A plan which outlines how projects will be estimated to generate project Target Out-turn Costs (TOCs), and how these link into the programme TOC. The first version of this plan was produced on 29 July 2011.

A poster in Kaiapoi showing the estimated timeframe for, and location of, likely residential land developments in Kaiapoi, the wider Waimakariri District and in the rural residential areas, based on major planning and subdivision applications with the Waimakariri Council as at February 2012.

An outline, created in 2011, of the levels of service and condition of the horizontal infrastructure within the central city, providing a broad indication of damage, service levels provided to residents and business owners, and used to estimate the cost of repairs following the earthquake events.

This study updated the 1999 Earthquake hazard and risk assessment study Stage 1 Part B: Probabilistic seismic hazard assessment and Earthquake scenarios for the Canterbury region, and historic earthquakes in Christchurch report. It incorporated new fault data, a new distributed seismicity model and new methods for estimating Modified Mercalli intensities. See Object Overview for background and usage information.

This study analysed liquefaction susceptibility and estimated ground settlements for two earthquake scenarios (foothills and Alpine Fault) for eastern Waimakariri District. The report was later partially superseded by Earthquake hazard assessment for Waimakariri District (Yetton and McCahon, 2009), which while not using such detailed analytical methods as the 2000 Beca report, reviewed new information available since 2000 (including that collected as part of the Pegasus Town development). This showed that the liquefaction susceptibility in eastern Waimakariri district was in fact much more variable than suggested in the 2000 Beca maps, and that liquefaction susceptibility was extremely difficult to predict without a site-specific investigation.

This study led on from Earthquake hazard and risk assessment study Stage 1 Part A: Earthquake source identification and characterisation (Pettinga et al, 1998). It used the location and characteristics of active faults in the Canterbury region, and the historic record of earthquakes to estimate levels of ground shaking (MM intensity, peak ground acceleration and spectral accelerations) across Canterbury for different return periods. The study also provided earthquake scenarios for selected towns and cities in Canterbury, and undertook detailed investigations into the largest historic earthquakes in Christchurch and parts of the Canterbury region. See Object Overview for background and usage information.

The previously unknown Greendale Fault ruptured to the ground surface, causing up to 5 metres horizontal and 1 metre vertical permanent offset of the ground, during the September 2010 Darfield (Canterbury) earthquake. Environment Canterbury commissioned GNS Science, with help from the University of Canterbury, to define a fault avoidance zone and to estimate the fault recurrence interval. There is little evidence for past movement on the fault in the past 16,000 years. However, because of the uncertainties involved, a conservative approach was taken and the fault has been categorised as a Recurrence Interval Class IV fault (a recurrence interval of between 5,000 and 10,000 years). A PhD study by a University of Canterbury student will work towards refining the Recurrence Interval Class over the next three years. Taking a risk-based approach, the Ministry for the Environment Active Fault Guidelines recommend that normal residential development be allowed within the fault avoidance zone for faults of this Recurrence Interval Class, but recommends restrictions for larger community buildings or facilities with post-disaster functions. The report is assisting Selwyn District Council in granting consents for rebuilding houses on or near the Greendale Fault that were damaged by permanent distortion of the ground due to the fault rupture in the September 2010 earthquake. The report provides specific recommendations for building on or close to the Greendale Fault, which are being implemented by Selwyn District Council.
