Since their creation in the 1970s, an opening fanfare to a progressive modern residential estate, the three lakes along Billing Brook have suffered from infilling with significant volumes of sediment.
Billing Brook is vulnerable to drying out due to unfavourable geological and soil conditions and is also prone to very rapid responses after heavy rainfall events. As a result, a loss in amenity value, transfer of sediment through the system, and poor water quality has rendered the lakes system prone to misuse, and has shown an increase in pressure on the sensitive habitat.
Three restoration options were highlighted in our feasibility appraisal in the 2017 study, including full river restoration and a dredging programme to renew the lakes. Fast forward to 2018 and our team has just completed detailed technical designs, with supporting ecological and arboricultural work, for comprehensive revival of the three urban lakes including the creation of new wetland habitat which will contribute to public amenity and safe public access.
Key to the project’s success was the improvement of accessible and safe maintenance opportunities to sustain the functioning of the lake in the future. Working alongside the project partnership our specialist team guided the client through the design process.
Communication and stakeholder engagement were key to the project’s success with the partnership including:
- Growing Together
- Environment Agency
- Northampton Borough Council
- Northamptonshire County Council
- Daventry District Council
- David Wilson Homes
- Wildlife Trust
- Brookside Residents Council
- Local residents.
“We started off with some pretty daunting looking environmental challenges which the local community felt very strongly about. Our work with JBA has resulted in an entirely feasible set of solutions to those problems. We’ve been able use this as the basis for raising a six-figure sum to do the construction work, which we hope to commence as soon as the bird nesting season is over,” commented Peter Strachan, Project Lead from Growing Together.
