MP Bill Esterson, Sudell Ward Labour Councillor Patrick McKinley and Labour councillors on Maghull Town Council are urging everyone in Maghull to inspect plans which will see hundreds of new homes built at Parkbourn near to the Ashworth site.
The site, off Park Lane, has been earmarked for up to 300 new homes.
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.
Bill Esterson said: "This is a large scale development which will have an impact on the immediate community.
"We need to ensure that the neighbours are happy with the plans and the infrastructure is in place to cope with a development of this size. This includes shops and other community facilities.
"I urge everyone to fully inspect the plans and have their say."
Sudell Ward 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.
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.”
Maghull Town Council leader, Labour’s Cllr Maurice Byrne, said the Town Council and the Labour Action Team would be meeting residents about their concerns.
Cllr Byrne said: “This is a big development and we need to ensure the people of this community are given the chance to have their say on how this area evolves.
“We have made an informal visit to the site and already spoken to a number of residents, but we will be having further meetings in coming weeks to hear what local people think of the proposed scheme.”
