An urban stream is an open-ended landscape that develops over time through contact with diverse human and nonhuman users. This project maximizes encounters between species without valuing them according to size, function or taxonomic classification.

A geographical mapping analysis  produced data profiles that evolved  as the design investigation proceeded. Environmental and social conditions change as the city changes. In the Alexandra Stream watershed, intersections between human and nonhuman elements led to the development of pathways, weirs, bridges and rain gardens that can relocate as time goes by.
