Mangum Homestead Mitigation Site
The Mangum Homestead Mitigation Site (Site) is located in Orange County approximately three miles
northwest of the Town of Carrboro (Figure 1). The Site is being submitted for buffer mitigation credit
and nutrient offset credit in the Cape Fear River Basin HUC 03030002 in accordance with the
Consolidated Buffer Mitigation Rules (15A NCAC 02B .0295) and the Jordan Water Supply Nutrient
Strategy (15A NCAC 02B .0262).
The proposed buffer restoration site is approximately 19.7 acres of primarily agricultural fields located
on the Mangum Family Homestead. The project includes the restoration, enhancement, and
preservation of riparian buffers along four unnamed tributaries and one ephemeral channel: UT to New
Hope Creek, UT1, UT2, UT2A and E1 (Figure 2). While UT to New Hope Creek and UT1 have areas of
established forested vegetation, UT2, UT2A, and E1 are mowed regularly with no existing riparian
buffer. Historically, the site was used for cattle, but its current use is agricultural fields for hay
production. The family has one donkey on the property, but its access is currently restricted to UT2A.
Historical aerials from 1938 through 2016 are available to further document the Site's long history of
agricultural use.
UT to New Hope Creek flows east through the Site in an established riparian buffer. Approximately 150
feet upstream of the confluence to UTI, the stream emerges from the mature hardwood buffer. While
the right bank maintains a forested buffer, the left bank opens to agricultural fields. UT1 flows south;
buffered by a strip of mature trees extending out 20-50 feet. UT2 enters the project parcels from a
mature forest off the project parcels, flowing northwest into UT to New Hope Creek. UT2A begins at a
seep, flowing northeast into UT2. E1 enters the site through a small pipe below a pond, flowing north
into UT2 at an existing driveway. The Site is characterized by gently sloped valleys dominated by
agricultural fields.

Survey Map (Figure 5), Concept Map (Figure 6), and Riparian Buffer Zones (Figure 7) are also attached.
