Spatial Vision, supporting E2Designlab, investigated and mapped surface permeability of the flood prone Elster Creek catchment on behalf of several inner south-east Melbourne stakeholders (Melbourne Water, City of Glen Eira, City of Kingston, City of Port Phillip and City of Bayside).
The project established a suitable approach for the protection and enhancement of permeability in the Elster Creek catchment. GIS analysis led to creating a fine-grained, parcel scale map of permeability across the catchment and developing suitable land cover layers of up to 7 surface types, along with a uniform vegetation cover.
The outputs from desktop analysis used permeability equivalence as a measure to achieve council stormwater management and climate resilience policy objectives. The project resulted in a rigorous and repeatable methodology to map existing permeability across urban catchments.
