(b) An offer of dedication may be terminated, and the right to accept the offer abandoned, by a majority vote of the board of directors of the district and only if the board of directors makes both of the following findings:

1. (1) The offer of dedication was never accepted and, therefore, termination or abandonment of the offer does not constitute a conveyance of an interest in real property dedicated for park or open-space purposes.
2. (2) Now, or in the future, the district cannot effectively use the real property, or interest in real property, that would be conveyed by the offer of dedication for park or open-space purposes.
