Maghull Labour Action Team is holding a public meeting to discuss the plans which will see hundreds of new homes built at Parkbourn near to the Ashworth site.
The meeting which is open to all interested members of the public, will be held at Northway School on July 13 between 6pm-7pm.
If given the go-ahead, upto 300 new homes could be built on the site off Park Lane.
Sefton Central Labour MP Bill Esterson and Maghull Labour Action Team, including Sudell Ward Labour Councillor Patrick McKinley and Maghull Town Councillors have visited the site and inspected the plans.
All want to ensure that Maghull residents, particularly those neighbouring the site, have a say on any future plans for their community.
Sudell Ward Labour Councillor Patrick McKinley said he wanted to ensure that any large scale housing developments were fully served for shops, community centre, other facilities and public transport - included North Maghull's long-awaited train station..
Cllr McKinley said: "If 300 houses are given the green light on this site, then we need to ensure that there are shops and facilities available.
"And that includes local transport which means we can put the case for the long awaited Maghull North Train Station.
"But first we need to fully inspect the plans and the long term impact of the development on the local community.
"That's why the Labour Action Team, Bill Esterson, Maghull Town Council and myself, are urging everyone to have a look at the plans and make their opinions heard by coming along to the meeting on July 13.
"We will take all of the comments and feedback from the meeting back to the planning department so they can each be addressed individually."
Sefton Central Labour MP Bill Esterson said he was planning to attend the meeting to hear the concerns for himself.
Bill said: "This is a large scale development which will have an impact on the immediate and surrounding Maghull community.
"We need to ensure that any development of this size takes into account its impact on the area, the infrastructure and the facilities.
"I'm sure we'll get a good turnout at the event and work together for the interests of Maghull."
The public meeting will be held at Northway School on July 13 between 6pm-7pm.
