Utah Court of Appeals
958 P.2d 245 (Utah Ct. App. 1998)
A zoning ordinance must be reasonably related to serving the public health, safety, or general welfare. If a land use restriction is unreasonable or irrational, it may be found to violate the substantive component of the due process clause.
If an ordinance could promote the general welfare; or even if it is reasonably debateable that it is in the interest of the general welfare, it is valid. The focus is not on the alleged or potential effects, but on the ordinance itself, and the justification for adopting it.
The selection of one method or approach over another is entirely within a local government’s discretion.
