Project Status as of August 2022

Phase 1: The consultant delivered the 100% design plans on June 14, 2022, which were reviewed and approved by City staff. This project is anticipated to bid in August 2022, but might be delayed to September 2022, pending approval of the USACE Nationwide Permit.

Phase 2: Due to scope revisions in the design of the project that require FEMA approval, the
consultant will deliver 60% design plans upon receiving guidance from FEMA regarding how to proceed. A United
States Army Corps of Engineers (USACE) permit is also needed for this project, which could affect timing. The
consultant and City staff anticipate a Nationwide Permit, which requires 9-12 months to obtain. Public comments
related to the design options were reviewed by the City, and City staff recommended proceeding with plans and
permitting requirements for the repairs of the outfalls. The consultant is currently working with a company called
ShoreSox to provide a demonstration of their channel bank stabilization technique. This technology could possibly
reduce the impact of repairs along Magnolia Creek originally planned for the project. Results of the bank stabilization
repair will be reviewed and a decision on how to move forward with 60% design will be made. The consultant and
City staff have a meeting scheduled with representatives from ShoreSox on August 8 to discuss and see a demo of
the stabilization technique and determine what needs to be included in the revised proposal for the City to obtain
approval to move forward with the sample installation.
