Driving Nature-Based Solutions Forward: Living Shorelines Stabilize Critical Evacuation Route Along North Carolina Coastal Highway
Following a devastating hurricane season in 2018, the North Carolina Department of Transportation (NCDOT) partnered with SWCA to stabilize and restore a particularly vulnerable portion of highway using a living shoreline.
Modeling by NCDOT’s Hydraulics Unit showed that in the likely event of a future hurricane, a 830-foot section of shoreline along NC 24 in Swansboro, North Carolina, could become unstable and lead to the roadway becoming unsafe for residential evacuation. The roadway’s designation as critical infrastructure and a primary evacuation route led NCDOT to emphasize the need for increased resiliency measures.
In January 2015, the Federal Aviation Administration (FAA) released the Draft Environmental Impact Statement (EIS) — produced in close coordination with SWCA — for the proposed Angoon Airport in Alaska. The document’s use of plain language, easy-to-understand graphics, and a navigable structure has earned praise from EIS readers and reviewers.
Invasive species are one of the greatest threats to the environment, economy, health, and quality of life of people. Planning ahead, securing funds, and hiring experts to develop an invasive species management program can help DOTs cost-effectively mitigate this problem. Preventing the next invasive species can save states millions of dollars in control and mitigation costs.
Cultural & Historic Resources
The Mission San Gabriel was founded in what is today San Gabriel, CA, by Franciscan priests at the end of the 18th century. As the city has grown, however, the need for infrastructure came in conflict with the history of the site. SWCA has conducted extensive cultural resources surveys and evaluations, mitigation, and monitoring to meet the needs of the National Historic Preservation Act (NHPA) and various stakeholders.
Every once in a while, a project that started as a routine compliance effort takes an unanticipated turn. SWCA Tucson’s Sunset Road Cultural Resources Data Recovery Project did exactly that when a backhoe operator uncovered human footprints dating ca. 1000 B.C. The team went on to earn an award for their handling of the find.
