$5 could be yours

It’s morning in St Louis, and we’re getting ready to talk with some of the movers and shakers in the world of riverfront greenways. While preparing, we ate at a greasy spoon where Jimmy Kimmel was on the teevee talking about his daily cross-country flights for this week’s double-hosting duty. Yikes. On a side note, […]

… we’re off to St. Louis

Despite the whirlwindiness of our visit to Dubuque, Sarah and I feel like we got a good picture of the work that’s going on there. It helped to have a view from the country’s shortest, steepest railroad: We’ll write about all of this in more detail later in the fall. But for now, it’s off […]

Exploring Dubuque by boat

What floats our boat? Um, we’re not quite sure, but that didn’t stop us from taking the helm like two river rats making our way downstream. Thanks to the (very Dubuque) hospitality of Trish McDonald and her "chick boat" Doris Day, we were fortunate enough to spend the day out on the Mississippi River. Trish […]

Granted, it’s early yet

Just met with Laura Carstens, planning services manager for Dubuque. The money quote: “For years, we turned our back on the river. Now we’re making it our front door.” Later today, Sarah and I will get out on the river for the first time. The tourist riverboat stopped running this weekend because the weather turned, […]

Exploring Dubuque’s riverwalk, tourist-style

While Katharine spent the day getting free lunch and talking to city planners, I spent my day exploring what, exactly, all those city planners have spent all their time planning. Namely, the America’s River project I mentioned earlier today. I toured the National Mississippi River Museum & Aquarium with Teri Goodmann, the director of national […]

A meeting of the minds in the Masterpiece on the Mississippi

There’s no free lunch — unless you happen to be a Grist reporter crashing a sustainability conference in Dubuque. I showed up, hungry, for a 12 p.m. presentation by City Manager Mike Van Milligen that was kicking off a three-day Sustainable Design Assessment Team visit. I was rewarded not only with more inspiring examples of […]

A morning meeting with the mayor of Dubuque

I wish I could tell you I wrote this from atop a log raft while floating down the Mighty Mississippi, but sadly the wifi access out there ain’t so mighty. Instead, I’m sitting at a table inside the Grand Harbor Resort and Conference Center complex, which is part of the $188 million riverfront development project […]

Even the greenest suburbs can’t touch low urban emission rates

Last Sunday, the Washington Post published a piece by Joel Kotkin and Ali Modarres which sought to debunk the ideas that dense urban areas are greener than their suburban counterparts and that encouraging dense growth might play a significant role in reducing America’s carbon output. The piece was wrong or misleading on practically every point, […]

Bikeways pay for themselves

A decade ago, we wrote that the bicycle is one of the world's seven everyday wonders because it's so simple, effective, affordable, and pollution-free. To that list, we might have added "enriching."

Bicycling for transportation pumps money into local economies. Bikes are wheels of fortune. (Thanks to Flickr photographer hanbyholems for the picture to the right.) If your community spends money building bikeways, you and your neighbors will cycle more. Your cycling will put extra money in the local economy. (I'll explain how in a moment.) The extra money will make the community rich enough to pay for more bikeways. More bikeways will induce more cycling, and the virtuous circle will continue.

Let's break the process into steps.

Building bikeways costs money.

Bikeways are cheap, especially compared to roads and trains, but they're not free. In the Puget Sound area, construction can easily cost more than $1 million per mile for a new trail or lane -- not counting land. Seattle's 10-year Bicycle Master Plan sketches a citywide network of cycling routes estimated to cost about $240 million. Retrofitting all of Cascadia's communities for Bicycle Respect -- integrated systems of separate, signaled bikeways as found in parts of northern Europe -- would cost billions of dollars. (Sort of like RTID/ST and Pacific Gateway.)

Commuters in Seattle avoid congested roads by driving less

Apparently, folks in Greater Seattle are responding to congestion by ... driving less! Which is, quite literally, no surprise at all. A comprehensive study of transportation patterns in cities across the globe found that high levels of congestion are linked with low overall energy consumption. When roads get congested, people adjust, and find alternatives to long, time-consuming commutes.

And that's what seems to be happening in Seattle. Highway congestion has grown in the region, as it has virtually everywhere in the U.S. But per-capita car ownership is on the decline, and total vehicle miles per capita has begun to level off. More importantly, the article cites evidence that growth management laws have concentrated much of the region's recent growth into already-urbanized areas -- the sorts of places where people don't have to make long treks to jobs or stores.
