Wetland/Stream Reconnaissance or Preliminary

A low-intensity evaluation that consists of an existing documents review (published soil and topographic maps) coupled with an on site investigation to determine the approximate location of potential wetlands and streams. A written report and sketch map are provided to the client. This level of investigation is not intended to be used for detailed subdivision planning.

· Lower cost

· Potential wetlands are usually an over-estimation of actual wetlands on site

· Low-intensity investigation typically used by potential buyers or to verify wetlands are not within project boundaries

Wetland/ Stream Delineation

Wetland and stream delineations may be needed as a site planning tool for development, to obtain permits to impact regulated waters or buffers, or to resolve violations.

A wetland delineation consists of marking the precise boundary between uplands and wetlands with consecutively numbered flags. The existence and extent of any streams that exist on the property will also be determined and flagged as needed.  A sketch of the delineation is forwarded to a surveyor who will survey locate the flags and produce a map depicting the site and regulatory boundaries .

We may also collect site data necessary to submit the delineation to the US Army Corps of Engineers for concurrence. A site visit with agency personnel is customary to verify the delineation.

· High-intensity investigation

· Typically requested when impacts to regulated waters or buffers are anticipated or as information that local regulatory agencies request for development permits.

More Information about wetlands can be found in our Articles Section.

Wetlands and streams provide several important ecological functions and are currently regulated under the authority of the Clean Water Act (CWA).  HO&A has years of experience identifying these waters and preparing permit applications.  All wetland determinations are conducted using the appropriate Regional Supplement of the 1987 US Army Corps of Engineers Wetland Delineation Manual. Stream determinations are made in accordance with the NC Division of Water Resources Methodology for Identification of Intermittent and Perennial Streams and their Origins

Permitting Assistance:

CWA Section 404 and 401; Riparian Buffers

When impacts to regulated waters or buffers can’t be avoided, then its necessary to secure the appropriate permits.  We assist clients through the application process by coordinating with the surveyor or engineer, filling out forms, consulting regulatory databases, and compiling maps and documents. After submitting the completed application, we coordinate with agency personnel to fulfill additional information requests.


Riparian buffers extend from the top of bank on each side of a regulated stream.

· Efficient preparation of applications and supplemental documents

· We are advocates for your project and work diligently to achieve your goals

· An established rapport with regulators

Violation Resolution

Sometimes impacts happen before the proper permits are in place.  If a violation has occurred, you may be faced with costly fines and restoration fees in addition to time delays on your project.  We work on your behalf to resolve the violation as quickly as possible by responding to the agency requests for action.  This usually includes delineating the original wetland boundary for your surveyor to locate, preparing a permit application for after-the-fact authorization, and/or developing a restoration plan detailing the steps needed to return the damaged area to a more natural state.
