A Phase I Cultural Resources Survey of the 8-Mile Project, Brazoria County, Texas

Perennial Environmental Services, LLC (Perennial), on behalf of Phillips 66 Pipeline LLC (P66), conducted an intensive cultural resources survey of the proposed 8-Mile Project located in Brazoria County, Texas . The proposed Project will consist of an approximately 1,275.3-acre (ac) (516.1-hectare [ha]) facility designed to service the transportation of Natural Gas Liquids (NGLs) and will include a railroad track loop, storage, railcar offloading tracks, an administrative building, and other structures necessary for operation of the facility. The proposed Project is located within the jurisdictional boundary of the U.S. Army Corps of Engineers (USACE) Galveston District. The Project may require the usage of a Nationwide Permit (NWP) issued by the USACE, and as such, a cultural resources survey was conducted for the 1275.3 ac (516.1 ha) Project area in accordance with Section 106 of the National Historic Preservation Act (NHPA) (36 CFR Part 800). The survey was designed to inventory and assess cultural resources across the Project. These efforts involved both surface and subsurface archaeological survey. The area of potential effect (APE) is considered the entirety of the Project area. The APE measures approximately 1275.3 ac (516.1 ha). Perennial conducted the intensive Phase I cultural resources survey within the boundary of the Project APE. Zachary Overfield served as the Principal Investigator (PI) for the Project and supervised all aspects of the cultural resources survey. The fieldwork was conducted by Tessa Noble, Mary Noell, Jacob Cumberland, Patrick Gainey, Anne Marie Fraley, and Allyson Walsh on December 4-12, 2014 and Amy Goldstein, Kirsten Atwood, and Zachary Overfield on February 22-24, 2016. The background review identified two National Register listed properties (Marmion’s gazebo and Palapa table) northwest of the Project area. Both properties are located upon the historic James Richard Marmion Estate, which has not been evaluated in its entirety for its NRHP eligibility (Atlas 2016). The gazebo and Palapa table were created by noted sculptor Dionicio Rodriguez and qualify under criterion C as the work of a master. The gazebo is located 0.4 mi (0.7 km) northwest of the Project area and the table is located 0.6 mi (1.0 km) northwest of the Project area. The properties do not lie in the Project viewshed as bottomland hardwood forest obscures the northwestern boundary. Additionally, rail facilities will not drastically alter the character of the viewshed due to the prior establishment of a railroad and rail facilities in the immediate area. These properties are a sufficient distance outside of the Project APE and will not be impacted by Project construction activities. The field survey resulted in entirely negative findings with no cultural resources observed along the ground surface or within any of the 395 shovel tests excavated across the Project. Overall, the Project area was found to be dominated by cleared pastureland that was once bottomland hardwood forests. Multiple pipeline corridors bisect the property, and inundation was widespread during the 2014 and 2016 investigations. Based on the extent of the survey efforts and the entirely negative results of the investigation, it is the professional opinion of the Principal Investigator that the Project will have no adverse effect on significant cultural resources listed on or considered eligible for listing on the NRHP. No further work is recommended for the Project

Cultural Resources Survey of the Proposed CPS Energy Shepherd Transmission Line Project, Bexar County, Texas

SWCA Environmental Consultants (SWCA) conducted a cultural resources investigation on behalf of CPS Energy for the proposed 5.6-mile-long (9-kilometer [km]-long) Shepherd Transmission Line Project in Bexar County, Texas (Project). The Project will involve installing new overhead electric transmission monopoles within west San Antonio. The Project is currently not subject to Section 106 of the National Historic Preservation Act (NHPA) but is subject to the Antiquities Code of Texas (ACT) and Historic Preservation and Design Sections of San Antonio’s Unified Development Code, both closely aligned to NHPA standards. The purpose of the investigation was to identify any substantial cultural resources sites located within the Project area, establish vertical and horizontal site boundaries as appropriate with regard to the Project area, and evaluate the significance of any sites recorded within the property. All work was done in accordance with the Archeological Survey Standards for Texas as set forth by the Council of Texas Archeologists (CTA) and adopted by the Texas Historical Commission (THC). The direct area of potential effects (APE) totals 69.3 acres (28.0 hectare), derived from the approximately 5.6-mile-long (9.0-km-long) proposed Project alignment and its 75- to 100-foot-wide (22.9- to 30.5-meter-wide) corridor. The indirect APE examined was the direct line of sight from planned Project monopoles and wires with the potential to impact the visual viewshed of historic buildings. Prehistoric archaeological site 41BX2270 was newly identified during the investigation. Site 41BX2270 is a diffuse lithic artifact scatter isolated to the ground surface. The artifact assemblage is representative of a lithic procurement site ubiquitous across the region. Due to the paucity of cultural materials, lack of temporally diagnostic artifacts or features, and absence of buried prehistoric materials, SWCA assesses the portion of site 41BX2270 within the Project area as not eligible for the National Register of Historic Places or for designation as a State Antiquities Landmark and no further work is recommended. SWCA has made a reasonable and good faith effort to identify significant cultural resources within the APE. All investigations were conducted in accordance with the regulations and guidelines of the ACT, THC/CTA, and Section 106 of the NHPA

Cultural Resources Investigation Of The Green Valley Special Utility Distinct Weil Road Fill Line Project, Guadalupe County, Texas

At the request of Trihydro Corporation, SWCA conducted a cultural resources investigation of the 3.2-mile (5.1 kilometer [km]) Green Valley Special Utility District (GVSUD) Weil Road Fill Line Project area (Project) located in the extra-territorial jurisdictions of the Cities of Santa Clara and Cibolo, Guadalupe County, Texas. The Project alignment traverses privately owned land and existing roadways between the Canyon Regional Water Authority (CRWA) Wagner Booster Pump Station at 1084 West FM 78 in Cibolo, and the GVSUD Booster Pump Station at Weil Road in Marion. The southern terminus of the Project alignment is located approximately 2.5 miles (4.02 km) west of Cibolo and approximately 2.75 miles (4.43 km) east of Marion. Due to the receipt of United States Department of Agriculture (USDA) Rural Development (RD) of Texas federal funding, the Project must comply with Section 106 of the National Historic Preservation Act (NHPA) and its implementing regulations (36 Code of Federal Regulations [CFR] 800). Additionally, the Project involves political subdivisions of the State of Texas (CRWA and GVSUD) and the Antiquities Code of Texas (ACT) applies as the Project’s activities will involve more than 5 acres / 5,000 cubic yards of land disturbance, or potentially affect known archaeological sites. Investigations included a background and historic map review, and an intensive pedestrian survey with shovel testing within the Project alignment. The background literature review determined one previously conducted cultural resources investigation intersects the Project area near its southern terminus, site 41GU64, a prehistoric lithic quarry that SWCA revisited during the investigation. The site was recorded in 2000 by a Texas Historical Commission (THC) archaeological steward and the assemblage was reported to comprise burned rock, tested chert cobbles, bifaces, hand axes, and polyhedral cores. The SWCA revisit of site 41GU64 within the Project area found it consists of a very low frequency of prehistoric lithic artifacts. Shovel tests encountered no subsurface cultural materials and no cultural features or temporally diagnostics were encountered on the ground surface within this portion of the site. Due to the paucity of cultural materials, lack of temporally diagnostic artifacts or features, and lack of buried cultural materials SWCA assesses the portion of site 41GU64 within the Project area as not eligible for the National Register of Historic Places (NRHP) or designation as a State Antiquities Landmark (SAL). Newly recorded site 41GU199 is a low-density, mid-twentieth-century, historic-age site comprised of an Aermotor windmill, pump shed, cement-capped well, and a historic-age artifact scatter constrained to the ground surface within a drainage. All aboveground features are located outside of the Project area and will not be impacted by Project construction activities. Overall, the observed artifacts are confined to the surface, have likely been displaced from their original context, and represent common trash and debris. The windmill and pump shed are common elements on the mid-twentieth-century landscape, do not possess significant architectural value, and cannot be associated with significant themes in American history. The windmill, pump shed, and well are located outside the Project construction area. Additionally, the site archaeological component lacks integrity, as the artifacts (N= 7) are solely within a disturbed context (drainage channel). Based on these factors the overall research potential of 41GU199 is low. As such, the portion of the site within the Project area is assessed not eligible for the NRHP and no further work is recommended. SWCA also identified one historic-age isolated artifact find during pedestrian survey of the Project area. IF01 consists of the solarized base of a mid-twentieth-century Ball brand jar found on the ground surface. This cultural resource does not meet the criteria for designation as an archaeological site and no further work is warranted. In accordance with 33 CFR 800.4, SWCA has made a reasonable and good faith effort to identify cultural resources properties within the Project area. No properties were identified that may meet the criteria for listing in the NRHP according to 36 CFR 60.4, or for designation as an SAL according to 13 Texas Administrative Code 26.10. SWCA requests THC concur with a determination of No Historic Properties Affected for the undertaking and that no additional cultural resources investigations are warranted within the Project area, as currently defined

Final Report A Phase I Cultural Resources Survey of the Break Point Project Fort Bend County, Texas

Perennial Environmental Services, LLC (Perennial), on behalf of Gulf South Pipeline Company, LP (Gulf South), a subsidiary of Boardwalk Pipeline Partners, LP (Boardwalk), conducted an intensive cultural resources survey of the proposed Break Point Project (Project) located in Rosenberg in Fort Bend County, Texas. The Project will involve the hydrostatic testing of the existing line. The hydrostatic test will require temporary workspace in order to complete the proposed activities. The proposed Project construction will include the excavation of the existing pipeline and in order to complete a hydrostatic test of the line. Temporary workspace within the defined Project area will be utilized for construction vehicular traffic and equipment storage during the testing activities. Ground disturbance will be minimal outside of the existing corridor; however, limited excavation activities will be necessary at the margins of the existing right of way (ROW). The proposed Project may require the usage of a Nationwide Permit (NWP) issued by the US Army Corps of Engineers (USACE). As such, portions of the Project fall under the jurisdiction of the USACE. Additionally, the proposed Project is regulated by the Federal Energy Regulatory Commission (FERC). Cultural resources surveys were conducted for the approximately 3.4-acre Project area in accordance with Section 106 of the National Historic Preservation Act (NHPA). The survey was designed to inventory and assess cultural resources across the Project. These efforts involved both surface and subsurface archaeological survey. The area of potential effect (APE) is considered the entirety of the Project area. The APE measures approximately 3.4 acres with depths of impact extending to the depth of the existing pipeline (4.0 to 6.0 ft [1.2 to 1.8 m]) within the permanent easement, and 0.6 to 1.0 ft (0.1 to 0.3 m) within the temporary workspace areas. Perennial conducted the intensive Phase I archaeological investigation within the boundaries of the Project. Abby Peyton served as the Principal Investigator (PI) for the Project and Zachary Overfield, Michael Maddox, and Miles Martin conducted the fieldwork on January 22, 2016. The survey investigations resulted in entirely negative findings with no cultural resources observed along the ground surface or within any of the ten shovel tests excavated across the Project. Overall, the Project area was found to be covered by bermudagrass and small stands of hardwoods and scrub brush. The typical shovel test profiled consisted of a dark grayish brown sandy loam from (0-11.8 in [0-30 cmbs]) on top of a gray clay (11.8-39.4 [30-100 cmbs]). Based on the negative survey results recorded during the investigation, it is the professional opinion of the Principal Investigator that the Project will have no adverse effect on significant cultural resources listed on or considered eligible for listing on the NRHP. No further work is recommended for the Project

Cultural Resources Investigation of the CPS Energy Interstate Highway 10 / Loop 1604 to FM 1518 Project, Bexar County, Texas

CPS Energy retained SWCA Environmental Consultants (SWCA) to complete an intensive cultural resources survey for the Interstate Highway (IH) 10 / Loop 1604 to Farm-to-Market Road (FM) 1518 Project (Project). The Project consists of the installation of a 3.44-mile (5.53-kilometer) long steel supply gas main in eastern Bexar County, Texas. The total size of the proposed area of investigation is 22.9 acres (9.3 ha) in extent, which represents the area of potential effects (APE) for the Project. The Project area is located parallel to IH-10 between Loop 1604 and Graytown Road, with sections also paralleling Loop 1604 and Graytown Road. Most of the Project area falls within the city limits and extraterritorial jurisdiction of San Antonio, Texas. The Project requires an Antiquities Code of Texas (ACT) permit since it will involve more than 5 acres and/or 5,000 cubic yards of land disturbance. The ACT is administered by the Texas State Historic Preservation Office, known as the Texas Historical Commission (THC). The purpose of this investigation was to identify and assess any cultural resources, such as historic and prehistoric archaeological sites and historic buildings, structures, objects, and sites (such as cemeteries) that might be located within the boundaries of the Project area. All investigations were conducted in accordance with the ACT and standards and guidelines established by the THC and Council of Texas Archeologists. The cultural resources investigation was conducted under ACT Permit No. 8395. The cultural resources investigation consisted of a thorough background literature and records review. Field investigations consisted of an intensive pedestrian survey augmented by shovel testing. The background review determined that one previously identified cultural resource (site 41BX1693) is located within the Project area. Site 41BX1693 is a lithic artifact scatter of unknown temporal association located within a plowed field. The initial investigation of 41BX1693 observed cultural materials on the surface and subsurface (plow zone) identified through shovel tests and backhoe trenching efforts. SWCA conducted a site revisit to 41BX1693 and observed cultural lithic materials present on the surface and within the plow zone. SWCA extended the site boundary to the northeast and southwest. SWCA did not identify any cultural features or diagnostic artifacts during the revisit. The portion of site 41BX1693 within the Project area does not possess research potential beyond its locational data and does not meet the criteria for designation as a State Antiquities Landmark (SAL). The SWCA investigation also recorded one prehistoric archaeological site (41BX2277) within the Project area. Site 41BX2277 consists of a light scatter of lithic debitage and tested cobbles/cores across a disturbed land surface. The artifacts have likely been secondarily deposited from a site located uphill to the northwest, which is outside of the Project area. SWCA did not identify any cultural features or diagnostic artifacts within the portion of 41BX2277 within the Project area. It is the professional opinion of SWCA that 41BX2277 does not possess research potential beyond its locational data and does not meet the criteria for designation as a SAL. In accordance with the ACT, SWCA has made a reasonable and good faith effort to identify cultural resources within the Project area. No archaeological sites or above-ground historic resources were identified within the Project area that may meet the criteria for designation as a SAL according to 13 Texas Administrative Code 26.10. SWCA recommends no additional cultural resources investigations within the Project area, as currently defined

Cultural Resources Report For The Mission Road Archaeological Scraping Project, Bexar County, Texas

The City of San Antonio (COSA) Public Works Department retained Pape-Dawson Engineers, Inc. to conduct cultural resource investigations for proposed road improvements along Mission Road and Acequia Road (i.e., the Project) within San Antonio, Bexar County, Texas. The Project consists of the installation of brick pavers and continuous illumination assemblies, electrical service, and underground infrastructure along both sides of Mission Road from SE Military Drive to the San Antonio River and along Acequia Road from Mission Road to Ashley Road. The added alternate to the Project includes the construction of a shared-use path along the east side of Mission Road from SE Military Drive through Stinson Airport, sidewalk along both sides of Mission Road from Cadmus Street (99th Street) to Acequia Road, sidewalk along the east side of Mission Road from Acequia Road to the San Antonio River, and sidewalk along the west side of Acequia Road from Mission Road to Ashley Road. A culvert system located mid-block along Mission Road will be removed, widened and extended, and replaced within the existing right-ofway (ROW). Existing underground utilities (water and sewer) will require surface adjustments to meter boxes, valve boxes, and manholes. One sewer cleanout may require both horizontal and vertical adjustments due to movement over time. As a result of the proposed improvements described above, modifications to surface drainage ditches and driveways will be required to maintain proper movement of surface runoff. As the Project is located within the COSA city limits and River Improvement Overlay District 6, the Project requires compliance with local regulations. At the municipal level, the Project must comply with Article 6, Historic Preservation and Urban Design, of the Unified Development Code (§ 35-630 to 35-634) as implemented by the COSA Office of Historic Preservation (COSA OHP). In addition, the proposed Project is within ROW owned by the City, a political subdivision of the state of Texas, which requires compliance with the Antiquities Code of Texas as implemented by the Texas Historical Commission (THC). No federal permitting or funding is anticipated for the Project; therefore, compliance with Section 106 of the National Historic Preservation Act is not necessary. Should any human remains and/or an abandoned or unknown cemetery be encountered during the Project, the Project will also comply with Chapters 711 and 715 of the Texas Health and Safety Code. All proposed improvements will be located within existing Mission Road and Acequia Road ROWs measuring 18 acres (7.3 hectares [ha]) (Project Area). The Project Area includes a total of 2.1 miles (3.4 kilometers) of existing Mission Road and Acequia Road ROWs. Depths of impact are anticipated to vary across the Project Area, ranging from approximately 1 to 3 feet (0.3 to 0.9 meter [m]) apart from the extension of the culvert mid-block along Mission Road, where the depth of impact is not anticipated to exceed 6 feet (1.8 m). In consultation with the COSA OHP and THC, a portion of the Project Area located between two historic-age cemeteries was targeted for the field investigation (Field Investigation Area). The total Field Investigation Area measures 2.4 ac (1 ha) along 1,777 feet (541.6 linear meters) of the Mission Road corridor, specifically between San Jose Burial Park and Mission Burial Park. Cultural resources investigations consisted of a program of archaeological trenching along the eastern and western sides of the ROW within an area proposed for decorative pavers and sidewalk/shared-used pathways. No archaeological investigations were conducted for proposed driveway improvements, utility surface adjustments, or the culvert box location within the Field Investigation Area, as this construction will be located within areas extensively disturbed by past improvements below the level of anticipated discovery. Additionally, the proposed improvements will have limited vertical impacts at this location. Archaeological trenching of the Project Area occurred between March 18 and 19, 2019, (east side of Mission Road), and again between May 4 and 6, 2020, (west side of Mission Road). Nesta Anderson and Zachary Overfield served as the Principal Investigators for the respective fieldwork dates and were assisted by archaeologists Jacob Sullivan, James Moore, Melanie Nichols, and Lily Camara. A total of 16 trenches were excavated during fieldwork in accordance with a research design initially approved by the COSA OHP on January 28, 2019 and by the THC on January 29, 2019, under Texas Antiquities Permit 8748. Amendments to the permit were approved by the COSA OHP April 28, 2020 and by the THC on May 4, 2020. The trenching investigations did not result in the documentation of any archaeological sites, nor evidence of human remains or graves within the Field Investigation Area. Based on the results of these investigations, no historic properties will be affected by the Project and no further work is recommended. All records associated with the Project will be curated at the University of Texas at San Antonio Center for Archaeological Research (UTSA-CAR)
