Subject: Bridge No. 30287 – Anson County
Duncan Road (SR 1241) over Shaw Creek
Endangered Plant Commitments

Dear Ms. Fuemmeler:

The North Carolina Department of Transportation proposes to replace Bridge No. 30387
over Shaw Creek on Duncan Road (SR 1241) in Anson County. A temporary, on-site
detour is planned for this project.
A population of Schweinitz’s sunflower (Helianthus schweinitzii ), Principal EO 160,
occurs in this area. Based upon a survey by Alderman Environmental Services, Inc.
(enclosed), approximately 382 Schweinitz's sunflower stems associated with subEO 158
were documented on February 28, 2012. Most occurrences were located outside of the
project limits.
The rescue of approximately 20 Schweinitz’s sunflower stems is necessary due to the
removal and replacement of the bridge and construction of the on-site detour. (Since the
detour is temporary, newly disturbed habitat may facilitate expansion of the sunflower
population.) Stems around the existing bridge, along the existing road, and within the
planned on-site detour area will need to be rescued and relocated to a protected area
within the Pee Dee Wildlife Refuge. These sunflowers will be relocated after the
growing season ends and growth has died back and all work will be coordinated with the
United States Fish and Wildlife Service.
In addition, the following commitments are being made by the NCDOT to minimize
impacts to the remaining plants within the immediate project vicinity:
- The proposed culvert guardrail located on the north side of the project will be
reduced in length and will extend only 13.5 feet away from the culvert in any
direction.
- The roadside ditch on the north side of the project will remain “as is” and will not
be graded as originally proposed.

- The upper 12 inches of topsoil within the immediate project limits will be
stripped and stockpiled prior to the project beginning construction. The
stockpiled material will be used during final landscaping for the project with the
hopes that any Helianthus schweinitzii seed in the topsoil will have the
opportunity to germinate.
If you have any questions regarding this correspondence or the attached pre-construction
notification form, please feel free to contact me at 704-301-4881.
Sincerely,

Larry Thompson
Environmental Officer
10 th Highway Division

SCHWEINITZ’S SUNFLOWER SURVEY REPORT

PROJECT: Protected species survey report for Schweinitz’s sunflower (Helianthus
schweinitzii ) for the proposed Replacement of Bridge # 30 287 over Shaw Creek on Duncan Road
(SR 1 241 ) in Anson County. WBS: 17BP 10.R.31

REPORT BIOLOGISTS: John M. Alderman and Joseph D. Alderman

The North Carolina Department of Transportation proposes to replace bridge number 30 287 over
Shaw Creek on SR 1 241 in Anson County (Figure 1). Shaw Creek is located in the Pee Dee
River Basin.

Schweinitz's sunflower (Helianthus schweinitzii) was listed as endangered by the US Fish and
Wildlife Service (USFWS) on May 7, 1991 (USFWS 1991). Natureserve (2012) ranks
Schweinitz’s sunf lower as G3, a vulnerable species. Endemic to the Piedmont of the Carolinas,
this species has a range limited to 13 North Carolina counties (NCNHP 2012) (Anson, Cabarrus,
Davidson, Gaston, Mecklenburg, Montgomery, Randolph, Rowan, Richmond, Stokes, Surry,
Stanly, and Union) and 2 counties in South Carolina (Lancaster and York).

Schweinitz’s sunflower requires landscape disturbance, historically fire and grazing by bison and
elk. Due to fire suppression and the extirpation of bison and elk in the Piedmo nt, Schweinitz’s
sunflower is largely limited to roadsides and protected areas specifically managed for the
sunflower. Additional impacts to the species include herbicide application on roadsides,
roadside mowing during the growing season, and invasive pl ant competition.

Schweinitz’s sunflower is a member of the Asteraceae family and was discovered by Lewis
David von Schweinitz and described by Asa Gray and John Torrey. Typically, Schweinitz’s
sunflower will grow to a height of approximately 2 meters bet ween spring and winter, dying
back after the growing season, leaving only the tuber. Its leaves are opposite at the base of the
stem and alternate nearing the tip, pubescent, with a rough leathery feel. The stems are
pubescent with a purple coloration an d extend from the main stem at near ly a 45 degree angle.
Multiple yellow flowers are produced between August and the first frost.

Prior to conducting a Schweinitz’s sunflower survey, a review of the North Carolina Natural
Heritage Program (NCNHP) database was conducted to determine if there were any species
records within the proposed project study area. This review indicated that an occurrence of
Schweinitz’s sunflower exists at the bridge crossing (principal EO 160) with a subEO (059)
located le ss than 0.33 miles away along SR 1216 (Redfearn Road). Although conflicting
principal EO and subEO ranks exist within the NCNHP records for these 2 records, available
data suggest that the subEO located along SR 1216 is the most significant with an EO_ran k of B
associated with a 2007 survey. An EO rank of D is associated with the subject Duncan
Road/Shaw Creek element occurrence based upon a 2007 survey.

Biologists John M. Alderman and Joseph D. Alderman completed a Schweinitz’s sunflower
survey within t he project area ’s maintained/disturbed habitat, other nearby habitats, and along
SR 1216 (quick reconnaissance) on February 2 8 , 2012. Total time devoted to the survey was 10
person -hours. A follow -up survey associated with the project area was conducted on October 10,
2012. Total time devoted to this survey was 4 person -hours.

During the quick reconnaissance survey along SR 1216, 100 individual occurrences of
Schweinitz’s sunflower were documented (approximately 150 stems total with most found along
t he southeast side of the road).

During the February survey, 382 Schweinitz’s sunflower stems were documented within the
NCDOT Bridge 30287 project area and up and downcreek from the bridge along Shaw Creek,
and 379 stems were documented during the Octob er survey in the same general areas. Most of
the individual stems were documented downcreek from the bridge crossing within relatively
open, disturbed habitat near the creek (Figure 1 and Table 1 ).

LLC.

Proposed Bridge Replacement Conservation Measures

1. Due to planned demolition and construction activities, Schweinit z’s sunflower plants within
clusters D, E, G, H, and I will be relocated by USFWS personnel to appropriate habitat . Using
October data, plants associated with 77 stems will be relocated. USFWS personnel will
determine if these plants will be moved back to this project site following bridge replacement.
2. An on -site detour will be constructed between the existing bridge and the closest occurrence
o f Schweinitz’s sunflower downstream from the bridge (cluster C). The temporary creek
crossing will use a double 60” pipe culvert 40 feet long. This crossing will start 37’ from the
south edge of the existing bridge.
3. No use of herbicides will occur associated with the planned project.
4. On the date(s) that bridge demolition occurs, a USFWS biologist will be on site to relocate
any discovered Schweinitz’s sunflower plants or root stocks. This biologist will be given a 1
week notice of demolition start date.
5. Using orange construction plastic barrier fencing, road rights -of -way , including the temporary
road, will be fenced off from construction activities and personnel.
6. Riparian zone disturbance will be minimized and will be limited to the temporary crossing
location and to the existing bridge replacement area. Orange construction plastic barrier fencing
will be used to isolate construction activities and personnel from the riparian zone and
Schweinitz’s sunflower occupied habitats.
7. Stream stabilization will be limited to using a nominal quantity of rip -rap at the new crossing
site to protect the new structure.
8. If any of the adopted conservation measures are not followed, work will cease and USFWS
consultation will be reinitiated.

As requested by USFWS personnel, a biological conclusion associated with this project for
Schweinitz’s sunflower will be provided by the US Army Corps of Engineers.
