Two months before its new, year-round homeless shelter is set to open, Arlington County released encouraging results from the annual count of its homeless population.

During her monthly report to the Arlington County Board yesterday, County Manager Barbara Donnellan said the results form the count show an 18 percent decline in its overall homeless population from 2014, and a 34 percent drop in homeless families.

The count was conducted overnight from Jan. 28 to 29, and conducted in tandem with other jurisdictions around the region. While it’s not a perfect metric, Arlington Street People’s Assistance Network Executive Director Kathy Sibert said, the numbers are still worth celebrating.

In 2013, the count tallied 479 total homeless people in Arlington. In 2015, there were 239.

Many of those counted were staying in shelters or other temporary housing. The most dramatic number is 39, the number of unsheltered individuals counted in January. In 2013, that number was 146, good for a 73 percent decline. Sibert said those numbers can be directly attributed to the successful “100 Homes Campaign” in the county last year.

“The big thing is it’s such a cost-savings to all of the citizens,” Sibert said. “A study in the Journal of the American Medical Association estimates it costs communities up to $45,000 to provide care to someone on the streets, compared to only $22,000 when they’re housed.

Donnellan also revealed Tuesday that the county’s year-round Homeless Services Center will open in June, construction permitting. It had originally been slated for opening last fall. When it opens, the shelter will provide 50 permanent beds, 25 beds in the winter, five medical beds for homeless people released from the hospital, as well as a full kitchen and classrooms for job training.

“We focused on getting those medically vulnerable people on the streets into housing,” Sibert said. “That’s how you end homelessness. To end homelessness, you’ve got to get them into housing, so that’s what we’ve done.”
