The City of Tempe (COT) is planning construction of a multiple-use path (MUP) and streetscape improvements project along the 8th Street corridor between Rural Road and McClintock Drive. The area of potential effects (APE) is entirely situated within AZ U:9:165(ASM)/La Plaza and incorporates an alignment of AZ U:9:298(ASM)/Creamery Branch Railroad. The former is a multicomponent site that has been recommended eligible for listing in the NRHP under Criterion D (information potential) and the latter is a historic railroad that has been recommended eligible for listing in the NRHP under Criterion A (important events/history). Logan Simpson involvement with the 8th Street MUP project was in part due to recommendation from local tribal representatives to the City to engage with a firm like Logan Simpson given the sensitivity of the resources in the project area.
Logan Simpson provided the COT with cultural resources services, including coordination and permitting, consultation, revision of existing Class I and Class III cultural resources reports, preparation of a Historic Properties Treatment Plan (HPTP), and execution of Phase I testing according to the HPTP. The project required project registration, an AAA project-specific permit, and burial agreement from the Arizona State Museum (ASM). Logan Simpson coordinated with the Arizona Department of Transportation (ADOT), the State Historic Preservation Office (SHPO), ASM, and COT to obtain the necessary project permits and approvals. Phase I testing consisted of 27 mechanically excavated trenches that revealed 24 prehistoric period features and 11 historic period features. These included a prehistoric human burial, pits, buried surfaces, canal segments, and structures along with historic railroad related features, buried surfaces, utilities, and irrigation ditches. Significantly, Logan Simpson archaeologists argue they discovered the remains of an exceptionally rare prehistoric Hohokam platform mound.
Logan Simpson has worked closely with Native American tribes throughout the course of our involvement with the MUP project. We hosted a consultation meeting between the COT, ADOT, SHPO, and tribes held to discuss next steps following Phase I testing. Furthermore, we coordinated closely with the Salt River Pima-Maricopa Indian Community and other tribes to develop an addendum to the HPTP that called for close coordination with the tribe during Phase II data recovery, and our work plan includes close interaction with the tribes to ensure that this very important resource is handled in a way that is consistent with tribal values. In addition, Logan Simpson included an ethnographic study to address tribal questions in the HPTP addendum.
