Decision Day for Hahamongna: Thursday, March 23rd

The big decision on County Flood's Big Dig Program for Hahamongna Watershed Park will be delivered on March 23 in the Superior Court. In February Judge James C. Chalfant issued a tentative ruling in Arroyo Seco Foundation & Pasadena Audubon Society v. County of Los Angeles, finding that the environmental impact report for the Devil's Gate Sediment Removal Project was critically flawed due to air quality and mitigation program deficiencies.

At the March 23 heaing, Judge Chalfant will review the cumulative impacts of the project and rule on what remedies County Flood must take for the project to go ahead. These could include revisions to the EIR and a re-approval by the County Board of Supervisors.
