(1) Each extremely low and very low income household unit qualifies the overall development for two bonus dwelling units up to a maximum of a 50% increase over current zoning; and
(2) Each low income household unit affordable to households at or below 60% of AMI qualifies the overall development for one bonus dwelling unit up to a maximum of a 50% increase over current zoning.
