An Intensive Pedestrian Survey For A 143-Acre Development And Outfall Project Near Pederson Road And Williow Fork In Waller And Fort Bend Counties, Texas

HRA Gray & Pape, LLC., of Houston, Texas, conducted an intensive pedestrian cultural resources survey of approximately 58 hectares (143 acres) of property proposed for development as well as 2 outfalls in Waller and Fort Bend Counties, Texas. The United States Army Corps of Engineers has been identified as the Lead Agency for this Project. The goals of the survey were to determine if the Project would affect any previously identified archaeological sites as defined by Section 106 of the National Historic Preservation Act of 1966, as amended (36 CFR 800), and to establish whether or not previously unidentified buried archaeological resources were located within the Project’s Area of Potential Effects. The procedures to be followed by the United States Army Corps of Engineers to fulfill the requirements set forth in the National Historic Preservation Act, other applicable historic preservation laws, and Presidential directives as they relate to the regulatory program of the United States Army Corps of Engineers (33 CFR Parts 320-334) are articulated in the Regulatory Program of the United States Army Corps of Engineers, Part 325 - Processing of Department of the Army Permits, Appendix C - Procedures for the Protection of Historic Properties. All fieldwork and reporting activities were completed with reference to state (the Antiquities Code of Texas) and federal (National Historic Preservation Act) guidelines. Survey and site identification followed Texas Antiquities Code standards. The Project area includes private property; therefore, a Texas Antiquities Permit was not required. The property boundary for this Project is approximately 58 hectares (143 acres) and includes 2 outfalls. This defines the Area of Potential Effects. Field investigation consisted of visual inspection, subsurface shovel testing and supplemental deep testing. Subsurface investigation resulted in the excavation of 130 shovel tests and 9 manual bucket auger tests. All were negative for archaeological deposits and no intact structures of historic-age were observed within or immediately adjacent to the Area of Potential Effects. Based on the negative results of the archaeological investigation, HRA Gray & Pape, LLC. recommends no further archaeological work for this Project

A Cultural Resources Survey Of Texas Eastern Transmission LPS Phase 1 Pipeline Anomaly Repairs On The PETR To Tivo Segment Of Line 16 In Refugio And Aransas Counties, Texas

On behalf of Texas Eastern Transmission, LP and Edge Engineering and Science, LLC., HRA Gray & Pape, LLC, of Houston, Texas, has completed a 100% pedestrian cultural resources survey and limited shovel testing of an estimated 4.5 kilometers (2.8 miles) of linear area in Refugio and Aransas Counties, Texas. Texas Eastern has identified several locations along the PETR to TIVO Segment of Line 16 that require replacement of aging pipe. One of the areas requiring maintenance work is identified as “Phase 1”, for which the archaeological survey was completed in May of 2015. The Lead Federal Agency has been identified as the United States Army Corps of Engineers, Galveston District. Thus the goals of the survey were to determine if land altering activities required to complete this project would affect any previously identified historic properties as defined by Section 106 of the National Historic Preservation Act of 1966, as amended (36 CFR 800), and to establish whether or not previously unidentified cultural resources were located within the project’s Area of Potential Effects (Advisory Council for Historic Preservation 2004). Initial investigation consisted of a background literature and site files search to identify the presence of recorded sites in close proximity to the project area. No previous archaeological linear or area surveys have taken place within the project area. No previously recorded archaeological sites were identified within the project area. The project is located on private property, thus an Antiquities Code of Texas Permit was not required prior to performing fieldwork. All work was conducted following accepted standards set forth by the Texas Historical Commission and the Council of Texas Archeologists. All 4.5 kilometers (2.8 miles) of the proposed “Phase 1” pipeline replacement area have been investigated. Fieldwork for the Phase I workspaces was completed in a single mobilization that took place from May 18 to May 22, 2015, and required 96 person hours to complete. Field investigation was conducted entirely on privately owned properties and consisted of walkover and shovel testing within the project area. During this investigation no cultural resources were identified or confirmed within the project’s Area of Potential Effects. Based on the negative findings of the survey, HRA Gray & Pape, LLC. recommends that no further cultural resources work be required for the “Phase 1” portion of the project and that the project be allowed to proceed as planned within the surveyed areas. Additional project phases are in the process of being surveyed. Results of those efforts will be submitted when completed

Intensive Cultural Resources Survey of the Proposed 54.5-acre Country Club Road Tract, Conroe, Montgomery County, Texas

Horizon Environmental Services, Inc. (Horizon) was selected by Forestar Real Estate Group, Inc. to conduct a cultural resources inventory and assessment for the proposed 22.1- hectare (54.5-acre) Country Club Road tract in Conroe, Montgomery County, Texas. The proposed development tract is located in a largely undeveloped forested area south of the Conroe Country Club, east of Old Country Club Road, and north of Farm-to-Market Road (FM) 2854 in western Conroe. For purposes of the cultural resources survey, the project area is assumed to consist of the entire 22.1-hectare (54.5-acre) tract. The proposed undertaking would be sponsored by a private real estate developer on privately owned land. However, the project may require the use of Nationwide Permits (NWP) issued by the US Army Corps of Engineers (USACE), Galveston District, to permit construction within any “waters of the US” that may be present on the property under Section 404 of the Clean Water Act. As NWPs are federal permits, any portion of the overall project area that falls within the federal permit area would fall under the jurisdiction of Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended. As the proposed project represents a publicly sponsored undertaking, the project sponsor is required to provide the applicable federal agencies and the Texas Historical Commission (THC), which serves as the State Historic Preservation Office (SHPO) for the state of Texas, with an opportunity to review and comment on the project’s potential to adversely affect historic properties listed on or considered eligible for listing on the National Register of Historic Places (NRHP). At this time, no other federal or state jurisdiction has been identified for the project. From July 13 to 16, 2020, Horizon archeologists Charles E. Bludau, Jr. and Luis Gonzalez conducted an intensive cultural resources survey of the project area. Jeffrey D. Owens served as Principal Investigator. The purpose of the survey was to locate any significant cultural resources that potentially would be impacted by the proposed undertaking. Horizon’s archeologists traversed the tract and thoroughly inspected the modern ground surface for aboriginal and historic-age cultural resources. The project area consists of a large tract of undeveloped forestland characterized by dense hardwoods with a moderately dense understory of shrubs, grasses, forbs, brambles, vines, and various grasses. Disturbances from prior clearance of a linear dirt road corridor providing access to the tract from Old Country Club Road to the west, a transmission line corridor along the southern margin of the project area, and clearing of several all-terrain vehicle (ATV) tracks within the project area were observed, though the project area appears to be largely intact as a whole. appears to be largely intact as a whole. In addition to pedestrian walkover, the Texas State Minimum Archeological Survey Standards (TSMASS) require a minimum of two shovel tests per 0.4 hectare (1.0 acre) for projects measuring 10.1 hectares (25.0 acres) or less in size plus one additional shovel test per 2.0 hectares (5.0 acres) beyond the initial 10.1 hectares (25.0 acres). As such, a minimum of 56 shovel tests were required within the current 22.1-hectare (54.5-acre) project area. Horizon excavated a total of 65 shovel tests, thereby exceeding the TSMASS for a project area of this size. Shovel tests typically revealed gravelly fine sandy loam to sandy loam sediments transitioning to sandy clay and clay subsoils at depths ranging from 15 to 60.0 centimeters (5.9 to 23.6 inches) below surface, though this transition typically occurred in the range of 25.0 to 35.0 centimeters (9.8 to 13.8 inches) below surface. It is Horizon’s opinion that shovel testing was capable of fully penetrating sediments with the potential to contain subsurface archeological deposits. Several modern trash piles were observed throughout the project area and objects observed included plastic soda bottles, oil containers and filters, metal barrels, a bed mattress, a hot tub, roofing shingles, a steel traffic signpost, plastic buckets, and a rusted metal barbeque pit. No cultural resources of prehistoric or historic age were observed on the modern ground surface or within any of the shovel tests excavated within the project area during the survey. Based on the results of the survey-level investigations documented in this report, no potentially significant cultural resources would be affected by the proposed undertaking. In accordance with 36 CFR 800.4, Horizon has made a reasonable and good-faith effort to identify historic properties within the project area. No cultural resources were identified within the project area that meet the criteria for inclusion in the NRHP under 36 CFR 60.4. Horizon recommends a finding of “no historic properties affected,” and no further archeological work is recommended in connection with the proposed undertaking. However, human burials, both prehistoric and historic, are protected under the Texas Health and Safety Code. In the event that any human remains or burial objects are inadvertently discovered at any point during construction, use, or ongoing maintenance in the project area, even in previously surveyed areas, all work should cease immediately in the vicinity of the inadvertent discovery, and the THC should be notified immediately

Intensive Cultural Resources Survey of the 380.6-Acre Stockdick School Road Tract, Katy, Harris County, Texas

Horizon Environmental Services, Inc. (Horizon) was selected by Berg-Oliver Associates, Inc. (BOA) on behalf of the Harris County Flood Control District (HCFCD) to conduct a cultural resources inventory and assessment for the proposed Stockdick School Road Project in Katy, Harris County, Texas (HCFCD Project No. U501-07-00-E001). The proposed undertaking would consist of constructing various storm water detention ponds and other drainage improvements within a non-contiguous 154.0-hectare (380.6-acre) tract located off either side of Grand Avenue Parkway (State Highway [SH] 99) in Katy, Harris County, Texas. The tract is bounded on the north by Stockdick School Road, on the west by Peek Road, on the south by Clay Road, and on the east by the Vineyard Meadow Tuscany residential subdivision. Mayde Creek flows southeastward through the tract. For purposes of the cultural resources survey, the project area is assumed to consist of the entire 154.0-hectare (380.6-acre) tract. The proposed undertaking is being sponsored by HCFCD, a political subdivision of the state of Texas; as such, the project would fall under the jurisdiction of the Antiquities Code of Texas. In addition, the project would require the use of federal permits issued by the US Army Corps of Engineers (USACE), Galveston District, under Section 404 of the Clean Water Act (CWA). As such, those portions of the overall project area that fall within the federal permit area would also fall under the jurisdiction of Section 106 of the National Historic Preservation Act (NHPA). As the proposed project represents a publicly sponsored undertaking, the project sponsor is required to provide the applicable federal agencies, in this case the USACE, and the Texas Historical Commission (THC), which serves as the State Historic Preservation Office (SHPO) for the state of Texas, with an opportunity to review and comment on the project’s potential to adversely affect historic properties listed on or considered eligible for listing on the National Register of Historic Places (NRHP) under the NHPA and/or for designation as State Antiquities Landmarks (SAL) under the Antiquities Code of Texas. Between April 30 and May 5, 2020, Horizon archeologists Charles E. Bludau, Jr. and Luis Gonzalez conducted an intensive cultural resources survey of the project area. Jeffrey D. Owens acted as Principal Investigator, and the survey was conducted under Texas Antiquities Permit No. 9409. The purpose of the survey was to locate any significant cultural resources that potentially would be impacted by the proposed undertaking. Horizon’s archeologists traversed the project area and thoroughly inspected the modern ground surface for aboriginal and historic-age cultural resources. The project area consists of a vast tract that is roughly bisected by Mayde Creek, which flows southeastward through the approximate middle of the tract. Areas adjacent to the creek were largely undeveloped and covered in dense hardwood forests with a thick understory of shrubs, grasses, forbs, brambles, vines, and various grasses. Vegetation in the more open areas consisted of dense pasture grasses with isolated copses of hardwood trees. Whereas most of the project area is undeveloped and appears to be largely intact, various disturbances were observed. An Enterprise Crude Pipeline, LLC pipeline corridor passes northeast to southwest through the north-central portion of the project area; a Kinder Morgan Texas Pipeline, LLC pipeline corridor passes northeast to southwest through the central portion of the project area; and a transmission line passes northwest to southeast through the center of the project area. In the northwestern corner of the project area, immediately south of Stockdick School Road and east of Clay Road, a large section of land has been cleared and a number of underground utility lines have been installed. In the southwestern corner of the project area, north of Clay Road and east of Peek Road, a wide, contoured drainage channel has been constructed. Finally, Grand Avenue Parkway (SH 99) passes between the two sections of the project area located on either side of the highway. Visibility of the modern ground surface ranged from poor (\u3c20%) in more heavily vegetated areas to excellent (80 to 100%) in cleared areas. In addition to pedestrian walkover, the Texas State Minimum Archeological Survey Standards (TSMASS) call for excavation of a minimum of two shovel tests per 0.4 hectare (1.0 acre) for projects measuring 10.1 hectares (25.0 acres) or less in size plus one additional shovel test per 2.0 hectares (5.0 acres) above 10.1 hectares (25.0 acres). As such, a minimum of 121 shovel tests would be required within the 154.0-hectare (380.6-acre) project area. Horizon excavated a total of 164 shovel tests, thereby exceeding the TSMASS for a project area of this size. Shovel tests typically revealed sandy clay loam to sandy loam sediments overlying sandy clay. Mottling and iron staining were ubiquitous in shovel tests, suggesting that large portions of the project area are likely saturated on a seasonal or perennial basis. It is Horizon’s opinion that shovel testing was capable of fully penetrating sediments with the potential to contain subsurface archeological deposits. No cultural resources of prehistoric or historic age were recorded within the project area during the survey. A modern church or some other type of large community center is present in the northern portion of the project area off the southern side of Stockdick School Road. This structure was built at some time between 1973 and 1981; as such, the structure is not of historic age. Based on the results of the survey-level investigations documented in this report, no potentially significant cultural resources would be affected by the proposed undertaking. In accordance with 36 CFR 800.4, Horizon has made a reasonable and good-faith effort to identify historic properties within the project area. No cultural resources were identified within the project area that meet the criteria for designation as SALs according to 13 TAC 26 or for inclusion in the NRHP under 36 CFR 60.4. Horizon recommends a finding of “no historic properties affected,” and no further archeological work is recommended in connection with the proposed undertaking. However, human burials, both prehistoric and historic, are protected under the Texas Health and Safety Code. In the event that any human remains or burial objects are inadvertently discovered at any point during construction, use, or ongoing maintenance in the project area, even in previously surveyed areas, all work should cease immediately in the vicinity of the inadvertent discovery, and the THC should be notified immediately. Following completion of the project, project records will be permanently curated at the Texas Archeological Research Laboratory (TARL)

Intensive Cultural Resources Survey of the Proposed 829.9-Acre Schiel Storm Water Detention Basin Project, Harris County, Texas

Horizon Environmental Services, Inc. (Horizon) was selected by Berg-Oliver Associates, Inc. (BOA) on behalf of the Harris County Flood Control District (HCFCD) to conduct a cultural resources inventory and assessment for the proposed Schiel Storm Water Detention Basin Project in Harris County, Texas (HCFCD Project No. L500-09-00-E003). The proposed undertaking would consist of constructing an extensive system of storm water detention basins and other drainage control measures within an approximately 335.8-hectare (829.9-acre) tract located near Hockley in northwestern Harris County. The project area generally flanks Little Cypress Creek and is bounded roughly on the west by Becker Road, on the south by Schiel Road, and on the east by Mason Road. For purposes of the cultural resources survey, the project area was assumed to consist of the entire 335.8-hectare (829.9-acre) tract. The proposed undertaking is being sponsored by HCFCD, a political subdivision of the state of Texas; as such, the project would fall under the jurisdiction of the Antiquities Code of Texas. In addition, the project would require the use of federal permits issued by the US Army Corps of Engineers (USACE), Galveston District, under Section 404 of the Clean Water Act (CWA). As such, those portions of the overall project area that fall within the federal permit area would also fall under the jurisdiction of Section 106 of the National Historic Preservation Act (NHPA). As the proposed project represents a publicly sponsored undertaking, the project sponsor is required to provide the applicable regulatory agencies with an opportunity to review and comment on the project’s potential to adversely affect historic properties listed on or considered eligible for listing on the National Register of Historic Places (NRHP) under the NHPA and/or for designation as State Antiquities Landmarks (SAL) under the Antiquities Code of Texas, as appropriate. Between February 2019 and April 2020, Horizon archeologists Charles E. Bludau, Jr., Luis Gonzalez, and Amanda Kleopfer conducted an intensive cultural resources survey of the project area. Jeffrey D. Owens acted as Principal Investigator, and the survey was conducted under Texas Antiquities Permit No. 8700. The purpose of the survey was to locate any significant cultural resources that potentially would be impacted by the proposed undertaking. Horizon’s archeologists traversed the tract and thoroughly inspected the modern ground surface for aboriginal and historic-age cultural resources. The project area consists of a vast tract that largely follows the channel of Little Cypress Creek. Areas adjacent to the creek were largely undeveloped and covered in moderately dense hardwood forests with a dense understory of shrubs, grasses, forbs, brambles, vines, and various grasses. Portions of the project area consisted of extensive cleared fields, some of which appeared to have been formerly cultivated, and most of which were in use as pastureland. Vegetation in the more open areas consisted of dense pasture grasses with isolated copses of hardwood trees. Whereas most of the project area is undeveloped and appears to be largely intact, various disturbances were observed. Several roadways traverse the project area, including State Highway (SH) 99, Bauer Road, and Mason Road, and a linear pipeline corridor passes northeast to southwest through the northern portion of the project area. An extensive sand-mining pit located immediately west of SH 99 has effectively destroyed approximately 35.8 hectares (88.5 acres) of the project area. Two large, contoured drainage channels have been constructed in the western portion of the project area that have disturbed a collective area of approximately 13.2 hectares (32.5 acres) of the project area. These drainage channels appear to be associated with a small residential subdivision located to the west of the project area off the eastern side of Becker Road that was under construction at the time of the survey. Visibility of the modern ground surface ranged from poor (\u3c20%) in more heavily vegetated areas to excellent (80 to 100%) in cleared areas. The cultural resources survey was conducted prior to the implementation of revised archeological survey guidelines by the Council of Texas Archeologists (CTA) and Texas Historical Commission (THC) on April 17, 2020; as such, the prior guidelines of 2014 were utilized for the project. Under these guidelines, the Texas State Minimum Archeological Survey Standards (TSMASS) require a minimum of one shovel test per 1.2 hectares (3.0 acres) for project areas measuring 40.9 hectares (101.0 acres) or more in size. As such, a minimum of 211 shovel tests would be required within the 335.8-hectare (829.9-acre) project area. Horizon excavated a total of 633 shovel tests, thereby exceeding the TSMASS for a project area of this size. Shovel tests typically revealed sandy clay loam to sandy loam sediments overlying sandy clay. Mottling and iron staining was ubiquitous in shovel tests, suggesting that large portions of the project area are likely saturated on a seasonal or perennial basis. Extensive areas of standing water were observed over the course of the year during which the cultural resources survey was conducted. The majority of the project area is characterized by fluviomarine terraces created during the Late Pliocene and Early Pleistocene epochs, though the terraces of Little Cypress Creek are of Holocene age. While not all shovel tests contained iron concretions, they were encountered in enough of the shovel tests to suggest that shovel testing was capable of penetrating Holoceneage sediments with the potential to contain subsurface archeological resources. It is Horizon’s opinion that shovel testing was capable of fully penetrating sediments with the potential to contain archeological deposits; as such, mechanical deep testing was not utilized. One newly recorded archeological site, 41HR1241, was documented within the project area during the survey. This site consists of the remains of the 20th-century farm of Alfred William (A.W.) and Mary Kathryn Petry. Historical maps indicate the farm was in operation as early as 1920, and it appears to have been abandoned by the 1980s. Formerly, the farm was composed of a domicile, at least one large outbuilding, and several smaller outbuildings, but all of the historicage structures have been demolished. Numerous large bulldozer push piles were observed on the site that contained concrete rubble and other construction debris, and it is likely these push piles are all that remains of the historic-age buildings that once stood on the site. Currently, all that remains of the Petry farm are several abandoned vehicles, a concrete well covered over with an overturned wheelbarrow, and a low-density surface and shallow subsurface scatter of domestic debris, including clear and brown glass shards, metal wire fragments, a railroad spike, a spark plug, construction debris (primarily concrete chunks), aluminum beer cans, glass beer bottles, and some polyvinyl chloride (PVC) piping. Aside from the beer bottles and cans and the PVC piping, which are clearly of modern age and date from the end of the lifecycle of the farm, most of the cultural materials observed on the farm are only generally diagnostic of the 20th century. The only standing structure remaining on the site is a modern metal garage. Site 41HR1241 has been largely destroyed, and very little remains of the Petry farm. Based on the lack of standing historic-age buildings or intact cultural features, the ephemeral character of the surficial and shallow subsurface archeological deposits, and the absence of any known historical distinction of the members of the Petry family or association of the farm with events or trends of historical importance, site 41HR1241 is recommended as ineligible for inclusion in the NRHP and for designation as an SAL. Based on the results of the survey-level investigations documented in this report, no potentially significant cultural resources would be affected by the proposed undertaking. In accordance with 36 CFR 800.4, Horizon has made a reasonable and good-faith effort to identify historic properties within the project area. No cultural resources were identified within the project area that meet the criteria for designation as SALs according to 13 TAC 26 or for inclusion in the NRHP under 36 CFR 60.4. Horizon recommends a finding of “no historic properties affected,” and no further archeological work is recommended in connection with the proposed undertaking. However, human burials, both prehistoric and historic, are protected under the Texas Health and Safety Code. In the event that any human remains or burial objects are inadvertently discovered at any point during construction, use, or ongoing maintenance in the project area, even in previously surveyed areas, all work should cease immediately in the vicinity of the inadvertent discovery, and the THC should be notified immediately. Following completion of the project, project records will be prepared for permanent curation at the Texas Archeological Research Laboratory (TARL)

Intensive Cultural Resources Survey of the Proposed Galveston County Project, Texas City, Galveston County, Texas

On behalf of Florida Gas Transmission Company, LLC (FGT), EDGE Engineering and Science, LLC (EDGE) has selected Horizon Environmental Services, Inc. (Horizon) to conduct a cultural resources survey and assessment for the proposed Galveston County Project. The project includes a proposed pipeline that will allow the delivery of natural gas to a new delivery point off the FGT mainline. The facilities to be installed include approximately 4.0 kilometers ([km] 2.5 miles) of 30.5-centimeter ([cm]12.0-inch) and 50.8-cm (20.0-inch) lateral piping as well as a measurement and regulation (M&R) station located at the southwest end of the new pipeline, referred to as the Attwater-Topaz M&R station. This portion of the proposed project is located approximately 2.9 km (1.8 miles) northwest of Texas City and crosses State Highway (SH) 146 in Galveston County, Texas. As part of the Galveston County Project, FGT will also be uprating a unit at their existing CS 4 compressor station in Matagorda County, Texas to maintain a sufficient delivery pressure to the proposed Attwater-Topaz M&R station. In accordance with Section 7(b) of the Natural Gas Act, the project requires Prior Notice authorization to the Federal Energy Regulatory Commission (FERC), which will serve as the lead federal agency for the undertaking. Because the undertaking is regulated by FERC, the undertaking falls under the regulations of Section 106 of the National Historic Preservation Act (NHPA) of 1966, as amended. The Antiquities Code of Texas (ACT) governs proposed undertakings by political subdivisions of the State of Texas and/or projects located on publicly owned lands. Approximately 11.3 hectares (27.8 acres) of the project area are owned by the Gulf Coast Water Authority (GCWA). Since the GCWA is a public entity, this portion of the project falls under the jurisdiction of the ACT. Survey of the GCWA property was carried out under Antiquities Permit No. 9449. Less than 0.1 hectare (0.2 acres) of additional temporary workspace (ATWS) falls within the State Highway (SH) 146 ROW, which is controlled by the Texas Department of Transportation (TxDOT). Since TxDOT is a State agency, survey of this area would also require an Antiquities Permit. However, this area has already been disturbed from road construction and underground utilities. Horizon therefore recommends no additional survey or shovel testing in this ATWS. Horizon sent a letter with this recommendation to the Texas Historical Commission (THC) on June 30, 2020. Originally, FGT did not define the actual limits of the proposed right-of-way (ROW) for the project. Rather, they elected to wait until after the environmental assessments on larger overall parcels were complete in order to select a route with the least amount of environmental impacts. As such, the cultural resources survey initially consisted of 100% survey of the entire 203.2 hectares (502.0 acres) that comprise the parcels traversed by the proposed pipeline. After FGT selected a proposed route, Horizon archeologists conducted additional fieldwork to ensure adequate survey coverage within the proposed ROW. From May 12 to 15, and June 17, 2020, Horizon archeologists Charles E. Bludau, Jr. and Luis Gonzales performed an intensive cultural resources survey of the project area to locate any cultural resources that would potentially be impacted by the proposed undertaking. Horizon’s archeologists traversed the project area on foot and thoroughly inspected the modern ground surface for aboriginal and historic-age cultural resources. The project area consists of an extensive, largely featureless coastal flat. An existing FGT pipeline corridor passes from northeast to southwest through the northern portion of the project area. In addition to pedestrian walkover, the recently revised 2020 Texas State Minimum Archeological Survey Standards (TSMASS) require at least 50 shovel tests for the first 10.1 hectares (25.0 acres) of a project plus at least one shovel test for every 2.0 hectares (5.0 acres) over the original 10.1 hectares (25.0 acres). This equates to a minimum of 145 shovel tests within the original 203.2-hectare (502.0-acre) project area. Horizon excavated156 shovel tests within this area, thereby exceeding the TSMASS for a project area of this size. The TSMASS require a minimum of 16 shovel tests per mile for projects measuring 30.0 m (98.4 feet) or less in width; this equates to a minimum of 40 shovel tests within the proposed ROW. Horizon exceeded this minimum by excavating 46 shovel tests within the proposed ROW. Shovel testing typically revealed shallow deposits of hydric, dark gray clay extending from the modern ground surface to depths ranging from 5.0 to 60.0 cm (2.0 to 23.6 inches) below surface, though most shovel tests were terminated at depths of 30.0 to 50.0 cm (11.8 to 19.7 inches) below surface. Shovel testing was capable of penetrating Holocene-age soils with the potential to contain subsurface archeological resources. No archeological sites or historic-aged structures were recorded within the project area during the survey. A modern cattle corral, constructed with modern lumber, is present in the northeast corner of the project area, south of Skyline Drive. The corral does not appear on any historical topographic maps. It is first visible in a 1981 aerial image, which indicates the corral is not of historic age. Based on the results of the survey-level investigations documented in this report, no significant cultural resources would be affected by the proposed undertaking. In accordance with 36 CFR 800.4, Horizon has made a reasonable and good faith effort to identify historic properties within the project area. No cultural resources were identified within the project area that meet the criteria for inclusion in the National Register of Historic Places (NRHP) under 36 CFR 60.4. Horizon recommends a finding of “no historic properties affected,” and no further archeological work is recommended in connection with the proposed undertaking. However, human burials, both prehistoric and historic, are protected under the Texas Health and Safety Code. In the event that any human remains or burial objects are inadvertently discovered at any point during construction, use, or ongoing maintenance in the project area, even in previously surveyed areas, all work should cease immediately in the vicinity of the inadvertent discovery, and the THC should be notified immediately
