If a housing development is otherwise eligible for a density bonus under the provisions of this section; the development includes a child day care facility other than a family day care home, including, but not limited to, an infant center, preschool, extended day care facility or school-age child care center, that will be located on the premises of, as part of or adjacent to the development; and the city does not find, based upon substantial evidence, that the community has adequate child care facilities, the city shall grant one of the following:
