The Project is intended to reduce flooding in the Project area by designing for a 25-year level of protection. Currently within the Project area, the West Antioch Creek channel transitions from structural plate steel arch culverts under West Tenth street, to a concrete-lined ditch covered by wooden planking under a parking lot at 1400 West Tenth Street, to an open concrete-lined ditch adjacent to a carport associated with a neighboring apartment building, to an earthen channel with one concrete-lined segment near 4th Street that continues to north of the BNSF railroad trestle.
