Otay Mesa Property, L.P. v. Department of the Interior
Otay Mesa Property, Rancho Vista Del Mar, and Otay International own several parcels of undeveloped land in the Otay Mesa area of San Diego County. The U.S. Fish and Wildlife Service designated a significant portion of this land as critical habitat for the Riverside fairy shrimp, a small freshwater crustacean listed as “endangered” under the Endangered Species Act. While the ESA requires the designation of critical habitat, it also requires that the designation occur on the basis of the best available scientific data and with consideration of economic and other relevant impacts. Areas may be excluded from designation if the benefits of the exclusion outweigh the benefits of the designation, unless the exclusion will result in the species’ extinction.
The Service designated thousands of acres of critical habitat for the Riverside fairy shrimp in five Southern California counties, including a portion of Otay Mesa’s property. At the time of the listing, the property did not contain the physical and biological features necessary to the conservation of the shrimp and the Service never investigated the economic or other effects the designation would have on the productive use of private property. In the trial court, on cross-motions for summary judgment, PLF submitted an amicus brief argues that the Service failed to conduct a proper analysis of the economic consequences of designation, in violation of several key statutes.
