​Kia ora Shane,

First off, thank you for coming to the town meeting and fronting up. I found your receptive nature in this issue enabled good flowing conversations albeit emotional.

Over the weekend, specifically Saturday we had rain fall somewhat heavily but for a short moment. According to Metservice, we had 6.8mm of water over about 40mins or so. Please see attached photos (July 9) which show that with 40 mins of rain at 6.8mm, the stormwater system on the Corner of Geisen and Awahuri Road was barely able to cope.

To demonstrate what I mean when I said the overflow falls down to us. If you open google maps, and start at the top of Ranfurly Road or Glasglow Terrace and make you way south it links to either Geisen (from Glasglow) or West Street. Geisen then intersects Awahuri Road and that's where the problem is. Please see attached video demonstrating the Dec 21 Flooding (please excuse the harsh language).

My key questions that I'd like answered either by you, the CEO of MDC, the mayor or a combo of all three are:
1. Since the original flooding in 2015, has there been any significant upgrades or improvements (not repairs) to the stormwater infrastructure on the corner of Awahuri Road and Giesen Road?
2. If it has not, can you please provide me a works list or record of any work done to the stormwater on Awahuri Road / Giesen over the last 10 years?
3. Since the original flooding in 2015, how many new houses have been approved by Council in the vicinity of Sandon Road and Ranfurly Road.
4. Since those approvals were granted, how many upgrades were done to the existing stormwater system (Awahuri/Giesen Road)?
5. The $18m supposedly put forward to the repairs to the stormwater, what is the plan for that? Are you upgrading old systems or creating dams etc?
6. Can I please be provided with a map that demonstrates the stormwater system flow pathway and if required, book a time with a MDC engineer to discuss it?
7. Finally, is there scope to have some sort of grey water truck and water pumps used to assist people in pumping water from their properties? For example, if we were able to divert some of the water from the intersection of Awahuri/Giesen and put some of it into Lancewood Lane this may stop the build up of water.
I acknowledge that given the filings against the MDC may restrict some of the answers you provide, if that is the case can you please highlight which question number you cannot answer and I will re-ask after the legal proceedings have ceased. 

If you would like more photos / Videos, I am happy to provide them to you. I have CC'd in Edmund O'Leary as he has yet to respond to any of my questions directed to him (approximately two weeks ago) and perhaps may get a response from him as well.
Response:

​I refer to your official information request dated 09 July 2022. The information you have requested is below.

1. Since the original flooding in 2015, has there been any significant upgrades or Improvements (not repairs) to the stormwater infrastructure on the corner of Awahuri Road and Giesen Road?
No significant upgrades to stormwater infrastructure on the corner of Awahuri Road and Giesen Road.

2. If it has not, can you please provide me a works list or record of any work done to the stormwater on Awahuri Road / Giesen over the last 10 years?
Nothing on stormwater – kerb and channel and sumps cleaned regularly as scheduled under the roads maintenance contract.

3. Since the original flooding in 2015, how many new houses have been approved by Council in the vicinity of Sandon Road and Ranfurly Road.
A per attached aerial up 7 houses have been constructed that may drain into the Glasgow Terrace pipework.

4. Since those approvals were granted, how many upgrades were done to the existing stormwater system (Awahuri/Giesen Road)?
None

5. The $18m supposedly put forward to the repairs to the stormwater, what is the plan for that? Are you upgrading old systems or creating dams etc?
A mixture of pipework and detention works has been planned, depending on the best option for each catchment.

6. Can I please be provided with a map that demonstrates the stormwater system flow pathway and if required, book a time with a MDC engineer to discuss it?
Final options for Giesen Road and Glasgow Terrace have not been determined. However, current thinking is a combination of detention and larger pipes to accommodate the 1% AEP flow form Glasgow to the Makino Stream.

7. Finally, is there scope to have some sort of grey water truck and water pumps used to assist people in pumping water from their properties? For example, if we were able to divert some of the water from the intersection of Awahuri/Giesen and put some of it into Lancewood Lane this may stop the build up of water.
We will consider this request, however we want to inspect the existing sumps and pipe joints at the Giesen/Awahuri intersections as some of these appear to be in a poor condition and easily blocked.

You have the right to seek an investigation and review by the Ombudsman of this decision. Information about how to make a complaint is available at www.ombudsman.parliament.nz or freephone 0800 802 602.
