The Brief
The Timaru District Council (TDC) was developing a series of documents to shape the future of stormwater infrastructure development throughout the district. We worked with the Council to draft the comprehensive Stormwater Design Guidelines. These guidelines serve as a crucial resource, ensuring TDC meets its obligations under the Resource Management Act (RMA). The guidelines provide guidance on stormwater treatment and attenuation requirements, considerations for receiving environments, and matters of significance to mana whenua.
What We Did
We delivered various detailed design examples to mitigate the impact of stormwater runoff. Working with Timaru District Council, we drafted the Stormwater Design Guidelines to support consistent application across the district.
In addition to the Stormwater Design Guidelines, Timaru District Council was developing a new Infrastructure Design Standard (IDS) to serve as a compliance framework for aspects of the District Plan, with a focus on subdivision, stormwater and transport chapters. Recognising our expertise, we were engaged to undertake a peer review of the draft chapters.
We evaluated the feasibility of implementing the proposed guidelines across a range of development types and assessed the applicability and relevance of the technical design elements within the local context. To support this process, Timaru District Council adopted the Infrastructure Design Standard used by Christchurch City Council, modified to suit Timaru’s requirements and to align with the stormwater guidelines.
We also worked with the Council to provide three development case studies to demonstrate how the IDS chapters would be adopted and how they would work in practice, as well as highlighting any deficiencies.
