The cities of Inglewood and Culver City are expected to file lawsuits on Thursday aiming to halt the $11 billion renovation of Los Angeles International Airport.

The suits, coming on the heels of El Segundo’s lawsuit on Monday, are part of a broadening effort to block Los Angeles Mayor James Hahn’s plan to modernize the facility. Separately, the citizen’s group Alliance for a Regional Solution for Airport Congestion also planned to file a suit.

Each of the lawsuits, expected to be filed in Los Angeles Superior Court, allege that the project’s environmental impact report does not meet state requirements. Among the biggest complaints: that the EIR did not adequately address the project’s impacts on noise levels, air pollution, traffic and safety in surrounding communities.

Alternative plans for the project were not considered, claims Jan Chatten-Brown, principal of Santa Monica-based Chatten-Brown & Associates, which is representing the Alliance for a Regional Solution for Airport Congestion.

“We think (the EIR) is very flawed both in the manner which they adopted it and substantively in the failure to provide a regional solution to our airport congestion,” Chatten-Brown said.
