Gaudin Creek Wetlands Community Detention Pond, Mission

Start Date: February, 2021
End Date: September, 2024

Gaudin Creek community pond and its associated distribution channel is a gravity-controlled storm water detention system. The system maintains minimum baseflows in the environmentally valuable Gaudin Creek and provides habitat enhancements while accommodating controlled overflow of higher magnitude storm flows into a detention pond to attenuate the peak flow in the downstream creek, thus mitigating the impact of upstream urbanization.

The storm water control infrastructure includes storm sewers ranging in size from 300mm to 1050mm, manholes ranging in diameter from 1350mm to 1500mm, a weir plate flow control device, engineered forebay, rip rap lined swales and overflow scuppers, Newbury weirs, berms, granular access road, pedestrian trail and chain-link fencing, constructed under environmental monitoring.

Wedler has provided lead consultant services and civil engineering design including stormwater catchment analysis and modelling in addition to earthworks and drainage infrastructure geometrical design. Wedler also prepared tender and contract documentation based on MMCD via the City of Mission’s innovative RFP solicitation process and then provided full Contract Administration services and completion records.
