Read the Federal Highway Administration’s (FHWA) recently published white paper on Nature-Based Solutions for Coastal Highway Resilience. The white paper briefly describes the current state of practice regarding the use of natural and nature-based features to protect coastal roads from flooding. It provides an overview of available tools for design, implementation challenges, and knowledge gaps. Nature-based features mimic characteristics of natural features and processes but are created by human design and engineering. Examples include restoration of dunes, wetlands, maritime forests, beaches, and reefs. These features can protect coastal highways from the brunt of storm surges and waves. Some can adapt to sea level rise by accreting sediment or migrating inland. They can also provide benefits such as recreation opportunities, habitat needed for commercial fisheries, and a healthier environment.
This white paper is part of an FHWA project that also includes five pilot projects, regional peer exchanges, and an implementation guide. The project’s research and technical assistance will enable transportation agencies to use natural and nature-based features to improve the resilience of transportation systems.
