The administration's plan, announced Tuesday, calls for higher fees per vehicle - which are good for a week - during peak periods at "highly visited" national parks.
The affected parks would include Olympic National Park and Mount Rainier National Park in Washington, as well as Yosemite, Yellowstone, Grand Teton, Glacier, Grand Canyon, Denali, Arches, Bryce Canyon, Canyonlands, Sequoia & Kings Canyon, Zion, Arcadia, Rocky Mountain, Shenandoah and Joshua Tree.
Per procedure, NPS has opened the proposal up to public comment for 30 days, set to expire 6 November.
The money is "badly needed", the agency says, and would be used for "improvements to the aging infrastructure of national parks".
The NPS is also proposing revised fees for commercial tours. The proposed hike would also affect 16 other popular parks around the country. If implemented, the cost of private vehicles would more than double to $70, while fees for a motorcycle would hit $50.
Flagstaff resident Brittany Montague said the proposed increase is "completely unreasonable", especially for young families and those making a day trip to national parks.
Tesla reportedly headed to China to build new factory
As such, establishing a factory in China will be a major deal for Tesla as it works to ramp up its production around the world. Tesla would still have to pay a 25 percent duty on cars built in a free trade zone, but it could lower its production costs.
Belcher said 80 percent of fees are retained by individual parks, with the remainder going into a national pool for distribution to parks across the country.
"Parks that have been enjoying increased visitation would then potentially see a significant drop-off in visitors, which would then result in a decrease in entrance fees and then, the whole thing might actually backfire", she said. And this isn't the first time that the Park Service has made drastic changes to entrance fees in the last few years.
Aging infrastructure including roads, bridges, campgrounds, waterlines, bathrooms and other visitor services are certainly in need of maintenance, especially when you consider that national parks are seeing more and more visitors each and every year - those increased visits takes a toll on everything in place.
The news of the possible increase did not sit will people who frequent the park.
"You don't need much money to go to the parks, just money for gas, but with this?" said George Holland, an Oakland attorney and president of the city's NAACP branch.
The new fee schedule would establish a $70-per-car peak season fee for the parks. The public can submit comments here. The cost of the annual pass that lets visitors into all national parks and federal lands would remain unchanged at $80.
"The enormity of the increases exceeds any increases in the history of the National Park Service", said Maureen Finnerty, Chair of the Coalition to Protect America's National Parks, an organization of current and former parks employees.
According to Rob Smith, Northwest Regional Director of National Parks Conservation Association: "For many people, this shuts off access at a time when we want to get people outdoors, and get people who haven't been coming to the parks to come".
