Stormwater plan improves fish habitat and water quality
Hollis Creek is in a ravine located on Burnaby's south slope. The watershed is predominantly urbanized with a mix of land use types, from residential to agricultural.
Hydraulic modelling using HYDSYS combined with rainfall and flow monitoring data enabled us to achieve watershed calibration and assessment of various runoff control options.
We used event triggered automated water quality monitoring of the creek to identify improvements required in the collector system and future requirements for improving the runoff quality.
