Scope: <br />• Environmental permitting <br />• Engineering design <br />• Construction documents <br />• Cost estimates <br />• Bidding assistance <br />• Construction <br />administration <br />Cummins Cederberg was retained to conduct an erosion study, prepare <br />a beach design involving coastal structures to provide long term stability, <br />as well as conduct a benthic survey to quantity potential impacts to the <br />nearshore seagrass habitat. As part of the erosion study, a detailed <br />statistical analysis of offshore wave data was conducted along with a <br />wave propagations study, and an environmental feasibility study. Sediment <br />transport and potential erosion are typically governed by the wave <br />conditions. <br />Utilizing the advanced MIKE21 wave model, the wave transformation from <br />offshore to nearshore was analyzed. The detailed wave modelling allowed <br />for detailed review and comparison of the wave climate along the beach as <br />well as assessing sediment transport rates. <br />Based on the results of the wave modeling and sediment transport <br />assessment the underlying coastal processes of the erosion trends <br />were documented and utilized in the beach and coastal structure design <br />process. The area triggering the beach erosion was identified and solutions <br />for stabilizing this area, while still providing sandy beach access were <br />developed. <br />Understanding the underlying coastal processes allowed for an efficient <br />design that works with the natural processes, thus reducing long term <br />maintenance typically associated with projects working against nature. <br />Coco Plum Beach Restoration <br />Marathon, Florida <br />49RFQ No. 22-06-01
