Council continues TIP public hearing to June 17; staff highlights ADA ramps, overlays and Island Crest Way projects
Summary
City staff previewed the draft 2026–2031 Transportation Improvement Program and continued the public hearing to June 17; ongoing and near‑term projects include ADA ramp upgrades, arterial overlays, Island Crest Way crossings and the Town Center commuter parking lot.
The Mercer Island City Council opened a public hearing on the draft 2026–2031 Transportation Improvement Program (TIP) on April 15 and continued the hearing to June 17 to allow additional public comment and to give staff time to incorporate feedback and prepare the street fund forecast.
City Engineer Patrick Yamashita and transportation staff reviewed recent and ongoing projects: ADA transition plan implementation (11 ramps upgraded in 2024 in the Town Center area and ongoing ramp upgrades planned annually), the arterial and residential overlay program (annual hot‑mix asphalt resurfacing), and the Eightieth Avenue sidewalk improvements (sidewalk, street tree, and lighting upgrades with measures such as silver cells to improve tree root growth beneath sidewalks).
The Island Crest Way pedestrian improvements project (rectangular rapid flashing beacons at two crossings and a new pedestrian signal near Island Park Elementary) is expected to reach substantial completion this summer. The Town Center commuter parking facility (former Tully site) is under construction with anticipated substantial completion in June and will provide vehicle and bicycle parking as well as connection improvements to transit stops and the future light‑rail station.
Finance Director Matt Mornick noted many TIP projects leverage outside funding, including approximately $1.3 million in Washington State Transportation grants for the Island Crest Way shared‑use path design and construction. Staff will collect updated pavement condition index (PCI) data later in 2025 to inform future arterial priorities.
Public comment on the draft TIP remains open; council will receive staff‑revised TIP documents and a street fund forecast for adoption consideration on June 17.
