Climate change will have profound and diverse impacts upon infrastructure throughout the United States, including transportation infrastructure. Rising sea levels, stronger storm surges, more severe flooding, land subsidence, soil erosion, melting permafrost, and more frequent freeze-thaw cycles will all strain our already aging, deteriorating roads, bridges, and ports. The American Society of Civil Engineers has consistently given the country’s infrastructure a D or D+ on its annual report card since 1998, and the US slipped from fifth place in 2002 to 24th by 2011 in World Economic Forum’s transportation rankings. Throw in profound and unpredictable changes to the climate that facilitated the rise of human civilization, and you have a recipe for disaster.
It is for this reason that the President Obama’s administration has attempted to drag the federal government into the 21st century on climate change planning, despite considerable institutional inertia, not to mention stalwart opposition from Congressional Republicans and special interests. Just last week, the President issued an executive order requiring all federal agencies to include long-term sea level rise projections during the siting, design, and construction of federal projects. Planning for such changes and the threat of 100- and 500-year flood events, which will become drastically more frequent in a greenhouse world, will be of vital importance for the US Department of Transportation. Critical institutions are already at risk from near-term climate change. Parts of Oakland International Airport, for instance, could wind up under water during the daily high tide if sea levels rise just 16 inches.
But, given the complexity of our federal system of government and the aforementioned institutional inertia, the administration’s actions will take time to trickle down to the state and local level, where many of the daily decisions on transportation infrastructure construction and maintenance occur. While this fragmented structure has enabled some progressive state and municipal governments to take steps to combat climate change in the absence of meaningful legislation from Congress, it can also create a highly uneven system in which certain locales are far more inclined to incorporate climate change considerations in transportation planning. Given the fact that the roads, bridges, and ports we build today will likely still be in operation 30-50 years from now, each day that we delay increases our adaptation deficit – that is, the gap between our current level and an ideal level of adaptive capacity to a changing climate.
To demonstrate this uneven level of adaptation, consider the different approaches to climate change planning from the Minnesota Department of Transportation (MnDOT) and the Ohio Department of Transportation (ODOT). This week, Minnesota Public Radio is featuring a series on climate change in the North Star State. An article this morning discussed how the state has adapted to more severe rainfall events in recent years.
In all three cases, whether officials say it in so many words or not, they are adapting their cities’ infrastructure to a changed climate, one that has been dumping more rain and bigger rains on Minnesota.
Warmer temperatures have an impact on infrastructure as well – more freeze-and-thaw cycles mean more potholes, for example. But because roads require relatively constant maintenance, road planners can adapt to a changing climate on the fly.
Not so with storm and wastewater systems, which are built to last as long as a century. That, say urban planners, is where the real challenge lies, and it is where some Minnesota cities have been focusing their efforts to adapt to climate change.
As the article notes, severe rain and flash floods have taken a drastic toll on infrastructure, including transportation systems, in recent years. Fortunately for Minnesotans, MnDOT has been leading the way in the effort to incorporate changing precipitation patterns and flood risks into planning. The agency recently completed an assessment of climate change risks to infrastructure in two districts, District 1 and District 6, which are located in the northeast and southeast portions of the state, respectively. In the introduction to the assessment, MnDOT writes,
Recognizing this, MnDOT planners and engineers have long considered minimizing the risk of flash flooding in the siting and design of the state’s roadway network. However, as has been the standard practice worldwide, they have traditionally assumed that future climate conditions will be similar to those recorded in the past. Climate change challenges this assumption and calls for new approaches to understanding vulnerabilities across the highway system and at specific transportation facilities so that appropriate actions, adaptations, can be taken to minimize expanding risks.
This project…represents a starting point for developing these new approaches. The focus of this pilot study is on flash flooding risks to the highway system. While flooding is not the only threat to the state’s highway system posed by climate change, it is likely to be one of the most significant and has already caused extensive disruptions to the transportation system in many areas.
If only Ohio had taken such a proactive approach to this issue. To be fair to ODOT, the agency does appear to be considering climate change in its planning process. There is a section devoted to the issue in Access Ohio 2040, the state’s long-term transportation planning vision. Perhaps strategically, the document refers to it as “climate variability” and completely bypasses the question of what is causing climate change. Now, the supplement to this section does touch on the fact that greenhouse gas emissions, including those from transportation, are driving the observed changes, though it does so somewhat halfheartedly. And then there’s the presentation on climate change infrastructure vulnerability that seems more focused on the potential benefits for the state from altering our extant climatic systems.
But, at least ODOT appears to have faced up to the issue. Access Ohio 40 calls for the state to complete a Statewide Climate Variability Study “within the next two years.” If the state meets this metric, the study should be finished by summer 2016, leaving the state roughly 18 months behind MnDOT. Now, I should note that, unlike ODOT, MnDOT’s assessment was one of 19 pilot projects funding by the Federal Highway Administration through its 2013-2014 Climate Change Resilience program. Then again, states, metropolitan planning organizations, and other entities had to actually apply to secure FHWA funding. I can find no evidence that Ohio bothered applying. Additionally, I have searched through the State of Ohio’s FY 2014-2015 transportation budget, and I find no evidence that the legislature has ponied up the $250,000-500,000 that ODOT stated it would need to complete its climate variability assessment. So I question whether Ohio is on track to finish the assessment by next summer.
And, even if ODOT has made some commitment to climate change adaptation at the strategic level – a highly dubious proposition – there is absolutely no evidence that this commitment has worked its way down to the project level. Consider the Opportunity Corridor, one of the largest projects currently being funded in the state. A handful of individuals and organizations submitted comments to ODOT’s Draft Environmental Impact Statement (DEIS) on the project, imploring the agency to take climate change into account. Here’s how ODOT responded in its Final EIS:
[I]t is analytically problematic to conduct a project level cumulative effects analysis of greenhouse gas emissions on a global-scale problem… Because of these concerns, CO2 emissions cannot be usefully evaluated in the same way as other vehicle emissions. The NEPA process is meant to concentrate on the analyses of issues that can be truly meaningful to the consideration of project alternatives, rather than simply “amassing” data. In the absence of a regional or national framework for considering the implications of a project-level greenhouse gas analysis, such an analysis would not inform project decision-making, while adding administrative burden.
In other words, we think your request is stupid and a waste of time, so nope.
ODOT does not operate in a vacuum. I’m sure there are a lot of good civil servants trying their best to meet the needs of Ohioans at the agency, but its direction is ultimately shaped by the elected officials in power in Columbus. Governor Kasich may at least pay lip service to climate change, but he has shown no inclination to actually act on the issue. Quite the contrary – he is responsible for signing SB 310 into law last June. Attorney General DeWine, for his part, is currently suing the EPA to stop its efforts to regulate greenhouse gas emissions.
And then there’s the GOP-dominated statehouse. The only reason Senator Bill Seitz will ever leave the legislature is through term limits, regardless of how many bombs he tosses about enviro-socialist rent seekers or the Bataan death march. And Senator Troy Balderson, the person who sponsored SB 310 and serves on the committee that regulates electric utilities, was blissfully unaware of the EPA’s plan to regulate coal-fired power plants a year after it was announced. It’s not exactly a shock that ODOT is a laggard here.
Those of us in Ohio who want an agency that is responsive to our desires to create an equitable, low-carbon, fiscally responsible transportation system need to keep pressuring ODOT, but we also need to win elections. Until then, our civil servants and public officials will keep their heads firmly lodged in the sand.
