The intent of the OR Office Residential District is to:
A.
Recognize an area of existing single-family houses which may have declined in suitability as residences because of immediate proximity to arterial streets experiencing increases in traffic and to industrial uses.
B.
Provide an option to these landowners to continue to maintain a residence or to convert to a limited commercial use.
C.
Make sure that any commercial use would not be so intense as to create nuisances to neighboring residences or additional traffic hazards.
