United States v. Petty Motor Co. , 327 U.S. 372, 379-80 (1946); see Kimball Laundry , 338 U.S. at 15 (“The temporary interruption as opposed to the final severance of occupancy so greatly narrows the range of alternatives open to the condemnee that it substantially increases the condemnor’s obligation to him. It is a difference in degree wide enough to require a difference in result.”).
