Genesis Land Development Project
Sage Hill Crossing– Shaganappi Trail NW, Calgary, AB
PRODUCTS USED:
- Geogrid
- TRM - Pyramat
- Coconut Erosion Control Matting
CLIENT: Genesis Land Development Co.
OWNER: The City of Calgary
ENGINEER: Progressive Engineering, Calgary, AB
PROJECT NOTES: This design, supply and install project was completed in September 2007 by Brock White Geotechnical - Calgary. The project involved the design and construction of a mechanically stabilized earth slope to support a major City of Calgary freeway section that encroached on a housing development making a conventional slope impossible.
The tight spacing requirements required either a conventional retaining wall or a vegetated steep slope with a front face gradient of up to 1.6H:1V. The length of the section is 180 m and maximum height is 8 m. Geogrid embedment lengths ranged from 5 m to13 m. The front face was reinforced with a TRM (Pyramat) that was topdressed with loam, seeded and then capped with a 100% coconut erosion matting.
The client was Genesis Land Development Corporation of Calgary with the city of Calgary ultimately taking ownership of the road and retained slope system. The engineering firm
overseeing the project on behalf of Genesis Land is Progressive Engineering of Calgary. The vegetated steep slope system offered considerable savings over a concrete conventional retaining wall while providing a softer landscape for home owners whose properties back onto this section of freeway.
The reinforced soil slope also provides minimal maintenance, is environmentally friendly, reduced heat island effects of hard surfaces like concrete or rock and was quickly installed while working along side earthmoving operations and installation of a major city sewer line.
