(5)Scale Transitions

In order to provide a transition in scale from new structures to existing structures on the boulevards fronting on the rivers, development on sites next to existing structures which exceed the height limitation created by the inclined planes may exceed the height limitation by fifty (50) percent of the extent to which the existing structure exceeds the height limitation, providing that any portion of the new structure above the inclined plane achieve a minimum setback of twenty (20) feet from property lines along Fort Pitt Boulevard and Fort Duquesne Boulevard.
