Developers can start working on planning applications for 11 sites rezoned for housing that could deliver a total of 450 new homes.

The Environment Minister has published what mix of affordable properties would be considered appropriate for 15 fields in seven parishes.

• La Grande Route de St Jean, St John
• La Route du Nord, St John
• La Rue du Cimetiere, St John
• La Rue des Buttes, St Martin
• La Rue de la Rosière, St Mary
• Le Clos de la Fosse au Bois, St Ouen
• La Rue des Cosnets, St Ouen
• La Route du Manoir, St Peter
• La Route de Beaumont, St Peter
• Le Grande Route de St Martin, St Saviour
• La Grande Route de Jean, Trinity

The planning guidance follows a consultation earlier this 

The sites were earmarked to help address the housing shortage as part of the bridging Island Plan, approved by the States Assembly last year.

The debate was one the longest in a decade and was dominated by discussion of where to build.

Deputy Jonathan Renouf says he regrets how long it has taken to bring forward the guidance, but hopes developers can now submit applications to meet the need for affordable housing.

"I know that in many cases they have got ideas already, and so hopefully this allows them to move forward reasonably quickly with that.  From my point of view, it is a priority that we should get those through the planning system as soon as we can, because we know the need is great."

Deputy Renouf says, in some areas, the island's struggling sewage system will need to be addressed first:

"One of the things that slightly delayed the supplementary planning guidance is that we wanted to be able to give clarity in the guidance about the expected programme of works to bring the sewage system up to standard to be appropriate for those new developments, so that there is some clarity about when those facilities will be available for each site."

Policy for the sites says that the rezoned sites should be 45% for social rent and 55% for purchase, and that those for sale 'must not be sold for more than 70% of the open market first time buyer value equivalent'.
