However, no arguments are advanced by Defendants as to how the prohibition of the regulated uses within 500 feet of a single dwelling or rooming unit furthers the legitimate interest the City has in preserving a residential area or neighborhood. Indeed, where only a single dwelling or rooming unit is involved, we fail to see how the prohibition of the Ordinance affords any protection whatsoever to a neighborhood or residential *370 area.[1] We must weigh this imperceptible benefit to the City's stated interest against the severe impact imposed by the Ordinance on the Plaintiffs. No area of the City is specifically set aside or designated for the regulated uses. There are few, if any, locations other than industrial areas and the downtown commercial area of Detroit where there is not a single dwelling or living unit within 500 feet. Thus, the effect of the restriction is an almost total ban on uses conceded by the Defendants to be lawful. While such an extreme effect might not render the restriction invalid under the equal protection clause if the City had demonstrated that its compelling interest was promoted thereby, no such showing has here been made. We conclude that the 500-foot restriction is not necessary to promote any expressed compelling State interest and is therefore invalid under the equal protection clause.
