Editors' Summary: Pfiesteria piscicida, a sometimes toxic microorganism, is responsible for the death of millions of fish in Delaware, Maryland, North Carolina, and Virginia. Although the problem of Pfiesteria-related fish kills is associated with the Mid-Atlantic region, other toxic microorganisms have threatened fish and marine wildlife throughout the world. Scientists attribute this "global epidemic" of toxic microbes to excessive nutrient loading from nonpoint sources of pollution.

Editors' Summary: During congressional debate on CERCLA reauthorization, attention has focused on the role of states in executing the Act. Some observers of these debates have questioned the constitutionality of delegating EPA cleanup and enforcement authorities to states. In contrast, this Article argues that such delegation is permissible under the U.S. Constitution and constitutional jurisprudence. The author asserts that under the Appointments Clause, the delegation of CERCLA authorities to states would not usurp Executive Branch functions.

Editor's Summary: The exact contours of wetlands jurisdiction has been in dispute ever since the U.S. Supreme Court's decision in Solid Waste Agency of Northern Cook County v. U.S. Army Corps of Engineers. Today, the Court has been given the chance to clarify this area of law as it faces two cases dealing with wetlands jurisdiction. In Rapanos v. United States, the Court must decide whether CWA jurisdiction extends to a series of wetlands that do not abut a navigable-in-fact water. And in Carabell v. U.S.

Editors' Summary: Rather than signaling the death of private property rights, as media and the public initially feared, the Supreme Court decision in Kelo v. City of New London ushered in an era of increased state and federal protection for private property. In this Article, Daniel H. Cole examines Kelo's repercussions for urban redevelopment. He begins with a description of the case, and then examines the resulting backlash from the media and public opinion, which decried the decision as unduly expanding eminent domain powers.

Editors' Summary: In this Article, William W. Wade evaluates the conceptual measurement of economic impact within the Penn Central test for income-producing properties recently adjudicated in the U.S. Court of Federal Claims and U.S. Court of Appeals for the Federal Circuit. The discussion considers measurement of the denominator of the takings fraction related to Penn Central's parcel as a whole and whether it differs between permanent and temporary takings.

In a recent essay, David Coursen asks an important and unexamined question: Are environmental justice policies, which seek to avoid disproportionate environmental burdens on minority and poor communities, on a "collision course" with the Equal Protection Clause? In concluding that a potential collision is more illusory than real, Coursen offers a number of reasons why governmental actions to promote environmental justice have not been challenged in court and, even if they were to be, would not be subjected to strict judicial scrutiny.

Editors' Summary

The regulatory takings jurisprudence of the U.S. Supreme Court has become an ungainly body, awkward for citizens and judges to apply and challenging as well, one might guess, for the Court itself, as it continues to reshape the law to better serve its aims. One cause of this predicament: leading decisions have arisen from peculiar facts and messy procedural contexts, yielding rulings that are hard to apply elsewhere. Another cause: the divergent views of Court members on the deference properly due the work of land use regulators.

To the extent the city argues that, as a matter of law, its landuse decisions are immune from judicial scrutiny under all circumstances, its position is contrary to settled regulatory takings principles. We reject this claim of error.

Improperly planned urban development has resulted in catastrophic sprawl. The present land use zeitgeist hails urban and suburban mixed-use zoning as the solution. Mixed-use zoning combines—rather than segregates—residential, commercial, and sometimes industrial land uses, and thereby decreases housing costs, decreases commuting periods, decreases vehicle miles traveled and air emissions, increases the efficient use of land and time, and increases consumer convenience.
