The Northland Regional Council (‘NRC’) applies for the resource consents described below: Far North District Plan x Land use consent - Rule 12.3.6.3 ‘Excavation and filling’ – Discretionary activity. - Rule 7.6.5.3.8 ‘Noise’ – Restricted discretionary activity. - Rule 8.6.5.3.5 ‘Noise’ – Restricted discretionary activity. - Rule 7.8.5.3.4 ‘Noise’ – Restricted discretionary activity. - Rule 9.7.5.2.3 ‘Noise’ – Restricted discretionary activity. Operative Regional Water and Soil Plan (RWSP) x Land use consent - Rule 33.2.1 ‘Earthworks not located in the Riparian Management Zone – Controlled activity. - Rule 34.3.1 ‘Earthworks within the Riparian Management Zone’ – Discretionary activity. - Rule 27.3.1 ‘New stopbanks or modification to existing stopbanks’ – Discretionary activity. - Rule 29.4.1 ‘River bank protection works that do not comply with Rule 29.1(8)’ – Discretionary activity. - Rule 29.4.1 ‘Culvert crossings that do not meet the requirement of Rule 29.01.03’ – Discretionary activity. x Discharge permit - Rule 22.3.1 ‘Diversion and discharge of stormwater from a land disturbance activity’ – Discretionary activity. i Proposed Regional Plan (PRP) x Land use consent - Rule C.2.1.11 ‘Activities in the beds of lakes and rivers’ – Discretionary activity. - C.2.1.12 ‘New flood defence’ – Discretionary activity. - Rule C.3.1.8 ‘Obstructions that divert water onto other property’ – Discretionary activity. - Rule C.4.1.7 ‘Other land drainage and flood control activities’ – Discretionary activity. - Rule C.8.3.4 ‘Earthworks’ – Discretionary activity. 2. The activity to which the application relates (the proposed activity) is as follows: The proposal is to undertake various works associated with the upgrading of the Awanui Flood Scheme. The general objective for the upgrade is to: x To protect urban Kaitaia to a design standard equivalent to a 1:100 year ARI event with an allowance for climate change and freeboard; and x To improve safety of the riverbanks against slope failure. In undertaking the above works, the area will also see a decrease in the frequency of flooding for surrounding farms, which are currently protected against the 1:5 year ARI event. The works will see this protection improved to approximately a 1:20 year ARI event. The modelling plans attached in Appendix 9 demonstrate the positive flooding effects on the surrounding Kaitaia area. In order to achieve the above objectives, channel capacity is proposed to be increased via the implementation of three general methods: 1. Channel widening (benching). 2. Adding spillways within the flood channel. 3. Raising stopbanks. 4. Constructing floodwalls. 5. Toe stabilisation works. These works will be undertaken in general accordance with the NRC Scheme Design Plans attached in Appendix 3. 3. The names and addresses of the owners and occupier (other than the applicant) of the land to which the application relates are listed in Appendix 16. ii 4. The proposed activities will take place in various locations alongside the Awanui River and the Whangatane Spillway. 5. There are no other activities that form part of the proposal to which this application relates. 6. No additional resource consents and statutory approvals are needed for the proposal to which this application relates. 7. We attach an assessment of effects on the environment that: (a) includes the information required by clause 6 of Schedule 4 of the Resource Management Act 1991; and (b) addresses the matters specified in clause 7 of Schedule 4 of the Resource Management Act 1991; and (c) includes such detail as corresponds with the scale and significance of the effects that the activity may have on the environment. 8. We attach an assessment of the proposed activity against the matters set out in Part 2 of the Resource Management Act 1991. 9. We attach an assessment of the proposed activity against any relevant provisions of a document referred to in section 104(1)(b) of the Resource Management Act 1991, including information required by clause 2(2) of Schedule 4 of that Act. Included is a check list of relevant Schedule 4 matters. 10. No other information is required to be included in the district or regional plan(s) or regulations.
