For instance, if the denial of a permit for a period of three years precluded the use of a property for commercial purposes, a secondary use of industrial warehousing during the taking period would not be appropriate because the short-term life of the secondary use would not be economically feasible. However, a secondary use as an industrial equipment storage yard might be a suitable secondary use because such a use would not involve the construction of substantial improvements or a commitment to a long-term use.
