Planning commission advances new park zone, approves park-related code and map changes

Mercer Island Planning Commission on May 28 advanced a package of code and comprehensive‑plan amendments to create a new “park zone,” approving a set of development standards and map changes while directing staff to refine remaining language.

The commission voted on multiple motions during a nearly four‑hour meeting. The body approved the set of minor code edits, adopted several major changes recommended by staff or commissioners, removed an exemption for synthetic turf athletic fields, and approved two new lighting rules intended to limit shoreline glare and protect fish and birds. The commission also voted to change the zoning and the land‑use designation for Aubrey Davis Park from public/institutional/linear park references to the new park category and to add “boathouse” to the recreational‑facilities definition.

Why it matters: the new park zone and the companion comprehensive‑plan edits are the city’s tool for translating the PROS (parks, recreation and open space) master plan into enforceable rules on what can be built in parks, how large structures can be, how trails and lighting are treated, and how shoreline access is configured. Commissioners said the amendments are intended to protect park character while clarifying review processes for future improvements.

That vote carried the staff‑recommended baseline language into the draft recommendation.

- Purpose statement clarified: The commission approved an amendment to the park‑zone purpose statement inserted language reading, in part, “the purpose of the park zone is to preserve and maintain parks, which provide green space, shoreline access, and conservation opportunities,” as moved by Commissioner Acuse and approved by roll call. Commissioner Acuse described the edit as intended to align the code with the PROS plan and to explicitly note shoreline access and conservation opportunities. Commissioner Acuse said, "the purpose of the park zone is to preserve and maintain parks, which provide green space, shoreline access, and conservation opportunities." (motion passed.)

- “Social spaces” language: The commission added the phrase “social spaces for individuals and gatherings” to the purpose statement to recognize spaces that can be programmed or used for gatherings; that amendment passed on roll call.

- Public art / arts process: The commission adopted staff’s alternative wording expanding the definition of public art to clarify installations can be standalone or incorporated into other structures. The motion to add a broader new term ("arts amenities") failed; instead the commission…
