Greater South Dunedin : Public Meeting, Monday 12 June 6.30pm

Public Meeting South Dunedin: It’s your future!
Monday 12 June 6.30pm Nations Church. Please come!

It’s almost two years since the devastating 2015 floods which hit the suburbs of Greater South Dunedin, affecting more than a thousand homes, businesses, community organisations and schools.

It is timely to hold another public meeting in order to give you a voice and to provide an opportunity for some information sharing and discussion about the priorities for our community.
We hope you will attend.

Ray Macleod, Chair
The Greater South Dunedin Action Group

Background Information:

There’s been a lot of talk about the future of Greater South Dunedin.

Some of that talk has been muddled by poor quality information collected and published around the extent and causes of the flooding on our community. Eventually the Dunedin City Council acknowledged that its lack of maintenance of the mud tanks and its lack of oversight of the performance of the Portobello Pumping Station contributed 200mm to the flooding that occurred.

Parliamentary Commissioner for the Environment, Jan Wright, warned earlier in 2016 that South Dunedin presented the “most troubling example” of high groundwater in the country.

The DCC and the Otago Regional Council have produced reports on the flooding and the issues facing Greater South Dunedin due to rising groundwater and the impact of climate change. Their reports are largely based on predictions and modelling assumptions.

There have been reports by GNS Science and the University of Otago’s School of Surveying of potential subsidence in South Dunedin and other parts of the city. At the time, GNS cautioned against reading too much into the subsidence data, as more work was required.

The DCC has finally announced a temporary community hub will open at Cargill Enterprises on Hillside Road mid-year.
After much public outcry, the South Dunedin Work and Income and Police station re-opened their doors.

The DCC formed a stakeholder group of organisations and government agencies, some of whom have a presence in South Dunedin, which meets every month or so.

Heavy rainfall over Easter demonstrated that the City’s civil defence preparedness and response has improved, although local people are yet to be fully informed about how they can be better prepared and understand how a civil defence emergency may affect them.

The DCC’s Second Generation Plan has held hearings into the Hazard 3 (Coastal) Overlay which covers the area bounded by Forbury Rd to the west, Victoria Road to the south, the Caversham bypass motorway to the North and Portsmouth drive to the east. This includes a provision to require new residential dwellings to be “relocatable”.

The DCC also recently announced new “minimum floor” levels for new buildings in South Dunedin of 500 mm for those not affected by the 2015 floods and 400mm above the floodwaters for those affected by the 2015 floods. This will result in some new houses having to be a metre above ground level in order to get a building consent. GIVEN THE DCC CONTRIBUTED 200MM TO THE 2015 FLOOD LEVEL THIS RAISES A QUESTION REGARDING THE NEED FOR ANY MINIMUM FLOOR LEVEL REQUIREMENT OR A CASE BY CASE EVALUATION AS THE NEED ARISES.

If you live or work in the Greater South Dunedin area, all of these proposed changes and approaches affect you. Put together they provide a confusing picture of an important community which is receiving mixed messages about its future and doesn’t yet feel it has a strong voice and a plan.

In all of the discussions about the future of Greater South Dunedin, the people who call these suburbs (of South Dunedin, St Kilda, St Clair, Forbury, Caversham, Caledonian, Portsmouth Drive, parts of Musselburgh and Tainui) home or work are not yet part of the discussions.

You may have attended a public meeting after the floods which resulted in the formation of the Greater South Dunedin Action Group. We consider you to be an important part of this group as it aims to:

• Facilitating effective communication between the community and the city and regional councils
• Advocating, representing and promoting the present and future interests of the community
• Ensuring the area is well serviced by Council in terms of social and infrastructure services as a foundation for a vibrant community
• Exploring the opportunities for the area including inner city redevelopment, renewal, and support for new job opportunities & enterprise
• Developing a sustainable plan for the future of the Greater South Dunedin area and its community

Policy could hold back South Dunedin
By Margot Taylor
Residential property development in South Dunedin could be “squashed” by the Dunedin City Council’s overly cautious natural hazards policies, the Otago branch president of the Property Council New Zealand warns.
Geoff Thomas said a proposal under the proposed second generation Dunedin city district plan (2GP), to require all residential properties in the area to be movable, could stymie the replacement of housing stock. The proposed policy ignored costs associated with residential development, including land, compliance costs and construction materials. “Making residential housing relocatable doesn’t make sense. I, personally, have sold a 1980s house with aluminium joinery for $1 to be moved.” If approved, the proposal would result in either more substandard houses, or houses that would be “very expensive” to build, he said. The natural hazards policies did not adequately consider current and potential technologies to manage sea-level rise and floods. “I think South Dunedin is full of opportunity. A lot of the housing stock is from a day gone by. It is an opportunity to do something with the area and our concern is we don’t want to end up with a caravan park out there.” Water drainage was a clear issue. A more reasonable approach to protect the economic viability of the area could be taken to address it.

Dunedin City Council – Media Release
Home found for South Dunedin pop up hub

This item was published on 02 May 2017

A home has been found for the South Dunedin pop up community hub. The Dunedin City Council this week signed a two year lease to set up a temporary hub in part of the Cargill Enterprises premises at 199 Hillside Road.

[screenshot – click to enlarge]
DCC Webmap – 199 Hillside Rd, South Dunedin JanFeb 2013

Group Manager Arts and Culture Bernie Hawke says, “We are delighted to have a confirmed location for the pop up hub. This is a well known, central location and we look forward to providing a range of services on site for local residents.”

The DCC is leasing about 200sq m, which includes space for community activities, meeting areas, DCC service centre and library activities, and kitchen and toilet facilities. The hub will also provide access to Gig wifi for the South Dunedin community. It is hoped the pop up hub will be open about mid year. As well as providing access to DCC services, the hub will provide an opportunity for the community to have input into the development of the permanent South Dunedin Community Hub. While the opening hours for the pop up hub are still to be confirmed, the hub is expected to be open about 25 hours a week, across five days and including one evening and Saturday morning.

Cargill Enterprises Chief Executive Geoff Kemp says, “Cargills are thrilled to be in a position to accommodate the city’s South D interim hub initiative. “A community centre and library adjoining the main facility will give our 94 staff easy access to the many services planned, particularly the opportunity to explore a wide range of reading material and multimedia. We view the hub as complementing our employer-led numeracy and literacy training programme. Very exciting!”

Mayor of Dunedin Dave Cull comments, “The establishment of the pop up hub shows the Council’s commitment to South Dunedin and is a key part of a much wider engagement with the South Dunedin community and agencies working in the area.”

DCC Chief Executive Officer Dr Sue Bidrose says, “When the pop up hub has been established, we will turn our attention to the location and development of the permanent hub. The signing of a lease for the pop up hub is an important step in this process. In addition to the pop up hub development, our Community Development team has been working alongside groups within South Dunedin to look at the social and economic needs and strengths of this community. As part of this, on 18 May we are organising a number of local community-based groups and individuals to meet to see if a collective action plan to support improved social and economic wellbeing can be created within the South Dunedin area.”

Cracking the truth : June 2015 South Dunedin flood

OPINION received from Neil Johnstone
Sat, 10 Sep 2016 at 12:42 a.m.

Richard Stedman produces (below) a succinct review of the causes of, and failures after, the South Dunedin flood of June 2015. His frustrations appear to match those of Hilary Calvert that were published a few hours earlier. My reviews previously published on What if? Dunedin commencing back around February give more detail.

For your readers’ further consideration, Richard has highlighted the ‘200mm increase’ in flood level as a result of Portobello Road pumping station failures. The figure was derived by me, and appears in my review of the first DCC flood report. To my knowledge the only clear comparable DCC concessions have come from chief executive Sue Bidrose who admitted the figure publicly at the 20 June 2016 (yes, 2016) South Dunedin Action Group-organised public meeting, and subsequently.

The first DCC flood report (30 Nov 2015) is adamant that high groundwater was the cause of the flooding, and enough Councillors bought right into that excuse at the following Infrastructure Services Committee meeting. Just go back and view the video, if you’ve forgotten.

Dunedin City Council Published on Dec 7, 2015
Dunedin City Council – Council Meeting – November 30 2015
Discussion of the report starts at 1:09:52

The second (mudtank) DCC report of 26 April this year states: “Although Portobello Road’s performance did explain some of the length of time flooding was evident, much of the flooded area was below road level…” (para 31). No mention of increased depth of flooding there either, you will note.
[View report at Infrastructure Services Committee: Agenda & Reports 26 April (Part A, Item 5) pp 6-27.]

Neither DCC report mentions the additional depth of flooding caused by inaction at the Musselburgh pumping station.

History and ongoing design may rely on written commentaries. For the wellbeing of South Dunedin people, we must therefore continue to counter the misinformation contained in DCC reports, and in the more recent ORC (DCC-backed) South Dunedin “hazards” report. Even if ODT has switched off.

OPINION received from Richard Stedman
Fri, 9 Sept 2016 at 8:24 p.m.

The ODT editorial department is peopled by closed minds, a number of whom subscribe to the climate change/rising sea level mantra and therefore manipulate their content to support their distorted view of the world. Mr Morris is captured by the former/present regime at city hall, a fate which befalls every reporter assigned to that round once they get their feet under the table.

Two weeks ago I prepared an opinion piece re the election and South Dunedin, outlining some of the issues as I see them in the hope that it might be published. I thought it was honestly held opinion, but it was rejected because it added “nothing new” to the debate, yet they run to Cull at every turn and run column after column of repetitive nonsense.

The following is my submission submitted on 24/8 and rejected the same day in this message: “Thanks for this submission, but we have had a “deluge” of flood letters and op eds from all sides so I don’t feel the need to highlight the issue again at the moment – certainly if there’s not anything new in it, as such”.

I have seen little evidence of the cited “deluge”.

The South Dunedin flood of June 2015 may be a tipping point during next month’s local body election. Many voters will look at the burgeoning candidates list for the Dunedin City Council and ask “who will provide the cornerstone elements of responsibility, accountability and integrity?”

Residents and business owners in South Dunedin have been sorely tested in recent times through the failure of the DCC to maintain its infrastructure. Among those adversely affected were elderly residents at Radius Fulton Home, including a number of dementia patients, the most vulnerable in our community, who were subjected to floodwaters containing sewage and transferred from the safety of their home in a crisis beyond acceptance. Some were accommodated as far away as Balclutha and Oamaru and three months passed before the facility was re-opened.

Following the flood, obfuscation clouded the failures that led to the inundation of homes and businesses and the investigation and report into the affair was 12 months in gestation. Officials and councillors, captured by the twin mantras of climate change and rising sea level, avoided any suggestion of culpability to limit the likelihood of litigation, and offered no solace that might have been construed as admission of liability.

The mayor and others were quick to blame rising sea level causing increased groundwater, combined with an “extreme weather event”, the result of climate change, and went so far as suggesting that a planned retreat from South Dunedin may be necessary in the future. The rainfall was described as a one-in-100-year event then gradually downgraded, but none of these pretexts are realistic. Questions arise over who is responsible for what, and how serious are the threats of rising sea level, more frequent adverse weather caused by climate change, and the “sinking of South Dunedin”, not to mention “retreat”.

Dunedin and environs have been subjected to much larger weather events in the past. Flooding of the entire city is well recorded and in particular photographs of the 1923 flood depict rowing in floodwaters in the city as well as inundation in South Dunedin. During a storm in 1898 large tracts of St Clair Esplanade were destroyed by the sea which damaged many houses, leaving some partly suspended. More recently, the storms of 1968 were greater than last year’s, delivering 10% more rainfall. In 1968 there were 90 properties invaded by floodwater, whereas last year some 1200 properties were flooded and many contaminated with effluent. Clearly last year’s event was exceptional only for the damage created and lives disrupted.

At a public meeting in South Dunedin on June 20, more than 12 months after the event, those affected had an opportunity to hear an explanation in the hope that someone might take responsibility for the extent of the damage. Despite a good representation of councillors there was no empathy and no likelihood of accountability. What the meeting heard was a long explanation of how the three-waters system works, or doesn’t work, as the case may be, and of failure at the pumping station from chief executive, Dr Sue Bidrose and other staff. The question is “when did the city’s councillors abdicate?”

South Dunedin June 2015 [radionz.co.nz]

It can be argued that the damage and distress was the result of neglect, but the DCC says problems at the pumping station added only 200mm to the flooding which would have occurred anyway. Which 200mm was it? Maybe the first 200mm flowed across the ground, reached blocked drains then deepened throughout the area, or perhaps the last 200mm increased the depth and entered homes and business premises carrying undesirable flotsam. Without the extra 200mm would the water have stopped at the thresholds rather than flowing inside?

What of the rising sea level threat? Is it as urgent and as devastating as the commissioner for the environment, some DCC councillors and the Green Party say? The Greens proffer that the Government should help to pay for the reconfiguration of South Dunedin. Why? There has been no disaster on the scale of the Canterbury earthquakes and there is no immediate danger condemning South Dunedin, for if sea level were to rise according to some projections, north Dunedin and other areas are also in jeopardy meaning protection on the coast is futile because the flat land would be inundated from the harbour.

Could it be that models of sea level rise around New Zealand are exaggerated and distorted by the multiplier effect have been grossly over stated? And do the $7 million apartment complex at the Esplanade to be completed next year and the DCC’s belated discussion on a South Dunedin hub indicate mixed messages on the subject?

There is no doubt that the infrastructure must be maintained to the highest level and upgrading implemented with haste. The seafront calls for a level-headed approach to protect the sandhills which shelter the city from the ocean. In the past a network of groynes captured the sand, maintaining a broad beach to dissipate the energy of the waves. The network succeeded for nearly 100 years, but without maintenance fell victim to the ocean, so is it time to reinstate a similar system and then plan carefully for the next 100 to 200 years?

Council says that infrastructure will require “tens of millions of dollars” we cannot afford, but plans to spend some $37 million on George Street and the Octagon, followed by development of the harbourside. These “tens of millions” surely must be re-allocated to South Dunedin for infrastructure, to build a second pumping station, and provide realistic coastal protection.

Dunedin needs new councillors who will make hard decisions, reduce spending on fripperies and attend to basics; people who are prepared to drill deep into reports and costings and who are not afraid to make unpalatable decisions when needed rather than govern with slogans and platitudes.

Declaration: Conrad Stedman is my nephew.

Dunedin City Council – Media Release
Drop-in sessions start of community conversation on South Dunedin’s future

This item was published on 22 Aug 2016

A series of drop-in information sessions hosted by the Dunedin City Council and Otago Regional Council early next month are the start of a community conversation around South Dunedin’s future. The sessions will be at the Dunedin Gasworks Museum on Thursday, 1 September and Friday, 2 September.

DCC chief executive Sue Bidrose will be presenting information about what happened in the 2015 flood, how the current stormwater system works, and how the DCC plans to invest and work with the community in the future.

Ms Bidrose said that it was important to plan carefully for South Dunedin’s changing environment. It was also important to take the time to involve the community in the decision making along the way, rather than to just do things on their behalf.

“Addressing the challenges of the future requires the DCC and ORC starting to have conversations with the community about the challenges, and the expectations and options for what can be achieved. The rest of Dunedin’s population needs to be involved as well. There is a great opportunity to turn some of the challenges into opportunities and give confidence for long-term investment in the area. These drop-in sessions are the beginning of the process. The DCC will be actively seeking local people’s thoughts on these issues and working with the ORC on what the long-term responses might be. I’m looking forward to seeing as many people as possible from the South Dunedin area at the sessions.” –Bidrose [employed by ????]

ORC director of stakeholder engagement Caroline Rowe said the drop-in sessions were part of a wider South Dunedin community engagement plan, aimed at developing a conversation with locals and groups about managing the risks associated with the changing environment. Ms Rowe said they follow the recent release of the ORC’s Natural Hazards of South Dunedin report. The [BULLSHIT ORC] technical report pulls together information and analysis gathered over the past seven years on natural hazards facing the area, particularly the increased likelihood of surface flooding associated with rising sea level. [FALSE AND MISLEADING BULLSHIT]

Presentations, with accompanying video, will be at each session and people will have an opportunity to talk individually to staff from both councils. The hour-long sessions will be repeated several times, with Thursday sessions starting at 10am, 11.30am, 1pm, 4.30pm and 7pm. The Friday sessions will start at 10am, 11.30am, and 1pm.

Ongoing engagement planned for the next few weeks also includes briefings for support service agencies and other specific interest groups such as the South Dunedin Business Association, the Otago Chamber of Commerce, and school and early childhood centres.

Contact Sue Bidrose, chief executive DCC on 03 477 4000.

█ Feedback on the proposal can be provided online on the council’s website at http://www.dunedin.govt.nz/council-online/currently-consulting-on/current-consultations/south-dunedin-community-hub

ODT: South D hub proposal unveiled
The Dunedin City Council is calling for feedback from residents on its preferred option for a library and community hub in South Dunedin before a report is presented to councillors next month. Council services and development general manager Simon Pickford and architect Jon Rennie, of Athfield Architects, presented the council’s preferred option to about 50 people at the Dunedin Gasworks Museum on Saturday morning. Under the $5.25 million proposal, a library would be built in the former BNZ building in King Edward St and the facility linked to the Gasworks Museum through Lorne St. Some facilities, such as a café, would be based at the museum. Mr Pickford said residents had until August 29 to provide feedback to the council on the proposal.

Sessions on natural hazards
By John Gibb
South Dunedin residents will be able to learn more about natural hazards facing the area through drop-in sessions to be held at the Dunedin Gasworks Museum early next month.
The Otago Regional Council is organising the September 1 and 2 sessions, in collaboration with the Dunedin City Council. The drop-in session on the first day will run from 1.30pm to 7pm, and on the second day from 10am to 2.30pm.
Last month the ORC released a report titled “Natural Hazards of South Dunedin”. This report consolidated information and analysis gathered over the past seven years on the natural hazards facing the area, particularly the “increased likelihood of surface flooding associated with rising sea level”.

LGOIMA trials and tribulations with peer reviews #SouthDunedinflood

The following letter has had names removed, except those previously cited by broadcast and print media (public domain). -Eds.

—

Received from Neil Johnstone
Fri, 5 Aug 2016 at 11:41 p.m.

Subject: DCC and the LGOIMA

Message: I have read concerning comments on your site regarding DCC’s apparent failure to comply with its LGOIMA obligations. You may wish to post my account of my recent experience.

[begins]

Dunedin City Council took ten months to produce its second Infrastructure Report, entitled ‘South Dunedin Public Infrastructure During June 2015 Flood Event Follow-Up’ (Author: R. Stokes). On 28 January 2016 (still three months before the report surfaced), then DCC Group Manager Transport Ian McCabe told the Otago Daily Times “the lengthy timeline was needed to ensure the report was robust, including an external peer review of its findings”. Mr McCabe went on to emphasise that “the report had been widened from an initial focus only on mudtank maintenance, and now also included a fresh look at the network’s design capacity”. That all seemed fair enough.

When the report was ultimately released in late April 2016, it contained no reference to any external (or other) peer review. However, when interviewed by John Campbell on Radio NZ’s Checkpoint programme on April 22, shortly after the Report’s release, Mayor Cull repeatedly referenced “independent” peer review(s) as supporting (“parts of”) the Report’s content. Mr Cull stated that he didn’t know which parts of the report had been reviewed independently. “You would have to talk to her (Ms Stokes) about that,” he said. Presumably, therefore, he hadn’t seen the review(s) either.

On 17 May I sent a LGOIMA request to DCC Chief Executive Sue Bidrose, asking for a copy of the review(s). On 20 May I received an acknowledgement from DCC which rather defeated the purpose of my request but, more importantly, indicated that I would receive a response asap, but within 20 working days. I immediately queried why it should take such a long time to simply send a copy of a recent review, and asked simply for confirmation whether the review actually existed.

This time I received an email from the Group Manager Corporate Services suggesting a “discussion” before they left for overseas. There was no mention of my straightforward query as to whether the review actually existed. I replied immediately, and asked again for a simple yes/no to that question. Again, the question was not answered.

A full month (the maximum allowable period of 20 working days having elapsed since my simple request) later, I received an email from DCC. They were able to report that they had received information from the General Manager Infrastructure and Networks thus: “The response to Mr Johnstone is that we have had a peer review done, however this is still in draft and yet to be finalised (as staff have been focusing on forward work demands, and we have staff away). Once the review is finalised it will be publicly released.” “Therefore we have decided to refuse your request under section 17(d) of the Local Government Official Information and Meetings Act, as the information requested will soon be publically (sic) available.”

I considered that response was unsatisfactory. The review, apparently under belated construction, was clearly not what I had repeatedly requested. I should by then have received the review referenced by Messrs McCabe (“external”) and Cull (“independent”), or received an acknowledgement that it did not exist.

Then on the evening of 6 July I was emailed by the General Manager Infrastructure and Networks, a copy of a new review, seemingly hot off the press, and authored by Opus in Auckland. This obviously was not the review that I had requested back on 17 May, as all DCC personnel involved should have known.

On 9 July I wrote to Chief Executive Sue Bidrose, expressing my concerns. I asked the following key questions:

Why, almost two months after my original LGOIMA request, I had still not received an admission that the peer review sought did not in fact exist?
Or, alternatively, if it did exist, why had it not been provided?
Why it took a month after my initial request for me to be merely told (irrelevantly) that a (different) peer review was being prepared, but with no attempt to satisfy my simple, legitimate request?

Almost a week later, a DCC officer returned to the list of respondents. They advised that my (follow-up) enquiry was being treated as a new request, and (you all know the drill) would be dealt with as soon as possible, but within 20 working days of receipt at the latest.

Nineteen working days later I received an emailed response from a Manager Civic and Legal. None of the three questions (above) were answered. They stated that my enquiries had been answered as soon as possible, given the volume of other requests. But the most interesting part of their response reads as follows: “The reported reference in the ODT (Mr McCabe, cited 28 January) to the external peer review was actually a reference to work the Council was undertaking to investigate the performance of the mudtank maintenance contractor…..”

So external means internal in the DCC, and widening means narrowing?

If the manager had been informed correctly, then there was no external review. Why, in that case, was I not told that nearly three months ago? Why did the Mayor apparently believe there was an external (independent, to use his wording) peer review? Furthermore, why did DCC fail to answer my three questions above.

I could, of course, ask these questions of DCC via LGOIMA, but I could then only expect an interim response followed by 20 more working days of inaction and worse.

Instead I have initiated a series of complaints to the Ombudsman, and decided that the public should view yet another example of how our City Hall is operating.

My intent throughout has been to identify the true causes of the June 2015 flood, so that real solutions can be identified and “political” solutions avoided. I have no intention of stopping, despite DCC’s apparent resistance.

Neil Johnstone is welcome to publish emails supporting his story; it appears most if not all of the emails he received pertain under the Local Government Official Information and Meetings Act and therefore reside in public domain. However, the Ombudsmen are best to advise on these matters. In the meantime DCC is welcome to correct any factual errors, in the interests of accuracy and balance. -Eds.

Labour messing with South Dunedin, like Cull, unbidden

Not Listening [octavehighereast.com]

—

There is little or no RISING GROUNDWATER at South Dunedin – this is an attack on the local community by Anthropogenic Global Warming (manmade climate change) believers like Curran, Clark, and Cull.

So-called ‘authorities’ are running their Politics over the top of the local Community, Failing to canvass the views of the local residents, property owners, service providers and businesses through agreed consultation methods Before pronouncing upon the area. This is disrespectful, dangerous behaviour. Unwarranted.

A lot of us will remember Labour MP David Clark’s importune speech on climate change at the public meeting held at South Dunedin on 20 June. He completely didn’t register the mood and understandings of the local audience.

Greenie Cull and the Labour Party are deliberately or inadvertently using South Dunedin as a Political Football. There are few votes to be earned from bullying and interference, thank god.

Listening —what is that.

Speaking after the tour, Mr Little said the area was a “prime candidate” for urban renewal under the party’s proposed Affordable Housing Authority.

Labour timeline for South renewal
By Timothy Brown
South Dunedin’s renewal will be showing “good progress” within six years of electing a Labour government, party leader Andrew Little says. Mr Little toured South Dunedin with Dunedin Mayor Dave Cull, Dunedin South MP Clare Curran, Dunedin North MP Dr David Clark and list MP David Parker after the area was earmarked by the Opposition as one urgently needing urban renewal. The group walked from Bathgate Park School, in Macandrew Rd, down Loyalty St into Nicholson St and on to Nelson St before returning to the school. They were accompanied by members of various social groups from South Dunedin.

Labour leader tours South Dunedin
Labour Leader Andrew Little has visited South Dunedin today, alongside a contingent of MPs and social service agency stakeholders. The group wandered around the areas hardest hit by last year’s floods, looking at the handful of houses still empty more than a year on. And Little took the opportunity to offer up his party’s plan to fix some of the issues.

Johnstone disputes Opus review #SouthDunedinFlood

### ODT Online Thu, 7 Jul 2016
Flood review clears DCC staff findings
Dunedin City Council staff have been vindicated by peer reviews which backed their findings over the cause of last June’s devastating floods. The reviews, carried out by infrastructure consultancy firm Opus, backed the council’s findings South Dunedin and other parts of the city would have been flooded even if the city’s stormwater system was running at full capacity.

A truly independent inquiry into the council’s performance around last year’s South Dunedin floods remains long overdue, writes Dunedin engineer Neil Johnstone.

Opinion: Report skims surface of South Dunedin flood saga
By Neil Johnstone
OPINION Readers of the Dunedin City Council-funded independent peer review of its post-flood reporting (ODT, 7.7.16) should be wary. The council’s delight with the review may prove short-lived. In brief, the Opus review:

● Recognises the 1968 rainfall event was bigger than that of June 2015 (contrary to repeated council claims).
● Fails to explore the reasons why the 2015 flood was a disaster, and the 1968 event was not.
● Makes assumptions about groundwater levels without referencing the actual data.
● Appears to consider the council’s assumption of zero ground infiltration has merit (note: the data disproves this).
● Believes mud-tank blockage impacts of the flood were “localised” (too bad if you were a local), but fails to consider the likely widespread impacts on South Dunedin of blocked mud-tanks in the St Clair catchment.
● States council reviews “suggest” its failures at the Portobello Rd pumping station caused an increase in flood levels of about 200mm.
● In fact, the first council review leaves the reader with no more than an opportunity to infer this, while the second council review only states that the failures may have influenced “the length of time flooding was evident”.
● I do not recall the council actually publicly admitting the 200mm figure before the South Dunedin Action Group meeting of June 21.
● Fails to address the flood impacts of the council’s total failure to operate its Musselburgh pumps for stormwater relief.
● Makes general statements to the effect that “primary” flooding would have occurred under any circumstance. South Dunedin residents know that “overwhelming” of stormwater infrastructure was not the concern; the avoidable flooding of our people’s houses and businesses was.

For all of the above reasons, and more, the Opus finding the council report’s conclusions were “robust” is concerning. A truly independent inquiry into the council’s performance pre, during and post-flood, at staff and political levels, is long overdue. ODT Link

Dunedin council concedes flood worsened by faulty pumping station
By Ian Telfer in South Dunedin
Dunedin City Council has admitted a faulty pumping station made last year’s South Dunedin flood 20cm deeper than it would have otherwise been. The Council made the admission at a rowdy public meeting at the Nations Church last night about the flooding a year ago which damaged 1200 homes and businesses. Chief executive Sue Bidrose […] made a major concession, saying the council now accepted a key pumping station was blocked, adding an extra 20cm of water to the area. […] Shortly after the flooding, Mr Cull linked the event to climate change and warned South Dunedin may have to beat a managed retreat. Local woman Kathinka Nordal Stene said she was shocked Mr Cull undermined the community at the time when it most needed his support. She said the future of South Dunedin had become a major election issue, on which Mr Cull would be judged. Mr Cull was not at the meeting because he was visiting China. […] Leaders of the newly formed South Dunedin Action Group accused the council and its leaders of having a secret plan to abandon the suburb and blame it on climate change.

Candidates using flooding for political gain
A heated public meeting earlier this week brought last year’s South Dunedin floods back to the fore. The discussion around what to do for those still affected is one that members of the Dunedin City Council’s executive say they’re taking seriously. But there’s concern some involved parties are using the situation for political gain.

Malhereusement! Ceci est du jeu de puissance ineptes, d’elle-même

Anger about South Dunedin’s future
By Vaughan Elder
Unanswered questions about the long-term future of South Dunedin and the city’s response to climate change loomed large at a heated public meeting last night. Residents concerned about the risk of flooding during future rain events were among about 170 people who packed the Nations Church for the meeting organised by the South Dunedin Action Group (SDAG) and attended by councillors and senior staff members. Attendees heard about the short-term measures the council had taken or was about to take to ensure South Dunedin’s infrastructure would run at full capacity should there be a repeat of last June’s devastating flood.

Oh hurrah. What the council has been doing in planning annual expenditure on pet projects in the interests of some private groups, not Core 3-Waters Infrastructure for South Dunedin:

“She said next year the council would invest $5m in South Dunedin’s community hub, $500,000 in a local hockey turf and more money to buy buildings to expand the area’s Gasworks Museum.” (via RNZ)

The Council made the admission at a rowdy public meeting at the Nations Church last night about the flooding a year ago which damaged 1200 homes and businesses. South Dunedin residents have been waiting for a year for its council to front up for the flooding – and last night it did so en masse. At least eight city councillors, the chief executive and her two deputies were quizzed by 200 locals about what happened last June, and what will stop it happening again. […] But it will take more than [the chief executive’s] words to sort out the ill feeling with residents, who said they felt neglected and betrayed by the council, and especially by Dunedin Mayor Dave Cull. Shortly after the flooding, Mr Cull linked the event to climate change and warned South Dunedin may have to beat a managed retreat.

ODT: ‘Significant benefits’ for city in pipeline
DCC Asset and Commercial Manager Tom Osborn says old cracked earthenware wastewater pipes, mostly laid in the 1900s, have been allowing groundwater to enter the wastewater system, leading to flooding after heavy rain, resulting in overflows. “This also adds to flooding in areas such as the northwest corner of South Dunedin, when pipe flows coming from Kaikorai Valley meet flows from other parts of the city and flatten out, creating a bottleneck effect.”

DCC media release: Kaikorai Valley works enter new phase

South Dunedin stormwater pipes —getting past the desktop ICMP

Dunedin City Council (website) on Stormwater:

Stormwater is rain or snow runoff that does not soak into the soil.
When an area is developed, stormwater generally increases due to runoff from impermeable surfaces (eg roofs, roads, carparks, or compacted soil). It flows naturally from higher to lower ground, and ultimately discharges into natural watercourses such as wetlands, creeks, rivers or the sea. Land development results in the creation of both private and public stormwater systems, which collect and transfer stormwater to lower ground more efficiently. The public stormwater system is a network of drains, gutters, pipes, mud tanks, detention ponds, stormwater reserves and other associated infrastructure.

—

At other threads (here and here), contributor JimmyJones has cited the South Dunedin Integrated Catchment Management Plan (ICMP) to draw attention to the actual or perceived state of the stormwater pipes at South Dunedin. He believes the type of pipeways and the deteriorating condition of the pipes contributed to the June 2015 South Dunedin “flood event”, and will require budgeted upgrade.

But is the South Dunedin ICMP correct about the underground pipes and their condition?

Largely, the ICMP was a desktop assessment carried out by consultants for the Dunedin 3 Waters Strategy. Namely, Opus International Consultants and URS New Zealand (now trading as Aecom) in association with Dunedin City Council.

South Dunedin ICMP – Integrated Catchment Management Plan
● Sth Dunedin ICMP (PDF, 11.1 MB)
● Sth Dunedin Mapbook (PDF, 12.0 MB)

Read more about the 11 ICMPs for Dunedin here.

DCC says ICMPs are used for planning and management of the stormwater system. For each stormwater management area, or catchment, issues are identified and prioritised, and solutions are identified and implemented. The ICMPs are mainly in the metropolitan Dunedin area (including Mosgiel and Port Chalmers). They inform investigation and planning decisions and help focus council priorities for future operational and capital works. Implementing the ICMPs is also a key requirement of DCC consents to discharge stormwater into the coastal marine area. Further information is available on the Stormwater monitoring page, see also the Stormwater responsibilities page.

The Pipes at South Dunedin
Local water and drainage experts familiar with the stormwater system say:

Received.
Sat, 18 Jun 2016 at 10:52 a.m.

The South Dunedin ICMP report has been read, it’s “ok”. But it’s also described as “…glossy and costly for the consultant(s). Basically, such reports tell the Council stuff they neither read nor understand, but would have mostly been trivial knowledge (where accurate)” to local experts familiar with the design and day-to-day workings of the stormwater system.

“You can believe any part of [the ICMP] or not. It’s a desktop study, which speculates on pipe condition. Robinson and Hendry have read it and obviously don’t agree. Pipes last for an eternity with limited maintenance (other than blockage removal) provided there isn’t ground movement or corrosion (these pipes are concrete).”

“Mr Hendry believed South Dunedin’s infrastructure, which he spent six years helping build as a surveyor in the 1960s, would have been good enough to prevent much of the damage had it been properly maintained. […] My view is that these people out here, a lot of them have got nothing. Now they have got a hell of lot less. It’s not fair on them. Nobody’s come out and said ‘we were wrong. Something wasn’t done right’.”

whatifdunedin:

1. The claim of “factual errors” is surely able to be substantiated or thrown out by a suitably qualified (named) EXTERNAL peer reviewer acceptable to DCC and engineer Neil Johnstone. The ‘matter of degree’ (serious ?) is a matter for the peer reviewer to comment on. As are issues of professional competencies —which only an independent and transparent peer reviewer with nationally recognised engineering expertise can deal to. Not an in-house operational.

2. Neil Johnstone has issued three reviews, two of these deal to DCC’s formal reports on the June 2015 South Dunedin “flood event”, dated 30 Nov 2015 and 26 Apr 2016 respectively; and the third deals to comments (video recorded by Ch39 and published at DCC’s Youtube channel) during the DCC Infrastructure Services Committee meeting held on 26 April 2016. The reviews are published at this website – enter the term *johnstone* in the search box at right.

3. Neil Johnstone has requested that factual errors noted by DCC be made discoverable. DCC appears to be side-stepping qualification and quantification of its verbal assertions every which way.

4. It is highly likely that no expert external peer reviews exist or they would have been made public by now. More than a year after the “flood event”, we wait.

5. A peer review(s) is not something to hide. Why is DCC doing secret squirrel when challenged to substantiate its earlier comments (publicly stated on more than one occasion, recorded by mainstream media – for example, by Mayor Cull and Transportation’s Ian McCabe, who later resigned) – that external peer reviews of its formal reports did happen. After the fact is a little squiffy, if DCC is writing them now.

“Technical qualifications and experience with stormwater infrastructure design and management” are not provided. Rhetorical.

Holes being dug, an epitaph.

“Civic administration” reacts to hard hitting Listener article

Election Year. This post is offered in the public interest.

S o u t h • D u n e d i n • F l o o d

Truth and decency are owed to the flood affected people of South Dunedin.

Interpretations post flood and in the months since —appear without technical evidence, making false claim to Climate Change (the ‘end is nigh’ if only to avoid local government liability), in contradiction to data and analysis provided by local engineers, ORC, MetService and former council staff, amongst others.

[post] Listener June 11-17 2016 : Revisiting distress and mismanagement #SouthDunedinFlood

‘Our leader’ is in a self-flagellating hole —prepared to say anything to attract votes in the October local body elections. Serious ? Genuine ?

We owe it to ourselves.
The Mayor of Dunedin should not get a third term.

‘Leadership’ has involved neglect of core council business – specifically, maintenance of key infrastructure network and services.

This has done too much damage: tens of millions of dollars of damage at South Dunedin. A massive hit sustained by constituents and insurers. Yet today ‘the administration’ rattles and unsettles the community it has comprehensively failed, with latest wanton burble at the opinion pages of the Otago Daily Times.

The Mayor should immediately resign his office at Dunedin City Council.

Bullshit from the Mayor and underlings is UNACCEPTABLE.
South Dunedin has a stormwater system that when properly maintained is well able to take rainstorms equivalent to that experienced a year ago.

Systems can always be improved but the current stormwater system is not all that old and has been designed with sufficient control mechanisms and stopgaps.

The Administration failed (for years) to deliver on budget, contracts, drain and mudtank maintenance; failed to check pump performance and screens at pumping stations during the June 2015 storm event; as staffing changed, failed to set in place procedures for weather events; failed to understand Civil Defence requirements for the most densely settled suburb of Dunedin; failed to adequately consider storm run-off from surrounding hill areas and the increase of impermeable surfaces as The Flat developed; failed to release stormwater to the ocean, etc etc……. but ultimately FAILED to put proper thought and planning to AVOIDANCE of Endangerment to the lives, health and livelihoods of thousands of South Dunedin residents.

Seriously. That’s the sort of ‘care and concern’ the gold-chained opinion-writer represents at ODT today. Further, there are Absolutely No Grounds to grease up the loophole backside of the technically inexpert Parliamentary Commissioner for the Environment.

The Listener article raises the issue of “mismanagement” during the rains of early June 2015. The liability rests at council doors.
That is a hammering public fact.

Johnstone review following DCC Infrastructure Services meeting 26.4.16 #SouthDunedinFlood

Election Year. This post is offered in the public interest.

B A C K G R O U N D
On and about 3 June 2015, South Dunedin was severely affected by stormwater flooding – the Council has since discussed why and how council-owned infrastructure failure occurred. The extent of stormwater damage to private property and the upheaval and distress for affected residents, property investors and businesses is undeniable. Council operationals refer to this as the “June 2015 Flood Event” in formal reports.

A public meeting coordinated by Dunedin South MP Clare Curran was held at South Dunedin on Monday, 7 March 2016. At the meeting the South Dunedin Action Group(SDAG) was formed. Group representatives headed by spokesman Ray Macleod have since met with the Mayor and council officials – the first meeting was held on Tuesday, 3 May 2016. A meeting with council staff has followed more recently.

Local media, the Otago Daily Times and Channel 39, are presently covering the anniversary and aftermath of the “flood event”. Noticeably, the city council has yet to formally apologise to all the many people affected by the lack of council-owned infrastructure maintenance and stewardship at South Dunedin during the rain event of June 2015.

Council ‘not liable for flood damage’ (ODT 27/11/15)
“The Dunedin City Council says it is not liable for private property damage caused by the South Dunedin flood, despite admitting problems with its pumping network prolonged the pain for residents …. The issue had been considered by the council’s lawyers and insurers, but the advice from both was the council was not liable, [council infrastructure and networks general manager] Mrs Stokes said.”

SOUTH DUNEDIN FLOODING JUNE 2015
A Follow-up Review subsequent to DCC Infrastructure Services Committee meeting 26 April 2016

By N.P. Johnstone, MIPENZ

DCC has produced 2 reports on infrastructure performance during the flooding that reportedly entered approximately 1000 houses and caused in excess of 100 million dollars of damage. I have previously produced 2 independent reviews that are highly critical of DCC’s Stormwater Infrastructure Report (November 2015) and its “follow up” (the “mudtank report”, April 2016).

I also attended DCC’s Infrastructure Services Committee meeting on April 26, and have sighted video recordings of that meeting, which were belatedly posted by DCC close to a month later. I have formed an opinion that DCC has not fully acknowledged its role in failing to prevent much of the flood damage, but (often unreasonably) blames external influences and alleged historical design deficiencies.

I had originally intended to present a blow by blow comment on proceedings of the meeting, but that has proved a bigger task than my time allows, and would probably prove as tedious as the meeting itself. I have preferred not to align statements with the individual staff or councillor that made them, but the reader can view the recording of the meeting at leisure. I can however, not resist the temptation to present the comments of one councillor who stated: I am heartened by how well staff have responded to the challenges…and we can be comforted, I think by the feeling that you are treating our assets like you would your own. South Dunedin residents who had their assets ruined might see things rather differently.

1. THE FLOOD EVENT OF MARCH 8/9 1968
The rainfall event of March 1968 was of the order of 10% greater than that of June 2015, on any comparison. This is incontrovertibly clear from readily available data, and thus demonstrates that the much greater flooding in the recent event should not have happened. DCC has consistently underestimated the significance of the 1968 rainfall.

2. PRE-EXISTING GROUNDWATER LEVELS
DCC has misinterpreted ORC reporting that groundwater levels prior to the onset of rainfall were significantly elevated. DCC has extrapolated this error to claim that no infiltration of rainfall into the ground was possible, thereby explaining away the record surface flooding. ORC’s data is readily available, and demonstrates that groundwater levels only started to increase in concert with the June 3 rainfall, proving that infiltration was both significant and (probably) normal.

3. RAINFALL SIGNIFICANCE
DCC, relying on superficial analyses of other agencies, have claimed that the 24-hour rainfall experienced in June 2015 was a 150-year event, then 100, then 60, then 100 again. The selection of 24-hour duration rainfalls is not entirely appropriate (being rather too long). Nevertheless, the March (or April) 1923 24-hour rainfall was much greater, the 1968 rainfall slightly higher (but ignored in analyses), and at least 2 others between the 1890s and late 1920s were similar, and possibly slightly lower. Analyses of shorter duration events would likely further reduce the assessed recurrence interval of the June flood. I believe it was a 30-year rainfall event at worst.

4. LANDUSE CHANGES
Increased impermeable areas have certainly increased runoff rates; based on DCC-supplied estimates of changes, I have estimated that these changes could have increased flood levels by up to 150mm. Ex-DCC engineers have expressed doubt as to the degree of landuse change. In any case, I would have expected additional stormwater infrastructure to have been installed to compensate.

5. MUDTANK BLOCKAGE
The degree of blocked mudtanks across the catchment was underestimated by DCC, until the release of the mudtank report in April 2016. The extent of the mudtank issue was finally confirmed then, at no great surprise to South Dunedin residents. An unseemly blame game ensued, and may not be over. DCC then took the stance that the plethora of blocked mudtanks had no impact on the depth of flooding across South Dunedin, but may have prolonged the flooding. The claim defies reason, and in part relies on DCC’s adherence to the zero infiltration myth.

6. PORTOBELLO ROAD PUMPING STATION
The partial blockage – and difficulties experienced in the clearing – of the screens at this pumping station has been well publicised, and may have added approximately 200mm to the depth of flooding. Less well publicised are the facts that no emergency staff visited the pump station until about noon on the day of the flood, and (apparently) only attended the station to attempt clearing the screens between visits to other locations during the latter part of the day. Equally poorly understood is that not all of the station’s pumps were operating throughout the flood event due to the manner in which pump cut-ins were programmed. No decision to override the pumps’ programming was made. No information on which pumps remained inoperative has been made available, so it is not possible to attribute the depth of flooding caused by the inability to clear screens, compared with that caused by poor pump management.

7. MUSSELBURGH PUMPING STATION
This pumping station has the ability to bypass the wastewater treatment plant and discharge sewage-contaminated stormwater directly to the ocean at Lawyers Head. The option was not taken in the June 2015 flood. By contrast, in the 1968 event the pumping option at Musselburgh was fully utilised to the extent that approximately 5m³/s was pumped to the ocean for a period of 24 hours. Such pumping would have proved effective as long as individual property gully traps were submerged by stormwater, and may have reduced flood depth by more than half a metre. It is not known (by me) whether a comparable benefit could be achieved under June 2015 conditions, but a very significant opportunity was apparently lost. No information on the Musselburgh station’s pumping operation in the June flood is included in either of DCC infrastructure performance reports.

8. INFRASTRUCTURE DESIGN LIMITATIONS
DCC has relied heavily on the belief that the stormwater system can only handle rainfall intensities of 4.1mm/hr, and therefore regular flooding cannot be avoided. This is contrary to historic reality. The 4.1mm/hr limitation only applies if DCC’s assumption of zero infiltration applies. The assumption has no validity, and the existing infrastructure is far more capable than DCC is stating.

9. EXTERNAL PEER REVIEW
One of the main reasons for the extraordinary delay in the presentation of the “mudtank” report was that a robust external peer review was to be obtained. Reference to such peer review has surfaced occasionally since, but no review has been published. I have sought a copy of any such review – or even confirmation of its existence – from DCC. No such review has yet been confirmed to exist.

10. INFRASTRUCTURE SERVICES COMMITTEE MEETING
Many of the above topics were discussed to a greater or lesser level of detail at the Committee Meeting on April 26. From sitting through the majority of the meeting and viewing video coverage of it later, it became apparent that Councillors’ understanding of the June 2015 flood causes was generally weak, and that many of their questions directed to staff were inadequately or confusingly answered, if they were answered at all. These included:

10.1 Pre-existing Groundwater Levels
Selective reference was made to ORC report text, but no data was referenced. The data disproves the assertion of high groundwater and zero infiltration.

10.2 Mudtanks
According to staff, mudtank blockage didn’t increase flood levels, yet a raised vegetable patch could.

10.3 Portobello Road Pumping Station
No information on unused pump capacity or its impact on flood levels was given (or sought); and the final word on the subject was that the only issue at the station had been debris blockage, now fixed.

10.4 Musselburgh Pumping Station
In response to a question re pumping rates at this station, the reply was to the effect that “we have no data on this, is there a follow-up question?” There wasn’t a follow-up question on the subject, despite its fundamental importance.

10.5 Infrastructure Design Limitation
The existing infrastructure was repeatedly deemed to be inadequate on the basis that only 4.1mm/hr of rainfall could be accommodated, once pipe storage was exhausted. There was no proviso given that this determination required the impossible condition of zero infiltration of rainwater into the ground.

This review does not exhaust my concerns with the technical presented at the meeting, but I can conclude the following with confidence:

i. Maintenance prior to the flood was inadequate;
ii. Emergency management during the event was poor;
iii. DCC’s understanding and reporting of flood issues remains unconvincing, especially without the benefit of promised external peer review.

ONE YEAR AFTER THE JUNE 2015 FLOOD EVENT………………
“D for prolonged distress”

### ODT Online Fri, 3 Jun 2016
In limbo, sleeping in car (+ video)
By Vaughan Elder
A Green Island mother’s “nightmare” since last June’s flood has culminated in her being separated from her son, homeless and sleeping in her car. Tina Conway has pointed the finger at Dunedin City Council for her plight after staff repeatedly failed to discover a council mains pipe was leaking water on to her property, causing a bank to slip away in the June 3 Dunedin floods. It was almost 10 months after the floods and only after the Earthquake Commission (EQC) called in a private engineering company that the council fixed the pipe at the end of March.

An Independent Review of DCC Report : ‘South Dunedin Public Infrastructure Performance during June 2015 Flood Event Follow up’

By N. P. Johnstone, MIPENZ

1. This review complements my peer review of DCC’s first flood report, published in November 2015. This review assesses the content of the second report (described henceforth as “the report”) published in late April 2016, and contextual statements made elsewhere by DCC staff and elected members. The author of the report is Ms R. Stokes. The technical qualifications and relevant experience of the report’s author are not stated.

2. I consider that there is a need for such a review for reasons of historical accuracy and context, the identification of solutions (which can only be achieved be if the problem is understood and acknowledged) and – most importantly – to provide a considered assessment of what South Dunedin’s current flood risk really is, noting that two events (of which only the recent one caused major inundation) in five decades does not suggest a current flood risk much different from that existing in many other established New Zealand communities, despite some landuse changes. It is emphasised that the flood had nothing to do with climate change, nor therefore does this review. The failure to understand the issues may lead to inaction or to inappropriate and expensive actions.

3. This review may be criticised for being repetitive on some issues, but the repetition is at least partly driven by the number of times challengeable information on the flood event and its causes has been circulated by DCC. In many respects, the report under review could be seen as a concentration of such challengeable information. The report is solely based on my research, knowledge and experience; any errors are therefore mine, but hopefully, few.

4. This review has led to the following conclusions:
4.1 Council’s continued insistence that the June 2015 rainfall event was the largest since 1923 remains erroneous;
4.2 Pre-existing groundwater levels were unexceptional, and had no impact on the flooding, contrary to claims made in the report, previously and subsequently;
4.3 South Dunedin does not have a significant imminent exposure to stormwater flooding. This finding is based on the original design parameters, historical performance, an absence of groundwater issues, and provided existing infrastructure is properly maintained, monitored and operated;
4.4 Problems at the Portobello Road Pumping Station caused elevated flood levels and prolonged the period of inundation, but the report acknowledges only the latter;
4.5 Similarly, the now-admitted failures to ensure that mudtanks were properly maintained impacted adversely on flood levels attained in some locations at least, and prolonged the period of inundation in many areas;
4.6 Comparisons with the 1968 flood event can be instructive in assessing the impact of Council failures in 2015 in terms of water level, disruption and cost. The report fails to make such assessments.

5. My review of the first report, written by Ms L. McElhone, was driven by DCC claims that the prime causes of the flood were high sea and ground water levels, a 150-year, then a 100-year, then a 63-year (and incidentally and extraordinarily now again a 100-year*) rainfall event, and confirmed that Portobello Road pumping station issues added not less than 200mm to peak flood levels. That review also demonstrated that the rainfall event of March 1968 was demonstrably larger than that of June 2015, but caused much less damage, and that land use changes added up to 150mm to flood levels (based on DCC’s unconfirmed data on impermeable areas). Any consented landuse changes should, in my opinion, have been compensated for in past years with additional infrastructure to maintain drainage standards and South Dunedin’s protection standards.
(*Ms Stokes to John Campbell on Checkpoint, 21 April 2016).

6. Exaggerated assessments of both the historical significance of the 2015 rainfalls and groundwater levels, and the absence of mudtank information originally helped DCC promote its position of zero liability. The mudtank maintenance failures are at last largely revealed in the new report; significant mudtank maintenance issues were previously reported by Cr Lee Vandervis as early as 2014, but were seemingly largely ignored by DCC. Paragraph 37 of the report which reads: “Mudtank maintenance and performance in general has been the subject of focus for a number of years”, appears vague, and therefore requires elaboration. The statement, if accurate makes the failures more disturbing. There is still some unfortunate reliance on the groundwater myth (paragraphs 2 & 32), and to the underestimation of the 1968 event (paragraph 20). There appear to be newly-entrenched positions at DCC that the existing stormwater system is inadequate, presumably based on the report’s paragraphs 23-27, and reinforced in recent public statements from Ms Stokes and Mayor Cull, that the flood would have occurred (or that a serious flood would have occurred) even if the current system including the mudtanks had operated at optimum. This review strongly disputes such claims, and uses the well-documented event of March 1968 as a very useful “model” for key comparisons between a contained flood (1968) and a disaster (2015).

7. The general understanding was that DCC’s second review was to concentrate in detail on the performance of mudtanks, and was to be peer reviewed. Detailed reporting and peer review processes were understood to be the reason for the extraordinary delays in publication. In reality, only paragraphs 33-61 deal with mudtanks issues and no peer review is included. It is noted that Mayor Cull confirmed to John Campbell on Radio NZ’s Checkpoint programme (22 April 2016) that peer reviews of the report had been produced. The peer review(s) could usefully have been attached to the report; failing that, the report’s author should have explained their absence.

South Dunedin Action Group: Notes of meeting with DCC (3 May 2016)

Received.
Friday, 6 May 2016 6:02 p.m.

From: Clare Curran [Dunedin South MP]
Subject: Notes from the Meeting with DCC on 3 May
Date: Fri, 6 May 2016 00:31:05 +0000
To:

Dear everyone
Further to my last email here is the notes taken by office from the meeting with the Mayor and senior Council management on 3 May.
This is to keep you informed and for transparency purposes.

A new meeting date will be set up soon and I will keep you all informed

Kind regards

Clare Curran

[begins]

Notes from meeting 3 May 2016
South Dunedin Action Group (SDAG) and mayor + senior management

Mayor Cull
– acknowledged that there was collective concern, that they were pleased to meet with the group and that the meeting provided the best place to provide clarifications
– Acknowledged that the process had been lengthy and frustrating, and “sloppy”
– Council was now very sceptical about evidence relating to the flood and had been let down. He added that they would not make any changes to anything without evidence.
– If the event occurred again even with the proper maintenance there would have been severe flooding
– Determined to make the system we have work the best that it can
– Agreed need another mechanism other than the ODT to communicate with the community
– Will consider the discussion and come back with a proposal for the next meeting with a smaller group

Laura McElhone. Group Manager Water and Waste
– All mudtanks had been cleaned in South Dunedin (marked with green spray)
– Screen has been redesigned at pumping station, work about to go to tender, installation expected July/August
– Screen currently cleaned weekly by contract with photograph for proof
– Proposed screen modifications would see a 4 part screen to allow for safer and easier cleaning – could not confirm bar spacing
– Approx. 100 manholes had been lifted (Oct/Nov 2015) to identify any siltation – none identified as a problem – map can be provided of manholes checked – this exercise will be repeated in Oct/Nov 2016
– Confirmed that with the work carried out or in progress expected reduction in level of water would be about 200mm – however difficult to predict because too many variable to undertake modelling
– On issue of foul sewage infiltration confirmed that work being undertaken in Kaikorai Valley was to reduce the pressure on the system before it came through to Caversham
– On the issue of diverting foul sewage to Green Island treatment works stated that it was only able to handle a certain amount as it had been set up for a different type of sewage
– With regard to pumping out to sea, confirmed that they now know who to contact at the ORC and will maintain valves to enable this to happen if necessary
– Advised Musselburgh pumping capacity cannot run at maximum [this is disputed by Darrel]
– Forecast received on 2 June was for 1/3 less rain – only after midday on 3 June did they receive prediction on the size of the event
– Definitely had contractors and staff monitoring and out in South Dunedin, but did not have enough people to cover the scale of event
– Door-knocking by DCC did not record the number of flooded houses [DCC has not been back to check]
– 1968 flood had two peaks so had time to recover [disputed by Darrel]
– Too many variables to accurately measure topographical data
– Understand need to reassure and quantify but have to be careful not to give false impression
– Advised that 4/5 engineers employed in planning and 6/7 at the delivery end – acknowledged the identified lack of a storm water specialist – currently under recruitment

Ruth Stokes. Infrastructure and Networks General Manager
– Contractors have been asked to verify status of periphery areas
– Need to build resilience in the community – have recognised need to contact secondary schools and community groups and extend beyond the ‘What’s the plan Stan” initiative

Sue Bidrose. Chief Executive
– Unable to provide a figure on the number of roads closed by DCC as the water washed the cones away.
– Civil defence, Fire and Police all advised DCC that only 20-30 houses had been flooded – suggested that volunteers sandbagging were not part of the information loop and therefore message did not get through to emergency services

Kate Wilson. Councillor
– Have been advocating for a rain radar for a number of years on the Taieri

David B-P. Councillor
– Not just South Dunedin affected but other areas also, we need answers to give the community reassurance that the system is operating
