Regional state of emergency lifted in Otago (incl Dunedin & Waitaki)

Otago’s state of emergency has been lifted.
Emergency Management Otago this morning lifted the state of emergency which existed since deluges and heavy wind battered Otago’s eastern coast over the weekend. The region has now officially entered a recovery phase with teams moving on to assessing the damage and checking on the needs of those affected by the devastating floods. Emergency Management Otago group controller Chris Hawker, in Dunedin, said the move towards recovery did not signal any reduction in effort.

Dunedin July Severe Weather update
10.45am Monday 24 July 2017

State of Emergency lifted

The Dunedin State of Emergency was lifted at 9am today. Under the Civil Defence Emergency Act 2002 we are now operating under a Notice of Local Transition Period as we move into the recovery phase.
The transition period is in force for 28 days (expires 9am 21 August) unless extended or ended earlier. The notice still gives the local authority powers to carry out essential emergency-related work.
More information about the work happening as part of the recovery phase will be provided today. The work will be led by Dunedin City Council Recovery Manager Simon Pickford.

Storm hits: what you need to know

Oamaru
Oamaru and surrounds are bearing the brunt of the storm, with widespread surface flooding and some homes flooded.

Mosgiel
There is surface flooding in Mosgiel, which is being closely monitored.

Sandbags
Mosgiel people concerned about rising water can access sandbags and sand from the Memorial Park car park beside the stadium/Mosgiel Memorial Gymnasium.
Sandbags are also available in South Dunedin at the car park behind St Clair Tennis Club, Victoria Road.
Where possible, people should bring a shovel to fill the bags, although contractors are available on-site at both locations to assist with filling and loading.

Information centres
As a precaution the council has opened information centres in South Dunedin, in The Mercy Room, Catholic Social Services, 42 Macandrew Rd, and at Mosgiel Fire Station Theatre, 3 Cargill St.

Freedom Campers
Due to the weather the Dunedin City Council recommends all freedom campers find alternative accommodation rather than staying at either of the council’s two freedom camping sites tonight.

Roads
NZ Transport Agency has issued road warnings for surface water and flooding across Otago, including SH1 from Waipahi to Waitaki Bridge.
Warnings are also in place for SH88 from Dunedin to Port Chalmers, SH 87 from Kyeburn to Outram.
SH83 from Pukeuri to Duntroon is also affected by flooding and is closed between Gray Rd And Horse Gully Rd.
In Canterbury SH 82 Waimate To Kurow is closed.
SH1 is now closed between Pukeuri to Morven

Rivers
The Kakanui, Shag and Taieri Rivers, the Silver Stream, Water of Leith and the Lindsay Creek are all rising steadily.

Flights cancelled
Flights to and from Dunedin Airport have been cancelled this afternoon.
The cancelled flights include Air New Zealand flights to and from Auckland and Christchurch.
The Jetstar flight from Dunedin to Auckland at 4.15pm has been cancelled.
Air New Zealand is advising customers booked to travel to and from Dunedin to consult the arrivals and departures information on our website here for up to date schedule information.

Sports grounds
The Dunedin City Council has closed all sports grounds for the weekend because of the weather.
The club rugby semi-finals may still go ahead at Hancock Park on Saturday depending on the weather. The decision will be made by the Otago Rugby Football Union.

Power cuts
There are reports of power cuts in Oamaru. In Dunedin power has been cut to about 100 customers in Green Island, Fairfield and Abbotsford suburbs of Dunedin after a power line came down.
Aurora Energy says it has a response crew working to fix the fault and power was expected to be restored by 5pm.

General preparedness
The Dunedin City Council is encouraging all residents and businesses across the city to make their own preparations.
Residents in low-lying areas who feel concerned should make plans to self-evacuate themselves to stay with friends or family who live on higher ground should it be required later on.
Check on neighbours, particularly if they are vulnerable.
Check spoutings and drainage channels for blockages and clear them if necessary
If your basement is prone to flooding lift items that could be damaged by water off the floor. Be sure garden sprays and other chemicals won’t be affected
Check grates near your house for blockages and keep them clear of leaves and other debris to avoid water building up and affecting your property.

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

Chairman of the Otago chapter of the Property Council New Zealand Geoff Thomas says policymakers need to be careful not to damage property development opportunities in South Dunedin.

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.

2GP PRESENTATION NOTES: LANDSLIDES
Neil Johnstone

I have no property interest in any landslide hazard area (although I did previously), nor in the Water of Leith catchment, nor in South Dunedin. My main purpose in appearing at this stage is to bring to the panel’s attention that the expert (so-called) opinions received from Otago Regional Council’s (ORC) natural hazard analysts are often deficient to the detriment of the 2GP process and the city’s residents.

I am a long-term resident of Dunedin and am highly experienced in flood control issues and solutions. I am appearing here on my own behalf, therefore not strictly as an Expert Witness in this instance, although I have done so in past years both in both the High Court and the Environment Court. I also acted as lead technical advisor to the NZ Govt investigation into the massive 1999 Clutha flood. My detailed investigations have ranged from simple issues such as the Water of Leith (as Investigations Engineer at Otago Catchment Board and ORC) to the entire Clutha catchment (in varying roles). These investigations have often incorporated the construction and operation of accurate, properly verified models.

I am now semi-retired MIPENZ, but still running my own consultancy on a reduced basis. I am a highly experienced expert in flood issues, I am much less so wrt landslide identification and mitigation (but I know a nonsensical report when I read one). ORC hazard analysts responsible for the landslide buffer zones originally imposed across my former property (and many others) need to accept that their approach was seriously flawed, and far from expert. Paul Freeland has mentioned to me in a recent phone conversation that Dunedin City Council (DCC) should be able to have confidence that ORC hazard analysts are expert. I have no strong criticism of Mr Freeland, but those days have passed – in this region at least – when expertise was based on proven performance, and not on a position’s title. A property previously owned by my wife and me in Porterfield Street, Macandrew Bay was quite ridiculously misrepresented in ORC’s landslide report of September 2015. The landslide hazard zone on that property has apparently now been removed, but uncaring damage has been done to us, and no doubt to many others. The Hazard 2 zone was reportedly imposed without site inspection, or without anybody properly reviewing output or checking accuracy of references.

[Reason for submitting: Natural Hazards section of 2GP dominated (undermined) by ORC hazards staff input and DCC failure to verify/review; DCC presumption that ORC “experts” do/should have appropriate expertise. We appear to be witnessing a proliferation of Hazard Analysts in NZ Local Government with little relevant experience or skill.]

2GP PRESENTATION NOTES: SOUTH DUNEDIN
Neil Johnstone

The comments re South Dunedin flood hazard contained in my original written submission were written prior to DCC’s producing its inaccurate flood reports in respect of the South Dunedin flooding of early June 2015 in which high groundwater levels were held to blame. These DCC reports were eventually released in late November 2015 and April 2016 respectively. My analyses (well after my original submission) demonstrated that the prime cause of widespread flooding in South Dunedin was DCC’s failure (in order of probable significance) to utilise the bypass facility at Tahuna Wastewater Treatment Plant, to fully utilise its stormwater pumping capacity at Portobello Road, and to maintain its stormwater infrastructure (mudtanks etc). Inflow of “foreign” water from the St Clair catchment added to the depth of inundation in some areas. All these can be remedied by a diligent Council. Some have already been remedied, as positively demonstrated in the admittedly rather over-hyped rain event of the subtropical cyclone remnant around this past Easter.

ORC natural hazard analysts were probably responsible for the origin of the groundwater myth as a cause of the South Dunedin flooding in their Coastal Otago Flood Event 3 June 2015 report. Reference was made there to “elevated” ground water levels. They followed up with a contentious report (The Natural Hazards of South Dunedin, July 2016). This opens by stating that the June 2015 flooding was caused by heavy rainfall and high groundwater levels, with no mention of mudtanks, or pumping failures (plural). Such reporting cannot be treated as balanced, nor its authors credible. Elsewhere, ORC essentially conceded the groundwater myth in Rebecca Macfie’s excellent NZ Listener article entitled Flood Fiasco (June 11, 2016).

Shortly after, however, ORC produced the aforementioned South Dunedin Hazards report (backed up by an embarrassingly inaccurate video presentation) that seems to reflect a desire to preach doom rather than convey a balanced defendable scientific analysis of South Dunedin realities and solutions where needed.

One of the worst features of the report and subsequent video was the depiction of projected permanently inundated areas of South Dunedin based on ORC modelling of rising sea level effects. These depictions made front page news in the Otago Daily Times with flow-on reporting nationally. The mapped areas of inundation are actually taken from an earlier ORC report entitled The South Dunedin Coastal Aquifer and Effect of Sea Level Fluctuations (October 2012). The modelling was based on limited information, and the findings would therefore be expected to be of limited reliability. The 2012 report essentially confirms this, noting that modelling of existing conditions overestimates actual groundwater levels (by the order of half a metre in places). Figure 2 (Scenario 0) of that report shows significant permanent ponding for current conditions. None exists in reality. Almost lost (in Section 3.8) are the following (abbreviated, and amongst other) concessions:

• Uncertainty of input data
• Potential inaccuracy of model predictions
• High level of uncertainty
• Groundwater system is poorly to moderately well characterised
• Aquifer properties are poorly understood or quantified
• Each of these uncertainties could have the effect of overestimating the groundwater ponding in the current setting.

The reader is advised to read the full Section 3.8 to ensure contextual accuracy. In my view (as an experienced modeller), a study that cannot even replicate known existing relationships is imperfectly calibrated and unverified. It cannot therefore be relied on. Strictly speaking, it does not qualify as a model. The relationship between possible sea level rise and consequent groundwater impact remains highly uncertain.

Unfortunately, the 2016 ORC South Dunedin Hazards report (and video) chose to reproduce the 2012 ponding predictions using more recent data (but without any better appreciation of aquifer characteristics), but the predictions are similar. It is noted that no Scenario 0 mapping is included in the latter report, nor are the model’s inherent weaknesses described. No admission of the potential modelling inaccuracies is presented other than the following note in Section 4.1: “Further discussion of the original model parameters, model calibration and potential pitfalls is included in the ORC (2012a) report, which can be accessed on the ORC website”. I believe that all parties were entitled to know unequivocally that the modelling was unreliable and unverified.

The 2016 report also makes reference to the fact that dry-weather ground water levels at the Culling Park recorder are at or below mean sea level. This is attributed by the authors to leakage of ground water into the stormwater and wastewater sewers. If that is correct (I would reserve judgement as to whether there may be other factors), then we are witnessing just one example of how an engineered solution could be utilised to dissipate increasing depth of groundwater. Such solutions are canvassed in the BECA report commissioned by DCC several years back.

To summarise, South Dunedin’s exposure to flood (current or future) is poorly described by ORC hazard analysts. The 2GP process seems to have seen these analysts “adopted” by DCC planners as their experts. I consider that to be an inappropriate approach to the detriment of our citizens.

The proposal to require relocatable housing in South Dunedin seems premature, and based on highly questionable information. The proposal for relocatable housing in South Dunedin also rather pre-empts the currently-planned DCC study of overseas approaches to sea level rise solutions.

Requiring relocatable houses will likely simply mean that aged houses that should in time be replaced will be repaired instead. Who is going to build a new relocatable house if they have nowhere to relocate to and probably insufficient money to acquire the requisite land? The proposal to require relocatable housing is ill-considered and premature in my opinion.

With respect to ground water issues across South Dunedin, the 2016 Hazard Report presents –

The reason for my pointing out these facts is to encourage Commissioners to take a step back from the current hysteria surrounding South Dunedin. Had the 2015 flooding extent been restricted (as it should have been) to that which occurred in a slightly larger rainfall event in March 1968, the event would have already been forgotten. Seemingly, at least partly as a result of that hysteria, the proposal to require relocatable housing in South Dunedin seems premature, and based on highly questionable information. Just as ORC floodplain mapping contradicts its in-place flood protection philosophy, so does the proposal for relocatable housing in South Dunedin also rather pre-empt the currently planned DCC study of overseas approaches to sea level rise.

Requiring relocatable houses will simply mean that aged houses that should in time be replaced will be repaired instead. Who is going to build a new relocatable house if they have nowhere to relocate to and probably no money to acquire the requisite land? The proposal for relocatable housing is ill-considered and premature in my opinion.

2GP PRESENTATION: URBAN STREAM HAZARDS
Neil Johnstone

Urban Stream Comment re Leith and Lindsay Streams:

ORC’s mapping is said to be of residual flooding (post-flood protection works of the past 80-plus years), but actually represents what might have been envisaged many decades back in something considerably greater than the record 1929 flood with none of the very significant channel works of the 1930s, 1940s and 1960s; or even those lesser improvement of the 2010s in place. The ORC 2GP mapping includes areas that didn’t get flooded in 1923 or 1929. I agree with some potential dangers of stream blockage (especially in Lindsay Creek, and to a lesser extent at Clyde Street and Rockside Road), but one can only consider locations of feasible blockage in today’s conditions. Furthermore, accepted professional practice for flood plain mapping requires detailed hydrology, probability analyses, climate change allowance, hydrograph routing, in-channel modelling (allowing for stream capacity variability), and overland flow modelling. ORC’s flood mapping incorporates none of these fundamentals; instead, it reads as little more than a colouring-in exercise, when a professionally researched technical document is required. In short, ORC’s hazard analysts have carried out no fit-for-purpose analysis for a District Plan process.

Interestingly, the concerns expressed by ORC hazard analysts re channel blockage are entirely inconsistent with ORC’s own design philosophy and consent application evidence for the recent Flood protection scheme (so called). Design Philosophy minimises the issue.

Very briefly, the mapping is challenged for the following reasons (inter alia):

No descriptions of the effective flood protection initiatives (OHB -1920s and 1930s, DCC -1940s, OCB -1960s) are included. These works have ensured that overtopping is practically impossible in the George Street to Cumberland Street reach, the Clock Tower reach and Forth Street to Harbour reaches. Flood protection in these areas are all built to a much higher hydraulic standard than the so-called ORC scheme of the past decade, and to a far, far higher standard than existed pre-1929.

It is further noted that ORC’s own Design Philosophy Report (OPUS for ORC, 2005) for the proposed Leith/Lindsay flood protection scheme is adamant that debris traps recently (then) constructed at Malvern Street and Bethunes Gully would further mitigate any debris problems. Refer paras 7.7 and 10.6 of that document.

Ponding is mapped where water couldn’t even reach in 1929 (peak flood currently estimated at 220 cumecs, and predating flood protection measures) in the wider CBD area. Flows along George Street in the 1920s only occurred south as far as about Howe Street, then re-entered the river. Nowadays, the accelerating weir above George Street and the structural high velocity channel immediately downstream provide much more clearance than existed in 1929. [Most outflow then from the river occurred much further downstream.] In those downstream reaches, many of the bridges have been replaced or upgraded. Possible remaining points of interest are the hydraulically insignificant extension (circa 2015) of the St David Street footbridge, the historic Union Street arch footbridge, and the widened (circa 2012) Clyde Street road bridge. The flimsy St David Street bridge would not survive any hydraulic heading up so there would likely be of little flood consequence, and backing up upstream of Union St would be largely inconsequential because of the height of the Clock Tower reach banks immediately upstream. The Clyde Street bridge is acknowledged as being lower than optimum, but it has not created any issues in its half century existence. Any overtopping there could only impact on a limited area between the bridge and the railway line.

Overland lows beyond (east of) the rail line remain highly improbable because of the ongoing blocking effect of road and rail embankments. Flows as far as the railway station to the west of the rail line are also highly improbable nowadays as only the Clyde Street area could conceivably contribute.

The 1923 photograph showing ponding along Harrow Street is presented by ORC with an unfortunate caption stating that the water is sourced from the Leith. Some undoubtedly was, but the whole of the city was subject to “internal” stormwater flooding from Caversham tunnel, across South Dunedin to the CBD and beyond. To illustrate further, a NIWA April 1923 flood summary (accessible online) provides a summary of some of the information more fully described in technical reports and newspaper accounts, including:

• Portions of Caversham, South Dunedin, St Kilda, the lower portions of central and northern areas of the City and North East Valley were completely inundated.
• Water in South Dunedin was waist deep.
• The Water of Leith rose considerably and burst its banks in many places, causing extensive damage along its banks and flooding low-lying areas.

Today’s stormwater infrastructure is rather more extensive and effective (when maintained), and DCC has a continuing legal obligation to provide to maintain that service.

The levels plotted across Lindsay Creek seem highly pessimistic. Levels are shown to be of the order of 2 metres above North Road in some locations at least. I have [no] knowledge of any such levels ever having been approached. Care must be taken not to include unfloodable areas in the mapping. I don’t however discount localised channel blockage, and the channel capacity is substandard in many areas. The valley slope ensures that overland flow will achieve damaging velocities. Such velocities are noted in the NIWA summary.

Of greater concern to me, however, is that ORC’s mapping appears to have seriously underestimated the significance of potential Woodhaugh flood issues:-

The river channel through here is both steep and confined. The influences of Pine Hill Creek (immediately upstream) and Ross Creek (immediately downstream) add to turbulence and bank attack. The area was ravaged in 1923 and 1929, and there have been evacuations in some much lesser events in later decades. These areas are at considerable risk in a 50- to 100-year plus event. Hardin Street, Malvern Street had houses evacuated in the 1960s flood. High velocity, rock laden flows and mudslides can all be anticipated, and difficult to counter. Area below camping ground / Woodhaugh was overwhelmed in floods of the 1920s – a focus for flooding depth and velocity.

If the 2GP process is to include urban flood maps, these should be diligently derived, based on historical record and appropriate modelling. The mapping should reflect the real flood risks (including likelihood, velocity and depth). The decreasing flood risk from Woodhaugh (potentially high impact) through North East Valley (moderate impact) through to the main urban area south of the Leith waterway (localised and of little-to-zero impact) should be reflected in the mapping.

DCC leases space for South Dunedin community hub at Cargill Enterprises

How many years has this taken DCC
It’s still only “temporary” accommodation….

South Dunedin has been waiting for a public library since the time of borough amalgamation.

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.”
