1 minimizing erosion and flow of untreated storm water into the Mississippi River 2 are priorities in the district. The RTC District must be managed in a manner that 3 allows continued growth and redevelopment in historic downtowns and more 4 intensive redevelopment in limited areas at river crossings to accommodate 5 compact walkable development patterns and connections to the river. 6 Minimizing erosion and the flow of untreated storm water into the river, 7 providing public access to and public views of the river, and restoring natural 8 vegetation in riparian areas and tree canopy are priorities in the district. 9 (3) MRCCA district map. The locations and boundaries of the MRCCA districts established by this 10 section are shown on MRCCA Overlay District map which is incorporated herein by reference. 11 The district boundary lines are intended to follow the center lines of rivers and streams, 12 highways, streets, lot lines, and municipal boundaries, unless a boundary line is otherwise 13 indicated on the map. Where district boundaries cross unsubdivided property, the district 14 boundary line is determined by use of dimensions or the scale appearing on the map. 15 (E) Special land use provisions. 16 (1) Purpose. To identify development standards and considerations for land uses that have 17 potential to negatively impact primary conservation areas and public river corridor views. 18 (2) Underlying zoning. Uses within the MRCCA are generally determined by underlying zoning, 19 with additional provisions for the following land uses: 20 a. Agricultural use. Perennial ground cover is required within 50 feet of the ordinary high 21 water level and within the bluff impact zone. 22 b. Feedlots. New animal feedlots and manure storage areas are prohibited. Existing animal 23 feedlots and manure storage areas must conform with Minnesota Rules, chapter 7020. 24 C. Forestry. Tree harvesting and biomass harvesting within woodlands, and associated 25 reforestation, must be consistent with recommended practices in Conserving Wooded 26 Areas in Developing Communities: Best Management Practices in Minnesota. 27 d. Nonmetallic mining. Nonmetallic mining requires a conditional use permit or interim 28 use permit issued by the local government, subject to the following: 29 1. New nonmetallic mining is prohibited within the shore impact zone and bluff 30 impact zone and within the required structure setback from the bluffline and 31 OHWL; 32 2. Processing machinery must be located consistent with setback standards for 33 structures as provided in section 920(F)(3); 34 3. Only one barge loading area, which must be limited to the minimum size 35 practicable, is permitted for each mining operation; 36 4. New and,where practicable,existing nonmetallic mining operations must not be 37 readily visible and must be screened by establishing and maintaining natural 38 vegetation. The unscreened boundaries of nonmetallic mining areas are limited 39 to only the barge loading area; 40 5. A site management plan must be developed by the operator and approved by the 41 local government before new nonmetallic mining commences. Operations must 42 be consistent with the site plan throughout the duration of operations at the site. 43 The site management plan must describe how the site will be developed over 44 time with an emphasis on minimizing environmental risk to public waters; 45 6. Explain where staged reclamation may occur at certain points during the life of 46 the site, 47 7. Address dust, noise, storm water management, possible pollutant discharges, 48 days and hours of operation, and duration of operations; Page 104 of 160
