Resource Consent Application: Change in Use of the Land & Soil Disturbance / Stormwater Management

Included herewith is an application for resource consent for change in use of the land and soil disturbance (in
accordance with National Environmental Standard, Regulations for Assessing & Managing Contaminants in Soil to
Protect Human Health) for both lots, and for stormwater management impermeable surfaces (in accordance with
Rule 7.6.5.1.6) for 21 Tui Street only.

The proposal is to construct foundations and install a totalspan carport on the two referenced properties;

    • 21 Tui Street, Kaikohe (Lot 7 DP 389986) - Aaron J Brunet (BC-2019-491/0)

            o To address breach of NES-CS, refer to enclosed AEE. The attached Silt and Erosion controls have
                 been devised for earthworks within uncontaminated areas of the lots. A combined Remediation

                 Action and Site Management Plan (SMP & RAP) has been recommended which is to instruct
                 earthworks within the identified arsenic hotspot of this lot.

            0 7.6.5.1.6 Stormwater Management: The specified Stormwater Management for this lot has been
                 designed to stormwater neutrality for peak events and therefore there will be no effect caused by
                 the exceedance of the permitted threshold.

    • 23 Tui Street, Kaikohe (Lot 6 DP 389986) - Ronald A Sharp & Zora A Brunette (BC-2019-490/0)

            o To address breach of NES-CS, refer to enclosed AEE. The attached Silt and Erosion controls have
                 been devised for earthworks within uncontaminated areas of the lots. A combined Remediation

                 Action and Site Management Plan (SMP & RAP) has been recommended which is to instruct
                 earthworks within the identified arsenic hotspot of this lot.

We recommend that if the Council felt it needed to, it could repeat the 'soil disturbance' permitted activity
requirements in regard to clause 8(3).

  PART B - ASSESSMENT OF ENVIRONMENTAL EFFECTS

  Your application must include an Assessment of Effects on the Environment. This form and the associated Information
  Requirement Booklet will help you prepare it.

  An assessment of effects is required so that you and others can understand what happens to the environment when
  you carry out the proposed activity. This will help you to propose ways to minimise those effects to the council's
  satisfaction.

  For applications of a complex nature with considerable effects, a full Assessment of Effects in terms of the Fourth
  Schedule of the Resource Management Act 1991 is required. Depending on the scale of the proposed activity and the
  potential effects of the proposal on the environment, a report prepared by a suitably qualified person may be required.

  Please note that the word "environment" can include the surrounding coastal water, adjoining land, any surrounding
  resource users, and local iwi.

  It is advised that you make an appointment with a council officer to discuss your application prior to lodging it. This will
  help you supply all the required information at the onset and ensure the efficient processing of your application.

  A. Description of the Proposed Activity

  A.1          Provide a detailed description of the proposed activity:

               To construct foundations for relocated dwelling and install total span shed at the following three properties;
               · 21 Tui Street, Kaikohe (Lot 7 DP 389986) - Aaron J Brunet (BC-2019-491/0)
               · 23 Tui Street, Kaikohe (Lot 6 DP 389986) - Ronald A Sharp & Zora A Brunette (BC-2019-490/0)

               Refer to enclosed drawings for proposed development locations and earthworks plans.

               Both lots exceed the allowable limits for soil disturbance under the NES-CS and therefore require resource
               consent.

               21 Tui Street also requires resource consent for breaching Rule 7.6.5.1.6 - stormwater management as
               impermeable surfaces exceeds the permitted threshold. This has been addressed in the cover letter of this
               application.

ASSESSMENT OF ENVIRONMENTAL EFFECTS

General - AEE 11

A.2      You must attach a map or aerial photograph that clearly shows the following:

               the location of the proposed activity,
              E the legal boundaries of the property, and neighbouring properties,
              E roads,
              ® the location of any water bodies, i.e. wetlands, streams or rivers, drains, groundwater and coastal
                     water,

               the location of any other resource user in the surrounding area, and
              ® any significant landmarks.

              If the proposed activity involves buildings or structures, then detailed plans of the proposed buildings or
              structures are also required.

B. Actual and Potential Effects on the Surrounding Environment

Provide details of the actual and potential effects of the proposed activity on the surrounding environment. Please
refer to the Fourth Schedule of the Resource Management Act in the information requirement booklet.

A Detailed Site Investigation (DS') Report has been undertaken in accordance with the NES-CS for both lots submitted
in this application, and it was identified that both lots contain a contamination hotspot.

As detailed in the DSI, it is considered that Council Resource Consent for 21 and 23 Tui Street can be lodged on the
condition of further works; hotspot delineation followed by a Site Remediation Action Plan (RAP) and Site Management
Plan (SMP) report being carried out and approved prior to any earthworks commencing.

The SMP will detail how to undertake the proposed works without causing harm to human health.

For earthworks taking place within the non-contaminated areas of the lots, reference is to be made to the enclosed Silt
and Sediment details and works are to be undertaken in accordance with these.

Proposed development and final land-use is in accordance with the zoning of the lots (residential zone).

General - AEE 11

   C.          Positive Effects

  What positive effects will the proposed activity have?

   Housing development. Proposed development and final land-use is in accordance with the zoning of the lots (residential
  zone).

   D. Monitoring

  What, if any, monitoring do you propose to carry out to ensure that the proposed activity does not have any
  adverse effect on the environment?

  There will not be any earthworks undertaken on-site until a Remediaion Action Plan and Site Management Plan (RAP
  & SMP) has been undertaken and approved by council.

  Monitoring will be assessed once the extent of arsenic in soils has been delineated.

  Arsenic is the only identified contaminant within both lots. Arsenic has been identified as two hotspots (one in each lot),
  is relatively immobile in soil so is not considered to be a risk via migration, and does not cause harm via inhalation.

E. Affected Parties

Will the proposed activity have an effect on any resource user, or property owner in the surrounding area?

    E No, explain why not?
            There will be no earthworks undertaken within the contaminated areas of the lots until a remediation action

            plan and site management plan has been undertaken and approved by council. This document will direct
            how to mitigate any effects on surrounding land or people. These documents will ensure minimal affected
            parties from the proposed activity. Any earthworks being undertaken outside of the contaminated areas can
            be done so in accordance with the enclosed Silt and Sediment management details.

           Yes, who?

    If written approvals are obtained from all parties that may be affected by the proposed activity and the effects of
    your proposed activity are minor, then the council is likely to process your application without public notification.

    If written approval cannot be obtained, please suggest ways to reduce the effect on resource u
    neighbouring property owners (mitigation measures).

    Have you consulted with the people/parties who may be affected by your activity?
                                                                                                         Yes

   F. Mitigation of Effects on the Surrounding Environment

  Suggest ways to reduce any adverse effects on the environment or any potentially affected person/party (mitigation
  measures).

  At this stage of the consent application it is considered that the arsenic hotspot delineation and remediation is required,
  as outlined in Section 7.4 of the Detailed Site Investigation (DSI) report. Council Resource Consent for 21 and 23 Tui
  Street can be lodged on the condition of further works;
  · The full extent of arsenic contamination to be delineated and presented in an addendum letter.
  · A suitable remediation strategy developed, presented in a Remediation Action Plan (RAP) and Site
  Management Plan (SMP). This must be undertaken by a Suitably Qualified and Experienced Geoenvironmental
  Engineer (SQEP) and take place prior to any remediation works on-site.

  There will be no earthworks undertaken within the contaminated areas of the lots until a remediation action plan has
  been undertaken and approved by council. This document will direct how to mitigate any effects on surrounding land
  or people. This could include dust management controls and fencing off the affected areas of site to prevent access by
  unauthorised persons.
  Any earthworks being undertaken outside of the contaminated areas can be done so in accordance with the enclosed

Silt & Sediment Control

General

During construction it will be important for the applicant to control the potential mobilisation of silt to prevent it entering
the stormwater systems, to the greatest extent practicable. Some of the silt material will be of a very fine colloidal
nature, inclined to be very slow to settle out and to cause discolouration of waterways.

The following advice is in accordance with ARC Technical Publication GD05 Erosion & Sediment Control.

The best way to minimise erosion and control sediment discharge is by disturbing as little soil as possible at any one time
and maintaining as much vegetative cover as possible. Exposed areas are to be stabilised as soon as possible using the
specified sub-base materials.

All sedimentation controls shall be maintained in place until bare earthworks areas have been stabilised and landscaped
areas seeded and planted.

Slit Fences

Silt fences are useful for small, disturbed areas or sloping areas and are considered appropriate for this site which is small
and relatively flat lying. Silt fences are to be installed along the downslope boundary of each lot. The lots generally slope
gently to the south east.

Clean Water Diversion

Separation of clean and dirty water greatly reduces the effort needed to prevent sediment run-off by limiting the
quantity of run-off that can become contaminated with silt. The site occupies land which is not subject to run-off from
adjoin properties, therefore there is little risk that clean stormwater could enter the site from above. A clearwater
diversion drain is to be installed should any issues be observed

Hay Bales

Hay bales can impound sediment-laden water at points of discharge, but can be problematic if not installed correctly and
become sodden and un-manageable with time. Bales need to be trenched into the ground and securely staked together,
with bale strings positioned on the sides. At this no hay bales are considered necessary

Stabilising Disturbed Ground
Ground that has been disturbed shall be stabilised as soon as possible. Pavements are to be stabilised with the specified
sub-base materials. Landscape areas should be seeded with grass as soon as conditions are suitable for germination.
Grassed areas not being developed should be protected from damage and kept clear from vehicles and stored materials.

On Site Works

Operations involving concrete washings such as water blasting concrete surfaces, washing down equipment, concrete
and tile cutting shall be undertaken with care since these products are highly alkaline and can contain oxides, heavy
metals (copper drill lubricants) and or petroleum products. Release of these products into the stormwater system or
waterways shall be prevented.

    • If washing cement or concrete fines, make sure the wash water is contained on site and the contaminants
        removed preferably by allowing time for the sediment to settle out.
    • When water blasting, contain the run-off. Cement and chemical additives must not be discharged to stormwater
        drains.

Stockpiles

If any stripped topsoil is to be kept on site it shall be compacted into properly formed stockpiles and covered immediately
or stabilised using mulch or seeded. Any run-off from stockpiles must be directed to suitable sediment control measures
as outlined above.

Pumped Water

The need to pump sediment laden water from trenches or foundations on the site is not anticipated. However, should the
need arise dirty water shall be directed to the sediment controls on site. Under no circumstances shall sediment laden
water be pumped off site untreated.

Plant Re-fuelling
To contain any spillage of fuel, oil or similar contaminants vehicles and plant are to be re-fueled on a gravel pad, where
potential spillage can be contained by on site controls. A spill kit comprising saw dust shall be kept on site as a first
defence to deal with any spillages.

Maintenance

Silt controls shall be checked on a regular basis and immediately prior to any forecast for rain. Maintenance shall be
carried out as necessary and any build-up of silt removed following rainfall events.

Stabilised Entrance Ways

Stabilised entranceways are stabilised areas located at any entry or exit point of a construction site. The purpose of a
stabilised entranceway is to prevent site access points becoming sources of sediment and to assist in minimising dust
generation and disturbance of areas adjacent to the road frontage by providing a detined entry and exit point. This
practice should be used at all points of construction site entry and exit with a view to limiting traffic movements to these
entrances only.
The stabilised access way should be in general accordance of the details presented in Figure 2.

Silt Sock - Stormwater Cesspit

To ensure controls are in place to protect the stormwater catchpit on Tui Street, a silt sock can be placed around the inlet
to act as a small sediment trap immediately up-slope of the catchpit. The silt sock needs to completely 'ring fence' the
catchpit. This measure is only suitable for very small catchment areas and therefore appropriate for these developments.
