A NEW plan for Nurragingy Reserve that includes an adventure course, boardwalk and function centres will take up to 30 years to realise and as yet has no estimated cost.
The Nurragingy Reserve Master Plan was released last month, about five months after the $3.5 million Chinese garden was completed in the park.
The plan has several maps that identify possibilities for commercial activity at three function centres, as well as refurbished gardens and playgrounds and upgraded pathways and roads around the 67-hectare reserve.
It also includes plans for an adventure course that could be used by groups such as schools and for personal training.
But none of this will happen overnight.
Blacktown mayor Len Robinson said the council needed to create the plan to meet the lease conditions with the Western Sydney Parklands Trust.
He said the proposal was "to revamp the existing facilities within the reserve" first over the next decade before starting on new infrastructure.
Councillor Robinson said the new infrastructure — including an extended boardwalk, wetlands, pavilion-style function centre and walking tracks — is in the 20- to 30-year plan.
The council has not released any costings for it yet.
Cr Robinson said details on cost would be looked at after the public display period.
In the long run, he was confident the redevelopment would strike a balance between built and natural environments.
"Through these works the council will maintain the natural areas of the reserve, balancing the demands for leisure and recreation with that of ensuring the natural areas are cared for and maintained," he said.
Cr Robinson said the new function centres would open up a range of commercial opportunities, including festivals in the park.
Public display of the Nurragingy Reserve Master Plan closed on Friday. Council officers are expected to report back on submissions in the second quarter of the year.
