Tumwater hearing examines 184‑lot Vista Views subdivision, wetlands mitigation, sewer and traffic plans

TUMWATER, Wash. — At a public hearing before Hearing Examiner Mark Scheifemeyer on Jan. 20, 2025, city staff and the applicant presented a proposal to subdivide roughly 54 acres near Black Lake into 184 single‑family lots and sought a city infrastructure exception that would permit roadway and utility work adjacent to on‑site wetlands.

The project, filed as application TUM‑24‑1446 and marketed as Vista Views at Black Lake, proposes three phases of development and construction of a new sanitary sewer pump station and at least a mile of sewer and force main to extend city service into the area. City staff summarized technical review and recommended approval “of the phased preliminary plat and infrastructure exception with the attached conditions,” the staff planner testified.

Why it matters: The application asks the city to allow elimination of two small wetlands on the site under Tumwater’s small‑wetland standards while committing to substantial wetland compensation and buffer enhancement elsewhere on the property. The project would also add an estimated 1,700–1,800 daily vehicle trips, require traffic mitigation at a failing intersection, and extend sewer infrastructure that the applicant says will serve a broader area around Black Lake.

Project and staff recommendation City staff described the site at 3717 49th Ave SW and 3825 58th Lane SW as mostly flat former pasture that drains toward a larger Category 2 wetland in the northwest of the property (wetland A) and two much smaller Category 4 wetlands in the southern portion (wetlands B and C). The applicant proposes 103 lots in phase 1, 47 in phase 2 and 34 in phase 3. The staff report includes conditions for sidewalks, stormwater, tree replacement, and wetland mitigation and notes an infrastructure exception to allow public‑standard improvements adjacent to critical area buffers along 49th Avenue.

“We recommend approval of the phased preliminary plat and infrastructure exception with the attached conditions,” city staff said during the hearing, summarizing their review of the application materials, technical reports and agency comments.
