What is a riparian buffer?

A riparian buffer is a vegetated area bordering a body of water, such as a stream, lake or pond.

How do riparian buffers work?

The vegetated area closest to the body of water stabilizes the streambank and provides shade and habitat for aquatic life. The vegetation also acts like a filter and sponge to remove, transform, or store nutrients and other pollutants. The outer reaches of the vegetated buffer slow and spread out the flow of water over the land, trapping sediment and attached pollutants

How are riparian buffers beneficial?

Riparian buffers filter stormwater runoff before it enters the stream. The vegetation within the buffer absorbs excess nutrients and sediment, controls erosion, moderates water temperature and provides habitat for wildlife. They also provide flood control and protect property.

Can I use the online soil survey maps to determine if a stream is subject?  

The most recent published version of the NRCS soil survey maps is the acceptable version to be used for applicability to the riparian buffer rules.  Buffer Clarification Memo # 2007-0008 and the Interpretive Ruling on NRCS Soils Survey Map clarify this in more detail. 

What is diffuse flow?

Diffuse flow refers to overland water flow that is spread out over the landscape, rather than concentrated in a defined channel or pipe.    

Where are riparian buffer protection programs in place?

There are state riparian buffer protection programs in the Neuse River Basin, Tar-Pamlico River Basin, Catawba River Basin, Randleman Lake Watershed, Jordan Lake Watershed and Goose Creek Watershed. There are also local buffer protection programs across the state.

Are there other programs with buffer or setbacks on surface waters?

Yes, there are many different programs. Stormwater programs include: Phase I and Phase II NPDES, Session Law 2006-246, Water Supply Watershed, Coastal Stormwater, High Quality Waters, Outstanding Resource Waters, Universal Stormwater Management and Goose Creek Watershed. There are also programs regulated under the Non-discharge (2T) rules with setbacks, including sewer extensions, irrigation systems and recycle systems. The Division of Land Resources implements a buffer on Trout waters.

Where do the riparian buffer rules apply?

In the Neuse River Basin, Tar-Pamlico River Basin and the Goose Creek Watershed the buffer applies to: intermittent streams, perennial streams, lakes, ponds, estuaries and modified natural streams that are depicted on the most recent printed version of the soil survey map prepared by the Natural Resources Conservation Service OR the 1:24,000 scale quadrangle topographic map prepared by the U.S. Geologic Survey.

In the Randleman Lake Watershed the buffer applies to: same as above OR if other site specific evidence indicates to DWR the presence of waters not shown on either of the two maps.

In the Catawba River Basin the buffer applies to: the Catawba River mainstem below Lake James and along mainstem lakes from and including Lake James to the South Carolina border in the Catawba River Basin. (Catawba buffer rules also apply to the South Fork of the Catawba river up to the 569’ elevation of Lake Wylie). 

In the Jordan Lake Watershed the buffer applies to: intermittent streams, perennial streams, lakes, ponds and reservoirs that are depicted only on the following maps: the most recent printed version of the soil survey map prepared by the Natural Resources Conservation Service OR the 1:24,000 scale quadrangle topographic map prepared by the U.S. Geologic Survey OR a map approved by the Geographic Information Coordinating Council and by the N.C. Environmental Management Commission.

Are there provisions to allow existing uses to remain in the riparian buffer?

Yes. A use is considered “existing” if it was present within the riparian buffer prior to the effective date of that rule for DWR regulated activities (Neuse: July 22, 1997; Tar-Pamlico: January 1, 2000; Catawba: June 30, 2001; Randleman: April 1, 1999; Goose Creek: February 1, 2009; Jordan Lake: August 11, 2009 or the date of local government implementation for local government regulated activities). For more information about existing uses, please see the appropriate buffer rule(s).

What uses are allowed within the riparian buffer?

The riparian buffer must be undisturbed, regardless of property size or type of land use. Within each set of buffer rules*, there is a Table of Uses for specific activities:

  • Exempt uses are allowed in the riparian buffer without approval from the Division of Water Resources (DWR).
  • (Potentially) allowable uses may occur in the buffer after written authorization from DWR (some of these impacts may require mitigation for the impacts).
  • Prohibited uses are not allowed in the buffer unless a variance is granted from the N.C. Environmental Management Commission.
  • Activities not listed in the Table of Uses are prohibited.

What restoration is required if the riparian buffer is cleared without a buffer authorization?

The Dvision’s clarification memo #2008-016 outlines the requirements.

When do I need a buffer authorization?

A buffer authorization, or a “no practical alternatives” determination, is required for any use that is designated as “(potentially) allowable” or “(potentially) allowable with mitigation” within the applicable buffer rule (see above for definition of uses).

When do I need a variance?

A variance is required for any activity that is listed as “prohibited” in the Table of Uses or that is not listed in the Table of Uses (see above for definition of uses). Variances transfer with the property and, once approved by the DWR, the variance does not expire.  There are two types of variances*, major and minor.

Minor Variances are for impacts to Zone 2 of the buffer only. Approvals for minor variances may be granted by DWR or the delegated local program.

Major Variances are for impacts to Zone 1 or Zones 1 and 2 of the buffer. Approvals for major variances may only be granted by the N.C. Environmental Management Commission.

* The Catawba rules only allow one type of variance which may be granted by DWR staff.

* The Goose Creek rules only allow for one type of variance which can only be granted by the N.C. Environmental Management Commission.

How do I apply for a buffer authorization or variance?

The pre-construction notification (PCN) form is used to apply for buffer authorizations, which includes a “no practical alternatives” determination. For variance applications, click here.

Where do I send my buffer authorization or variance application?

Please send your completed application with all attachments to:
     NC DWR, 401 & Buffer Permitting Unit 
     1650 Mail Service Center
     Raleigh, NC 27669-1650.

Is there an application fee?

No, there is no application fee for buffer authorizations or variances.

How can I track the status of my application? Who do I contact if I have questions about riparian buffer rules?

For questions about the riparian buffer rules, contact your local Surface Water Protection Regional Office Staff or Jennifer Burdette in the Central Office at 919-807-6364.

For minor variances and buffer authorizations in the Neuse and Tar-Pamlico Basins in the coastal counties (except for Carteret, Duplin and Onslow counties), contact the Washington Regional Office. Questions regarding the riparian buffer rules in Carteret, Duplin and Onslow counties can be directed to the Wilmington Regional Office.

For minor variances and buffer authorizations in the Neuse and Tar-Pamlico Basins in the non-coastal counties contact the Raleigh Regional Office.

For all major variance applications in every riparian buffer basin contact Jennifer Burdette at 919-807-6364 or jennifer.burdette@ncdenr.gov.

How can I access the project files?

Please go our electronic document management system to view and print files for projects that include buffer impacts, stream determinations, mitigation and 401 certifications and 401 stormwater management plans. 

Is there an Express Review option?

The Central Office is no longer accepting Express applications. The Washington and Wilmington Regional offices are still accepting Express projects. For more information about express review in those two regions click here.

Are there any local governments delegated to implement the riparian buffer protection programs?

Yes. As of August 1, 2011, these local governments are delegated:

  • Neuse: Orange County, Pitt County, Town of Morrisville 
  • Tar-Pamlico: Pitt County
  • Catawba: McDowell County, Burke County
