– All information is incorporated into an approved Concept Plan for a Major Facility (Rule 17.4); and – Information is accepted as satisfying 25.13.4.1

• Minimises compliance costs

Rule 25.13.4.6 Water Impact Assessments (WIA)

• Response to submissions by WINTEC, Waikato

DHB & Perry Group Ltd

• Exemption from Rule when:

– All information required for a WIA is incorporated into another document assessed and approved under any other provision of the District Plan

• Minimises compliance costs

Rule 25.13.4.2 Stormwater

• (c) amended to ensure consistent terminology

throughout the Plan and with Infrastructure Technical Specifications

– Response to HCC submission

• (d) amended to remove ambiguity: “level”

replaced by “rate and volume”

Rule 25.13.4.3 Wastewater

• Amendments in response to HCC submission

– Ensure consistent terminology throughout Plan and with Infrastructure Technical Specifications – Clearly articulate how wastewater will be managed in:

• Future Urban Zone and
• Large Lot Residential Zone within Ruakura Structure

Plan Area

Amended Rule 25.13.4.5 Water Efficiency Measures

• Requires incorporation of low flow fixtures

and at least one water sensitive technique for each water type into new residential units and

• ther new buildings containing a kitchen,

laundry or bathroom

• Deleted similar requirement for alterations or

additions to existing buildings that add an extra kitchen, laundry or bathroom.

Amended Rule 25.13.4.5 Water Efficiency Measures

(Continued)

• Deletion (referred to on previous slide) makes

rule less onerous and responds to 10 submissions

• Note 4 amended: provides for selection of

rainwater tank capacity using specific design.

– This is a change from the track changes version included in the circulated s.42A report. – Change sought by HCC.

Rule 25.13.4.5 Water Efficiency Measures

(Continued)

• It is recommended Advice Note 4 be amended to

read: “The capacity of rainwater tanks for new buildings should be designed to suit the specific site and

• activity. For example, in order to be an effective

water efficiency measure, the rainwater tank for a typical standalone residential dwelling should be at least 5,000 litres.”

Amended Rule 25.13.4.5 Water Efficiency Measures

(Continued)

• New Note 6: cross references list of water

sensitive techniques in Appendix 1.7 (Regional Council submission)

Amended Rule 25.13.4.4 Water (Continued)

• 25.13.4.4 (c) added

– Clarifies that low flow fixtures are required to be incorporated in alterations or additions to any existing building that adds an extra toilet, kitchen, laundry or bathroom – Response to HCC submission

Rule 25.13.4.6 Water Impact Assessments (WIA)

• Amendment clarifies that an ICMP for any

development or subdivision must satisfy the information requirements for a WIA (Table 1.5.4b of Volume 2, Appendix 1.5.4) in order for the development or subdivision to be exempt from needing a WIA.

– Response to HCC submission.

Appendix 1.5.10 Stormwater Disposal Report

• The amendments in response to HCC:

– Extend the requirement to prepare a Stormwater Disposal Report to any activity not complying with standards in Rule 20.4.1 relating to vegetation trimming and maintenance in Significant Natural Areas – Require the report to include details of any spring

• r groundwater seepage on the site

Appendix 1.7 Definitions “Water Sensitive Techniques”

• Amendments in response to HCC:

– Provide clarity – Ensure benefit will be gained from installing water sensitive techniques by ensuring water entering rainwater tanks or grey-water reuse systems is used for toilet flushing, in addition to any landscape irrigation.

Part 3

Amendments Recommended to be Rejected

Chapter 25.13

• Les Wooldridge

– Doesn’t want rules; wants solutions negotiated – Proposes a community stormwater retention scheme

• Rejected because:

– Inefficient, ineffective at achieving Plan objectives – Not achieve purpose and principles of RMA and River Settlement Act

Policy 25.13.2.1b

• Regional Council seeks amendment to policy:

“development should be located away from the margins of natural watercourses and wetlands”

• Rejected: Difficult to achieve in Hamilton City

and undesirable

25.13.4 Rules – General Standards

• WINTEC & Waikato DHB sought exemption

from:

– 25.13.4.2 (d) re stormwater discharges at or below pre-development levels – 25.13.4.5 re water sensitive techniques – 25.13.4.6 re Water Impact Assessments

• Rejected because want a consistent approach

to managing water infrastructure and effects

• n water. Otherwise undermine objectives.

25.13.4.1 Integrated Catchment Management Plans (ICMP)

• Mangakotukutuku Stream Care Inc. seek

provision in Plan requiring preparation of an ICMP for Mangakotukutuku Steam catchment

• Rejected: relief considered unnecessary –

provisions of Appendix 1.5.5 sufficient.

• Mangakotukutuku ICMP preparation

scheduled for 2014/15

25.13.4.2 Stormwater

• Alexandra Simmons is concerned about effects
• f urban stormwater discharges to stream

through her property in Magnolia Grove, Chartwell: wants stormwater discharges to stream to be stopped.

• Rejected: Relief beyond scope of Plan.

Operational issue

Water Meters

• Mr Brumblecomble seeks water meters be

required for all residential and commercial properties.

• Rejected: Beyond scope of District Plan alone;

LGA 2002 process also required.

Rule 25.13.4.4 b)i Water Metering Infrastructure

• Nagarajah Manoharan & Tania Henebry: don’t want

water meters

• Rule doesn’t require installation of water meters, but

requires provision for each additional allotment or new building for urban uses: “a manifold incorporating a toby valve under a meter box within the road reserve as part

• f water connection infrastructure”
• Water metering is an efficient method to incentivise

more sustainable use of water, so Rule is retained.

Rule 25.13.4.4 b)i Water Metering Infrastructure (continued)

• Ian Bridges’ suggestion of a special rate on

high water users is beyond scope of Plan, so is rejected.

Rule 25.13.4.2 Stormwater

• Hounsell Holdings Ltd, Porter Developments

Ltd, Porter Properties Ltd and Hamilton JV seek to have rule deleted on the basis it duplicates Regional Council controls

• Rejected because RMA, LGA, National Policy

Statement for Freshwater Management and Regional Policy Statement all require HCC to manage stormwater

25.13.4.3 Wastewater

• Fonterra opposes limiting on-site wastewater

treatment and disposal facilities to servicing a single lot because it “would unnecessarily constrain opportunities for efficient and effective service provision”

• Rejected because not:

– most efficient/effective for community – best long-term environmental & health outcomes

25.13.4.4 Water

• Council of Elders seeks inclusion of a policy to

reduce water leakage from City’s water supply network to less than 10 percent over 3 years.

• Rejected: Operational matter beyond scope
• f Plan.

25.13.4.5 Water Efficiency Measures

• Mangakotukutuku Stream Care Inc. Group

seeks inclusion of very detailed principles and requirements relating to the design of stormwater treatment systems.

• Rejected: Inappropriate level of detail for
• Plan. Such detail would be included in ICMP
• r the Infrastructure Technical Specifications

Water Impact Assessments Rule 25.13.4.6 and Appendix 1.5.4

• 8 submitters (including Hounsell Holdings Ltd, Porter

Developments Ltd, Porter Properties Ltd and Hamilton JV) sought

deletion from Rule of need for ICMPs to comply with Appendix 1.5.5 because some existing ICMPs approved as part of Structure Plans may not comply

Water Impact Assessments (Continued)

• Rejected because of risks:

– Adverse effects not managed adequately – Plan objectives not achieved – Purpose and principles of RMA & River Settlement Act

Water Impact Assessments (Continued)

• Fonterra seeks exemption from Rule 25.13.4.6

for activities within Te Rapa Dairy Factory site:

– Efficiency addressed by regional consent and HCC water supply agreement

• Rejected: WIAs address stormwater and

wastewater as well as water supply.

Water Impact Assessments (Continued)

• Fonterra seeks threshold for WIA preparation based
• n daily water consumption, not size of building or

site

• Rejected: The size of a site or building affects

impervious surfacing and runoff, so is an appropriate criterion for determining when WIA is required.
