Rebuilding of Yellowstone may take years, cost over $1B
Created in 1872, Yellowstone was the first of the national parks that came to be referred to as America’s best idea. Now, the home to gushing geysers, thundering waterfalls and some of the country’s most plentiful and diverse wildlife is facing its biggest challenge in decades.
Floodwaters last week wiped out numerous bridges, washed out miles of roads and closed the park as it approached peak tourist season during its 150th anniversary celebration. Nearby communities were swamped and hundreds of homes flooded as the Yellowstone River and its tributaries raged.
The scope of the damage is still being tallied by Yellowstone officials, but based on other national park disasters, it could take years and cost upwards of $1 billion to rebuild in an environmentally sensitive landscape where construction season only runs from the spring thaw until the first snowfall.
Based on what park officials have revealed and images and video from a helicopter, the greatest damage seemed to be to roads. Large sections of the road were undercut and washed away as the Gardner River jumped its banks. Perhaps hundreds of footbridges on trails may have been damaged or destroyed.
“This is not going to be an easy rebuild,” Superintendent Cam Sholly said. “I don’t think it’s going to be smart to invest potentially, you know, tens of millions of dollars, or however much it is, into repairing a road that may be subject to seeing a similar flooding event in the future.”
Reestablishing a human imprint in a national park is always a delicate operation, especially as a changing climate makes natural disasters more likely. Increasingly intense wildfires are occurring, including one last year that destroyed bridges, cabins and other infrastructure in Lassen Volcanic National Park in Northern California.
Flooding has done extensive damage in other parks and is a threat to virtually all the more-than 400 national parks, a report by The Rocky Mountain Climate Organization found in 2009.
Mount Rainier National Park in Washington state closed for six months after the worst flooding in its history in 2006. Damage to roads, trails, campgrounds and buildings was estimated at $36 million.
Yosemite Valley in California’s Yosemite National Park has flooded several times, but suffered its worst damage 25 years ago when heavy downpours on top of a large snowpack — a scenario similar to the Yellowstone flood — submerged campgrounds, flooded hotel rooms, washed out bridges and sections of road, and knocked out power and sewer lines. The park was closed for more than two months.
Congress allocated $178 million in emergency funds — a massive sum for park infrastructure at the time — and additional funding eventually surpassed $250 million, according to a 2013 report.
But the rebuilding effort once estimated to last four to five years dragged out for 15, due in part to environmental lawsuits over a protected river corridor and a long bureaucratic planning and review process.
It’s not clear if Yellowstone would face the same obstacles, though reconstructing the road that runs near Mammoth Hot Springs, where steaming water bubbles up over an otherworldly series of stone terraces, presents a challenge.
The Yosemite flood was seen by the park as an opportunity to rethink its planning and not necessarily rebuild in the same places, said Frank Dean, president and chief executive of the Yosemite Conservancy and a former park ranger.
The southern half of the park is expected to reopen this week, allowing visitors to flock to Old Faithful and other sites. The flood-damaged northern end may not reopen this year.
