Replacement. If a nonconforming structure is damaged or destroyed
by violent wind, vandalism, fire, flood, ice, snow, mold, infestation,
or other calamity, the nonconforming structure may be reestablished
to the extent it existed before the damage or destruction, provided
that no new or greater nonconformities are created and a permit application
to allow the reestablishment is filed within one year of the date
of damage or destruction.
