Condition 1: Stormwater management works Condition 2: Modifications approval Condition 3: Pre-construction meeting Condition 4: Information required for meeting Condition 5: Post-construction meeting Condition 6: Certification of stormwater management works (as-built plans) Condition 7: Contents of plans Condition 8: Operation and maintenance plan Condition 9: Contents of operation and maintenance plan Condition 10: Operation and maintenance plan implementation Condition 11: Amendments to the operation and maintenance plan Condition 12: Maintenance contract Condition 13: Obstruction of waterway Condition 14: Capture and diversion of stormwater Condition 15: Overland flow provided Condition 16: Obstruction of secondary flow paths Condition 17: Maintenance report Condition 18: Contents of Maintenance report Condition 1: Stormwater management works Version A: The following stormwater management works shall be constructed for the following catchment areas and design requirements, and shall be completed prior to discharges commencing from the site: Works to be undertaken Catchment area: impervious Catchment area: pervious Design requirement(s) [List all treatment devices, roof materials, outfalls, planting that are required] [State the catchment area: impervious in hectares (ha)] [State the catchment area: pervious in hectares (ha)] [List all standards that the treatment device is required to achieve, as defined by TP10 and TP 108] Version B: The following stormwater management shall be constructed for the following catchment areas and design requirements, and shall be completed prior to construction of further impervious surfaces: Works to be undertaken Catchment area: impervious Catchment area: pervious Design requirement(s) [List all treatment devices, roof materials, outfalls, planting that are required] [State the catchment area: impervious in hectares (ha)] the catchment area: pervious in hectares (ha)] [List all standards that the treatment device is required to achieve, as defined by TP10 and TP 108] construction
plans and cross sections of all stormwater management devices, including confirmation of the Water Quality Volume, storage volumes and levels of any outflow control structure; the surveyed locations of all soak installed for the management of stormwater discharges to ground shall be measured to the nearest 0.1 metre with co-ordinates expressed in terms of NZTM; the soakage capacities of the soak holes; and documentation of any discrepancies between the design plans and the plans approved by the Modifications Approval condition. Guidance Note: This condition is to be included in all consents with stormwater works. This condition ensures that the provided As-Built Plans are provided before the meeting and that the plans include all the required information. It is important to have access to accurate As-Built Plans for the monitoring, for the duration of the consent. This condition should be separate from the meeting condition for compliance purposes. Having a timeframe in the conditions is important in to find and allow time to remedy any issues onsite. This is especially important if the works have been carried out incorrectly and may result in adverse effects (i.e. downstream flooding, erosion at outfall etc.). The timeframe should be the same for this condition as for the post-construction meeting timeframe for consistency. Ideally, the plans should be available on or before the post-construction meeting. An expectation of what the should include is provided as a list to ensure that all the relevant information is supplied. When a clause of this condition is not relevant, delete or add wording as required. Clause d and e should only be included if soakholes are part of the consented stormwater management system. Clause (f) is included for the consent holder to identify any minor changes so that these can be approved by the Modifications Approval condition (condition 2 above). Condition 8: Operation and Maintenance Plan An Operation and Maintenance Plan shall be submitted to the Team Leader [specify area] Monitoring for approval. Guidance Note: This condition is to be included in all consents with stormwater management works. This condition ensures that a plan is in place for the ongoing operation and maintenance of the proposed device(s). In most cases, an Operation and Maintenance Plan will have been submitted with the consent application.
