Project Goal

Business Problem Solved

In 2013, the State of Iowa Legislature passed a tax reform law allowing qualified commercial, industrial and railroad properties (a parcel or parcel unit) to apply for a business property tax credit. Administered through the Iowa Department of Revenue, local governments are required to submit parcel geometry and associated abstract attributes that coincide with the property tax credit application. Through this process, the Department of Revenue has been able to work toward a yearly refresh of parcel geometry and attributes. Legislation also introduces a concept called the parcel unit which is defined as two or more contiguous parcels. GIS tools are playing an important role in validating this contiguous parcel unit component of the tax credit application process.

Technology Implemented

Data extract, transform and load (ETL) procedures as well as aggregation workflows were implemented using ArcGIS 10.4 and the Community Parcels Solution, customized Python scripts and ArcGIS Server. Data is being made accessible for other State of Iowa governmental units through ArcGIS REST services and integrated into the Department of Revenue Local Government Exchange portal using Esri's ArcGIS API for JavaScript.
