Beban, J.G.; Coomer, M.A.; McBride, S. 2012 Addressing earthquake hazards : a review of council policies and plans within the Wellington region. Lower Hutt, N.Z.: GNS Science. GNS Science report 2012/31 52 p.

Abstract: This report investigates how various council plans and policies within the Wellington region recognise earthquake hazards. Annual plans, long term plans, district plans, spatial plans and earthquake prone building policies of the following councils were reviewed: Hutt City Council, Kapiti Coast District Council, Porirua City Council, Upper Hutt City Council, Wellington City Council. A content analysis was undertaken of these plans and policies. The results were analysed to determine the various levels of recognition of the earthquake hazard within these plans. This included identifying whether any of the plans or policies had a greater recognition of the earthquake hazard when compared to others. The implications of the results on addressing earthquake hazards were then discussed. The results showed that there was a strong divide between non-rule and rule based policies and plans. Generally, the non-rule based policies and plans (annual plans and long term plans) had the lowest recognition of earthquake hazards. Corresponding with this low recognition of earthquake hazards, these plans and policies also had very few objectives, policies or assessment criteria to address earthquake hazards. The rule based plans and policies (district plans and the earthquake prone building policies) had the greatest recognition of surface fault rupture hazard, with almost all of these documents recognising this hazard. These plans and policies also had objectives, policies and assessment criteria designed to address earthquake hazards. (auth)
