within 45 days after receipt of the plan and ordinance from the Metropolitan Council, the commissioner must review the draft plan and ordinance to determine their consistency with this chapter, with Minnesota Statutes, chapter 116G, and with the comprehensive plan adopted by a local government. The commissioner shall consider the comments submitted by the Metropolitan Council.
Upon completing the review, the commissioner must take an action under subitem (1) or (2) and provide a copy of the decision to the Metropolitan Council and the National Park Service:
approve the draft plan and ordinance by written decision; or
return the draft plan and ordinance to the local government for modifications, with a written explanation of the need for modification.
When the commissioner returns a draft plan and ordinance to the local government for modification, the local government must revise the draft plan and ordinance within 60 days after receipt of the commissioner's written explanation and must resubmit the revised draft plan and ordinance to the commissioner. Upon receiving the revised draft plan and ordinance from the local government, the Metropolitan Council and the commissioner must conduct the review as provided under item D.
If a meeting is requested by the local government or the Metropolitan Council, a final revision need not be made until a formal meeting has been held with the commissioner on the draft plan and ordinance. The request extends the 60-day time limit specified in this item until after the meeting has been held.
The commissioner must grant extensions to local governments if the local government requests an extension in writing and if the local government is making a good-faith effort to meet the submittal deadline. The extension, if granted, must include a timetable and plan for completion of the plan and ordinance.
Within 60 days after receiving the commissioner's approval of a draft plan or ordinance, the local government must adopt the commissioner-approved draft plan and ordinance. The local government must submit a copy of the final adopted plan and ordinance, with evidence of adoption, to the commissioner, the Metropolitan Council, and the National Park Service within ten days after the adoption.
Only those plans and ordinances approved by the commissioner have the force and effect of law.
Once in effect, the local government must implement and enforce the commissioner-approved plan and ordinance.
If a local government fails to prepare and submit a draft plan and ordinance within one year of notification as provided under item A, fails to incorporate necessary modifications as provided under item E, subitem (2), or fails to adopt the commissioner-approved plan or ordinance as provided under item G, the commissioner must:

provide for transportation and public utility development in a manner consistent with this chapter.
Local ordinances must be consistent with the standards in this chapter and must include:
The local ordinance must be structured as an overlay district. If a conflict exists with underlying zoning, the provisions of the overlay district govern. Where specific numeric thresholds or standards are listed in this chapter, those numeric thresholds or standards must be included in the overlay district.
Local governments may, under special circumstances and with the commissioner's prior approval, adopt ordinances that are not consistent with this chapter, provided that the purposes of Minnesota Statutes, section 116G.15, are met and the ordinance is consistent with the plan prepared by the local government and approved according to this chapter. Special circumstances include the following situations:
areas where existing urban, residential, commercial, or industrial development patterns have been in place since before the designation of the Mississippi River Corridor Critical Area and where the majority of the development does not meet the minimum state standards;
areas managed under other water and related land resource management programs authorized by state or federal legislation with goals compatible with this chapter;
existing or planned wastewater, storm water, water supply, or utility facilities and similar physical or infrastructural constraints make the use of particular minimum standards impractical; and
areas where detailed modeling of visual, physical, or other resource impacts has been completed as part of a public planning process.
A local government requesting ordinance flexibility must submit a written request to the commissioner as part of the ordinance submittal required under subpart 3. The request must:
be approved by the governing body with authority to approve the request;
include the proposed ordinance and any associated maps;
include a detailed description of the proposed alternative standards that are not consistent with this chapter, together with documentation that the alternative standards are consistent with the purposes and scope of this chapter;
describe the special circumstances that justify the use of alternative standards;
describe the potential impacts to primary conservation areas and mitigation actions proposed to address the impacts;
include documentation of any input from adjoining local governments, including those with overlapping jurisdiction and those across the river, and from other potentially affected interests, including community members; and
include any other supporting information, maps, and documents that the local government considers necessary to explain the request to the commissioner.
Within 60 days after receiving a complete request for ordinance flexibility as provided in item B, the commissioner must:
make the request publicly available;
evaluate the request based on:
the extent to which the proposed alternative standards satisfy the purposes of Minnesota Statutes, section 116G.15, subdivision 1, and the purposes and scope of this chapter;
the likely impact of the proposed alternative standards on primary conservation areas and public river corridor views;
comments from adjoining local governments and other potentially affected interests; and
the local government's identification of mitigation measures and its commitment to mitigate any adverse impacts resulting from the proposed alternative standards; and
approve or deny the request, state in writing to the local government the reasons for the approval or denial, and suggest any alternative solutions or regulatory approaches that would be granted ordinance flexibility.
State or regional agencies, local park agencies, special purpose units of government, and local governments with parks or other public lands within their jurisdiction must comply with the standards and criteria in this chapter. The agencies and government entities must include the following elements in plans and project designs for parks and other public lands they own or manage within the Mississippi River Corridor Critical Area:
documentation of the location of the park or other owned or managed land within the Mississippi River Corridor Critical Area and recognition of the purposes of the Mississippi River Corridor Critical Area designation and this chapter;
provisions for protection of primary conservation areas and public river corridor views.

January 19, 2017
The purpose of this part is to identify administrative provisions that must be included in local ordinances to ensure that ordinances are administered consistent with the purposes of this chapter.
A local government must consider applications for variances in a manner consistent with Minnesota Statutes, sections 394.27, subdivision 7, and 462.357, subdivision 6. The local government's review must consider the potential impacts of a proposed variance on primary conservation areas, public river corridor views, and other resources identified in the local government's plan.
If a local government determines that a variance would negatively affect primary conservation areas, public river corridor views, or other identified resources, mitigation is required. Mitigation must be proportional to, have a relationship to, and offset the impact on the affected resource as provided in subpart 5.
The local government's findings of fact accompanying the issuance of any variance must include a finding and evidence supporting a finding that the requested variance is consistent with the purposes and scope of this chapter.
The purpose of this subpart is to allow uses and structures that came into existence legally prior to January 4, 2017, and in conformance with then-applicable requirements to continue to exist and be put to productive use.
Local governments may choose to allow lateral expansion of legally nonconforming principal structures that do not meet the setback requirements in part 6106.0120, provided that:
the expansion does not extend into the shore impact zone or bluff impact zone or further into the required setback than the building line of the existing principal structure. See Figure 3; and
the expanded structure's scale and bulk is consistent with that of the original structure and existing surrounding development.
New structures erected in conformance with the setback averaging provisions of part 6106.0120, subpart 3, item D, are considered to be in conformance with local ordinance requirements.
Site alterations that were legally made prior to the effective date of local ordinances adopted under this chapter are considered conforming. Site alterations include vegetation, erosion control, storm water control measures, and other nonstructural site improvements. Expansion of site alterations must comply with this chapter.
In addition to meeting the requirements of Minnesota Statutes, sections 394.301, 394.303, 462.3595, and 462.3597, a local government's review of conditional and interim uses must consider potential impacts of the conditional or interim use on primary conservation areas, public river corridor views, and other resources identified in a local government's plan.
When evaluation and assessment identify a negative impact under item A, issuance of a conditional or interim use permit must include conditions for mitigation according to subpart 5.
In evaluating a request for a variance or conditional or interim use permit, if a local government identifies a potential negative impact to primary conservation areas, public river corridor views, or other resources identified in the local government's plan, the variance or conditional or interim use permit must require mitigation.
Mitigation must be directly related to and must bear a rough proportionality to the impact of the project on primary conservation areas, public river corridor views, and other resources identified in the local government's plan.
An applicant must submit relevant information to the responsible local government to evaluate how any development that requires discretionary action or a permit under this chapter complies with the plans and ordinances adopted under this chapter.
In addition to local government requirements, project information must include the following, unless the responsible local government determines that the information is not necessary:
a detailed description of the project; and
scaled maps and plans, dimensional renderings, maintenance agreements, and other materials that identify and describe:
primary conservation areas;
public river corridor views;
existing and proposed topography and drainage patterns;
proposed storm water and erosion and sediment control practices;
existing and proposed vegetation to be removed and established;
ordinary high water level, blufflines, and all required setbacks;
existing and proposed structures;
existing and proposed impervious surfaces; and
existing and proposed subsurface sewage treatment systems.
Ramps or other facilities to provide persons with disabilities access to the persons' property, as required by the federal Americans with Disabilities Act and the federal Fair Housing Act and as provided by chapter 1341, are allowed, subject to the following standards:

For purposes of this chapter, six districts are established in the Mississippi River Corridor Critical Area, as described in this part, to protect and enhance the resources and features identified in Minnesota Statutes, section 116G.15, subdivision 3.
The six districts are established based on the natural and built character of different areas of the river corridor. All districts include diverse land uses, including parks and open space and scenic, natural, and historic areas.
The rural and open space district (CA-ROS) is characterized by rural and low-density development patterns and land uses, and includes land that is riparian or visible from the river, as well as large, undeveloped tracts of high ecological and scenic value, floodplain, and undeveloped islands. Many primary conservation areas exist in the district.
The CA-ROS district must be managed to sustain and restore the rural and natural character of the corridor and to protect and enhance habitat, parks and open space, public river corridor views, and scenic, natural, and historic areas.
The river neighborhood district (CA-RN) is characterized by primarily residential neighborhoods that are riparian or readily visible from the river or that abut riparian parkland. The district includes parks and open space, limited commercial development, marinas, and related land uses.
The CA-RN district must be managed to maintain the character of the river corridor within the context of existing residential and related neighborhood development, and to protect and enhance habitat, parks and open space, public river corridor views, and scenic, natural, and historic areas. Minimizing erosion and the flow of untreated storm water into the river and enhancing habitat and shoreline vegetation are priorities in the district.
The river towns and crossings district (CA-RTC) is characterized by historic downtown areas and limited nodes of intense development at specific river crossings, as well as institutional campuses that predate designation of the Mississippi River Critical Corridor Area and that include taller buildings.
The CA-RTC district must be managed in a manner that allows continued growth and redevelopment in historic downtowns and more intensive redevelopment in limited areas at river crossings to accommodate compact walkable development patterns and connections to the river. Minimizing erosion and the flow of untreated storm water into the river, providing public access to and public views of the river, and restoring natural vegetation in riparian areas and tree canopy are priorities in the district.
The separated from river district (CA-SR) is characterized by its physical and visual distance from the Mississippi River. The district includes land separated from the river by distance, topography, development, or a transportation corridor. The land in this district is not readily visible from the Mississippi River.
The CA-SR district provides flexibility in managing development without negatively affecting the key resources and features of the river corridor. Minimizing negative impacts to primary conservation areas and minimizing erosion and flow of untreated storm water into the Mississippi River are priorities in the district.
The urban mixed district (CA-UM) includes large areas of highly urbanized mixed use that are a part of the urban fabric of the river corridor, including institutional, commercial, industrial, and residential areas and parks and open space.
The CA-UM district must be managed in a manner that allows for future growth and potential transition of intensely developed areas that does not negatively affect public river corridor views and that protects bluffs and floodplains. Restoring and enhancing bluff and shoreline habitat, minimizing erosion and flow of untreated storm water into the river, and providing public access to and public views of the river are priorities in the district.
The urban core district (CA-UC) includes the urban cores of Minneapolis and St. Paul.
The CA-UC district must be managed with the greatest flexibility to protect commercial, industrial, and other high-intensity urban uses, while minimizing negative impacts to primary conservation areas and minimizing erosion and flow of untreated storm water into the river. Providing public access to and public views of the river are priorities in the district.
The physical boundaries of each district are delineated in the Mississippi River Corridor Critical Area District Map, Minnesota Department of Natural Resources (2016 and as subsequently amended). The map is incorporated by reference, is not subject to frequent change, and is available on the department's website at www.dnr.state.mn.us/waters/watermgmt_section/critical_area/index.html. The commissioner must maintain the map and must amend the map as provided in item C.
The district boundary lines on the Mississippi River Corridor Critical Area District Map are intended to follow the center lines of rivers and streams, highways, streets, lot lines, and municipal boundaries, unless a boundary line is otherwise indicated on the map. Where district boundaries cross unsubdivided property, the district boundary line is determined by use of dimensions or the scale appearing on the map.
The boundaries of a district established under this part must be amended according to subitems (1) to (3).
A local government or a state or regional agency must submit a written request to the commissioner requesting a district boundary amendment. The request must:
be approved by the governing body with the legal authority to make the request for the state or regional agency or local government;
specifically identify the proposed changes to plans and ordinances to address the proposed change;
identify changes in land uses, infrastructure, or other conditions since January 4, 2017, that justify the proposed changes;
identify those local comprehensive plans, regional system statements, state park and transportation master plans, and federal plans that apply to the area proposed for a district boundary amendment;
address potential negative impacts of the proposed change to primary conservation areas, public river corridor views, and other resources and features identified in local governments' plans; and
contain a summary of feedback from affected parties as provided under subitem (2).
The local government or state or regional agency requesting the district boundary amendment must give notice of the proposed district boundary amendment to adjoining or overlapping local governments, the Metropolitan Council, the commissioner, the National Park Service, and property owners in the area directly affected by the proposed district boundary amendments and must conduct a public hearing.
Upon receiving a complete request for a district boundary amendment as provided under subitem (1), the commissioner must consider the request and determine whether to initiate rulemaking to amend the boundary according to Minnesota Statutes, chapter 14. The commissioner must communicate the determination, in writing, to the local government or state or regional agency requesting the district boundary amendment within 60 days after receiving the request.
This subpart does not apply to the defined river corridor boundary.

The purpose of this part is to establish dimensional standards that protect primary conservation areas and public river corridor views from impacts of development and ensure that new development is sited in locations consistent with part 6106.0020.
Structures, including accessory structures as defined by local ordinance, must be no taller than the heights specified for each district:
CA-ROS: 35 feet;
CA-RN: 35 feet;
CA-RTC: 48 feet, provided that tiering of structures away from the Mississippi River and from blufflines is given priority, with lower structure heights closer to the river and blufflines, and that structure design and placement minimizes interference with public river corridor views. Taller buildings are allowed by conditional use permit, as provided under item D, with consideration of the relationship of building height to the mature treeline, where present, and existing surrounding development, as viewed from the ordinary high water level of the opposite shore and from public river corridor views;
CA-SR: height is determined by the local government's underlying zoning requirements, provided the structure height in the underlying zoning is generally consistent with the height of the mature treeline, where present, and existing surrounding development, as viewed from the ordinary high water level of the opposite shore;
CA-UM: 65 feet, provided tiering of structures away from the Mississippi River and from blufflines is given priority, with lower structure heights closer to the river and blufflines, and that structure design and placement minimize interference with public river corridor views. Taller buildings are allowed by conditional use permit, as provided under item D; and
CA-UC: height is determined by the local government's underlying zoning requirements, provided tiering of structures away from the Mississippi River and blufflines is given priority, with lower structure heights closer to the river and blufflines, and structure design and placement minimize interference with public river corridor views.
For the purposes of this subpart, height is determined by applicable local government zoning regulations, provided it is measured on the side of the structure facing the Mississippi River.
The height requirements in item A do not apply to those structures and facilities identified in part 6106.0180 as exempt from these requirements, but meeting the setback requirements of subpart 3.
In addition to the conditional use permit requirements in part 6106.0080, criteria for considering whether to grant a conditional use permit for buildings exceeding the height limits in item A must include:
assessment of the visual impact of the proposed building on public river corridor views, including views from other communities;
identification and application of techniques to minimize the perceived bulk of the proposed building, such as:
placing the long axis of the building perpendicular to the river;
stepping back of portions of the façade;
narrowing the profile of upper floors of the building; or
increasing the setbacks of the building from the Mississippi River or blufflines;
identification of techniques for preservation of those view corridors identified in the local government's plan; and
opportunities for creation or enhancement of public river corridor views.
Structures and impervious surfaces must not be located in the shore impact zone and must meet the following setback requirement from the ordinary high water level of the Mississippi River and other waters within the Mississippi River Corridor Critical Area, as specified for each district:
CA-ROS: 200 feet from the Mississippi River and 150 feet from the Minnesota River and Vermillion River;

CA-UM: 40 feet; and
CA-UC: 40 feet.
The requirements in items A and B do not apply to those structures and facilities listed in part 6106.0180 as exempt from these requirements.
Where principal structures exist on the adjoining lots on both sides of a proposed building site, the minimum setback may be altered to conform to the average of the adjoining setbacks, provided that the new structure's scale and bulk riverward or bluffward of the setbacks required under items A and B are consistent with adjoining development. No structures or impervious surfaces are allowed within the bluff impact zone or shore impact zone, except as specified under part 6106.0180.
Subsurface sewage treatment systems, including the septic tank and absorption area, must be located at least 75 feet from the ordinary high water level of the Mississippi River and all other public waters within the Mississippi River Corridor Critical Area.
Where lots are created after January 4, 2017, lot area and width standards must comply with the requirements of the underlying zoning, except the width of lots abutting the Mississippi River in the CA-ROS district must be at least 200 feet, unless alternative design methods are used that provide greater protection of the riparian areas.
New lots must have adequate buildable area to comply with the setback requirements in subpart 3.

January 19, 2017
The purpose of this part is to establish standards for public facilities that are consistent with best management practices and that protect primary conservation areas. Public facilities serve the public interest by providing public access to the Mississippi River corridor or require locations in or adjacent to the river corridor and therefore require some degree of flexibility.
For the purpose of this part, "public facilities" means public utilities, public transportation facilities, and public recreational facilities.
All public facilities must be designed and constructed to:
minimize visibility of the facility to the extent consistent with the purpose of the facility;
be consistent with the vegetation management standards in part 6106.0150, subpart 5, and the land alteration and storm water management standards in part 6106.0160, including use of practices identified in Best Practices for Meeting DNR General Public Waters Work Permit GP 2004-001, incorporated by reference under part 6106.0090, where applicable. State or regional agencies, special purpose units of government, local park agencies, and local units of government with parks within their jurisdiction are not required to obtain a vegetation management or land alteration permit under part 6106.0150 or 6106.0160, but must apply the standards and criteria that would be applied by local government, were a permit required;
avoid primary conservation areas, unless no alternative exists. If no alternative exists, then disturbance to primary conservation areas must be avoided to the greatest extent practicable, and design and construction must minimize impacts; and
minimize disturbance of spawning and nesting times by scheduling construction at times when local fish and wildlife are not spawning or nesting.
Right-of-way maintenance for public facilities is subject to the following standards:
vegetation currently in a natural state must be maintained to the extent feasible;
where vegetation in a natural state has been removed, native plants must be planted and maintained on the right-of-way; and
chemical control of vegetation must be avoided when practicable, but when chemical control is necessary, chemicals used must be in accordance with the rules, regulations, and other requirements of all state and federal agencies with authority over the chemical's use.
Crossings of public waters or land controlled by the commissioner are subject to approval by the commissioner according to Minnesota Statutes, sections 84.415 and 103G.245. The commissioner must give primary consideration to crossings that are proposed to be located within or adjoining existing rights-of-way for public transportation and public utilities.
Public utilities must, at a minimum, comply with the following standards:
high-voltage transmission lines, wind energy conversion systems greater than five megawatts, and pipelines are regulated according to Minnesota Statutes, chapters 216E, 216F, and 216G, respectively; and
if overhead placement is necessary, utility crossings must be hidden from view as much as practicable. The appearance of structures must be as compatible as practicable with the surrounding area in a natural state with regard to height and width, materials used, and color.
Where public transportation facilities intersect or abut two or more of the districts established under part 6106.0100, the least restrictive standards apply. Public transportation facilities must be designed and constructed to give priority to:
providing scenic overlooks for motorists, bicyclists, and pedestrians;
providing safe pedestrian crossings and facilities along the river corridor;
providing access to the riverfront in public ownership; and
allowing for use of the land between the river and the transportation facility.
Buildings and parking associated with public recreational facilities, except as provided under part 6106.0180, must meet the dimensional standards in part 6106.0120 and must not be placed within the bluff impact zone or shore impact zone.
Roads and driveways associated with public recreational facilities must not be placed in the bluff impact zone or shore impact zone unless no other placement alternative exists. If no alternative exists, then design and construction must minimize impacts to shoreline vegetation, erodible soils and slopes, and other sensitive resources.
Trails, access paths, and viewing areas associated with public recreational facilities and providing access to or views of the Mississippi River are allowed within the bluff impact zone or shore impact zone if design, construction, and maintenance methods are consistent with the best management practice guidelines in Trail Planning, Design, and Development Guidelines, incorporated by reference under part 6106.0090.
Hard-surface trails are not allowed on the face of bluffs with a slope exceeding 30 percent. Natural surface trails are allowed, provided they do not exceed eight feet in width.
Public water access facilities are subject to the following requirements:
Public signs and kiosks for interpretive or directional purposes are allowed in the bluff impact zone or shore impact zone, provided they are placed and constructed to minimize disturbance to these areas and avoid visual impacts on public river corridor views.
41 SR 799
January 19, 2017
The purpose of this part is to provide design standards for private facilities within the Mississippi River Corridor Critical Area that are consistent with best management practices and that minimize impacts to primary conservation areas and other identified resources.
For the purpose of this part, "private facilities" means private roads, driveways, and parking areas; private water access and viewing facilities; decks and patios in setback areas; and private signs.
Except as provided in part 6106.0180, private roads, driveways, and parking areas must:
be designed and constructed to take advantage of natural vegetation and topography so that they are not readily visible;
Private access paths must be no more than:
eight feet wide, if placed within the shore impact zone; and
four feet wide, if placed within the bluff impact zone.
Private water access ramps must:
Design and construction of private stairways, lifts, and landings are subject to the following standards:
stairways and lifts must not exceed four feet in width on residential lots. Wider stairways are allowed for commercial properties and residential facilities held in common, if approved by the local government;
landings for stairways and lifts on residential lots must not exceed 32 square feet in area. Landings larger than 32 square feet are allowed for commercial properties and residential facilities held in common, if approved by the local government;
canopies or roofs are prohibited on stairways, lifts, or landings;
stairways, lifts, and landings must be located in the least visible portion of the lot whenever practical; and
One water-oriented accessory structure is allowed for each riparian lot or parcel less than 300 feet in width at the ordinary high water level, with one additional water-oriented accessory structure allowed for each additional 300 feet of shoreline on the same lot or parcel. Water-oriented accessory structures are prohibited in the bluff impact zone and must:
not exceed 12 feet in height;
not exceed 120 square feet in area; and
be placed a minimum of ten feet from the ordinary high water level.
Local governments may allow decks and at-grade patios to encroach into the required setbacks from the ordinary high water level and blufflines without a variance, in compliance with parts 6106.0150 and 6106.0160, provided that:
the encroachment of the deck or patio into the required setback area does not exceed 15 percent of the required structure setback;
the area of the deck or patio that extends into the required setback area occupies no more than 25 percent of the total area between the required setback and the 15 percent allowance, using the formula below:
[required setback depth (feet) x 0.15 x lot width (feet) x 0.25 = maximum total area]; and
the deck or patio does not extend into the bluff impact zone.
Placement of signs is guided by the local government's underlying zoning, with the additional provisions in items A and B.
If the local government allows off-premise advertising signs, the signs must:
meet all required setbacks and height limits standards of this chapter; and
not be readily visible.
If the local government allows directional signs for patrons arriving at a business by watercraft, the signs:
if located within the shore impact zone, must convey only the location and name of the establishment and the general types of goods and services available;
must be no greater than ten feet in height and 32 square feet in surface area; and
if illuminated, must have lighting that is shielded to prevent illumination out across the river or to the sky.

The purpose of this part is to establish standards that:
sustain and enhance the biological and ecological functions of vegetation;
preserve the natural character and topography of the Mississippi River Critical Corridor Area; and
maintain stability of bluffs and steep slopes and ensure stability of other areas prone to erosion.
This part applies to:
shore impact zones;
areas within 50 feet of a wetland or natural drainage way;
bluff impact zones;
areas of native plant communities; and
significant vegetative stands identified in local governments' adopted plans.
Intensive vegetation clearing is prohibited, except for the following activities, which are allowed by local permit:
clearing vegetation that is dead, diseased, dying, or hazardous;
clearing to prevent the spread of diseases or insect pests;
removal of invasive non-native species;
restoration and erosion control management activities consistent with a plan approved by the local government or resource agency; and
The following activities are allowed without a permit:
selective vegetation removal, including removal for those activities listed under item A, subitems (1) to (3), and removal for other purposes provided that vegetative cover remains consistent with the management purposes of districts under part 6106.0100;
maintenance of existing lawns, landscaping, and gardens;
removal of vegetation in emergency situations as determined by the local government;
right-of-way maintenance for public facilities meeting the standards of part 6106.0130, subpart 4; and
Local governments must not restrict the height of ground cover vegetation in the areas listed under subpart 2, items A to E.
Local governments must regulate intensive vegetation clearing activities identified in subpart 3, item A, through a permit process.
Local government may create a new administrative permit process or use an existing one for intensive vegetation clearing. Appeals of local government decisions on permits are subject to Minnesota Statutes, section 462.357, subdivision 6.
Local governments may delegate the permitting responsibilities described in this subpart to a resource agency or other qualified agent as determined by the local government.
Local governments must require permit applicants to submit information as needed to evaluate permits for consistency with the standards and requirements of this part and parts 6106.0080, subpart 6, and 6106.0160.
Local governments must grant the permit, deny the permit, or grant the permit with conditions necessary to achieve the purposes of this part, as provided under subpart 5.
In reviewing and approving permit applications, the local government must ensure through permit conditions that the following performance standards are met:
development is sited to minimize removal of or disturbance to natural vegetation;
soil, slope stability, and hydrologic conditions are suitable for the proposed work as determined by a professional engineer or resource agency;
clearing is the minimum necessary and designed to blend with the natural terrain and minimize visual impacts to public river corridor views;
any native plant communities removed are replaced with vegetation that provides equivalent biological and ecological functions. If replaced, priorities for restoration are stabilization of erodible soils, restoration or enhancement of shoreline vegetation, and revegetation of bluffs or steep slopes visible from the river;
all other vegetation removed is restored with natural vegetation to the greatest extent practicable. Priorities for replacement are the same as under item D;
any disturbance of highly erodible soils is replanted with deep-rooted vegetation with a high stem density;
vegetation removal activities are conducted so as to expose the smallest practical area of soil to erosion for the least possible time; and
other conditions as determined necessary by the local government to achieve the purpose of this part.
Reestablishment of natural vegetation is required:
as a condition of permits under subpart 5, items D and E;
upon failure to comply with this part; or
The vegetation restoration plan must:
include vegetation that provides suitable habitat and effective soil stability, runoff retention, and infiltration capability. Vegetation species, composition, density, and diversity must be guided by nearby patches of native plant communities;
be prepared by a qualified individual as defined by the local government; and
include a maintenance plan that includes management provisions for controlling invasive species and replacement of plant loss for three years.
The local government must issue a certificate of compliance after determining that the restoration requirements of item B have been satisfied.

January 19, 2017
The purpose of this part is to establish standards that:
protect water quality from pollutant loadings of sediment, nutrients, bacteria, and other contaminants; and
maintain stability of bluffs, shorelines, and other areas prone to erosion.
For the purpose of this part:
"fully reconstructs" means the reconstruction of an existing impervious surface that involves site grading and subsurface excavation so that soil is exposed. Mill and overlay and other resurfacing activities are not considered fully reconstructed;
"storm water management facilities" means facilities for the collection, conveyance, treatment, or disposal of storm water; and
"water quality impact zone" means land within the shore impact zone or within 50 feet of the boundary of a public water, wetland, or natural drainage way, whichever is greater.
Within the bluff impact zone, land alteration is prohibited, except for the following which are allowed by local government permit:
erosion control consistent with subpart 6 and a plan approved by the local government or resource agency;
the minimum necessary for development that is allowed as an exception under part 6106.0180; and
repair and maintenance of existing buildings and facilities.
Within the water quality impact zone, land alteration that involves a volume of more than ten cubic yards of material or affects an area greater than 1,000 square feet requires a permit from the local government, meeting the standards in subparts 5 and 6.
Construction, repair, or replacement of rock riprap, retaining walls, and other erosion control structures located at or below the ordinary high water level must comply with parts 6115.0215, subpart 4, item E, and 6115.0216, subpart 2. The work must not proceed unless approved by the commissioner as meeting all requirements for work in public waters.
Construction or replacement of rock riprap, retaining walls, and other erosion control structures within the bluff impact zone and the water quality impact zone are allowed by local government permit provided that:
if the project includes work at or below the ordinary high water level, the local permit is not approved until the commissioner has approved or permitted the project according to item A;
the structures are used only to correct an established erosion problem as determined by the local government or resource agency;
the size and extent of the structures are the minimum necessary to correct the erosion problem and are not larger than the following, except as specified under subitem (4):
retaining walls must not exceed five feet in height and must be placed a minimum horizontal distance of ten feet apart; and
riprap must not exceed the height of the regulatory flood protection elevation; and
structures may exceed the height limits in subitem (3) only if a professional engineer determines that a larger structure is needed to correct erosion problems.
Repair of existing rock riprap retaining walls and other erosion control structures above the ordinary high water level does not require a local government permit, provided it does not involve any land alteration.
Nothing in this subpart shall be construed to waive any other permit requirements that are required by law.
Local governments must regulate activities identified in subparts 3 and 4 through a permit process consistent with subpart 6 and part 6106.0150, subpart 4.
In reviewing and approving land alteration permit applications, the local government must ensure that:
temporary and permanent erosion and sediment control measures retain sediment onsite consistent with best management practices in the Minnesota Stormwater Manual, incorporated by reference under part 6106.0090;
natural site topography, soil, and vegetation conditions are used to control runoff and reduce erosion and sedimentation;
construction activity is phased when possible;
all erosion and sediment controls are installed before starting any land disturbance activity;
erosion and sediment controls are maintained to ensure effective operation;
In the bluff impact zone, storm water management facilities are prohibited, except by local government permit if:
there are no alternatives for storm water treatment outside the bluff impact zone on the site in question;
the site generating runoff is designed so that the amount of runoff reaching the bluff impact zone is reduced to the greatest extent practicable;
the construction and operation of the facility does not affect slope stability on the subject property or adjacent properties; and
mitigation based on the best available engineering and geological practices is required and applied to eliminate or minimize the risk of slope failure.
In the water quality impact zone, development that creates new impervious surface, as allowed by exemption in part 6106.0180, or fully reconstructs existing impervious surface of more than 10,000 square feet requires a postconstruction storm water management permit from the local government consistent with the following:
if a local government is covered by a municipal separate storm sewer system (MS4) general or individual permit from the Minnesota Pollution Control Agency, then the treatment requirements of the MS4 permit for postconstruction storm water management for new development and redevelopment projects apply;
if a local government is not covered by an MS4 permit, then runoff from the new or fully reconstructed impervious surface must comply with the treatment requirements in the current national pollution discharge and elimination system program permit for construction storm water;
local governments may adopt other treatment requirements approved by the Minnesota Pollution Control Agency instead of those specified in subitems (1) and (2); and
multipurpose trails and sidewalks are exempt from subitems (1) and (2) if there is down gradient vegetation or a filter strip that is at least five feet wide.
In all other areas of the Mississippi River Critical Corridor Area, storm water runoff must be directed away from the bluff impact zone or unstable areas.
A local government may allow structures, impervious surfaces, land alteration, vegetation removal, or construction activities on steep slopes if:
the applicant can demonstrate that the development can be accomplished without increasing erosion or storm water runoff;
the soil types and geology are suitable for the proposed development; and
vegetation is managed according to the requirements of this part.
All development must:
be consistent with Minnesota Statutes, chapter 103B, and local water management plans completed under chapter 8410;
meet or exceed the wetland protection standards under chapter 8420; and
meet or exceed the floodplain management standards under chapter 6120.

The purposes of this part are to:
protect and enhance the natural and scenic values of the Mississippi River Critical Corridor Area during development or redevelopment of the remaining large sites within the corridor;
establish standards for protecting and restoring biological and ecological functions of primary conservation areas on large sites; and
encourage restoration of natural vegetation during development or redevelopment of large sites, where restoration opportunities have been identified in local plans.
Except as provided in item B, this part applies to the following developments involving ten or more acres for parcels that abut the Mississippi River and 20 or more acres for all other parcels within the river corridor boundary, including smaller individual sites within the following developments that are part of a common plan of development but may be constructed at different times:
planned unit developments; and
master-planned development and redevelopment of land.
The following activities are exempt from this part:
minor subdivisions consisting of three or fewer lots;
minor boundary line corrections;
resolutions of encroachments;
additions to existing lots of record;
placement of essential services; and
activities involving river-dependent commercial and industrial uses.
Local governments must require detailed project information and provide for preproject review of all proposed subdivisions, redevelopments, and planned unit developments as provided under part 6106.0080, subpart 6.
Local government ordinances must contain provisions, including incentives, for alternative design methods such as conservation design, transfer of development density, or other zoning and site design techniques that achieve better protection or restoration of primary conservation areas.
Primary conservation areas, where they exist, must be set aside for protection as open areas as provided under item H. However, where primary conservation areas exceed the thresholds in subitems (1) to (4) as a percentage of a parcel, then only the percentage in subitems (1) to (4) must be set aside:
CA-ROS: 50 percent;
CA-RN: 20 percent;
CA-RTC, CA-UM, CA-UC: ten percent; and
CA-SR: ten percent, if the parcel includes native plant communities or provides feasible connections to a regional park or trail system, otherwise no requirement.
If the primary conservation areas exceed the maximum percentage established in item B, then the local government may determine which primary conservation areas are to be protected, with priority given to the protection of native plant communities and natural vegetation in riparian areas.
If primary conservation areas exist but do not have natural vegetation, then a vegetation assessment must be completed for the areas to be protected to determine whether vegetation restoration is needed. If restoration is needed, vegetation must be restored according to part 6106.0150, subpart 6.
If primary conservation areas do not exist on the parcel in question, the local government must determine whether any portions of the site have been identified as potential restoration areas in local plans, according to part 6106.0070, subpart 4. When such areas have been identified, vegetation must be restored consistent with a restoration plan according to part 6106.0150, subpart 6, and the restored area must be set aside as specified in item B.
Storm water treatment areas or other green infrastructure may be used to meet the requirements of this subpart if the vegetation provides biological and ecological functions.
Any land dedicated for public access or public facilities according to subpart 5 may be counted toward the set-aside requirements of this subpart at the discretion of the local government.
Areas that have been set aside under item B must be protected through:
public acquisition by a government entity for conservation purposes;
a permanent conservation easement, as provided in Minnesota Statutes, chapter 84C;
a deed restriction; or
other arrangements that achieve an equivalent degree of protection as determined by the local government.
Permanent protection methods under item H must ensure, within the areas set aside, the long-term management of vegetation to meet its biological and ecological functions, prohibit structures, and prohibit land alteration, except as needed to provide public recreational facilities and access to the river.
Protected open areas must connect open space, natural areas, and recreational areas, where present on adjacent parcels, as much as possible to form an interconnected network.
Local governments that require dedication of land or equivalent amounts of cash for parks and open space under Minnesota Statutes, section 394.25, subdivision 7, or 462.358, subdivision 2b, must encourage dedication of lands suitable for riverfront access, parks, open space, storm water management, or other public facilities within the Mississippi River Corridor Critical Area.
