Cascadia Civil · Oregon & Washington
Technical depth.
Practical design.
Land development, municipal infrastructure, water resources, structural engineering, and the permitting that ties them together.
The practice
Engineering that clears review and gets built.
Cascadia Civil delivers civil, water resources, and structural engineering across Oregon and Southwest Washington. Design, modeling, and permitting run as one scope, so what reaches an agency reviewer is complete the first time.
We work with private developers, builders, public agencies, and restoration partners, from first feasibility questions through construction.
