Natural Resources Technical Report WBS BP13.R024, Madison County, N.C.
1.0 INTRODUCTION
The North Carolina Department of Transportation (NCDOT) proposes to Replace Bridge
560152 on SR 1318 (Big Laurel Rd.) over Spillcorn Creek (WBS BP13.R024) in Madison
County (Figures 1 and 2). The following Natural Resources Technical Report (NRTR) has
been prepared to assist in the preparation of the appropriate environmental documentation.
2.0 METHODOLOGY
All work was conducted in accordance with the NCDOT Environmental Coordination and
Permitting's Preparing Natural Resources Technical Reports Procedure and the latest
NRTR Template (September 2021). Field work was conducted on January 9, 2023. Water
resources identified in the study area have not been verified by the U.S. Army Corps of
Engineers (USACE) or the North Carolina Division of Water Resources (NCDWR). The
principal personnel contributing to the field work and document is provided in the
appendix.
3.0 TERRESTRIAL COMMUNITIES
Four terrestrial communities were identified in the study area. Figure 3 shows the location
and extent of these terrestrial communities. Terrestrial community data are presented in the
context of total coverage of each type within the study area (Table 1).

4.0 PROTECTED SPECIES
4.1 Endangered Species Act Protected Species
The United States Fish and Wildlife Service (USFWS) lists the following federally
protected species within the study area, under the Endangered Species Act (ESA) (Table
2). For each species, a discussion of the presence or absence of habitat is included below
along with the Biological Conclusion rendered based on survey results in the study area.

Tricolored bat
USFWS optimal survey window: May 15 — August 15

This information will be provided by the NCDOT Biological Surveys Group
(BSG). A review of NHP records, updated January 2023, indicates no known
occurrences within 1.0 mile of the study area.
Monarch butterfly
Biological Conclusion: Not Required
Habitat for the monarch butterfly is present in the study area in the roadside rights -
of -way and maintained lawn areas. However, the monarch butterfly is listed as a
Candidate species and is not currently afforded protection under Section 7 of the
ESA. A review of NHP records, updated January 2023, indicates no known
occurrences within 1.0 mile of the study area.

4.2 Bald and Golden Eagle Protection Act
The Bald and Golden Eagle Protection Act is enforced by the USFWS. Golden eagles do
not nest in North Carolina. Habitat for the bald eagle primarily consists of mature forests
in proximity to large bodies of open water for foraging. Large dominant trees are utilized
for nesting sites, typically within 1.0 mile of open water.
A desktop-GIS assessment of the project study area, as well as the area within a 1.0-mile
radius of the project limits, was performed on January 8, 2023, using 2022 color aerials.
No water bodies large enough or sufficiently open to be considered potential feeding
sources were identified. Since there was no foraging habitat within the review area, a
survey of the project study area and the area within 660 feet of the project limits was not
conducted. Additionally, a review of the NHP database, updated January 2022, revealed
no known occurrences of this species within 1.0 mile of the project study area. Due to the
lack of habitat, known occurrences, and minimal impact anticipated for this project, it has
been determined that this project will not affect this species.
5.0 WATER RESOURCES
Water resources in the study area are part of the French Broad River basin [U.S. Geological
Survey (USGS) Hydrologic Unit 06010105]. One stream was identified in the study area
(Table 3). The location of each stream is shown in Figure 4.

Spillcorn Creek has been designated as an Outstanding Resource Water (ORW) within the
study area. There are no designated Water Supply watersheds or High Quality Waters
(HQW) within the study area or within 1.0 mile downstream of the study area. The North
Carolina 2022 303(d) list of impaired waters does not identify any streams within the study
area as impaired waters.
6.0 REGULATORY CONSIDERATIONS
6.1 Clean Water Act Waters of the U.S.
One stream was identified in the study area (Table 4). The location of this stream is shown
on Figure 4. All streams in the study area have been designated as cold -water streams for
the purposes of stream mitigation.
