Brevard South Reach Summary & Conclusions

• The total placed volume (R-118.3 to R-139) was 1,462,400 cy above -16 ft-NGVD, based upon the Segment I and II pre- to post-construction profile surveys.  Of this quantity, 602,900 cy were placed above MHW.
• Approximately one-year elapsed between completion of Segment I and construction of Segment II. During this one-year interlude in construction the filled Segment I shoreline (R-122.5 to R-139) exhibited an overall net loss of -55,000 cy above -16 ft-NGVD, of which -44,600 cy was above MHW.

• May 2005 Conditions Relative to Initial Post-Construction (May 2003) Conditions:
  • Along the entire South Reach project area (R-118.3 to R-139), there was a negligible net volume loss of -3,500 cy above Mean High Water (MHW), and a net volume loss of -104,600 cy above -16 ft NGVD.
  • On overall average (R-119 to R-139), the South Reach berm and mean high water shoreline (MHWL) are currently recovered to within a few feet of the May 2003 post-initial construction locations.   Currently, the berm and MHW shorelines are an average of about 4.7 feet and 3.1 feet landward of the May 2003 shoreline, respectively.

• May 2006 Conditions Relative to Post-Renourishment (May 2005) Conditions:
  • The entire South Reach project area (R-118.3 to R-139) experienced a net loss of approximately -123,000 cy above MHW and a net gain of about +284,900 cy below MHW, for an overall net volume gain of about +161,900 cy above 16 ft, NGVD.
  • On average, the berm and MHW shorelines within the project area (R-119 to R-139) experienced landward movement (recession) which averaged about 25.9 feet and 29.8 feet, respectively.
• May 2006 Conditions Relative to Initial Post-Construction (May 2003) Conditions:
  • Along the entire South Reach project area (R-118.3 to R-139), there was a net volume loss of -126,500 cy above Mean High Water (MHW), and a net volume gain of +57,300 cy above -16 ft-NGVD.  During this period, about 579,000 cy of sand renourishment was placed in Spring, 2005 (reported pay volume).
  • On overall average (R-119 to R-139), the South Reach berm and mean high water shoreline (MHWL) are currently 31 feet and 33 feet landward of the May 2003 post-initial construction locations, respectively.

• The May 2006 survey data obtained by USCOE was deemed not sufficiently reliable (EF), therefore, some of the tables and graphs do not include this data.  Conclusions and results from Olsen & Associates utilizing this May 2006 survey are included however.
