Buffalo Creek Tributaries Mitigation Project
Buffalo Creek Tributaries Mitigation Project Site Description and Existing Conditions
The Buffalo Creek Tributaries Mitigation Project site is located in Johnston County between the
Community of Archer Lodge and the Town of Wendell. The project site is located in the NCDEQ
Sub -basin 03-04-06, in the Lower Buffalo Creek Priority Sub -watershed 030202011504, study area
for the Neuse 01 RWP and in the Targeted Local Watershed 03020201180050, all of the Neuse River
Basin. The project reaches are all unnamed tributaries to Buffalo Creek.
The project will involve restoration, enhancement, and preservation of stream, riparian buffer and
riparian wetland functions along unnamed tributaries to Buffalo Creek, a tributary to the Little River,
which is a tributary to the Neuse River. The project will involve the potential restoration, enhancement,
preservation, and permanent protection of unnamed headwater tributaries (Reaches MS -R1, MS -112, R3
(Lower), R3 (Upper), R4, R5, and 116), totaling approximately 4,838 linear feet of existing streams.
In addition, approximately 4.3 acres of degraded riparian wetlands will be returned to their natural
function, utilizing wetland restoration (rehabilitation) and enhancement approaches by implementing
Priority Level I Stream Restoration, limited removal of overburden soil above the hydric soils, and re -
vegetation. Combinations of different measures or "project clusters", will be implemented collectively,
along with the stream restoration, for a combined effect, to include riparian wetland restoration, riparian
buffer restoration, water quality improvement features, and agricultural best management practices
(BMPs).
This comprehensive approach utilizes a suite of stream mitigation practices, from Priority Level I
Restoration to Preservation, and appropriately addresses all intermittent and perennial stream reaches
at the project site, including restoring riparian buffers along all project stream reaches currently in
agriculture. The approach also includes restoring degraded riparian wetlands, and limiting the number of
stream crossings.
A majority of the existing stream reaches and riparian wetlands have been degraded significantly as a result
of historic and current agricultural and silvicultural practices, including man-made impoundments, and/or
channelization. Many of the project streams are unstable, with documented active headcut migration
with associated channel widening and bank erosion. Three of the project reaches, however, have
segments that have experienced less degradation, and are mostly stable and thus worthy of
enhancement. Additionally, one of the project reaches is relatively unimpacted, and as a result is stable
and thus worthy of preservation. Most of the project stream reaches and riparian wetlands have been
completely or partially degraded, even though they have adequate riparian buffers. Currently, the
project reaches act as significant sources of sediment to the project watershed, as well as the receiving
waters. The land use within the project area is comprised of mostly forested and mixed agricultural
(predominantly row crops), with a very small percentage of low density residential use.
A timeline of historical aerial photographs is attached to show the land use and land use changes in the
project watershed.
