Oshkosh sustainability board urges clearer native-planting rules, asks staff for examples and language revisions

The Oshkosh City Sustainability Advisory Board asked city staff on Sept. 5 to clarify language in the city's native-planting ordinance and prepare examples showing when a property needs an exemption versus when intentional landscaping is permitted.

Board members said the ordinance'as written'is often read as covering both small landscaped beds and full-yard turf replacement, and that public confusion could lead to unintended enforcement. A city staff speaker explained the ordinance'"was drafted solely to handle those situations where a property owner wants to choose an alternative over turf grass" and is intended primarily as a process for property owners to secure an exemption from typical long-grass enforcement.

Members questioned how the rules apply to common yard treatments such as berms, border plantings and fenced-in backyards. Staff confirmed that intentional landscaped beds (berms, borders and similar features) are treated as landscaping and not as a turf-replacement native-planting area, but agreed the code language and application materials are unclear and should be revised to make that distinction explicit.

Two technical details repeatedly raised were a 5-foot buffer in side and rear yards included in the current ordinance and the municipal "8-inch" overgrowth threshold used to trigger enforcement. Staff said the 5-foot buffer was chosen based on common practice in other municipalities to reduce perceived impacts on adjoining properties, and that the 8-inch rule is the enforcement threshold the native-planting exemption is designed to address. Board members discussed possible alternatives, including smaller front-yard buffers or no backyard buffer, and suggested considering percentage-based thresholds (for example, a majority native cover) to reduce ambiguity.

The board asked staff to draft clearer ordinance language, produce site-plan examples and identify plant species lists to show which options would require an application. Staff said it will evaluate internal capacity to prepare those materials and, if necessary, refer the request to the city manager for prioritization. A board member also volunteered to invite Wild Ones, a local native-plant advocacy group, to present alternatives at a future meeting.

"I've always been passionate about sustainability for years and years," said a newly introduced member, James Zern, who supported producing clearer public guidance to avoid inadvertent enforcement. The board did not vote on ordinance changes at the meeting and directed staff to return with recommended text, examples and an estimate of staff time needed to complete the work.

Next steps: staff will draft clarifying language and examples; the board will review proposed changes and may recommend adjustments to the 5-foot buffer after seeing clearer illustrations and species guidance.
