Whether the Board's refusal to rezone the Allman property from RE-1 was arbitrary and without a reasonable or substantial relation to the public health, safety, morals, or general welfare.
Holding
Yes. The Board's reaffirmation of the RE-1 classification was arbitrary and capricious, so the classification was invalid as applied to Allman's property.
Reasoning
A local governing body's zoning action is legislative and begins with a presumption of validity and reasonableness. A challenger bears the burden to produce probative evidence that the action is unreasonable. Once that evidence is produced, however, the locality must offer enough evidence of reasonableness to make the issue fairly debatable; otherwise, the legislative presumption cannot sustain the action.
Allman met that burden. The County's own Upper Potomac Master Plan called for a suburban-density cluster that included the tract, and the proposed PDH-3 density conformed to that plan. Although a master plan is advisory rather than itself a zoning ordinance, it strongly undercut the claim that a higher-density residential use was inconsistent with the County's planning judgment.
The record also showed that the tract was not an isolated rural parcel. It lay near higher-density development in Hiddenbrook, Herndon, Sterling Park, Reston, and the nearby Clinch tract. Moreover, the County favored planned development and had encouraged Reston's extensive growth, even though Reston used the same general public facilities that the Board said could not accommodate Allman's much smaller project.
The Board's facilities rationale did not make its decision fairly debatable. Evidence permitted the trial court to find that water and sewer capacity were adequate and that roads, schools, fire protection, and other services either existed or would become available as the project developed. The County had no policy requiring every public facility to be completed before higher-density zoning could be approved, and its own supervisor recognized that infrastructure ordinarily follows development and the demand for services.
Most importantly, the Board treated similarly situated landowners differently without a meaningful justification. It approved the nearby Clinch rezoning from RE-1 to R-12.5 shortly after rejecting Allman's request, although its zoning official acknowledged that Clinch presented the same County concerns and that Allman's planned development was more favorable than a conventional subdivision in cost-benefit terms. The Board's assertion that the Clinch approval was merely a mistake did not supply a rational basis for denying Allman equal treatment.
This inconsistent and discriminatory pattern established arbitrariness. Because discriminatory zoning action is capricious and lacks a reasonable or substantial connection to public welfare, the Court affirmed the trial court's conclusion that RE-1 was invalid as applied to the Allman tract.
