The work session was the first opportunity to review and discuss the full draft. The work session was productive with good discussion that focused primarily on Chapters 1 and 2. The Planning Commission began discussion of Chapter 3, but did not finish its review and discussion. We expect the next work session to pick up the discussion on Chapter 3 and continue through Chapters 4 and 5. Given that the Planning Commission did not get through the full draft, the agenda for the Joint Work Session will include an overview of the process, the outline/structure of the draft ordinance, summary of key changes in the Zoning Ordinance, followed by detailed discussion and presentation focused on Chapter 2. REVISED Chapter 2: Zoning Districts The Planning Commission had several comments and suggestions to improve the Chapter 2 draft. After the meeting, the edits and modifications as recommended were incorporated into the draft. Please replace Draft Chapter 2 dated April 6, 2023 with the attached Draft dated April 21, 2023. A summary of the changes incorporated as recommended by the Planning Commission are as follows: • Added language to the Introductory summary to reference the Chapter 7 Glossary for defined terms. • Revised the Dimensional Standards table for each Zoning District to remove the “All” Accessory Structure Standards and instead incorporate dimensional standards by each Accessory Building Type. • Clarified the front yard setback standards in the RE, R-1 and TN-O districts. • Revised the Impervious Surface Coverage requirements for each Zoning District to allow a maximum percent without mitigation, and an additional 15% coverage if Best Management Practices (BMPs) are incorporated. • Revised the list of Plats included in the Traditional Neighborhood Overlay District (TN-O) to reflect platting prior to 1981. (Please note that TN-O, as well as the applicable property for designation, will be presented at the work session in detail and will include a map analysis for discussion).

Mendota Heights Zoning Ordinance 2 Chapter 2 DRAFT 4.21.2023 12-2A-4 Zoning Map The boundaries of these Zoning Districts are hereby established as shown on the official map entitled Zoning Map of Mendota Heights, Minnesota, which map is approved and filed in the office of the City Clerk, hereinafter referred to as the “Zoning Map”. Said map and all the notations, references and other information shown thereon shall have the same force and effect as if fully set down herein and is hereby made a part of this Chapter by reference and incorporated herein as fully as if set forth herein at length. 12-2A-5 Boundaries of Districts A. Boundaries Established. 1. Zoning District boundary lines as indicated on the Zoning Map follow lot lines, the centerlines of streets or alleys, the centerlines of streets or alleys projected, railroad right-of-way lines, the center of watercourses or the corporate limit lines, to the extent possible, all as they exist upon the effective date of this Chapter. 2. If Zoning District boundary lines do not follow any of the above-described lines, the Zoning District boundary lines are established as drawn on the Zoning Map. 3. Where a Base Zoning District boundary line divides a lot of record which was in single ownership at the time of enactment of this Chapter and places portions of such lot of record in two (2) or more Base Zoning Districts, any portion of such lot within 50-feet on either side of such Base Zoning District boundary line may be used for either Base Zoning District. However, if any portion of said lot extends beyond the 50-foot limitation, the Base Zoning District line as shown shall prevail. 4. The Minnesota Department of Natural Resources (MNDNR) establishes the boundary lines of the Mississippi River Critical Corridor Area (MRCCA) Overlay District and FEMA establishes the boundary lines of the designated floodplain overlay. These Overlay Districts may be referred to as the Environmental Overlay Districts, and lands affected by these Districts shall be subject to the boundaries as established by the regulatory agency which may be updated from time to time. 5. The Traditional Neighborhood Overlay (TN-O) District shall be inclusive only of those plats identified explicitly within this Ordinance that were established prior to 1981. 6. The Public/Semi-Public Overlay (PSP-O) District shall be established as a use-based district and is only valid if an active use is present on the property, otherwise the Base Zoning District shall regulate the subject property. B. Vacation of Public Ways. Whenever any street, alley or other public way is vacated by official action of the City, the Base Zoning District abutting the centerline of said alley or public way shall not be affected by such proceeding. 12-2A-6 Applicability of Standards and other Jurisdictions. A. This Chapter must be evaluated in coordination with the other Chapters of this Zoning Ordinance, including the standards established in Chapter 4: Building, Character and Design Standards that establishes physical site performance standards and regulations. B. This Chapter establishes that other jurisdictions have authority over certain lands contained within certain Overlay Districts, and in the case of any conflict between regulations the most restrictive standards shall apply, regardless of jurisdiction.

All parcels, lots and land within the City are zoned with a Base Zoning District designation. The Base Zoning Districts establish and assign dimensional standards for all lots, improvements, subdivisions and other uses as described and regulated within this Zoning Ordinance. A parcel of land, development or contiguous area may be subject to an Overlay District which may assign additional dimensional standards and rules or provide certain flexibility from the standards as expressly described in other applicable Chapters or Sections.
