A strategy proposal for a Carlingford reserve to become the site of a 218-space car park has angered the community.
About 250 residents at a public meeting objected to a strategy that could potentially place a commuter car park on Rainbow Farm Reserve.
The Hills Shire Council revealed its shire-wide car-parking strategy last month, identifying commuter parking sites along the existing bus network and the M2.
The proposed Coral Tree Drive car park is about 150 metres from the M2 and is surrounded by residential streets.
Carlingford resident Murray Bensley said the Coral Tree Drive site was impractical and would destroy a popular community reserve.
He suggested converting the park opposite Carmen Drive shops into a multi-storey car park and converting the two commercial properties opposite into a reserve.
"I think this has been poorly thought out," Mr Bensley said. "They should scrap all three proposed sites [in Carlingford] and look at other alternatives."
Hills mayor Larry Bolitho said now was the time for public debate.
"Going to community [for input on the strategy] would have been a much better idea," Cr Bolitho said.
"You can't go into their backyard and give them a half-baked idea and expect them to just cop it.
"These people want to contribute to what their community is going to look like." .
Cr Andrew Jefferies said the strategy had considered several options of where to place the 280 cars of commuters that at present park in residential streets.
"The strategy is about trying to provide an overall solution by identifying options for one of the most significant issues in the shire," Cr Jefferies said.
He said that what was needed now was feedback on what were possible options of suitable sites for the future.
