(SAW-2019-01867) (DWR Project No.20191577)
Baseline Monitoring Documentation
Buncombe County, North Carolina
Dear Mr. Moore,
The attached Year 1 Quarter 1 Documentation is submitted on behalf of Lee Thomason and
Biltmore Farms, L.L.C. in compliance with condition 8 of the DWR 401 Permit WQC004226
issued June 1, 2020. Project Ranger is also authorized under Section 404 and Section 10 in a permit
issued by USACE on July 10, 2020 for the construction of a bridge over the French Broad River.
The site is located at 1600 Brevard Road, in Asheville, NC (Figure 1). A qualitative assessment of
the banks upstream and downstream of the bridge location was performed by ClearWater
Environmental Consultants, Inc. on June 10, 2021.
Please do not hesitate to contact me at 828-698-9800 if you have any questions or comments.
Sincerely,
Jeff Golladay
Project Biologist

Biltmore Farms Project Ranger
Year 1 Quarter 1— Photographic Documentation — 06/10/2021
Project Ranger is authorized to begin construction of a bridge over the French Broad River in a Section
404 and Section 10 issued by USACE on July 10, 2020, and the Division of Water Resources Water
Quality Certification Issued June 1, 2020. The site is located at 1600 Brevard Road, in Asheville, NC
(Figure 1). The Year 1 Quarter 1 qualitative assessment of the banks upstream and downstream of the
bridge location was performed by ClearWater Environmental Consultants, Inc. on June 10, 2021, in
compliance with condition 8 of the DWR 401 Permit WQC004226 issued June 1, 2020. This qualitative
monitoring will be repeated quarterly following construction of the bridge, for one year, or two bankfull
events (whichever is longer), and then annually for three years. Clearing for the bridge began in early
February 2021.
The assessment included collecting eighteen (18) georeferenced photographs of both banks of the French
Broad River and noting any existing visible areas of bank erosion (Figures 1 - 2). The upstream extent of
the study reach began at Bent Creek River Park, approximately 600 LF upstream from the proposed bridge
location, while the downstream extent ended at an overhead electric (OHE) powerline crossing,
approximately 1200 LF downstream from the proposed bridge location. The photo points were
georeferenced with Trimble sub -meter GPS device and collected both on foot and by canoe. Three areas
of active erosion or bare vertical banks were identified during the baseline survey conducted on December
21, 2020 and were observed again during the June 10, 2021 survey. One new area of sediment aggradation
was identified during the June 10, 2021 survey.
Area 1 includes portions of bank erosion at Bent Creek Park on the left bank of the French Broad River.
This is visible in Photo Point 1. The erosion in Area 1 is likely due to the lack of a forested buffer and
heavy use of the banks by the general public to access the creek. No change was observed.
Area 2 includes a vertical bare bank on the right bank of the French Broad River visible in Photo Point
14. This bare bank is immediately downstream from a log debris jam, approximately 350 feet downstream
from the bridge location. No change was observed.
Area 3 includes vertical bare banks which are actively slumping and eroding, located on the right bank of
the French Broad River. The Area 3 erosion is visible from Photo Point 8 and Photo Point 16. This portion
of bank lacks a forested buffer and is located in a maintained OHE right-of-way (ROW). The location of
the photo points and three areas of existing bank erosion are indicated on the attached Overview Map
(Figure 2).
Area 4 includes a newly formed area of sediment aggradation along the right bank of the French Broad
River. This area is forming along the right bank of the river, approximately 75 feet downstream from the
rip -rap causeway pile near the bridge construction site (Figure 2). The sediment aggradation is visible in
Photo Point 18. The aggradation affect may be caused by an eddy current downstream of the temporary
bridge causeway. The upland work area at this location was surveyed and no instance of silt fencing failure
or sediment escape into the river was observed.
