In June 2015, Walker brought the foundation's annual board meeting to Detroit, the first since 1948, following the Ford Foundation's unprecedented $125 million contribution to the "grand bargain" deal that settled Detroit's historic bankruptcy and shielded the city's art collection from creditors.

The Ford Foundation's Detroit program officer will be charged with overseeing the $15 million in grants the foundation is making in Detroit annually, the most of any U.S. city, Walker said.

That total is in addition to its $8.5 million yearly payment to the bankruptcy "grand bargain" fund used to boost Detroit's municipal pension funds and shield assets of the Detroit Institute of Arts from ever being sold.

Walker said the new Detroit program officer will have an office inside shared space with another foundation. The Ford Foundation was planning to announce the hire internally on Tuesday before making a public announcement.

Robert Collier, president and CEO of the Council of Michigan Foundations, said he and others in the state's philanthropic foundation circles have been encouraging Walker to re-establish a physical presence in the city since the "momentous" 2015 board meeting.

"Having someone who is here is certainly strategically very important as opposed to having someone drop in once a month for a couple of days or having an endless stream of consultants," Collier said.

The stationing of a new Ford Foundation staffer in Detroit comes as the foundation is looking to wade into investing in affordable housing in the city's neighborhoods outside of downtown and Midtown.

In April, Ford Foundation's board announced it would take $1 billion out of its $12.5 billion endowment and put it into mission-related investments focused on tackling poverty abroad and affordable housing in the U.S.

Walker told Crain's that Detroit and surrounding suburbs will be a "primary focus" for the foundation's housing development investments.

"What drove it was the realization was that we're going to have to leverage every asset we have to advance revitalization in Detroit," Walker said. "And those tools must go beyond our grant-making."

The Ford Foundation has not set a target dollar amount for affordable-housing investments in Detroit.

But they're open to hearing financing proposals from developers with projects outside of the 7.2-square-miles of greater downtown, Walker said.

"Rather than setting an artificial target, we want to generate as much demand as we can," Walker told Crain's.

The Ford Foundation is using its endowment for targeted investments in housing that it expects will be paid back over time and is in addition to the 5.5 percent of charitable grants it gives away annually.

Collier said the Ford Foundation's new Detroit program officer will be critical to carrying out its neighborhood redevelopment mission.

"Community building is very much relationship-based and very much face to face," he said.

Walker said the foundation is looking to invest in a range of housing projects for households earning between 75 percent and 150 percent of the median household income. In Detroit, that would benefit lower-income families earning between $19,300 and $38,600 annually.

The Ford Foundation plans to hire a director of its $1 billion mission-related investments this summer, Walker said.

"We expect to start making investments in the fall," Walker said.
