Natural Hazards Task Force
In October 2007, the District formed a Natural Hazards Task Force.
The task force was comprised of eight volunteer District residents with the mandate to recommend to Council the tolerable level of risk to life from natural hazards.
Information gathering process
The task force received presentations from subject matter experts in the topics of natural hazards, risk assessment models, mitigation methods, financial, and legal considerations. They also sought public input through an open house in November 2007, a public meeting in December 2007, and an online survey.
Adopting risk tolerance
After much discussion and deliberation, the task force recommended to Council in April 2008 that the risk tolerance criteria used in other countries such as Australia, Hong Kong and the UK be adopted by the District of North Vancouver.
Before formally adopting the proposed risk tolerance criteria, Council directed staff to investigate the practical implications of implementing such a policy.
