Where the planned development provides open space areas or recreation facilities which
are privately owned, but commonly shared among the property owners, and such open
space and/or recreation facilities are not maintained in a condition consistent with
the approved development, the city may, at its option, cause such maintenance to be
performed and assess the cost to the affected property owners or responsible homeowners'
association, or cause a lien to be placed on the affected property, to be collected
with the taxes thereon.
