Barny Posted March 20 Share Posted March 20 Hi. we have planning permission to install a separate access which crosses a ditch. It is just a field access so not worried about fire engines or anything like that. the drainage board have given permission for us to install a culvert and have the access over the top. It is just a 5m stretch of M1 concrete pipe back filled with soil and concrete filled hessan bags on the sides to give a neat edge. We need to have a hard standing for the first 5m from the road - all good! but the council are insisting I submit a structural assessment of the culvert design as a pre planning condition. has anyone had to do one of these and any idea what is needed? I have the technical sheet for M1 concrete pipes - is that sufficient? we had 22 planning conditions for the house where the council were insisting we had consultant write needless and expensive reports , I am loathed to entertain them for a field access (apologies if there are any planning officers reading this). many thanks Link to comment Share on other sites More sharing options...
Temp Posted March 20 Share Posted March 20 Google found these which I've not read.. Culvert design and operation guide.. https://www.gov.uk/flood-and-coastal-erosion-risk-management-research-reports/culvert-design-and-operation-guide Superceded by.. https://www.ciria.org/ItemDetail?iProductCode=C786&Category=BOOK&WebsiteKey=3f18c87a-d62b-4eca-8ef4-9b09309c1c91 And a page on grants.. https://www.gov.uk/countryside-stewardship-grants/installation-of-piped-culverts-in-ditches-rp6#how-much-will-be-paid The latter says it should "foll8w the manufactures instructions". Perhaps the pipe company can provide info on what coverage etc is needed to meet the weight limit? Perhaps you could do a sketch design that's compatible with the above and then just tell the planners that it's been designed in accordance with the above guidance. Cite a few paragraphs ? Something like that. Link to comment Share on other sites More sharing options...
