Stephanie served as the roadway design lead for the 160th Avenue NE Extension Project. Her work included conceptual roadway design alternative development, evaluation, selection, and budget level cost estimates to improve the safety of all modes of travel, accommodate the increased need for additional vehicle capacity, and provides essential arterial linkages outside of Redmond’s downtown core. These roadway alternatives balanced the needs of future vehicular traffic along with the needs of pedestrians, bicycles, and equestrians; minimized the disturbance to the environment and properties; and defined a solution that is practical and economically feasible for the City.
Stephanie was the lead roadway design engineer for the planned action environmental impact statement and drainage master plan to support redevelopment of an underutilized portion of the City of Renton, including redevelopment of a public housing site, improvements to SR 900, and implementation of a regional stormwater management plan. The master plan included development of green streets and incorporating green stormwater infrastructure. Her work included multiple design and alignment alternatives and cross sections to meet the needs of the community. The designs were aimed being context sensitive to reduce the need for right of way acquisitions and maximizing the use of the existing City owned property while providing multimodal access for the community.

Stephanie was a roadway design engineer for the feasibility design for multiple urban mobility preliminary designs for the City of Seattle. Stephanie developed multiple design alternatives, reports and exhibits for SDOT. This project was aimed at the development and evaluation of alternative strategies to address the removal of the Alaskan Way Viaduct along the Seattle Waterfront and provided technical support regarding surface street, pedestrian, bicycle and bus transit infrastructure solutions. Based on the eight design concepts for the removal of AWV, the project focused on the design and cost estimates for the 60+ local road improvements. Examples of surface street improvements included were Lander Street Grade Separation, East Marginal Way Grade Separation and a Marion Street Pedestrian bridge over I-5. Stephanie also worked on developing the methodology for generating the concept level cost estimates, illustrating the concepts, creating engineering drawings, and other data to outline implementation issues, design challenges, and risks with each alternative.
