South Naples Erosion Control Project (2000-2010) 

H&M was retained by a group of beachfront property owners north of Gordon Pass to evaluate their on-going erosion problem and design and permit an erosion control project. Erosion had been progressively extending north along the seawalled properties north of the inlet which is a Federal Navigation Project maintained by the Corps of Engineers since 1960. 


The purpose of the design was to reestablish a sustainable beach seaward of the seawalls with minimal maintenance. Working with individual property owners and the City of Naples, H&M designed and permitted the South Naples Erosion Control Project involving the construction of two low profile T-groins and two wooden permeable groins.  The project included the placement of approximately 6,000 cy of sand from an inland source for initial adjustments downdrift.  H&M was selected by the City of Naples to conduct construction management and monitoring for 5 years following construction. 


Design and permitting were paid for by the property owners while construction phase services were paid by the Tourist Development Tax Fund. Project coordination with City Consultant resulted in design being included in their Inlet management Study and ultimately eligible for TDC funds.

Subsequently H&M worked with individual property owners and completed maintenance of the structures 11 years post construction. The project performed very well and allowed for the reestablishment of native dune vegetation and sea turtle habitat in front of a seawall which lacked a beach prior to construction of the project
