Dundee will host an open-top bus parade if Dundee United win the Scottish Cup on Saturday.
The city council has already put down £3,100 in deposits for stewarding along the route to the city square the day after the final.
However, club officials stressed that the "contingency plans" were "taking nothing for granted" about the result.
Dundee United will face Tayside rivals St Johnstone in the final at Celtic Park in Glasgow.
Perth and Kinross Council is also considering plans for celebrations if St Johnstone lift the trophy, which will be announced in due course.
The £20,000 total cost of the Dundee event would be drawn from the city's Common Good Fund.
It would include an open-top bus parade and a presentation at the City Chambers before the team would show off the trophy from the balcony over City Square.
'Nothing for granted'
A similar event in the city square honouring Dundee FC's Championship victory was held on Sunday, and thousands of United fans turned out when the club won the Scottish Cup in 2010.
The decision to approve the initial expenditure for deposits was taken by chief executive David Dorward and a representative from each of the authority's political groupings because the council's policy and resources committee is not due to meet until after the final.
Dundee United director Derek Robertson said: "We'd all like to stress that these are contingency arrangements only and that we're taking nothing for granted nor making any assumptions about the result.
"Obviously, however, we're all hoping that the cup will come back to Dundee and, in view of the amount of planning and external bodies involved, it is necessary to have these contingency plans in place well ahead of the time.
"I'm sure similar plans are also in place in Perth."
