D. Elevator and stair penthouses, water tanks, monitors and scenery lofts, provided no linear dimension of any such structure exceeds fifty (50) percent of the corresponding street lot line frontage; or to towers and monuments, fire towers, hose towers, cooling towers, gas holders or other structures, where the manufacturing process requires a greater height.

E.
