Cr Noel Whittle took a walk along the Stephen Street footpath the day it opened and was not impressed with its design.

Cr Whittle said council was presented a concept plan but he felt he was not able to voice his opinion as the plans were not set in stone.

The Stephen Street precinct underwent a $400,000 upgrade last month and was open to the public two weeks ago.

Cr Whittle said he believed the design of the footpath centred on appearance over functionality, as the angular curbing protruded into the walkway and the storm water retention technology would pose a risk to pedestrians.

"The overall usable width of the path has been reduced from the average two and a half metres down to just over one metre," Cr Whittle said.

Cr Whittle said there were three points in the footpath which were lowered to assist water catchment around trees, creating a hole in the surface.

A walkability and wayfinding audit was recently conducted by the South West Development Commission to transform Bunbury into a more pedestrian friendly city.

The assessment aimed to identify key areas of improvement such as speed limits, road crossings and footpaths and the need for new directional signs.

South West Development Commission regional coordinator Alan Cross said a more detailed study of the city centre would be carried out later in the year.

"Many people have made a range of suggestions that we are keen to explore to ensure the best possible outcomes for this project," Mr Cross said.

Stephen Street was still under construction when the assessment was carried out and Cr Whittle said he hoped the street would come under scrutiny when the more detailed audit was carried out.
