(A)   Generally. Building setback restrictions have traditionally been required by the city in various degrees dependent upon the type and design characteristic of the streets which the restrictions parallel. These restrictions are designed and applied to assure that occupied buildings, particularly residential and commercial buildings where a concentration of people is involved, are located a sufficient distance away from the adjacent street to avoid damage to the structure and occupants by errant vehicles, to lessen or minimize the effect of noise and pollutants generated by traffic on the occupants of adjacent buildings, to ensure that the location of buildings do not create any traffic hazard by blocking or restricting lines of sights, particularly at intersections and along curves, to provide some additional open space in addition to the space within the street right-ofway for the free movement of police, firefighters, and others in emergency situations, and when appropriate sufficient yard space and open space separating building structures which may enhance the visual character and value of a particular development. Building setbacks shall be established and maintained as provided herein and shall in no case be less than the building setbacks established in the city zoning regulations found in Chapter 155.
   (B)   Major thoroughfares. Properties adjacent to designated major thoroughfares must have a front building setback from the adjacent major thoroughfare right-of-way of not less than 25 feet. When the lot sides on a major thoroughfare, a side building setback of at least 20 feet must be provided. In those instances where such a lot backs on a major thoroughfare, a rear building setback of not less than ten feet will be required.
   (C)   Local streets. Properties adjacent to local streets must have a front building setback from the adjacent street right-of-way of not less than 25 feet. When the lots side on a local street, a side building setback of 15 feet must be provided. When the lots back on a local street, a rear building setback of ten feet must be provided.
   (D)   Building setback line off-sets and transitions. In those instances where the required building setback restriction line changes from one tract to another, a transitional building setback line must be provided having a minimum angle of 45 degrees. The transition must take place on the lot or tract having the lesser building setback restriction requirement.
   (E)   Pipelines; railroad rights-of-way. Where underground pipelines carrying flammable products under pressure through properties within a plat boundary or where properties within the plat back or side along a railroad right-of-way, a 15-foot building setback restriction must be provided adjacent to the pipeline easement or fee strip (or the center line of the pipeline facility if no easement is defined) or railroad right-of-way line.
