2016 Townwide Physical Monitoring Report, dated February 2017

Reach 5: (R-102+300 to R-110+100)

Over the current monitoring period, Reach 5 has experienced a net average shoreline recession of 6.5 feet with both gains and losses occurring within the reach. The reach exhibited a net volumetric gain of 12,964 cubic yards with overall gains in the north and south of the reach with losses occurring in the central portion of the reach.

Long term, this area has experienced a net shoreline advance of 43.6 feet since 1990 and has gained approximately 561,270 cubic yards (above -26.2 feet NAVD) throughout the entire shoreline segment. Gains in shoreline position and volume are directly attributable to the movement of material into Reach 5 from the Mid-Town beach projects within Reaches 3 and 4. These net positive trends are likely to continue in the short term due to the renourishment of the Mid-Town project segment over this monitoring period. Lacking regular renourishment of the Mid-Town project to the north, this reach would likely revert to a net erosion/recession condition consistent with conditions present prior to the initiation of the beach nourishment program.

FDEP Strategic Beach Management Plan, June 2015 Update

Strategy:
Maintain the Town's restored projects through monitoring and nourishment using sand from offshore sources and upland sources; construct a feeder beach to reestablish littoral transport for Reach 2; and construct restoration projects in environmentally suited areas of Reach 5 and Reach 8. Comply with the Palm Beach Island Beach Management Agreement (BMA), 2013

Comprehensive Coastal Management Plan, 1998 Update

Proposed improvements include beach fill and a groin field at the south terminus of the reach.

Reach 5 Related Shore Protection Board Recommended Actions, November 2009

Groin AnalysisFollowing the Groin Assessment performed, a Town consultant is currently analyzing the functionality of the Town's groin system. A plan to prioritize rehabilitation will be developed for SPB consideration.

Status
Analysis underway. Final report from consultant expected in January 2011.

Dune Restoration

The SPB recognizes that Reach 5 has maintained a healthy beach due to the sand moving down from Reaches 3 and 4. The SPB reserves the recommendation to consider adding sand into the beach and dune system in Reach 5. Placement of sand in the form of dunes will create a line of defense for the beachfront owners to improve the storm protection to South Ocean Boulevard. This action will add more sand to naturally be added into the littoral drift during a storm event, eventually bringing sand into the Reach 6 area.
