The project features a duplex conversion alongside two new fourplex structures served by consolidated access drive, pedestrian routes, and full utility infrastructure. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/3b9a9fba-2a75-465f-a1c0-33179b44e050/155+37th+Project+Aerial.png Projects 37th Avenue Partition — Salem, Oregon This infill land division project involved partitioning a 0.43-acre parcel in an established Salem neighborhood to create a buildable lot for two new duplex residences while retaining an existing single-family home. Successful entitlement required two Class II Land Use Adjustments, and navigating significant stormwater engineering challenges within a highly constrained urban site. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/bf6dc1d2-92b9-4f72-bcb8-9255def9649b/Neff+Purcel+1.jpeg Projects Neff Road & Purcell Boulevard Improvements - Bend, Oregon The Neff Road and Purcell Boulevard Improvements Project was a high-priority, ~$10 million City of Bend capital improvement project completed in late 2023. Stormwater design for this project was led by a Cascadia Civil Principal Engineer during tenure with a previous firm. The design required multi-agency coordination and incorporated retrofit stormwater infrastructure, including drywells, to meet water quality requirements within the constraints of the existing urban corridor. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/ca5ceacc-e0fc-49bf-b2a3-de72b6263672/Lepman+1.png Projects Chicago Townhomes - Albany, Oregon Cascadia Civil provided structural engineering services for this 8-unit commercial multifamily development in Albany, Oregon. The wood-framed project required coordinated structural design to meet the demands of a multifamily occupancy while supporting the owner's development goals. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/21ceaca4-80f3-4f42-8ffb-8c313c825940/Klobas+Isometric.png Projects NE 76th Ave Residence - Portland, Oregon Cascadia Civil provided structural engineering services for this modern single-family home featuring an open-concept ground floor, a second story with complex framing geometry, and a habitable roof space. The primary structural challenge was resolving the load path from the upper levels through a largely open lower floor — minimizing visible structure while maintaining the clean aesthetic the design demanded. The result is a home that balances architectural ambition with a sound, efficient structural system. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/f731fe8d-1f17-414a-8617-d515870ddd67/Foodcarts+CAD2.png Projects First Street Food Carts - Scappoose, Oregon Cascadia Civil provided full civil design services for a new 8–10 space food cart pod in downtown Scappoose, including site grading, paving, utility infrastructure, and ADA-compliant accessibility improvements. The parking layout was optimized to maximize stall count and circulation efficiency while maintaining compliance with federal accessibility standards. Stormwater management was achieved through a compact infiltration trench system providing code-required detention and water quality treatment with minimal surface impact and a clean aesthetic fit for a pedestrian-oriented commercial development. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/0fa7e54a-4633-406f-860d-cf8f2ab3f1cd/Divine+Grounds+No+Rise.png Projects FEMA No-Rise Analysis - Seaside, Oregon Cascadia Civil LLC delivered floodway permitting for a new commercial structure in the heart of Seaside's Necanicum River regulatory floodway. Using HEC-RAS hydraulic modeling and compensatory flood storage design, we secured a No-Rise certification for Clatsop County, enabling the project to move forward without increasing flood risk to the surrounding community. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/cc72c73c-d860-4b50-b4dd-2335f453a86a/Sexton+1.jpg Projects Sexton Mountain Pump Station - Beaverton, Oregon Served as the Engineer of Record for site civil and stormwater design on the renovation of the Sexton Mountain Pump Station — a primary pump station in Beaverton's drinking water system. Scope of work included on-site grading, paving, utility design, and stormwater management facilities to support the modernized station. Completed while working with a previous firm https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/71c1854a-76f7-4556-a4fb-f84abd8bd4a6/Container+ADU.png Projects Shipping Container ADU - Portland, Oregon Cascadia Civil provided structural engineering services for a multi-container ADU in Southeast Portland, delivering a stamped structural plan set and calculation package for building permit submittal through Portland BDS. The scope included evaluation of container modifications, opening reinforcement, foundation connections, and roof attachments. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/1d6a3a93-1fb6-4fad-bdaf-6e3ba56c0192/Beaverton+Sewer.png Projects Western Avenue Sanitary Sewer System Analysis — Beaverton OR Evaluated the capacity impacts of rerouting sanitary sewer flows near SW 5th Street and SW Western Avenue in Beaverton, Oregon, where a proposed regional water transmission line conflicted with an aging 10-inch sewer main. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/d597f264-f5e6-42d7-bcf2-7ca0424926b5/Rockaway+2.jpg Projects Pacific View Drive Renovation - Rockaway Beach, Oregon Cascadia Civil provided structural engineering services for a full studs-down remodel of a distressed coastal property in Rockaway Beach, Oregon. Working closely with the architect and owner, we developed lateral and seismic systems to address the challenges of non-conventional existing construction while achieving the open, expressive spaces envisioned for the project. Custom connection design was integral to resolving the unique load paths and bringing the structural intent to life within the architectural framework. https://images.squarespace-cdn.com/content/v1/67ccca40f555350c2247aad7/5d7dae99-80aa-4649-abb9-b93ab8ec55bb/Chinook+Village.png Projects RV Park — Warrenton, Oregon Designed civil infrastructure for a 100+ space RV park development along the Skipanon River, including roadway and pad pavement systems, water distribution, sewer, and stormwater management. The project presented significant engineering challenges due to poor-drainage organic floodplain soils, requiring purpose-built solutions such as enhanced pavement sections and distributed lift station sewer systems. Every design element was developed in compliance with a complex multi-agency regulatory framework spanning local zoning, Oregon DEQ water quality standards, and federal wetland oversight.
