Orange County
Subject: On -Site Determination for Applicability to the Jordan Buffer Rules (15A NCAC
02B.0267)
Project Name: Mangum Homestead Mitigation Site
Parcel 1D Numbers: 9851671991, 9851778621, 9851763367
Address/ Location: 1449 Foggy Bottom Lane, Hillsborough, Orange County, NC
Stream(s) Evaluated: Unnamed Tributaries to New Hope Creek, Classified as WS -V; NSW
Determination Date: 7/19/2019
Dear Andrea,
Staff: DWR, Shelton Sullivan
On July 19, 2019, Shelton Sullivan of the Division of Water Resources (DWR) Central Office
conducted an on-site review of features located on the subject property at the request of
Wildlands Engineering Inc. The purpose of the review was to determine the applicability
to the Jordan Riparian Area Protection Rules (15A NCAC 02B .0267) and perform stream
determinations within the proposed project easement.
The enclosed site map indicates the features evaluated and this information is also
summarized in the table below. Streams that are "Subject" are shown on the most recently
published NRCS Soil Survey of Orange County and/or the most recent copy of the USGS
Topographic (at 1:24,000 scale) maps, have been located on the ground at the site, and
possess characteristics that qualify them to be at least intermittent streams. Features that
are "Not Subject" are not depicted on the required maps, not present on the property, or
have been determined to not be at least intermittent.
Please note that there may be other surface waters located on the property that
may be subject to the Jordan Riparian Area Protection Rules, considered
jurisdictional according to the US Army Corps of Engineers, and subject to the Clean
Water Act.
