GIS/ValTech 2027

Maricopa County built a spatial tool in ArcGIS Experience Builder for comparing parcel characteristics and attribute data on an interactive map. Including properties, neighborhoods, subdivisions, parcel class, improvement areas, and more. With a huge parcel count, it enables parcel-level review and catches data inconsistencies through custom queries and filters. We'll cover how it works, how it was built, and its growing role and reputation as an office-wide data quality tool.

Orleans Parish applied that same "see it differently" idea to appeals. We'll walk an appeal end to end from submission, staff review, valuation, decision, documentation, and taxpayer communication. Then showing how digital workflows, AI-assisted valuation, and virtual assistance make the process faster, more transparent, and more consistent, without losing professional judgment.
