In March 2010, the City of Victoria initiated planning for a park renovation and stream daylighting project in Fisherman's Wharf Park. The park was an underutilized playing field adjacent to a popular marina and float home community. The City's and neighbourhood's objectives for the project were to improve the water quality discharging into the nearby Heron Bay, create wildlife habitat, and satisfy the community's desire for a 'natural areas park'.

MDI led an in-depth analysis of several design options that eventually highlighted significantly higher ecological, economic, and community benefits by intercepting and treating the stormwater in a large rain garden park. In contrast, the proposed day-lighting of the pipe running through the park and buried 6 m below the surface, would have led to the creation of a deep ravine – a shady and cool space with steep slopes, poor aesthetic quality and less usable park spaces. The chosen option involved intercepting two shallow storm drains using a source control strategy, avoiding deep excavations and costly soil removal and/or remediation.

In the fall of 2012, Fisherman's Wharf Park was officially re-opened. Today, the 352 m2 rain garden is currently the largest in the City of Victoria and manages the pollution load from the neighbouring community and roads - 14,250 m2 of impervious surface in all. The system allows natural filtration of sediments and pollutants from runoff water before it enters the Inner Harbour.
