Council approves $260,348 amendment for town center planning; public commenters press for clearer SEIS details

The Sammamish City Council on Sept. 2 authorized a $260,348 amendment to the Framework LLC contract to continue work on the town center subarea plan and related code updates, advancing a multi-step process that staff said will continue into 2026.

The amendment, moved and seconded during the meeting and approved after debate, adds consultant resources for finalizing the supplemental environmental impact statement (SEIS), additional stakeholder outreach, affordable-housing viability analysis and a 3-D visual model of a buildout scenario. Community Development Director David Pyle told the council the amendment would bring total project spending to about $728,000 and that the final SEIS was targeted for release around Sept. 12.

Council and staff framed the amendment as a step to move from environmental analysis toward code and design work. Pyle said public comment during the SEIS process was larger than expected and that staffing transitions had increased near-term reliance on consultants. He said the additional work will include a Kidder analysis of affordable-housing viability, more landowner and agency meetings (including Eastside Fire and school districts), alignment with public works standards, and a 3-D “observer fly-through” model so residents can see code outcomes.

Public commenters used the meeting to press the city on specifics the draft SEIS did not provide. Resident Richard Johnson urged the council to “audit” the traffic model in the draft SEIS, saying comparisons with adjacent jurisdictions and the Washington State Department of Transportation show inconsistencies at key intersections. Mary Wictor, speaking online, said Sammamish needs “diverse, smaller housing” in town center to help financial sustainability. Paul Stickney urged the city to first quantify citywide affordable- and market-rate housing needs before committing to town center growth. Several commenters, including Stephanie Vallea and Heather Murphy Raines, raised environmental and process concerns and urged council to delay final decisions until after the upcoming general election so newly elected council members could weigh in; Raines cited petition and survey opposition in the community.

Pyle walked through the schedule: the city expects to issue the final SEIS in mid-September, begin planning commission work the week of Sept. 18, and carry the code amendment work into 2026 with design and development-rule work continuing into the next year. He reported $468,000 already spent on the project and said Framework’s amendment would add the $260,348 requested without requiring a budget amendment because of staff salary savings and reallocated transportation consultant time.

Council discussion emphasized the need for clarity on traffic findings and for cost-benefit detail on code choices. Deputy Mayor Amy Lam and Council member Pamela Stewart asked for a clearer breakdown of how different code options would affect traffic and feasibility, and asked for the underlying traffic modeling assumptions and sensitivity analyses. Pyle and staff committed to additional data in advance of upcoming planning commission sessions.

The council vote to authorize the amendment passed (motion carried). Staff will publish the final SEIS and proceed with the expanded outreach and code work; no land-use regulations take effect until the code amendments complete the public-review process and any formal adoption steps required by state law.

Why it matters: the town center subarea plan is the city’s first large subarea implementation of the newly adopted comprehensive plan. The SEIS evaluates potential environmental and traffic impacts of different development alternatives; the subsequent code work will determine density, design and infrastructure requirements that shape future growth.
