Pavement (not the band)

In his last post, hubby mentioned the permeable pavers under our carport, and I’d like to talk a little more about them.
Driveways, sidewalks, and roads tend to be solid surfaces, right? Unfortunately, there’s no way rain can seep through that concrete back into the groundwater table, getting purified along the way. Instead, it hits the pavement and moves super fast to the stormwater drain, causing erosion and carrying sediment, oil, fertilizer, and pesticide back to our streams.

Just like the rain gardens I mentioned last week, permeable pavers slow the speed of stormwater and collect it in vegetated pockets. Naturally occurring micro-organisms live in these spaces where they digest car oils and other nasties, leaving little but carbon dioxide and water behind. 

  
I won’t lie, permeable pavers cost about 1.5x the price of pouring a concrete driveway. But the price tag was still low enough that the project was doable, and I have to believe that clean water in the Chattahoochee is worth every penny.

Can’t resist, here’s a little Pavement for your auditory pleasure.

    I’d add only that even though the materials are more expensive, going with pavers over concrete made this a project we could do ourselves without hiring a contractor. So we actually saved money, but invested a lot of elbow grease.

    We thought about doing something like this with pavers for the driveway that leads back to our barns but it was cost-prohibitive. It would be nice to have grass all the way back. Instead, we’ll end up dumping loads of crushed limestone (still permeable, right?). We need something to make the soil stable enough to be driven on after a rain.
