Planning commission recommends park‑zone code updates, adopts lighting and temporary‑structure exemptions

The Mercer Island Planning Commission voted June 10 to recommend the City Council adopt a package of amendments establishing a Park Zone development chapter and related code changes, and approved several specific drafting changes including new lighting standards and an exemption for temporary structures from impervious-surface limits.

The commission also asked the City Council to write to the Washington State Department of Transportation (WSDOT) seeking clarification about whether Aubrey Davis Park — where WSDOT holds certain interests — can be included in the new Park Zone without regulatory conflict.

Why it matters: The Park Zone chapter creates a clearer regulatory framework for parks and recreation facilities on Mercer Island, including rules on permitted uses, trail design and lighting that will guide park projects, permit decisions and capital planning.
