Greenbelt Advisory Commission debates adding 'cultural significance' to agricultural scoring; wetlands and recreation measurement draw strong discussion

ANN ARBOR, Mich. — At an electronic meeting March 6, the Ann Arbor Greenbelt Advisory Commission (GACC) discussed a staff proposal to add a “cultural significance” category to the commission’s agricultural scoring rubric and reviewed proposed changes to open-space scoring, including whether wetlands should remain an explicit scoring item and how to measure recreation potential.

The proposal, presented by staff lead Rosie, would replace the previous “scenic value” measure with a checklist-style “cultural significance” category. Rosie said the new category is meant to be legally permissible, measurable and to “generate some positive social outcomes that complement our conservation goals.” She described possible checklist items that applicants could self-identify, including whether a farm produces food or fiber for local markets, incubates new or beginning farmers, increases affordable land access, forms part of a land-succession plan, or holds special historic status such as a centennial farm. Rosie also proposed an “anomalous” subcategory for truly rare cultural or historic features, joking that such claims would be verified: “I’m gonna demand that I see the mammoth skeleton if that becomes part of that.”

Why it matters: the Greenbelt scoring system is the primary tool GACC uses to rank and prioritize land for conservation easements or fee-simple acquisition. Changes to the scoring system will affect which properties are prioritized for city-funded preservation and how limited Greenbelt funds are allocated.

Staff framed the cultural-significance category as a mostly agricultural measure tied to land use and transfer practices. Councilperson Malek, speaking from Okemos, offered a concrete example for “unique products”: “That is a unique local product that could then be sold at the Ann Arbor Farmers Market or something like that,” Malek said, describing on‑farm processing (for example, a farmer turning milk into yogurt) as the kind of locally distinct product the rubric should recognize.

Commissioner Dee and others debated the breadth and labeling of the category. Dee asked for examples of “unique products,” and the group discussed whether to label one checklist bucket “anomalous” or choose another term to capture rare but measurable cultural or community benefits. Rosie and staff said they would refine the language and provide clearer definitions in application guidance so commissioners know how staff will evaluate claims.

Open-space scoring: wetlands, groundwater recharge and recreation

The commission next reviewed proposed changes to the open-space scoring sheet. Staff proposed retaining measures for natural-area maturity, parcel size and road frontage but reconsidering how water-related features are counted. Rosie suggested dropping a separate explicit “wetlands” line because the current sheet already contains several water-related measures, and because other vegetation communities (for example, remnant prairie) can also be ecologically important. Remi and others pushed back: “I’m on team wetlands all day,” Remi said. Kate and other commissioners argued to keep wetlands explicitly called out or ensure wetlands and floodplains are specifically scored within a water-resources category.

Kate, representing Huron River Watershed Council on parts of the discussion, said: “If we are gonna remove wetlands and floodplains entirely, I’d argue that that water resources category would then need to call out wetlands and floodplains specifically. … intact wetlands are also some of the most bio‑diverse ecosystems.” Rosie agreed to reinsert wetlands or otherwise ensure they are clearly captured by the water-resources measurement.

Commissioners also discussed the road-frontage metric, which staff said is intended to proxy development pressure and, for fee-simple purchases, access and safety (visibility, potential for parking areas). Several commissioners questioned whether road frontage is the best or fairest proxy for recreational value and development pressure because higher road frontage also increases ecological “edge” effects. Commissioners suggested adding an explicit “recreation potential” category rather than relying on road class or vehicle‑trip proxies. One participant summarized the tension: road frontage can indicate both higher development pressure (which argues for protection) and more edge/fragmentation (which can lower ecological value). Rosie said staff would explore adding or sharpening a separate recreation-potential measure and would provide more precise definitions in the application materials.

Data layers and cross-checks

Staff noted several data layers and assessments they are using or proposing to use when scoring: the Huron River Watershed Council’s BioReserve mapping (remapped recently), a parcel-priority layer tied to the city’s strategic plan, a groundwater-recharge layer matched to the Blue Belt assessment, and the National Wetland Inventory for wetlands identification. Rosie said she will propose parcel-priority usage to avoid double-counting the same underlying dataset.

Budget and related updates

Staff also provided a brief budget update. An updated Greenbelt fund balance as of Dec. 31, 2024, was reported at roughly $5,000,400 (previously shown around $5,000,800 using an earlier cutoff). Rosie said several closed projects (Heller closed in January) will be reflected in coming open-session budget materials and that staff plan to take GACC-approved items to city council in April with open-session items appearing in May.

Decisions and next steps

Commissioners did not set final point weights or adopt the proposed category language at the March 6 meeting. Staff will revise the cultural-significance wording, reinsert or explicitly capture wetlands/floodplain measures in the water-resources category, and draft a separate recreation-potential measurement for discussion. Rosie said she will circulate a fresh blank scoring worksheet and asked commissioners to reassign points as homework before the next GACC meeting. The commission scheduled its next meeting for April 3.
