ZETLAND PARK RAIN / ROSE GARDEN
LOCATION : GRANGEMOUTH, SCOTLAND
DATE : 2021 – 2022
PROJECT TYPE : PUBLIC PARK
PHASE OF WORK : COMPLETED
This project is part of Green Action Trust’s 10,000 Raingardens for Scotland campaign and was delivered in Spring 2022. Iglu submitted a successful tender to create a nature-based solution to address flooding issues in Zetland Park through a rain garden within the context of an existing rose garden in a large public park. The project won 1st Prize in the Climate Change Adaptation category at the 2022 Green Flag Awards.

The final design layout was realised through a series of design development sessions with local residents and members of the Rose Garden Action Group (a local community group who maintain the garden). The proposal responded to the site constraints with the rain garden located at the lowest point of the garden where flooding had been concentrated and the rose planting at the higher north side of the garden. Swathes and strips of herbaceous perennials and roses weave through the centre of the garden to create a vibrant mix of colour and texture. A new accessible-for-all path runs alongside the rain garden and a series of oak raised planters were installed for the community to grow their own edible plants, also designed to be accessible for wheelchair users.

VIEW FROM THE ACCESS PATH THROUGH THE GARDEN
The rain garden is a linear sustainable drainage feature located adjacent to the southwestern edge of the garden. It is a ‘free-form swale’ which has shallow sloping sides down to a valley base of approximately 0.5m deep and is planted with a graded profile of aquatic and herbaceous plants that can accommodate changing water levels within the garden.
A series of land drains take excess water from the rose and grass areas and flow into the rain garden. If the water volume become too great for the rain garden there are two overflow features that connect to nearby gulleys and the wider surface water drainage system.
