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.

Smart Growth admits of no clear definition. It provides a popular label for a growth strategy that addresses current concerns about traffic congestion, disappearing open space, nonpoint source pollution, the high cost of housing, increasing local property taxes, longer commutes, and the diminishing quality of community life. To accomplish smart growth, government must take two related actions. The first is the designation of discrete geographical areas into which private market growth pressures are directed.

In the west Chicago suburb of Sugar Grove—population 4,000, twice what it was 10 years ago—new large-lot developments spread spider-like from the downtown public library, police station, and village hall out into open farmland. The village has no sizeable employers or large shopping centers, and has limited recreational facilities. All those things are available close by in other suburbs and, of course, in the city of Chicago. After elementary school, children travel to neighboring suburbs for high school.

Timothy S. Bishop and Cristina C. Tilley, litigators in the Chicago office of Mayer, Brown, Rowe & Maw, offered up a Dialogue in the July 2002, issue of the Environmental Law Reporter News & Analysis entitled Smart Growth or Dumb Bureaucracy? They didn't cite the Article I wrote with my law partner of 25 years, Gurdon H. (Don) Buck, Smart Growth, Dumb Takings, which was also published in this august periodical. I don't think we own the form of the title beginning with "Smart" and linked to "Dumb," but it would have been nice to have been recognized.

The preservation of open space has captured the public's imagination. Taxpayers are lining up to vote in favor of referenda authorizing their local or state governments to borrow funds to purchase open land or its development rights. Environmental groups are forming coalitions to support public acquisition of open space and the adoption of laws regulating development in and around open lands. Opponents of urban sprawl target the loss of open space as one of the major impacts of runaway development.

Through the post-World War II era the U.S. Congress, by an incremental process of experimentation and error, developed the knowledge and experience that led to the imposition of individual permits based on uniform technology-based effluent limitations to regulate industrial water pollution. The resulting permit system has gradually reduced the amount of industrial pollution that enters our national waterways.

Agricultural biotechnology has generated much debate about the environmental consequences of field trials and commercialization of transgenic crops. Thus far, the debate has focused on opponents' claims of alleged risks presented by transgenic crops and the proponents' responses to those asserted risks. To date, three issues have dominated the debate:

. the risk of gene flow;

. the risk of weediness; and

. the risk of insect-resistance.

In recent years, the western states have often struggled with the federal government over control and management of natural resources, particularly water. For its part, federal law defers to states in many matters of water resource allocation.
