Planning commission reviews potential zoning ordinance tweaks on patios, event centers and screening

At its June 24 meeting the Rosemount City Planning Commission held an informal discussion about several proposed amendments to the city zoning code, including rules for outdoor dining connected to liquor licenses, standards for commercial event centers in the agricultural district, and landscaping/screening requirements.

Why it matters: Staff framed the items as code “clean‑up” and solicitated commission feedback before drafting formal ordinance language. Changes could affect how restaurants and event venues operate outdoors, where event centers can locate and how screening and parking‑lot landscaping are measured and enforced.

Key topics and staff proposals: Planning staff (Julia) summarized three potential amendments: (1) update §11‑6‑8 (accessory uses) so the zoning code aligns with liquor‑license provisions (§3.1.14) on outdoor patios and fencing; (2) amend §11‑6‑3 (principal commercial uses) to clarify standards for commercial event centers, including whether the current 200‑guest cap should change and whether an owner must reside on the property; and (3) revise §11‑7‑6 (landscaping, screening and buffering) to simplify parking‑lot tree counting and require coniferous trees/shrubs if landscaping is used for screening while removing a specific opacity metric.

Patios and liquor licenses: Commissioners generally supported aligning zoning language with the liquor code to make patio management less restrictive and easier to administer. Staff said the difference emerged during recent liquor permit work for restaurants such as Las Tortillas; under the existing zoning language “an uninterrupted enclosure” with access only through the principal building can be hard to reconcile with modern outdoor dining layouts. “Allowing the city more flexibility in reviewing the patio would make it easier for more interesting places for people to go and eat and drink outside,” Julia said. Commissioners asked about nonconformity and whether existing businesses would need updated licensing; staff said changes would generally be less restrictive and would not require existing licenseholders to re‑sign contracts.

Commercial event centers: Commissioners debated whether the code should keep the current owner‑residency requirement and a 200‑guest cap. The rule was originally written to allow small farm‑based venues (barn weddings) in agricultural areas while limiting intensity. Some commissioners favored keeping a residency requirement as a control on intensity; others said requiring an owner to live on the site is unnecessary and would deter investment. The commission broadly endorsed the use of conditional use permits and site‑specific review to set guest caps, parking and other mitigation rather than an inflexible numeric maximum. As one commissioner summarized, “If the facility is able to hold more than 200 people based on … fire code requirements, then I don't see why we would limit that structure to that.” Staff will prepare draft language that preserves review criteria (parking, ingress/egress, neighbor impacts) and considers geographic boundaries where event centers are allowed.

Landscaping, screening and buffering: Staff proposed allowing parking‑lot trees to count toward the overall site landscaping requirement (currently they are counted separately), a change commissioners supported to simplify requirements and reduce developer confusion. On screening staff suggested requiring coniferous trees/shrubs when landscaping is used for screening but removing a fixed “90% opacity” metric because enforcement and measurement are difficult. Commissioners asked staff to return with more prescriptive, enforceable options—such as minimum planting heights, caliper/height specifications, or spacing counts—and to check peer city practices. Several commissioners noted past cases where plantings failed or did not achieve expected opacity and said rules should focus on durable outcomes and maintenance obligations.

Next steps: Staff will return with draft ordinance language that reflects the commission’s feedback; any formal changes would proceed through public hearings and a council ordinance process.
