almost 4 years ago
CLOSED: This discussion has concluded.

Examples include Council assets (e.g. roads, reserves), community assets (e.g. surf clubs), cultural heritage sites (e.g. marae, historic sites) or private property.

You can be generic or mention specific examples.

UPDATE 12 SEPTEMBER 2017: Adoption of the Policy:

Council has adopted a Coastal Erosion Responses Policy to enable consistent decision-making where Council-owned coastal land is affected by coastal erosion or subsidence.

    Tanners Point has some serious erosion issues.I have just spent 20 minutes writing them up, but everything seems to have vanished into cyber space!I am the first to admit I am not good with computers.Work and mapping and a survey needs to be undertaken around Tanners Pt.We have several hot spots and two areas that need work immediately, the end of Moana Drive needs to be addressed urgently before all of the reserve disappears and the road and private property will be endangered after that. Over the last 13 years we have lost up to 10 metres off the crest...the slope below varies between 45 & 90 degrees.The other area is below No 13 Giles Way, where there have been several slips, the latest, in 2012 and no remedial or tidy up work has been undertaken by Council, the residents re-created the walkway track which vanished down the hill. Drainage and piping needs t be done, as this is a natural bowl and water flow area. The adjoining resident has piped his storm water into the Council system, which will help reduce waterflow overland.

    Omokoroa peninsula has been designated an urban growth node for the wider region. I understand this is a decision made by all 3 councils : WBOPDC, Tauranga City and EBOP the regional council. Designated urban growth nodes allow the population to grow, and infrastructure to be developed, while avoiding the unplanned spread of housing and sections into the surrounding productive hinterland.For this reason I believe it is important that Omokoroa receives the proper investment from the wider regional rating base, to allow the infrastructure in the peninsula to reflect the needs of the local population but also the growth needs of the wider region.Coastal erosion is a problem in many areas of Tauranga harbour. The soil is basically a volcanic ash pile that falls into the harbour unless properly retained. There are serious visible slips at Omokoroa, Pahoia, Maungatapu and other locations. However, the slips at Omokoroa are the worst and are the closest to high density housing.While sea level rise is definitely a concern, I believe it is too great an issue to consult on meaningfully. Whole cities will have to shift if some of the projections are accurate. Hence the current focus should be on more tangible and immediate issues such as existing coastal erosion trends.My own property is not affected by slips, but I believe the whole community shares the risk that slips will degrade our living environment unless substantial remedial investment is made.At present we have slips at Omokoroa that are very serious (eg top of Bramley Drive and main walkway along the clifftop), that are a massive eyesore and potentially dangerous. These slips are a very bad look for a proposed urban growth area.While I accept that not much can be done to remediate the slips, I do note that Council has completed a substantial amount of work in rockwalls below certain parts of the cliff edge.My belief is that the rockwalling is a visually attractive compromise between the costs of stabilising the cliffs and the need to keep a shoreline that is protected from further erosion.Hence my suggestion is that the rockwall concept be extended considerably, as follows :• Build a rock-based walkway (ie promenade, 3-4 m wide) right around the tip of the peninsula (approx from Waterview Terrace to the Domain). Build in stages over a 10 year timeframe.• The walkway could eventually replace the disjointed and street-bound elements of the current walkway, allowing a complete circuit of the peninsula for pedestrians, without having to navigate from one section to another through residential streets. It would also avoid the issue of having to maintain the clifftop path in those places where erosion will inevitably prevent access at some future point.• Where the walkway is below an erosion-prone cliff, it should be built some 5-10m on the seaward side of the high tide mark, with culverts to allow the tide through. This would keep the walkway clear of any future debris from slips; in fact, debris falling would effectively back-fill the shoreline and could be planted out accordingly.• The cost should be met by the region-wide rating base because of the Smart Growth plan for Omokoroa. Sections of the walkway might be sponsored by local businesses etc to assist in funding.

    Private property should be protected. Property owners acquired property on the basis of collective community decisions made by elected representatives. They should not now be penalised by an attempt by the communities to wash their hands of those collective decisions.

    Managed retreat, some properties at Waihi Beach along Shaw Rd have done this years ago. Others should follow suit. It was their decision to buy beachfront. Sand sausages, removal of the rocks & dune care planting & protection.
  • snapper about 4 years ago
    When the issue of Coastal Erosion first came up leading to the last Environment Court hearing regarding the Waihi Beach Seawall the community of Waihi Beach were asked to name their most favoured option...it was managed retreat...which meant that buildings would have to move back if the erosion threatened the properties. However the Council and the Environment Court decided otherwise and it is very noticeable that therehas been a general upgrade in the quality, size and value of beachfront dwellings because of the seawall. This should not mean that the residences are more important than any other part of our beachfront or that they should be prioritised. They are important but no more important than roading, car parks, and various items of infrastructure or the beach itself. I mention the last because it is the beach that suffers from attempts at coastal armouring or inappropriate development, and if anything should be prioritised it is the beach itself.

    Stop taking the sand from the streams that feed to the coast. If the sand is taken out of the streams then it should be put back on the beach!

    You shouldn't be thinking about exceptions. The over-arching approach should be recognising that King Canute's power is a myth. Restoring coastlines is priority, not protecting ''ässets". Working with nature is the only sustainable and least expensive option.

      You are dead right.

    Harbour tidal flows have over the years have been. altered. dramatically by the Port of Tauranga dredging ..to extend .the wharfs and dredging the main entrance at Mt Maunganui.We at the northern end have seen the tide movement .change to the extent that the flow on the out going tide seems to move more towards the Tauranga end where years ago the tidal flow was seen to be at Matahui when the flow went both ways...The Bowentown entrance is now silting up and causing the waves to build up closer to the shore which has caused erosion on Matakana and along waihi beach So our problem is man made to acertain extent and a fluid dynamics engineer would show what the .water pressure is doing to the harbour and the entrances .So funding could come from the Port of Tauranga

    I feel that soil needs to be stopped from polluting our harbour from all sources. Cooney Reserve and the slip on Bramley Drive, Omokoroa constantly have soil washing into our harbour. After the fire in Cooney reserve in 2012 where the soil was left bare the erosion has reduced the reserve by many metres. I would like to see gabian cages put where soil is exposed and re-sanding to further protect our shore. Environment BOP gets farmers to fence all waterways but leaves their own waterway to erode and pollute. I would like to see any slips (is Bramley Drive) have a bund applied asap to contain the soil then cleaned up and rocks or gabion cage applied to stabilise the area.

    I live in Preston Drive, Katikati where we have a huge mangrove problem. I am told these bushes were not here 20 years ago. It appears to me that because of these the water from the harbour is being forced ever closer to the houses and footpath, breaking down the "river" banks. Mangroves collect silt, silt builds up, forces the water channels to cut more and more the the soil awayfrom the banks. I feel that either the mangroves should be removed and/or concrete blocks to be installed along the banks to stop further erosion. After each large rain event more bank falls away. When will it stop?

    The entire shoreline should be a priority, with an overarching programme of ecological restoration rolled out and implemented. This is not a problem that can be solved with an ad-hoc, piece-meal approach, the whole shoreline must be viewed in its entirety and a consistent and pragmatic approach undertaken.
  • john Beveridge about 4 years ago
    I live at Plummers Point and the erosion on both sides of the peninsular has been substantia In the last 10 years and most could be stopped with not huge amounts of money being spent. I would like to have some input on a face to face basis if possible some time in the future [ on site.]John.
