Multiple Lines of Defense
Multiple Lines of Defense - A multiple-lines-of-defense strategy has been utilized in the formulation of the Coastal Texas Study. Employing three primary strategies – avoid, minimize and mitigate – coastal communities should consider a system of comprehensive, resilient and sustainable coastal storm risk management solutions. The system should include a combination of measures (structural, natural and nature-based features, and non-structural) to form resilient, redundant, robust and adaptable strategies that promote life safety based on local site conditions and societal values. To achieve a multiple lines of defense approach, the Coastal Texas Study evaluates the following coastal problems: • Economic damage from coastal storm surge • Inland shoreline erosion • Gulf shoreline erosion • Loss of threatened and endangered critical habitats • Disrupted hydrology
