Auburn Way South (SR 164) Corridor & Safety Improvements – Dogwood St SE to Fir St SE (2 projects)

Client: City of Auburn

Role: Lead Roadway Engineer & Design Manager | CH2M

Dates: March 2012 to December 2015

This project improves access management, creates u-turns, upgrades transit stops and street lighting. It also widens Auburn Way South (SR 164) to accommodate turn lanes, pedestrians and bicycles. Sidewalks and pedestrian push buttons are being upgraded to meet current ADA standards including countdown pedestrian signals and audible pedestrian push buttons. Traffic signals are also being upgraded to improve both phasing and signal head visibility. Utility undergrounding and waterline improvements are being accomplished as part of this project as well. Stephanie’s work as the lead roadway engineer and design manager not only includes coordination of the design disciplines, but also leading the roadway including WSDOT requirements including Channelization Plans for Approval and Design Variance Documentation.

Windermere CSO Reduction

Client: City of Seattle – Seattle Public Utilities

Role: Lead Roadway Engineer | CH2M

Dates: February 2011 to February 2015

Located along Sand Point Way NE (SR 513), the Windermere CSO Control Project reduces overflows from the Windermere basin from approximately 14 per year to less than one per year. The project included siting and design of a 2.05-million gallon combined sewer overflow (CSO) control facilities to meet Washington State Department of Ecology’s regulatory requirements for the Windermere Basin by 2020.  As the lead roadway engineer, Stephanie’s work involved the reconstruction of both the Sand Point Way NE and NE 65th St roadways, including the site prep, paving, grading, channelization, signing, striping and ADA design. The initial design of this project was completed in 2012 as part of a GCCM delivery model, but post construction in 2015 Stephanie also completed an ADA maximum extent feasible report to document the deficiencies in the construction of the curb ramps with regards to meeting ADA guidelines.

M Street Grade Separation – Underpass

Client: City of Auburn

Role: Roadway Engineer | CH2M

Dates: August 2010 to June 2014

Stephanie served as the roadway design engineer for the M Street SE Underpass Project which created eliminated the at-grade crossing of the BNSF Stampede Pass Line at M Street SE by lowering the roadway to create an underpass. The project constructed two railroad bridges, roadway widening to accommodate up to five travel lanes, sidewalk, bicycle lanes, lighting, traffic signal, stormwater pump station and pond, and relocated utilities to accommodate the new roadway grades. This undercrossing improved safety and freight mobility. The creative roadway geometric design reduced impacts to properties while meeting ADA accessibility requirements. Stephanie was responsible for paving, signing, striping, typical sections, and demolition plans. She also performed interdisciplinary coordination, quantity take-offs, estimating, and specification editing. Throughout construction, Stephanie remained on-call to answer requests for information (RFIs).

Client: City of Redmond

Role: Lead Roadway Engineer | CH2M

Dates: May 2012 to November 2012

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.

RapidRide D Line

Client: King County Metro

Role: Roadway / Transit Engineer | CH2M

Dates: August 2011 to August 2012

Stephanie was the lead design engineer for the passenger facilities and transit improvements of this highly visible project connecting Ballard to downtown Seattle. Stephanie’s work included leading the civil engineering for more than twenty Metro bus zones throughout the D-Line corridor. Stephanie’s work includes upgrades for American with Disabilities Act (ADA) accessibility, paving, grading, signing, striping, and demolition plans.  Stephanie coordinated with property owners and business owners along the corridor to obtain approvals and discuss issues related to the proposed improvements. Her work also included coordinating with King County Metro as well as proactively coordinating multi-disciplinary issues across various departments within the City of Seattle including the pedestrian and bicycle group, Urban Forestry, Seattle Public Utilities, Seattle City Light, and Signal Design and Traffic, and Street Use.  Each of these bus zones were delivered independently of each other to accelerate the construction by Merlino Construction. To accelerate the construction Stephanie’s work also included designing the temporary traffic control plans as well as applying for and coordinated the street use permitting with the City of Seattle.

Sunset Area Planned Action EIS – Sunset Blvd (SR 900)

Client: City of Renton

Role: Lead Roadway Engineer | CH2M

Dates: July 2010 to May 2011

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.

Santa Clara – Alum Rock Bus Rapid Transit

Client: Santa Clara Valley Transportation Authority

Role: Civil Engineer | CH2M

Dates: July 2010 to February 2011

Stephanie served as the civil transportation design engineer for the preliminary plans and estimates for this Santa Clara VTA project. This complex public infrastructure project included 21 new stations, pedestrians walkways, mixed-use lanes, dedicated bus lanes, and median station configurations. The BRT design included build-outs for bus stops with shortened pedestrian crossings and raised platforms. The design applied the latest safety design innovations, using safety design concepts from street-running light projects. Station architecture included iconic branding, solar-powered station lighting, CCTV cameras, Real Time Information Systems (RTIS) and emergency telephones. The project also included a continuous fiber-optic communication system and transit signal priority. Stephanie’s project designs included median bus way designs along a major arterial including side-running and median BRT station designs in the City of San Jose. These design led to the construction of roadway improvements including ADA compliance and multimodal designs. Stephanie’s design work included preliminary station civil design and pavement delineation per the City of San Jose and Caltrans standards.

Seattle Urban Mobility Project – Project Feasibility Assessment

Client: City of Seattle (Department of Transportation)

Role: Roadway Engineer | CH2M

Dates: March 2008 – May 2008

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.
