King, WA: Legacy SWDM pages explicitly point to the 2026 manual

King's legacy 2021/2024 manual page identifies the 2026 SWDM as current and notes construction-start conditions affecting older permitted projects.

Remote plan-based takeoff support; no local office, completed local project or site investigation is represented by this page. Cost, delivery schedule and deliverables depend on the agreed project scope.

What this changes in the bid review

Estimating interpretation: Do not reuse an older permitted design solely because it remains online. Resolve transition applicability and retain the accepted treatment detail and media specification with the takeoff.

Check the project documents

Mark each item after reviewing its supporting document.Record the governing SWDM version and project permit date.Confirm transition requirements using the construction-start status.Compare accepted bioretention details with specified media.

Clarification to request: Does this older permit need a standards update before construction starts?
