People are moving from rural to urban landscapes at unprecedented rates. Cities are complex collections of infrastructure elements which, when they interact with each other, the local environment, and human social structures, exhibit the emergent properties of ecological systems. We contend that the best path toward urban sustainability lies within the understanding of urban infrastructure as an "Infrastructure Ecology." This new discipline will re-engineer urban infrastructures to maximize the production of comfort and wealth, while reducing the system-wide use of resources and generation of wastes, and increasing their sustainability and resilience to shocks.

Messner Project Presentations
Many parrallels have been drawn between the current financial crisis and the Great Depression of the 1930's. We can also draw some lessons from how the U. S. federal government leveraged limited funds on large infrastructure projects to rebuild economic vitality. Encouraged by Mr. Michael Messner, Tech alum, partner of the Seminole Capital Partners and advisory board member of the School of Civil and Environmental Engineering, this project was conducted to explore how this might occur with the current and forthcoming rounds of federal stimulus funds.
