LSD surveyed approximately 84 acres of SRP-owned land to identify, document, and evaluate cultural resources for their National Register of Historic Places (NRHP) eligibility; however, this project is not a Federal undertaking and no consultation under Section 106 of the National Historic Preservation Act is required at this time. Recommendations for the treatment or avoidance of sites are offered for future management considerations. The survey resulted in the discovery of 1 previously recorded site, 4 newly recorded sites, and 9 lOs. The lOs are recommended not eligible for inclusion in the NRHP; recordation during survey has fully exhausted their research potential and no avoidance is required. Since the completion of this report two addendums have been done. They are entitled Salado Preserve Addendum I: Cultural Resources Monitoring of Seismic Testing within the Salado Preserve South of St. Johns, Apache County, Arizona (Fahrni, Foster 2011) and Salado Preserve Addendum II: Cultural Resources Survey of 3.5 Miles of Fence Line within the Salado Preserve, South of St. Johns, Apache County, Arizona (Fahrni, Foster 2011).

Salt River Project Agricultural Improvement and Power District (SRP) requested that Logan Simpson Design Inc. (LSD) perform a Class III cultural resources survey of 4.7 acres for a proposed 12 kV distribution line south of Queen Valley, Pinal County, Arizona. The project area, which is located on State Trust land under the jurisdiction of the Arizona State Land Department (ASLD) north of US 60 near Hewitt Road. The cultural resources survey was requested by SRP in support of ASLD right-of-way (ROW) application number 18-112296. The project will involve the installation of a 12 kV overhead distribution line in a 10-ft-wide by 2.75-mile-long corridor to be operated and maintained by SRP. Because the project is located on land under the jurisdiction of ASLD, the cultural resources survey was completed in compliance with the requirements set forth in ARS § 41-861 et seq., the Arizona State Historic Preservation Act. This is a revised report.

This report presents the results of a Class III non-collection cultural resource survey of approximately 640 acres of land for the Salt River Project (SRP) Coronado Generating Station (CGS) Land Addition II project near St. Johns, Apache County, Arizona (Figures 1 and 2). Entranco conducted the survey at the request of SRP as Bid No. II 98999 IDC prior to the proposed land acquisition to determine whether significant cultural resources exist within the project area. For purposes of this investigation, the term “cultural resources” refers to prehistoric or historic archaeological sites or objects, and potentially significant historic buildings or structures. The project area consists of Arizona State Trust Land, administered by the Arizona State Land Department (ASLD). An evaluation of Traditional Cultural Properties was not included as a part of this investigation. Original report was revised in October 2002.

This document presents a data recovery plan to mitigate adverse effects to cultural resources within AZ U:10:123 (ASM) that will result from construction of the proposed Red Mountain Freeway (RMF), Gilbert Road to Higley Road segment in Mesa, Maricopa County, Arizona (Figure 1). The data recovery will be completed by Entranco, and was requested by the Arizona Department of Transportation (ADOT). The project is to be completed as part of the final design contract between ADOT and Entranco for the Gilbert Road to Higley Road segment of RMF.

This document consists of a research design and work plan for archaeological testing at four cultural resource sites within the proposed Red Mountain Freeway (RMF), Gilbert Road to Higley Road segment in Mesa, Maricopa County, Arizona. Testing will be conducted to evaluate the eligibility of AZ U:9:226 (ASM), AZ U:10:117 (ASM), AZ U:10:122 (ASM), and AZ U:10:123 (ASM) for inclusion in the National Register of Historic Places (NRHP) prior to proposed construction of the RMF. Nine cultural resource sites are intersected by this segment of the proposed RMF corridor. The Gilbert Road to Higley Road segment of the RMF will cross privately owned land, Arizona State Trust land administered by the Arizona State Land Department, and land administered by the Roosevelt Water Control District. Additional new right-of-way (R/W) is being obtained by ADOT from private landowners to complete this project. At the request of the ADOT Historic Preservation Coordinator (HPC), one cultural resource site that is located east of Higley Road, outside the Gilbert Road to Higley Road segment of the RMF, will also be included in the cultural resource investigations under this work plan. This site is located within a land parcel owned by the Maricopa County Flood Control District. For purposes of this work plan, however, the portion of the RMF containing the four cultural resource sites that are to be tested by Entrance is hereafter referred to as the project corridor.

Entranco conducted archaeological testing at AZ U:10:122 (ASM) and AZ U:10:123 (ASM) during October and November 2000. The testing was done to assess the eligibility of the two sites for inclusion in the National Register of Historic Places (NRHP). The project was completed at the request of the Arizona Department of Transportation prior to the proposed construction of the Red Mountain Freeway Gilbert Road to Higley Road segment, which will impact both AZ U:10:122 (ASM) and AZ U:10:123 (ASM). Testing including mapping, limited surface collection, and the excavation of hand units and backhoe trenches. Preliminary results of testing indicate that AZ U:10:122 consists of 32 rock features and a dispersed artifact scatter. Cultural materials at AZ U.122 (ASM) are limited to the surface with no subsurface artifacts present. Subsurface testing at AZ U:10:123 (ASM) identified two pithouses, three pits, and an area of cultural fill containing fire-cracked rock, charcoal, and burned organic material. Artifacts from both sites are of Hohokam manufacture; ceramics tentatively date AZ U:10:123 (ASM) to the Hohokam Sedentary-Classic period transition. Temporal information is not available from the limited ceramic collection at AZ U:10:122 (ASM). Based on the results of testing, AZ U:10:122 (ASM) appears to have limited information potential, and is not considered to be eligible for inclusion in the NRHP. The results of testing indicate that AZ U:10:123 (ASM) has the potential to contribute to further information regarding prehistoric use of the Salt river Valley, and it is considered to be eligible for inclusion in the NRHP. No further work is recommended for AZ U:10:122 (ASM); however data recovery investigations are recommended for AZ U:10:123 (ASM) to mitigate potential impacts from construction of the Red Mountain Freeway.

Archaeological investigations at Williams Air Force Base (WAFB), located in southeast Maricopa County, Arizona, were initiated in response to the 1991 Defense Base Closure and Realignment Commission’s (the Closure Commission) recommendation to close WAFB following the passage of the Defense Base Closure and Realignment Act of 1990 (the Closure Act) (Public Law 101-510, Title XXIX). SWCA, Inc., Environmental Consultants, conducted a cultural resource inventory on approximately 2000 acres of all portions of WAFB that had not been inventoried previously or were not occupied by existing facilities; inventory documents from previous investigations were examined as well. Three cultural properties (sites) were known from previous archaeological investigations at WAFB and on parcels adjacent to the base. The Midvale Site, AZ U:10:24(ASU), which lies under much of the administrative and residential area of the base, had already been surveyed and listed on the NRHP. The other two cultural properties (AZ U:10:20[ASU] and AZ U:10:25[ASU]) were re-examined and included in the evaluation process; the Midvale Site received no additional study. The cultural resource inventory for the 2000-acre portion of the base not previously inventoried resulted in the discovery and recording of nine additional sites (AZ U:10:60[ASM] through AZ U:10:68[ASM]). In order to define site boundaries and determine NRHP eligibility, a subsurface testing phase subsequently was implemented at eleven sites. Determination of boundaries during this phase was primarily for planning purposes and was not meant to be definitive. Following testing, 13 sites were defined within the base, including one site (a canal) that had not been identified during the cultural resource inventory. One of these sites is listed on the NRHP, four sites are not considered eligible for the NRHP, and eight sites are considered eligible for the NRHP. Revised treatment plan in accordance with the May 18, 1995 Programmatic Agreement.

Salt River Project (SRP) contracted with SWCA, Inc., Environmental Consultants, to conduct archaeological data recovery at the Overkill Site, AZ M:7:48(ASM), as part of the Mead to Phoenix 500 kV Transmission Line project. The Overkill Site is located on federal land administered by the U.S. Department of the Interior, Bureau of Land Management (BLM). The site is located approximately 15 miles south of Wikieup in Mohave County, Arizona. AZ M:7:48(ASM) is situated on a ridge between Burro Creek and Kaiser Spring Canyon, approximately 0.66 mile west of Highway 93 (Figure 1.1). The site was previously determined to be eligible for inclusion to the National Register of Historic Places (NRHP) by the Western Area Power Administration (WAPA) with agreement by the State Historic Preservation Office (SHPO). The Advisory Council on Historic Preservation, WAPA, and the Arizona and Nevada SHPOs signed a Programmatic Agreement that detailed the stipulations for construction of the transmission line in concurrence with SRP, the BLM, and the National Park Service (NPS). SWCA’s investigations were conducted under BLM Cultural Resource Use Permit No. AZ-000111. All material will be curated at the Arizona State Museum (ASM) in Tucson.

Archaeological investigations at Williams Air Force Base (WAFB), located in southeast Maricopa County, Arizona, were initiated in response to the 1991 Defense Base Closure and Realignment Commission’s (the Closure Commission) recommendation to close WAFB following the passage of the Defense Base Closure and Realignment Act of 1990 (the Closure Act) (Public Law 101-510, Title XXIX). Prior to closure or realignment of base facilities, preparation of an environment impact statement (EIS) was required, including documentation and evaluation of all cultural resources on WAFB. Each cultural resource was to be evaluated according to criteria established by the Secretary of the Interior for inclusion to the National Register of Historic Places (NRHP), with recommendations provided regarding each property’s eligibility and recommendations for future protection or treatment (National Historic Preservation Act of 1966, as amended). If a property was determined not to possess qualities required for inclusion to the NRHP, further protection or treatment would not be recommended. Should a property be found to possess such qualities, provisions would need to be developed to provide future protection. If a cultural property could not be protected, a treatment plan would need to be developed and implemented to mitigate impacts to that property. Insomuch as this document presents the findings of investigations at WAFB, it is also designed to provide the Air Force Center for Environmental Excellence (AFCEE) and the Air Force Base Conversion Agency (AFBCA) with information necessary to develop a Record of Decision that will detail acceptable measures of protection or treatment for each NRHP-eligible property. AFCEE contracted with Halliburton NUS Corporation to complete the EIS for WAFB. Halliburton NUS in turn subcontracted SWCA, Inc., Environmental Consultants, under Subcontract No. 4011 -92- 014, to conduct the cultural resource inventory for all portions of WAFB that previously had not been inventoried or were not occupied by existing facilities. SWCA conducted investigations on approximately 2000 acres of the base and examined inventory documents from previous investigations. Three cultural properties (sites) were known from previous archaeological efforts at WAFB and on parcels that lay adjacent to the base. The Midvale Site, AZ U:10:24(ASU), which lies under much of the administrative and residential area of the base, had already been surveyed and listed on the NRHP. The other two cultural properties (AZ U: 10:20, ASU, and AZ U: 10:25, ASU) were re-examined and included in the evaluation process; the Midvale Site received no additional study. In order to determine the number of cultural properties present at WAFB and to develop recommendations for those cultural properties, two levels of examination were necessary. First, a cultural resource inventory for the 2000-acre portion of the base not previously inventoried was conducted, resulting in the discovery and recording of nine additional sites (AZ U: 10:60, ASM, through AZ U: 10:68, ASM). The results are presented as Part I of this document. Second, to define site boundaries and determine NRHP eligibility, a subsurface testing phase was implemented at eleven sites. The boundary definition that took place was done primarily for planning purposes and was not meant to be definitive. Additional testing or monitoring may be required if construction occurs near the "boundary" of a National Register eligible site, and extent testing will be required on any eligible site prior to implementation of development plans. The results of testing are presented as Part II.

In consultation with the Arizona State Historic Preservation Office (SHPO), HALLIBURTON NUS conducted a preliminary data collection effort and "Class I Overview" of the Williams AFB property and surrounding area. This consisted of a literature search and review of files at the SHPO. The Class I Overview identified three archaeological sites on the Williams AFB property. The Midvale Site (AZ U:10:24, ASU) consists of a large prehistoric Hohokam village considered to be of cultural importance. The site has been studied in some detail, delineated, and listed on the National Register of Historic Places (NRHP). The two other sites (AZ U:10:20, ASU, and AZ U:10:25, ASU) have been preliminarily identified on the basis of surface artifacts. Their areal extent has not been well defined, and it is not known whether they possess attributes that would qualify them for eligibility for the NRHP. A small portion of Site AZ U:10:20 (ASU) has received test excavations, but these efforts resulted in few data that would support NRHP eligibility of this site within Williams AFB (Goodfellow 1989). Most of the rest of the Williams AFB property had not been examined prior to this time for the presence of archaeological resources. However, because numerous such sites exist in the area surrounding Williams AFB, a strong possibility that other areas of the base also contain archaeological resources was considered likely.
