Jupiter / Carlin Summary & Conclusions

• Nourishment activities involved movement of sediment within the active profile rather than reintroduction of previously lost material.
• The March 1996 storm significantly impacted the area and induced widespread cross-shore movement of sediment beyond the limits of the profile surveys.
• This storm was the primary cause of the projects poorer than expected performance during the first year following construction.
• The borrow site filled rapidly due in large part to the cross-shore movement of material associated with the storm and longshore bypassing.
• The tidal channel reoriented southward following the deep water associated with the borrow area.

• In the first 12-months following project construction, the project area shows that approximately 537,400 cy or 86 percent of the renourishment project volume remained in the project area (above -22 ft NGVD).
• No additional hardbottom was covered due to the renourishment project.
• The average increase in berm width in the project area at the time of the 12-month post-construction survey was approximately 110 feet.
• The ebb shoal gained approximately 65,000 cy between December 2002 and December 2003.
• Moderate project spreading was observed downdrift of the project area.
