The overarching aim was to restore catchment scale processes as much as possible, taking a long term sustainable rather than quick fix approach. Constraints on the scale of restoration included: large housing development close by, lack of a catchment scale management plan, lack of funding and knowledge. Housing developer initially carried out works, resulting in an unstable channel design. Two one in ten year flooding events which occurred in 2009 caused severe incision of the channel up to 2.7 meters, which in total was estimated to have removed 539m3 of material. cbec eco engineering was subsequently contracted to re-design the channel. Step-pool design was chosen based on modelling. Works included bed and bank profiling, and step construction from boulders and smaller cobbles/gravels. Monitoring has indicated that channel design is stable.
