Heads of the Valleys Greenspace Provision Analysis

Client: A consortium of Blaenau Gwent, Caerphilly, Torfaen, Merthyr and Rhondda Cynon Taff County Borough Councils

Over several years Exegesis undertook a number of analyses of Greenspace provision, comparing the results against the standards in the CCW Greenspace Toolkit.Heads of the Valleys Greenspace provision

Data were collated to create a dataset of candidate Greenspaces, an access network dataset and an access point dataset, all of which were checked by local authority staff. A dataset showing population distribution was created from national census data. Analysis was undertaken to determine the distance between each postcode and the nearest access point on the nearest Greenspace. With 14,000 postcodes, 12,000 candidate Greenspaces and 12,000 kilometres of access network this represented a significant data processing task.

Additional analyses were carried out that assessed the slope of each section of the access network and reanalysed the data excluding sections of the access network regarded as being too steep.
