River Hull Integrated Our proposals continued What will it all cost? Catchment Strategy G Upland management The table below shows the current estimated costs for the eight components of the strategy. Creating wetland areas or growing biofuels, for example, in upland areas could help reduce flood flows by 3 - 5%. Grant Operational Preferred Approach funding sources are to be explored. Option Name Capital cost cost per year H Existing maintenance requirement A Dredging £750,000 £30,000 Summary Leaflet A commitment is being sought from partners to ensure B New barrage £13,800,000 £75,000 adequate maintenance is undertaken and that appropriate funding is sought to carry out the the necessary activities.

New river and drain surveys and profiles A Dredging the River Hull and removing wrecks The cost of flood damage to farmland, homes, businesses and Up to 50% of the capacity of the river is lost through essential infrastructure siltation, particularly where there are abandoned vessels and Designing and costing new flood structures and replacement pumps unauthorised structures. Water injection dredging between The impact of sea level rise Tickton and the mouth of the river (which removes the need to take dredgings to a licensed landfill site) will reduce flood Environmental impact of recommended components volumes by 10%. What we have ruled out, and why B New barrage at the mouth of the River Hull Diverting water courses to the coast In the short term it is recommended that the current tidal surge Diverting the Holderness Drain east of Hull barrier be used more frequently to keep out the highest tides (twice a year extra on average). In the medium term a new Off-line storage lagoons alongside the river and Holderness Drain barrage is proposed close to the present barrier. There are Closing pumping stations at Hempholme and Wilfholme different possible engineering solutions, but the simplest is a pair of lock-type gates, which will normally remain open. Widening or deepening land drains Increasing pumping at Waterside pumping station, Beverley C New embankments and pumps to Holderness Drain A river barrage near Ennerdale, Hull New larger pumps are needed at East Hull and Great Culvert pumping stations to increase water flow and reduce flooding These options were ruled out for different reasons (singly or in near Tickton and Leven. Tickton Pumping station can be combination) in different locations because: replaced by a weir. New embankments are needed east of Hull They create additional or greater flood risk, often in other to protect housing and farmland from flooding. locations D Bransholme Pumping Station There is insufficient gradient to make them work Yorkshire water is already committing £16m to upgrade its There are more cost effective solutions (for example, one pumping station, which will allow continuing development at offline lagoon would cost £40m - nearly the cost of all the Kingswood and help reduce flood risk in Bransholme. recommended components) This solution works better when we make extra room in the river (via options A and B). E Beverley and Barmston Drain, Dunswell New embankments are needed along parts of the Beverley and Barmston, Western and Fox Drains in Dunswell. This will protect properties west of the A1174. F Hempholme and Wilfholme pumping stations It is proposed to replace the existing pumps and controls to maintain their operational life and improve their efficiency. Renewable energy solutions are being explored to help reduce operational costs. We are exploring transferring operational responsibility for them too. Water injection dredging vessel.
