Most stormwater work focuses on how to manage stormwater generated off of impervious roadways. However, getting people to switch from driving alone to taking the bus takes cars off the road, and prevents further roadway expansion. The stormwater benefits of this mode shift is a great reason to promote transit, but the qualitative stormwater benefits are not easily available. Another facet of this work should be to understand the stormwater impacts of gasoline cars vs. hybrids vs. electric cars to see what the respective pollution generation is, with respect to stormwater.
