Detention basins, headwalls, outlet structures, concrete flow channels, riprap channels, and other drainage improvements shall be screened with plant materials and/or berms. Such drainage structures, as appropriate, shall be situated in the least visible location or, if visible, incorporated into the natural curves of the land. Detention basin embankments and the basin itself shall be extensively landscaped with wet site tolerant plant materials, with the intention of recreating a seasonal and high water wet ecosystem. The detention facility shall be sized to accommodate the future growth of vegetation planted in the basin.
