A sinkhole the size of a city block in a residential area of northeast Baltimore opened up Wednesday, sucking in 10 cars and forcing evacuations of homes nearby. No injuries were reported from the sinkhole.

The cars that fell into the sinkhole that opened in the first block of 26th Street were all empty.

Baltimore Mayor Stephanie Rawlings-Blake said that the city has been through sinkholes before and has a designated team to respond.

Residents near the sinkhole had complained about the street where the sinkhole occurred. One woman saw cracks in the road and noticed they were getting bigger. She knew a sinkhole could occur, and all the city did was place blacktop to patch the cracks.

Another resident Jim Zitzer saw a block-long crack and stopped parking on that side of the street because he predicted a sinkhole would eventually occur.

Rawlings-Blake said a sidewalk and retaining wall slid with mud and debris onto railroad tracks used by CSX.

Authorities will now have to examine the strength of the road and buildings near the sinkhole to ensure they are structurally sound.

The sinkhole can be blamed on rain that has drenched the area recently. The National Weather Service said more than 3 inches have hit the area since Tuesday.

An official Twitter account of the city of Baltimore issued this message Wednesday afternoon: "Please avoid the area of 26th St & N Charles St. A major sinkhole has opened impacting the CSX rail below.. Multiple city agencies on scene."

Railroad traffic has been suspended in the area as well.

Nels Schumacher had his vehicle sucked into the sinkhole and saw it all happen when neighbors urged him to go outside.

"I was standing here taking pictures of my car as it was slowly moving toward the ravine," Schumacher told the Baltimore Business Journal. "The cars sank about 5 or 6 feet, and then the whole wall came down."
