This project will
Increase native plant coverage across Hamilton
Protect and improve our Significant Natural Areas
Improve water quality in the Waikato River
Our city is made up of gully systems and streams that flow into the Waikato River. Stormwater runoff flows into these streams and can cause erosion, sedimentation, and other water quality impacts.
In the 2018-28 Long Term Plan Council approved $37.5 million for erosion control projects in the city's catchment and gully systems:
Gully remediation work involves maintenance, weeding, controlling pest plants and planting native species, strengthening banks, plus positioning rocks and logs to naturally mitigate erosion. Council works together with residents and community groups to improve our natural habitats for future generations to enjoy.
We'll never stop erosion, but we can help mitigate it so there is less sediment and higher water quality, creating a vibrant environment for plants, birds, eels, fish, and people to flourish.
2018$37.5M dedicated to erosion control projects in the 2018-28 Long Term Plan.
2020Work began on erosion control projects in catchments and gullies around Hamilton.
2028The project is due to be completed by 2028.
These upgrade works were funded in the 2018-28 Long Term Plan.
Erosion rates in New Zealand are naturally very high by world standards, caused by steep slopes, erodible rocks, generally high rainfall and common, high-intensity storms. For these reasons, Hamilton’s gullies are very susceptible to erosion. The impacts of erosion in our gullies include sediment and other materials entering our streams and waterways, affecting water quality and aquatic life.
Some of our construction works will involve water control (such as pipes and drop structures), weeding and replanting native trees, constructing dams for debris, ground recontouring, reinforcing stream banks, and water diversions (where we reduce the speed the water flows). We will also be building paths and boardwalks for public access, ensuring our community can access and enjoy the gully without damaging the natural environment.
When there is a sedimentation problem in our waterways, it causes other ecological issues such as loss of aquatic habitat for eels, frogs, fish, and other wildlife. Water will look muddy, and downstream there will be water quality issues that impact other streams and rivers.
