LOS EBANOS, Texas (AP) — The U.S. government has been trying to take Pamela Rivas’ land for a border wall since before Joe Biden was vice president.

From a brushy bluff, Rivas can look across the Rio Grande to Mexico on the other side. She spent her childhood fishing on the river. The government wants to bisect this property with steel fencing that would cut her off from the water, paying her just for the strip of land where it would build. In the meantime, the land is under constant surveillance from border agents who drive across it without her permission.

“We’ve been in court for 12 years now,” Rivas said. “It’s devastating. This is my inheritance from my family.”

Biden faces immediate pressure when he enters the White House in January to fulfill a pledge to stop border wall construction. But he also will confront tough choices left behind by President Donald Trump, whose administration has ramped up construction efforts across the Southwest in its final weeks, as well as skepticism about his own record on border walls.

As a senator, Biden voted for efforts to take private land under the Secure Fence Act of 2006. And while he was vice president to President Barack Obama, the government continued building and pursuing lawsuits against border landowners. About 650 miles of barriers were completed under that law through 2011.

In South Texas’ Rio Grande Valley, where Rivas and dozens of landowners are fighting construction, Obama built more barriers than Trump.

“We’re a little less naïve than last time,” said Ricky Garza, a lawyer with the nonprofit Texas Civil Rights Project, which represents Rivas and other landowners. “What we saw 10 years ago was a failure to prioritize the border as an important place where policy was happening.”

Biden will inherit a massive wall-building effort that accelerated in Trump’s final year. Work crews are blasting through mountains and destroying tree-like cactus and other habitat in Arizona and New Mexico. Almost all of the construction under Trump has taken place in wildlife refuges and Indigenous territory that already belongs to the U.S. government. While the work is considered “replacement” of older barriers, crews are removing small vehicle barriers and installing towering steel posts and lighting that are far more restrictive.

The Trump administration says it has completed 400 miles and pledged to reach 450 miles by the end of the year. And it has locked in contracts to build hundreds of miles more. More than two dozen projects are underway and contracts are signed with at least five construction companies, totaling $7 billion, according to government figures.
