Cummins Cederberg assessed the existing shoreline and infrastructure of Brickell Key Island in downtown Miami in order to understand the effects of sea level rise on normal and extreme conditions (e.g. hurricanes and tidal flooding).
An inspection of existing coastal infrastructure was conducted to identify vulnerable areas. The entire island perimeter was assessed to address all areas. Analyses of sea level rise and extreme tide events were conducted to understand water level design conditions. The potential for increased storm impacts was also assessed. Recommendations for long term planning were provided along with mitigation options.
Construction documents and environmental permitting was conducted for the design of recommended repairs. The recommendations included maintenance repairs to the bulkhead surrounding the island, including stormwater outfalls, continuing cap extensions across identified gaps to limit wave overtopping The design focused on adapting existing infrastructure to provide a cost-effective solution.
