Congressional Democrats, including three from Nevada, have come out against a plan to more than double the entrance fees at some of the nation’s busiest and most iconic national parks.

In a letter sent Wednesday to Interior Secretary Ryan Zinke, 90 House members called on the Trump administration to work with Congress to fully fund the National Park Service rather than jack up fees at select parks.

The letter comes in response to a park service plan, unveiled last week, to boost revenue next year with peak-season pricing at 17 parks. During the busiest five months at those parks, entrance fees would more than double to $70 per vehicle, $50 per motorcycle and $30 per person.

The House Democrats called the proposal “misguided,” saying it would hurt local economies near the parks and prevent low-income families from seeing some of the nation’s most treasured places.

“Public lands belong to all Americans, not just wealthy families who can absorb the steep fee increases,” the letter says.

Reps. Ruben Kihuen, Jacky Rosen and Dina Titus, all D-Nev., signed onto the message to Zinke.

No Republicans signed the letter.

Park service officials have said the additional funds would be used to “improve facilities, infrastructure and visitor services, with an emphasis on deferred maintenance projects.”

If it is finalized, the peak-season increase is expected to boost entrance fee revenues by about 34 percent, from just under $200 million in fiscal year 2016 to more than $268 million.

The park service is also proposing entrance and permit fee increases for commercial tour operators.

The 17 parks were chosen because they are the top revenue earners for the service, accounting for 70 percent of all entrance fees collected nationwide.

The list includes several within a day’s drive of Las Vegas: Grand Canyon in Arizona; Joshua Tree, Sequoia-Kings Canyon and Yosemite in California; and Arches, Bryce Canyon, Canyonlands and Zion in Utah.

No park service sites in Nevada would be affected. The price of annual passes and lifetime passes for seniors would remain at $80.

The park service will accept public input on the plan through Nov. 23.

Peak pricing at parks

Starting next year, the National Park Service plans raise the entrance fee to $70 per vehicle, $50 per motorcycle and $30 per person during the busiest five months of the year at 17 national parks.

The peak season will differ depending on the park.

The higher fees would be collected from May 1 through Sept. 30 at Grand Canyon in Arizona; Sequoia-Kings Canyon and Yosemite in California; Arches, Bryce Canyon, Canyonlands and Zion in Utah; Denali in Alaska; Glacier in Montana; Grand Teton in Wyoming; Olympic in Washington; and Yellowstone in Wyoming, Idaho and Montana.

The peak season would run from Jan. 1 through May 31 at Joshua Tree National Park and from June 1 through Oct. 31 at Acadia in Maine, Mount Rainier in Washington, Rocky Mountain in Colorado and Shenandoah in Virginia.
