The City Council has asked City Attorney Turner Smith to review a proposed ordinance that would grant tax exemptions to rehabilitated real estate throughout the city. The original ordinance included only certain districts, mainly the city's historic area, according to Vice Mayor Stewart Vetter. In addition, Commissioner of Revenue Arthur Shoemake asked the council to delay passage of the ordinance until his office has time to study its impact on the city's income. The proposal would give tax-exempt status to substantially rehabilitated residential property if the improvements increased the assessed value of the structure by no less than 40 percent. Commercial and industrial property must be improved no less than 60 percent to qualify for the exemption.

The Manassas area will be served by the University of Virginia's new rescue emergency helicopter, which began operation recently. The helicopter, which operates 24 hours a day with a rotating 11-person crew, will provide emergency medical care as well as speedy transportation to hospitals. It will also serve Winchester, Staunton, Harrisonburg, Farmville, areas in Southwest Virginia and parts of West Virginia.
