A TRUE COPY CERTIFICATION ON LAST PAGE Ecoloaical Associates Inc — Scope of Work and Cost Proposal RYAN L. BUTLERCLERK State and Federal Authorizations. All sea turtle monitoring and related activities will be performed under FWC Marine Turtle Permit #261 issued by FWC to EAI Co - President, Niki Desjardin. All persons engaged in monitoring performed by EAI for the Sector 3 Beach and Dune Nourishment Project will be listed on the permit. All data will be subject to rigorous QA/QC protocols and stored in EAI's project - specific database. Monthly summary reports will be furnished to APTIM. These reports will tabulate the dates and times of monitoring, names of monitoring personnel, numbers of sea turtle emergences by species, and numbers of nests marked and evaluated for reproductive success, as applicable. Monthly reports will be submitted to APTIM on the last day of the month following delivery of services (e.g., March report due no later than April 30), or as otherwise mutually agreed upon. *Monthly summary reports on sea turtle nesting and predation will also be sent to the Archie Carr National Wildlife Refuge to assist management efforts. Task 4: Nest Marking and Monitoring (FDEP Specific Condition 15) A representative sample of nests in the Project and Reference Areas will be marked for determination of nest fate and reproductive success (not to exceed 600 nests total). Nests will be marked using a series of stakes and surveyor's tape. These nests will be monitored throughout their incubation period to determine nest fate (e.g., hatched, washed out, depredated, vandalized, etc.). After an appropriate incubation period, and in accordance with the FWC Handbook, nests will be excavated to determine reproductive success. Two measures of reproductive success will be calculated: hatching success (the percentage of eggs in the nest that hatch) and emerging success (the percentage of eggs in the nest that produce hatchlings which successfully escape from the nest). Task 5: Post -Construction Escarpment Surveys (FDEP Specific Condition 18) Beginning on March 1, 2025, scarp surveys will be conducted on a weekly basis within the Sector 3 Project Area through October 31, 2025. In accordance with FWC protocol, scarps are functionally defined as an abrupt change in beach slope (greater than 45°) at least 18 inches in height that persists for a distance of 100 feet or more. The location of both the northern and southern terminus of each scarp will be recorded by GPS and average scarp height assigned to one of three categories (0 to 2 feet, 2 to 4 feet, and 4 feet or higher). Additionally, the maximum height of each scarp will be measured. The location (relative to R -monuments), approximate length, height category, maximum height, and percentage of beach scarped will be presented in tabular and/or graphic format for reporting purposes. EAI will notify APTIM of any FWC/FDEP-defined persistent scarps within the Project Area that may interfere with sea turtle nesting. APTIM shall be responsible for notifying FDEP/FWC of the presence of those scarps and for coordinating any remediation measures, if required. Any services required of EAI during scarp consultation and leveling will be charged separately on a time and materials basis
