What the Oroville Dam Disaster Says About America’s Aging Infrastructure
It’s time to invest in the future. · Fortune

This past week, heavy winter rain caused a 250-foot-long section of northern California's Oroville Dam's principal spillway to collapse. In response, state officials began releasing water from an adjacent emergency spillway, leading to the unexpected and rapid erosion of the ground below and the evacuation of 180,000 residents from their homes.

The crisis, which exposed glaring weaknesses with the dam complex, also carries an important lesson for the nation: Increasingly, extreme weather driven by climate change is placing substantial stress on America's aging infrastructure.

What's needed now is a massive investment in government infrastructure, bulking up agencies that maintain drinking and wastewater treatment and distribution systems, flood control, and transportation services. In the absence of additional spending, the combination of extreme weather events and population growth will lead to more system failures and congestion, as well as reduced prosperity for American workers and their families.

Unfortunately, President Donald Trump has put forward an infrastructure plan that will continue the nation's trend of underinvestment. In response to the situation at the Oroville Dam, White House Press Secretary Sean Spicer said, "The situation is a textbook example of why we need to pursue a major infrastructure package in Congress."

Yet instead of pushing for direct federal expenditures on infrastructure like dams, highways, and rail systems, the president has called for huge tax cuts for Wall Street equity investors. In exchange for investing in infrastructure projects, the Trump administration would like to offer investors a tax credit equivalent to 82 cents on the dollar.

While tax credits may boost Wall Street profits, they will do nothing for the country's estimated 2 million dams. Private equity capital can cost 3 to 5 times more than traditional municipal debt. Moreover, tax credits are not well suited to facilities that don’t generate a stream of user fee revenue. For this reason, dam repair and rehabilitation need direct funding from government.

By 2020, 65% of dams in the U.S. will be past their designated lifespan of 50 years; the Oroville Dam itself was built 49 years ago. As dams age, physical weaknesses, cracks, and leaks require more frequent and expensive repairs to keep them operational and safe. The American Society of Civil Engineers classifies nearly 4,000 dams as "deficient," meaning these facilities have aged to the point where they are more susceptible to failure.
