The question presented is the validity under Missouri law of a zoning ordinance adopted by the Town of Loma Linda, Missouri. Under the ordinance, one-family dwellings of a single story must have a minimum of 1,800 square feet of above-ground living space, if they are located within a certain part of the Town. Plaintiffs own land affected by the ordinance. Under covenants applicable to the property, a minimum square footage of 1,640 was already in effect. Plaintiffs claim that the requirement of an additional 160 square feet is unreasonable and unrelated to the public health, welfare, or safety. Mo.Rev. Stat. § 89.040 (2000).

The District Court 1 held, on motion for summary judgment, that the ordinance was not unreasonable or invalid for any of the reasons claimed. Plaintiffs argue that they were not allowed a fair chance to counter this point, but, as the District Court pointed out, plaintiffs themselves argued the merits of the issue in *724 their suggestions in opposition to the motion for summary judgment. We agree with the District Court. Missouri cities have broad power to enact such zoning plans. Aesthetic requirements are among the policies that cities may pursue. See Stoyanoff v. Berkeley, 458 S.W.2d 305, 310 (Mo. 1970) (per curiam).

To the extent that plaintiffs are arguing that the ordinance is unreasonable or invalid as applied to them, as opposed to being invalid on its face, the District Court held that they had failed to exhaust their administrative remedies, and that the case was, accordingly, not ripe for disposition. We agree. Mo.Rev.Stat. § 89.100 (2000). Plaintiffs could have, but did not, seek a waiver from the Trustees of the Town.

Accordingly, substantially for the reasons set out in the opinion of the District Court, we affirm. 2
