Dear Jinty,

You will be aware of the widespread concern that despite the Mayor’s opinion the stormwater network infrastructure did play a significant part in the flooding of 3 June 2015. I would tend to agree with that opinion because a close study of the South Dunedin Integrated Catchment Management Plan (ICMP) attached to the 3 Waters Strategy conveys the same impression. The question I have asked myself is this: were Councillors aware of the potential problems before last year’s extreme weather event and could any of you have done more to check that South Dunedin ICMP recommendations were being followed through faithfully by staff with adequate funding by Council?

You will recall being part of the Infrastructure Services Committee that formally endorsed the 3 Waters Strategy in 2010 along with the 10 ICMPs that were attached. On 29 November 2011 I note from the minutes of the Infrastructure Services Committee in regard to Agenda item 6 (3 Waters Strategy Project – use of Integrated Catchment Management Plans) that you personally seconded a motion by former Councillor Syd Brown:

1. That it be noted that 11 stormwater ICMPs had been developed covering Dunedin’s urban-based reticulated stormwater catchments (including Mosgiel)

2. “that the approach proposed regarding the use and management of the information contained within the ICMPs be endorsed”

Motion carried

You may recall from the Staff Report prepared by Tracey Willmott that part of the approach that you seconded to be endorsed was “From an investment perspective – the ICMPs are a tool used to inform and justify the capital and operational investments made by WWS. They propose a series of recommendations over the short, medium and long term and suggest a costed and prioritised programme of work for each catchment comprising of: capital work options, planning options, operation and maintenance tasks or further study.”

So my question is why didn’t you (or any one of your colleagues) think to follow this up by using your right to put this important matter on future Agendas for a review? It is sad that a close inspection of subsequent minutes show no Councillor using the “Notification of Agenda Items for consideration by the Chair” option to formally check on progress with ICMP implementation and particularly the South Dunedin Catchment.

To be fair to Staff the next (and only time) this matter came up on the Agenda was 12 June 2012 under Agenda [item] 4 Stormwater Quality Update. Although this Report majored on quality discharge there were bold statements made eg “we will resolve all known cross connections between the foul and stormwater networks by 2015 etc” and particularly in the Conclusion – “Council has also committed significant funds to ensure that its strategic stormwater management objectives are met and is making good progress with implementation of these Plan”.

So in the light of these promises and the fact that a search of subsequent minutes of the ISC to date show no mention of this issue why wasn’t this most important issue followed up by you and your fellow councillors on the Infrastructure Services Committee?

The chair of Infrastructure Services Committee is Cr Kate Wilson. Cr Jinty MacTavish chairs the Community and Environment Committee. Cr Andrew Noone is the past chair of ISC, and currently chairs the Hearings Committee.

Lyndon is wrong.
The 3 June 2015 Dunedin Flood was NOT an extreme weather event. This was easily confirmed by recognised experts in their fields including a hydrologist (hydrologists use a variety of computational, hydrological and scientific modelling techniques in the research, development and maintenance of safe and sustainable domestic or natural water management strategies) and a meteorologist (meteorologists predict the weather and study the causes of particular weather conditions using information obtained from the land, sea and upper atmosphere; they use computerised and mathematical models to make short and long-range forecasts concerning weather and climate patterns). Historical records have also been referenced to expose the Mayor of Dunedin’s erroneous claim that this was an extreme weather event.
