sentences:  In 2010, Detroit mayor David Bing introduced a plan to demolish approximately 10,000 of an estimated 33,000 vacant homes in the city because they were "vacant, open, and dangerous".The decision was driven by the reality that for financial constraints, the city's existing resources simply could not maintain providing services to all areas.However, the decision also reflected a desire to "right-size" Detroit by relocating residents from dilapidated neighborhoods to "healthy" ones.
