This Ordinance establishes separate districts, each of which is an appropriate area for the location of the uses which are permitted in that district. Within such established districts as well as those which may be established by future amendments, there are and will be lots, uses of land, structures and uses of structures and land in combination which were lawful before this Ordinance was passed or amended, but which would be prohibited, regulated, or restricted under the terms of this Ordinance or future amendments. Since such nonconformities are deemed incompatible with the districts in which they are located, it is the intent of this article to specify those circumstances and conditions under which such nonconformities shall be permitted to continue, but not to encourage their survival. Rather, it is the intent of this Ordinance to encourage either for the conversion of nonconforming uses into conforming uses as soon as reasonably possible or for their eventual and equitable elimination.
