Dolan v. City of Tigard

Dolan (plaintiff) sought a permit from the City of Tigard (defendant) to expand her store and pave her gravel lot, which would increase impervious surface and storm runoff. The city granted the permit on the condition that Dolan dedicate the portion of her property within the floodplain as a public greenway and dedicate an adjacent strip for a pedestrian and bicycle pathway meant to offset traffic from the larger store. State administrative and judicial bodies upheld the conditions, and the United States Supreme Court granted certiorari.
