In a market where rental housing is tight and affordable housing even more scarce, there’s good news for some families scrambling to make ends meet. It comes in the form of a project called Sienna Green Phase II in Roseville: 50 affordable, two and three-bedroom apartments for families in a building so new that workers were hard at it around the grounds early this week, finishing off porches on the structure’s front façade, painting, watering new day lilies. Aeon is one of many organizations around the state dedicated to expanding the affordable housing market following one of the worst economic recessions in our history. Some 125,000 Minnesotans are “one paycheck away” from losing their housing, says Ciganik, who is vice president of housing development for Aeon, the nonprofit that spearheaded this building project. Sienna Green has only six or seven family apartments unrented, she says.
