The relevance of green frontage zones for multifunctional streets

Streetscapes are central in achieving regenerative urban spaces by supporting the urban blue-green infrastructure (BGI) network. The interface between street spaces and private adjacent spaces is central to extending the potential for ecosystem services (ES) provision in streetscapes, but overcoming ownership barriers represents a challenge for urban planners. Although they lie under private ownership, green frontage zones represent a large share of urban spaces and play a key role in creating lively and ecologically beneficial street canyons. The objective of this article is to gain insight into the significance of green frontage zones for the BGI, drawing upon existing literature, and to identify research gaps for further investigations on how to overcome ownership barriers and plan regenerative streetscapes. The results show a lack of clarity of the definition of these zones, a lack of an integrated social, ecological and technological approach and an imbalance in the urban forms covered by existing literature.     «
