Hundreds of new retirement houses are to be built in Jersey's countryside, under plans drawn up by the States to rezone land.
The Housing Department has identified a significant shortage of them.
There are plans to build 215 dwellings for rent and 200 to buy, as well as 45 first-time buyer homes.
Parish constables have been asked to suggest sites for development, although 10 have already been identified around the island.
Housing said there has been resistance to more building, despite areas being identified in the 2002 Island Plan.
Deputy Jackie Hilton told BBC News: "I think it's affected St Clements most, but I'm more optimistic this time.
"We've involved the constables right from the start. They're there to represent their parish and will have a much better idea what is available and what their parishioners are going to think."
In February, ratepayers in St Clement voted against building 56 retirement homes near Jambart Lane, with opponents claiming the parish was overdeveloped.
