<br /> <br />- <br /> <br />~, <br /> <br />I <br /> <br /> <br />LEARN FROM <br />NATURE <br /> <br />Natural streams and floodplains reduce flood damage by reducing <br />water velocity. They also maintain water quality by filtering <br />sediments and pollutants; preserving and recharging groundwater <br />supplies, providing fish and wildlife habitat; and offering areas <br />for community recreation. <br /> <br />Stream bank vegetation is a <br /> <br /> <br />valuable part of the stream <br /> <br /> <br />system. Trees and shrubs along <br /> <br /> <br />a stream can do more than <br /> <br />almost any other single factor to <br />limit flood damage, <br /> <br /> <br /> <br />... Vegetation holds stream <br />baoks together and <br />decreases flow velocity, <br />reducing the risk that the <br />stream will dramatically <br />change course and <br />damage your property. <br /> <br />Many people mistakenly believe that <br />gravel bars block river flows and <br />should be removed. Dangerous <br />gravel accumulations certainly occur, but most of the time <br /> <br />gravel bars help streams maintain a deep channel that minimizes <br /> <br /> <br />... Most gravel bars help <br />prevent flow blockages <br />and debris accumulations <br />that exacerbate flooding. <br /> <br /> <br />. <br /> <br />- <br /> <br />sediment, ice, and <br /> <br />debris <br /> <br />accumulations <br /> <br />which do cause <br /> <br />flooding. <br /> <br /> <br /> <br />I <br /> <br />-.J <br /> <br />
