(http://www.dep.state.fl.us/beaches/publications/pdf/standard.pdf) Data collected for the monitoring of the project shall include beach profile surveys and inlet area surveys. These data will be collected by Maser Consulting for the topographic & bathymetric survey information. Prior to the start of the survey a reconnaissance of FDEP second order monuments is required to confirm that survey control is in place and undisturbed using Real Time Kinematic Global Positioning System (RTK GPS). In order to achieve required accuracy, the survey shall be controlled using FDEP 2nd order monuments. All accessible 2nd and 3rd order FDEP control monuments in the project area shall be located using RTK GPS. Topographic and Hydrographic profile surveys will be collected. All data seaward of the dune shall be collected using RTK GPS technology. Upland areas inaccessible to RTK GPS shall be collected using robotic total station techniques. Upland topography shall extend approximately 150 feet landward of the vegetation line or until an obstacle is encountered. An ACSM Certified Hydrographer shall oversee all hydrographic surveys for nearshore, offshore and inlet surveys. Hydrographic portions of the profile line shall be collected from a survey vessel equipped with RTK GPS technology and a dynamic motion sensor to provided instantaneous tide and motion corrections. Manual tide readings will be taken while conducting the onshore portion of the profiles to verify onboard tide readings. Standard hydrographic procedures shall be followed including all necessary quality control checks. Horizontal and vertical positioning checks will be conducted at the beginning and end of each day using second order FDEP monuments located in the project area. The fathometer will be calibrated via bar- checks and a sound velocity probe at the beginning and end of each day. The DIGIBAR PRO sound velocity meter or equivalent which provides a fast additional calibration for sound velocity as compared to the traditional bar check shall be used. More specifically, bar checks will be performed from a depth of five feet to a maximum depth of twenty-five feet. Analog data showing the results of the bar check calibration will be displayed on the fathometer charts at five foot increments during descent and ascent of the bar. LOR Page 13 of 52
