Stormwater Lecture - Building a Better Bend
In designing successful cities, the economy, the human community and the environment ought to thrive together. Porous pavements are a multi-functional at-source solution that fits in exactly with todays interest in dense urban redevelopment and sustainability.
Porous pavements are not distinct, separate stormwater facilities: they are a new way of building cities, which restores environmental processes at the source, within structures that are built as part of the urban program. Their potential application is vast, because pavements are two thirds of the constructed surfaces in most urban districts: they are responsible for two thirds of excess stormwater runoff, two thirds of the temperature increase in the urban heat island, and essentially all of the urban water quality pollutants. Since 1996, Prof. Ferguson has interviewed 250 porous pavement experts around the world, reviewed 1,000 technical articles and reports, and surveyed firsthand 450 installations of all kind of porous pavements in all parts of North America. His book Porous Pavements was published in 2005. Scientific monitoring has produced quantitative, observed, documented facts that cast aside old rumors and speculations.
Case studies in the arid West and throughout North America illustrate porous pavements applications on clay soil and under freezing winter conditions. They have been installed in city streets, at art museums, factories, and offices, and in new communities. The correct ways to select, design, install, and maintain porous pavements are known. Properly installed and maintained, they absorb rain water rapidly; oil biodegrades and ceases to exist as a water quality pollutant. They give urban trees viable rooting space, allowing them to grow to full size, providing shade, cooling, air quality, and outdoor architecture. By offering colors and patterns, alternative paving materials articulate and reinforce the design of urban spaces. They can reduce development cost by reducing or eliminating separate downstream stormwater facilities. They release infill development sites for full urban development, reducing the demand for suburban sprawl.
This new technology integrates the urban environment. There does not need to be a dichotomy between cities and the environment. We do not need to say that cities are sacrificial. Today, in a single urban space, there can be a living tree canopy above, a living rooting zone below, all the economy and land use of a city at the surface, absorption of stormwater, and restoration of natural processes.
