Whangamata Stormwater Master Plan
Project overview
Metis worked with Thames-Coromandel District Council to generate a multi-year programme of stormwater works in Whangamata.
Our approach
- Identify homes and critical infrastructure at greatest risk of stormwater flooding
- Generate mitigation options for each area at risk
- Engage with residents to prioritise mitigation options
- Generate an annualised implementation programme based on resident feedback and available funding
Outcomes
- Improved stormwater management: Proposed works will transport stormwater away from homes and businesses, reducing risk of flood damage
- ‘Bang for buck’: Targeted programme of stormwater works that benefits the most people relative to capital cost
- Climate change resilience: Pipe networks designed to better accommodate climate-change driven increases in rainfall as well as sea level rise
