Building climate and coastal resilience in the OBX

Nags Head can't ignore the rising sea
Dare County, in North Carolina’s Outer Banks—known colloquially as "the OBX"—is a dynamic barrier island chain that juts out into the Atlantic Ocean. The Town of Nags Head, located in the northern portion of the Outer Banks, is a unique coastal community steeped in culture, history, and rich in natural resources. Residents are resilient: they enjoy the setting, and they've become accustomed to the winds, storms, and other coastal hazards that shape their environment.

More than 11 miles long, Nags Head boasts the longest oceanfront shoreline of any municipality in Dare County. The town comprises single-family homes and an equal amount of conservation/open space in Jockey’s Ridge State Park and Nags Head Woods. While the year-round population is under 3,000, the seasonal population swells to approximately 38,000 during the peak summer season.
Throughout its history, the town has been visionary in dealing with, and planning for, complex coastal issues. In 2015, Nags Head initiated a comprehensive planning effort with direction from the Nags Head Board of Commissioners to explore and develop policy for sea level rise in their planning efforts. Mayor Robert Edwards summed up the motivation for the town to act:
“We can’t ignore what is happening and what will continue to happen with sea level rise. It is imperative that as we plan for the future, we explore how to build, preserve infrastructure, and meet community needs in light of rising sea level.”

Community workshop
Concurrently, the Town of Nags Head partnered with North Carolina Sea Grant to work with community members to better understand the town’s vulnerabilities to coastal hazards, including sea level rise. Dr. Jessica Whitehead, North Carolina Sea Grant Community Hazards Adaptations Specialist, led a team to implement the Vulnerability Consequences and Adaptation Planning Scenario (VCAPS) tool in an open public planning process. VCAPS is intended to engage community members and seek their input on potential coastal hazards, such as sea level rise.
Approximately 60 people participated in a two-day community workshop. Starting with the VCAPS building blocks, participants communicated what they felt were hazards, potential consequences of the hazards, and potential public and private actions to adapt to or mitigate the issues identified.
As the complexity of responses increased, one community participant noted, “As sea level keeps coming up, it makes these other hazards worse faster. It has opened my eyes to look at how we integrate all of this. Regardless of cause, we need to have it mapped and integrated.”
Diagramming is just the beginning
Based on information and outcomes from the VCAPS process, the town established a Coastal Resiliency and Sea Level Rise Committee in 2016. This committee reviewed the VCAPS diagrams and worked to consolidate and prioritize over 160 possible adaptation actions suggested by the public into a report.
The adaptation actions related to sea level rise and other coastal hazards were broken into four main categories: ocean management, estuarine shoreline management, stormwater management, and water (ground/surface) management. These adaptation actions developed through community involvement formed the foundation for policy in the town’s comprehensive plan.
“Participating in the VCAPS diagramming is just the beginning for the town in planning for sea level rise. While there has been a great deal of work on other coastal hazards, this is the starting point for learning how sea level rise will impact the town and determining possible adaptation actions,” said Holly White, Principal Planner with the Town of Nags Head.
Adaptation to coastal hazards, including sea level rise, is an important step to becoming resilient. A resilient Nags Head means the town and its residents:
- Withstand, respond to, and recover from disruptions without long-term damage to the economy or environment
- Require less government funding to recover, rebuild, and redevelop its communities
- Sustain the natural systems that provide ecosystem services, or benefits, directly and/or indirectly to support human survival and a high quality of life.
Implementing resilience in the town's comprehensive plan
Through the use of the VCAPS process during the Comprehensive Planning efforts, the town is ensuring preservation of its culture, history, vast natural resources, and way of life. In addition to a section on coastal resiliency and sea level rise in the recently adopted comprehensive plan, the town is continuing to work with North Carolina Sea Grant and other partners to implement adaptive actions. One of the first actions the town will undertake, in coordination with the University of Georgia and Stetson University, is to map potential damage from storms and sea level rise to understand and visualize consequences and investigate legal and policy barriers to adaptation.
“We understand and have been planning for a range of coastal hazards that the town is vulnerable to over the past fifty years. The VCAPS process has helped the town gauge the community’s understanding of sea level rise and engage them in thinking through how we take action to adapt. Their perspective and support is extremely important as we plan for the provision of infrastructure and services over the next twenty years. We are committed to doing what is needed to protect our community, way of life, and the natural systems that help provide protection against these hazards,” said Cliff Ogburn, Nags Head Town Manager.
