An industrial estate at Greystanes that would support 2,000 workers and 800 construction jobs has been approved, and comment is being sought on a proposed industrial precinct at Marsden Park that could support another 10,000 jobs.

NSW planning minister, Kristina Keneally, said that both projects are in line with the plans to create jobs closer to where people live in Western Sydney.

"Planning approval has been given for an industrial park at Greystanes, which has potential to create up to 800 construction jobs and accommodate 2,000 workers," Ms Keneally said.

Preliminary construction could get underway in early 2010 at the $150 million DEXUS Estate Industrial Park.

The estate will include about 220,000 sqm of warehouse space and 21,000 sqm of office space, turning the former quarry into a modern complex.

Plans include a dedicated bus Transitway running along Reconciliation Drive to the employment precinct, meaning workers will be able to leave their cars at home.

Following public comment, a number of conditions were imposed upon the approval to ensure visual impact and traffic management issues are dealt with appropriately.

"Views from the surrounding ridgeline will not be obstructed and a revised internal road layout has also opened up two significant view corridors within the site," Keneally said.

Keneally also called for public comment on draft plans for a new employment hub at Marsden Park that could support 10,000 jobs.

Draft plans for Marsden Park Industrial Precinct include 205 hectares of land for warehousing and distribution, a 67 hectare business park and 36 hectares for bulky goods retailing.

"While predominantly an employment zone, the draft plans would also allow for 1,121 new residential dwellings to house 3,200 people close to the planned Marsden Park town centre to the north,” she said.

The plans also feature 92 hectares of conservation land and open space. Exhibition documents are available at www.growthcentres.nsw.gov.au
