KEY discussion points and opportunities A
Garden riverbank frontage issues. Encourage removal of timber revetments and introduce sensitive marginal habitat management.
Public bench & dog swimming area leading to public footpath with a nice view of the river. A good site for awareness noticeboard highlighting RARP.
Increase depth of riparian margin. Landscape riverbank in some areas to improve floodplain connectivity, wetted margin. Tree planting for shade.
Address eroding riverbank (encourage natural scouring / sediment processes) and provide a long-term solution that also retains angler access. Improve river connectivity to ditch network.
Remove c300m of Nicospan riveted riverbank-edge. Improve sinuosity, wetted margin with some tree/ shrub planting in places along TRB. TLB is pretty good.
Reduce impacts from hatch impoundment e.g. Bypass construction, improve fish/eel migration.

Assess flood risk at bridge i.e. 'arch' pinch-point at the bridge causes the river to back up in floods (image) - how might this be reduced? G Explore re-connecting ditch to floodplain via derelict water meadow system u/s of hatch. H
A large section of the riverbank is often over-grazed by sheep. There is almost no tree cover on the TRB. Complete or even partial fencing and tree planting. Landowner historically not in favour of fence - this may change if done sensitively.
Felling c20 Poplar trees in plantation adjoining public footpath. Open up part of the wooded area to provide the general public with a view of the river. Replant with native species.
Garden riverbank frontage issues. Setup 'pilot' project to encourage removal of timber revetments and sensitive marginal habitat management.
ICW - using existing channel? Return river (in-parts) to historic channel?
Public footpath encroachment issues. Estate / Pisc Soc's to discuss 'permissive footpath'. Provide a noticeboard opposite cottages highlighting RARP. L Disused sluice structure impoundment and potential fish migration issues. Unlikely to get permission to remove, but possible to bypass and reintroduce flow to historic channel, diverting river away from the farm.
High quality wetland creation using existing river channel.
Landscaping and re-profiling riverbank. Greater potential to reconnect to floodplain. Fencing along entire length to reduce grazing pressure. Tree planting for shade.
