Right-of-way easements for streets and roads shall not be considered a part of a lot or open space or front, rear, or side yard for the purpose of meeting yard requirements.

No yard or lot existing at the time of passage of this ordinance shall be reduced in dimension or area below the minimum requirements set forth herein. Yards or lots created after the effective date of this ordinance shall meet the minimum requirements established by this ordinance.

Where the owner of a lot at the time of the adoption of this ordinance does not own sufficient land to enable him to conform to the frontage setback or area requirements of this ordinance, such lot may nonetheless be used as a building site.
