For over ten years, SCJ has led planning, engineering, and NEPA Environmental Assessment (EA) work for a comprehensive multimodal alternatives analysis and NEPA EA on an eight-mile segment of I-5 near JBLM. The analysis evaluated solutions to reduce congestion, improve freight and passenger movement, and enhance community connectivity. The aggressive schedule required a creative approach to managing a broad and open stakeholder process. SCJ collaborated with 14 agency partners, engaging over 60 individuals through continuous communication with agencies, the public, and JBLM. As a key priority project in Washington, it emphasized least-cost planning and practical design, with an innovative integration of transportation and environmental planning. Approval of the NEPA EA advanced the project toward design-build delivery and, through a collaborative process, achieved full endorsement and over 40% in cost savings from the original planning estimate.
