1 2. Management purpose. The RN District must be managed to maintain the 2 character of the river corridor within the context of existing residential and 3 related neighborhood development, and to protect and enhance habitat, parks 4 and open space, public river corridor views, and scenic, natural, and historic 5 areas. Minimizing erosion and the flow of untreated storm water into the river 6 and enhancing habitat and shoreline vegetation are priorities in the district. 7 C. Separated from River(SR). 8 1. Description. The SR District is characterized by its physical and visual distance 9 from the Mississippi River. The district includes land separated from the river by 10 distance,topography, development, or a transportation corridor.The land in this 11 district is not readily visible from the Mississippi River. 12 2. Management purpose. The SR District provides flexibility in managing 13 development without negatively affecting the key resources and features of the 14 river corridor. Minimizing negative impacts to primary conservation areas and 15 minimizing erosion and flow of untreated storm water into the Mississippi River 16 are priorities in the district. The RTC District must be managed in a manner that 17 allows continued growth and redevelopment in historic downtowns and more 18 intensive redevelopment in limited areas at river crossings to accommodate 19 compact walkable development patterns and connections to the river. 20 Minimizing erosion and the flow of untreated storm water into the river, 21 providing public access to and public views of the river, and restoring natural 22 vegetation in riparian areas and tree canopy are priorities in the district. 23 (3) MRCCA district map. The locations and boundaries of the MRCCA districts established by this 24 section are shown on MRCCA Overlay District map which is incorporated herein by reference. 25 The district boundary lines are intended to follow the center lines of rivers and streams, 26 highways, streets, lot lines, and municipal boundaries, unless a boundary line is otherwise 27 indicated on the map. Where district boundaries cross unsubdivided property, the district 28 boundary line is determined by use of dimensions or the scale appearing on the map. 29 (E) Special land use provisions. 30 (1) Purpose. To identify development standards and considerations for land uses that have 31 potential to negatively impact primary conservation areas and public river corridor views. 32 (2) Underlying zoning.

Nonmetallic mining. Nonmetallic mining requires a conditional use permit or interim 42 use permit issued by the local government, subject to the following: 43 1. New nonmetallic mining is prohibited within the shore impact zone and bluff 44 impact zone and within the required structure setback from the bluffline and 45 OHWL; 46 2.
