We're working on a project right now. At our office we have a fair-sized parking area that we want to redo in pervious pavement, and we want to use it as an example for developers. We can prove that using the pervious pavement, which is a lot more expensive, may negate the need for stormwater ponds, because you're not necessarily taking away the whole drainage area. So that's one example we're getting a lot of interest in.
It's unfortunate that everything that's really good for the environment costs a lot. Everything that we buy that's really good and works well is more expensive than the stuff that's not the best for the environment. When pavement costs $30 a yard and the cost of this pervious material is $80 a yard, that's a hard sell, but we are getting a lot of interest, and we hope that it will be a marketing tool for developers in the future.
