· A compliance report to demonstrate how the scheme complies with the "Local Standards and Guidance for Surface Water Drainage on Major Development in Oxfordshire";
· Detailed hydraulic calculations including node references with consideration for the worst case 1:100 + 40% event based on using the latest FEH input data and CV values as set out in Local Standards and Guidance for Surface Water Drainage on Major Development in Oxfordshire;
· Fully detailed sustainable surface water drainage layouts;
· Information on how exceedance and flooded volumes will be safely contained with the site boundary.
· Proposed site levels, floor levels and an exceedance plan;
