Aberdeen - The Den of Maidencraig flood management and wetlands project
Designed to help save houses and businesses in the neighbourhood from being flooded, phase 1 of the Den of Maidencraig flood management and wetlands project has been completed.
The scheme was built in an area of Aberdeen which was affected by flooding in March 2018, will add resilience along with the Stronsay Park flooding scheme to protect dozens of properties downstream including at Fountainhall Road.
Thanks to funding from Interreg, Aberdeen City Council and Bancon Homes, a new safe route to school path between the Maidencraig Housing development and Hazlehead Academy has been created. The improvement helped reduce the flood risk downstream in the area and has created a new home for nature by forming a wetlands area.
The work included the creation of a new path, construction of earth banks, relocation and opening-up of the tributary burn to create space for nature, installing new lighting, and replacing the temporary bridge over the Den Burn.
The path was built on top of an earth bank which is about 2m high and about 5m wide, with shallow sloping sides. In order to safeguard properties downstream from flooding, the bank has also been designed to hold water back in storm events to a depth of up to 1m, and this will be achieved by replacing the temporary bridge with a new one and installing a large drainage pipe underneath. This aims to slow the flow of water in the Den Burn, allowing it to temporarily flood across the boggy area of the Den of Maidencraig during storms.
As part of the works, the tributary burn coming off the hillside at the Lang Stracht was moved and opened up to improve the habitat for wildlife.
The Maidencraig project fits in with other similar flood alleviation, path and environmental schemes in the area, and the work stems from computer modelling carried out after the Den Burn flooded in previous years which pinpointed several areas which could be used to capture the extra water and hold it safely.
Aberdeen City Council public protection vice convener Councillor Lesley Dunbar said: “We’re delighted the Den of Maidencraig scheme is finished and we look forward to seeing how well it will work, alongside the Stronsay Park scheme.
“There have been several areas around the city which have been affected by flooding particularly in recent years, which causes misery and heartache for residents in their homes and businesses.
“One of these areas was around the Den Burn, and City Council offers carried out expansive computer modelling for the water flow, and then designed several schemes which are designed to flood and contain the water.
“We hope that these new schemes will reduce the flood risk in Aberdeen, while at the same time provide more access options for the community and improve the local habitat for wildlife.”
Graeme Reay, land and planning director at Bancon Homes, said: “We were pleased to work with Aberdeen City Council on this project, which will not only assist in the flood management for properties downstream but will also improve pedestrian connectivity for the occupants of Bancon Homes’ Eden at Maidencraig and The Reserve developments as well as existing properties in the surrounding area, while maintaining the integrity of the local nature reserve.”
Aberdeen City Council will issue a public update on phase 2 shortly
