EXECUTIVE SUMMARY

Review the 1st annual Hideaway Beach monitoring results, discuss resident’s erosion concerns and review the viability of using TDC funds to engineer, permit and install additional erosion control structures on Hideaway Beach. ______________________________________________________________________________ OBJECTIVE: Review the 1st annual Hideaway Beach monitoring results, discuss resident’s erosion concerns and review the viability of using TDC funds to engineer, permit and install additional erosion control structures on Hideaway Beach. CONSIDERATIONS: On April 13, 2004 the Board of County Commissioners authorized a one time use of TDC funds to stabilize Hideaway Beach with T-Groin structures. The City of Marco Island funded the sand placement, with Hideaway Beach residents repaying this amount through a seven year ad valorem tax. Hideaway Beach was re-nourished and T-Groins installed in FY 05/06. The 1st annual monitoring identified accelerated erosion between the beach segments that received T-Groins. The middle third of Hideaway Beach did not receive T-Groin Erosion Control structures because protection was anticipated from Coconut Island. Coconut Island has broken apart over the last 2 years and no longer provides erosion protection. The T-Groins that were installed performed as designed and prevented erosion on those sections of the beach that they protected. Preliminary analysis indicates that 3 to 5 T-Groin structures will be required to stabilize this section of the beach. Construction, permitting and engineering will cost between $1.2M to $1.8M. Residents have expressed concerns that erosion has progressed far enough that an active storm season could sever the road and isolate the 400 residents living on the north half of Hideaway Beach. Beach funding policy, approved by BCC 11-1-05, Para 5.b., states that an ineligible beach subject to high erosion, with recommendation of CAC and determination by the BCC as being in the public interest, may have erosion control structures installed with Category "A" funding.

COUNTY ATTORNEY FINDING: A finding by the County Attorney has not been made on this issue. ADVISORY COMMITTEE RECOMMENDATIONS: Determine if the CAC will support using TDC funds to construct additional erosion control structures on the portion of Hideaway beach that is currently unprotected by T-Groins.

FISCAL IMPACT: The Source of funds if approved by the Board of County Commissioners for the erosion control structures, their engineering and permitting will be Category “A” Tourist Development Tax fund. If sand re-nourishment is required by FDEP, the source of these funds will be from the City of Marco Island, with repayment anticipated from Hideaway Beach residents. GROWTH MANAGEMENT IMPACT: There is no impact to the Growth Management Plan related to this action. RECOMMENDATION: Obtain recommendation as to funding by the CAC. PREPARED BY: Gary McAlpin, Director
