The City of Bellevue is conducting a replacement study for the aging Newport Shores Sewer Pump and Lift Stations, including the Force Main that connects to nearby King County regional facilities. The findings will help identify various alternatives for improving these systems within the Newport Shores community. The goal is to identify and select a long-term, high-level service solution that minimizes disruption for homeowners while ensuring reliable sewer management.
Why This Project is Needed
The sewer system servicing the Newport Shores and surrounding community was constructed in the early 1960s with minor renovations in the late 1980s. Now over 60 years old, the facilities are reaching the end of their expected service life. Added strain has been placed on the system due to poor soil and the likelihood of excess water seeping into the sewer through small cracks. The City is evaluating rehabilitation and replacement needs to prevent significant sewer disruption from potential failure risks and ensure a high service level for the next generation. This will improve the sewer system's reliability, increase capacity, and enhance operational efficiency.
Project Location
- Newport Shores Pump Station – Skagit Key (Cul-de-Sac)
- Newport Shores Lift Station – Cascade Key (West of Crescent Key)
- Newport Shores Force Main – Skagit Key to Newport Key to Lake Washington Blvd SE to Coal Creek Parkway to 119th Ave SE
- Gravity Sewer Canal Crossing - Cascade Key (Cul-de-Sac to Skagit Key)
Project Funding
The project is funded through City resources identified in the Capital Improvement Plan (CIP) Budget for Sewer Pump Station and Force Main Improvements.
Project Approach
The project will be completed in three phases:
- Phase 1: Analysis – This phase is currently underway and includes the identification of multiple alternatives to replace and rehabilitate the Newport sewer system.
- Phase 2: Design – Once a preferred alternative is selected, design and permitting are expected to proceed. This may include designing one or multiple projects depending on the complexity of the preferred alternative.
- Phase 3: Construction – The final phase will involve replacing one or more components of the Newport Shores sewer system while minimizing disruption to the community.
Project Solutions (Alternatives)
Due to the complexity of the Newport Shores sewer system, alternatives are still being evaluated and may include the relocation, replacement, or rehabilitation of the facilities. Ongoing updates will be provided.
Project Timeline
- Analysis: Q3 2024 - Q4 2025
- Design and Permitting: Q1 2026 - Q4 2027
- Construction: To Be Determined
Opportunities for Public Input
Project information flyers are being distributed to the Newport Shores community in early 2025. A community open house will be scheduled for Q3 2025 to provide a project update on alternatives being considered and answer any questions.
