Introduction The Mississippi River Corridor Critical Area (MRCCA) Chapter guides land use and development along the Mississippi River. Saint Paul contains 17 miles of river and 26 miles of shoreline within its city limits, the longest of any municipality within the Critical Area. While other plans have been adopted as part of the Comprehensive Plan that address the city’s relationship to the Mississippi (e.g. the Great River Passage Master Plan), the Critical Area chapter uniquely responds to the requirements of Minnesota Rules, Chapter 6106, which lays out a regulatory framework to protect the MRCCA’s resources and manage the balance between natural systems, urban development, recreation, and commerce. (Note: The Water Resources Management Chapter contains policies and implementation actions for surface water, groundwater, water supply and distribution, stormwater and wastewater.) Designated by Governor’s Executive Order in the 1970s, the Mississippi River Corridor Critical Area is a land corridor along the Mississippi River in the Twin Cities Metropolitan Area governed by special land planning requirements and land development regulations. These regulations, which are implemented through local MRCCA plans and ordinances, protect and preserve the natural, scenic, recreational, and transportation resources of this section of the Mississippi River. The MRCCA comprises 72 miles of river and 54,000 acres of surrounding land in 30 local jurisdictions. Saint Paul’s portion of the Critical Area is shown on Figure 1. In 1988, the U.S. Congress established the Mississippi National River and Recreation Area (MNRRA), a unit of the National Park System, that shares the same boundary as the MRCCA. The Park’s Comprehensive Management Plan (CMP), signed by the Governor and Secretary of the Interior, incorporates by reference the MRCCA program for land use management. Rather than institute a separate layer of Federal regulations, the MNRRA largely relies on the MRCCA to manage land use within the Park. This reliance establishes a unique partnership and framework for land use management among local, State and Federal governments to protect the intrinsic resources of the Mississippi River Corridor. The City has made significant progress on furthering the goals and strategies laid out in the 2002 Mississippi River Corridor Plan. Through improvements at Lilydale Regional Park, Upper Landing Park, Chestnut Plaza (including City House), Harriet Island Regional Park (including Raspberry Island), both the character of public space at the river’s edge and public access to the river have been greatly enhanced. Individual master plans were prepared for key riverfront development sites – West Side Flats, Upper Landing, Victoria Park and Ford – that took the design guidelines in the 2002 Plan to the next level. These master plans guide private development and public infrastructure consistent with the goals of the Mississippi River Corridor Plan. 238 MISSISSIPPI RIVER CORRIDOR CRITICAL AREA SAINT PAUL FOR ALL
Perhaps most significantly, the City Council adopted the Great River Passage Master Plan in 2013 as an addendum to the Saint Paul Comprehensive Plan. The Great River Passage Master Plan contains guiding principles, goals, objectives and concept plans to connect new and enhanced parks and natural areas along the city’s 26 miles of shoreline with one another and with adjacent neighborhoods. The Master Plan is a community- based vision with a corridor-wide perspective. It identifies transformative recreation and leisure opportunities along the river, and balances them with the protection and restoration of natural resources, adding value to adjacent land uses while respecting community and neighborhood desires for better access to the river. The Plan represents an evolution and refinement of previous efforts, with the addition of specific recommendations that will help Saint Paul work toward enhancing the natural environment and recreational qualities of the river, as well as the livability and economic vitality of the city. In 2017, the City Council adopted the Saint Paul River Balcony Master Plan, looking in more detail at one of the most popular ideas from the Great River Passage Master Plan. The River Balcony is envisioned as a 1.5-mile pedestrian pathway along the downtown bluff from the Science Museum to Union Depot, with connections to both the river’s edge and the rest of downtown. Additional supporting materials for MRCCA Chapter policies can be found in the appendices beginning of page 250. The following goals guide the 1.

The City will utilize the criteria provided in the MRCCA Rules to evaluate potential visual impacts of additional height and if/when mitigation is needed. In some cases, the City may pursue flexibility in building height and/or district designation in the MRCCA ordinance. 1. Ford Site – The underlying zoning districts (F2 Residential Mixed Low, F3 Residential Mixed Mid, F5 Business Mixed and F6 Gateway) allow building heights 7-17’ taller than those permitted in the CA-RTC and CA- UM districts. 2. Shepard Davern – The CA-RTC district allows heights of up to 48’ with a Conditional Use Permit (CUP), whereas the underlying zoning of T3 allows heights of up to 55’ without a CUP. 3. West Side Flats – The CA-UM district allows maximum heights of 65’ without a CUP, while the underlying zoning of T3M (West Side Flats Master Plan) allows building heights of 75’ as-of-right and up to 90’ with a CUP. 240 SAINT PAUL FOR ALL

Appendix B Figure CA-1: Dimensional Standards within the MRCCA - Height Structure Height The height of structures, including accessory structures, is determined by local ordinance, provided that it is no taller than the heights defined for each of the MRCCA districts as defined in Minnesota Rules Section 6106.0120. The height established for each district may also be modified through the Conditional Use Permit process, provided that the specific criteria are met. The defined structure height within each district is as follows: District Height 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. 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 opposing 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. 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.
