In reaching the conclusions called for by Section 751.60, the court shall give effect to the changes in land boundaries caused by the disaster, mitigated, however, so far as can equitably be done by adjustment of land boundaries and by allocating to contiguous lots parts of the land released by a city, county or the state by its voluntary vacation of areas formerly constituting public ways, which vacatings of streets shall be approved by the judgment.
