Two groups that recently won a lawsuit against the Los Angeles County Flood Control District over its sediment removal project at Devil’s Gate in the Hahamongna watershed are scheduled to deliver their current positions in a presentation before the City’s Environmental Advisory Commission on Tuesday, August 8, during the Commission’s regular monthly meeting.

The Pasadena Audubon Society and the Arroyo Seco Foundation will present updates on the Devil’s Gate Sediment project Environmental Impact Report and their reactions.

Their report is for “information only”; the Commission is not expected to vote.

In February, Judge James Chalfant of the Los Angeles County Superior Court sent the sediment removal project back to square one when he ordered the county to submit additional proof that its mitigation plan for the project is satisfactory. Chalfant said the EIR’s conclusion saying the project would have less than significant impact on biological resources lacked substantial evidence.

The order was in response to a lawsuit filed by both of the Pasadena-based environment advocacy groups.

The judge also said the EIR did not consider the cumulative impacts of the project on wildlife and rare plants living in the watershed area.

The order did not fully stop the project but gave the county an opportunity to revise the EIR and get it approved by the county Board of Supervisors. He also did not order a reduction of the project’s scope, and left that issue to the county’s discretion.

Just last month, the Flood Control District released their revisions to the final EIR for the Big Dig mining and trucking operation in response to the Superior Court’s order.

There is now a 45-day review period which extends from July 24 when the revisions were released until September 7.

The Arroyo Seco Foundation said looking at the revisions, it still sees the “worst parts of their program” are still there.

“It’s too big, too fast, and too destructive to habitat, our air quality, traffic and neighborhoods,” the Foundation said on a “Stop the Big Dig” website that it maintains with the Pasadena Audubon Society.

“The ultimate decision on the fate of Hahamongna will be made by the County Board of Supervisors, which must act to certify that the entire EIR is in compliance with the California Environmental Quality Act,” the groups said. “This is the time for those who care about Hahamongna to speak with a loud voice telling the Supervisors to Save Hahamongna and ensure that the sediment removal program is reshaped along more sustainable and environmentally-sensitive lines.”

Public comment on matters not on the agenda are allowed after Roll Call at the Environmental Advisory Commission meeting on Tuesday, which starts at 6 p.m.

The Commission meets at the Permit Center Hearing Room at 175 N. Garfield Avenue in Pasadena.
