So you're thinking about using porous pavement? This session is designed to review the emerging trends, options and maintenance considerations for greener streets and non-motorized facilities.

Case studies will include current information gleaned from new data from the recent increase in porous asphalt streets. Presenters will review appropriate cost comparison methods to allow you to provide decision makers with the total cost information, not just a comparison of pavement and aggregate material costs. The impact of additional excavation, reduced stormwater management, less winter maintenance, and other items will be reviewed.

We will show you just how much impervious surface a Midwestern City of 115,000 owns, and why porous pavement is a critical strategic tool to have in your toolbox. In addition, presenters will provide suggestions for identifying candidates, early in the project inception phase, preferably during capital improvement planning.

While there is a wealth of information available, this session will summarize where other agencies have been with the use of porous asphalt and porous concrete for streets, not just parking lots, with several case studies on post construction performance.

After viewing this session, participants will be better able to:

Evaluate alternative strategies for dealing with runoff in the right of way
Calculate the strategic risk in utilizing porous surfaces
Explain the challenges and benefits of using porous pavement
