Hahamongna's Fate: It's Up to You . . . and the County Supervisors

The County Flood Control District has now released their revisions to the Final Environmental Impact Report for their Big Dig mining and trucking operation in Hahamongna. They have made some minor concessions, but the worst parts of their program are still there: 1) its too big; 2) too fast; and 3) too destructive to habitat, our air quality, traffic and neighborhoods.

There is now a 45 day review period which extends from today until September 7th. We urge you to state your views on the revisions and the overall program itself.

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 (CEQA). 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.

We're Coming Down to the Final Decision — Your Action Now is Critical: Please Support the No Big Dig Lawsuit!
