On Monday, President Joe Biden signed the into law鈥撯�搕argeting roughly $1.2 trillion to shore up the nation鈥檚 aging, sagging and crumbling roads, bridges and other infrastructure. According to estimates from the White House, Colorado alone could receive $3.7 billion to improve its roads, $917 million for public transportation and more.
Keith Porter is an adjunct professor in the Department of Civil, Environmental, and Architectural Engineering at 精品SM在线影片. He led a 2019 report called 鈥�.鈥� In it, Porter and his colleagues argued spending money now could save the nation trillions of dollars in coming decades鈥撯�搕hrough reducing the costs for repairs, preventing deadly disasters such as bridge collapses, keeping commercial trucks on the move and more.
Porter sat down with 精品SM在线影片 Today to talk about the new infrastructure bill and why living with aging roads and bridges is like living with credit card debt.
A lot of critics of this bill have expressed sticker shock. But you鈥檝e made the case that it will cost us a lot more money in the long term not to invest in infrastructure.
Keith Porter
It鈥檚 a false economy to skimp on our utility and transportation infrastructure. We all rely on it. Society doesn鈥檛 work without roads, bridges and water systems.听
What will this bill mean for Colorado?
If Colorado is like the rest of the nation, this bill is going to partially close our investment gap in infrastructure, but it鈥檚 not going to close it completely. Nationwide, the $1.2 trillion investment is about half of what the (ASCE) says we need to spend over the next 10 years just to have adequate infrastructure. And the number keeps climbing because we under-invest.
So you see this as just a start?
It鈥檚 like paying only half your credit card bill. We can鈥檛 live off that credit indefinitely.
When you look at Colorado, what are some of the biggest challenges facing our infrastructure?
We鈥檝e got hail and tornados, and we鈥檝e got flooding, just like our neighboring states. We鈥檝e got fire in the wildland-urban interface. To some extent, we have earthquakes, less than California, but we also build weaker. We have all of the natural disasters that cost the country big bucks, except for coastal flooding and hurricanes, obviously.听
How much money do we stand to save by making our infrastructure more resilient to those kinds of hazards?
We estimate, for example, the money that gets spent on making our roads and bridges more resilient to flooding will save $8 for every dollar spent. You either pay for it now, or you pay for it a whole lot more later.
Flooding is clearly a big issue in Colorado鈥攕omething we learned in 2013 and again this summer when a mudslide shut down I-70 around Glenwood Canyon for weeks. Can investment in infrastructure prevent that kind of disaster in the future?
The climate is getting hotter, and we鈥檙e going to have more and more wildfires. They鈥檙e going to be followed by more severe rains, and we鈥檙e going to get mudslides. It鈥檚 going to be really hard to make that road mudslide-proof.
But most of our roads are the stuff you drive on to get to the 7-Eleven or your child's school. What you do is build the road higher and the storm sewer system better so听the water can run off into a storm sewer rather than sweeping you and your kid away.
This week鈥檚 wildfire near Estes Park also drove home just how vulnerable the state is to fire. What can we do to reduce those risks?
We have guidance called the International Wildland-Urban Interface Code. If we adopt that for areas where cities grow into wildlands, it could save $3 dollars for every dollar spent and maybe more.听
What kind of actions does that code recommend?
It says you can鈥檛 build the sidings of buildings out of vinyl鈥撯�搖se cement board or stucco, instead, something that can鈥檛 ignite. It requires you do things like put a noncombustible skirt around the house so there aren鈥檛 trees and bushes right up against it. Just having that gravel skirt makes a huge difference.听
Now that this bill has been signed, what do you think the biggest priorities are for improving infrastructure around the country? Roads? Bridges? Power grids?听
If you look at the from the ASCE, there are Cs and Ds across the board. We have to do it all. It鈥檚 too late to say, 鈥淵es this, but not that.鈥澨齌hat鈥檚 how we got here in the first place鈥撯�揵y economizing on things you just don鈥檛 economize on.
