Clifton to Tangoio Coastal Hazards Strategy Joint Committee

Monday 02 May 2016

Subject: Confirmation of Stage One of the Clifton to Tangoio Coastal Hazards Strategy 2120

Reason for Report

1. This report seeks a resolution from the Joint Committee to adopt as final the two reports prepared by Tonkin & Taylor, and in doing so confirm the outcome of Stage One of the Clifton to Tangoio Coastal Hazards Strategy 2120.

Discussion

2. Stage One of the strategy is to ‘define the problem’ of coastal hazards between Clifton and Tangoio. This has been done through the work of Tonkin & Taylor and is presented in two reports:

2.1. Clifton to Tangoio Coastal Hazards Strategy 2120: Coastal Hazard Assessment. Tonkin & Taylor, May 2016

2.2. Clifton to Tangoio Coastal Hazards Strategy 2120: Coastal Risk Assessment. Tonkin & Taylor, May 2016

3. The findings of these reports have previously been workshopped with the Joint Committee.

4. At the last meeting of the Joint Committee on 10 March, 2016 both reports were adopted as drafts for consultation with stakeholders.

5. On 31 March a session was held with the Westshore Residents and Development Association (“WRDA”) and Walk on Water Limited (“WOW”). Separate meetings have also been held with the Port of Napier and Lifelines, and are ongoing with marae within the strategy area.

6. As a result of these sessions, formal feedback has been received from:

6.1. Westshore Residents and Development Association – Chairman Richard Karn

6.2. Westshore Residents and Development Association – Treasurer Dorothy Pilkington

6.3. Larry Dallimore

7. These submissions, and responses to them prepared by TAG, are provided as attachments to this report. Richard Karn and Larry Dallimore will also speak to the Joint Committee in support of their submissions.

8. A number of changes to the reports have been made in response to these submissions, principally to assist with readability. These are highlighted in the responses.

9. It is also noted that TAG have requested an amendment to remove a ‘max’ line from the coastal erosion assessment. This line represents a probability of less than 1% likelihood of occurrence and has been included to show the full range of modelled outcomes including those at the extremely unlikely end of the spectrum. Given that it is extremely unlikely for this land to actually be affected, it is not useful for any realistic planning response. TAG have requested the consultant utilise the 1% probability as the maximum extent used for hazards mapping and LIM notification.

10. It is also noted for completeness that TAG have accepted a recommendation from Tonkin & Taylor that we should not assume the sea exclusion wall at East Clive is maintained beyond the point at which coastal erosion is modelled to overcome it. This means that at 2120, coastal inundation is modelled to affect a large area of Clive which is previously (i.e. at present day and 2065) unaffected. While it is likely that a sea exclusion bank will continue to protect this area beyond 2120, it may be in a new location (i.e. inland) and TAG felt it prudent not to prejudge an outcome from Stage 3 and assume this decision (and its financial implications) as a given.

11. Should the Joint Committee accept the recommendation and adopt the two Tonkin & Taylor reports as final, this information will be formalised and ported to the Hawke's Bay Hazard Information Portal. It will also mean that any Land Information Memorandum (“LIM”) requested for a property within an area identified in the reports will include notation confirming the reports and their findings as information held by Council.

12. Given the size of the two reports, a link will be circulated to Joint Committee members ahead of the meeting to enable them to download electronic versions.

Recommendations:

1. That the Clifton to Tangoio Coastal Hazards Strategy Joint Committee confirm the following Tonkin & Taylor reports forming Stage One of the Strategy as final:

1.1. Clifton to Tangoio Coastal Hazards Strategy 2120: Coastal Hazard Assessment. Tonkin & Taylor, May 2016

1.2. Clifton to Tangoio Coastal Hazards Strategy 2120: Coastal Risk Assessment. Tonkin & Taylor, May 2016.

Clifton to Tangoio Coastal Hazards Strategy Joint Committee

Monday 02 May 2016

Subject: Adoption of Cell Extent for Stage Two and Stage Three

Reason for Report

1. This report seeks a resolution from the Joint Committee to adopt cell extents for Stage Three of the Strategy.

Discussion

2. Joint Committee members will recall that TAG were instructed to report back on recommended cell extents for cell planning purposes in Stage Three of the Strategy.

3. In developing a response, it became clear that the Joint Committee should make an early determination on this issue, given its implications for the design of the decision making process (and funding model) being developed in Stage Two.

4. To that end, TAG sought advice from Stephen Daysh from EMS, as the developer of the Stage Two decision making process, on options for dividing the strategy area into logical cells, and a recommendation on a preferred number and location of cells.

5. His recommendations have been workshopped with TAG, and are provided in the attached letter dated 26 April, 2016.

6. Mr Daysh will be present at the meeting to talk to his recommendations and answer any questions from Committee members.

Recommendation:

1. That the Clifton to Tangoio Coastal Hazards Strategy Joint Committee adopt the recommended Option V (North / South) as detailed in the letter from Mr Stephen Daysh dated 26 April 2016.
