The developer may in all cases round the set-aside upward and construct an additional affordable unit; or if the set-aside includes a fractional unit of 0.2 or less, the developer may round the set-aside downward and construct the lower whole number of affordable units, but must also make a payment in lieu of constructing the fractional additional unit ("fractional payment-in-lieu"). The fractional payment-in-lieu amount shall be calculated as the fractional unit multiplied by the payment-in-lieu amount of $250,000, increased annually by the Urban Consumer Price Index for the metropolitan area.
For example, if seven total units are developed at an inclusionary site, a 20% set-aside would require 1.4 affordable units. The developer must round up the fraction and construct a total of two affordable units. If six total units are developed, a 20% set-aside would require 1.2 affordable units. In that instance, the developer may either round up and construct a second affordable unit, or make a fractional payment in lieu of 0.2 x $250,000, or $50,000, into the Township's Affordable Housing Trust Fund.
