$1.6M Loan To Fund Up To 10 More Dewatering Wells In Landslide Area
Up to 10 additional wells will be installed in Abalone Cove area to help dewatering efforts and slow land movement, officials said.
RANCHO PALOS VERDES, CA — Up to 10 additional deep dewatering wells will be installed in the Abalone Cove area with the use of $1.6 million loan from the city.
At Tuesday's City Council meeting, the Abalone Cove Abatement District (ACLAD) outlined a plan to install the wells 250 feet underground to relieve water pressure that is fueling land movement. Locations of the new wells were selected based on proximity to the area's most productive wells, gaps in dewatering areas, expected survivability, drilling access and drainage availability.
"The biggest thing I want to emphasize is the urgency of it. In my opinion, we're three or four months behind in terms of stuff that we're doing at this juncture," Mayor Pro Tem Paul Seo said. "We're reenergizing Seaview and other places and we don't have anything done at ACLAD."

Dewatering wells already installed in the Portuguese Bend landslide complex have been highly productive and have removed more than 112 million gallons of water from underground. To date, the city has allocated $14.7 million for the emergency dewatering well program through the end of March 2025.
