Archaeological Excavations for Phase I of the Civic Plaza Expansion Project, Phoenix, Arizona

Summary

The City of Phoenix is renovating and expanding the Civic Plaza in downtown Phoenix. The project involves demolition of the North Hall and construction of a larger, replacement facility in the same area, as well as construction of a new Terrace Building on Symphony Terrace. The interior facilities of Symphony Hall and the South Hall also will be renovated and refurbished.

The project is not a federal undertaking subject to Section 106 of the National Historic Preservation Act. The State of Arizona will provide up to $300 million to match City of Phoenix expenditures for the project, but State payments will not begin until the facility is built and opened in 2009. Currently no state agency is involved in the project. The City of Phoenix retained URS Corporation to conduct archaeological investigations to assist in complying with the Arizona Antiquities Act and policy established by the Phoenix General Plan.

No archaeological or historical studies were conducted prior to the original 1960s construction of the Civic Plaza, but investigations for subsequent projects in adjacent areas have discovered prehistoric and historic archaeological resources. The expansion project encompasses six blocks of the original Phoenix townsite, and archaeological remnants of early settlement may be present. Prior studies also have shown that part of the project area is within the boundaries of a prehistoric Hohokam archaeological site known as Pueblo Patricio. Although the original construction would have destroyed archaeological resources that might have been present within much of the expansion project area, review by the City Archaeologist concluded that disturbance might have been relatively shallow in some areas and archaeological resources may remain intact in those areas.
