose the days they would like to water. The restrictions don’t apply to farmers with agricultural water accounts or nurseries.
