sediment control measures sufficient to retain sediment onsite. Local governments have the authority to <br />attach conditions to the permit to minimize environmental impacts. <br />What if 1 need riprap or retaining walls? <br />The construction or replacement of riprap, retaining walls, or other erosion control structures are allowed by <br />local government permit within: <br />• The shore impact zone or within 50 feet of a public water, wetland, or natural drainage way, <br />whichever is greater <br />• The bluff impact zone <br />Riprap, retaining walls or other erosion control structures would only be allowed to correct an established <br />erosion problem as determined by the local government. Size of structures is limited to that needed to <br />control the erosion problem. The construction of structures below the ordinary high water level always <br />require a DNR permit or approval. <br />River Access on Riparian Lots (part 6106.0140) <br />The MRCCA rules regulate access paths, stairways, water -oriented structures, patios and decks in the <br />following ways: <br />• Driveways or parking areas must meet structure setbacks <br />and cannot be placed in the shore or bluff impact zones. <br />• No impervious surfaces are allowed within the shore or <br />bluff impact zones except for: <br />o Access paths no greater than eight feet wide in <br />the shore impact zone and four feet in the bluff <br />impact zone. <br />o Stairways and lifts no greater than four feet <br />wide - landings may be up to 32 square feet. <br />• Decks and patios may encroach into bluff and river <br />setbacks up to 15% of the required structure setback, <br />provided they don't extend into the bluff impact zone. <br />• One water -oriented accessory structure is allowed for <br />every 300 feet of river frontage. Lots less than 300 feet <br />may have one structure. The water -oriented accessory <br />structure is limited to a 12 foot height, 120 square foot <br />area, and must be at least 10 feet from the water's edge. <br />These structures are not allowed in the bluff impact zone. <br />Structure <br />Setback <br />Shore Impact <br />Zone (SIz) <br />(50%of <br />setback) <br />Water <br />Specifications for facilities on residential lots. <br />Decks/patios <br />may encroach <br />up to 15% into <br />the setback <br />area <br />Water access paths <br />must be <8' in width If in 517, <br />and 5 4' if in BIZ <br />Steirways/iifts <br />must not exceed 4' in width, <br />and landings must not exceed <br />325E <br />Water -oriented accessory <br />Structures <br />must be <_120 SF, at least lb' <br />from shore, and out of the BIZ <br />Minnesota DNR — Division of Ecological & Water Resources April 2016 <br />
