Heidi Post, the neighborhood association’s land-use chair, told a July information session that several road segments serving a proposed 174th Street subdivision exceed the county’s congestion threshold and that the county’s hearing examiner nevertheless approved the project.
"There were three segments ... the worst one is 133% full," Post said, summarizing traffic-engineer findings showing multiple roadway segments above the county’s 0.9 capacity threshold. She said the county code and the association’s 2011 concurrency manual require developments be denied or delayed if public facilities are not adequate at occupancy.
Post described how the code measures capacity and intersection delay, how county staff add "in-process" developments and growth assumptions into projections, and why she thinks some in-process projects were not counted in the 174th Street review. "So that's what the code says should be done," she told attendees while walking through the manual's sections and the county's traffic-count method.
Post also said staff and the hearing examiner treated several projects and a planned state-funded interchange as capacity credit on the county’s six‑year TIP — an approach she said the 2011 concurrency manual does not authorize. Post said a public-records review showed county staff and the deputy county manager worked on messaging to support the examiner’s decision and that she found a reference in documents to use of an AI tool to draft messaging: "our deputy county manager using Copilot to figure out how to override the code," Post said.
Residents responded with concern about future traffic and safety. Post gave counts she said are drawn from her review of approvals since urban holding was lifted: "3,300 housing units ... 924 in the pipeline, so about 4,200" and "PM peak hour trips, 4,080 approved." She warned that when trip-generation assumptions treat new attached housing or multifamily units as lower-trip generators, road impacts and funding needs can be underestimated.
Post said she is pursuing an appeal of the hearing‑examiner approval. She reminded attendees of the administrative deadline and said an appeal must be filed within about 21 days; she estimated legal costs of roughly $30,000–$40,000 and said a land-use attorney who is already familiar with the record has agreed to take the case. "I'm working on setting [a GoFundMe] up," she said.
Post and other residents urged continued community engagement on the comp plan, traffic studies and TIP funding. She urged attendees to monitor an August 19 work session and other upcoming council and planning-commission meetings where concurrency and funding issues will be discussed.
The neighborhood association said it will share maps and a detailed table of the approved and in-process projects with county council and urged neighbors to sign up for updates and the planned fundraising effort. The hearing-examiner decision stands for now while organizers pursue an administrative appeal.
