The CCAO adjusted residential property values down by 8-12% per Neighborhood because of COVID-19. These adjustments varied by location and were meant to track the predicted depreciation in market prices as unemployment increases because of the pandemic.


For this reassessment, the CCAO met both of its internal fairness benchmarks. The CCAO reported that its valuations were low in variability and vertically equitable.
