Captiva Beach Nourishment Program
60 Years of Success
The residents and businesses on Captiva have successfully managed Captiva's beach for 60 years, improving and solidifying our beach with each project.
The success of the program is evident by the lack of any significant structural damage due to tidal and wave forces during the 2004 and 2005 hurricane seasons, including a hit by Hurricane Charley.
Captiva Erosion Prevention District (CEPD) has developed a comprehensive plan to protect the island’s shoreline and to strengthen it.. The program includes support from Federal, State, County and local agencies in a project team forged by the CEPD leadership over many years.
COMING SOON! - 2020-2021
On March 5, 2019, the Captiva voters approved the bond of no more than $18 million, to be assessed at actual cost once the work is completed. The restoration is needed and estimated to cost $30 million. The funding will be provided by the Florida Department of Environmental Protection, Lee County, the Lee County Tourism Development Council, and Captiva property owners. CEPD is communicating with the US Army Corps of Engineers about funding possibilities on a federal level, too.
This project requires a fill volume of approximately 900,000 cubic yards (BY) along approximately 25,600 feet of Gulf shoreline between FDEP survey monuments R-84 and R-109. The island-wide project extends between Redfish Pass and Blind Pass and would result in an average constructed added beach width of approximately 90 feet.
Construction of the next island-wide major renourishment project is anticipated for the winter of 2020-2021 and is covered by existing permits. Bidding should occur in early summer 2020, to support competitive pricing. Fill placement will likely be accomplished using a hopper dredge. Beach fill placement will take approximately 4 months, with another 2 months for mobilization and demobilization.
Public access to the project area will be open except where restrictions are necessary in the immediately vicinity of construction activities. The project has a 15-year Joint Coastal Permit (JCP) permit from FDEP, which is valid until December 11, 2029. Likewise, the federal authorization is covered by a Department of Army (DA) Permit issued by the USACE in 2015, which is valid until December 9, 2030.
Captiva Island ended 2013 with a wider beach beckoning residents and visitors to find more time to enjoy this beautiful island in 2014. The beach renourishment project extended the beachfront significantly further seaward with beach fill placement of 783,369 cubic yards along Captiva's shoreline from Redfish Pass to Blind Pass. As part of the Project, existing dunes were rehabilitated and native dune vegetation consisting of 318,750 plants was installed along the Captiva shoreline. The restored beach provides a buffer from storms for island property and structures while enhancing wildlife habitat and the recreational value of the shoreline. Additionally, 80,823 cubic yards of sand were pumped onto northern Sanibel as part of an interlocal agreement. Coastal Planning & Engineering provided all engineering services for the Project Sponsor, the Captiva Erosion Prevention District (CEPD).
The CEPD awarded Great Lakes Dredge and Dock the $19.4 million construction contract in August following a competitive bid process. The Project commenced on Captiva Oct. 7, 2013 following the hatching of the last turtle nest. While the Captiva segment of the Project was estimated to be completed on Nov. 26, the final load of sand was placed on the island at 8am on December 16 following delays due to technical problems with the booster pump Jesse. Once work on Captiva was complete, the pipeline was moved to northern Sanibel and fill placement on that island was completed at 3:30pm, December 26. The contractor used two hopper dredges, the Padre Island and the Dodge Island to vacuum sand from a borrow area located approximately 8 miles offshore in the Gulf of Mexico. This sand source is outstanding in its compatibility quality with the existing sand along the shoreline. The sand was then transported to the booster pump Jesse. The submerged pipeline length from the booster pump to the discharge area was two miles. The CEPD requested and was granted a permit modification to extend the area of the pipeline corridors to enable contractors to have more flexibility.
Project funding was provided by the State of Florida, Department of Environmental Protection, the Lee County Board of County Commissioners, and Captiva Island property owners. Prior to the Project, Captiva voters overwhelmingly approved a referendum to borrow funds for the beach nourishment Project.
In September, 2005, a project to renourish Captiva Island and northern Sanibel began under U.S. Army Corps of Engineers supervision. This project included compensation for 2004 hurricane losses. A series of storms impacted the project area not only before the construction but also during construction. Captiva Island received 1,116,387 cubic yards along the 4.9 miles of shoreline between Redfish Pass (R 84) and Blind Pass (R 109). Northern Sanibel Island received 244,630 cubic yards (R 110.5 to R 116) and Bowman’s Beach received 90,914 cubic yards.
On February 2, 1996, the initial renourishment of the 1988 project began. Fill was placed between monument R 84 (Redfish Pass Groin) and monument R 109 (Blind Pass Terminal Groin). The total Captiva Project volume was approximately 821,000 cubic yards. An additional 239,000 cubic yards of sand were placed on northern Sanibel as part of an inter-local agreement.
The first island wide nourishment project began August 17, 1988 and was completed on April 22, 1989. The beaches of Captiva were restored with sand obtained from the Redfish Pass ebb shoal borrow area. The nourishment project placed approximately 1,596,000 cubic yards of fill along 4.7 miles of beach between monument R 85 and monument R 109. This project was a federally reimbursable Section 215 Project. The berm width varied from 20 feet at the north end of the island, where fill from the 1981 project still remained, to 100 feet at the south end of the island. As part of this project, dunes were constructed from monument R 96.5 to R 108.
Known as the South Seas Plantation Project, 655,000 cubic yards of sand were placed in a project area that extended from FDEP monument R 87 to monument R 93.4. The work was completed in October 1981.
The first Captiva Island Project was built in 1961 and consisted of placing 107,000 cubic yards of sand in conjunction with construction of 134 groins. Most of the groins that were constructed have either since been removed, buried or destroyed.
