Frequently Asked Questions
Parks Landscape Plan
What is a Parks Landscape Plan?
Creating a Park Landscape Plan helps set the direction on how we can enhance the accessibility, safety and function of Bothamley Park, Cannons Creek Park and Cannons Creek Lakes Reserve. The Park Landscape Plan will outline how we can make the most out of each space to best meet the needs of the community now and into the future. The plan will also feed into the wider Porirua Development work programme to improve housing and public spaces in eastern Porirua.
Why do we need a Parks Landscape Plan?
Eastern Porirua has a great diversity of open spaces and recreation facilities, ranging from sports grounds, recreational reserves, scenic reserves,
playgrounds and local neighbourhood parks. However, we know that Bothamley Park, Cannons Creek Park and Cannons Creek Lakes Reserve
need some improvements to ensure they are safe and fit for purpose.
In 2019, the community told us that:
• The three parks are underutilised
• There is low visibility and poor water management
• There is a lack of accessibility and safety
• There is significant water pollution within Bothamley Park due to the old wastewater pipes
• Cannons Creek Park has poor drainage at the bottom of the park
• Cannons Creek Lakes Reserve has issues around public safety, vandalism and anti-social behaviour.
Creating a Parks Landscape Plan will provide the community with an opportunity for how we can enhance Bothamley Park, Cannons Creek Park and Cannons Creek Lakes Reserve to meet the needs of the community now and into the future.
Will you come back to the community for feedback?
Absolutely! We will take all of the community’s feedback gathered in August and September and come back to the community in November 2021 with a draft Parks Landscape Plan for community review.
Where is the draft Spatial Plan?
The draft Spatial Plan is being further developed with input from the Porirua Development’s partners and community board. We acknowledge there has been a delay returning it to the community for comment, but we are working towards this being available in November.
Will we get more community facilities?
The Parks Landscape Plan sets the direction on how we can improve the parks, for example, if there is community support for more facilities, these will be incorporated into the final plan.
Who will deliver the draft Parks Landscape Plan?
The plan will be delivered in partnership between the community, Porirua Development, Porirua City Council and Ngāti Toa Rangitira. The work will be staged and there will be further consultation required before we start making significant changes to the park as outlined in the Parks Landscape Plan.
How can we manage water better?
Why might we need a water management solution in Cannons Creek Park?
Our waterways are feeling the pressure of a growing population and changes to land-use. A review of the quality of freshwater in Porirua (which includes Kenepuru Stream) in 2019 found it to be Grade E, which is the lowest water quality grade. We want to improve water quality for the community by improving the stormwater entering our waterways.
What are the options available to improve water management?
We’ve looked into a variety of options that could help improve stormwater management from holding stormwater on private properties, through to
creating additional pipes on top of the ground. We’ve been investigating the possibility of creating a wetland at the bottom of Cannons Creek Park, as this option has more recreational and water quality benefits for the community.
What is a wetland?
Wetlands are where the water is at or near the surface of the land, or where the land is permanently or temporarily covered by water. They perform many valuable functions; they act like the kidneys of the earth, cleaning the water that flows into them. Wetlands trap soil, filter out nutrients, remove contaminants and can reduce flooding. They also can be designed to include recreational and community benefit such as new paths for walking or biking, as well as support local wildlife.
What are the benefits of a wetland?
A wetland can:
• Improve water quality through careful design
• Control waterflow to protect the environment downstream
• Introduce a wide range of water loving plants
• Filter soil and toxins from the water
• Provide a home for birds and insects
• Provide a space to learn and connect with water
• Reduce the impacts of flooding
Who will deliver the work?
When a stormwater option is approved, construction and infrastructure experts Te Aranga will deliver the work. Te Aranga Alliance is a partnership of construction and infrastructure experts Higgins, Goodman, Beca, Harrison Grierson and Orogen with Kāinga Ora, Porirua City Council and Ngāti Toa Rangitira. They will be responsible for investigating and upgrading key infrastructure as well as preparing land so Kāinga Ora can build more newer, warmer, drier homes.
Upgrading Bothamley Park's wastewater pipes
Why are you upgrading the wastewater pipes?
When it rains, stormwater gets into the pipes. When this happens, untreated sewage overflows from manholes and runs into our waterways. Untreated wastewater getting into the stream poses a risk to our health, kills fish and other life in the stream, and prevents locals from collecting healthy kai moana (seafood).
It is currently estimated that 40,000m3 of untreated wastewater overflows into Kenepuru Stream in a typical year. That’s enough to fill 16 Olympic swimming pools! As more houses are built in the area, this puts even more pressure on Bothamley Park’s wastewater pipe and results in more overflows of untreated sewage.
Will replacing the wastewater pipe solve sewage pollution into our waterways?
Investigation from a range of partners, local government and government agencies has identified three opportunities to help to fix our
1. Upgrade the Bothamley Park wastewater pipe with a newer, larger pipe.
This will be installed along a similar route as existing pipes and where possible, we will lay the pipe underground, rather than across Kenepuru Stream.
2. Build a large wastewater storage tank just north of the Porirua Station carpark.
Wastewater will overflow into this tank when there is not enough capacity in the wastewater network downstream, instead of overflowing into Kenepuru Stream.
3. Renew old, leaky pipes within the eastern Porirua to reduce the amount of stormwater that gets into the wastewater pipe.
Together, these three improvements are designed to significantly reduce overflows of untreated sewage into waterways in eastern Porirua.
How long will it take to replace?
To minimise disruption, we will stage the development for the new wastewater pipe. Following community engagement in 2021, if granted resource consent in mid-2022, we anticipate 3 kilometres of pipe to be replaced by 2025.
Currently there are special places in the park, what will happen to them during the construction?
We have been working with Porirua City Council, Ngāti Toa Rangitira and local community groups to ensure places valued by the community are protected and maintained during construction.
Why are you drilling boreholes in the park?
We are drilling boreholes into the soil to better understand the ground conditions. Currently the wastewater pipe is visible throughout the park near the stream. We’re looking at removing as many of these stream crossings and placing the pipe underground. By drilling boreholes, it will help us to understand the best places for the new wastewater pipe to be laid.
