Documentation on the Leith Lindsay Flood Protection Scheme has been delivered to the Otago Regional Council by its consultants, but it is not yet known if it will allow the project to move forward.
The council has been seeking information, described as "critical" to the progress of scheme, from its consultant, Opus, for nearly six months.
Council environmental engineering and natural hazards director Gavin Palmer said Opus delivered design and contract documentation for the Union to Forth Sts reach of the Water of Leith, including scheme cost estimates, last week.
The council was reviewing it.
If the required information was included and up to standard, the council would look at developing the project, Mr Palmer said.
However, the delays meant no construction work would be undertaken this year despite hopes to have tenders out and work begun before Christmas.
"It has shunted the project out one year," he said.
