The urgency of new quantitative public open space standards in London

The new National Planning Policies Framework (NPPF 2012) in England, requires local authorities to carry out a detailed assessment regarding open space (OS) and to propose new quantitative and qualitative OS standards, based on the new needs of local communities. In particular, the paper examines if and how the new quantitative OS standard (Ha/1.000 pop.) is researched in the 32+1 London Boroughs Open Space Strategies (OSS) and Local Plans (Local Development Frameworks, LDF) (2002–2018). The experimentation with the new quantitative OS standard at local level faces a number of challenges, problems and contradictions. A non-compulsory quantitative standard, in several cases, justifies the reduction in quantity of the Public Green Belt and Metropolitan Open Land. This makes urgent the need to reaffirm the importance of the quantitative component in order to ensure the POS endowment. Based on content analysis of local plans and interviews, this study identifies and discusses local concerns and proposals. Some local authorities propose a minimum reduced quantitative POS standard, equal for all, that could be integrated at the local level by a quota of POS variable in relation to the diverse qualitative requests of the local communities. On this specific topic, London Boroughs’ experience in the current phase of implementation, can offer interesting solutions and remark of general interest.
