These standard shall be applied to the review of any proposed development occurring to reduce <br />non-point source pollutant loadings in storm water runoff. <br /> <br />Existing natural drainageways, natural water storage or retention areas, and vegetated soil surfaces <br />should be used to the greatest extent possible to store, filter and retain storm water runoff before <br />discharge occurs into any public waters. When natural features and vegetation are not available to <br />handle storm water runoff, constructed facilities such as diversions, settling basins, skimming devices, <br />dikes, and manmade waterways and ponds may be used. Preference shall be given to designs using <br />surface drainage, vegetation, and infiltration rather than buried pipes and manmade materials and <br />facilities. Development should be planned and conducted in a manner that will minimize the extent of <br />disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. <br /> <br />Division 145: Wetland Protection and Manaaement <br /> <br />In accordance with the Wetlands Conservation Act of 1991, the fOllowing regulations shall apply to <br />wetland areas: <br /> <br />A. Permanent natural buffer areas and appropriate erosion control measures be taken <br />surrounding wetland areas to prevent sedimentation of the wetland; and <br /> <br />B. Wetlands may not be drained or filled, wholly or partially, unless replaced by <br />restoring or creating wetland areas of at least equal public value. Wetland <br />encroachment must be guided by the following principles in descending order: <br /> <br />1. Avoiding the direct or indirect impact of the activity that may <br />destroy or diminish the wetland; and <br /> <br />2. Minimizing the impact by limiting the degree or magnitude of <br />the wetland activity and its implementation; and <br /> <br />3. Rectifying the impact by repairing, rehabilitating, or restoring <br />the affected wetland environment; and <br /> <br />4. Reducing or eliminating the impact over <br />time by preservation and maintenance operations during the <br />life of the activity; and <br /> <br />5. Replacing or providing substitute wetland resources or <br />environments. <br /> <br />--P:UJP'--':;II'I)J-'-I~ <br />
