Project Status: Approved
This project has been reviewed and approved by the City’s Hearing Examiner, a private, non-partisan land use attorney. 

Construction is anticipated to begin in the summer 2023.

Permit Application Review: The project included both a Site Plan Entitlement and Conditional Use Permit, which means this project has been through full project review and processed per the Redmond Zoning Code criteria. All permit requirements were met. 

Environmental Review: This project completed a full environmental review. The City of Kirkland was the lead agency working in partnership with the City of Redmond, per the State Environmental Policy Act (SEPA), which states that the city with the majority of the project takes the lead on environmental review. Environmental impacts disclosed were determined to be non-significant. 

The project exceeds the City’s 35% tree retention requirements, retaining 60% of the significant trees within the project area. All removed trees will be replaced per the City’s tree regulations

Minimal impacts to streams and wetlands will be mitigated per city regulations. PSE will replace six culverts, including three which are fish passable, in the project area.
