Surface waters, such as streams and wetlands, 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.
This low-intensity evaluation consists of an existing documents review (published soil, topographic, and aerial maps) coupled with an on site investigation to determine the approximate location of potential streams and wetlands. 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.
Stream and wetland 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.
When impacts to regulated waters or buffers can’t be avoided, then it's 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.
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 stream location or 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.
