The current situation is that the water leaving the ditches along School Lane and the ditch running along the other edge of the field for development, merge to go under the road via a culvert and drain in the ditches in the far field and down to the river. At times of significant rainfall especially in winter the drainage from under the road onwards already cannot cope and the road floods significantly. Developing the field will increase the surface water run off and with no provision to improve the downstream drainage the flooding is will worsen.
The planning allows for an attenuation pond which may help to mitigate the increased surface water run off but unless the rate of flow from the under road culvert downstream to the river is improved the current flooding situation is going to worsen. Any future development would exacerbate this further so would need to look at additional downstream capacity, as well as protecting the current drainage ditches and keeping access to them for maintenance (I yearly have a tractor clear vegetation in the ditch and it was needed to be dug deeper after past flooding).
