Chronicle Heritage, a Phoenix-based archaeology and cultural resources company, is closing its operations and laying off all 108 employees at its midtown office, according to a Worker Adjustment and Retraining Notification filed with the Arizona Department of Economic Security. The company is permanently closing its office at 2025 N. 3rd St. The shutdown is expected to affect about 600 employees companywide. Chronicle Heritage conducts archaeological reviews and other land surveys for developers and government agencies. Those assessments can help clients meet regulatory requirements before beginning proposed development projects. The closure removes a local provider of those services and ends 108 Phoenix-area jobs. The layoff notice identifies the scale of the local cuts and the office closure; no reason for the shutdown was included in the available details.
