Important Announcements

We are thrilled to share that we are currently converting to a new, modern assessment system: Arist.

While this advancement in our technology is underway, changes to our processes, applications, timing, and procedures may occur. We thank you for your patience while we install and implement this new fully-GIS integrated system. We are proud that we will soon utilize and provide our citizens with this leading-edge technology. Stay tuned! We will provide updated information and instructions as available.
