Knowsley, Sefton and West Lancashire Councils are carrying out a joint 'call for sites' exercise.
The councils say the exercise will help to identify land or premises that may be suitable for housing or employment use and will update the authorities' Local Development Frameworks.
Each submitted site will be assessed against various criteria to determine its suitability for development. However, putting a site forward does not guarantee that a council will allocate it or support its development in the future.
The final site assessments, including whether sites are considered suitable for development, will be published later in the year when people will have an opportunity to comment on them.
Any sites put forward as part of the 2007 exercise should not be re-submitted as they will not be reassessed and any sites in the Green Belt will not be considered at this stage.
A separate Green Belt study is being carried out to assess land in the Green Belt for potential future development uses. More information is available here –www.sefton.gov.uk/greenbeltstudy
