Eagles Nest Street West Project
Williamson County, Texas
Introduction
The City of Round Rock (City) has contracted with Halff to conduct an intensive archeological survey for
the proposed Eagles Nest Street project in Round Rock, Williamson County, Texas (Attachment A, Figure
1). The proposed project consists of a circa (ca.) 0.8-mile (1.3-kilometer [km]) long and 120-foot (ca. 36.6-
meter [m]) wide (10.1-acre) new roadway from North Mays Street to ca. 1,900 feet (ca. 580 m) west of
Interstate Highway 35 (IH-35) within the Round Rock city limits. The proposed roadway would bridge
Chandler Branch and IH-35 as shown in Attachment A, Figures 2 and 3.
Because the project is being developed by the City, a political sub -entity of the State of Texas, it falls under
purview of the Antiquities Code of Texas (Title 9, Chapter 191 of the Texas Natural Resources Code), which
requires that the Texas Historical Commission (THC) review actions that have the potential to impact
archeological historic properties within the public domain. Proposed construction depths are greater than 3
feet (ca. 91 centimeters [cm]) within portions of the planned bridge footprint and less than 3 feet (ca. 91 cm)
in the remainder of the roadway. It is Halffs understanding that the project does not include any federal
funding or permitting that would otherwise require compliance with Section 106 of the National Historic
Preservation Act. The project area reviewed for this study is illustrated in the map figures included in
Attachment A.
Halff conducted a desktop review of local environmental and cultural resources background information to
determine the potential for the project area to contain archeological historic properties eligible for listing on
the National Register of Historic Places (NRHP) or State Antiquities Landmark (SAL) designation. The
Texas Archeological Sites Atlas maintained by the THC and Texas Archeological Research Laboratory
(Atlas) was reviewed to determine whether any archeological historic properties, NRHP properties/districts,
SALs, Official Texas Historical Markers (OTHMs), cemeteries and previous cultural resources surveys are
documented within or adjacent to the project area. Background research also included a review of local
soil, geologic and predictive modeling information to evaluate the potential for buried archeological deposits.
Historic U.S. Geological Survey (USGS) topographic maps, historic aerial photography and Light Detection
and Ranging (LiDAR) data were reviewed to evaluate the potential for above -ground historic -age resources
in the project area.
This document is intended to accompany the Antiquities permit application submitted for an intensive
archeological survey of the project area. This scope of work summarizes the results of the background
research performed for the proposed project and outlines the methodology developed for the intensive
archeological survey for THC review and approval.
Environmental Setting
The project is mapped within the Brazos River drainage basin (TWDB 2023) and Blackland Prairies
ecological region (TPWD 2023). The project setting is that of a mixed wooded and open terrain bisected by
North Mays Street, IH-35, and a stream crossing named Chandler Branch. According to the USGS Round
Rock, Texas Topographic Quadrangle map, the project is on uplands ranging from 750 to 780 feet above
mean sea level that flank the low lying and frequently flooded valley of Chandler Branch (see Attachment
A, Figure 2). Recent aerial photography depicts a riparian setting within the Chandler Branch valley and
mostly open prairie along the uplands to the west. The primary development within the project area consists
of the IH-35 corridor and North Mays Street (see Attachment A, Figure 3). The surrounding area is devoted
primarily to commercial land use_ In addition, the western project terminus is on undeveloped land according
to recent aerial photography.

Soils and Geology
A review of the Natural Resource Conservation Service Web Soil Survey (NRCS 2023) revealed that the
project area is composed of four soil units, which are described below in Table 1. A map showing the soil
unit distribution is provided in Attachment A, Figure 4. According to the Geologic Atlas of Texas (USGS
2023a), the underlying geology is composed of the Cretaceous -age Del Rio Clay and Edwards Limestone
(Map Unit Ked) formations. These map units are described below in Table 2 and a map showing their
distribution is provided in Attachment A, Figure 5. According to the Federal Emergency Management
Agency (FEMA) Flood Insurance Rate Map data, the portion of the project area that encompasses the
banks of Chandler Branch overlaps with an area designated as a flood zone (see Attachment A, Figure 4).

Potential Archeological Liability Man Data
The Texas Department of Transportation (TxDOT) Potential Archeological Liability Map (PALM) for the
Austin District was reviewed to evaluate the potential for shallow and deeply buried archeological deposits
with integrity. In general, the PALM data indicate an overall moderate potential for shallow and deep
archeological deposits (Map Unit 5) in the project area. A high potential for such deposits (Map Unit 9) is
featured along the lower terraces and channel of Chandler Branch_ A breakdown of the PALM data for the
project area is below in Table 3 and a map showing the Map Unit distribution is provided in Attachment A_

Cultural Setting
Central Texas is generally considered to have a high potential for Indigenous archeological sites and
materials due in large part to the suitability of native Edwards Plateau chert for toolmaking and rich biotic
resources afforded by abundant natural springs. The archeological record in Central Texas is characterized
by extensive chert quarrying and tool -production sites and ubiquity of burned rock middens (Black 1989;
Collins 2004). In general, the archeological chronology of Central Texas spans from the first well -
established human occupations occurring in the Paleoindian Period approximately 13,000 years ago to the
time of Indigenous contact with European explorers in the 161h century.
Atlas Review
A review of the Atlas conducted on December 12, 2023 revealed that the project area contains one
previously recorded archeological site, 41 WM239, which is eligible for listing on the NRHP and SAL
designation. No other listed NRHP districts/properties, cemeteries or OTHMs are documented in or
adjacent to the project area. A portion of the project area intersects with a previous survey conducted in
2016 on behalf of Williamson County for the North Mays Street Extension project. Table 4 lists and
describes the cultural resources documented within a 1-km (0.6-mile) radius of the project. A map showing
these resources and the previous surveys performed in the surrounding area is included in Attachment A_

Site 41 WM239
Site 41 WM239 was most recently recorded in 1984 by Prewitt and Associates. According to the Atlas
record, the site was documented originally in 1959 ahead of IH-35 construction and later in 1964 by several
amateurs and previously designated with the trinomial 41WM15. The project area intersects with the
southern portion of the mapped site boundary. which encompasses the east and west banks of Chandler
Branch. The full site boundary is at least 800 m north -south by 600 m east -west. As outlined above in Table
4, the diagnostic stone tool assemblage contains primarily dart points from the Early to Late Archaic.
The site is situated on the low terraces of Chandler Branch with burned rock middens observed on a high
terrace north of Chandler Branch_ The burned rock middens were found on the surface and have
purportedly been looted prior to and after the site's original documentation. The 41 WM239 record describes
one midden as 24 m in diameter, 1.2 m high and moderately looted and another measuring 70 cm high and
partially removed by previous parking lot construction. Based on the available data, the site represents
repeated occupation during the Archaic period as reflected in the stone tool assemblage and burned rock
midden complex.

Subsequent land use in the project area over time includes the extension of North Mays Street and further
commercial development to the east and west. The sections between North Mays Street and IH 35 appear
to retain a wooded and undeveloped setting along Chandler Branch. In addition, the section from IH 35 to
the western terminus remains undeveloped. The historical map review revealed a low potential for extant
historic structures. The portions of the project area that were not developed over time have a moderate to
high potential for buried and intact archeological deposits given the alluvial setting, and local soil, geologic,
PALM and Atlas data.
UDAR Data
LiDAR data were used in conjunction with historic aerial imagery and topographic maps to characterize the
local landscape features. Depending on the elevation or relief they create, cultural features such as
buildings, walls, or other structures may appear as deviations from the surrounding terrain and can be
identified by contrasting shades of gray. The local LOAR data show no other human -made features in the
project area other than the IH-35 and North Mays Street corridors. Nearby modern commercial development
is depicted in the surrounding area and the Chandler Branch valley is depicted as darker shades of gray
(Attachment A, Figure 9). The upland terrain west of IH-35 is also reflected in the LiDAR data.
Methodology
The results of the background research were referenced in the development of the survey methodology to
ensure that a sufficient level of investigation will be conducted to identify all archeological historic properties
potentially affected by the proposed project. The intensive archeological survey will conform to the Council
of Texas Archeologists Archeological Survey Standards for Texas (Survey Standards) and performed by
Halff archeologists, Annie Carter and Josh Cutler who meet the U.S. Secretary of the Interior (SOI)
Professional Qualification Standards for Archaeology and Historic Preservation under the supervision of

historic resources as evidenced by the historical map reviews, an architectural assessment will not be a
component of the survey.
Components of the archeological survey may include pedestrian reconnaissance, shovel testing, backhoe
trenching, site documentation, artifact inventories, and digital photography. All exposed surfaces will be
examined for evidence of archeological materials. The excavation of shovel tests will be done on a
judgmental basis and conducted where the APE exhibits potential to contain buried and undisturbed
archeological deposits. Given the location of NRHPISAL eligible site 41WM239 within and adjacent to the
project area, the survey will focus on evaluating the site's condition and eligibility potential within the
proposed bridge and roadway footprints. The site will not be investigated outside of the current project area.
Pedestrian reconnaissance within the section of the project between North Mays Street and IH-25 was
performed on October 13, 2023. During the field visit, the portion of site 41 WM239 that overlaps with the
project area was carefully walked over to check for cultural materials on the surface. No such materials or
burned rock features were observed on the surface within the project area.
The Survey Standards for the proposed 0.8-mile (1.3-km) long project area require a minimum of thirteen
shovel tests placed at an interval no greater than 100 m (ca. 300 feet). Per the Survey Standards, shovel
tests will be excavated in settings that have potential for buried archeological materials, except on slopes
greater than 20 percent or in settings with evidence of significant ground disturbance. Shovel tests will be
30 cm (ca. 1 foot) in diameter and excavated to the lesser of 80 cm (ca. 2.6 feet) below the surface or base
of Holocene -age deposits. All excavated soil matrices will be screened through 025-inch (0.64-cm)
hardware cloth or hand -sorted if clay and moisture content require. The location of each shovel test will be
documented using a Global Positioning System (GPS) capable of sub -meter accuracy. Soil/sediment depth
and composition, and the presence/absence of archeological materials will be recorded on standardized
forms for each shovel test, which will be backfilled upon completion. If previous ground disturbance
precludes the excavation of shovel tests, GPS data points will be recorded at each location along with
photographs and descriptions of the disturbance. Shovel test intervals will be adjusted as needed to avoid
disturbed areas while adhering to the shovel test schedule. All photograph locations will be mapped using
GPS.
Shovel tests will be augmented with backhoe trenches in areas with deep (i.e., greater than 3 feet [ca. 91
cm]) proposed construction depths, which consist of portions of the project area that overlap with the
proposed bridge footprint and 41 WM239. The trenches will be placed on a judgmental basis to
accommodate terrain, vegetation, and modern cultural features and care will be taken to avoid unnecessary
impacts to site 41 WM239. The number of trenches will be dependent on field observations as they pertain
to disturbed and intact soils and the presence/absence of cultural materials. However, Halff will make a
good faith effort to place at least four trenches within the project area where it overlaps with proposed deep
construction depths associated with the bridge footprint. Due to its upland setting, the portion of the project
area west of IH-35 will undergo only shovel testing.
Halff archeologists will monitor all trenching activity while excavations are in progress. Trenches will be a
minimum of 60 cm (24 inches) wide, 4 m (ca. 13 feet) long, and excavated to depths that exposed the base
of Holocene -age deposits. During each trench excavation, one 5-gallon bucket containing excavated fill
from every third backhoe bucket load will be screened through 0.25-inch (0.64-cm) hardware mesh.
Stratigraphic descriptions of a cleaned 1-m (ca. 3-foot) wide profile will be recorded, with photographs taken
with a scale for each recorded profile.
Standard safety protocols will be employed throughout the trenching excavation and documentation
process, including the stepping back of side walls for trenches that exceed 1 m (ca. 3 feet) in depth. In
ME

addition, ramps will be excavated at each end of the trench to allow safe entrance and exit during the
documentation process. The field personnel shall not enter any trenches until after the appropriate safety
protocols are in place and the excavation machine is powered off. No personnel shall enter trenches with
benched walls exceeding 3 feet (ca. 1 m) in depth. All trenches will be backfilled, and the ground returned
to its original condition to the extent possible following the excavation and documentation of each trench.
Site Recording and Assessment
For the purposes of the intensive archeological survey, an archeological site will be defined as containing
cultural materials or features that are at least 50 years in age or older. More specifically, a site will be
defined as containing at least one of the following criteria:
1. a single cultural feature observed on the surface or exposed in shovel testing,
2. five or more surface artifacts within a 15-m (ca. 50-foot) radius,
3. two or more positive shovel tests/trenches located within 30 m (ca. 100 feet) of each other.
Upon the identification of an archaeological site, the boundaries are delineated based on the distribution of
artifacts and features found on or beneath the surface. Per the Survey Standards, a minimum of six shovel
tests are excavated at no greater than 15-m (ca. 50-foot) intervals until two negative shovel tests in each
cardinal direction or landform/project limits are reached. If shovel tests and other field observations indicate
a negligible potential for buried archaeological materials, site boundaries are delineated based on the
surface distribution of artifacts and/or features.
Where sites are found at a depth greater than 80 cm (ca. 2.6 feet) below the surface, a minimum of four
trenches are used for site definition unless other criteria can be used to constrain site size. Additional and
strategically placed shovel tests and trenches are excavated as needed to adequately sample site deposits
and are placed with the intent to avoid unnecessary damage to the site. All archeological features and
horizons observed in trench profiles will be mapped, recorded, and photographed with a scale. A 30- by
30-cm (ca. 1- by 1-foot) test column will be excavated where such archeological deposits are observed,
extending from the ground surface to the base of Holocene -age deposits. Soil/sediment from the column
will be removed in 5-cm (ca. 2-inch) levels and screened.
The survey will employ a non -collection strategy, meaning all artifacts observed in the project area are
documented in the field and left where they were found. However, certain diagnostic materials may be
collected as needed to evaluate site chronology and significance_ All encountered sites are documented on
standardized forms with boundaries and significant featureslartifact localities mapped in the field with a
GPS capable of sub -meter accuracy. The site data collected in the field are sufficient for a preliminary
evaluation of the potential for NRHP/SAL eligibility. Electronic TexSite forms are completed for each
documented site and submitted to the Texas Archeological Research Laboratory with site boundary
shapefiles for permanent trinomial assignment_
Survey Report
Halff will prepare and submit a draft report that summarizes the findings of the archeological survey. The
report will conform to the Secretary of the Interior's Guidelines for Archaeology and Historic Preservation
and provide recommendations regarding any additional cultural resources work requirements with
appropriate justifications. Following a period of client review, the draft report will be submitted to the THC
for review. After addressing any agency comments, Halff will submit a final report to the client and furnish

the THC with one final report copy containing the plotted locations of any sites recorded and one copy that
excludes the site location data.
Curation
Pursuant to 13 TAC 26.17, and after acceptance of the final report by the THC, the survey report, field
records, photographs and collected artifacts will be prepared for permanent curation at the Center for
