Update on Beach Re-Noursihment Project

Regarding Beach Re-nourishment

Dear Friends

As promised below please find an update with respect to the Charlotte County Erosion Control Project (aka beach nourishment and Stump Pass maintenance dredging). The Project includes three elements: beach renourishment, maintenance dredging of Stump Pass, and installation of the Terminal Groin on the south end of Manasota Key. The projected construction cost of the Project was $8.2 Million. The Project was bid on June 16, 2016. Two contractors submitted bids on  August 10, 2016. The bids were $13.9 Million and $14.5 Million; significantly greater than anticipated. The two contractors bid the job to bring their offshore dredge equipment from Louisiana and Virginia with mobilization costs of $4.3 Million and $5.2 Million, respectively. 

The County and Consulting Team conducted an analysis of the beach segments within the Project area. The South Beach Fill, i.e., the gulf-front shoreline along Knight-Bocilla-Don Pedro Island retains approximately 97% of the design beach fill template affording the recreation, environmental, and storm damage reduction benefits. Attached is the detailed analysis.

Due to the bids exceeding the budget by over $5 Million, and because the South Beach Fill demonstrates outstanding performance, the County is rebidding the Project to complete the Stump Pass maintenance dredging and terminal groin components of the Project in 2017, and phasing the South Beach Fill renourishment to coincide with the design renourishment interval of 8 years in 2019. This will coincide with the Manasota Key beach restoration project, allowing the County to construct both segments under one mobilization effort, that should save the residents, stakeholders, and taxpayers over $5 Million.

The County has the right to move forward with beach renourishment in the event conditions change along the South Beach Fill, and will be monitoring the beaches routinely.
Please share this information with your friends, residents, and stakeholders.
