Project Overview
Columbia Engineering Group provided civil engineering for Nomad Subdivision in Washougal, Washington. The project involved development of a 1.9-acre site for a single-family residence while also supporting seven private lots.
In addition, CEG designed a half-width public road improvement along one edge of the property. The civil scope also included utility easements for power, water, and sanitary sewer service, along with a low-maintenance stormwater system designed without HOA oversight requirements.
Site Development Approach
This project required coordinated civil infrastructure across both private lot development and public-facing improvements. Therefore, the design had to balance roadway access, utility service, and stormwater performance within a relatively compact site.
At the same time, the project emphasized long-term efficiency. As a result, CEG developed infrastructure that supports functionality while reducing ongoing maintenance demands.
Engineering Scope of Work
CEG delivered civil engineering for the subdivision and site infrastructure. Overall, the scope focused on access, utilities, stormwater management, and practical long-term performance.
🏘️ Subdivision Site Development
The project supported development of a 1.9-acre site for a single-family residence and seven private lots through coordinated civil infrastructure design.
🛣️ Public Road Improvement
CEG designed a half-width public road improvement along one edge of the property to support site access and frontage-related development needs.
💧 Utility Easements
The design incorporated a utility easement to provide power, water, and sanitary sewer service across the project site.
🌧️ Stormwater Design
CEG designed a low-maintenance stormwater system that does not require HOA oversight, helping support long-term efficiency for the subdivision.
✅ Coordinated Infrastructure Planning
The project brought together roadway, utility, lot, and stormwater improvements in one coordinated civil scope designed around functionality and long-term efficiency.
Project Outcome
Nomad Subdivision combined site development, utility planning, roadway improvements, and stormwater design on a 1.9-acre property in Washougal, WA. Through coordinated civil engineering, CEG helped support both a single-family residence and seven private lots with infrastructure designed for practical long-term use.
Just as importantly, the project incorporated a low-maintenance stormwater system that does not require HOA oversight. As a result, the development balances functionality with a more efficient long-term management approach.
What Made This Project Stand Out
The project supported a single-family residence and seven private lots on a 1.9-acre site through coordinated civil design.
CEG designed a half-width public road improvement along one edge of the property as part of the overall site development scope.
The civil design included a utility easement for power, water, and sanitary sewer service to support the subdivision layout.
The project included a stormwater system designed without HOA oversight requirements, supporting a more efficient long-term approach.
