Why this matters
The new system will be the main feed for treated water for residents in the La Jolla and Pacific Beach areas.
Expect upcoming road closures and construction near SeaWorld — a $123 million project to update a water transmission system near the theme park and through Mission Valley begins this summer.
About 10 miles of water mains will be constructed between Interstate 805 and Sea World Drive, mainly on Friars Road, according to a city presentation. The city’s Active Transportation and Infrastructure Committee — made up of four city councilmembers — last week unanimously voted to move forward with hiring OHLA USA Inc. to begin construction.
Along with water main updates, the project will also include street resurfacing, installation of pedestrian curb ramps, and bike lane improvements along Sea World Drive and Friars and Fashion Valley roads.
Staff said once completed, the new system will be the main feed for treated water to the La Jolla and Pacific Beach areas and will relieve the existing Kearny Mesa pipeline. It’s also expected to “provide supply flexibility” for neighborhoods served by the Alvarado and Miramar water treatment plants.
According to a contractor agreement, the first of six phases of construction will include potholing, videotaping of existing conditions, and installation of minimum water mains.
Officials said delays have extended the project’s schedule. Bike lane improvements and street resurfacing are scheduled to begin in December 2027. Construction is expected to last until winter 2028.
