Sec. 6-4. - Same—Commercial buildings with slab floors.

In cases where slab floors are to be constructed as the foundation of a commercial building, the elevation of the slab floor above the curb of the street in front of the property on which such commercial building is being constructed shall be an elevation determined by the following formula:

One-fourth inch of elevation above the curb for each foot of distance between the curb and the property line and one-eighth inch of elevation for each foot of distance between the property line and edge of the slab floor.

In no case shall the slab floor be constructed less than four inches above the top of the curb. Where no curbs exist, the location and elevation shall be obtained from the city engineer, and such location and elevation shall be used to determine the elevation of the floor slab.
