- A spatial analytical framework to support landscape planning and urban design practices was introduced in this study aiming to integrate different scales of analysis and their effect when retrofitting Water Sensitive Urban Design (WSUD) in the existing urban environment. The multi-scale analyses are performed using a geographic information system (GIS) platform to capture landscape patterns (spatial structure and composition) and processes (e.g. water cycle). The macro-scale analysis at the urban catchment level allows the development of planning strategies and performance objectives for the urbanized landscape, whilst the meso-scale, comprising the ecological (green) corridors, connects core areas conveying surface flows across the sub-catchments. At the neighbourhood scale, urban form parameters measured the territorial depth (permeability) between public and private land and the suitability of each site to retrofit Water Sensitive Urban Design. The feasibility to improve or extend the existing green-blue landscape matrix is assessed, and its implications discussed, by using a sequence of landscape metrics, land suitability and network analysis techniques. The study focused on modelling opportunities for the introduction of landscape features designed to improve surface stormwater management and, at the same time, provide multiple ecosystem services.
