The proposed project consists of a circa (ca.) 0.4-mile (643.7-meter [m]) long and 120-foot (ca. 36.6-m) wide (5.6-acre) new roadway from the existing western terminus of Eagles Nest Street to North Mays Street within the Round Rock city limits (Attachment A, Figures 2 and 3). Proposed construction depths are less than 3 feet (ca. 91 centimeters [cm]) throughout the proposed roadway. 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. It is Halff's 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 to undergo an intensive archeological survey 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 APE and surrounding vicinity. 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 mostly open and undeveloped terrain. According to the USGS Round Rock, Texas Topographic Quadrangle map, the eastern half of the project area lies on an upland with elevations ranging from 750 to 780 feet above mean sea level and the western half comprises the low eastern terraces of Chandler Branch (see Attachment A, Figure 2). Recent aerial photography depicts a mostly open setting with moderate wooded areas in the western half near North Mays Street. The primary development within the project area consists of a section of Eagles Nest Street to the east and North Mays Street to the west. Commercial facilities are also depicted to the east and north (see Attachment A, Figure 3). The surrounding area is devoted primarily to commercial land use. !u halff - Eagles Nest Street East Project Williamson County, Texas Soils and Geology A review of the Natural Resource Conservation Service Web Soil Survey (NRCS 2023) revealed that the project area is composed of five 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 Georgetown (Map Unit Kdg) and Pleistocene -age fluviatile terrace deposits (Map Unit Qt). 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 western portion of the project area overlaps with an area designated as a flood zone (see Attachment A, Figure 4).

In general, the PALM data indicate a moderate deep potential (Map Units 2, 5 and 8) in the majority of the project area. 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, Figure 6. Table 3: PALM unit descriptions and frequencies.

The archeological record in Central Texas is characterized by extensive chert quarrying and tool -production sites and ubiquity of burned rock middens (Slack 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 4, 2023 revealed that the project area contains no previously recorded archeological sites. Two archeological sites and one OTHM are recorded within 1 km (0.6-mile) of the project area. Site 41 WM239 is eligible for listing in the NRHP and is mapped some 100 m to the west. Additionally, no listed NRHP districtslprope rties or cemeteries are documented in or adjacent to the project area. The western project area terminus 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 ee .haLff- Eagles Nest Street East Project Williamson County, Texas 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, Figure 7.

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 41 WM15. 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. Historic Map Review A summary of the historic topographic quadrangle maps (USGS 2023b) and aerial photographs (NETR 2023) reviewed for the project are summarized below in Table 4.

The above -referenced structure and road Rural and mostly 1954 Aerial Photograph are visible near the eastern project undeveloped terminus pastureland Rural and mostly 1962 Aerial Photograph Same as 1954 aerial photograph undeveloped pastureland Subsequent land use in the project area over time includes the extension of North Mays Street and further commercial development to the east. The structure shown on the historical topographic map and aerial photographs listed in Table 5 is no longer visible on recent aerial photography (see Attachment A, Figure 3). The historical map review revealed a low potential for above -ground historic structures and a moderate potential for historic -age archeological materials in the project's easternmost portion given the former historic structure. The western half of the project area appears undeveloped over time which is conducive to the preservation of archeological sites, if present. UDAR Data LiDAR data were used in conjunction with historic aerial imagery and topographic maps to establish an understanding of 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 LiDAR data show no human -made features in the project area. Nearby modern commercial development is depicted to the north and the Chandler Branch valley is depicted as darker shades of gray to the west (Attachment A, Figure 9). 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 (SO1) Professional Qualification Standards for Archaeology and Historic Preservation, and Mike Mudd who meets the SOI standards and professional qualification requirements for Principal Investigator (13 Texas Administrative Code [TAC] 26.4). Given the low potential for above -ground historic resources as evidenced by the historical map reviews, an assessment of effects to such resources will not be a component of the survey. In addition, backhoe trenching is not a component of the survey given the shallow construction depths and low potential for deeply buried Holocene -age deposits. Components of the archeological survey may include pedestrian reconnaissance, shovel testing, site documentation, artifact inventories, and digital photography. All exposed surfaces will be examined for .ee halff - Eagles Nest Street East Project Williamson County, Texas evidence of archeological materials. The excavation of shovel tests will be done on a judgmental basis and conducted where the project area exhibits potential to contain buried and undisturbed archeological deposits. The Survey Standards for the proposed 0.4-mile (643.7-m) long and 120-foot (36.6-m) wide project require a minimum of six shovel tests placed at an interval no greater than 100 m (300 feet) along one transect. 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 0.25-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 backfiiled 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. Mechanized trenching is not a recommended component of the survey given the shallow (i.e., less than 3 feet) proposed construction depths throughout the project area. 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. three or more surface artifacts within a 15-m (ca. 50-foot) radius, 3. two or more positive shovel tests located within 30 m (ca. 100 feet) of each other. Upon the identification of an archeological 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. 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 significance. All encountered sites are documented on standardized forms with boundaries and significant features/artifact 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. iB haLff 6 Eagles Nest Street East Project Williamson County, Texas 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 City 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 City 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 Archaeological Studies located at Texas State University in San Marcos, Texas. halff� 7 Eagles Nest Street East Project Williamson County, Texas References Black, Stephen L. 1989 Central Texas Plateau Prairie.
