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.

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. Recognition, celebration and protection of the defining feature of Saint Paul for
MRCCA chapter: the benefit of the health, safety and welfare of the residents of the city, state,
region and nation
2. Protection and enhancement of the unique urban ecology of the river corridor

3. An economically-vibrant working river
4. High-quality and sustainable development that enhances the natural environment
5. Equitable public access/strong connections to the Mississippi River
6. The river as the backbone of a community-building network that extends beyond
the shoreline and into the fabric of the surrounding neighborhoods
7. Balance between all of the ways the river is a resource to Saint Paul -

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.
