A developer has published their South Alton Proposals which includes some public consultation on Friday 18th and Saturday 19th May.
Significant parts of the proposal include the relocation of the Sports Centre to the Chawton Gap Triangle, changes to the Butts Bridge and significant numbers of additional housing in the local area - see http://southalton.com/introducton/
For more information, see http://southalton.com/
Its unclear at this time what level of consultation / support exists between Alton Town Council and/or East Hampshire District Council or not. Please note that this is not an official planning application at this point in time.
