Ongoing Improvement Projects in RHE

Post Date:10/22/2018 9:15 AM

As improvement projects continue in Rolling Hills Estates, residents may have noticed the various construction crews working throughout the City. Three of these four major projects are in some way repairing the water infrastructure in RHE, ensuring that our area has safe and reliable running water for many years to come and clear drainage channels for the conveyance of storm water. The other major update was to our roads, thanks to two street resurfacing projects that re-paved segments of Hawthorne Boulevard and Silver Spur Road, as well as various residential streets earlier this year. Read on for more information on each of these projects. 

Palos Verdes Peninsula Water Reliability Project
California Water Service (Cal Water) is in the fourth month of construction on the Palos Verdes Peninsula Water Reliability Project. So far more than 12,000 feet of pipeline have been installed. This important project will replace the Peninsula’s aging water infrastructure and ensure that all Palos Verdes residents continue to have safe, reliable water service everyday and in the event of an emergency. 

Cal Water has completed pipeline installation on the Dapplegray Elementary School property and Palos Verdes Drive North between Dapplegray Elementary School and Palos Verdes Drive East. Work continues on Palos Verdes Drive North between Palos Verdes Drive East and Montecillo Drive and will soon begin on Montecillo Drive from Encanto Drive to Palos Verdes Drive North. Construction work is in progress along the Palomino Ranchos Bridle Trail between Rolling Hills Road and the Rolling Hills Little League ballfield.

The Palos Verdes Reservoir, built in 1939, is key water storage infrastructure for Southern California. The reservoir is under construction for necessary repairs to its liner and floating cover. The work is being done by the Metropolitan Water District and is expected to be completed by late 2018/early 2019. Below is an outline of current and remaining activities:

  • Replacement of the reservoir liner is 100% complete and installation of the reservoir cover is currently underway. MWD’s work crew expects to inflate the reservoir cover at the end of October to check for holes.
    • Please note that the cover inflation will take place in the early morning hours. Adjacent residents will be notified prior to the inflation.
  • Starting November 5, construction will begin to install a new valve at Encanto Drive and Montecillo Drive.
    • This work will take place over approximately two days and will include overnight construction. Nearby residents will be notified prior to the project starting.
  • In January, bulkheads will be removed at the pipe inlet structure adjacent to George F Canyon to allow water to flow back into the reservoir.
    • This work will take place during regular working hours. Nearby residents will be notified before construction begins.
  • The reservoir will be filled in early 2019. This process includes flushing the reservoir with water, disinfecting it, dechlorinating the water so it does not impact ocean life, and sending the disinfected water to the storm drain. This process requires the construction of a pipe over Carriage Trail to connect to the storm drain system. This will require that the trail be closed for a few days while MWD lays the pipe and regrade the trail to cover the pipe. MWD will need to close the trail again to remove the pipe and restore the trail. The construction work in the trail will take place in late 2018 or early 2019.
    • Equestrians and local residents will be updated on the project timing and necessary signage will be put up for trail users.

Storm Drain Repairs
The City is currently in the process of completing storm drain pipe repairs at 11 locations. This is the first year in a four-year work program to reline 45 “priority” storm drains that have been identified for repairs. Relining storm drains ensures integrity of the system and supports clean and efficient drainage to outlets. The cost to repair and reline these 11 storm drain pipes is approximately $400,000, funded with General Funds.

Street Resurfacing Projects
Earlier this year, the City of Rolling Hills Estates completed a street resurfacing project that included repaving a section of Silver Spur Road and the residential streets of Deerhill Drive, Harbor Sight Drive, Spinning Wheel Lane and Sweetgrass Drive. The project also included isolated pavement repairs on Conestoga Drive, Estribo Drive, Gaucho Drive and Saddle Road. The total cost of the project was about $1.2 million.

In addition, over the summer the City repaved a portion of Hawthorne Boulevard and the residential streets of Bluemound Road, Elmdale Drive, Latigo Lane, Kingspine Road and Rollingwood Drive. A street depression on Palos Verdes Drive North near Lazy Creek Lane was also repaired. The total cost of this project was approximately $1 million.

Both street resurfacing projects were funded with a combination of SB 1, Proposition C, Measure R, Measure M and General Funds.
