Laycock Park, Nose Creek, Calgary NE
2006 - Present
Nose Creek and its surrounding riparian area in Laycock Park were experiencing degradation from the pressures of population growth in Calgary. There are a total of 6 stormwater outfalls in Laycock Park, that drain nearly 1,500 hectares from surrounding communities, leading to increased erosion, scour, channel widening, and an increase in te establishment of weeds.
Laycock Park was chosen as the first City of Calgary constructed wetland project where compensation funds would be applied. Through numerous design charrettes and discussions with stakeholders and the community it was determined that:
1) a habitat wetland could potentially be constructed along the northern extent of the park and
2) the re-introduction of meanders into the section of Nose Creek that passes through the park could be feasible.
Over the course of four years, the Westhoff team diligently worked towards completing creative designs for creek meanders. The re-alignment designs required detailed assessment of creek hydrology, flood flow analysis and local geo-morphology investigations yielding a new creek meander system, and a profile with pools and riffles enhancing fish habitat and healthy riparian areas.
The storm sewer trunk system servicing a large catchment area was redesigned to include two very large oil and grit separator units to improve water quality. The design of a instream flow splitting diversion structure allows for intermittent flows to a “vanishing pond” for which the Westhoff Team also completed the structural design.
Westhoff worked closely with local artists as part of the Public Art program, to achieve an interdisciplinary design that recognizes public opportunities and the importance of protecting and maintaining natural areas.
