1 4. Mitigation based on the best available engineering and geological practices is <br /> 2 required and applied to eliminate or minimize the risk of slope failure. <br /> 3 b. In the water quality impact zone, development that creates new impervious surface,e-5 <br /> 4 allowed "., +I^II i ceLti-e-n 1 : 14 801111 11 1^x^�,rpt.I ), or fully reconstructs existing <br /> 5 impervious surface of more than 10,000 square feet requires a storm water permit or <br /> 6 approved storm water plan. Multipurpose trails and sidewalks are exempt if there is <br /> 7 down gradient vegetation or a filter strip that is at least five feet wide. <br /> 8 C. In all other areas, storm water runoff must be directed away from the bluff impact <br /> 9 zones or unstable areas. <br /> 10 (5) Development on steep slopes. Construction of structures,impervious surfaces,land alteration, <br /> 11 vegetation removal, or other construction activities are allowed on steep slopes if: <br /> 12 a. The development can be accomplished without increasing erosion or storm water <br /> 13 runoff; <br /> 14 b. The soil types and geology are suitable for the proposed development; and <br /> 15 <br /> 17 (6) Conditions of land alteration permit approval. <br /> 18 a. Temporary and permanent erosion and sediment control measures retain sediment <br /> 19 onsite consistent with best management practices in the Minnesota Stormwater <br /> 20 Manual; <br /> 21 b. Natural site topography, soil, and vegetation conditions are used to control runoff and <br /> 22 reduce erosion and sedimentation; <br /> 23 C. Construction activity is phased when possible; <br /> 24 d. All erosion and sediment controls are installed before starting any land disturbance <br /> 25 activity; <br /> 26 e. Erosion and sediment controls are maintained to ensure effective operation; <br /> 27 <br /> 28 r„o rao+at6eR �, aRagementl. and <br /> 29 g.

All development must: <br /> 33 a. Be consistent with Minn.Stats.ch. 103B, and local water management plans completed <br /> 34 under [Minnesota Rules] chapter 8410; <br /> 35 b. Meet or exceed the wetland protection standards under Minnesota Rules, chapter <br /> 36 8420; and <br /> 37 C. Meet or exceed the floodplain management standards under Minnesota Rules, <br /> 38 chapters 6120.5000-6120.6200. <br /> 39 (K) Subdivision and land development standards. <br /> 40 (1) Purpose. <br /> 41 a. To protect and enhance the natural and scenic values of the MRCCA during <br /> 42 development or redevelopment of the remaining large sites; <br /> 43 b. To establish standards for protecting and restoring biological and ecological functions <br /> 44 of primary conservation areas on large sites; and <br /> 45 C. To encourage restoration of natural vegetation during development or redevelopment <br /> 46 of large sites where restoration opportunities have been identified in MRCCA plans. <br /> 47 (2) Applicability. <br /> 48 a. The design standards in this section apply to subdivisions, planned unit developments <br /> 49 and master-planned development and redevelopment of land involving ten or more <br /> Page 107 of 147 <br />
