| Engineered High Ground | Retained, engineered or otherwise modified ground along watercourses or the coastline, that is not covered by one of the other defence asset types. Only covers cases where the top of the retaining structure is no higher than the ground behind it, therefore it is not considered a raised flood defence such as a flood wall or embankment. Although it may still provide some flood risk management benefit through retaining the ground or preventing below-ground flooding through underground services and basements. Examples of engineered high ground include river frontage walls or sea frontage walls which are no taller than the ground behind them. If the retaining structure is taller than the ground behind it, it is considered a raised flood defence and should be classified as a flood wall or embankment. If the retained ground acts as a quay or promenade, it should be classified as such. | DR | En_32_40_37 | Line |
