New homes and shops could be built on former school playing fields following an application to change their use.
Blackpool Council has written to neighbours to inform them of potential land use changes on the former Bispham High School site.
The authority said there were no firm plans for the land.
However it has applied for a change of use on the land under regulations which control the disposal of school playing fields.
Residents now have six weeks to comment to the change of use, which would involve part of the site being earmarked for housing and another part being set aside for retail.
A Blackpool Council spokesman said: “There are no specific proposals for the site at this stage.
“However this application would allow a change of use on the land which, at present, is designated as a school playing field.
“The change of use involves both housing and retail space.”
The area covered by the order includes both the main school site and a large area of playing fields.
In a letter sent to residents and seen by The Gazette, Blackpool Council’s director of place Alan Cavill said further feasibility studies would be carried out into how the site could be developed.
Bispham High School, formerly Greenlands High School for Girls, closed in 2015 having merged with Collegiate High School to form Aspire Academy.
Demolition of the main school buildings began earlier this year and a large portion of the site has now been flattened.
Copies of the proposals are available for public viewing at Moor Park Library and Blackpool Central Library.
One the consultation is completed a formal application will be made for Government to approve the change of use.
