BRIEF DESCRIPTION OF PROJECT AND RELEVANCE TO THIS CONTRACT (Include scope, size, and cost) <br /> <br />Summary <br /> <br />Marine resource mapping, engineering analysis and <br />seawall design, environmental permitting feasibility <br /> <br />Relevance <br /> <br />• The project demonstrates knowledge of coastal <br />and marine design conditions (i.e. hurricanes) <br />utilizing advanced numerical hydrodynamic and <br />wave models. <br />• The project demonstrates unique knowledge of <br />tidal flow conditions in Biscayne Bay. <br />• The project includes a variety of components <br />typical for Miami Beach. <br /> <br />Project Schedule/ Actual Schedule <br /> <br />On schedule. <br /> <br />Scope: Environmental Scientist, Engineer and Project Manager <br /> <br />Size: Approximately 1,500 feet of shoreline <br />Construction Cost: $400,000 (est.) <br />Description: <br />Crandon Marina is located along the northwest shoreline of Key Biscayne fronting Biscayne. <br />Severe sedimentation occurs in the northwestern portion of the marina. Cummins Cederberg <br />was selected to determine the source and cause of the sedimentation as well as provide <br />a solution. The Project area is exposed to both high tidal currents and wind generated <br />waves in Biscayne Bay. Due to the large tidal prism in Biscayne Bay, and limited flow <br />pathways in north Biscayne Bay, high current speeds are experienced during ebb and flood <br />tide in Bear Cut. Field investigations including surveying, marine resource mapping, <br />sediment sampling, as well as tide and current measurements were performed. A wave <br />analysis was subsequently conducted to understand wave characteristics during normal <br />conditions for the subsequent sediment transport assessment, and extreme wave conditions <br />for the design of coastal structures. A detailed numerical hydrodynamic model was <br />developed to simulate the tidal flow within Biscayne Bay and specifically the tidal flow <br />patterns at the Project site. Based on the results of the wave and hydrodynamic analyses, the <br />sediment transport at the site was assessed to understand the governing mechanism. <br />Concepts to eliminate or reduce sedimentation were developed and compared relative to the <br />current practice of dredging. The comparison included short and long-term costs, along with <br />environmental and engineering constraints. Cummins Cederberg was subsequently winded to <br />implement shoreline stabilization measures. <br /> <br /> <br />25.
