D. 
Affordable housing requirements. The following affordable housing requirements shall apply to development in the COAH-3 Zone:
(1) 
All residential development constructed in the COAH-3 Zone shall be required to set aside a minimum percentage of units for affordable housing. The minimum set aside shall be 20%. When calculating the required number of affordable units, any computation resulting in a fraction of a unit shall be rounded upwards to the next whole number.
(2) 
All affordable units to be produced pursuant to this section shall comply with the required bedroom distribution, be governed by controls on affordability, and affirmatively marketed in conformance with the Uniform Housing Affordability Controls (UHAC) (N.J.A.C. 5:80-26.1 et seq.), or any successor regulation, with the exception that in lieu of 10% of the affordable units being required to be affordable to households earning 35% or less of regional median income by household size, at least 13% of affordable units shall be required to be affordable to households earning 30% or less of regional median income by household size.
(3) 
Each affordable unit shall remain subject to these affordability controls, covenants, conditions, deed restrictions, and the applicable affordable housing regulations for a minimum period of at least 30 years. At the conclusion of the thirty-year term, the affordability controls, covenants, conditions, and deed restrictions shall automatically be extended unless the Borough takes formal action to release the affordable unit from such requirements by formal adoption of an ordinance taken in compliance with N.J.A.C. 5:80-26.11(c) or any other applicable statute, regulation or law that may be in effect at that time. The Borough shall also maintain the right to exercise any other option(s) available to the Borough to preserve the affordability controls as set forth in UHAC or other applicable statute, regulation or law that may be in effect at that time.
(4) 
All affordable units shall be administered by a qualified administrative agent paid for by the developer. The developer shall be responsible for all costs associated with the initial sale/rental of the affordable units, for the continuing administration of the affordable units, and for the preservation of the creditworthiness of the units.
(5) 
All of the affordable units shall be rental units and may be permitted as multifamily dwellings. Affordable townhouse dwellings shall not be required but are permitted at the election of the developer.
(6) 
All amenities and site services which are made available to the market-rate units shall also be made available to the affordable units on the same terms as the market-rate units.
