DANBURY - The final details of a plan to end homelessness in the city within 10 years will be hammered out over the next few weeks. Once completed, the draft will be given to the Danbury Common Council , which could consider the issue in November, said Probate Court Judge Diane Yamin , who chairs a task force on the issue. The price tag hasn't yet been figured, but among the costly ideas is that Danbury will need 436 new affordable housing units over the next decade. They could be built through a combination of private, city, state and federal efforts. Other goals include: Creating an agency or authority that identifies the homeless and guides them toward help. Maintaining existing homes so the occupants of existing low-cost housing don't become homeless. Helping people with back rent, security deposits, rental and mortgage assistance. No figures are yet available for these costs. "It's a lot of work, but a figure is needed," said Carolyn Sistrunk , executive director of the Danbury Housing Authority . The city counted 321 homeless in a one-day survey in 2005, and the report recommends the city develop 15 units of affordable, permanent housing in the first year. That would increase to 20 in the second year. For the third through 10th year, the target would be 30 units of affordable housing per year. Various state and federal agencies describe affordable housing in different ways, and one section of the final report will define the terms for the local housing. A question the committee settled Friday was whether the group's plan would cover only Danbury or the region as a whole. "If we're looking for an agreement with other towns, we have to make sure other towns buy into the plan," Sistrunk said. After discussion, members of the group agreed the plan is Danbury's plan, and they expressed hope that other towns would also consider the issue. "I think the best we can hope for is we can encourage other communities to see this as a regional issue," said Joan Carty , director of the Housing Development Fund , which supports the building of affordable housing in Fairfield County. "Danbury can't be expected to do all of it." Planning Director Dennis Elpern said building new housing is extremely expensive, and rather than building new homes to create affordable housing, new affordable housing is more likely to come from people converting existing homes into that use. Elpern said the city's zoning rules do not prohibit or exclude affordable housing now. In fact, Danbury's guidelines give bonuses to developers who include affordable housing in their plans. "The regulations do not require developers to include affordable housing in Danbury," Elpern said. "That would be new in town."
