New Renton High School & Site Expansion

Renton High School continues to be a safe, welcoming, and exceptional place for learning and student success. However, there are several reasons to expand the Renton High School campus for our students, families, and staff, to provide a modern learning environment and athletic opportunities for all our high school students.

Restrictions to build on the current Renton High site mean we’ve been unable to make equitable improvements compared to other district high schools. These restrictions leave us unable to provide some of the same amenities and facilities for Renton High students that our other high schools offer. With funding approved by voters in the November 2022 election, we can move forward with a comprehensive plan to expand the footprint of the current school and construct a new campus to improve education for Renton High School students for many decades to come. 

Important considerations for expanding the Renton High School campus:

Built on Small Parcel of Land

While most modern high schools are built on 30-40 acres to include suitable learning spaces along with sports and athletics fields, Renton High School is built on only 23.7 acres with a portion being restricted or limited by Renton Airport and FAA restrictions. In comparison, Hazen High School is built on 33.3 acres and Lindbergh High School is built on 37.2 acres.

The new Renton High School will be a three-story, 350,000-square-foot comprehensive high school, on an expanded 33.3-acre site, with classroom capacity for 1,600 students. The school is projected to open in the fall of 2029.

Built Adjacent to Renton Municipal Airport

Improvements for the current layout of Renton High School are restricted as it is adjacent to Renton Municipal Airport and subject to the restrictions of approach and departure airspace requirements as well as the currently established ground level Runway Protection Zone (RPZ). Airspace restrictions prohibit adding lighting to the existing fields on the west side of the property and make it difficult to add height to the existing school for additional learning space. Thanks to voter support, we can purchase property and land adjacent to the school and construct a new campus away from the airport restricted area.

The measure approved by voters to build the new Renton High campus included purchasing land for the project. For more than 2½ years, the district worked with property managers and brokers, the City of Renton, and public and private landowners, examining more than 10 potential properties within district boundaries for a possible new location for Renton High School. While initially some seemed like the right fit for a new school campus, further examination revealed shortcomings not conducive to a new school location:

• Too many environmentally critical areas (steep slopes, wetlands, streams, etc.).
• Major arterial roads and/or railroads divided sites.
• Properties too small for a comprehensive high school program.
• Environmental remediation concerns.
• Distance from student homes too great for reasonable transportation access.
• Restrictive deed covenants.
• Abundance of existing structures requiring specialized demolition and removal.

Due to these restrictions, In May, 2023, the Renton School Board approved the plan to expand the footprint of the current Renton High School location and purchase property to build the new campus at the school's current location.

Our plan is to build a new high school building and athletic fields on the expanded site, while retaining the original 1929 historic façade of the Renton High School building and the IKEA Performing Arts Center. The current project area expands the current Renton High School footprint, adding nearly 10 acres and bringing the new site to 33.3 acres. The projected date of opening is the fall of 2029.

Timeline

Building a New Renton High Campus as Promised

Holding true to the promises we made and were approved by voters, we’re building a three-story comprehensive high school for Renton High School students, staff, and families on the current Renton High site. The new school campus includes core classrooms and other learning environments for Career and Technical Education, College-level (International Baccalaureate) classes, art, science, elective classes, health services spaces, community spaces, library, gyms, cafeteria, commons, special services and support spaces, and more. The new campus also includes a lighted athletic baseball/softball field and a practice football/soccer field in northwest corner.

The areas that are west of the current Renton High School building are very limited with regards to new construction or improvements, due to the Renton Municipal Airport runway protection zone.  The only opportunities for new construction in that area include minor improvements to existing field and parking lots to the south with lower height light poles.

Work with Renton High Staff, Students, and Community on New School Design

In the spring of 2023, BRIC Architecture, Inc. was hired to provide design services for the Renton High School project. Through the summer and fall of 2023, BRIC and the district's Capital Planning & Construction staff focused on a community engagement “Listening and Learning” process to hear from as many voices as possible within the Renton High School and Renton School District community. The group met with many families, students, and community members, and continue to receive valuable input to ensure we design a facility that meets student learning and community needs.

Purchasing Property in New Build Zone

The project area involved purchasing 42 parcels, including 32 homes and eight commercial sites. We will also relocate the district's warehouse/nutrition services building currently located on the Renton High campus on South Tobin Street. We have finalized the purchase of property within the identified new school project area, which included providing relocation assistance and reimbursements for property owners displaced by this project. We are finalizing demolition of existing structures of purchased properties.

Renton School District is working to ensure we careful to archaeology and cultural resources on the site of the new high school. We have retained Historical Research Associates, Inc. (HRA) to conduct research, investigation, and monitoring on the project area throughout the duration of design and construction.

• Archaeology work plan developed and distributed to Tribal representatives in June 2024.
• After review, field investigations were conducted at available properties and Tribes are invited to observe all field investigations.
• An archaeological report was prepared and submitted to Department of Archaeology & Historic Preservation and Tribes for review in April 2025 (DAHP Project Number 2024-05-03846)
