SUBJECT: Protected species survey report for the James spinymussel
(Pleurobema collina) for the proposed bridge replacement
project aver Pennon Creek on Badgett Sisters Parkway
Road (SR 1156); Caswell County, Division 7 Project.
ATTENTION: Jerry Parker
Division Environmental Supervisor
The following memorandum addresses the James spinymussel (Pleurobema
collina), a federally protected species listed by the US Fish and Wildlife Service for
Caswell County. The habitat requirements for the James spinymussel include creeks or
river areas with substrate of cobble and sand in reaches with slow to moderate current
(Bogan, 2002). Habitat for the James spinyrnussel does exist in Pennon Creek. However,
these areas are patchy due to the fact most of the stream. was dominated by boulders or
gravel. A survey for freshwater mussels was done with no freshwater mussels being found.
Surveys, Habitat and Methods
A mussel survey was conducted on May 17, 2007 by NCDOT biologists, Neil
Medlin and Jared Gray. Pennon Creek crossing at SR 1156 (Badgett Sisters Parkway
Road) contained riffles, runs and pool areas with normal substrate compactness. The
substrate above and below the bridge consists of boulders being dominant and gravel ~, ,
being subdominant. The substrate also consisted of sand, silt cobble and bedrock with s``.~'°
slow to medium current. The portion of the creek that was surveyed had a moderate ~=~ ~'~~f~~-.~.4
buffer. The stream banks had some erosion and undercut banks in some areas. The land ~? n~: ~ ~~''`~-
use was naturaUactive pasture. Pennon Creek was shallow with 90 percent of the stream ~,';~ ,~. ° `:~r'
less than 2 feet deep. Pennon Creek was 4.0 meter wide and the bank heights were 1.5 -~ ~~, r' M~.~!?.

mussels were found in 2.25 man-hours of survey time. 2aP9

BIOLOGICAL CONCLUSION: No Effect
Given the survey results, that no freshwater mussels were found in Pennon, it is
apparent that the James spinymussel does not occur in the project footprint. The North
Carolina Natural Heritage Program (NCNHP) does not list a known population up or
downstream in Pennon Creek, which flows into the South Country Line Creek
approximately 0.25 miles downstream of the proposed project. There are no known
occurrences in the South Country Line Creek immediately up or downstream of the
confluence's of these two streams. From the confluence of Pennon Creek and South
Country Line Creek, it is another 5.3 miles to where South Country Line Creek flows into
the Country Line Creek. The James spinymussel has never been found in Country Line
Creek. NCDOT believes the proposed bridge replacement project would not effect the
James spinymussel.
