An intensive archeological survey was completed in order to inventory and evaluate archeological resources within the footprint of proposed improvements to Pan American Drive and Winn Road in El Paso County, Texas. The proposed improvements would extend Winn Road from Pan American Drive to Rio Del Norte Drive, resurface Pan American Drive from Loop 375 to Winn Road, and expand an existing detention pond. The proposed improvements along Pan American Drive and Winn Road are approximately 2.03 miles (3.27 kilometers) long with a typical width of 90 feet (27.43 meters). The archeological area of potential effects (APE), including the expansion of the detention pond, covers an area of 31.18 acres (12.62 hectares). Typical roadway construction would extend 2 feet (0.6 meters) to 3 feet (0.91 meters) below the ground surface, with deeper impacts at the detention pond.

Fieldwork was conducted on March 1 and 2, 2017, under Texas Antiquities Permit 7927. Both shovel testing and mechanical trenching were utilized during survey. Most of the proposed new right-of-way falls in sparsely vegetated sand dunes along the edge of a heavily modified playa that has been converted to a detention pond. No archeological sites or isolated artifacts were documented during the survey. Project records will be curated at the Center for Archaeological Studies at Texas State University-San Marcos.

The Texas Department of Transportation-Environmental Affairs Division and Texas Historical Commission concurred with the findings of this report on June 8, 2017 (see Appendix B).
