In September 2008, Hurricane Ike severely eroded the Gulf-facing pedestrian beach seaward of Beach Drive at the Village of Surfside and damaged the engineered rock revetment between the beach and Beach Drive, constructed under CEPRA Cycle 5 and completed in August 2008, weeks before landfall of Hurricane Ike.
In response, as part of an integrated emergency erosion response strategy to address the Ike-induced and ongoing critical erosion of the Gulf-facing shoreline adjacent to Beach Drive, the GLO initiated the Surfside shoreline stabilization project to repair Ike damage to the revetment and enhance the structure to better withstand future storm impacts as well as the Surfside emergency beach nourishment-dune restoration project to protect the toe and structural integrity of the revetment and create a wide useable beach.
Surfside Shoreline Stabilization (CEPRA Project #1471)
The rock revetment structure was originally designed and built to protect Beach Drive and public and private infrastrucuture and property against a two-year return period storm. Hurricane Ike, a 30-year return period storm, displaced much of the revetment armor stone yet prevented major damage to the majority of Beach Drive; the revetment and road suffered damage costing approximately $919,050 to repair. This project involved FEMA Public Assistance funds combined with CEPRA funds. Work to repair and enhance the revetment was undertaken during the winter (January through March) of 2011 and consisted of installing 2,443 tons of large stone blocks trucked in from an upland source, relocating the existing armor stone, and filling voids with grout to fortify the revetment.
Surfside Emergency Beach Nourishment Phases 1-2 (CEPRA Project #1511)
This two-phased project renourished the pedestrian beach adjacent to Beach Drive, which which was minimal to non-existent due not only to the impact of Hurricane Ike and other previous tropical storm events but also from the effect of ongoing erosion and lack of natural sediments in the shoreline system, all contributing to historical erosion and loss of elevation. This emergency renourishment was also necessary to facilitate the stabilization, repair and enhancement of the revetment which was impacted due to the effects of Hurricane Ike and subsequent high tides. The work involved trucking beach quality fill material from permitted upland borrow sources to the specified placement area and utilized FEMA Public Assistance funds relating to the mitigation of Hurricane Rita damages combined with CEPRA funds and 2008 CIAP state funds.
Phase 1 began in October 2010 and was completed by early March 2011, prior to the revetment repair and enhancement work. This phase consisted of placing 140,000 cubic yards of sand from a permitted site to widen the beach to a minimum of 75 feet along approximately 4,200 feet of shoreline. Phase 2 began in late January 2012 and was completed by early March 2012. This work consisted of transporting 40,000 cubic yards of beach-quality sand to the site, placing it to form coppice mounds which were tied into the existing revetment and also included a 45-ft wide berm to fill in eroded areas of the Phase 1 nourishment.
The reconstruction of coppice mounds will hopefully re-establish sea turtle nesting habitats and facilitate the formation of a natural barrier to prevent possible adverse impacts to nesting sea turtles from anthropogenic sources.
