Blue-green project development stages
We develop blue-green projects in five stages. This process includes feedback from many people, including technical and environmental experts, mana whenua, local community groups and representatives.
Large projects like these can be expensive and disruptive. This five-stage process is expected to help with planning and completion times.
1. Feasibility assessment
A feasibility assessment helps our Healthy Waters department decide:
- if there is a stormwater solution that could reduce flooding
- whether the project is practical and affordable
- whether the project is likely to get Governing Body and central government approval.
2. Concept design
The concept design stage includes:
- an initial business case to predict benefits and costs
- feedback from mana whenua and the local board.
Once this is done, the Governing Body and central government decide whether to approve the project.
3. Preliminary design
If approved, we develop and share the initial design with the community. Once the design is more fully developed, we apply for a resource consent. The resource consent includes:
- possible environmental impacts
- feedback from the community.
4. Detailed design
When resource consent requirements are met, we the create a final business case, which includes:
- detailed costs
- technical design
- engineering plans.
From here, the Governing Body and central government can give approval to begin construction.
5. Construction
When funding and designs are approved, the council can sign contracts with construction partners and construction can begin.
Ongoing blue-green network projects
We are continuing work on these blue-green network projects:
We lodged resource consent for these projects in November 2024. They are expected to move to the detailed design stage in early 2025.
