Fairfax County supervisors on March 5 disagreed on which areas should be established as Economic Revitalization and Redevelopment Zones and how much land would be needed to qualify, but they unanimously approved an April 9 public hearing to discuss the initiative. Under the zones, which may be established under a 2017 state law, the county government could give developers regulatory incentives such as expedited application processing, inclusion of the applications under the county’s Land Development Services Project Management Program and site-plan-review discounts of up to 10 percent. Private-sector builders who assembled and developed private parcels also could receive partial real-estate-tax abatements, which would apply only to Fairfax County’s real-estate tax and not to other levies, such as special-district taxes or the county’s commercial-and-industrial tax. County staff would overlay those areas on maps and prioritize them, said County Executive Bryan Hill.If supervisors approved the necessary county-code amendment, the program would take effect Jan. 1, 2020, and expire Dec. 31, 2029.To be considered for the program, developments would have to consist of newly consolidated land featuring at least two parcels and covering 2 acres, and retain or repurpose no more than 20 percent of existing development. Under the initiative, county staff periodically would update the Board of Supervisors on the number of applications received, the status of qualifying projects and the program’s financial impacts. Consolidating lots for the minimum 2 acres could be difficult in older parts of the county, such as Annandale, said Supervisor Penelope Gross. Supervisor Linda Smyth said the board would have to look at revitalization areas individually.
