Annual Water Main Replacement Project


For the month of December, 2020 the contractor will be connecting newly installed water main and services on Idaho Avenue between 23rd Street and 25th Street and on Santa Monica Place South between 26th Street and Princeton Street, which will require shut-off of the water. Notices will be handed out to affected properties informing them of the date and time that their water service will be shutdown. Traffic on Idaho Avenue at 25th Street will be reduced to one lane and on Santa Monica Place South will be closed to  through traffic. Please use alternate routes whenever possible. If you have any questions or concerns, please contact Carlos Rosales at (310) 458-8721, x2620.
