Greater Wellington Regional Council, Hutt City Council and Waka Kotahi NZ Transport Agency are working collaboratively on RiverLink to deliver three separate but interdependent projects: Flood protection, Making Places Urban Development Plan, and Melling Transport Improvements.

RiverLink will make Hutt City more resilient, more connected and more vibrant.

Melling Transport Improvements

In January 2020, the Government announced the NZ Upgrade Programme – a major infrastructure funding package. This includes funding for transport improvements at Melling, which will be delivered by the Transport Agency, as part of RiverLink. Construction is expected to begin in late 2022 and be completed in 2026. The transport improvements will include a new Melling interchange, relocating the Melling train station, and better walking and cycling links.

Flood Protection

RiverLink’s flood protection work, delivered by Greater Wellington Regional Council, is expected to safeguard residents from large flood events that could affect up to 3,000 homes, five schools and 600 businesses, with the potential to cause an estimated $1.1 billion worth of damage across the community. Recent flooding events across New Zealand have shown the need for investment in flood protection infrastructure, and the devastating consequences for communities flooded as a result of not doing so.

Urban Growth and Housing

Beyond flood protection and transport upgrades, one of the goals of the RiverLink project is to spur urban growth and encourage the construction of more central city homes in the form of apartments. Hutt City Council has unveiled a Central City Transformation Plan to enable this growth. A new riverbank promenade, and a pedestrian and cycling bridge crossing the river near the relocated Melling station, are key parts of RiverLink that will be delivered by Hutt City Council and transform Lower Hutt.

    Contractors are completed stage 2 of planting at the new Belmont pilot wetland. This wetland is the forerunner for schemes designed to manage stream and stormwater run-off into Te Awa Kairangi / Hutt River, improving its water quality and supporting habitats for wildlife.

    Belmont School and the Hill Road community have been involved in previous plantings, however this phase includes more challenging planting with sedges and water-tolerant plants, so specialist contractors are leading this stage. We look forward to partnering with the school and community for future planting in the area.

    With the recent rain Morphum Environmental Limited Ecological Engineer Stu Farrant visited the wetland. He says "the inlet structures that flow through the wetland are working as designed, protecting the wetland from extreme flows".

    It is hoped that the pilot wetland will help us better understand how we can incorporate wetlands into the design for RiverLink

    This week work began on RiverLink's Belmont Wetland Project. Mulching existing river berm vegetation to remove blackberry and all existing berm trees within the site footprint in preparation of new lower wetland planting.

    In the week commencing 26 August environmental controls, fencing and signage will be in place. Topsoil and filling mounds will be stripped for the upper wetland and excavation of the upper wetland will commence. This material will form mounds in the river berm for planting.

    RiverLink is piloting riverbank revegetation, stream improvements and partial diversion of stormwater through constructed wetlands within the immediate floodplain of Te Awa Kairangi / Hutt River. This pilot project is designed to test the feasibility of constructed wetlands within the modified river corridor to improve the mauri of the stream, habitat for indigenous flora and fauna, stormwater quality and control and understand the short- and long-term maintenance requirements.

    The proposal includes the partial diversion of stream flows from the Belmont catchment through a tiered wetland system. The existing modified stream will continue to carry baseflows up to 5 Litres per second to support fish passage to the upper headwaters. Above this, flows will split between the existing channel and the constructed wetland system to improve water quality.

    To split the proposed stream flow and protect the wetland system, two forebays will be constructed. The first controls flows into the wetland and the second helps trap sediments and spread flows across the full width of the wetland. The wetland comprises a mix of shallow and deep habitats to support a range of indigenous plants specifically chosen to improve water quality. This achieved by a mix of physical settling of sediments as well as complex biological and chemical processes to reduce urban contaminants including metals and nutrients.

    Other features include a podocarp treeland, native shrub river edge protection, pedestrian and vehicle access and carparks, a forebay service area and a grassed areas for gathering and interpretive signage.

    We will be holding a community planting day Mid September so look out for our Facebook event.

    Ground investigations are underway to help us develop the design of the proposed Melling transport improvements and other RiverLink projects. You may notice this work going on back in July near the existing Melling Bridge and work will commence again on 4 November. This round of drilling will be for 1 to 2 weeks.

    What is the purpose of the investigations?

    The Transport Agency will use the information gathered from these investigations to help develop the preliminary design of the preferred interchange option – a diamond interchange connecting directly with Queens Drive. The preliminary design is being developed as a part of the Detailed Business Case (DBC) for the transport improvements.

    The ground information helps us to understand what type of design is needed to construct a resilient bridge and interchange. It’s also important as it will help us ensure that any future transport improvements are designed to protect the Waiwhetu Aquifer – an important water supply for the whole region.

    The DBC is an important phase of the project. The Transport Agency expects to complete and consider the DBC for the Melling transport improvements by early 2020.

    Will I be affected by the ground investigation work?

    There will be work taking place at six sites spread across both sides of the river, in areas around the Melling and Riverbank car parks. One of these sites will be a borehole which will take around four days to complete. The remaining five sites will be CPTs (Cone Penetrometer Tests) which use a cone-shaped instrument to determine how much load can be put on the ground – will take one day each.

    All work will be done between 8am – 5pm, and work areas will be fenced off to keep people safe. Four parking spaces at Melling train station will be temporarily restricted during the borehole work. We do not expect this work to cause any other impact to people using the road or using Melling train station.

    Further ground investigations

    Investigations will then continue at various sites on both sides of the river, from upstream of Melling Bridge to the Ewen Bridge. This work will inform the design of the new stopbanks, a large retaining wall which will support the promenade, piers and abutments for the pedestrian cycle bridge. We also expect the findings to help us understand how a nearby major fault line could impact our designs and how best to protect the aquifer.

    At some locations, there will be limited access to the river and traffic management in place at various times. The map below shows where the work will be done.

Both councils committed to the preliminary design and funding to deliver RiverLink. In 2019 we will start seeking the necessary resource consents.

    Transport Minister Phil Twyford received an onsite briefing recently. It was a great opportunity to welcome him and discuss how RiverLink has the potential to transform Lower Hutt.

    One aspect of a significant project such as RiverLink is making sure that programme outcomes align with the government’s land transport system investment strategy. Taking a fresh look at transport priorities provides an opportunity to maximise project outcomes. An opportunity was recently taken to discuss the importance of RiverLink to the Lower Hutt community.

    While the NZ Transport Agency consider how the new vision for the transport network might apply to the Melling transport improvements project, its full steam ahead for geotechnical investigations.

    The rest of 2018 will be busy for RiverLink as we gather geotechnical information about what’s under the ground. This will help us protect the aquifer as we refine our designs. You can read more about this below.

    You will also see some activity around Belmont School with the construction of a trial wetland. One of the most important aims of RiverLink is to keep our river healthy. Constructed wetlands will filter stormwater runoff before it reaches Te Awa Kairanga / Hutt River.
