The SEA Environmental / Planning Group is comprised of seasoned professionals with extensive experience in Transportation Project Planning, Project Management, Environmental Compliance, Public Involvement, and Community Studies. Our team has authored and managed both NEPA and SEPA projects, ranging from complex federal Environmental Impact Statements to straight-forward state Minimum Criteria Determination Checklists. Along with project development documentation, we specialize in Community Impact Analysis, Indirect and Cumulative Effects Determinations, and Land Use Screening Analysis. We have planning experience that covers a range of transportation modes from small to large roadway improvements, railroad upgrades and crossing closures, transit feasibility and ridership surveys, pedestrian and bicycle accommodations, and airport enhancements. Our collaborative and attentive approach to project planning enables us to identify potential problems and recommend solutions early in the project planning process, allowing project schedules to be maintained.
