OP-ED: Do Green Streets Actually Work for Stormwater Management? – reflections by Jonathan Page on eco-region differences

Her comments were a lead into an overview of the function and benefits of permeable interlocking concrete pavement. Benefits include a reduction in the volume of rainwater which has to be handled by infrastructure systems.
