Document Description
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. The Project would alter two adjacent reaches of the channel. Project work in Reach A (conveyance improvements) would increase the capacity of the conveyance system between West Tenth Street and West 8th Street, Project work in Reach B (desilting) would desilt the channel from around West 8th Street to approximately 200 feet north of the BNSF railroad trestle to restore design capacity. Either reach can be improved independently from the other or concurrently, but work in both reaches must be completed to realize improved levels of flood protection.
