Recents concern about the impact of global warming upon the world's climates and increased pollutiion and despoilation of natural habitats have introduced the concept of environmental and ecological sustainability as a criterion against which to judge all human activity. Sustainable design and urban and regional planning is the philosophy of designing and planning the human-built environment to comply with principles of economic, social and ecological sustainability. Originally first articulated as a criterion for urban design and planning back in the 1970's by Richard Hopper (then Hawaii's State Environmental Planning Coordinator) both in an article published in the magazine of the American Planning Association and as part of an effort he led to develop a "Quality Growth Policy for the State of Hawaii," sustainability is no longer a concept limited to the field of biology. Instead, as Hopper articulated back in the 1970's all natural and man-made systems have an inherent carrying-capacity that can either be: (1) used as a limit for growth; (2) ignored and exceeded with the consequence of thus degrading the system; or (3) expanded through new technologies and method of design and planning. As such, applying the concepts of sustainability and carrying-capacity to the design of our man-made built environment helps to protect the quality of both our man-made and natural environment.

Above is a schematic diagram of a successful municipal solid waste resource recovery/waste-to-energy plant being operated to process the waste of Fairfax County, Virginia and the surrounding jurisdictions in Northern Virginia. Ironically, Richard Hopper who had previously developed a "Quality Growth Policy" for Hawaii and applied the concept of carrying-capacity to urban planning, went on to serve as the Technical Assistance Coordinator for the Resource Recovery Division of the Office of Solid Waste of the U.S. EPA. In this role, he helped to encourage communities such as Fairfax County to implement recycling and resource recovery programs (i.e. before the federal government's recycling and resource recovery program was eliminated during the Reagan administration). This included his authoring numerous magazine articles and publications about resource recovery.

"NEW URBANISM" AND "SMART GROWTH" LAND DEVELOPMENT

"New Urbanism" and "Smart Growth" Land Development -- In the 1920's, landscape architect John Nolen designed a new suburb on the outskirts of Cincinnati, Ohio. This new suburb was named Mariemont and was meant to be a "National Examplar" of how suburbs should be designed. It was connected to Cincinnati by streetcar and by Route 50 which ran through its center. As such, it was the first transit-oriented suburb. It also was designed with all the schools and town center to be within a five or ten minute walk from all parts of the community. As such, it was designed to be promote walking and bicycling. To make the community even more pedestrian-friendly, numerous small to medium sized parks were scattered evenly throughout the community, park benches were built on street corners, streets were designed to be narrower than the typical modern suburban street to slow traffic, and large shade trees were planted between the sidewalks and streets to provide shade for pedestrians. Also, the garages of homes were set even with or behind the homes acccessed by alleyways. Through his planning of Mariemont and other subsequent communities and cities, John Nolen is credited with being the "father of modern urban planning." Ironically, the demand for housing after World War II caused the nation to abandon the planning model of John Nolen and instead to develop sprawling residential only suburbs in the model of Levittown, New York. These newer suburbs were designed for the automobile as opposed to pedestrians or mass-transit. They also abandoned the concept of integrated mixed-use as John Nolen had designed for his Mariemont community. Today, however, the 1950's style of suburban sprawl after the model of Levittown is understood to be energy efficent, wasteful of land, a contributor to air pollution and global warming, destructive of the natural environment, and destructive of of the sense of community. For this reason, urban planners and designers are increasingly turning back to the model of Mariemont as designed by John Nolen. When employed in for a suburban development, this model is typically referred to as "New Urbanism." When employed in the design of a closer-in and more dense semi-urban development, this model is typically referred to as "Smart Growth." In fact, both emphasis the same principles emphasized by John Nolen -- i.e. pedestrian oriented, transit-based, mixed-use development, with the purpose of both being to make urban and suburban development more sustainable and compatible with both the human and natural environment (as opposed to emphasizing the automobile). These two models for land development and zoning have become the primary methods of urban planners to make urban land use more sustainable. One of the first examples of "New Urbanism" is the community of Kentlands in Gaithersburg, Maryland -- while two of the more recent and best examples are Celebration in Orlando, Florida and the King Farm in Rockville, Maryland (with the latter being initially designed by Richard Hopper, who is referred to above as having initiated the concept of sustainable design in urban planning and development back in the 1970's and who then went on to also become one of the pioneers in promoting recycling and resource recovery). With respect to the concept of Smart Growth, perhaps the best known example of efforts at "Smart Growth" is Montgomery County, Maryland (with the King Farm referred to above being part of Montgomery County, Maryland's efforts to promote "Smart Growth").
