Annual Water Main Replacement Project


For the month of October, 2020 the contractor will be connecting newly installed water main and services on Ozone Avenue between 11th Street and 11th Court, which will require shut-off of the water. The contractor will begin installation of new water main and services on 20th Street between Broadway and Santa Monica Boulevard and on Idaho Avenue between 23rd Street and 25th Street. Residents/businesses will be notified of the date and time that their water service will be shutdown. Traffic on 20th Street will be reduced to one lane. Please use alternate routes whenever possible. If you have any questions or concerns, please contact Carlos Rosales at (310) 458-8721, x2620.
