Any remaining Recovery Act money must be spent by September 2013.
Through the awarding of the stimulus money, Porter said, the Obama administration largely has shifted the way federal funds are dispensed.
She said the federal government often seeks to fund "the best demonstration project," which can be evaluated and possibly replicated, and encourages partnerships with nonprofits and other jurisdictions.
The competition, she said, is stiff.
"We are competing with L.A., New York, Chicago," Porter said. "I think the quality has really been pushed up in terms of innovation."
Continuing to win grant money is key to the city's finances.
In the 2011 fiscal year, the last year for which complete data are available, the city received $1.2 billion from federal and state grants.
Currently, each city department applies for its own grants, a process that can be confusing when more than one department applies for a grant.
"The federal government often comes back to us and says, 'Which one is your priority?' " Porter said. "What we're trying to do with this office is shift that so we're having that conversation internally."
Other jurisdictions - Porter cited Los Angeles and Massachusetts as models - are enacting similar plans, turning their recovery officers into grant gurus.
Porter said her first priority was likely to be seeking public safety funding. The new job will pay $115,000 per year.
