During his campaign for office, President Donald Trump told voters that if elected he would build a “big, fat, beautiful wall” from coast to coast. Along the 1,250 miles of Texas-Mexico border, 110 miles of fencing already exist. If the Trump administration decides to construct more fencing along the rest of the Texas border, it will have to navigate deep canyons, a national park, an ever-shifting river and a treaty with Mexico that requires binational consent before structures can be built in the river’s floodplains. In some parts of the border, the wall has aggravated flooding and resulted in diminished property values for landowners.
