1. General information
2. Objectives of the intervention
Goals of the intervention
1. Store excess flows from Devonshire Park and Mayfield Road (ref 1);
2. The purpose of the design was also to demonstrate how source control and disconnection measures can be retrofitted into the urban environment with minimal disruption and without detriment to the local community (ref 1);
3. The Government’s flooding strategy will see the delivery of flood and coastal defences by 2027 that will prevent £32bn in economic damage, as well as creating areas to store water during flooding and greater use of nature-based solutions to reduce flood risk (ref 4);
4. Traceroute of the downstream culvert to River Aire, clean and reinstate to provide drainage outlet at the residential home so in the rainy season it can hold extra water (ref 2);
5. Reconstruct severed culvert at residential home (ref2);
6. Provide high level pumped connection to the sewer for residential home foul drainage (ref 2).

Quantitative targets
1. For Devonshire Park : to provide a storage volume of 1,320 cubic metres (ref 1)
2. For Mayfield Road : to provide 220 cubic metres storage volume (ref 1)

Sustainability challenge(s) addressed
Climate change adaptation: What were the goals of the NBS?
Climate change adaptation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
Storage in the form of SUDS was provided in Devonshire Park using a series of “trench-trough” structures. These take the form of troughs or depressions (swales), with gently sloping sides, set over trenches containing underground infiltration tanks or on trenches with high void space. (ref 1)
