(c) Deliver wetland features at Ashcombe House to slow and store water close to the source of the Winterbourne

(d) Remove Invasive Non-Native Species from the channel

(g) Deliver water retention measures at Southover School (adjacent to Winterbourne) to engage with schools and reduce run off from carpark and playground.

26/27

(h) remove 100m of the concrete riverbed section adjacent to Bell Lane recreation ground to help with flooding and renaturalise a 125m section of the Lewes Winterbourne, creating an example of the potential for future restoration of heavily modified sections of the river both up and downstream
