Petaluma: A City on the Edge

#37, March 8, 2000

 

"It's not a river, it's a slough," my musician friend told the crowd. He was on stage at the Petaluma River Festival, getting good comedic mileage out of how Petalumans label their beloved and accursed waterway.

 

Beloved, when the salty tides offer a smooth boat route to the Bay. Accursed, when skies drop acre-feet of rain on pavement and soggy soil, and the watershed funnels it all onto the Payran floodplain.

 

I've been pondering (no pun intended) our River's multiple personalities. Last December, when the sun and moon conspired to create the highest tides in two decades, my daughter Laurel and I put our canoe into the Turning Basin and paddled upstream. Like many journeys, it began with new perspectives on the familiar: the underbelly of Washington Street Bridge, Petaluma's grain-filled skyscraper reflected against tidal slackwater. Then we entered the flood zone, paddling between mountains of earth heaved against the corrugated green iron floodwall-- the last line of defense against the next big one. Washington Creek comes in here, then Lynch Creek, both streams reaching back to the upper flanks of Sonoma Mountain.

 

Just above the confluence with Lynch is the floodgate, a huge, notched concrete wall spanning the channel. The gate marks the upper end of the flood control project, and the beginning of another realm. Iron and concrete become oak and willow. Cars and barking dogs give way to egrets and honking ducks. Laurel and I lose track of our whereabouts, then partially recover as we pass under the old railroad trestle, portal to a canyon of cascading blackberry vines. After more leisurely paddling, we reach the tip of this groping finger of the Pacific. Beaching the boat, we climb up the bank and…Surprise! The Factory Outlet Mall!

 

The sun sets, the tide turns, and we paddle home by twilight. Back through the ancient oak-tree world, through the gray gate, into the modern flood-wall world. With a radically new perspective.

 

We look at the hundreds of homes and businesses built in the river's path, and wonder about the thinking that put them so close to harm. Myopic ignorance, cynical greed, who's to say? But that was half a century ago; we know better now, yes? Today we have a flood wall, designed to protect us from the floods that race downstream to the ocean. But what are we doing to keep the flood from tomorrow coming upstream, catching Petaluma in a pincer?

 

For it was the ocean that carried our canoe so far north. This, the same ocean that will rise to greet rising levels of carbon dioxide in the atmosphere should we fail to arrest and reduce the production of greenhouse gases. If our present trend of fossil fuel consumption continues, a two foot rise in the sea level is likely within my daughter's lifetime. (Laurel is not looking forward to this, by the way.) And for those who still think global warming is an unproven theory, I ask: if a young loved one is diagnosed with a life-threatening but readily curable illness by six of seven doctors, the lone dissenter being employed by the HMO that must pay for the cure, would you withhold treatment until professional opinion is unanimous?

 

If we withhold the cure for climate fever, that twenty-year high tide will become a bi-monthly event. Combine that with the mega-storms produced by a warmer world, and our $20 million floodwall will often become a mile-long waterfall, spilling into backyards. Was this in the plan?

 

Petaluma sits on the edge of earth's one ocean; if that ocean rises up against human foolishness, we will suffer directly. But Petaluma is also at the leading edge of a revolution in the way cities behave. While we are only one vote among thousands of cities worldwide, we can cast our vote for treating climate fever now, through policies that reduce the use of fossil fuels. Our current City Council is on the right course with efforts to reduce automobile dependency. A further opportunity is coming up, as the Council considers shifting to electricity supplied from renewable sources.

 

We are on the edge Petalumans, at the gate. Time to make our choice. But not much time.
