Existing natural drainage ways, natural water storage or retention areas, and vegetated soil surfaces should be used to the greatest extent possible to store, filter and retain storm water run-off before its discharge occurs into any public waters. When natural features and vegetation are not available to handle storm water run-off, constructed facilities such as diversion ditches, settling basins, skimming devices, dikes and man- made waterways and ponds may be used. Preference shall be given to designs using surface drainage, vegetation and infiltration rather than buried pipes and man-made materials and facilities. Development should be planned and conducted in a manner that will mlnlmize the extent of disturbed areas, run-off velocities, erosion potential and reduce and delay run-off volumes. Subd. 422.11 Wetland Protection and Management. In accordance with the Wetlands Conservation Act of 1991, the following regulations shall apply to wetland areas: a. Permanent natural buffer areas and appropriate erosion control measures be taken surrounding wetland areas to prevent sedimentation of the wetland. b. Wetlands may not be drained or filled, wholly or partially, unless approved and permitted by the Rice Creek Watershed District. replaced by restoring or ci"eating '.vetland areas of at least equal public 'falue. 'Wetland eneroaehmcnt must be guided by the follO\ving principles in descending order: 1. ,^.. void the direct or indirect impact of the activity that may destroy or diminish the wetland. 2. Mlnlmizing the impact by limiting the degree or magnitude of the vletland aeti'lity and its implementation. 3. Rectify the impact by repairing, rehabilitating, or restoring the affected v.'ctland enyironment. 4. Reducing or eliminating the impact oyer time by preservation and maintenance operations during the life of the activity. 5. Replacing or providing substitute '.vctland resources or enyironments. Subd.421.12 Woodland Preservation. In residential areas, structures shall be located in such a manner that the maximum number of woodlands shall be preserved. If large number of trees is cut in residential areas, trees shall be replanted in a density and manner as approved by the City Council. Clear cutting of woodlands for non-agricultural reasons is prohibited, unless the action involves a utility or roadway, required by the public, and includes a reforestation plan as required by the City Council. Subd. 422.13 Erosion and Sedimentation Control. No land occupant or developer in the City shall cause or conduct any land disturbing activity which causes excessive erosion or sedimentation or which results in damage to water or soil resources. All development in the City shall conform to the natural limitations presented by the topography and soil types in order to minimize soil erosion and sedimentation. Erosion and sedimentation controls shall be consistent with the MPCf..'s "Best Management Practices" current City. state and federal regulations. 10
