The April 18th Boundary Technical Working Group has been cancelled but will be on again in May.
As an update, counties in DIGB 5 (southeast Idaho) will be meeting in-person for a County Boundary Review “Party” on April 14th at Bannock County to discuss remediation of gaps and overlaps at their shared county boundaries. Many other counties across the state have also been coordinating with each other to remedy issues. You can see their progress on the Idaho County Boundaries Reviewer Map – https://experience.arcgis.com/experience/75df84dc63614a07a34673c3103dd8b6.
