West Linn planners discuss ‘zone-within-a-zone,’ first-floor retail targets and limits on single-use stores for Vision 43

Planning staff presented a package of zoning policy questions for the Vision 43 project on May 21 as the West Linn Planning Commission weighed how to shape mixed‑use development along the Willamette Drive / Highway 43 corridor.

Planning staff Chris said the project aims to “create a new community vision for the, Highway 43 corridor here in West Linn,” and walked commissioners through four policy questions about (1) different development standards for properties on the highway versus behind it, (2) whether to require a percentage of first‑floor space to be commercial, (3) whether to allow single‑use commercial buildings in corridor focus areas and (4) whether to limit maximum size for single‑use buildings.

Why it matters: The corridor zoning decisions will influence what types of stores and housing developers can build, how traffic and parking change in neighborhoods such as Old River Drive and Walling Way, and whether the corridor supports more local shops or national anchors.

Commissioners voiced broad support for differentiated rules that push more intense commercial development to properties immediately fronting Highway 43 while allowing lower‑intensity transitions on the rear, neighborhood side — a so‑called “zone within a zone.” Commissioners described that approach as a way to “preserve that residential feel while still promoting different types of commercial activities,” and to create a transition from the highway into adjacent neighborhoods. No formal motion or code change was adopted at the meeting.

On traffic analysis and infrastructure, commissioners asked about neighborhood impacts if sites off the highway redevelop into mixed use. Staff said Kittelson & Associates, the project transportation consultant, will perform traffic modeling once the project team defines redevelopment parameters. Planning staff noted the transportation analysis is in scope but cannot proceed until assumptions about likely development types and intensities are set.

The commission spent substantial time debating first‑floor commercial requirements. Staff and commissioners listed pros — continuous active frontage and a stronger pedestrian environment — and cons — the risk of vacant storefronts and reduced housing feasibility if ground floors must be commercial in places that lack visibility or foot traffic. One commissioner described the corridor goal as creating “active commercial, housing above, sit‑down sidewalk cafes” along Highway 43, while acknowledging that back‑of‑building spaces or alley‑facing storefronts often cannot support retail.

Commissioners proposed different ways to approach a commercial requirement. Some said a modest required share focused on the facade facing 43 could produce owner‑occupied cafes or small shops; one commissioner suggested a notional 15–20 percent of the ground‑floor frontage as a possible target while others argued that deeper plans or larger footprints could push that figure higher — up to roughly 35–40 percent in some layouts — if the building configuration allows. Staff cautioned that a strict percentage could unintentionally create small, unusable “token” retail spaces or discourage feasible housing mixed‑use projects.

The group also discussed single‑use commercial buildings (for example, large, stand‑alone retailers or gyms). Staff reported there has been little community appetite expressed for big‑box stores on Highway 43 during outreach, but commissioners noted single‑use anchors can also generate positive activity if well‑sited. Planning staff said the city’s general commercial code currently limits total structure size to about 60,000 square feet; commissioners agreed this existing cap reduces the likelihood of very large big‑box stores but asked staff to confirm numeric thresholds and how those limits interact with height, parking and lot constraints.

Quantitative context raised during the discussion: common store sizes cited by staff were Trader Joe’s ~35,000 sq ft, suburban Safeway ~50,000 sq ft, Target ~25,000–45,000 sq ft, Costco ~50,000 sq ft and fitness centers ~20,000–35,000 sq ft. Commissioners also noted Parkrose Hardware in West Linn is about 50,000 sq ft and pointed out that parking needs and lot depth on many corridor parcels will constrain large footprints.

What’s next: Staff said they will gather more detailed information — traffic modeling inputs from Kittelson, interviews with developers, regional examples such as Lake Oswego and The Pearl, and industry standards — and bring that information to City Council later in the summer (council is expected to see related questions in July). Commissioners asked staff to return with options showing how different percentage requirements, frontage definitions and size limits would affect feasibility and likely development patterns.

No formal actions, votes or code amendments were adopted at the May 21 session; commissioners provided policy direction and requested further analysis and examples before any regulatory change is proposed.
