Page 2 of 3 M&E WO#6 Summer 2024 Hydrographic Beach Surveys February 20, 2024 BCC Meeting Task 2: Summer 2024 Sector 4 Physical Monitoring Survey (R-61 to R-64, plus R-60.5, 5 Onshore/Offshore Lines) The Sector 4 Hurricanes Ian & Nicole Dune Nourishment Project is currently in the design and permitting phase and is anticipated to provide dune restoration to approximately 2.8 miles of coastline from FDEP Range Monument 55 to R -Monument 70. This stretch of coastline has not been previously nourished by the County and sustained significant erosional impacts from Hurricanes Ian and Nicole in 2022 leading to the upcoming dune nourishment project. The permit the County is to receive for the Sector 4 dune nourishment project is expected to contain requirements for the County to monitor the physical changes associated with a nourishment project on a semi-annual basis to determine the long-term performance of the project and if infrastructure maybe vulnerable to storm damage. Task 2 includes surveying (approx. 3/4 mile) for the summer semi-annual monitoring of the Sector 4 Hurricanes Ian & Nicole Dune Nourishment Project area. Task 2 totals a lump sum amount of $3,048.00. Task 3: Summer 2024 Sector 5 Physical Monitoring Survey (R-65 to R-91, 27 Onshore/Offshore Lines Sector 5 Beach and Dune Nourishment Project was completed in February 2020. The County is required by the FDEP Permit to monitor the physical changes associated with the nourishment project semi-annually to determine the long-term performance of the project and if infrastructure may be vulnerable to storm damage. Task 3 includes surveying (approx. 4.5 miles) required forthe summer semi-annual monitoring of the Sector 5 Beach and Dune Nourishment Project area. Task 3 totals a lump sum amount of $16,381.00. Task 4: Summer 2024 Countywide Beach Monitoring; (R-92 to R-119, 28 Onshore/Offshore lines) For the shoreline outside of Sectors 3, 4 and 5 project areas, countywide beach profile surveys are necessary to identify areas of chronic beach erosion and determine if infrastructure may be vulnerable to storm damage. The beach profile surveys will then be used to determine appropriate projects to mitigate erosion as identified in the County Beach Preservation Plan, including the upcoming Nourishment Projects. Task 4 includes the remaining countywide (approx. 5.3 miles) beach profile surveys. Task 4 totals a lump sum amount of $16,565.50. Please note: The Sebastian Inlet District (District), as part of their Inlet Management Plan, conducts semiannual beach profile surveys along the northern 5.6 miles of the County. The District continues to partner with the County and has agreed to provide their certified 2024 beach profile survey data to the County, resulting in a complete 22.4 mile countywide beach profile survey and a combined annual savings of approximately $30,000 to the County. FUNDING Funding for these tasks comes to a total lump sum fee of $63,592.00. Funding for the individual tasks are as follows:
