Some of the smartest, most innovative solutions for building thriving and sustainable communities in the Northwest are, at present, simply illegal.
Even the best-intended rules to protect people and shared assets can become outdated. From business strategies (think buggy whips and typewriter ribbons) to the stuff forgotten in the back of your fridge, almost everything has an expiration date. Luckily, weeding out the counterproductive rules rendered irrelevant by time can have a big impact—making it easier and cheaper to do the right thing.
Take the problem of the urban stormwater runoff that threatens the health of Puget Sound and other waterbodies throughout the Northwest. Low Impact Development (LID) solutions—including such strategies as rain gardens, street-side swales, porous pavement, and green roofs—can treat stormwater more effectively, and for less money, than the costly “hard” infrastructure of downspouts, pipes, and sewers. Yet many development codes mandate the more-expensive, less-effective plumbing solution. If only codes would allow LID as an alternative, the region could see a proliferation of lower-impact techniques that could spare government coffers in lean times, and give developers and homeowners a financial break—even while providing cleaner water and patches of urban habitat.
The culprit in each of these stories is the most mundane of villains: the rain. As rainwater streams off roofs and over roadways and landscaped yards, it mixes a massive toxic cocktail. It scoops up oil, grease, antifreeze, and heavy metals from cars; pesticides that poison aquatic insects and fish; fertilizers that stoke algal blooms; and bacteria from pet and farm-animal waste. A heavy rainfall delivers this potent shot of pollutants straight into streams, lakes, and bays—threatening everything from tiny herring to the region’s beloved orcas to our families’ health.
I have always been eager to understand the natural and human capital of the Pacific Northwest, the attributes of people and place that shape the possibilities of our home. I tend to frame sustainability in these bioregional terms.
Stormwater obviously causes problems for the environment and infrastructure, washing away salmon eggs in torrents of runoff and flooding basements. But does it threaten human health as well? You bet it does, and in ways that might surprise you.
