I agree, the pendulum on drainage has swung to far.
But this is their logic, that the stone will eventually fill up with fines and become impervious. The problem is they don't think it through and apply this same logic to these "new" materials AKA the pervious asphalt.

Most of the companys that make pavers are jump on the bandwagon and making pavers for the application. Although most are kind of bulky and ugly.
One thing to remember with these surfaces is they will in time need maintence. Which is something to consider when figuring out what type of surface to consider.
For instance ,the concrete and pavement even needs to be "cleaned" And the process for this is by blasting water into the surface and vacuuming it out. Not very enviormently friendly if you need to use cleaning agents and then what do you do with the water after you have sucked it back out of the pavement?
I just went to a seminar for the Techo-bloc pavers they just came out with.
Pretty good stuff for the person that falls under the CSPA to meet some of the restrictions.
