Citing health and safety concerns, San Jose officials plan to remove residents of a popular homeless camp on Thursday. The 75-acre camp, known as "The Jungle," houses about 300 people and is considered the largest homeless camp in the United States. Residents live in tents, shacks and treehouses amid piles of trash. San Jose is spending $4 million to subsidize housing for those removed from the camp, but critics say the subsidies are inadequate to cover rising rents.
