Arlington is seeking volunteers to scour the streets next month and find the county’s most vulnerable homeless citizens.

The effort is part of the county’s 100 Homes Campaign, which will try to cut “chronic homelessness” in Arlington in half by July 2013. The campaign will place some of Arlington’s most medically-vulnerable homeless individuals — described as “those most likely to die if not housed quickly” — in permanent supportive housing.

The county is looking for volunteer surveyors, data entry personnel and headquarters staff to work from Oct. 17-19. Surveyors will be asked to go out in teams and interview homeless individuals from 3:30 to 7:30 a.m., while data entry will be done between 6:30 and 9:00 a.m. More information on volunteering can be found on the 100 Homes Arlington web site.

“We have made great strides in addressing homelessness in Arlington, but our work is far from complete,” County Board Chairman Chris Zimmerman said in a statement. “The 100 Homes Campaign brings important focus to helping some of the most vulnerable members of our community – those living on the streets.”

Arlington’s campaign, co-chaired by County Board member and state Senate candidate Barbara Favola and Shooshan Company president John Shooshan, is based on the national 100,000 Homes campaign.
