Seaside Elementary, Middle, and High Schools

KPFF provided civil and structural engineering design services and surveying for a new three-story, 140,000 SF combined Middle School and High School to accommodate 900 students including associated vehicle circulation, parking and play fields. The project included an addition and seismic upgrade to the adjacent Seaside Heights Elementary School and served to replace seismically vulnerable facilities located in the tsunami zone with a consolidated and resilient campus for all Seaside students. Located on a hill, the Middle and High school has unobstructed views to the west of the Pacific Ocean and Tillamook Head and is designed as an evacuation point above the tsunami inundation zone.

Work on the 50-acre site required significant earth-moving activities to gain access to a suitable building area and resulted in extensive utility design, permitting solutions, and close coordination with the City of Seaside. ​​​​​​​Design for the project involved stormwater management through an extended dry detention facility, which provided protection to nearby salmon-bearing streams. Wetland mitigation and enhancement areas were designed to meet USACOE and DSL requirements. An 18” public water main was constructed through the site to connect the new school to a future municipal water storage reservoir and booster pump.

During design KPFF created Civil CGI fly-over animations and site renderings to aid our team in visualizing traffic flow, utility locations, and the overall final project scope and layout.

For the Seaside Heights Elementary seismic upgrade, the structural engineering team assisted Seaside School District with the application for a TAP Grant to perform a seismic assessment, then provided the seismic assessment and acted as prime design professional in completing the Seismic Rehabilitation Grant Program (SRGP) application. Upon receiving funding, KPFF worked with the architects and mechanical, electrical, and plumbing consultants for the design, permitting and construction of the seismic upgrade, which consisted of adding wood framed shear walls, additional collectors and blocking in the roof diaphragm, and additional holdowns with enlarged concrete footings to resist overturning. Structural engineering was also provided for a covered play structure and for the foundations and interior remodel of a pre-engineered metal gymnasium building.
