Deputy mayor Chris Staynes, chairman of the council's economic development committee, said that ranged from new cycleway trail connections to Farra Engineering's idea of a new engineering hub for the city.
The waterfront development project remained a "very high priority" for the city, and the council was working on a business case to support an application for more than $50 million, he said.
However, city councillors had also been encouraged to nominate potential projects to be added to the list, and Dunedin's MPs had been asked for input on projects that were "good prospects", he said.
The council's aim was to identify priority projects and work to progress them directly, or support outside organisations, companies or individuals that were, he said.
"At this stage it's hard to qualify any of them in terms of dollars, because the work's being done to work that up, but we've probably got applications that are going to vary from above $50 million down to maybe $10 million or so."
If the city was successful in securing funding for a cluster or projects, results could be "very, very good" for the city, he said.
"All of them have got to justify themselves on the basis of economic benefit. If we're lucky enough to get a handful, or a dozen, across the line between the councils and the city itself ... then I think it's really, really good."
Enterprise Dunedin director John Christie said Dunedin and the surrounding region offered "myriad" potential projects, but the effort to secure funds needed to be prioritised.
"We've only got so much resource, and each one of those will take a business case to be written.
"The harbour one is front and centre in terms of that piece, but there are a couple of others that we're anticipating we will be involved in as well."
He did not expect all projects to proceed to an application stage, and some would be led by private sector interests with no input from the council, he said.
But all of those on the list were capable of delivering new jobs or wider economic benefits to the city and the wider region, he believed.
"We'll be fully supportive of those sorts of initiatives even if we're not driving them, because they will ultimately lead to improved economic outcomes."
