General Project Narrative: The Hereford Rd project proposes to excavate a portion of the road,remove the existing pipes,stabilize the excavated area and relocate utilities. The pipes have failed resulting
(Description of Minimization of Water in significant settlement of Hereford Road in the vicinity of the pipes. Attempts have been made to evaluate and measure the pipes but access due to the significant
Quality Impacts) failure/settlement has hindered this effort. Documentation has been found reporting the existing pipes as 2 @ 84"CMP with concrete headwalls. The inlet concrete headwall
can be observed. Failure of the pipes and settlement of the road was first observed around the time of Hurricane Florence in 2018. Due to the severity of the damage and the
impending loss of the roadway embankment into Falls Lake,the road has been closed and it is proposed to remove the pipes,open up the immediate area and stabilize the
banks with rip rap to the top of the excavation. This effort will also require the relocation of utilities. Due to the environmental sensitivity issues,safey issues,site constraints
and costs it was determined to remove the pipes and stabilize at this time. Herford Road is a causeway facility across Falls Lake,allowing for minimal opportunity to provide
treatment for surface stormwater runoff other than filtration by grassed shoulders. A significant portion of the existing causeway side slopes are already stabiliized with rip rap.
The existing grassed shoulders are stable as well. Grassed shoulders will be maintained outside of this excavated area and continue to provide filtration for road runoff.
Turbidity curtains are proposed in the lake during excavation operations for sediment control. There are buffer,lake and wetland impacts

Subject: Updated Bald Eagle, Michaux's sumac, and Smooth coneflower Surveys for
Hereford Road: Former 17BP.5.R.142 Pipe to Bridge on SR 1800 (Hereford
Rd) in Durham County; WBS: 51215.01Z.
Mr. Murray,
Please accept this memo regarding the updated surveys for bald eagle, Michaux's sumac, and
smooth coneflower for the above referenced project location.
Bald eagle: IPaC does NOT identify potential for this species at the project location. Habitat
for bald eagle primarily consists of mature forest 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. The project study area is immediately adjacent to a portion of Falls Lake,
however, a review of NCNHP records, October 2021, revealed no known occurrences of this
species within 1.0 mile of the study area. No bald eagles or nest trees were observed in the
study area or within 660 feet of the study area during a visual survey conducted on October
20, 2021. Due to the lack of the species or nest trees observed during the visual survey and no
known occurrences within 1.0 mile of the study area a biological opinion of No Effect is
rendered for this species.
Michaux's sumac: IPaC identifies potential for this species at the project location. Limited
habitat for Michaux's sumac is located within the project limits within the portion of the
study area particularly along the woods edge and within the maintained power easement. A
plant by plant survey of the project study area was conducted on October 20, 2021. No
specimens were found during the survey, therefore, a biological conclusion of No Effect is
rendered for this species.
Smooth coneflower: IPaC identifies potential for this species at the project location. Limited
habitat for Smooth coneflower is located within the project limits within the portion of the
study area particularly along the woods edge and within the maintained power easement. A
plant by plant survey of the project study area was conducted on October 20, 2021. No
specimens were found during the survey, therefore, a biological conclusion of No Effect is
rendered for this species.

This email has been received from outside of DOI -Use caution before clicking on links,opening attachments,or
responding.
Gary and Travis,
The Department has been monitoring the stability of 2 @ 7 ft corrugated metal pipes under the roadway fill at this
location for almost 18 months now. The pipes have failed resulting in washing out of the fill adjacent to the pipe
structures. Attached photographs depict the current situation at the site.
The pipes convey Rocky Branch, which is actually an impounded finger of Falls Lake. See attached site map and vicinity
map. At this time, the Department is preparing an environmental document and eventually a permit application to
USACE and NCDEQ DWR only to remove the failed pipe structures and adjacent fill. The stream channel (bed/bank)
would be shaped up based on the hydraulic design to be an open channel with 2:1 slopes. See below draft sketch:

CUkn It RIP RAT CLASS tf RIP RAP
Funds have been approved to complete this work as Phase I. The Department is also having preliminary discussions on
options for Phase II on what to do at the site after the pipes/fill are removed including: 1) permanent road closure, 2)
installation of a replacement culvert(very unlikely) or 3) installation of a single span bridge. All these are up in the air.
The purpose of this email is to see if you can provide guidance on what might be the appropriate steps to follow
regarding federally protected aquatic species for Phase I of the work. A review of IPaC indicates that the Neuse Rive
waterdog(NRWD)and Carolina madtom (CMT) could be potentially affected by activities at the location.
ISR information for each of these species is provided below:

SUMMARY OF HISTORIC ARCHITECTURE AND LANDSCAPES REVIEW
Description of review activities, results, and conclusions:
Review of HPO quad maps, HPO GIS information, historic designations roster, and indexes was
undertaken on October 13, 2021. Based on this review, there are no existing NR, SL, LD, DE, or
SS properties in the Area of Potential Effects, which is defined on the follow maps and follows
the study area. There are no properties over fifty years of age within the APE. There are no
National Register listed or eligible properties and no survey is required. If design plans change,
additional review will be required.
Why the available information provides a reliable basis for reasonably predicting that there
are no unidentified significant historic architectural or landscape resources in the proiect
area:
HPO quad maps and GIS information recording NR, SL, LD, DE, and SS properties for the
Durham County survey, Durham County GIS/Tax information, and Google Maps are considered
valid for the purposes of determining the likelihood of historic resources being present. There
are no National Register listed or eligible properties within the APE and no survey is required.

Project Description: The North Carolina Department of Transportation Division 5 intends to
replace the failed culvert on SR 1800, Hereford Road, over Rocky Branch/Falls Lake. No
preliminary designs were available at the time of the request for archaeological screening, but a
proposed study area was submitted with the request for cultural resources screening. For the
purposes of this review, an archaeological area of potential effects (APE) was established based
on the submitted study area. This APE is estimated to encompass 13.7 acres (more than 5.54
hectares).
SUMMARY OF CULTURAL RESOURCES REVIEW
Brief description of review activities, results of review, and conclusions:
A review of archaeological site locations and shapefiles maintained by the North Carolina Office
of State Archaeology (OSA) was conducted on November 17, 2021. An examination of cultural
resources recorded within a .5-mile radius of the proposed project reveals a large number of
archaeological sites, predominantly identified through cultural resource management projects
associated with the creation and management of Fall Lake (Cable 1991, Hardlines 1999, Fletcher
et al. 2010). These sites include: 31DH26, 31DH72-75, 31DH493, 31DH497-500, 31DH606,
31DH704, 31DH733-734, 31DH807-809, and 31DH829-832. In addition to these archaeological
sites, the former location of the James W. Creech, Sr. House (DH2269) and the Joe Holloway
House(DH2368) are recorded with the State Historic Preservation Office within this radius. Two
known cemeteries, the Creech cemetery, and the Holloway family cemetery, fall within this same
radius as well.
In the Spring of 2017,NCDOT staff archaeologists conducted an archaeological screening for the
replacement of the pipe (No. 72), on SR 1637, Redwood Road, roughly .5 mile to the northwest
of the failed culvert on SR 1800. Archaeological and physical contexts for that project were very
similar to that of the current project under consideration. Also much like the current project area,
the vicinity of Pipe No. 72 exhibited a number of nearby archaeological resources that had been
identified as part of the same Fall Lake archaeological surveys.
An examination of the United States Department of Agriculture, Natural Resources Conservation
Service (MRCS) Web Soil Survey (https://websoilsurvey.sc.eaov.usda. og v/App/HomePaae.htm)
reveals the following soil types within the proposed APE: Cartecay and Cawacla soils, 0 to 2
percent slopes, frequently flooded (Cc); Creedmoor sandy loam, 2 to 6 percent slopes (CrB);
2020 PROGRAMMATIC AGREEMENT ARCHAEOLOGY TEAM"NO ARCHAEOLOGICAL SUR VEYREQUIRED"FORM

Creedmoor sandy loam,6 to 10 percent slopes(CrQ;and White Store sandy loam, 10 to 25 percent
slopes (WsE).
(This project falls within a North Carolina County in which the following federally recognized
tribes have expressed an interest: the Catawba Indian Nation. We recommend that you ensure
that this documentation is forwarded to these tribes using the process described in the current
NCDOT Tribal Protocol and PA Procedures Manual.)
Brief Explanation of why the available information provides a reliable basis for reasonably
predicting that there are no unidentified historic properties in the APE:
As noted above, archaeological investigations in the vicinity of Falls Lake have identified
reasonably intensive patterns of human occupation throughout the prehistoric and historic periods.
Indeed, there are more than a half-dozen cultural resources within a few hundred feet of the
proposed project. However, as was the case with the pipe replacement on SR 1637, many of the
archaeological sites identified on the deflated uplands at or above the Falls Lake waterline largely
represent small lithic scatters. The current project area has been significantly disturbed within the
APE in a number of areas from landscape modification for the construction of the causeway, the
easement for utilities south of SR 1800, and soil erosion and deflation locally. An aerial
photograph of the project area shows Hereford Road passing to the south of its current alignment
in 1955; another aerial photograph dating from 1965 shows the crossing in its current alignment.
On November 19, 2021, NVCDOT archaeologists, Shane Petersen and Brian Overton, conducted
a visual inspection of the proposed APE as part of a reconnaissance investigation. On both ends
of the causeway, adjacent ridge slopes were observed to be reasonably steep with cuts from
ditchlines adjacent SR 1800 cutting into those slopes in the APE. These steep slopes are suggested
by the 2-foot contour lines based on LiDAR data and USDA soil mapping. On the eastern end of
the project, what appeared to be erosional gullies were observed on the steep slopes near the
highway facility; some of these gullies can be seen on the bare-earth terrain model based on the
QL2 LiDAR data.
Based on the contextual information and conditions observed in the field, the potential for
significant archaeological resources to be impacted by the project as currently proposed seems
very low. However, it should be noted that further review would be necessary if the APE were to
expand towards any of the currently unassessed archaeological sites, historic properties, or
portions of adjacent landforms that are less sloped and less obviously disturbed.
No further archaeological investigations are required for the project as currently defined. Should
the project area expand outside the current APE, further consultation will be necessary. The
current undertaking is considered to be compliant with Section 106 of the National Historic
Preservation Act and North Carolina General Statute 121-12(a). In the very unlikely event that
historic or archaeological remains be encountered during the course of the project completion, all
earth-disturbing activities should cease in the associated area immediately and the NCDOT
Archaeology Team should be contacted immediately.

Hereford Road (SR 1800) Emergency Pipe Removal Project—Report (January 2021)

Location:
Hereford Road (SR 1800) in Durham County crosses Rocky Branch, which is a finger of Falls Lake. Hereford Road extends
from Redwood Road (SR 1637)to Cheek Road (SR 1804) in northeastern Durham County. The structure crossing is
comprised of two 7-foot diameter corrugated metal pipes that are located under the roadway at 36.04554 deg. N
latitude and 78.776793 W deg. longitude. The specific length and location of the actual pipes cannot be determined at
this time since the structures are submerged. A bathymetric survey done on the at the site suggests the pipe structures
are located perpendicular along Hereford Road. The purpose of the pipe structures are to discharge the flow from Rocky
Branch on the southwest side of the road into Falls Lake on the northeast side and equalize the water levels.

Existing Conditions at Hereford Road:
The date of installation of the pipe structures is not definitively known. The road apparently existed as a gravel road
when adjustments were made for the Falls Lake reservoir around 1980. The existing pipe structures may have been
extended at that time (NCDOT, December 15, 1980)to obtain the typical section for the road in anticipation of the
reservoir. The road was reconstructed as a typical secondary road to NCDOT standards in Summer/Fall 1999. The pipe
structures are typically submerged and no photographs exist of the exposed pipe structures. A photograph taken at the
inlet of the structure in November 2019 likely depicts part of the headwall structure (see below photograph).

Hereford Road (SR 1800) Emergency Pipe Removal Project—Report(January 2021)

An underwater investigation of the pipes was conducted on July 1, 2019 with the following findings:
-Pipes 1 and 2 were impenetrable. Blockage by a wall of sediment was identified approximately 50 ft in from the
outlet end (northeast side of lake) and blocked by a wall of sediment.
-Section loss on ends of pipe at the inlet end (southwest side of road)with area covered by collapsed slope wall
and rip rap. Diver was unable to penetrate the inlet end due to this failure.
-Embankment failure along inlet end (southwest side of road) was 20 ft long x 20 ft wide with eight ft from edge
of pavement.
A review of the conditions by the NCDOT Geotechnical Unit (NCDOT, March 24, 2020) indicates the following:
-The subject washout/slope slough is understood to be related to a failed pipe beneath the roadway. The pipe
structures are understood to be compromised and soil is being washed away as upstream flow exits the pipes
ahead of the outlet. Some soil may also be leaking down into the pipes.
-The washout/slope slough has not changed much since a previous review in July 2019 except for the further
settling/eroding of soil from higher areas of the slope (up near the shoulder). The slope may have sloughed to a
point of pseudo stability.
-Conditions are currently stable but large rainfall events will likely cause more erosion of material and sloughing
of the slope via surface runoff from the roadway and discharge from the pipes.
Due to safety concerns associated with shoulder and guardrail fail, the Division closed the road on June 15, 2020. A
review of the conditions on January 13, 2021 at the site indicated a significant increase in the embankment failure along
the inlet end (southwest side) and new observed loss of embankment failure along the outlet end (northeast side).
Photographs from this most recent visit are presented in Appendix A.
Hereford Road and Redwood Road pipe structure history:
The failing pipe structures that convey Rocky Branch (a finger of Falls Lake) on Hereford Road are located approximately
0.6 mi from pipe structures that failed in 2016-2017 at the Panther Creek(another finger of Falls Lake) crossing along
Redwood Road. See below map:

A review of the Soil Survey of Wake County (1970, using aerial photographs from 1965) indicates both Hereford Road
and Redwood Road as some type of roadway facility, likely a gravel road with some type of apparent structures to
convey the separate stream crossings. See below photograph:

Hereford Road (SR 1800) Emergency Pipe Removal Project—Report(January 2021)

This information indicates that the two roadways and their respective pipe crossing structures are likely of the same age,
with construction dating back to prior to the impounding of Falls Lake.
As noted above,the Department identified two failed 10-goot corrugated metal pipe structures in October 2016 along
Redwood Road that convey Panther Creek. An investigation indicated that the pipe structures failed underneath the
roadway embankment resulting in the eventual formation of a large sinkhole approximately 15 feet in diameter on
Redwood Road. The Department engaged Dewberry in 2017 to provide planning and design services to support the
continued investigation of the failed pipe structures including but not limited to removal of the failed pipe structures
and replacement with a new bridge structure. Dewberry completed the Redwood Road (SR 1637) Emergency Pipe
Replacement Bridge Construction Feasibility Study (July, 2017)to investigate the following: 1) Feasible bridge channel
construction alternatives, 2) Review cost effectiveness and impacts of selected alternatives and 3) Compare alternatives
to provide an engineering basis for the Department to select a recommended alternative with support from other state
and federal agencies to allow for permitting of the project. This Feasibility Study for Redwood Road is attached to this
letter.
The current failures observed at the Rocky Branch crossing along Hereford Road are similar to those at the failed pipe
structures in 2016-2017 observed along Panther Creek crossing along Redwood Road. The Department believes that
the pipe failure mechanisms,geotechnical findings and construction constraints are similar and the Redwood Road (SR
1637) Emergency Pipe Replacement Bridge Construction Feasibility Study(now referred to as Redwood Road Feasibility
Study) can be used to assist the Department in further investigation of the current issues along Hereford Road.
Proposed Project at Hereford Road:
Conditions at the site are unsuitable for replacing the existing pipe structures with any type of replacement culvert/pipe.
The Department currently is investigating removal of the existing failing pipe structures and to provide suitable
stabilization to the stream channel. The excavated channel is expected to be at 18 ft wide at the base with 2:1 slopes
and two feet thickness of dumped Class II rip rap (underlain by geotextile) on the excavated slopes. See below sketch of
the proposed excavated channel:

Utility Considerations at Hereford Road:
An overhead Wake EMC single phase power line crosses Rocky Branch immediately upstream of the failing pipe
structures. Further investigation is necessary to determine how this power line will affect proposed construction
activities.
Geotechnical Considerations at Hereford Road:
The NCDOT Geotechnical Unit performed a Structure Subsurface Investigation on July 10, 2019 that included 12 borings
at the project site. Four borings are located along each roadway shoulder embankment (northwest and southeast side)
centered along the existing pipe structure. Four additional borings are located at the proposed locations of End Bent#1
and End Bent#2.
Borings were terminated with Standard Penetration Test (SPT) refusal in non-crystalline rock(either mudstone or
siltstone) at 28.3 ft below the roadway embankment for EB#1A, 33.2 ft at EB#1B, 28.3 ft at EB#2A and 28.4 ft at EB#213
The Structure Subsurface Investigation is attached to this letter.
Construction Alternatives as presented in the Redwood Road Feasibility Study that are applicable to Hereford Road:
Several options to isolate the work area to conduct activities in a dewatered condition were identified in the Redwood
Road Feasibility Study including various types of inflatable dams and cofferdams. Evaluation of these alternatives in the
Redwood Road Feasibility Study indicate that there were construction, hydraulic and geologic limitations at the
Redwood Road site due to the following issues:
• Water depth greater than 12 to 14 feet
• Shallow bedrock in streambed
• Presence of debris and stumps that would puncture inflatable dams
• Water flows
The Redwood Road Feasibility Study forwarded four construction methods for further review and investigation. They
include the following:
Inflatable Dam (Alternative 1)
This alternative involves installation of two large inflatable dam across the water way to isolate the work area to
construct in a dewatered condition with turbidity curtain installed to reduce downstream turbidity(see Redwood Road
Feasibility Study, Pages 8-10).
Cellular Cofferdam (Alternative 21
This alternative involves installation of steel interlocked cofferdams across the waterway to isolate the work area to
construct in a dewatered condition with a turbidity curtain installed to reduce downstream turbidity(see Redwood Road
Feasibility Study, Pages 10-12).
Wet Excavation (Alternative 3)
Wet excavation would include completion of as much "dry" excavation above the water line using conventional
excavation methods before excavation commences below the waterline. Two in-stream turbidity curtains would
7
Hereford Road (SR 1800) Emergency Pipe Removal Project—Report(January 2021)

surround the work area to prevent downstream movement of turbidity (see Redwood Road Feasibility Study, Pages 12-
13).
Modified Wet Excavation (Alternative 4)
The modified wet excavation method would be to excavate the channel in multiple stages using a braced cofferdam
system constructed within the roadway embankment for stability. This alternative minimizes, but does not eliminate,
the amount of wet excavation. Two in-stream turbidity curtains would surround the work area to prevent downstream
movement of turbidity(see Redwood Road Feasibility Study, Pages 13-15).
Comparative Analysis of Construction Alternatives/Conclusion as presented in the Redwood Road Feasibility Study
(see Pages 15-17)that are applicable to Hereford Road:
The Redwood Road Feasibility Study compiled basic information on cost, construction time, impacts, and
risks/vulnerabilities of the four alternatives with the following findings:
-All alternatives will generate impacts to the adjacent lake area due to the require debris removal and excavation of the
causeway and lake bottom necessary to install the required turbidity curtain and to construct the new channel.
-All alternatives will utilize track or barge mounted excavators, clam shell excavators or drag lines for the necessary
excavation and clearing of debris and expansion of the project footprint.
-All alternatives are vulnerable to risk of overwhelming the turbidity curtains and/or overtopping temporary dams by
rising flood levels from storm events.
-Additional vulnerabilities for Inflatable Dam (Alternative 1) and Cellular Cofferdam (Alternative 2) include potential for
the temporary dams to be damaged or difficulty with the foundation seal due to irregular bedrock profiles or bottom
strata or debris.
-The Wet Excavation (Alternative 3) and Modified Wet Excavation (Alternative 4) have less area impact and less
disturbed area than the other alternatives.
-The construction time to excavate the channel with Wet Excavation (Alternate 3) is the least of all the alternatives
examined.
-The cost for channel construction with Wet Excavation (Alternate 3) is the least of all the alternatives examined.
Division 5 and Dewberry staff conducted a meeting with representatives of the USACE, NCWRC and NCDEQ DWR on
June 13, 2017 to present the findings of the Redwood Road Study(specifically the four alternatives)to determine a
recommended alternative for removal of the failed pipe structures. All parties agreed that the recommended
alternative for removing the failed pipe structures is Wet Excavation (Alternative 3).
Conclusion for proposed Department activities at Hereford Road:
The Department believes that the geotechnical findings and construction constraints along Redwood Road fully detailed
in the Redwood Road Feasibility Study are very similar to those that will be experienced along the pipe and slope failures
currently observed along Hereford Road. These roadway facilities and the associated crossing structures at the two sites
are likely of the same age. The Department requests agency concurrence using Wet Excavation (Alternative 3)for
removal of the failed pipe structures and channel construction at the pipe structures along Hereford Road. This
concurrence will be used for permitting and construction of the project. As previously noted, Hereford Road was closed
to traffic on June 15, 2020.
