Cultural Resources Survey for the SRP Pinal South Substation Southwest of Coolidge, Pinal County, Arizona

Author(s): Tiffany C. Clark

Year: 2007


This report presents the results of a Class III cultural resources survey of approximately 120 acres of privately owned land southwest of Coolidge, Pinal County, Arizona. The work was requested  by  Salt  River  Project  Agricultural  Improvement  and  Power  District  (SRP)  to determine if significant cultural  resources were  present within the  surveyed property.  SRP is currently  acquiring the parcel and is planning to construct an electrical substation (Pinal South)  on  the property.  The Pinal South Substation will be part of the larger Pinal West to Southeast  Valley/Browning  extra-high  voltage  transmission  line  project.  This  line  has recently  received  a  Certificate  of  Environmental  Compatibility  from  the  Arizona Corporation  Commission  (Case  No.  126).  The  Pinal  South  Substation  is  sponsored  by  a consortium  of  private  electrical  utilities  including  SRP,  Electric  Districts  2  and  4  of  the Tucson Electric Power Company, and Southwest Transmission Cooperative, Inc.

The cultural resources survey was conducted on 6-7 February 2007, by Dr. Tiffany Clark and Connie Darby of Desert Archaeology, Inc. Dr. Henderson served as Principal Investigator for the project. Although the surveyed land is private and no archaeological permit is required, Desert Archaeology does hold a current Arizona Antiquities blanket permit (Permit No. 2007-002bl) for conducting non-collection surveys within the state. Two archaeological sites, AZ AA:2:284 (ASM) and AZ AA:2:285 (ASM), and 27 isolated occurrences were recorded within the project area. Both sites are considered eligible for listing on the National Register of Historic Places and may contain significant subsurface remains that could be impacted by construction of the substation. These findings are the substance of this report, along with recommendations for avoidance or further treatment of the significant cultural properties. A description of the project area, environmental and cultural background information, a summary of previous research, and description of survey methods preface these discussions.
