(RECAP: Hoping to capture a portion of the anticipated growth along Columbia Pike, the Arlington County Board said Saturday that it wants to use tax tools to help nonprofit developers pay for affordable housing along the rapidly developing road. Board members described the proposal to set up a tax increment financing fund for the area as “creative” and “innovative” because it would capture 25 percent of any new real estate taxes and dedicate that money to a fund that would pay for infrastructure and fees, thus allowing nonprofit developers, who build most of Arlington’s affordable housing, to qualify for tax credits.)
