WASHINGTON — Two months after Detroit became the largest city ever to file for bankruptcy, top Obama administration officials will be there on Friday to propose nearly $300 million in combined federal and private aid toward a Motown comeback — only a fraction of the billions the city owes and a reflection of the budget and political limits on President Obama.

This first major infusion from the federal government, which administration officials say will not be the last, would be used to help clear and redevelop blighted properties, improve transportation systems, bolster the police — especially around schools — and overhaul city management systems wrecked by years of poor administration and inadequate resources.

The package follows weeks of meetings in Detroit and at the White House between the administration team and local business, labor and philanthropic leaders on how best to pool existing resources. Final details are to be worked out in a two-hour meeting of the federal and local officials at Wayne State University, participants said.

While Mr. Obama remains in Washington as fights over the budget and health care threaten a government shutdown at the start of a fiscal year on Tuesday, he is sending a delegation led by his chief White House economic adviser, Gene B. Sperling, which includes three cabinet members: Attorney General Eric H. Holder Jr.; Shaun Donovan, secretary of housing and urban development; and Anthony R. Foxx, secretary of transportation and a former mayor of Charlotte, N.C.
