1165.03 BUILDING LINES ESTABLISHED.
   (a)    Building Lines Established. Along every street right-of-way a building line shall be established from the existing right-of-way or proposed right-of-way as indicated in the Obetz Thoroughfare Plan, as amended, whichever is greater in width, that shall constitute the required front yard setback as established in the applicable zoning district.
   (b)    Required Setback Defined. The required setback is that distance between the established building line and the actual or proposed right-of-way. No structure or other use of land, except parking as defined in subsection (c) herein, shall locate in the required setback. In no case shall the required setback be less than the minimum required in the applicable zoning district.
   (c)    Parking Within the Required Setback in Commercial and Industrial Districts. Open parking or loading spaces shall be permitted to extend toward the street right-of-way from the established building line a distance equal to forty (40) percent of the required setback distance as measured from the actual or proposed right-of-way. In no case shall any part of a parking area be closer than fifteen (15) feet to any established or proposed right-of-way.
   (d)    Reduced Setback. If existing structures or uses on lots adjacent to each side of a lot have a setback less than the setback line established by these Regulations, the setback on the center lot shall be the average setback established on the adjacent lots.
   (e)    Display in Front Setback Prohibited. Within the front building setback and side building setbacks adjacent to public right-of-way, there shall be no storage or display of any materials, equipment, inventory, merchandise or wares. This provision is applicable in all zoning districts.
   (f)    Setback Requirements for Corner Buildings. On a corner lot the principal building and its accessory structures shall be required to have the same setback distance from all street right-of-way lines as required for the front yard in the district in which such structures are located.
   (g)    Visibility at Intersections.
      (1)    On a corner lot in any residential district, nothing shall be erected, constructed, placed, planted or allowed to grow in such a manner as materially to impede vision between a height of two and one-half (2 1/2) feet and ten (l0) feet above the center line grades of the intersecting streets in the area bounded by the street lines of such corner lots and a line joining points along said street lines fifty (50) feet from the point of the intersection.
      (2)    In nonresidential zones at intersections of street rights of way, a sight triangle shall be established as described by the right-of-way lines of the intersection streets and the third side being a line passing through a point on each right-of-way line that is a distance from their point of intersection equal to the sum of the width of both rights of way divided by four.
