This thesis works through the design process for a flood protection barrier falling within a special sub-category that the research team has defined: Sustainable Hybrid Bridge Barriers (SHBB). The design starts with what is known as a visor gate, which has some limited precedent around the world. But this project offers a unique new approach to that basic structure, which not only performs as a barrier in large storms, but also incorporates a pedestrian bridge, functions in a relatively more sustainable fashion, and has aesthetic appeal. The design process for each element of the barrier, including its unique ballast system, are worked through in the paper. Future work to be done to implement such a design in reality is also described systematically. The design on this iteration was unfortunately unsuccessful, but the groundwork has still been laid for next steps.
