In the event a person proposes a subdivision, which includes a plan and a program
for a complete community or neighborhood, including the dedication of adequate public
sites and improvements, the city council may accept the dedication of such sites and
improvements in lieu of the tax levied by this article; provided, that the value of
such space and improvements, as determined by the city council, apportioned over the
number of dwelling units and mobile home spaces to be developed is substantially equal
to the amount of tax levied by this section; and, in the event the dedications referred
to above do not substantially equal in value the amount of taxes levied and measured
as set forth in this section, as determined by the city council, the city council
may accept such dedications in partial payment of such taxes and collect the remainder
thereof in cash.
