"Our multi-pronged strategy to ensure the safety and security of the American people includes barriers, infrastructure, technology, and people".
"We are committed to securing our border and that includes constructing border walls".
The designs are between 18 and 30 feet, and will be evaluated on how well they deter climbers, how well they withstand breach attempts and what sort of awareness they allow agents who patrol the border.
Preparations for the prototype construction, which had been carried out for weeks, became more evident when the San Diego County Sheriff last weekend placed no-parking signs across roads and streets in business parks that populate the border area, according to Los Angeles Times. U.S. Customs and Border Protection announced that the companies would have about 30 days to complete construction on their prototypes in San Diego. Four of them will be built of concrete, and the rest from alternative materials.
"If you're in favor of the wall, you're entitled to speak in favor of it but peacefully, and that's what we're asking for".
In a video taken by the NBC 7 News helicopter, a photographer captured images of dirt being graded by tractors, and rectangular cutouts, presumably where the prototypes will be built.
Construction of eight models in a remote area of San Diego is about three months behind schedule, held up by losing bidders whose protests were eventually denied.
Six companies were selected to build the concrete and the alternative prototypes. "It may be a combination of designs being implemented", Villarreal told reporters next to existing border fencing.
Mr. Trump during the campaign said he wanted to see a border-long wall, but more recently has said between 700 and 900 miles need a barrier.
A complaint filed last week by California Attorney General Xavier Becerra, a Democrat, largely mirrors two others by environmental advocacy groups that allege the administration overstepped its authority to speed up construction of the wall. "The Department of Homeland Security would waive 37 federal statutes, as well as regulations that are related to those statutes, and he would also violate numerous state and local laws here in our great state of California".
Estimates for the cost of the border wall have ranged up to $38 billion.
