Any lawful nonconforming sign, as defined in Article
XVIII, §
475-130, herein, may be maintained in its present form, i.e., as it exists on the effective date of this chapter, so long as such sign continues to be in safe condition and in good repair; however, such sign may neither be replaced nor repaired at a cost exceeding 50% of the sign's original value. In addition, any sign maintained in connection with and upon the same lot as a sign similar in size and character so long as such lawful nonconforming use continues, but may not be enlarged or otherwise substantially altered except in accordance with the regulations contained in Article
XVIII herein.
The development of any lot held in single and separate ownership on the effective date of this chapter which is not of the required minimum area or width, or is of such unusual dimensions that the owner would have difficulty in providing the required setback areas for the district in which the lot is situated, shall be permitted in accordance with the requirements of Article
IV, §
475-13, herein. In the case of an existing conforming use on a nonconforming lot, expansion of such use shall be permitted, and shall not require a special exception or variance, so long as all applicable requirements, other than lot area and width, are satisfied.
The Zoning Officer shall perform a survey of the Borough and
record and map all uses nonconforming to the district requirements
set forth in this chapter. Such record and map shall be available
for inspection at the Borough municipal building.
