This article proposes a steady-state subsidence forecast model to estimate changes in surface elevations of the wetlands and evacuation routes across coastal Louisiana for the years 2015, 2025, 2050, and 2100. The results indicate spatially heterogeneous rates of subsidence that are forecasted to consume nearly half of the existing coastal margin wetlands by 2100. Furthermore, it indicates that, relative to the impact on evacuation routes, subsidence occurring between the 2015 and 2025 forecast years expanded at slower rates when compared to the latter half of the century. The methods employed and findings produced demonstrate forecasting capabilities that provide emergency managers and transportation engineers with resources applicable to evacuation modeling, hazard mitigation, environmental sustainability research, costal restoration efforts, and more
