Almost five years after major flooding in the Wallsend commercial centre, Newcastle Council is calling for tenders to undertake detailed flood modelling work.
The town's main street was devastated in the June 2007 floods with 30 businesses damaged.
Eight of those have since left the area.
The modelling will look at the potential impact that floodwater would have on buildings and other structures, and whether they could fail during a major flood event.
Council's project manager Clare McLay says the work will also identify ways of alleviating the impact of flooding.
"So constructing new infrastructure, acquiring and demolishing properties that maybe identified in the high risk areas," she said.
"As well as widening bridges and enlarging stormwater channels."
