Something to Think About

Moin Kondri’s guest column in the Seattle Post-Intelligencer is worth a quick read. Kondri, a geologist, writes on the cost of rainwater in urban environments: it’s free until it hits the ground. Largely, he argues, this is due to old, hasty designs that called for hard armor urban stormwater systems. The runoff has proved to be too much. Softer, smarter drainage–greenroofs, porous pavers, etc.–must be incorporated.
