A PETITION to save Pioneer Park has been lodged with Coffs Harbour Council as supporters vow their fight to save the site is far from over.

In all, 550 people signed the campaign for council to scrap the Duke St extension.

Local resident Cheryl Cooper said councillors needed to reconsider the plans.

"We're waiting to see if the council is prepared to put it back to a council meeting (for reconsideration)," she said.

"If they still say they're going ahead with it then it's stand-in-front-of- the-bulldozer time.

"People say 'it's just a little park' but those mature trees are really important to koalas, and to us."

The council states the permanent road will alleviate traffic from planned work at the Harbour Dr / Gordon St intersection.

But Cr Sally Townley said it was based on flawed plans.

"The premise is that it will help avoid the lights but the council's own study states in five years the traffic lights won't work very well, and in ten years it won't work at all because queues will clog up surrounding intersections," she said.

Supporters rejected Mayor Denise Knight's comments that the park was not being used by the community.

Coffs Harbour Neighbourhood Centre volunteer Kathryn Auger said it was an important space for youth and people with a disability.

"The park runs from the village that has disability support services and has access for people in wheelchairs or scooters into town safely. It doesn't make sense for a road to go through it," she said.

Cr Knight this week requested the council supply a detailed briefing of the planned work before the matter is re-tabled to councillors.
