The plans will be discussed at a public meeting at Castlecliff School on May 26.
"Anything can change at the moment," Mr Waugh said.
"At the moment we've done the best that we can with what the community's given us but it's community driven."
Mr Waugh said the work on the top three blocks of Rangiora St could be done within current budgets in the next 18 months.
He said the plans would help the council to carry out the work based on what the community wanted.
"They've got the skills in-house in terms of turning that into reality."
Mr Waugh said that at the May 26 meeting the public will also be updated on the overall plan for Castlecliff and progress on the cycleway and the port and boat ramp upgrades.
