The city of Detroit on Monday evening proposed new details, including potentially larger cuts to pensions for some retirees, for its plan for paying off portions of its debts and emerging this year from the nation’s largest municipal bankruptcy.

The revised document clarifies how Detroit wants to pay off only parts of what it owes to banks, city employees and other creditors and wants to spend about $1.5 billion on remaking its poor municipal services. An earlier version of the document was made public in February, and a federal bankruptcy judge must decide as early as this summer whether to approve the plan.

Many of the city’s creditors have objected vehemently to Detroit’s original proposal, known as a plan of adjustment, as well as an accompanying disclosure statement, and the rewritten documents seem unlikely to draw new support, at least in some quarters.

The recast plan lays out an $85 million termination agreement with financial institutions over a so-called swaps deal the city made in 2005. It also describes a deal, highly unusual in a municipal bankruptcy, to spare the city’s prized art collection from sale and avoid deeper cuts to pensions with funds from foundations and the state, still not yet secured from the State Legislature.
