Program and Construction Management

Hood Canal Bridge Replacement Management Support Organization – WA
Parametrix is providing a broad range of project and construction management services for the Hood Canal Bridge replacement project, a decade-long project to replace aging components of the 40-year-old bridge, a 13,000-foot-long floating marine structure. Our assignment began shortly after the State of Washington decided to terminate construction of a bridge component construction facility in Port Angeles due to discovery of a historic Native American village at the site. This decision created the need for major changes in the construction approach, including identification of alternative sites to construct and outfit pontoons and anchors, and reorganizing the project team. We guided WSDOT through the development of a new and improved teaming approach to manage the project. Our approach creates a blended WSDOT and consultant team, uses an interactive staffing projection model, implements performance standards, suggests more efficient ways to use WSDOT staff resources, and promotes new ways of doing business that can be transferred to other projects.

SR 520 Bridge Replacement and HOV Corridor Program GEC – King County, WA
This project addresses critical infrastructure replacement and mobility needs for the SR 520 corridor that spans Lake Washington and connects Seattle and east King County. As a member of the General Engineering Consultant (GEC) team and under individual on-call engineering management services task orders, Parametrix is providing key staff in various strategic positions for the delivery of the SR 520 Bridge Replacement and HOV Corridor Program. The GEC team is charged with the advancement of the environmental strategy and engineering design overlapping with the completion of the SR 520 Supplemental Draft and Final EIS documents. Based on the Governor’s selection of the 6-lane alternative (consisting of 2 general purpose and 1 HOV/transit lane in each direction), the GEC is focused upon advanced design and strategic project delivery of the storm and seismically vulnerable structures within the SR 520 corridor. In addition, the GEC is directly responsible for site selection, alternatives analysis and environmental clearance of an environmentally controversial facility to fabricate up to 55 concrete pontoons for the Evergreen Point Floating Bridge across Lake Washington. Assuming completion of the Final EIS and acquisition of a Record of Decision, construction is estimated to begin as early as 2011.

Idaho Transportation Department Rest Area Program – ID
Faced with a resolution to deliver 10 new rest areas and rehabilitate 22 more rest areas across the state, ITD needed a new approach to project delivery. Parametrix worked with ITD to provide program management services including system planning, schematic design and environmental compliance, and design and construction oversight using independent consultant and construction services contracts. More than just restrooms, the rest areas are intended to showcase the natural beauty and cultural heritage of Idaho's diverse regions. Some unique aspects of the program included:

Construction services include contractor oversight, inspection, railroad coordination, and document control for federal funding.

Transportation Planning and Traffic Engineering

Newburg-Dundee Transportation Improvement Project – OR
The Newberg-Dundee transportation improvement project study was a collaboration between ODOT, Yamhill County, and the cities of Newberg, Dundee, and Dayton intended to resolve congestion on Oregon 99W. Several multi-modal alternatives were evaluated, but the biggest contributor to congestion relief will be an 11-mile bypass with four interchanges. Parametrix is preparing a tiered-location EIS to establish a bypass corridor, including consideration of eight corridor-level build alternatives. We are also developing plans for transportation system management, travel demand management, and IT.

Lake Hazel Road Extension/Gowen Road Relocation Alignment Study – Boise, ID
As part of an effort to accommodate the Boise Airport expansion, Parametrix worked with ITD to conduct an alignment study to locate a new arterial connection from the east end of Lake Hazel Road to I-84. This project will also allow the Boise Airport to expand south across Gowen Road without compromising transportation mobility. This project includes design and evaluation of more than 12 miles of new and realigned roadways, intersection design, traffic studies, bridge engineering, floodplain analyses, storm drain concept designs, public involvement, and environmental services.

Rhodes Lake Corridor Study and EIS – Pierce County, WA
This project will increase east-west transportation capacity between SR 162 and the rapidly growing plateau south of Bonney Lake. Parametrix is completing a feasibility study and preparing documentation of the environmental impacts of a new corridor. We have completed traffic projections, alternatives development and screening, and an extensive public outreach program. A key element of the study is evaluating the feasibility of constructing a new bridge crossing of the Puyallup River versus widening one of the existing structures.

Federal Way City Center Access Study – Federal Way, WA
Parametrix is completing an environmental assessment, interchange justification report, and preliminary design plans for the City Center Access Study Phase 2. The project involves a modification to the existing highly congested S 320th Street interchange to include new ramps at either S 312th Street or S 324th Street. The new interchange is critical for the City to achieve its ambitious plan for higher density residential, office, and retail in their central core area. Major environmental issues include Section 4(f) impacts to Steel Lake Park, possible environmental justice impacts to several residential areas, and impacts to a Sphangum Bog, a protected plant species.

Puget Sound Regional Transportation Plan Update – WA
Parametrix is providing transportation planning services including completing an EIS to update the Destination 2030 plan completed in 2001. Transportation 2040 will update the comprehensive, long-range, multimodal plan which serves as both the region's Metropolitan Transportation Plan for federal planning purposes and the Regional Transportation Plan under state law. The plan will include investments in state and interstate highways, city and county roads, high-capacity regional and local transit, ferries, non-motorized facilities, freight mobility, aviation, and a range of programs focused on preserving and managing the system and improving efficiency. Transportation 2040 will focus on four categories of improvements and programs: demand strategies, system management, tolling and pricing, and strategic expansion. The Transportation 2040 EIS will focus on the most compelling issues facing the region including congestion and mobility, energy, and the emerging issue of climate change. The plan update will also address tolling and congestion pricing programs, investments in transit, system and demand management measures, transportation funding, and investment prioritization. The EIS will cover a broad range of topics, but will focus on the key issues of air quality, water quality (particularly protecting the health of Puget Sound), and climate change.

Environmental Services

I-5 Columbia River Crossing – OR and WA
The Washington and Oregon Departments of Transportation, along with local government project sponsors, are working with a team of consultants to resolve congestion and safety problems in the five-mile stretch of the I-5 corridor between SR 500 in Vancouver and Columbia Boulevard in Portland. As part of the consultant team, Parametrix is leading the environmental work, which is subject to a complex set of regulations on the federal, state (Washington and Oregon), city (Vancouver and Portland), and county (Clark and Multnomah) levels. This could require permits or approvals from at least twelve different federal and state regulators. All of these agencies, as well as the two state transportation agencies sponsoring the project, and the Federal Transit Administration and Federal Highway Administration that may provide funding, have signed the Interstate Collaborative Environmental Process (InterCEP) Agreement. This formal commitment to collaboration by multiple state and federal agencies is a rare and promising signal that this project can proceed quickly and efficiently toward a solution.

Alaskan Way Viaduct and Seawall Replacement – Seattle, WA
The Alaska Way Viaduct (AWV) project is one of the largest transportation design projects under consideration on the West Coast today. Parametrix was part of a multi-consultant team that is evaluating alternatives and will design a new AWV through the heart of Seattle’s waterfront district. AWV is a critical component in Seattle’s transportation infrastructure and it, along with an adjacent Seawall, are both nearing the end of their useful lives. Improvements are critical to protect public safety and maintain the transportation corridor. Parametrix is providing a variety of engineering and environmental services on the project including all environmental documentation and project permitting. This includes a complete NEPA/SEPA EIS and all necessary federal, state and local permits to construct the project. Project construction is expected to take 7 to 10 years, with a project budget well into in the billions of dollars. In addition to environmental documentation, Parametrix is providing support to traffic planning studies, hazardous materials investigations (Phase I and II environmental site assessments), stormwater management plans, water quality assessments, sediment quality assessments, endangered species (ESA) evaluations and Biological Opinions, Section 4(f) analysis, visual quality, parks and recreation, public services and utilities, and general CAD and GIS support.

US 20/26 Corridor Preservation Study – Ada and Canyon Counties, ID
Parametrix is leading the corridor study for 16 miles of US 20/26 west of Boise Idaho. Planned growth throughout this corridor has led COMPASS and ITD to plan for right-of-way preservation and access control in order to handle future traffic needs. The study will include roadway, bridge, drainage, and intersection design. Public involvement, and consideration of transit and ITS will also be key components of this project. In addition to preparing a corridor plan and environmental assessment, the Parametrix team will prepare preliminary design and right-of-way plans to help the associated jurisdictions plan for future development.

Trans-Lake Washington Study and SR 520 Bridge Replacement – King County, WA
Parametrix was the lead consultant for a Transportation Commission-mandated study of mobility across and around Lake Washington, in the Seattle metropolitan area of King County. The project involved the analysis of 14 miles of SR 520, 21 miles of I-90, and 15 miles of SR 522, in addition to a number of intersecting arterial roadways and new roadway alignments. Parametrix has continued to be the lead consultant for subsequent phases of the project, including the preliminary engineering and NEPA/SEPA EIS stages. A variety of alignment, profile, and structural options have been developed, including new bridge and floating structures, submerged tubes, and tunnels with major interchange modifications at 12 different locations along I-5, I-405, and local arterials. In all, over 50 different interchange and alignment alternatives were designed to the applicable level of detail and standards for preliminary plans under WSDOT plan preparation guidelines. The project included substantial community and interagency involvement and an innovative program to develop integrated approaches to address transportation, community connection, visual, and environmental impacts of the corridor.

ODOT Statewide Bridge Assessment, Repair, and Replacement – OR
Faced with hundreds of weakened and cracked bridges, ODOT embarked on a 10-year, $3-billion strategy for repair and replacement of 400 bridges. ODOT and Parametrix collaborated with nearly a dozen regulatory agencies to streamline environmental processes, speed delivery of over 350 new or repaired bridges, decrease costs, and provide greater benefits to surrounding communities while saving taxpayers an estimated $50 million. This effort earned a national environmental excellence award from the Federal Highway Administration (FHWA). A shared philosophy known as Xtreme Collaboration enabled ODOT and Parametrix to efficiently and cost-effectively work with federal and state agencies. The results of this collaboration are:

NEPA documented categorical exclusions for over 350 bridges under FHWA
Field work and data collection to document conditions and estimate potential impacts associated with repair or replacement of over 350 bridges
Environmental baseline reports for each of these bridges
A comprehensive mitigation and conservation strategy program (CMCS) that increases overall efficiency and project delivery
A streamlined, money-saving compliance permitting process

Design Engineering

Idaho 16, US 20/26 to Idaho 44 – Ada and Canyon Counties, ID
With a limited number of Boise River crossings in the area and limited access between Boise and Nampa to I-84 to the north, construction of this new highway segment is vital for providing an essential north-south mobility linkage. Parametrix is providing preliminary design, final design, and PS&E for construction of 2 miles of new highway from US 20/26 to Idaho 44 including two bridges to cross the Boise River and Phyllis Canal. Parametrix is developing transportation solutions and corridor preservation strategies for these two regionally important highways. These projects will determine design features, ROW needs, and local road networks for more than 30 miles of urban and rural highway. In related projects, Parametrix led the corridor preservation study for 15 miles of US 20/26 and was responsible for environmental impact evaluation and access management for the corridor preservation study for a 19-mile corridor of Idaho 44.

SR 522/Fales Road Interchange – Snohomish County, WA
The Fales Road grade separation project, part of the SR 522 corridor widening effort, features a single point urban interchange, which minimizes the footprint, significantly reducing environmental impacts and right-of-way requirements. The new over crossing structure is a single-span 197-foot post-tensioned box-girder that will be built for three lanes of traffic and can be widened to seven lanes in the future. Parametrix provided design services, project management, surveying, and environmental support.

Franklin Road, Linder to Black Cat – Meridian, ID
Parametrix is providing design and environmental clearance services for this urban arterial road widening project. Elements of the project include roadway design, intersection design, right-of-way analysis, storm drain design, water quality design, and irrigation relocations. Parametrix performed a traffic analysis to determine appropriate segment and intersection lane configurations to accommodate future traffic projections. We will also complete design plans, signing and pavement marking plans, construction traffic control plans, and construction cost estimates.

The project included public involvement and extensive coordination with the County and City agencies.

5th/9th Street Connector – Puyallup, WA
The 5th/9th Street Connector project created a more direct north/south route on the west side of the Western Washington Fair and allowed for expansion of the fairgrounds across 5th Street. Parametrix performed planning, permitting, design, and construction administration. The project involves shared stormwater detention/treatment facilities, three new signalized intersections, and approximately 7,000 square feet of retaining walls to minimize wetland impacts. Environmental work included design of a 5-acre mitigation site providing both wetland mitigation and stream restoration for salmon habitat.

Bridges and Structures

US 97 Green Springs Drive Bridge – Klamath Falls, OR
Parametrix prepared the design acceptance package and final contract documents for the Green Springs Drive Bridge for ODOT. The bridge is a Stage 1 project of ODOT’s OTIA Bridge Replacement Program. The project was completed on an accelerated schedule, with final design documents completed in six months and construction completed in 11 months. The bridge spans Green Springs Road, Burlington Northern-Santa Fe railroad tracks, and wetlands on US 97. The environmental permitting effort was streamlined because Parametrix had previously prepared baseline reports for this bridge under the statewide bridge replacement contract. Prestressed bulb tees were selected as the preferred alternative. Bridge design was complicated by super elevation in a horizontal curve and by its location on a sag vertical curve.

I-5/116th Street NE Interchange – Snohomish County, WA
Parametrix is designing the complete reconstruction of the existing 116th Street NE interchange north of Marysville. The new single-point interchange will provide additional capacity for planned growth in the north Snohomish County area, including the Quil Ceda Village Business Park. Major elements of the project include a NEPA EA, traffic analysis, an access point decision report, design for a 150-foot-long bridge and wall, realignment of a major county arterial, stormwater treatment and infiltration design, signal design, and preparation of PS&E to WSDOT standards.

SR 520 Bridge Replacement – King County, WA
The SR 520 corridor is approximately 15 miles long and connects Seattle (at I-5) to Bellevue, Kirkland and Redmond (east of I-405). Within this corridor is the Evergreen Point Bridge crossing Lake Washington. Parametrix is evaluating opportunities to improve mobility for people and goods across Lake Washington and is preparing a project-level NEPA/SEPA EIS. Four, six, and eight lane alternatives are under consideration. Over 50 different interchange configurations have been considered at over 15 locations throughout the corridor.

Columbia County Bridges – Columbia County, OR
Parametrix is working with Columbia County to design seven replacement bridge structures. Construction will take place in two phases. Phase one involves four structures, including the two highest ADT volume bridges, and phase two contains three structures. The existing structures range in length from 20 to 80 feet and were constructed of either concrete or timber. The replacement structures vary in length from 40 to 110 feet and are designed utilizing prestressed concrete elements (six are prestressed voided slabs). Construction scenarios for the replacement bridges were designed to accommodate a restrictive in-stream work window because the structures cross tributaries that drain into the Columbia River. As part of our scope of services, we are providing environmental permitting, wetland delineation, roadway realignment and right-of-way, traffic control, surveying, geotechnical investigations, and hydraulic analysis.

Park Meadows Pedestrian Bridge at County Line LRT Station – Lone Tree, CO
Parametrix is designing a new pedestrian bridge with vertical circulation structure from the RTD County Line Station platform to the Park Meadows Mall property. The bridge consists of enclosed steel through truss with a total bridge length of just less than 100 feet. The vertical circulation is provided by a pair of elevator towers and a separate stair tower. Parametrix provided overall project management along with all structural engineering requirements for the project.

Transit and Light Rail

West Valley City Light Rail Project – UT
Parametrix was the lead environmental consultant for the Utah Transit Authority’s (UTA) proposed West Valley Light Rail Transit project, a new 5.2 mile line from the North-South TRAX line in Salt Lake City to West Valley City, the second largest city in Utah. The project includes elevated, at-grade, and in-street running segments; crossed a river, a major rail yard, and an interstate; and connects to a major new intermodal hub with bus, BRT, and light rail service. Key issues include arterial traffic operations, historic resources, neighborhood effects, floodplain and nature area impacts, and noise and vibration. The project was UTA’s first-ever non-federal environmental review for a light rail project. Parametrix assisted UTA in refining the environmental approach and documentation requirements for the project. Other project partners included UTA, the Wasatch Front Regional Council, the Utah Department of Transportation, West Valley City, and the City of South Salt Lake.

Milwaukie LRT SDEIS – Portland, OR
For Portland’s Metro and TriMet, Parametrix is managing a fast-track NEPA SDEIS for this 5-plus mile extension of Portland’s MAX system from downtown Portland to the South Waterfront District, across the Willamette River to Southeast Portland and on to Milwaukie. A new bridge across the Willamette River is a major element, as the river is critical habitat to several endangered salmon species. The corridor crosses near Superfund site areas that are being redeveloped as urban centers. The new bridge is proposed as transit-only, potentially carrying streetcar and buses, but would also include a bicycle and pedestrian trail. The remainder of the light rail alignment is mostly at-grade, with some sections involving in-street running, and other sections that share or expand existing rail, street, or highway rights-of-way.

Link Light Rail Transit Environmental Services – WA
Sound Transit’s Link light rail system includes Tacoma Link (now built and operating), and Central Link, a $3 to $4 billion LRT line extending from north Seattle, through the University District, Capitol Hill, downtown Seattle, south Seattle, and Tukwila to Sea-Tac International Airport. Parametrix led the environmental documentation including alternatives analysis for light rail route, station, and maintenance base alternatives. Parametrix developed the Central Link and Tacoma Link Final EIS documents in 1999, and has since developed the NEPA/SEPA environmental documents for several refined operating segments of Central Link, including the Tukwila Freeway Route, the Initial Segment, Airport Link, and the North Link/University Link SEIS.

River Rail Trolley – Little Rock, AR
Parametrix provided design and construction services for a streetcar system including track, stations, overhead contact system, and a trolley maintenance facility. The first phase of this system will connect the Alltel Arena, historic downtown Little Rock, and North Little Rock, running on existing streets and traffic areas. More than two and a half miles of track work have been designed including continuously embedded and direct-fixed track. The project involves significant coordination with various utilities, city, and state agencies. A major milestone is the modification of the Main Street Bridge to allow the trolley alignment to cross the Arkansas River while maintaining four lanes of traffic on an existing bridge. The design employs the latest track construction technology to minimize disruption during construction of downtown businesses and utilities.

South/North Light Rail Corridor EIS – OR and WA
This $2.8 billion, 22-mile, South/North LRT corridor links Clackamas County, Oregon to Vancouver, Washington. The corridor passes through three central business districts (Portland, Milwaukee, and Vancouver) and over two major rivers (Columbia and Willamette). Parametrix led the environmental analysis and completed the draft and final EIS, including special studies for compliance with the ESA, Clean Water Act, Section 106, Section 4(f), land use goals, and other federal and state regulations.

Parametrix is supporting the client in the analysis of the failure that caused the collision of two automated trains during testing on August 4, 2002. Included in the analysis is the explanation of various testing that has been conducted, the adequacy of the fleet, evaluation of the cost to repair the vehicles, and an investigation of the cause of emergency stops.

Roosevelt Island Tramway – New York City, NY
Parametrix is providing operations and maintenance oversight services for the Roosevelt Island Operating Corporation. We have performed various analyses to determine the expected life of certain components and have overseen redesign. The Roosevelt Island Tramway was placed into service in 1975, providing a transit option from Roosevelt Island, in the East River, to Mid Town Manhattan. The tramway is a double reversible system with two 125-passenger cabins.

Roundabouts

Selah Loop & Gore Road Roundabout – Yakima County, WA
Parametrix conducted an intersection alternative analysis for the intersection of Selah Loop and Gore Road to identify future lane configuration requirements to meet 20-year traffic growth projections. The County selected a modern roundabout alternative and Parametrix has completed the preliminary design for the roundabout improvements.

Yelm Highway Corridor – Thurston County, WA
Paramerix is providing final design, right-of-way plans, and PS&E for the widening of Yelm Highway from two to five lanes from Henderson Boulevard to Rich Road, approximately 6,000 feet. The design includes two roundabouts, one replacing an existing signal. Project elements include alignment options, public presentation of options, right-of-way plans, biological and environmental assessment and cost estimates.

45th Avenue Roadway and Roundabout Design – Lacey, WA
45th Avenue, from College Street to Ruddell Road, was a two-lane city neighborhood collector street approximately 3/4-mile in length. This stretch of roadway was improved to include left-turn lanes into existing subdivisions, curb and gutter, sidewalks, bike lanes, street lighting, storm drainage, landscaping and irrigation, and underground of private utilities.

In addition to the roadway improvements, a two-lane modern roundabout was constructed at the intersection of 45th Avenue and College Street. As well as preparing PS&E for the roadway project, we prepared a separate set of plans for the roundabout, including roadway and storm drainage design, street lighting design, and landscape and irrigation design.

Highland/Siskiyou Intersection Improvements – Medford, OR
Parametrix worked with the City to determine the most appropriate intersection control device for this suburban intersection. Both a signalized intersection and a modern roundabout were considered. Several elements, including operations, safety, access, and ROW impacts were considered. A major element of the project is an outreach and education program with the local community. The City selected a roundabout alternative and Parametrix is currently completing the final design.

Littlerock Road Corridor Improvements – Tumwater, WA
In 1997, the City of Tumwater adopted a Supplemental Environmental Impact Statement (SEIS) for the Littlerock Road SubArea Plan. The recommended plan included “substantial intervention” for Littlerock Road, including developing the roadway as a median-divided, tree-lined boulevard. The plan also called for incremental development of a frontage road, which would relieve Littlerock of much of the future development traffic. An internal roadway grid network, streetscape, and pedestrian improvements were also recommended. In 1999, the City received a grant to proceed with design and construction of the improvements to Littlerock Road. Parametrix managed the corridor development process, which included a design fair, focus groups for commercial and residential interests, and a design charrette. Special focus in outreach centered on educating the public and an advisory on the use of roundabouts on an arterial corridor. Recommendations from the public process were summarized in a Corridor Development Plan that includes the opening year and 2020 transportation blueprints, streetscape features, and land use issues.

Bethel Road Corridor Improvements – Port Orchard, WA
Parametrix managed and designed the Bethel Road Corridor project. Bethel Road is a commercially zoned corridor in south Kitsap County. Current land uses along the roadway range from residential to retail. In recent years, commercial development has begun to spring up along the corridor, site by site, with no plan for the corridor as whole. Compounding this is ever-increasing traffic and the acknowledgement that widening or other improvements would be necessary to accommodate future traffic volumes. In order to guide commercial development, rather than allow development to drive roadway improvements, Kitsap County felt a more comprehensive process was needed. The first phase of this process evolved into a Corridor Development Plan, and is the first such plan to be produced for a county roadway. There are four components to the plan: land use, transportation, street, and environmental.

The next major phase of this project was the design of the roadway improvements. The design elements include a four lane roadway with a landscaped median with turning pockets, two new signalized intersections, one signal upgrade, and two modern roundabouts. The completed project will result in a new 1.5 mile improved corridor that will accommodate future motorized and non-motorized traffic for many years. Recipient of the 2000 APA Transportation Planning Award for Outreach.

Evergreen Parkway Improvements – Olympia, WA
Parametrix designed improvements to Evergreen Parkway, including a roundabout at McCann Plaza and Overhulse Drive. The improvements, which include a non-motorized pathway and planter strip, significantly reduced the total impervious area of the parkway, which was converted from two lanes in each direction to a single lane. The conversion meets Evergreen State College’s goal of sustainability and environmental stewardship by eliminating the travel lane and replacing it with facilities for pedestrians and cyclists, as well as creating a new planter strip area. These improvements also serve to slow and calm traffic, since speeding on the parkway is a major safety concern. Parametrix also provided full construction management services. Recipient of the 2005 WSDOT Pedestrian Safety Enhancement Award.
