07/21/2026 - Mercer Island - City Council Regular Meeting
Published: Jul 21, 2026
Updates on Parks, Arts Council, and Salmon Recovery Efforts
Council member Androl reported on attending the Open Space Conservancy Trust meeting. The trust is using additional park levy money to increase the eradication of non-native species, and the open space remains well-used and beloved. Council member Shay, as council liaison to the Mercer Island Arts Council, congratulated new leadership (Chair Jonathan Harrington, Vice Chair Katie Gratzer) and new members (Kay Huang, Smei Agawa). The Arts Council is focusing on priorities for 2027-28, including the Greta Hackett Sculpture Gallery and strengthening community engagement. Shay also attended a meeting of the Rya 8 salmon recovery council, including a site visit to the Rutled Johnson flood plain restoration project, focusing on salmon habitat restoration and watershed health. Council member Wer thanked parks and recreation staff for summer events and the public works team for utility services.
Upcoming Community Events and Engagement Opportunities Announced
Council member Weinberg announced his next monthly open lunch will be on Saturday, August 15th at 12 PM at Rowan Oak (182572nd Avenue Southeast). He encourages all to attend for open discussion on various topics, including housing policy. He requests attendees order food or beverages and RSVP. Council member Shay mentioned a new event feed, Townies for Mercer Island, created to help residents discover local events. The next all-island arts meeting is scheduled for Monday, August 10th, focusing on preparation for 'Arts on the Island Friday' on August 28th. Shay also noted that his next committee coffee chat will be on August 24th, a Monday, at 7:30 PM at ASA. Council member Androl encouraged attendance at the 'unCorked' event on August 29th, noting it's always a fun event.
City Council Adopts Storm Water Detention Requirements for Town Center
The city council considered Ordinance Number 26C-11, which amends MICC 15.1.020B and the utilities element policy 4.7. This amendment requires on-site storm water detention for developments within the town center and other identified constrained drainage basins. This change removes the option for city engineers to authorize payment of a fee in lieu of on-site detention in these specific areas, thereby ensuring better protection of the storm water system and downstream receiving waters. This action is in direct response to a Growth Management Hearings Board order and state laws (HB 1220 and HB 2266) requiring the city to plan for housing at all income levels, including permanent supportive housing (PSH). Council members discussed the legal mandates from the state, the consequences of non-compliance, and the community's concerns regarding PSH, emphasizing that this ordinance is solely about drainage and not directly related to housing policy, although it is part of the broader compliance effort driven by state legislation.
City Manager Reports on Upcoming Events, Water Plan Update, and Summer Celebration Success
City Manager Jesse Bond provided updates on upcoming events and ongoing projects. He noted the planned cancellation of August council meetings, with the next meeting scheduled for September 1st. The Planning Commission would meet on August 5th due to an inability to form a quorum in July. Updates were given on the Water System Plan, which requires decennial updates for Department of Health approval, with a draft plan expected in November and final adoption in March. Hydrant flow testing was mentioned as a standard procedure that might cause community concern due to water usage, with residents advised to contact customer service for issues. Several community events were highlighted, including 'Mostly Music in the Park,' 'Pride Night in the Park' on July 30th, and a recap of the successful 'Summer Celebration' which saw record attendance, 30 parade entries, over 500 participants, 20 artists, and 38 nonprofit organizations. A safety change for the parade was the elimination of candy being thrown from vehicles. The fireworks show was also praised.
Community Voices Concerns Over State-Mandated Housing Policies
During the city council meeting, several residents spoke during the 'Appearances' portion regarding affordable housing and permanent supportive housing (PSH), specifically in relation to House Bill 2266 and the Growth Management Hearings Board (GMHB) order. Speakers expressed concerns about potential negative impacts of PSH on children, community safety, and the character of Mercer Island, urging the council to vote against related measures and push back against state mandates. They highlighted that Mercer Island is a predominantly single-family residential community with limited resources and services compared to larger cities, suggesting that PSH services are better located in cities like Seattle. Council members Weinberg and Sheay explained that the adopted code changes, including those related to PSH, are legally required by state law (HB 1220 and HB 2266) and the GMHB order. They emphasized that the city has limited discretion and faces significant sanctions, including loss of funding, if it fails to comply. Council members also noted that while they understand community concerns, they must uphold state law and advocate for the city's interests, stressing that homelessness is a societal failure requiring housing solutions and that their decisions are driven by legal obligations rather than staff recommendations alone.
