22.214.171.124 Integrated Catchment Management Plan
||Where a full ICMP already applies to an area, development of Three Waters infrastructure shall be undertaken in accordance with it. This will be considered a means to achieve compliance with the standards in Rules 126.96.36.199(b) and 188.8.131.52 to 184.108.40.206.|
||In areas where an ICMP does not exist an ICMP as described in Volume 2, Appendix 220.127.116.11 shall be prepared for development or subdivision:|
||Creating more than 40 additional residential units on any site.|
||Creating more than 40 additional allotments.|
||Of any land involving more than 3ha.|
|||iv.||For development of Stage 1 of the Rotokauri Structure Plan beyond the area identified in Figure 25.13.4a). Preparation of this ICMP shall, where relevant to the particular catchment, take into account the entire area of Stage 1 of the Rotokauri Structure Plan, including the area identified in Figure 25.13.4a).|
|||Except that a separate ICMP is not required when all the information that it would otherwise include is incorporated into an approved Concept Development Consent for a Major Facility prepared under Rule 17.4 and the Concept Development Consent is accepted as satisfying the requirements of this rule.|
1. The 3ha trigger in Rule 18.104.22.168(b)iii) relates to the footprint of the proposed development or subdivision.
2. A full
ICMP should be prepared at the Structure Plan stage in accordance with Chapter
Figure 25.13.4a: Area of development within Rotokauri which is
excluded pursuant to
Rule 22.214.171.124 b) iv
||A stormwater reticulation and disposal system shall be provided that is adequate to safeguard people from injury or illness and protect property from damage caused by surface water.|
management measures shall be in place and operational upon the completion of
subdivision and/or development to ensure that the rate of stormwater discharge
offsite is at or below pre-development rates.
Stormwater management measures shall be implemented, as appropriate, in
accordance with the following drainage hierarchy: |
and gradual release to a watercourse|
1. Acceptable means of compliance for the provision, design and construction of stormwater infrastructure,
and the drainage hierarchy, are contained within the Hamilton City Infrastructure Technical Specifications.
2. Bylaws may also impose additional controls or restrictions with regard to stormwater.
Rule 25.2.4 regarding earthworks.
||An adequate, reliable, safe and efficient wastewater service shall be provided.|
||Where any subdivision or development results in additional allotments or buildings to be used for urban purposes, provision shall be made for a wastewater system as follows.|
||The installation or upgrading of the wastewater network and/or wastewater pump stations to serve all proposed allotments and/or buildings, and|
||Connection to the wastewater network from each proposed allotment or building.|
||In the Future Urban Zone and Large Lot Residential Zone (Ruakura Structure Plan area only) where network utility services for wastewater treatment and disposal are not provided by Council, each sites shall adequately provide for its own on-site treatment and disposal of wastewater and provide evidence of a satisfactory wastewater system to Council: no on-site wastewater treatment and disposal system shall be allowed that services more than one site and crosses any site boundary.|
||An adequate, reliable, safe and efficient supply of potable water shall be provided.|
||Where any subdivision or development results in additional allotments or buildings to be used for urban purposes, provision shall be made for:|
||Water metering infrastructure, and either|
||A connection from the public water supply reticulation to each proposed residential allotment or existing building, or|
||A public water supply reticulation system extending from the main trunk water supply system (or from an existing water supply reticulation if appropriate) to allow a service to be connected from the transport corridor frontage of each non-residential allotment.|
||In the Future Urban Zone and Large Lot Residential Zone (Ruakura Structure Plan area only) where a water supply reticulation system is not provided, evidence of satisfactory water supply shall be provided as part of the consent application.|
||A reticulation system shall be provided which is adequate for fire-fighting purposes and for estimated domestic and commercial consumption.|
||Where a development results in high-use allocation from the water supply reticulation system, evidence of satisfactory water supply shall be provided.|
126.96.36.199 Water Efficiency Measures
||In addition to Low Flow Fixtures, at least one water sensitive technique for stormwater shall be incorporated, connected to, achieved or maintained as part of any new development as identified below.|
i. New residential units
ii. Other new buildings containing a kitchen, laundry or bathroom
- Detention of stormwater to 80% of pre-development runoff by an appropriate means
- Permeable surfaces protected to achieve at least 20% above the minimum standard of the zone
- Rainwater tank for non-potable reuse system
- Other equivalent feature
1. An ICMP (relevant to the site) and the Hamilton City Infrastructure Technical Specifications can provide guidance on the above water sensitive techniques and other equivalent features.
maintains a register of all full ICMPs and can advise of any relevant to a
particular development proposal and site.
3. Where the site is covered by an ICMP, the water sensitive techniques required by 188.8.131.52(a) above shall be consistent with the recommendations of that Plan.
4. An ICMP may make recommendations identifying water sensitive techniques that are suitable (or unsuitable) for a particular catchment or specific Three Waters measures or targets that need to be achieved. In order for new development to comply with 184.108.40.206(a), the selection and implementation of water sensitive techniques must be consistent with any relevant recommendations.
5. To be effective rainwater tanks for new buildings should have a capacity of at least 5,000 litres or should be appropriately designed considering the specific site constraints.
6. Additional techniques are listed within the definition of "water-sensitive techniques" included in Section 1.1.2 of Volume 2 - Definitions Used in the District Plan.
||Rainwater tanks with a capacity of <10,500 litres are exempt from the following bulk and location provisions of the relevant zone.|
||Rear or side boundary setbacks.|
|c)||Low flow fixtures shall be incorporated in alterations or additions to any existing building that add an extra toilet, kitchen, laundry or bathroom. |
220.127.116.11 Water Impact Assessments
||A Water Impact Assessment, as described in Volume 2, Appendix 18.104.22.168, is required for any development or subdivision:|
||Creating four or more additional residential units on any site.|
||Creating four or more additional allotments (excluding lots for the purposes of reserves, network utilities or transport corridors).|
||Involving more than 1ha of land.|
||Creating a new building for industrial activities with a gross floor area greater than 1000m2.|
||Involving any new activity which will have a water requirement greater than 15m3 per day.|
||Creating a new building for non-residential activities (other than industrial activities or
as provided for in vii. below) with a gross floor area greater than 300m2.|
|||vii.||Within the Major Facilities Zone:|
a new building for non-residential activities (other than industrial
activities) with a gross floor area greater than 3,000 m2; or|
residential accommodation for more than 13 additional people, not being
accommodation for hospital patients.|
||This Rule does not apply in areas where an ICMP exists and satisfies the information requirements for Water Impact Assessments in accordance with Table 22.214.171.124b of Volume 2, Appendix 126.96.36.199, or where all the information that a Water Impact Assessment would otherwise include,
or the matters it would otherwise address, are incorporated in a Water Supply
Agreement with Council or other documents, assessed and approved under any
other provision of this District Plan or the Waikato Regional Plan. |
1. As outlined in Volume 2, Appendix
188.8.131.52, Water Impact Assessments are also required as part of the information requirements for activities that do not comply with Rule 184.108.40.206
Water efficiency measures or permeable surface standards for the relevant zone.
2. The 1ha trigger in Rule 220.127.116.11(a)iii) relates to the footprint of the proposed development or subdivision.
