• Great Ayton Flooding The review of the Stokesley flood modelling data included the Great Ayton settlement as the village formed part of the Environment Agency commissioned Upper Leven Flood Risk Management Strategy study. The review has changed the flood zone 2 and 3 extents on the land in the vicinity of Cleveland Lodge, with the flood zones now aligned with the minor watercourse. The allocation for proposed development at Cleveland Lodge is now all located in flood zone 1. 8
NORTHALLERTON AREA • Northallerton Flooding The proposed Brompton, Northallerton and Romanby Flood Alleviation Scheme planned to commence in spring 2006 was not constructed. Tenders submitted for the scheme exceeded the pre-tender cost estimates and it was not possible to increase the DEFRA grant aid to meet the new anticipated scheme costs. Stage one works, which were small scale relatively low cost measures which could be carried out in a short time frame to provide an immediate reduction in flood risk were completed. These measures included: • Reconstruction of wooden hill bridge in Romanby, this reduced the restriction caused by the bridge; • Meanders on Willow Beck were straightened in the vicinity of Chantry Road, Romanby to improve flows in the watercourse; • Boundary treatments to properties on Chantry Road properties that back onto the Willow Beck were reconstructed to introduce flood defence characteristics; • Flood defences were constructed around Brompton School; • The public highway and public open space areas on the southern end of Water End, Brompton were lowered to create an overflow to improve watercourse flows in flood conditions. The enmainment of ordinary watercourses associated with the proposed Flood Alleviation scheme was enacted. This process confers main river status on critical ordinary watercourses (those ordinary watercourses associated with flood risk affecting properties). The enmainment was originally planned to be enacted on scheme completion, this was to allow the Environment Agency to take over the maintenance of the Flood Alleviation scheme following its completion. The Environment Agency can only carry out works on a main river, the enmainment of the watercourses means that now only the Environment Agency under their permissive powers are able to progress a Flood Alleviation Scheme for Brompton, Northallerton and Romanby. The present position of the scheme is that the 2006 scheme is to be reviewed by the Environment Agency in light of a new system, ‘outcome measures’ for prioritising funding of flood risk management schemes. The scheme review is due to start in April 2009 and should take 12 months to complete. The review is also intended to confirm the robustness of the proposed scheme and help determine the scheme priority within the National programme of flood risk management spending. The 2 flood map extracts show Northallerton and Northallerton North. There are a number of small amendments to the High Street area; these are shown for information but do not affect the allocations. The more detailed Northallerton North plan has been included to show the flood risk in the vicinity of the significant allocations proposed in this area. 9
