Summary: Living shorelines are an infrastructure technique that uses native vegetation alone or in combination with offshore structures to stabilize the shoreline while maintaining natural coastal processes. Living shorelines provide a natural alternative to ‘hard’ shoreline stabilization methods like stone revetments or bulkheads, and provide numerous benefits including erosion control, the reduction of nutrient pollution, essential fish habitat, and buffering of the shoreline from waves and storms. In deciding whether a living shoreline is an appropriate solution for reducing erosion at a particular site, a living shoreline suitability computer model can be used to provide recommended upland and shoreline best management practices. This project will customize an existing living shoreline suitability model developed by the Virginia Institute of Marine Science to work in Perdido Bay/Wolf Bay/Ono Island complex in coastal Alabama; Lake Pontchartrain, Louisiana; and Galveston Bay, Texas. In addition, the developers will create an interactive decision support tool for these areas as well as Tampa Bay, Florida, where model adaptation is already underway, to illustrate the principles of the basic model and allow users to interact with it. The application of this model and tool to other water bodies within the Gulf of Mexico will help promote living shoreline protection options to federal and state agencies, homeowners, marine contractors, natural resource managers, and city planners. A series of workshops conducted by the model developers will assure the model and tool reach decision makers.
