Houston — While the number of evacuees seeking refuge in Houston's emergency shelters dwindled 10 days after Harvey struck, many people who had left by Monday still faced dire housing needs.Some returned to public housing complexes inundated with sewage and mud. More than 50 000 went to government-paid hotels, some far away from homes and schools. Others moved in with family and friends.Harvey did not discriminate, inundating exclusive neighbourhoods and low-lying apartments for the poor, and was blamed for at least 60 deaths. Most of the evacuees at the George R Brown Convention Centre were lower-income, but some were from wealthier areas.Now, about 1 500 remain at the convention centre, and several said they were homeless, disabled or from public housing. About 2 800 were at the NRG Centre, another convention centre that opened after George R Brown reached double its original capacity.Harvey struck Texas on August 25 as a Category 4 hurricane, but brought the worst flooding to Houston and other areas as a tropical storm. The rain totalled nearly 1.3m in some spots.Mayor Sylvester Turner has declared Houston "open for business", and offices and restaurants across downtown are expected to reopen on Tuesday after the Labour Day holiday.Concerns about further explosions at a damaged chemical plant eased after officials on Sunday carried out a controlled burn of highly unstable compounds at the Arkema plant in Crosby. Three trailers had previously caught fire after Harvey's floodwaters knocked out generators.Housing programmeAuthorities said it was safe for residents of a 2.4km evacuation zone around the Arkema plant to return. They were forced to leave August 29.The Federal Emergency Management Agency said 53 630 residents displaced by Harvey are currently staying in government-funded hotel rooms.FEMA says it has about 560 000 families registered for its housing assistance programme.The temporary housing has been provided for 18 732 households, said FEMA spokesperson Bob Howard. Once people are granted the assistance, there is a minimum allotment of 14 days, but that can be extended on a case-by-case basis.FEMA officials also are weighing other options such as mobile homes should the need arise.After Hurricane Katrina struck New Orleans in 2005, FEMA bought thousands of mobile homes for people left homeless, but the programme was plagued by problems. Some victims who lived in the homes were exposed to high levels of formaldehyde, which was used in building materials.On Monday night, Texas Gov Greg Abbott announced that FEMA had granted his request for Community Disaster Loan assistance for areas hard-hit by the storm. Cities can obtain loans to help keep their operating budgets intact.While there were signs of hope for some displaced by Harvey, others were not so lucky. Nowhere else to goSome residents of the Clayton Homes returned to apartments filled with water and floors caked in mud and sewage.Clayton Homes residents were among the first to arrive at the convention centre last weekend, many riding in the back of city dump trucks. The complex is bounded on one side by an interstate highway and on another by Buffalo Bayou, the muddy waterway that jumped its banks and sent water rushing into people's homes.Piles of garbage and soggy furniture sat next to the gnarled remains of a fence separating the bayou from the complex. The rotting stench was present in parts of the complex."We didn't have anywhere to go but back here," said Laquinna Russell as she stood in the complex's laundry room with her husband, Antonio Washington, and one of their three children.Russell and Washington spent one night in a hotel room instead of going to the convention centre, but they came back after they ran out of money.Russell used bleach to scrub the bottom floor of their two-story home as well as she could, but fears about mold and bacteria have forced the whole family to sleep on the second floor.The children's newly purchased school clothes, however, were ruined. So was the family's TV, their couch and many of their belongings, including their two cars.They registered for assistance from FEMA, but Russell and several other people said they couldn't find a hotel nearby. And they're still responsible for paying their rent.Looters spottedRosie Carmouche spent two days at George R Brown with her two children, walking almost a mile to the convention centre as floodwaters slowly pushed toward her home. She showed photos of high water over parked cars on her street.The reason she came back home was what she saw on her way out of the complex."You had looters swimming back, breaking into these people's houses," she said.She didn't want to stay at the convention centre for too long, fearing for her possessions."They made you feel as comfortable as they possibly can. I will give them that," Carmouche said of the convention centre. "But when your mind is — you know what kind of community you live in? It's hard."D'Ona Spears and Brandon Polson managed to get a FEMA-funded hotel room near downtown but got kicked out after one night for lack of state identification. All of her paperwork had been lost in the floodwaters, Spears said.The family went to the Toyota Centre, the basketball arena near the convention centre that's also housing evacuees.'Nothing I can do'Then they were taken to a motel in Humble, a small city near Houston's international airport about 32km away.Spears said they have no transportation and no way of getting the children to school when it resumes next week."You can't just pick the hotel," she said. "You have to go further out, further out, further out."Morris Mack sat outside the main entrance to the convention centre, sharing a cigarette with another person as a military band played in the background.Mack arrived there August 30 and hadn't been able to re-enter his home in a public housing development in northwest Houston.While he registered for FEMA assistance, Mack's cellphone was wrecked by floodwaters, and he didn't have a working email address, making it difficult for the agency to get in touch with him or send him a check for assistance. He was waiting for government offices to reopen on Tuesday so he can get a government assistance card that he could then use to get a cellphone to communicate with FEMA."I've gotten to a point where it is what it is. There's nothing I can do about it. Just trust in God."
