See Uniform Act, § 301 (3), 42 U.S.C. § 4651(3). This is an express statutory exception to the rule that property must be valued as it existed on the date of value. E.g., Rasmuson , 807 F.3d at 1346 (noting that a calculation that does not consider existing conditions “will result in an artificially inflated value and yield a windfall”); cf. 161.99 Acres in Collins , 512 F.2d at 66 (holding compensation must be measured as of date of taking, regardless of subsequent changes in property’s market value).
