The Mid Sussex Development and Infrastructure Supplementary Planning Document (SPD) was adopted in 2006 and relates to policies in the adopted Mid Sussex Local Plan 2004. Since the 2004 SPD was prepared, the Government has published the National Planning Policy Framework (NPPF), National Planning Practice Guidance, and the Community Infrastructure Levy Regulations 2010 (as amended). Each of these documents have set out a new policy context, and provided updated guidance, for the management and collection of developer contributions. Mid Sussex District Council has been preparing a new District Plan 2014-2031, which, on adoption, will replace the Local Plan 2004 as the development plan for Mid Sussex District.
