The nexus between transportation and land use.

Traffic Signal Synchronization, Ctd.

I was recently quoted in an article on traffic signal synchronization – an ongoing project in Minneapolis right now. I have a contrary view to conventional wisdom on this topic as I have been quoted in the article and expressed in greater detail here.

Communities like traffic signal synchronization because it is smart technology that can reduce congestion and increase traffic flow without making any geometric changes to the roadway system. My argument is that these technologies work a little too well – they actually create induced demand  which in the longer term leads to more congestion and air pollution and poor land use decisions. I’ll stand by my quote in the article in that traffic signal synchronization is a solution that becomes a victim of its own success.

The Suburban Experiment, Explained

I have been an enthusiastic adopter of the term “suburban experiment” after having following the magnificent work that Strong Towns does up in Minnesota. But it came to my attention that I have not fully explained it and applied it here in Chicago.  So, I’d like to take a step back. Of course, since I did not invent the term, it’s best to direct you to the primary source. Chuck Marohn’s seminal articles on the suburban experiment note that:

“our post-World War II pattern of development — operates like a classic Ponzi scheme, with ever-increasing rates of growth necessary to sustain long-term liabilities.”

Meaning essentially that this form of development cannot fiscally sustain itself over more than one life cycle without  more growth to pay off previous liabilities.  Essentially, all of the infrastructure that supports the inefficient development pattern that is modern suburbia, the huge investment in roads and utilities to support sparsely dense areas, does not make economic sense after one life cycle.

We’re already seeing this today.

You know we can’t support our towns and cities when roads turn to gravel, when bridges collapse, streetlights get turned off and park districts, schools and municipal budgets are slashed despite ever rising taxes. It means that we’re not allocating our resources efficiently, that maybe the great wealth this country has had has been spent towards a pattern of development that just cannot sustain itself.

 

 

 

Competition

There is nothing wrong with friendly competition. I laughed when I saw this image and read this article on Streetsblog.rahmfeud

But the truth of the matter is that this makes a lot of sense. I’m talking about transportation investment in cities. It’s been clear for some time now that the suburban experiment is coming to an end, that we need to reinvest in our cities. Now, I am a Chicagoan and I’m not necessarily a big fan of Rahm (who eliminated the planning department at City Hall!). But, he has done some very innovative, urban friendly things that are paying off. There is a reason that downtown Chicago has attracted corporate investment the past couple of years. One example of smart transportation investments, alluded to here in the Streetsblog article, is the Dearborn protected lanes.

I’m not sure whether we’re better off in the long run stealing jobs from other cities. But, then again, I’m not sure I’d categorize it as stealing. When you build infrastructure in the right way, the economic rewards will come.

 

Weak Illinois Towns

So I will admit: I am out of my league when it comes to municipal finance. As a transportation planner for a major transit agency in Chicago, I am not expected to know much about municipal finance in my professional line of work. But I do know a bit about Strong Towns. And after recently purchasing Charles Marohn’s guidebook, Thoughts on Building Strong Towns, I feel educated enough to point out what makes a strong town and what does not. Which brings me to the point at hand.

The Chicago Tribune (behind free registration and/or paywall) ran a rather insightful, if completely depressing, article on the ability of towns in Illinois to borrow incredible amounts of money with very little state (or even local) oversight:

That’s because Illinois law allows even the smallest of towns to tax, spend and borrow like the biggest of cities. Municipal advocates insist that home-rule power has largely improved towns, but the Tribune found suburb after suburb has gone deep in the hole over projects ranging from buying a roller rink to building condos — ventures far beyond the basics of building roads and sewers…

Critics say Illinois’ loose rules invite those dangerous conditions by eliminating fundamental checks and balances: Those borrowing the money — residents — may have little chance to vet the plans. And those lending the money — investors — may care little about the details, so long as the town leaders agree to boost taxes as high as needed to pay off the debt.

The ability of Illinois towns to borrow unseemly amounts of money is given to them via “home rule”. Home rule shifts many decision-making powers assumed by the State to the municipal corporation. In Illinois, it is triggered in one of two ways: either the municipality has grown to a population of 25,000 or greater in which home rule status is automatically acquired OR a municipality assumes home rule powers through public assent via referendum. Currently, over 70% of Illinois’ population lives under home rule status.

The issue with home rule status in this case is that the municipality has the ability to borrow large sums of money without a cap, without direct voter approval, and without state oversight. While local control is seen by many as a wonderful thing, when there is no oversight, these powers can lead to abuse. And they have:

  • Officials in south suburban Markham raised sales and property taxes while borrowing $20 million mostly to buy a roller rink and build a senior apartment building — the latter named after the mayor.
  • Northlake borrowed $14.5 million to build a 60-unit condo building that opened in 2009. The town cut prices and even helped finance mortgages, but about 20 units remain unsold.
  • Country Club Hills built an amphitheater that doesn’t make enough to cover debt payments and typically loses $300,000 to $1 million a year, depending on what expenses are counted.

These are the things that make weak towns. In terms of the “Growth Ponzi Scheme” that Marohn has described, this is it.

I see the suburban experiment failing all around. From municipalities that cannot afford their poor development investments to crumbling infrastructure to raising the ability to borrow ever more amounts of money for no productive use, it is clear that our society cannot function like we once did. Sadly, it is articles like this that are only the beginning of our fiscal woes.

Urbanism and Resort Communities

I’ve spent the better part of last week in Sarasota, Florida, on Lido Key with my family to attend a wedding for my sister-in-law. Much has been written about sprawl throughout Florida or the housing crisis. What interested me was the urbanism I had found near the resort I stayed at, most unexpectedly.

St. Armand's Circle, looking west towards Lido Key.

The urbanism I’m speaking of was found on Lido Key and neighboring St. Armand’s Key. John Ringling (of Ringling Bros. fame) and Owen Burns purchased Lido Key, St. Armands Key and neighboring Bird Key in the 1920s and began a development scheme which eventually failed in the 1929 stock market crash. St. Armand’s Key has in its center, Harding Circle, shopping district oriented around a beautiful roundabout, which has been recognized on the National Register of Historic Places.

In the pictures, you may notice several features celebrated in new urbanism and planning circles alike: roundabouts, landscaped sidewalks and pedestrian treatments, all imposed on a grid street pattern.
These types of urban environments in resort communities are few and far between. I treasure spending time in these environments.

See how the landscape treatments separate cars from pedestrians? This allows more intensive pedestrian uses of the sidewalk like this cafe. Source: winterwhiteiris
