the shoreline orientation change. At Government Cut entrance, the north jetty has been sand
tightened, which has eliminated the loss of fill material into Government Cut, and has stabilized the
beach width at this southern terminus of the project.
Panama City, FL. The Panama City beach fill was completed in 1999. Panama City is located on
the Gulf Coast of the Florida panhandle (Figure 19). The fill covered 28 km (17.5 miles) from
Phillips Inlet on the west to Panama City Harbor Entrance (St. Andrews Inlet) on the east.
Monitoring of shoreline change and volume of fill remaining was achieved through a series of beach
profiles located at the Florida Department of Environmental Protection (DEP) monuments R-1 to
R-91. Five hot spots were found at the west end of the project at R-4 and at R-10 to R-12 in
Hollywood Beach, R-19 to R-25 in Sunnyside Beach, around R-60 to R-65 in Panama City, and at
the east end between R-84 to R-91 near St. Andrews Inlet (from Coastal Planning and Engineering
2002).
No definitive cause was given for these hot spots, but the borrow areas were close to the beach in
several areas along this project and may have resulted in fill placed on the beach moving back to the
borrow trough areas. A general correlation exists between the locations of the borrow areas and the
hot spots. Wave refraction over these borrow holes, as well as other irregular bathymetry, may have
caused wave focusing at the hot spots, but no studies have confirmed this as yet. Both terminal ends
also measured losses.
