Thanks to the town's Land-Use Management Ordinance, 15 percent of units in most new residential developments must be affordable housing - defined by the Chapel Hill Town Council as any unit affordable for individuals or families whose incomes are at or below 80 percent of the area median income for a family of four.
That's a rule the town should work to keep up, and recent efforts by the council to bolster the plan should be applauded.
As the rule now stands, if the number of required affordable units in a development isn't a whole number, the town rounds down. So a 10-dwelling project needs one unit of affordable housing, not two.
But the council is considering making those numbers round upward instead, and that's a good thing.
Roger Waldon, the town's planning director, made a strong point when he noted that such an alteration in the ordinance's language would make housing rules more consistent with other town-related requirements.
