Case Study: Coconino County achieves $2.24M increase in assessed value and streamlined, equitable property valuations with Tyler Technologies' Assessor Plus

Coconino County, Arizona, uses Tyler's Eagle software to enhance operations

Coconino County Assessor’s Office in Flagstaff, Arizona — which serves a population of about 140,000 across roughly 19,000 square miles — faced challenges managing self‑reported business personal property data. Staff were doing time‑consuming, manual line‑by‑line entries and lacked a standardized, central system to validate multi‑year records, prompting a countywide audit to improve data accuracy, taxpayer education, and reporting capability.

The county implemented Tyler’s Assessment & Tax Plus (Assessor Plus) as a single data repository, built automated workflows, and began digital uploads (Excel imports) to cut manual entry and streamline reviews. The new system improved reporting, audit throughput, and constituent communication — yielding a $2.24 million increase in new total value in year one, ongoing improvements in efficiency and transparency, and stronger trust with local businesses.
