County officials Tuesday convened in Huntington Beach to celebrate the revitalization of a 1-mile segment of a flood control channel, a vital first step in a $250-million collaboration with federal partners to reduce Orange County’s flood risk.

During an on-site news conference near a portion of the East Garden Grove-Wintersburg channel north of Warner Avenue, between Goldenwest and Springdale streets, Orange County Board of Supervisors Vice Chair Andrew Do explained the significance of the project.
