Developers seeking an exception to this requirement must show reasonable evidence that, (1) the thoroughfare will provide no benefit to their development, or (2) the size or shape of the parcel is such that right -of -way in excess of 60 feet will physically prevent the use proposed for the parcel. The developer shall pave with curb and gutter, both sides of a major throughfare along which he retains commercial acreage abutting the right -of -way. Where the developer proposes residential development along the major thoroughfare, the city may participate to the extent of one -half the paving and drainage cost along the residential section. Example 1: A developer plats a subdivision containing a portion of a major street, but retains commercial frontage on both sides of the street right -of -way. He would be required to pave both sides of the dual 24 -foot pavement. Example 2: A developer plats a subdivision containing a portion of a major street with residential lots on both sides of the street. The city may participate in the paving -25- W 80713 -llbb and drainage to the extent of one 24 -foot pavement and one - half the drainage cost of the lots abutting the major street. Example 3: A developer plats a subdivision containing a portion of a major street with one side commercial and one side residential. The city may participate to the extent of one -half the paving and drainage cost of the street. (For example the city may pay for 12 feet of paving plus one -half of any storm sewer serving the residential side of the street). (d) Right -of -way width (from Engineer Standards).
