Central Boca Raton Summary & Conclusions

• From February to March 2004, a gain of approximately 747,000 cubic yards of sand was measured along 1.5 miles of beach.
• The April 2004 project area mean high water shoreline was, on average, 116 feet seaward of the pre-beach nourishment shoreline of February 2004.
• In addition to the beach nourishment project, a 170-foot groin was constructed 1,600 feet north of the Boca Raton Inlet, and the weir in the north jetty of the Boca Raton Inlet was shifted 50 feet seaward. The groin was constructed to slow the southerly transport of material and increase the protection of buildings to the north, and the weir was shifted seaward to provide for a wider equilibrated beach north of the inlet.

• The goal of the 2006 renourishment project was to replace the beach sand that was lost due to beach erosion and the combined impacts of the 2004 and 2005 hurricane seasons.  Due to the active storm seasons, sand eroded from the 2004 Central Boca Raton Beach Nourishment Project area migrated to the adjacent beaches, and into the offshore ebb tidal shoal seaward of Boca Raton Inlet.
