PRE/POST CONSTRUCTION SURVEYS & 3D LASER SCAN SURVEYS

Arc Surveying and Mapping, Inc. (Arc) was issued a contract to perform a pre-construction survey of the north jetty located at the Ponce de Leon Inlet, Florida.

The survey was performed during the 1st thru 3rd days of December 2020.

Utilizing a combination of data acquisition procedures including multibeam sonar, 3D Laser Scanning, and Real Time Kinematic (RTK) GPS. The procedures utilized resulted in high resolution spatial data, and provide an accurate surface model of the current condition of the North Jetty between surveys.

The surveys were performed utilizing previously established horizontal and vertical control located within United States Coast Guard Station Ponce Inlet.

The survey was performed to ACOE standards and compared to the ACOE survey data provided.

Minor bottom elevation variances between the provided contract survey data and the 2020 survey data were noted during quality control procedures and are attributed to the time lapse between surveys.
