Most of the field work has now concluded at the landslide site. Geotechnical staff have gathered soil samples for testing and will use that information to compile a computer model of the area. When the modelling is complete, it is hoped that the cause of the slide can be determined and that further remedial recommendations can be made - possibly towards the end of May.

Ten piezometers are now installed at the top of the site to measure groundwater levels. These devices, a risk management measure, will be monitored manually as necessary. We are also working on establishing remote reading capability within the next few weeks. The piezometers complement recent drainage improvements, which include rerouting of natural water courses, and the construction of a drainage basin with overflow facilities at the base of the slope. In addition, District employees, including structural engineers and plumbing inspectors, have worked with homeowners above the slope to address any rainwater drainage concerns.

To date, four homes remain unoccupied.
