Protecting Wetlands in the Face of Policy Shifts:
Wetlands are invaluable ecosystems, pivotal in supporting biodiversity, public health, flood protection, and the economy. However, urban development has historically degraded these ecosystems, and recent changes in federal and state policies pose a significant threat to North Carolina’s wetlands.
Carteret County, one of North Carolina’s coastal counties, is particularly susceptible. Coastal Carolina Riverwatch (CCRW) partnered with UNC-Chapel Hill students to assess the impact of these policy changes and propose solutions.
Research focused on Carteret County’s wetland degradation over the past 25 years, analyzing water quality indicators and examining the current policy landscape.
In response to this research, CCRW recommends:
- Improving DEQ wetland data collection and organization practices.
- Implementing county-level policies modeled after successful initiatives.
- Expanding County-level wetland protections beyond federal and NC mandates
Preserving wetlands is crucial, especially with recent policy shifts reducing wetland protections. The report serves as a resource for county-level officials, offering insights into best practices for maintaining wetland sustainability amid climate change and increasing coastal development.
Project Background: Federal and State Policy Changes
Recent federal and state policy changes, including the Sackett v. EPA ruling and reclassification of wetland definitions in North Carolina, have left over 2.5 million acres of NC’s wetlands vulnerable to development. The overturning of state-level protections adds urgency to the need for new legislation. With the threat of polluted waters and habitat destruction, timely action at the county level becomes imperative.
Importance of Wetlands: Economic, Biodiversity, Public Health, and Shoreline Erosion
Wetlands are intricate ecosystems vital to economic activities, biodiversity, public health, and shoreline protection. Recreational activities, tourism, and economic contributions are intricately linked to wetlands, making their degradation a threat to these sectors. Biodiversity, a cornerstone of wetland ecosystems, is at risk due to natural causes and human activities. Wetlands also contribute significantly to public health by impacting disease spread, nutrition, and providing medicinal resources. Moreover, they serve as natural buffers against shoreline erosion and flooding.
Problem Statement and Methodology
Recent legislative changes pose a threat to North Carolina’s wetlands, necessitating a comprehensive analysis. Our team conducted in-depth research on wetland coverage changes and water quality in Carteret County, along with an examination of wetland protection programs at various levels of government. The findings informed our policy recommendations to protect Carteret County’s wetlands from future degradation. |

A Review of Historical Wetland Degradation Trends:
The research focused on assessing wetland degradation in Carteret County over the past 25 years, employing data from dredge-and-fill permits, C-CAP Land Cover Data, and GIS mapping. The analysis of dredge-and-fill permits proved challenging due to data organization issues and lack of distinction between D&F and CAMA permits.
Consequently, the study shifted to C-CAP Land Cover Data, revealing minimal changes in land development and wetland prevalence, leading to the conclusion that notable wetland degradation in Carteret County is unlikely.
The GIS analysis using the NCLD supported these findings, indicating minimal changes in wetland and impervious surface prevalence from 2001 to 2019.
The study suggests that existing protections, including the Clean Water Act, may have contributed to the stability of wetlands in the region. However, potential risks arising from recent legislative changes highlight the need for continued monitoring. READ THE FULL REPORT HERE. |

A Review of Water Quality Indicators:
The study assessed five potential water quality proxies, including harmful algae blooms, swim advisories, shellfish closures, “Impaired” / CWA Section 303(d) waters, and economic impacts.
Despite employing data analysis software, significant limitations were identified for each proxy, preventing a reliable assessment of water quality changes over time in Carteret County.
Integrating water quality data with wetland degradation, multivariate regressions revealed a correlation between time and algae blooms with an increase in impaired water bodies. However, the connection to wetland degradation was found to be less definitive, and minimal correlation was observed between the indicators and the number of Dredge-and-Fill permits.

A Review of Federal and NC Policies:
The study delved into federal and North Carolina environmental policies, particularly examining alterations in the definitions of “waters of the United States” (WOTUS) and “State waters.”
The research focused on the impact of these changes on the legal safeguards for wetlands under the Clean Water Act (CWA). Notably, the opposition to the 2015 shift in the WOTUS definition led to a significant reduction in wetland protections in 2018.
The analysis highlighted four key court cases offering insights into diverse interpretations of WOTUS at the federal level. Additionally, the study explored stringent wetland protections in North Carolina at the state level, noting limitations imposed by recent legislative changes. READ THE FULL REPORT HERE.
A Review of Implementable County Policies:
The study investigated county-level ordinances and wetland protection initiatives in Carteret County, as well as in other coastal North Carolina and Maryland counties.
Notably, Carteret County was found to have a passive role in wetland protections, leaving these ecosystems vulnerable under local laws. The research suggests that learning from successful advocacy in local townships and effective wetland policies implemented elsewhere could offer valuable insights for Carteret County to enhance its own wetland protection measures.

Summary of Policy Recommendations:
Data Collection and Storage Improvements:
Overhaul data collection and organization practices for wetlands.
Lobby the state government, especially the NCDEQ, to update data collection and create a standardized digital database.
Allow county and local governments access to the database for recording and analyzing wetland data.
Mirror Other Coastal County Policies:
Implement a Watershed Master Plan (WMP) similar to Cecil County, focusing on community partnerships and infrastructure improvements.
Adopt ordinances resembling Anne Arundel County’s Natural Features Green Notices for early consideration of environmental features in the development process.
Expansion of Local Wetland Protections:
Recognize all wetlands as environmentally-important waterways through the authority granted by the Clean Water Act (CWA) and NC Coastal Resource Commission (CRC).
Utilize the 1980s WOTUS definition to determine basic wetlands with environmental significance.
Expand conservancy zoning, especially through Areas of Environmental Concern (AECs) and Natural and Cultural Resources Areas (NCRA).
Collaborate with Indigenous groups, particularly the Tuscarora, to protect wetlands associated with their cultural heritage.
These recommendations are aimed at improving the understanding and protection of wetlands in Carteret County, addressing data limitations, implementing effective policies, and expanding conservation efforts beyond federal and state mandates.

Using the Report for Advocacy and Action
|
On Monday, January 8th, the Beaufort Town Commissioners met to discuss and approve the Phase 3 expansion of BeauCoast. This development has caused concern for many Beaufort residents and water quality advocates.
Riley Lewis, Waterkeeper, and Ashlyn Clark, recent UNC graduate and partner in “The Future of Coastal Wetlands” project with CCRW, spoke during the public comment period about their concerns with the development. Unfortunately, there has been a change to the commission meeting agenda process. Public comments can only be made after agenda items are voted on – making this an unfair advantage for developers and silencing the voices of the community to be heard on record before votes by the commission. |

Regardless of the unanimous vote approving the final plat for development expansion, getting comments on the record was necessary to influence better-informed decisions. Riley Lewis spoke about her concerns with areas of development that would impact coastal wetlands and cause flooding. She also brought attention to the projected flood maps and addressed concerns about these new homes “being underwater” in the future. She also talked about her recent (day of the meeting) site visit that revealed problems with the project regarding potential DEQ Land Use violations, including down silt fences and standing water.
Ashlyn Clark spoke about the importance of coastal wetlands and how local governments can use policies outlined in the project that go above and beyond what the state and federal governments require. These policies can help protect citizens from flooding and water quality concerns. By adopting local policies outlined in the report, the town could be proactive and protect its citizens from water quality impacts, coastal flooding, and more. Federal and state policies are only meant to provide some essential protection from what is happening in the country or, in the case of NC, maybe Raleigh. Local governments on the coast need extra measures because our concerns differ significantly from those of most of the country and the state.
CCRW Advocacy Working Group members, including Dr. Jud Kenworthy, were in attendance. CCRW Business members, including Harriet Altman (Travel Right), spoke out about the concerns with holding public comments until after commissioners vote on agenda items.
Join us for the next Advocacy Working Group meeting – get on the list by emailing Waterkeeperand help us encourage local government officials to protect wetlands. Together, we protect the quality of water and quality of life for ALL in coastal NC. |
