Who is responsible for determining the impact and designing to protect against manmade or natural disasters on your home or neighborhood?
A local state of emergency has been declared in a western Manitoba municipality after homes in Ochre Beach were destroyed and seriously damaged by a wave of lake ice.
Area officials told CBC News the wind pushed built-up ice off Dauphin Lake on Friday evening and caused it to pile up in the community, located on the lake's southern shore.
The piles of ice, which were more than nine metres tall in some cases, destroyed at least six homes and cottages, according to the Rural Municipality of Ochre River.
Depending on the hazard, different jurisdictions deal with the issue of responsbility differently. Here's some examples when it comes to development and evaluating hazards (note that there is extensive legislation outlining the responsibilities, this is intended only as a snapshot, not as a guide):
- In British Columbia, it is common practice for proposed subdivisions in steep and hazardous terrain to be required to undertake slope stability assessments. The areas are defined by local governments, but the assessment is the responsibility of the developer's consulting engineer. See Seismic Slope Stability Requirements in BC — UrbanWorkbench.
- In Australia, bushfire risk assessment and mitigation is the responsibility of the developer's consultant working in conjunction with the local government – see FPA Australia | Bushfire Consultants.
- In British Columbia, flood hazard assessment is a multi-jurisdictional responsibility. Lands that may be subject to flooding are identified and rules for development are embeded in the local government's Official Community Plan, but more broadly, flood protection is a provincial responsibility. Meeting those rules, which may include minimum building elevation, emergency access elevations, or other mitigating measures, is the responsibiilty of the developer's engineer.
So who is responsible for mitigating the risk of a 9m high wave of ice blown off the lake in May? Was it even considered when the development was approved?
