Definition

In the coastal zone, managed retreatis the application of coastal zone management and mitigation tools designed to move existing and planned development out of the path of both short- and long-term coastal hazards (e.g., hurricanes/typhoons, nor’easters, tsunamis, El Niños, king tides, erosion, flooding, storm surges, sea-level rise). This management strategy is based on a philosophy of avoiding or moving out of harm’s way and is proactive in recognizing that the coastal zone dynamics should dictate the type of management employed.

Introduction

Hino et al. (2017) note two defining features of managed retreat: deliberate intervention to manage hazard risk and abandonment of land or relocation of assets. Identifying and mapping the impact zones of coastal hazards is the basis for establishing regulations that govern moving property and people away from migrating and/or storm-impacted shorelines. The mirror of this goal to protect property is that the shoreline is allowed to...
