Data Transparency  

Data transparency is of the upmost importance to our office. We want to assure our residents that data being reported are accurate and are coming from the official source. 

  • Interactive Assessment Transparency Tool 2021: In collaboration with our GIS department, the Assessor’s Office has an interactive map demonstrating value changes from the 2019 to 2021 general reassessment for residential parcels. This tool allows searches to reveal values, links to parcel information, demonstrates average value within the field of view and also overlays sales within the relevant time period.
