2016 Townwide Physical Monitoring Report, dated February 2017
Reach 6: (R-110+100 to R-116+500)
Over the most recent monitoring period, Reach 6 exhibited a net shoreline advance of 3.8 feet with gains and losses occurring throughout the reach. Reach 6 exhibited a net volumetric gain (above -26.2 feet NAVD) of 4,197 cubic yards. Losses are only observed between R-113 and R-115. Since 1990, Reach 6 has exhibited a net shoreline advance of 49.4 feet and volumetric gain of 456,328 cubic yards (above -26.5 feet NAVD).
In general, Reach 6 has remained stable with a long-term trend of shoreline advance and volumetric gains. Much of this behavior can be attributed to the downdrift effect of the Mid-Town nourishment projects which have provided a sediment source to both Reaches 5 and 6. The monitoring data suggests that the functional limit of this beneficial downdrift effect occurs within Reach 6, in the vicinity of the FOOT revetment (between R-111 and R-116). This trend will likely continue in the short to medium term due to the continued migration of sand from the 2015 Mid-Town Nourishment Project to the south.
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
Due to high longshore transport energies evident in this Reach, coupled with the large trough located between 70 and 350 feet from shore and the extensive hard bottom resources, direct placement of sand in this shoreline segment is not recommended.
Reach 6 Related Shore Protection Board Recommended Actions, November 2009
Following 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.
Analysis underway. Final report from consultant expected in January 2011.
Because of the limited amount of sand going into Reach 7 from Reach 6, the condition of the Reach 7 beaches is a SPB concern. With most of the Reach 6 shoreline consisting of near shore hardbottom resources, a beach nourishment project is not practical. A thought to be considered by the SPB is to cover the revetment with sand, or place dune sand east of the revetment where the opportunity presents itself. Creating a more natural beach and dune profile in Reach 6 may provide a volume of sand during storm events to assist the north end of Reach 7 with storm recovery.
