The constitutionally required "just compensation" in partial takings is usually measured by fair market value of the part taken, plus severance damages (the diminution in value of the property retained by the owner [remainder] when only a part of the subject property is taken). Where a partial taking provides economic benefits specific to the remainder, those must be deducted, typically from severance damages. Some elements of value, such as a business's connection to the location and the goodwill of the public, are only compensable in a few jurisdictions; where they are not, fair market value may be less than the value of the location to the current user.
