Cultural Resources Survey Of Pleasant Valley Road From Richfield Drive To Old Miles Road, Garland, Dallas County, Texas

This report presents the results of an intensive cultural resources survey conducted by Versar, Inc., under subcontract to Civil Associates, Inc., for Grantham and Associates, Inc., and the City of Garland Engineering Department in support of a U. S. Army Corps of Engineers Section 404 permit for the proposed widening of Pleasant Valley Road and replacement of two bridge structures over Rowlett Creek and Old Rowlett Creek in northeastern Dallas County. During the current investigation, two historic-age structures (one culvert and one bridge) were recorded in the project area. Neither of these structures is recommended eligible for inclusion in the National Register of Historic Places (NRHP) or for designation as a State Antiquities Landmark (SAL). In addition, a portion of previously recorded prehistoric archeological site 41DL203 was determined to extend into the proposed project area; however, based on the results of limited test excavations, it is recommended that the portion of the site within the area of potential effects does not contribute to the eligibility of the site as a whole for inclusion in the NRHP or designation as an SAL. No additional cultural resources evaluation or mitigation are recommended. All materials generated by this project will be permanently curated at the Texas Archeological Research Laboratory at The University of Texas at Austin

Cultural Resources Survey for the Proposed Dam No. 101 Project within the Upper Brushy Creek WCID, Williamson County, Texas

AECOM was contracted by the Upper Brushy Creek Water Control and Improvement District (UBCWCID) to conduct a cultural resources survey for the proposed Dam No. 101 project, located in Williamson County, Texas. AECOM evaluated a 189-acre area of potential effects (APE), which includes the conceptual dam footprint plus a 150-foot (ft) buffer, the inundation area, and any additional areas that could be potentially affected by key construction activities. The project is bisected by O’Conner Drive on the north side of State Highway 45 and partially overlaps the existing Dam No. 9. AECOM conducted an intensive cultural resources survey within the APE from September 16 – 20, 2019. The objectives of the survey were to inventory any archaeological and historic resources within the APE and to evaluate their eligibility for inclusion in the National Register of Historic Places (NRHP) and for designation as State Antiquities Landmarks (SALs). All work was performed in accordance with Texas Historical Commission (THC) Archeological Survey Standards for Texas. The survey was completed under Texas Antiquities Permit No. 8855 and utilized a combination of pedestrian survey methods and the systematic excavation of 78 shovel tests. No new archaeological sites were identified during the survey. However, the survey revisited four previously recorded archaeological sites, including 41WM748, 41WM750, 41WM1058, and 41WM1248. These sites are within, or are partially within, the portion of the APE located east of O’Connor Drive. Each of these sites has been impacted by erosion and natural weathering, and all the site components were found to be resting on either limestone and eroded soils surfaces, or within shallow (\u3c30 cm) soils. Due to these factors, the sites do not exhibit integrity. Due to the absence of temporally diagnostic artifacts and features, these sites are not likely to yield information important to prehistory. Based on the current investigations, we recommend that sites 41WM748, 41WM750, 41WM1058, and 41WM1248 are ineligible for listing in the NRHP and do not merit designation as SALs. In addition, the two prehistoric isolated finds (IF-1 and IF-2) identified during the survey are recommended as ineligible for NRHP listing and SAL designation. Finally, two historic-age resources, including Dam No. 9 (Resource 001) and a corral (Resource 002), were recorded during the survey and evaluated by an architectural historian. Both resources are assessed as failing to meet NRHP criteria of eligibility and are recommended as ineligible for listing in the NRHP. Right-of-entry could not be obtained for the portion of the APE on the west side of O’Connor Drive, which contains one previously recorded archaeological site (41WM1057), and one NRHP-eligible structure (ca. 1950 Agricultural Building). In 2004, the THC determined site 41WM1057 to be ineligible. Based on the current plans, no construction will take place in the APE west of O’Connor Drive. Since no significant hydrological changes would occur in this area as a result of Dam 101 construction, no impacts to these sites are anticipated and no archaeological survey is currently warranted. A field geomorphic assessment was conducted and revealed that the APE contains thin and eroded soils that formed in residuum weathered from Cretaceous limestone. Along Lake Creek, the soils consist of shallow, gravelly deposits confined to a relatively narrow flood surface. Given the residual nature and ancient age of the APE soils, the absence of deep alluvial deposits, and the high-energy flood discharge regime evidenced in creek bank profiles, the APE does not exhibit the pedologic and geomorphic conditions necessary for the deep burial and preservation of cultural deposits. It is therefore unlikely that any archaeological sites in these areas would exhibit the integrity necessary to be considered eligible for the NRHP or to merit SAL designation. No backhoe trenching is recommended for this project. Based on the results of the survey, the proposed project should have No Effect on historic properties or SALs. AECOM recommends that construction can proceed without further cultural resources investigations. However, should the dimensions of the project area change, additional archaeological and historical investigations may be warranted. If any unmarked prehistoric or historic human remains or burials are encountered at any point during the project, the area of the remains is considered a cemetery under current Texas law and all construction activities must cease immediately to avoid impacting the remains. The THC must be notified immediately by contacting the Archeology Division at (512) 463-6096. All cemeteries are protected under State law and cannot be disturbed. Further protection is provided in Section 28.03(f) of the Texas Penal Code, which provides that intentional damage or destruction inflicted on a human burial site is a state jail felony. No artifacts were collected during the survey. All correspondence, field records, and photographs generated during field investigations were prepared for permanent curation at the Texas Archeological Research Laboratory

Cultural Resources Survey for the Oncor Cogdell - Clairemont 138 kV Transmission Line Project, Kent and Scurry Counties, Texas

Oncor Electric Delivery Company, LLC (Oncor) and Brazos Electric Power Cooperative propose to construct a new, singlecircuit 138 kilovolt (kV) transmission line (Project) between the existing Oncor Cogdell substation located in Scurry County, approximately 15 miles northeast of Snyder, Texas, east of Farm-to-Market (FM) 1231, and the existing Brazos Electric Clairemont substation located in Kent County, approximately seven miles northwest of Clairemont, Texas. The proposed transmission line would be constructed with one circuit of 138 kV transmission line supported by double circuit 138 kV steel or concrete monopole structures within a 70-foot (ft) right-of-way (ROW). AECOM Technical Services, Inc. (AECOM) conducted a 100 percent pedestrian archaeological survey of the Project ROW for the portion of the Project from the Cogdell substation to the Project midpoint, which covers approximately 14.4 miles (including various potential reroutes). The survey was conducted from October 8 to 13, 2019, requiring 156 person hours in the field. The investigations reported herein were conducted in accordance with Oncor’s Generic Research Design for Archaeological Surveys of Oncor Electric Delivery Electric Transmission Line Projects in Texas (PBS&J 2008). The survey resulted in the identification and recording of a historic windmill and cistern site (41SC76), two prehistoric lithic scatters (41KT176 and 41KT177), and nine isolated finds (IFs 1 through 9). In addition, two flakes from one previously recorded site (41KT107) were found within the Project ROW. Based upon poor integrity contexts of these sites, the lack of any known associations with significant historic events and/or persons, and because the sites are not likely to yield information important to prehistory or history, each of these sites and the IFs are recommended as not eligible for listing in the National Register of Historic Places (NRHP). Furthermore, these sites do not merit designation as State Antiquities Landmarks (SALs). A single historic-age ranch complex was identified 240 feet north of the Project ROW. The ranch complex with associated agricultural outbuildings was built ca. 1930. The complex contains one single-family domestic dwelling and five outbuildings of various sizes. The resource retains some aspects of integrity, but they are unremarkable examples of a common dwelling and outbuildings. The resources do not convey association with significant historical events or a significant pattern of development. The buildings do not appear to be associated with significant persons in history and lack architectural design merit. Furthermore, the resources are not likely to yield information important to history or prehistory of the area. Therefore, the ranch complex and associated outbuildings are recommended as not eligible for listing in the NRHP. A geomorphological evaluation of the project area revealed that the Project ROW does not exhibit the pedologic and geomorphic conditions necessary for the deep burial and preservation of cultural deposits. Therefore, no geoarchaeological monitoring of transmission pole emplacement is recommended. Based on the results of the survey, the development, construction, and operation of the proposed Project should have No Effect on historic properties or SALs. It is recommended that construction can proceed without further cultural resources investigations. However, should the dimensions of the Project change, additional investigations may be required. If any unmarked prehistoric or historic human remains or burials are encountered at any point, the area of the remains is considered a cemetery under current Texas law and is protected. Section 28.03(f) of the Texas Penal Code provides that intentional damage or destruction inflicted on a human burial site is a state jail felony. If a cemetery is identified in the Project ROW, all work in the area of the discovery must cease and the THC must be notified by contacting the History Programs Division at (512) 463-5853 and the Archeology Division at (512) 463-6096. Following consultation with the THC, a treatment or avoidance plan would be developed and implemented. No artifacts were collected during the survey. All correspondence, field records, and photographs generated during field investigations will be prepared for permanent curation at Texas Archeological Research Laboratory (TARL), Austin, Texas

Cultural Resources Investigations for the Oncor Permian Basin – Culberson 138 kV Transmission Line Project, Culberson, Reeves, and Ward Counties, Texas

URS Corporation (URS) was retained by Oncor Electric Delivery Company, LLC (Oncor) to conduct an intensive cultural resources survey of the new Permian Basin - Culberson 138 kilovolt (kV) Double-Circuit Transmission Line Project (Project) right-of-way (ROW) located in Culberson, Reeves, and Ward Counties, Texas. The proposed 70-foot (ft) (21-meter [m]) wide Project ROW encompasses approximately 825 acres and traverses a total of approximately 97 miles of rural lands between the existing Oncor Permian Basin Switching Station, located approximately four miles west of Monahans, Texas in Ward County, to the existing Oncor Culberson Switching Station, located approximately 17 miles south of the Texas/New Mexico state line in Culberson County. This includes 88.7 miles of the original route, along with 8.3 miles of additional segments that were evaluated. Currently, the Project is not subject to federal funding or permitting; therefore, no review under Section 106 of the National Historic Preservation Act of 1966, as amended, is required. Should the Project subsequently become subject to federal funding or permitting, the cultural resources investigations and site evaluations reported herein will be updated and coordinated with the Texas Historical Commission (THC) as part of fulfilling any Section 106 requirements that may arise at a later date. While the majority of the Project is located on private land, an approximately 6-mile long segment of the Project ROW traverses lands owned by University Lands (UL), which is a political subdivision of the State of Texas. Consequently, this portion of the project falls within the purview of the Antiquities Code of Texas, which requires the THC to review actions that have the potential to disturb prehistoric or historic sites in the public domain. In order to comply with the Antiquities Code, Antiquities Permit No. 7848 was obtained from the THC for the UL-owned lands, and the survey methods for this portion of the Project followed the THC’s archaeological survey standards for Texas. For the remaining areas of the Project, all cultural resources investigations were carried out in conformance with the methodologies outlined in the THC-approved Generic Research Design for Archaeological Surveys of Oncor Electric Delivery Electric Transmission Line Projects in Texas (PBS&J 2008). The cultural resources survey was conducted between December 7, 2015 and May 5, 2016, and consisted of an intensive 100 percent pedestrian survey and shovel testing within the Project ROW. The survey resulted in the identification of 16 newly-recorded sites and one previously recorded site (41WR85). Site forms were completed for each of the 16 newly identified archaeological sites, and trinomials were obtained from the Texas Archeological Research Laboratory. In addition, 16 isolated finds (IFs) were identified; however no site forms were prepared for IFs. All sites within the Project ROW were located in areas of eroded and/or mixed soils, lacked diagnostic artifacts, and were found to exhibit poor integrity context due to prior disturbances. Based on these observations, the portions of these sites within the Project ROW do not meet National Register of Historic Places (NRHP) and State Antiquities Landmark (SAL) eligibility requirements. However, because each of these sites appears to extend beyond the current Project ROW boundary, they have not been evaluated in their entirety and their overall NRHP and SAL eligibility is recommended to be Undetermined. Due to a lack of research potential and integrity, all IFs are recommended as not eligible for NRHP or SAL designation. During the survey, a small bedrock cavity was observed at site 41CU835. Due to safety concerns about the surrounding ground stability, this feature could not be fully investigated. The ground immediate adjacent to the cavity, as well as the upper two feet of the cavity, did not present any indications that it was culturally related, or that the cavity extended much deeper. The entirety of the observed cavity appeared to be too narrow to have served as an effective place of interment. However, based on survey level data, the cultural utilization of this feature could not be entirely ruled out. It was recommended that construction activities avoid this cavity and that site monitoring during construction be conducted, until such time as any cultural association is definitively ruled out, or until it can be confirmed that no construction impacts to the cavity would take place. A geomorphological assessment revealed that selected areas within the Project ROW potentially exhibit the necessary pedologic and geomorphic conditions for the deep burial and preservation of cultural deposits. These areas represent a combined total of 15.5 linear miles (25 kilometers) of Project ROW. In accordance with the Generic Research Design, monitoring was recommended for any transmission pole excavations in the areas that were assessed as exhibiting high geoarchaeological potential. An interim draft report of the foregoing recommendations was submitted to the THC on April 27, 2017. On May 26, 2017, the THC concurred with all interim report recommendations. During preparations for the monitoring effort, URS was notified by Oncor that a majority of the Project had already been constructed, including those areas recommended for monitoring. The only location that had not yet been constructed was the bedrock cavity at site 41CU835. On May 24, 2017, a meeting between Oncor, URS, and the THC resulted in an agreement that monitoring should be undertaken during construction activities near the bedrock cavity at site 41CU835. In addition, it was agreed that spot-checks would be performed within a subset of the previously constructed structures within high geoarchaeological probability areas, including portions of the Project owned by UL. Following completion of these tasks, it was agreed that a comprehensive revised draft report of investigations and findings (current report) would be submitted to the THC for review and project closure. Subsequent investigations at the bedrock cavity at 41CU835 were carried out from July 10-11, 2017. During the site visit, it was established that the cavity is located approximately 30 m to the southeast of the proposed location of monopole structure No. 56/3. Following additional inspections, it was possible to rule out any prehistoric use of this natural feature. The immediate area around the cavity was taped off for safety reasons so that other related construction activities would not adversely impact the cavity or surrounding area. On July 11, 2017, monitoring was carried out for the excavation of monopole structure no. 56/3. Soil stratigraphy was recorded for the total depth of the excavation, which was 20 ft. No cultural materials were identified From August 12-13, 2017, URS archaeologists performed spot-checks for 99 monopoles, including 53 structures within the Project ROW extending approximately 10 kilometers (km) west of the Pecos River in Reeves County; 22 structures within the Project ROW extending approximately 4 km east of the Pecos River in Ward County; and 24 structures within the Project ROW extending approximately 4.5 km across Monument Draw within UL in Ward County. Spot-checking included visual inspection and photo documentation of disturbances, as well as ground surface inspection to identify cultural resources. The Project ROW around each monopole exhibited construction related disturbances from equipment access roads and from drilling operations. No evidence was found that indicated any deeply buried cultural resource sites were impacted from auguring. Within the intervening areas between monopoles, however, a total of two previously unrecorded, low-density historic surface scatters (41RV128 and 41RV129) and three new IFs (H-07, H08, and P-28) were identified and recorded. Both sites were found to exhibit poor integrity due to prior disturbances, and low research potential due to minimal information potential. The portions of these sites within the Project ROW were not found to meet NRHP and SAL eligibility requirements. However, because each of these sites appears to extend beyond of the current Project ROW boundary, they have not been evaluated in their entirety and their overall NRHP and SAL eligibility is recommended to be Undetermined. The three new IFs are recommended as not eligible for NRHP or SAL designation. Based on the final results of the survey, monitoring, and spot-checking investigations, no cultural resources sites eligible for listing in the NRHP or that merit SAL designation within the Project ROW will be affected by the Project, and it is recommended that the project be allowed to proceed. Should the dimensions of the Project ROW change, additional archaeological investigations may be warranted. Should any unmarked prehistoric or historic human remains or burials be encountered at any point during the project, the area of the remains is considered a cemetery under current Texas law. All cemeteries are protected under State law and cannot be disturbed. Section 28.03(f) of the Texas Penal Code provides that intentional damage or destruction inflicted on a human burial site is a state jail felony. If a cemetery is identified in the Project ROW, all work in the immediate area of the discovery must cease and the THC must be notified by contacting the History Programs Division at (512) 463-5853 and the Archeology Division at (512) 463-6096. Following consultation with the THC, a treatment or avoidance plan would be developed and implemented. No artifacts were collected during the survey. Pursuant to 13 TAC 26.17, correspondence, field records, and photographs generated during field investigations have been prepared for permanent curation at the Texas Archeological Research Laboratory, Austin, Texas

Pollination service delivery is complex: Urban garden crop yields are best explained by local canopy cover and garden scale plant species richness

Pollination is an important ecosystem service to agriculture, however, the factors influencing pollination in urban food gardens are poorly understood.
 We investigated how features within urban environments, including floral resources and canopy cover, impacted (a) flower visitation and seed production of a model plant (Brassica rapa) and (b) total yields of produce from urban gardens in Sydney, Australia.
 Floral visitation to model plants was dominated by a few common species, with honeybees responsible for 53.4% of visitation and native stingless bees and two hoverfly species accounting for another 37.1% of visitors; 28 other species were collectively responsible for less than 10% of visitation.
 While insect pollinators were abundant, the relationship between floral visitation and model plant reproductive output was weak and not always positive. The pollination success of model plants was only marginally impacted by environmental features, while pollinator visitation had a small negative impact. 
 However, total crop yields across urban gardens were strongly influenced by local canopy cover and garden scale plant species richness.
 Synthesis and applications. The factors influencing pollination service delivery to urban gardens are complex; pollinator visitation, richness and/or floral resource availability may not always reflect positive, plant reproductive outcomes. Yields of garden crops, whether pollinator dependent or not, were more strongly influenced by surrounding environmental variables, including broad scale measures of canopy cover and local plant diversity, than pollination-related metrics. This implies policies to support pollinator richness will likely differ to those supporting crop yields in urban gardens and will require assessment and management of external environmental factors

Tracking (poly)phenol components from raspberries in ileal fluid

The (poly)phenols in ileal fluid after ingestion of raspberries were analysed by targeted and non-targeted LC-MSn approaches. Targeted approaches identified major anthocyanin and ellagitannin components at varying recoveries and with considerable inter-individual variation. Non-targeted LC-MSn analysis using an Orbitrap mass spectrometer gave exact mass MS data which was sifted using a software program to select peaks that changed significantly after supplementation. This method confirmed the recovery of the targeted components but also identified novel raspberry-specific metabolites. Some components (including ellagitannin and previously unidentified proanthocyanidin derivatives) may have arisen from raspberry seeds that survived intact in ileal samples. Other components include potential breakdown products of anthocyanins, unidentified components and phenolic metabolites formed in either the gut epithelia or after absorption into the circulatory system and efflux back into the gut lumen. The possible physiological roles of the ileal metabolites in the large bowel are discussed
