CLEVELAND: A survey finds that Cleveland has more than 6,000 blighted homes that could cost $60 million to raze after years of extensive demolitions throughout the city.

Officials at the Thriving Communities Institute, an arm of the Western Reserve Land Conservancy, believe their findings support the need for continued, aggressive efforts to combat blight.

A top aide to Mayor Frank Jackson tells the Plain Dealer (http://bit.ly/1MusJFb ) that every section of the city is worth protecting.

Chief of staff Ken Silliman says Cleveland rejects arguments that itís better to encourage some homeowners in blighted areas to leave so that entire blocks can be demolished to make room for new development.

More than 11,000 vacant houses and crumbling commercial buildings in Cleveland have been torn down in the past nine years.
