(plaintiff’s zoning board denied defendant’s request for a special land-use permit to construct a motocross complex on a parcel of land; after plaintiff received complaints that defendant proceeded with its plan despite the denial, plaintiff sought an injunction preventing defendant from constructing and operating the complex; the trial court denied defendant’s claims that the zoning ordinance violated its due process and equal protection rights, but amended its preliminary injunction to allow defendant to construct one track on the property and to ride up to six machines on the track every second and fourth weekend of the month; in affirming, the court ruled that the trial court did not err in determining that defendant’s planned activities constituted a public nuisance and nuisance per se; the zoning board’s actions were rationally related to the legitimate purpose of protecting the public health, safety, and welfare of its residents, and defendant was not treated in a dissimilar manner from similarly-situated businesses; denial of the special use permit did not constitute a regulatory taking).
