9.10 Previously developed land (PDL), often called brownfield land, is the land that was developed but is now vacant or derelict, or currently in use but with known potential for redevelopment. The NPPF[1] in paragraph 111 indicates that Local Authorities may continue to consider the case for setting locally appropriate targets for the use of PDL. It also encourages the effective use of land by re-using that which has been previously developed. It is considered that a locally set target is the effective means to secure re-use of land. The mechanism and rationale for the South Somerset Local Plan PDL target is set out below.
