Accuracy levels shall be in accordance with the BBCS Standards. Data points will be collected at a maximum interval of twenty-five (25) feet and at all grade breaks (exceeding one-foot) and material changes along the profile. In the event the FDEP monument is located more than three hundred (300) feet landward of the vegetation line, data points shall be extended to one hundred (100) foot intervals from two hundred (200) feet landward of the approximate vegetation line to the monument location. The reference monument shall be recorded as range 0.0 along the profile with positive ranges extending seaward of the monument and negative ranges extending landward of the monument. Digital Photography As required by FDEP BBCS Standards, during the course of field data collection, digital photographs shall be taken at approximate mid-beach along each profile line. Three (3) photographs shall be captured, one each shore-parallel north and south of the profile and one towards the monument location. An additional photograph of the monument or TBM shall be taken with sufficient clarity to read the monument stamping. Digital images shall be provided to the BBCS on CD or DVD media , in image (.Jpg) format at a minimum 640 x 480 resolution. Profile Data Collection - Offshore Offshore profile data shall be collected from a point that overlaps the seaward limits of onshore data seaward to a range prescribed by the Client. Difference in time between the offshore and onshore profile data collection shall not exceed seven (7) calendar days. Offshore profile d ata shall be collected using an automated hydrographic system comprised of a survey launch equipped with a marine grade sounder, differential global positioning system and computer-based navigation / data collection system. The sounder shall be calibrated via bar checks at the beginning and end of each survey day in accordance with U.S. Army Corps of Engineers Specifications. Vertical accuracy shall meet or exceed that published in the BBCS specifications. The offshore survey shall continue seaward, extending to a minimum of 3000 feet offshore (from the most landward offshore data point) or to –30 feet (NAVD 88), whichever is reached first. Bathymetric profile data shall be collected as close to high tide as practical and shall extend landward to a de pth that overlaps the onshore portion of the survey a minimum distance of one hundred (100) feet. Maximum wave height during the course of bathymetric data collection shall be three (3) feet. Prior to the start of the survey a tide staff will be establi shed in proximity to the project for recording water levels during the course of the data collection activities. The tide staff will be set relative to published control in the vicinity of the project. Alternatively, SDI may employ the use of RTK GPS, including “on-the-fly” methods for collecting vertical data. Data Processing and Final Deliverables Upon completion of field survey activities, data will be edited and reduced to the project datum and translated to an x,y,z, ASCII format for submittal to the Client. In addition, and in accordance with BBCS Standards, the following deliverables will be provided:  Survey report / monument control report certified by a Professional Surveyor and Mapper.  Copies of field books and data collection files, as applic able. (hardcopy and PDF format)  Description of all monuments and TBM’s used for the survey, including identification, stamping, coordinates, elevations and profile azimuths, in both hardcopy and digital formats (ASCII & Excel)  Final profile data in ASCII XYZ format & FDEP distance/depth format with associated headers  ASCII raw data file  Digital photographs in .jpg format with appropriate labeling  Plan / profile charts in digital AutoCAD .dwg format (as required)  Plan/profile charts in hardcopy format (24”x 36”), one (1) draft copy & two (2) final copies  QA / QC Report
