HOUSTON — Cleanup is getting underway in Houston, where officials estimate at least 250,000 buildings have flood damage from Hurricane Harvey.

Piles of debris are showing up all over Houston as parts of the community are drying out from the devastating storm.

Items inside homes in many Houston neighborhoods are being taken out to the curb to be thrown away in buckets. 

Mayor Sylvester Turner walked through one of the neighborhoods Tuesday afternoon, meeting with a couple of the families on the street. Turner thinks at least one-third of families in the area are elderly, so they're trying to give them extra help. 

Crews are coming in to help them clean out homes of sheetrock, as well as mattresses, clothing or any kind of furniture, especially the carpet and carpet pads, before they start to create mold.

Turner said help arrived from San Antonio a couple of days ago. Help is also arriving from Austin, which will help create more than 250 different crews going around the city of Houston.

"We want to get to the point where we are expanding capacity, so that when you're driving through the city of Houston, you will see us out there picking up this debris,” Turner said.

Parts of the city are still under water, especially along the Buffalo Bayou. The area is still under a curfew right now, which is in effect from midnight to 5 a.m. It's also under a mandatory evacuation order.

Hundreds of families were forced out over the weekend because of persistent flooding due to the releases from the dam up the bayou.
