The 2019 voter-approved Library Levy provided $13.8 million in funding to seismically retrofit the historic Green Lake, University and Columbia branches.
A survey identified the three unreinforced Carnegie buildings as high-risk for damage and loss of life in the event of a major earthquake. The 2016 survey was conducted by the city Department of Construction and Inspection, which advised these buildings be retrofitted in the next seven years.
The seismic upgrade to each of these landmarked buildings is estimated to take approximately 18 months to complete. The buildings will be closed during construction.
Detailed information on each project, including building closure dates and alternative services, will be shared as it becomes available.
The Seattle Public Library’s Green Lake Branch, one of the Library’s historic Carnegie buildings, reopened on October 28, 2024. The branch temporarily closed beginning February 1, 2023 for major renovations, including a seismic retrofit and the installation of an electric HVAC system and accessible elevator, and other interior improvements.
This project, funded by the 2019 Library Levy, presented a unique opportunity to make the Green Lake Branch safer, greener, and better able to meet the needs of the community while preserving its important legacy.
The improvements and renovations to the Green Lake Branch included:
The Seattle Public Library’s University Branch has temporarily closed from Wednesday, January 29, until late 2026 for a seismic retrofit and other major renovations, including the installation of an electric HVAC system, an elevator, additional restrooms, study rooms, and a dedicated multipurpose room.
Project details, plans and illustrations may be found in the University Branch Presentation Boards and Architectural Plans. The unique historical and cultural legacy of the University Branch will be protected and preserved throughout the project.
This project is made possible by funding from the 2019 Library Levy. Additional funding for this project has been provided by a Congressional procurement secured by U.S. Rep. Pramila Jayapal and by grants from FEMA’s Hazard Mitigation Program and the Washington State Department of Commerce.
Project Scope:
Seismic Retrofit
The University Branch will undergo a seismic retrofit to protect patrons, staff and the building during an earthquake.
HVAC Installation
The current gas-powered furnace will be replaced with a modern, electric HVAC system, providing air conditioning and improved ventilation while reducing carbon emissions.
Accessibility Improvements
Access to the branch will be improved with new accessible ramps and paths from perimeter sidewalks to branch entrances, new accessible entrances at the southwest corner and north side of the branch, new accessible parking spaces, new accessible restrooms on both floors and the installation of branch elevator.
Interior Renovations
The branch interior will be reconfigured with the addition of two new study rooms, a dedicated music room, a relocated and renovated meeting room and additional public restrooms. New and improved lighting, shelving, carpets and furniture will also be installed in the branch.
Exterior Renovations
The branch exterior will be repaired and repainted. Historic design elements, including exterior windows and stucco will be restored and weatherproofed. The existing clay tile roof will be retained with minor repairs.
Sustainability
The renovated branch will meet the City of Seattle’s goals for environmentally responsible design and will be LEED Gold Certified. Along with other energy conservation improvements, the branch will be outfitted with solar panels on the roof and capacity for future EV charging stations on the parking lot.
In recent months, the western rear wall of the University Branch, which was constructed of unreinforced masonry, has been removed. Over the next few months, a reinforced concrete shear wall with a new foundation will be erected in its place. Two more shear walls and a structural archway of reinforced concrete will also be erected, together comprising the basis of the seismic retrofit.
The historical architectural features of the branch exterior will be preserved and, when complete, the new western rear wall will look just like the old one. The large, original windows have been removed and safely stored, and will be reinstalled in the new wall.
We are currently building a foundation for an addition to the northwest corner of the branch where new study rooms will be built. To protect an exceptional tree located nearby, this foundation will be created using beams supported by vertical rods driven into the ground, rather than poured concrete. The new study rooms will be located on the main floor, adjacent to the landing for the new branch elevator.
At the southwest corner of the branch, we are preparing to add a vestibule to the branch, serving as a new ADA-accessible entryway. This entry will be accessible from new pathways in the front and south side of the branch and also from the parking lot, which will be regraded to eliminate its challenging slope.
Inside the branch, we are preparing to install large glass walls along the children’s area and reading room, bringing in more light and improving sightlines for patrons. Along with new lighting and shelving, new carpets and furniture, a new central information desk and other amenities, these improvements will help create an open, modern feel to the branch while preserving its historical architectural and design elements.
Stay tuned for the next update coming later this fall on the continued progress of renovations at the University Branch. If you have questions about the project, please reach out to us online at Ask Us.
With funding from the 2019 Library Levy, the Columbia Branch will undergo major renovations projected to begin late 2026 or early 2027. The work will include a seismic retrofit, the installation of an electric HVAC system, extensive accessibility improvements and interior modernization. The unique historical and cultural legacy of the Columbia Branch will be protected and preserved throughout the project. We expect the Columbia Branch project to be similar in scope to the Green Lake Branch project that was successfully completed in October 2024.
Early project scope and design work for the Columbia Branch project is complete. In June 2024, we received funding for the installation of a modern HVAC system at five Library locations, including the Columbia Branch, through FEMA’s Hazard Mitigation Grant Program. We do not yet have an anticipated start date for construction.
