SUPREME COURT OF THE UNITED STATES

Syllabus

DOLAN v. CITY OF TIGARD

certiorari to the supreme court of oregon

No. 93–518. Argued March 23, 1994—Decided June 24, 1994

The City Planning Commission conditioned approval of petitioner Dolan's application to expand her store and pave her parking lot upon her compliance with dedication of land (1) for a public greenway along Fanno Creek to minimize flooding that would be exacerbated by the increases in impervious surfaces associated with her development and (2) for a pedestrian/bicycle pathway intended to relieve traffic congestion in the City's Central Business District. She appealed the Commission's denial of her request for variances from these standards to the Land Use Board of Appeals (LUBA), alleging that the land dedication requirements were not related to the proposed development and therefore constituted an uncompensated taking of her property under the Fifth Amendment. LUBA found a reasonable relationship between (1) the development and the requirement to dedicate land for a greenway, since the larger building and paved lot would increase the impervious surfaces and thus the runoff into the creek, and (2) alleviating the impact of increased traffic from the development and facilitating the provision of a pathway as an alternative means of transportation. Both the State Court of Appeals and the State Supreme Court affirmed.

Held: The city's dedication requirements constitute an uncompensated taking of property. Pp. 8–20.

(a) Under the well-settled doctrine of ``unconstitutional conditions,'' the government may not require a person to give up a constitutional right in exchange for a discretionary benefit conferred by the government where the property sought has little or no relationship to the benefit. In evaluating Dolan's claim, it must be determined whether an ``essential nexus'' exists between a legitimate state interest and the permit condition. Nollan v. California Coastal Comm'n, 483 U. S. 825, 837. If one does, then it must be decided whether the degree of the exactions demanded by the permit conditions bears the required relationship to the projected impact of the proposed development. Id., at 834. Pp. 8–10.

(b) Preventing flooding along Fanno Creek and reducing traffic congestion in the District are legitimate public purposes; and a nexus exists between the first purpose and limiting development within the creek's floodplain and between the second purpose and providing for alternative means of transportation. Pp. 11–12.

(c) In deciding the second question—whether the city's findings are constitutionally sufficient to justify the conditions imposed on Dolan's permit—the necessary connection required by the Fifth Amendment is ``rough proportionality.'' No precise mathematical calculation is required, but the city must make some sort of individualized determination that the required dedication is related both in nature and extent to the proposed development's impact. This is essentially the ``reasonable relationship'' test adopted by the majority of the state courts. Pp. 12–16.

(d) The findings upon which the city relies do not show the required reasonable relationship between the floodplain easement and Dolan's proposed building. The Community Development Code already required that Dolan leave 15% of her property as open space, and the undeveloped floodplain would have nearly satisfied that requirement. However, the city has never said why a public, as opposed to a private, greenway is required in the interest of flood control. The difference to Dolan is the loss of her ability to exclude others from her property, yet the city has not attempted to make any individualized determination to support this part of its request. The city has also not met its burden of demonstrating that the additional number of vehicle and bicycle trips generated by Dolan's development reasonably relates to the city's requirement for a dedication of the pathway easement. The city must quantify its finding beyond a conclusory statement that the dedication could offset some of the traffic demand generated by the development. Pp. 16–19.
