Task 2 Nearshore Turtle Abundance Monitoring <br /> Surveys of sea turtle abundance will be conducted by In-Water Research Group (IRG) along a <br /> series of 3-kilometer alongshore transects previously established by Indian River County. There <br /> are 3 transects , 300 , 600 and 1 , 200 feet offshore , in the project site transects extend from R- 10 to <br /> R-20 , and the three alongshore transects in the control site extend from R-62 to R-72 . Study sites <br /> and survey methodology will be in accordance with the issued project permits . <br /> Data will be tabulated and transmitted to ATM and Indian River County (IRC) at the conclusion of <br /> each survey effort — Spring 2009 (April-June) and Fall 2009 (August-September) . IRG will provide <br /> ATM with an annual summary report including a statistical analysis of sea turtle abundances <br /> between seasons, sites , and distances offshore. For seasonal comparisons and analyses , project <br /> site and control site will be pooled . Analyses of these data will include the dataset collected itn the <br /> 2007 during project construction . <br /> Task 3 Aerial Photography <br /> This task allows for the collection , rectification and geo-referencing of orthogonal aerial <br /> photography from R- 1 through R-22 per the DEP-approved Physical Monitoring Plan (February 2, <br /> 2007) . Two reconnaissance flights are included as an effort to capture clear, high water visibility <br /> conditions . <br /> ATM will provide the County with a set of aerial photographs and digital copies (with world files) of <br /> the aerials in TIF and JPG format. <br /> Task 4 Borrow Area Hydrographic Survey <br /> ATM will perform bathymetric surveys of the offshore borrow sites, which are identified as the <br /> Sectors 1 & 2 Primary Borrow Area (also referred to as the Sector 7 Borrow Site) and the Sectors <br /> 1 & 2 Secondary Borrow Area (formerly known as the Sectors 1 & 2 Borrow Site) . The <br /> bathymetric surveys will be conducted in accordance with the DEP-approved Physical Monitoring <br /> Plan . To be consistent with prior surveys , trackline line spacing will be 400 feet for the Primary <br /> Borrow Area and 500 feet for the Secondary Borrow Area . Included in this task is one weather <br /> day should inclement weather occur during the survey necessitating a re- mobilization to compete <br /> the survey. The Sebastian Inlet District will be conducting a bathymetric survey of the Sebastian <br /> Inlet Sand Trap , and has agreed with the County to share the data with ATM . The Sebastian Inlet <br /> Sand Trap survey dataset will be required to complete the physical monitoring report . <br /> ATM will provide the County with an xyz data file and drawings ( 11x17 format) showing the survey <br /> data and bathymetric contours. <br /> Task 5 Beach Profile Survey <br /> Morgan & Eklund will perform the beach profile survey data collection and data reduction . Beach <br /> profile will include R- 1 through R-22 . All data collected will be accordance with the DEP-approved <br /> Physical Monitoring Plan . ATM will provide review of submittals and project coordination as <br /> necessary, provide the County with beach profile data in ASCII file format , CAD drawings , and <br /> drawings ( 11x17 format) signed by the surveyor. <br /> Task 6 Physical Monitoring Report (2-Year Post-Construction ) <br /> ATM will analyze the project data and prepare a physical monitoring report per the DEP-approved <br /> Physical Monitoring Plan . The report will include reporting of the pre-and post-construction <br /> surveys of the beach profiles and borrow site . ATM will analyze the data for placed sand , <br />
