Fisher-Hallman Road, Region of Waterloo, ON
Fischer-Hallman Road, also known as Regional Road No. 58, is a north-south arterial roadway in the Region of Waterloo, Ontario, and an important transportation link between the City of Kitchener, City of Waterloo, and the Township of North Dumfries. This vital corridor provides access to the Conestoga Parkway (Highway 7 & 8), the Village of Ayr, as well as numerous business, public institutions, residential communities, and commercial properties.
The Region of Waterloo retained Associated Engineering to complete a Schedule “C” Class Environmental Assessment to improve and widen Fischer-Hallman Road from two lanes to four lanes, between Bleams Road and Plains Road in the City of Kitchener and the Rosenberg Community.
The proposed design includes a fully urbanized, access-controlled, four-lane roadway, complete with a raised centre median, multi-use trails and modern roundabouts at the future Rosenberg Way, Seabrook Drive, Huron Road and future Street ‘1’.
The scope of the Environmental Assessment Study also included the detailed design of a wildlife culvert crossing and upstream floodplain mapping to support the overall drainage strategy of the area.
We reviewed and assessed the existing stormwater management systems in the area against the current and proposed road conditions, the available existing capacity in the existing stormwater management facilities, and, where required, options for stormwater conveyance given site development and topographical constraints.
Related to the roadway works, the project also included the replacement of an existing culvert at Strasburg Creek. Project Manager, Peter Lejcar, tells us, “The culvert design needed to address the Regional storm event while addressing constructability considering the installation of a deep sanitary trunk sewer and by-pass of an existing 450 millimetre diameter PVC watermain in the immediate vicinity of the works.”
As part of the culvert work, we reviewed the existing hydraulic model, which was completed using the HEC-RAS software model. Peter advises, “We modelled and analyzed several hydraulic scenarios to determine the effect of various culvert configurations on the upstream Regional flood limit at Bleams Road, working within known upstream limits and constraints. We sized the new (twin) culvert to address these parameters.”
Construction of improvements to Fischer-Hallman Road and the Strasburg Creek Culvert installation is scheduled to commence in 2019. Key staff involved on the project include Peter Lejcar and Don McBrayne.
