Nature-Based Solutions for Coastal Highway Resilience: An Implementation Guide

Overview

This guide is designed to help transportation practitioners understand how and where nature-based and hybrid solutions can be used to improve the resilience of coastal roads and bridges. It summarizes the potential flood-reduction benefits, co-benefits, and site suitability assessments for these strategies. Considerations for engineering and ecological design, permitting, construction, and monitoring and maintenance are also provided. This implementation guide is part of the U.S. Department of Transportation’s focus on Nature-Based Resilience for Coastal Highways.
