The Metro Council is advancing an ordinance that would allow Nashville's property assessor to offer prorated property assessments for those who suffered significant damage from the winter storm that devastated Middle Tennessee. To qualify, the property must have been uninhabitable or inoperable for more than 30 days and the damage is 50 percent of the building's value. Property Assessor Vivian Wilhoite recommends starting collecting the paperwork necessary for the application. The ordinance still requires another reading to pass.
