There are low spots in the park that cause water to pool. This affects the functionality of the park and makes it difficult to maintain, particularly in the winter months. This is common at closed landfill sites.
The pooling water can seep into the landfill and become contaminated, which can potentially affect the water quality downstream.
What we're planning
We will re-level and re-shape the park, ensuring the low spots are removed and that water on the park itself is channelled away and into the drains that border the park. The perimeter drains will also be widened and regraded to allow for improved water flows.
The project is expected to take up to 52 weeks from start to finish but will only occur during the drier summer months. We have asked for permission to do the works over a period of 3-5 years as the work is subject to the availability of suitable fill. During this time, sections of the park will be closed for safety reasons. We will make sure that some of the park stays open throughout the project, but access to parts may be limited.
We will relocate some of the flax samplings that have been planted along the drain edge at the western and southern section of the park during construction and reinstate these upon completion.
What's being improved
- In general, the whole park will be reshaped and lifted up to a maximum of 1.5–2m above the current profile.
- A ridge will be created through the park so the ground slopes away towards the drains.
- New paths will be created to replace the existing paths.
- To help the water flow towards the drains, some of the existing artificial hills will be covered or removed.
- The outcome will be a drier, more functional park with improved water quality downstream of the park.
Timing for this project will be confirmed once we have sourced appropriate quantities of fill.
