New "Must-Read:" Permeable Pavements Book

It's here, it's here! 

After much anticipation, the thirty one members of the Permeable Pavement Task Committee have finally released the Permeable Pavements book.  This 262-page document provides a summary of typical permeable pavement systems and includes pavement performance data, design and construction considerations, factors affecting maintenance, and even a chapter on emerging technologies.  

Though increasingly used on our sidewalks, roadways, parking lots and even play areas, there are still only a few agencies with standards that can be used for the design of pervious pavement systems. This document is a comprehensive resource providing technical guidance for this important stormwater management BMP. It's a must read for "engineers, planners, landscape architects, municipalities, transportation agencies, regulatory agencies, and property owners."

The book's publication was sponsored by the Low Impact Development Committee of the Urban Water Resources Research Council of the Environmental and Water Resources Institute of ASCE. Published by the American Society of Civil Engineers.

Look for the contributions of a few of your favorite SvR authors and special thanks to the hardworking editing and review team of Kelly Lindow, Bethany Eisenberg and David Smith who spent many late nights compiling, editing, reviewing, and cat herding to get this publication out the door!

"Maps codify the miracle of existence.”

In his biography of the Flemish cartographer Gerard Mercator, the English writer and geographer Nicholas Crane notes that "maps codify the miracle of existence." Or, as the author Tony Horowitz says, "“I am an agnostic on most matters of faith, but on the subject of maps I have always been a true believer. It is on the map, therefore it is, and I am.” We agree. Maps are one of those endlessly fascinating phenomena. Yet in this age of easily-accessible, easily-updated digital maps, it takes a unique example of the cartographer's craft to really pull us in. Below are a few examples of maps that we've found particularly engaging; click on any of the images to learn more.
