Tidal Elevation Survey. A tidal elevation survey will be conducted to determine location of the High Tide Line (HTL) and Mean High Water (MHW) elevations to be delineated along the beach. Databases will be reviewed and calculated based on best available data (i.e., accessible NOAA and TCOON stations). The PSP’s environmental survey subconsultant will utilize either a sub-centimeter Trimble RTK or Geo 7X GPS. Locations of HTL and MHW will be included within the waters and wetlands delineation and habitat survey report and also within the submerged aquatic resources survey report.
