YARD
An open space at grade between a building and the adjoining lot lines, unoccupied and unobstructed by any portion of a structure from the ground upward, except as otherwise provided. In measuring a yard for the purpose of determining the width of a side yard, the depth of a front yard, or the depth of a rear yard, the least shall be used. Where lots abut a street that is designated a thoroughfare on the Thoroughfare Plan, all yards abutting said street shall be measured from a line one-half the proposed right-of-way width from the center line, or from the lot line, whichever provides the greater setback. On other lots, all yards abutting a street shall be measured from a line 25 feet from the center line, or from the lot line, whichever provides the greater setback.
