Coastal Engineering Consultants (CEC) has served on an integrated consulting team providing comprehensive services for beach restoration and inlet management to Charlotte County since 2001. The services have included:
- evaluating site conditions;
- evaluating economical and technical feasibility;
- coastal processes; modeling storm damage reduction benefits;
- designing beach fill templates;
- designing and analyzing potential adverse effects of utilizing borrow areas including enhancing safe navigation and providing improved hydrodynamics for circulation within the bay system;
- documenting construction access and staging;
- preparing detailed plans and specs; evaluating dredge equipment, capacity, and production rates; preparing opinion of probable construction costs;
- assisting with permitting; providing state/federal funding coordination including FEMA Post-Storm Recovery Funds; developing mitigation and monitoring plans; and
- conducting construction management and inspection services.
To date, the initial restoration (2003) and two renourishment events (2006, 2011) have been completed. State and federal cost sharing have provided approximately 45% of the total funds.
Currently, the County has embarked on their next 10-year management plan and CEC is serving as the lead firm to conduct the consulting services. Two new components are included in the next management plan. First, a regional sand source search has been completed to locate and define beach compatible sand bodies to address the sand needs of the County’s program for the next decade. Second, a detailed numerical model study has evaluated coastal structures to reduce end losses and improve project performance by stabilizing the erosional shorelines adjacent to Stump Pass. Hydrodynamic and morphologic change modeling has been performed on the no action, continued maintenance dredging / beach renourishment, and beach renourishment complemented with various structures alternatives to compare and contrast project performance and develop design criteria for the design and permitting phases.
