Prototypes of President Donald Trump’s proposed wall along the Mexico border will be built in Otay Mesa, according to a San Diego Union-Tribune report.

Twenty prototype bids were selected by the administration to be erected in the border community, the UT reported.

The prototypes will be constructed on a roughly quarter-mile strip of federally owned land within 120 feet of the border, according to the Associated Press.

The U.S. government anticipates spending $200,000 to $500,000 on each prototype, the AP report continued.

During the prototype construction period, which is forecast to begin in June, law enforcement is expecting protesters.

“As part of our community policing philosophy, we work closely with any party or group that wishes to express their views in a law abiding manner,” San Diego police spokesman Lt. Scott Wahl said in a statement to the UT.

It’s unclear whether local law enforcement will provide beefed up security at the construction site, and whether San Diego would be reimbursed by the federal government for any added patrol.

While Trump has continued to push for the wall’s construction, funding for the project has not been secured. The latest construction cost estimates are upward of $21 billion.

During his campaign for president, Trump insisted Mexico would pay for the wall, while Mexico’s president Enrique Peña Nieto has said his country has no intention of funding the construction.
