Macomb, IL – An updated set of aerial photos is helping the McDonough County assessor's office find new construction to go on the tax rolls. Supervisor of Assessments Tammy Camp says some people voluntarily report when they build something. Others are more willing to tell her office only when they take down a structure. Camp says the photos not only show new construction, but whether something reported as being torn down actually has been. Camp says after appeals are resolved, staffers will compare old and new photos, section by section, to look for changes.
