The San Diego Union-Tribune » San Diego is facing decreased funding for infrastructure combined with a longer list of needed projects, creating a $1.57 billion gap that is jeopardizing the city’s ability to fix sidewalks, build bike lanes and keep parks in good shape. The gap is $310 million larger than it was a year ago, despite increased focus on the problem by city officials and a 2016 ballot measure that created the first revenue stream devoted to infrastructure projects.
