Ecological Associates,Inc.—Scope of Work and Cost Proposal 3 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 Director of Operations, 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. Daily sea turtle monitoring will be charged at a daily rate. *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 150 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). Tasks 5a-5b: Post-Construction Escarpment Surveys(FDEP Specific Condition 18) A pre-season escarpment(scarp) survey will be conducted within the Sector 3 Phase 1 Project Area two weeks prior to sea turtle nesting season. The length, average height category, and approximate maximum height(as described below)will be recorded for all scarps that may impede turtles from reaching suitable nesting habitat. A summary report will be provided to APTIM so that actions may be taken to remove the scarps prior to nesting season,if necessary. The pre-season scarp survey will be charged only if the survey is necessary. Beginning on March 1,2022,scarp surveys will be conducted on a weekly basis within the Sector 3 Phase 1 Project Area through October 31, 2022. 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
