Our levels of service and how we measure progress against them Levels of Service

We will know we are meeting the Level of Service if...

Current Performance

We maintain Council’s stopbank assets in River X classified areas to deliver flood

protection to the level that the stopbanks were originally constructed.

The major flood protection and control works that are maintained, repaired and renewed to the key standards defined below

(Mandatory Performance Measure 1):

Our stopbanks are maintained to their original constructed standard.

(Riwaka River = 1 in 10 year flood return in 1950).

(Lower Motueka River = 1 in 50 year flood return in 1950).

(Waimea River = 1 in 50 year flood return in 1950).

No failure of flood protection in the existing stopbank system

maintained by Council below the specified design levels.

[Target:

Riwaka River 88%

Motueka River 100%

Waimea River 100%]

We have had two significant floods affecting two of our flood protection schemes in the last financial year.

In February 2016 the Waimea River reached flood levels. This was a 5% AEP* (1:20 year average return period) event. The event was fully contained within the stopbanks, with river flows reaching the top of the stopbank in the lower part of the Waimea River just above Appleby Bridge. At the river mouth, the peak of the flood occurred close to low tide, with flood waters reaching only 1/3 of the way up the lower river stopbanks.

The Waimea River scheme is designed for a 2% AEP (1:50 year event) plus 0.6m of freeboard. This event was therefore well within the design capability and the stopbanks performed as anticipated.

On 26 March 2016 the Riwaka flood occurred.

This was approximately a 1:30 year flood event, which was over and above our design standard for the Riwaka River stopbank system. Despite this, the stopbanks below State Highway 60 bridge held the flood waters within its banks with limited overtopping. Due to the size of the flood event, the river did burst its banks, but above the sections with stopbanks. The Council investigated options for extending the stopbanks in 2007 but did not proceed with an extension. Currently, staff are assessing the riverbed to determine if gravel needs to be extracted to restore channel capacity.

With no floods associated with the Motueka River, the following targets for these flood protection schemes were therefore met:Riwaka River: 100%

Motueka River: 100%

Waimea River: 100%

*Annual Exceedance Probability River maintenance

tasks are carried out in a safe, efficient and sustainable manner.

Council holds appropriate consents for the work it does.

As measured by the number of notices issued to Council’s flood protection and rivers control activity.

[Target: no notices issued]

We have applied for a new Global Rivers consent to cover river maintenance works and expect the resource consent to be finalised in 2016.

We continue to work under consent NN010108 until such time as the Global Rivers consent is granted.

No notices were issued or we also had no issues investigated.

Levels of Service (We provide)

We will know we are meeting the Level of Service if...

Current Performance

We manage

waste/rubbish in the river system.

Complaints about illegal dumping in the X and Y classified rivers and on adjacent beaches on public land are actioned within five days.

As measured through Customer Service Requests in Council’s database. CSR’s are responded to within five days.

[Target: 100%]

We can report that 100% of complaints were responded to within the five-day target period.

This result excludes complaints relating to abandoned vehicles, as these are managed by our Regulatory and Compliance group.

Figure 38. Comparison of number of performance measures met over three years

The Flood Protection and River Control Group have met all the performance targets set in the Long Term Plan 2015-2025.

The performance measures are similar to those contained in the last Long Term Plan, although we no longer report on two measures, relating to the removal of ‘crack willow’ and progress on an Annual Operating Maintenance Programme for the River Y catchment as we have moved to a reactive maintenance programme instead.

Major Activities

This group of activities includes ongoing management, maintenance and renewal of Council’s flood protection and river control assets, including promoting soil conservation and mitigating damage caused by floods.

There are no major capital works programmed for Years 1-3 of the Long Term Plan 2015-2025.

Comment:

Capital expenditure

The programme of work was not completed as expected. We anticipate a significant amount of the underspend will be carried over to 2016/2017.

Reserve movements increase or decrease

The movement in reserve is a reflection of the underspend in this activity. The amount of surplus in this activity has increased.
