Preliminary Jurisdictional Determination
Madison Fish Habitat Restoration Project
Rockingham County, North Carolina

Prepared by:

Introduction
Kris Bass Engineering is contracted to provide engineering services related to habitat restoration and fish
passage structures on the Dan River in the vicinity of the Town of Madison, NC, the Lindsey Bridge Dam,
and its impoundment. The Lindsey Bridge Dam is a low-head structure on the Dan River located
approximately 3 ½ miles upstream of its confluence with the Mayo River in Rockingham County, NC. The
dam was constructed in 1972 and is in disrepair and at risk of failure, according to dive surveys
completed in late 2017. The 11-ft tall dam is a barrier to fish passage and a safety hazard to recreational
users of the Dan. The water intake for the Town of Madison is located directly upstream of the dam,
prohibiting complete removal. Instead, a series of weir passages, in addition to partial removal of the
dam, have been proposed to enable the movement of fish species upstream and to improve the safety
of the area. In addition, constructed riffles are proposed upstream of the dam to provide enhanced bed
habitat in deeper waters of the impoundment.
The project is divided into two phases: Phase 1 involves the construction of riffles within the
impoundment to facilitate upstream movement of the Roanoke logperch and other small fish species.
Phase 2 is the partial demolition/lowering of Lindsey Bridge Dam and construction of seven rock weirs to
allow fish passage over the remaining dam. The total project area is less than 7 acres, including portions
of the Dan River.
Wetland impacts were considered during site selection and planning of the Madison Fish Habitat
Restoration Project. Federal policies require projects to minimize or avoid impacts on wetlands. Though
much of the project area is within the Dan River, a water of the US, planned construction and impacted
areas will extend into adjacent areas within the Dan River floodplain. This report details the process of
wetland identification, the resources evaluated pertinent to a preliminary jurisdictional determination
and identifies the extent of wetlands within and adjacent to the project area.
Data Review
This preliminary jurisdictional determination (PJD) was completed through a desktop GIS analysis,
utilizing all available forms of data to determine the potential extent of existing wetlands within the site
vicinity. Through a PJD, all features that may be wetlands are assumed to be wetlands for jurisdictional
purposes. Future field delineation of wetland areas may reveal some portions assumed to be wetlands
based on NWI data do not exhibit appropriate soils, vegetation, or hydrology to be considered
jurisdictional wetlands or alternatively areas not assumed to be wetlands do exhibit wetland
characteristics. At the time these data become available, an amendment to the wetland impacts may be
requested along with the submission of wetland delineation data sheets.
At this time, GIS and other digital data were examined to identify potential wetland areas. Data
examined in analysis include:
• Aerial photographs from NC OneMap (2018, 2014, 2010)
• LiDAR data from NC Floodplain Mapping Program
• National Wetlands Inventory data from USFWS
• USGS topography data (1:24,000 scale, intersection of Ayersville, Belews Lake, Ellisboro and
Mayodan quadrangles)
• USGS National Hydrography Dataset (NHD) GIS layers
• USDA Web Soil Survey data
• FEMA FIRM map panel 7905
The USFWS National Wetlands Inventory (NWI) indicates the presence of wetlands in the vicinity of both
Phase 1 and Phase 2 of the project. The USGS topography quads also show wetlands, as they utilize NWI
data. Using surveyed elevation data within the project area, NWI data was digitally aligned with the top
of bank line where data was available. 20.6 ac of wetlands are present within the review area, and of
that area 0.1 ac of NWI wetlands is present within the project area. These areas are shown in Figure 4.
In addition to the wetlands, the Dan River is shown as a jurisdictional water feature. 15,919 linear feet of
the Dan River are present within the review area. No other streams are shown within the project area.
NHD and NHDPlus GIS layers were assessed to determine the presence of any streams in the project
area (besides the Dan River). The data did not indicate any streams, other than the Dan River, present
within the project area.
LiDAR elevation data indicates a meandering surface channel is present which may represent an
ephemeral, intermittent, or perennial stream in the project vicinity. Portions of this stream may be
considered jurisdictional. This stream is marked in Figure 6.
USDA Web Soil Survey data identifies most of the project area as the Dan River loam soil type, 0-2%
slopes, frequently flooded (DaA). This soil type is listed in the Rockingham County Hydric Soils list under
hydric criteria 2 and 4, and is considered hydric in depressions and floodplains. In addition, part of an
access path in Phase 1 crosses includes the Codorus loam soil type, 0-2% slopes, frequently flooded
(CsA), which is also hydric in Rockingham County under criteria 2 and 4 in depressions and floodplains.
Hydric soils are shown in Figure 3.
The project area is within zone AE in the FEMA-designated floodway and 100-year floodplain, as
indicated in FEMA FIRM map panel 7905 (Figure 5).
Aerial photographs taken in 2010, 2014 and 2018 and obtained from NC One Map were assessed, as
well as historic Google Earth imagery. Visible vegetation is not indicative of wetland conditions.

Conclusion
Wetlands and streams are delineated in Figure 7. This delineation has not been verified by the US Army
Corps of Engineers or the NC Department of Environmental Quality – Division of Water Resources.
Conclusions on the presence and location of wetlands and streams were drawn using publicly available
data. Due to site access limitations, a full field delineation was not feasible. Site visits were conducted on
the accessible portions of land, and conditions appeared concurrent with the conclusions drawn from
desktop analysis.

This digital Flood Insurance Rate Map (FIRM) was produced through a uniquecooperative partnership between the State of North Carolina and the FederalEmergency Management Agency (FEMA). The State of North Carolina hasimplemented a long term approach to floodplain management to decrease thecosts associated with flooding. This is demonstrated by the State's commitmentto map flood hazard areas at the local level. As a part of this effort, the State ofNorth Carolina has joined in a Cooperating Technical State agreement withFEMA to produce and maintain this digital FIRM.
