So many abandoned buildings exist in Flint that demolition is targeted first to those given “Emergency“ status, meaning properties in danger of imminent collapse or which were recently set on fire. Non-emergency teardowns, usually houses with collapsing foundations that can't be salvaged, are removed next. A house demolition typically takes one day, costs $6,000, and creates an average of 200 cubic yards of waste. With the exception of the basement foundation and slab—which are ground up for use in road construction—the house remains are taken to nearby landfill sites. In the morning, a house exists. By late afternoon, the hole where it once settled is replaced by backfill, topsoil, and grass seed.
