Subp. 2.
Purpose.
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.
Subp. 3.
Rural and open space district (CA-ROS).
A.
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.
B.
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.
Subp. 4.
River neighborhood district (CA-RN).
A.
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.
B.
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 stormwater into the river and enhancing habitat and shoreline vegetation are priorities in the district.
Subp. 5.
River towns and crossings district (CA-RTC).
A.
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.
B.
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 stormwater 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.
Subp. 6.
Separated from river district (CA-SR).

6106.0170 SUBDIVISION AND LAND DEVELOPMENT STANDARDS.
Subpart 1.
Purpose.
The purposes of this part are to:
A.
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;
B.
establish standards for protecting and restoring biological and ecological functions of primary conservation areas on large sites; and
C.
encourage restoration of natural vegetation during development or redevelopment of large sites, where restoration opportunities have been identified in local plans.
Subp. 2.
Applicability.
A.
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:
Subp. 3.
Project information.
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.
Subp. 4.
Design standards.
A.
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.
B.
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:
(4)
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.
C.
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.
D.
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.
E.
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.
F.
Stormwater treatment areas or other green infrastructure may be used to meet the requirements of this subpart if the vegetation provides biological and ecological functions.
G.
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.
H.
Areas that have been set aside under item B must be protected through:
(4)
other arrangements that achieve an equivalent degree of protection as determined by the local government.
I.
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.
J.
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.
Subp. 5.
Land dedication.
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, stormwater management, or other public facilities within the Mississippi River Corridor Critical Area.
