Also check out a companion blog post from Vince Patton, exploring the math of stormwater management '37 inches = 86 billion gallons' : "Portland gets about 37 inches of rain each year. That adds up to 86 billion gallons of water falling on our heads, grass, driveways, parking lots, roofs and trees. The city’s big headache is that we’ve paved over so much of metropolitan Portland that most of that water is running down into the storm sewers."
