While Trump has insisted that the barriers be painted, the cost of painting them will reduce the length of the fence the government will be able to build. According to the internal analysis, painting or coating 175 miles of barriers “will add between $70 million and $133 million in cost,” trimming the amount of fencing the Army Corps will be able to install by four to seven miles.
