Police calls for service at the properties stabilized in colder months, but have bumped up again with warmer weather, police spokesman Joel DeSpain said.

The primary issue for police centers on the lack of long-term or permanent property managers at each site, DeSpain said, adding that Heartland is working to resolve the situation. Problems, he said, are often related to people being allowed into the buildings when they shouldn’t be there. The hope is these situations, and calls for police service, will be mitigated with more consistent management, he said.

The city’s Affordable Housing Initiative, begun in the 2015 budget, relies heavily on federal Low Income Housing Tax Credits to help developers finance 60 percent to 70 percent or more of such projects. The initiative seeks to create 1,000 lower-cost units — including 250 units for the homeless — over five years.

City officials see the combination of city support and tax credits — secured through the Wisconsin Housing and Economic Development Authority — as the most potent way to create such housing in locations across the city near transportation, schools, groceries and other basic needs.
