RiverLink shifts up a gear
08 August 2019
After several years of planning
and preliminary design, work on Lower Hutt’s most
ambitious transformation project is starting to ramp-up.
RiverLink recently recruited a project director to oversee and coordinate the project, the resource consent process is underway, and ground investigations along the river banks to provide the data critical for the design of stop banks, bridges and other structures have begun.
RiverLink will strengthen the flood defenses of central Lower Hutt – upgrading the protection of more than $2 billion worth of homes and business – and improve transport links. The development of a riverside promenade is projected to attract 2600 new residents and 2700 workers to the central city, and is described by one economist as “the switch” that will reinvigorate the central city.
RiverLink is a partnership between Greater Wellington Regional Council, Hutt City Council and the NZ Transport Agency.
Recently appointed RiverLink Project Director Martin White has three decades experience leading urban regeneration, economic development and urban planning projects in Wales, England and New Zealand.
He says RiverLink is a highly complex project entering an important phase.
“For many reasons, RiverLink is crucial to the people of Lower Hutt. We have one opportunity to get such a large scale and highly-detailed project right, so the consents and investigation work currently underway is a critical part of the project.
Ground investigations – including drilling and trenching – have begun along both sides of the river. The data collected will be fundamental to the design of the new stop banks, a proposed pedestrian and cycle bridge and the buildings that will line the promenade. It will also ensure that construction will not affect the Waiwhetu Aquifer.
Meanwhile, RiverLink has appointed Isthmus, Tonkin+Taylor, GHD and Holmes Consulting to take RiverLink through the consenting process. Isthmus was involved in the design of the award-winning New Plymouth Coastal Walkway – a project with strong similarities to RiverLink’s promenade.
Hutt City Council also
recently published its Central City Transformation Plan,
which provides a detailed guide to how the central city
could be developed and reinvigorated with the promenade as
its cornerstone.

Background Frequently Asked
Questions
Q&A
What is RiverLink?
• RiverLink is a
partnership between Greater Wellington Regional Council,
Hutt City Council and the NZ Transport Agency.
•
RiverLink comprises three closely related parts – a
significant strengthening of flood protection, improved and
safer transport links, and the riverside promenade, which is
the focal point for Hutt City Council’s planned
reinvigoration of the central city.
Where is the
project at?
• Preliminary planning and
design for Hutt City Council and Greater Wellington Regional
Council is complete.
• The all-important RMA
consents process is starting
• Geotechnical
ground investigations are underway, which are critical to
the design of structures along the riverbank, such as
bridges, new buildings on the promenade and the new stop
banks, as well as the protection of the aquifer.
•
As RiverLink’s momentum is starting to build, we’re
assembling a dedicated joint project office to oversee and
coordinate the three strands that make up RiverLink.
How much will the project cost?
•
For such a large-scale project, with many moving parts, the
final cost can only be an estimate.
• The
estimated cost, excluding a new Melling interchange, is
around $200
• Hutt City Council and Greater
Wellington Regional Council have already allocated funding
in their long term plans.
When will construction
start?
• The start of construction is
dependent on the work we’re doing now – preliminary
design, the ground investigations and the consents
process.
• We’re aiming to start the first
stage of the flood protection construction in 2022.
•
We’re aiming to start the Promenade and pedestrian bridge
in 2024.
When will RiverLink be
completed?
• RiverLink is a complex,
large-scale project and there are many variables that will
determine the exact completion date. We will update the
programme at key stages as the project progresses.
•
Our best estimate at this point is that the flood protection
and the central city transformation parts of the project
could be completed by 2028.
What’s happening
with property acquisitions?
• GWRC is
currently buying property on a willing buyer/willing seller
basis. It does not intend to resort to the Public Works Act
approach, unless required, and only after the completion of
the designation and consents process.
• So far,
77 of the 118 properties required for the new upgraded flood
protection works have been purchased.
• Another
16 are in negotiation.
• Hutt City Council is
acquiring land for the city transformation parts of
RiverLink
How much has been spent on property
acquisitions so far?
• GWRC has spent $51
million on property acquisitions so far.
• HCC
has spent just over $1 million.
What’s
happening with NZTA’s consents?
• NZTA
has identified a preferred alignment for a new Melling
bridge and intersection.
• It is expected to
complete its detailed business case next year, which is
required before deciding whether they will proceed to
consenting the project.
• No decision has been
made whether NZTA will take part in the combined consenting
process at this stage.
• NZTA is able to join
the consenting process if the timing of NZTA’s decision to
consent aligns with the RiverLink consenting programme.
How does NZTA’s absence from the consents process
affect RiverLink’s timing and the flood protection and
promenade parts of the project?
• RiverLink
will proceed as planned, and we’re hoping NZTA will join
us with the consents process at some point.
•
Without a replacement Melling Bridge, RiverLink achieves a
one-in-200 year return period flood level built into the
current best practice standards of design – a huge
improvement on the one-in-65 year level of protection built
to the standards of the 1970s.
• A requirement
would be established (if NZTA were to not jointly consent
with the project partners) that once the existing Melling
Bridge is replaced it would need to meet the flood capacity
requirements of the 2800 cumec, one-in-440 year flood
including the effects of climate change. This situation
exists for other bridges crossing the river.
When
will the public have its say on RiverLink?
•
There has already been extensive engagement with the public
and key stakeholders.
• This will continue with
informal engagement and project information events to keep
people up to date with the project and design
progress.
• There will be ample opportunity for
the public to give its views and ideas.
• There
will be trials and pilot projects where we test ideas, look
out for Belmont Wetland next to Belmont School, the trial
dog exercise area near to where Waimarie Croquet Club used
to be, cycle and recreation trials in and around the river
bank carpark, and work at the southern end of High St
developed with the businesses in that area.
•
We would expect the statutory consultation on the RMA
process will start in April or May of next year.
•
There will also be a programme of public consultation put in
place as the project progresses.
