MEMORANDUM To: From: Date: NAC File No: Request: Mayor Stille and St. Anthony Village City Council City Manager Charlie Yunker Stephen Grittman, City Planner City Council Regular Meeting for April 27, 2021 323.02 – 21.01 Amendment Zoning Ordinance section relating to Accessory Building Regulations in All Zoning Districts BACKGROUND AND PLANNING COMMISSION/STAFF RECOMMENDATION City planning staff is proposing an amendment to the City’s Accessory Building regulations that impact a series of current zoning ordinance sections, including changes to the Zoning Ordinance Definitions (Section 152.08), and an overhaul of the Accessory Buildings text (Section 152.176). The material is presented in both table form and a proposed ordinance. The table material identifies proposed language updates to the text. The highlighting is included here to show some of the evolution of the discussion at Planning Commission level, including proposed changes and additions as their review of the issue went forward. Also attached to the staff report is a proposed ordinance form incorporating the amendments. A public hearing was held at the Planning Commission meeting to invite public comment. There was no public comment offered, and the Planning Commission passed a recommendation to adopt the amendments, with one change to the staff item receiving the majority of the discussion. That change related to the allowable size of a detached garage (or “Accessory Building-Major”) on a single family parcel. The existing ordinance includes conflicting requirements, which the proposed amendment would resolve. As currently written in the Definitions section, a “Garage” is allowed to be up to 1,000 square feet in floor area, while in the Accessory Building section of the code, such garages are limited to 750 square feet or 80% of the floor area of the principal building. For background and a reference point, a typical two-car garage would be approximately 450-500 square feet. Thus, 750 square feet would be equivalent to a three-car garage. The original staff report incorporated the 750 square feet/80% threshold into the allowable detached garage size for single family parcels, and would delete the 1,000 square foot reference in the definition. The Planning Commission, after some discussion, chose to change the size threshold from 750 square feet to 1,000 square feet or no more than 100% of the size of the principal building. It was noted in the discussion that provided a parcel can meet setbacks and not exceed the required impervious surface standard, among other regulations, a larger detached garage was preferable to having materials or vehicles stored outside. It was further noted that for most St. Anthony R-1 lots, the impervious surface standard is likely to be the limiting factor. With that discussion and change, the Planning Commission voted unanimously to recommend adoption of the proposed ordinance amendment. 75
