The Smith Canal levees are highly encroached upon. Due to the amount and nature of the existing certification issues (encroachments, right-of-way issues, access problems, etc.) it was determined that improvements directly to the Smith Canal levees would not be an option. A more feasible solution being considered is the construction of a closure structure near the mouth of Smith Canal. The closure structure is an inflatable barrier that would close only during flood events and would remain open at other times to allow the passage of boats.

SJAFCA is partnering with Reclamation Districts 828 and 1614 to develop technical information on the Smith Canal closure structure and to obtain FEMA’s concurrence that the closure structure will be accredited as providing the required flood protection.

The closure structure will be composed of a dual sheet pile wall, a gate opening with an inflabable Obermeyer gate to maintain navigation, levee modifications, and facilities to allow storm water passage.
