The city of San Diego is suing the federal government for building razor wire fencing on city land near the Mexican border, arguing that the fence damages sensitive habitat and trespasses on city property. It argues that U.S. Marines illegally entered city land in December and built fences in Marron Valley, east of Otay Mountain. “The City of San Diego will not allow federal agencies to disregard the law and damage city property,” City Attorney Heather Ferbert said in a statement. It’s also part of a habitat plan between the city, California Department of Fish and Wildlife and U.S. The complaint says the federal agencies built the fence without city approval or notice.
