A developer wants to build a $1.4 billion desalination plant to turn seawater into drinking water off the shore of Huntington State Beach.

The California Coastal Commission is expected to vote Thursday on the Poseidon Water plant, which would be built near Pacific Coast Highway and Magnolia.

“The site in Huntington Beach is a perfect site for sea water desalination,” said Jessica Jones, director of communications at Poseidon Water, a U.S. seawater desalination developer.
