Introduction The North Fraser Perimeter Route Mitigation Options Analysis is in response to the City’s active work to concentrate a large share of local housing and employment growth in the Downtown in keeping with its role as a Regional Town Center in the Greater Vancouver regional growth strategy. Today, the region’s major goods movement corridor operates on East and West Columbia and Front Streets, creating a barrier between Downtown and new riverfront development. It also limits pedestrian and bicycle access to open space opportunities on the Fraser River waterfront.
New Westminster is at the heart of the greater Vancouver metropolitan area once serving as the capitol of British Columbia. Its early beginnings centered on the Canadian Pacific Railroad and an active working waterfront and harbour on the Fraser River. The remnants of New Westminster’s industrial and shipping past remain today with freight rail and heavy trucking following the traditional routes to and from the Barard Peninsula and west coast ports. North of Front Street is the historic downtown district with an impressive cross section of architecture that represents the heritage and culture of New Westminster since the early beginnings of the province.
Capacity along this corridor is expected to increase as a result of improvements planned under the Provincial Gateway Initiative and the Greater Vancouver Transportation Authority’s Three Year Plan and Long Range Outlook. Competition between the goods movement corridor’s heavy truck and rail traffic and regional and local pressure to accommodate high density, mixed use neighborhood development motivated the City to analyze options for mitigating future increases in traffic while removing noise, poor air quality and neighborhood severance disbenefits.
A major goods movement corridor between the Fraser River waterfront and Downtown on and parallel to Front Street is an essential regional trucking and rail link serving the country’s largest volume import and export trade. New Westminster is also at a regional freight cross roads of the Trans-Canada Highway and the North Fraser Perimeter Route and a major Fraser River freight railroad that provides access for eastbound and westbound rail traffic. Combining truck and rail freight movement, New Westminster and the North Fraser goods movement

corridor has the highest volume of freight to and from ports of the greater Vancouver metropolitan region. Trucks represent 63% of the midday traffic with an estimated total of 5,000 to 7,500 trucks per day on Front Street. Freight rail traffic is equally heavy with up to 60 trains per day. Assuming that no trucking destinations are between Highway 1 and West Columbia at 5th Street, trucks are traveling one-half mile out of direction further than with a more direct route. The one-half mile out of direction travel represents approximately 3,750 miles per day, nearly 950,000 trucking miles per year by 1.9 million trucks annually.

4th Street
In addition to the heavy volume of trucks and trains that rely on this route, there is an at grade crossing of the railroad at Front and 4th streets. This grade crossing appears to contribute to the inefficiencies of this route by causing significant trucking delays which exacerbate poor air quality and the amount of lost trucking time.

At the same time, New Westminster’s responsibility as a Regional Town Center in the Greater Vancouver regional growth strategy is to absorb metropolitan jobs and housing growth. New Westminster is the second largest center for financial services in the region. Downtown has spectacular views overlooking the Fraser River and beyond to Surrey. SkyTrain provides regular downtown service at two stations within two to three blocks of the waterfront. Downtown New Westminster is targeted to absorb 250,000 square feet of office space, 140,000 square feet of retail and service and 4,800 residential housing units between 2003 and 2021. The waterfront between 2nd and 8th Streets represents approximately 8 acres of underdeveloped property and is one of the largest and most attractive development sites in the City. This area represents the potential to absorb nearly all of the Downtown sector growth. Over one third of the targeted residential units and office space as well as approximately 125% of the targeted retail/service space are currently being reviewed by the City.
Recently, two major projects that propose to add approximately 1,700 residential units, 86,000 square feet of commercial and 174,000 square feet of retail uses will straddle Front Street and the rail line. Significant open space and esplanade improvements are proposed with these two projects which will likely increase the pedestrian, bicycle and vehicle demand to cross Front Street and the railroad at 8th and 6th Streets. In view of these proposed developments and a significant amount of underdeveloped riverfront property between 6th and 4th Streets (8 acres +/-), access for cars, pedestrians and bicycles and mitigation of air quality and noise from the Front Street corridor is essential to achieving the New Westminster vision for livability and an active, vital and connected waterfront. Following is a brief contextual analysis and an urban design diagram that provides the framework for 5 mitigation options for Downtown between McBride and 10th Street along Front Street. The mitigations options consider development opportunities presented by implementing mitigation measures and strengthening connections to the Waterfront.

Case Studies Competing interests between transportation and livability are common tensions found in most cities. Some cities have balanced these competing interests by encapsulating existing highways and railroads while others have relocated transportation system elements into underground tunnels. Oslo, Norway and Boston held many of the same urban values as New Westminster and invested in encapsulation and tunneling projects that balanced the critical need for mobility while enhancing and preserving livability, cultural heritage and their historic architectural treasures.
Portland, Oregon explored encapsulating the Interstate-405 (I-405) corridor in downtown. The vision was to cap the existing depressed freeway and reconnect 2 historic Central City Districts - the Downtown and Goose Hollow Neighborhood districts. Potential new development area and much needed open space to serve businesses, the neighborhood and Portland State University which is Portland’s largest urban university.
A tunnel ring road system was developed to preserve the historic architecture from 1100 urban scale and form of Oslo.
Tunnel alignment
A surface highway separated the State House and Downtown Oslo from its waterfront. The Tunnel alignment shown above illustrates the route that reaches under some of the City’s oldest and most culturally and historically significant areas. March 13, 2006
The “Big Dig” underground highway and railroad system was essential to preserving the heritage of Boston and the country.

Strengthens commercial, retail and restaurant uses on 8th, 6th, and 4th Streets
•
Provides the most cost efficient and affective options that balance transportation and land use
Evaluation Criteria
•
The following eight evaluation criteria are based on the project objectives and are used to evaluate each option.
Maximizes development potential by creating new developable lands
•
Provide access to existing buildings that face Front St.
•
Balances physical improvements with costs and City objectives
•
Eliminates truck and train grade crossing at Front and 4th Streets
•
Optimizes project phasing to minimize construction impacts
An initial site visit included an overview of the issues and challenges and provided a forum for City staff to describe the scope of the project from various points of view. The process was inclusive of City departments through conducting two full day workshops with staff and management. During the initial workshop, staff reviewed case studies (Oslo, Norway; Portland, Oregon; Boston, Massachusetts; and Atlanta, Georgia), the project context and five conceptual options of different mitigation techniques. The second workshop was structured for review and comment on the draft report including refined options, costs and feasibility of the various mitigation options. It also included review and comment on recommendations and project phasing.
Policy Objectives A compilation or relevant goals, objectives and initiatives from the Livable Region Strategic Plan, the 2005-2007 Three-Year Plan & TenYear Outlook and the Downtown New Westminster Action Plan provided the basis for creating project specific objectives and evaluation criteria for analyzing options. The North Fraser Perimeter Route Mitigation Options Analysis considers the following objectives: •
Preserve and enhance the functions of the North Fraser Perimeter Route for regional and national goods movement.
•
Improve air quality to meet or exceed standards for sustainable livability.
•
Mitigate truck and railroad noise in the Front Street corridor.
•
Reduce freight, rail and truck conflicts.
•
Preserve and enhance views and view corridors from downtown to the river.
•
Reconnect the downtown to the river’s edge by creating people friendly links across Front Street and the railroad and creating places that reflect New Westminster’s cultural and historic identity.
•
Identify costs for multiple phases of mitigations and improvements.
•
Determine construction feasibility and construction impacts. The underdeveloped waterfront wharf presents an opportunity to strengthen the commercial and retail viability of New Westminster while achieving regional growth and livability objectives. 5

Context Brief History New Westminster is a long established city with a deep historic and cultural heritage dating to the founding of British Columbia’s economic base and provincial government. Over the past 146 years, it has been at the transportation crossroads of the province and the metropolitan region. The traditional transportation patterns established during New Westminster’s early years exist today and influence the City’s future development as it strives to meet the expectations of a Regional Town Center. While the historic transportation patterns remain, the remnants of a heavy industrial working waterfront provide challenges and opportunities fro reactivating the abandoned wharves.
Land Use, Parks and Open Space Recent planning efforts have placed the focus of New Westminster’s vision on the waterfront. Land use designations have evolved to address regional and local growth goals. Parks and open space concepts reinforce connections to the shoreline while historic preservation and smart growth strategies emphasize the importance of the river to the City’s livability, cultural enhancement and strength of its business core.

Transportation and Parking Central to the City’s goals and objectives of promoting Downtown’s economy is the transportation and parking network. And central to Downtown is the Front Street Corridor which is also part of the provincial and metropolitan highway system. Front and Columbia East and West are designated Major Regional Arterials and Truck Routes that link Highway 1 and Marine Way through New Westminster. McBride is an intersecting Regional Arterial and Truck Route that links Front and Columbia Street East with 10th Street and Burnaby to the north and Surrey to the south via the Patullo Bridge. Queensborough Bridge routes truck traffic from the Front Street Corridor south to Delta via the Annacis Connector. Approximately 7,500 trucks per day use Front Street to access distribution points.
Historic Resources Area
SkyTrain travels east and west through Downtown serving 8th and 4th Streets between Columbia and Carnarvon. Both stations are approximately two blocks north of the waterfront. A complete bicycle and pedestrian network links civic destinations, parks and the waterfront. The Front Street railroad lines were originally established in 1887 and serve local terminals, yards, western ports and greater Canada. Two rail lines provide regular daily service through Downtown with 30 to 60 east/west trains per day with 80% in the eastbound direction. There is an existing grade crossing conflict near 4th and Front Streets where trucks experience significant delays. Downtown is served by on-street parking in all areas. According to the 2004 Retail Impact Assessment for Columbia Street, on average, onstreet parking on Columbia and associated side streets is at capacity. To supplement Downtown on-street parking in the mid-1960’s, the City built a 3-storey parkade which today holds approximately 769 parking spaces. The parkade is essential to the vitality of Downtown businesses. A 1999 Downtown Parkade Study by IBI GROUP recommended the existing structure had reached the end of its life cycle and should be rehabilitated and maintained until a new replacement becomes financially feasible. The report further recommends a minimum of 600 parking spaces with possibly up to 925 parking spaces are needed on Front Street. The report suggests a phased project that would cover Front Street and the railroad and would provide noise and air quality features to mitigate transportations impacts of the truck and rail corridor. The concept also would provide vehicle pedestrian and bike connections to the river with a variety of 6

urban spaces.
Urban Design The urban design framework diagram builds upon significant previous work. Envisioning a tunnel system that enables complete connectivity between Downtown and the waterfront helps expand urban development possibilities. Green streets, a continuous riverfront esplanade, SkyTrain and Columbia Street create layers of infrastructure that direct urban growth toward the river. A major downtown gateway between 8th and 10th at Columbia and Front reinforces the identity of downtown. The elimination of the Front Street and railroad barrier and an opportunity for three major attractors on the water would help activate the waterfront as well as Columbia Street, SkyTrain station areas, 6th Street and Downtown in general. The concept reinforces the Market and Discovery Center by adding significant active uses on the river at the end of 6th and 4th Streets. Uses might include a Lacrosse facility, entertainment or destination meeting and conference center. In any event, right-of-way should be preserved for future commuter rail or streetcar transit. The concept also envisions extending the commercial and retail uses from Columbia to the river on 8th, 6th and 4th Streets creating a series of pedestrian loops between destinations. Front Street would become a viable green street with active uses and access to waterfront properties. With the long tunnel option, nearly all of inner New Westminster from Highway 1 to Columbia Street West would enjoy convenient and comfortable access to and along the Fraser River.

Challenges Following is an outline of existing challenges where there are conflicts between City goals and objectives, transportation modes and residential commercial and development proposals. •
The “no growth” transportation policy provides a natural cap on traffic increases through Downtown. However, stop and go traffic at the grade crossing between Front Street and the railroad as well as stop control and traffic signals affect travel time and increase noise and air pollution.
•
The significance of the North Fraser Perimeter Route to the region and the province is such that it must remain in New Westminster in some form in the future.
•
Current volumes of truck and rail traffic produce significant air quality concerns as residential riverfront and upland development encloses the Front Street corridor and more people begin living in the area.
•
The grade crossing at about 4th and Front streets creates a conflict between trucks and trains and adds a significant delay to freight truck movement.
•
The continuous volume of trucks and trains and the gap between Columbia Street and the blank walls of new parking structures increases the psychological barrier between Downtown and the Waterfront and exacerbates noise impacts.
•
Spectacular local views of the river are interrupted by the parkade and the high volume of truck and rail traffic on Front Street.
•
Because of few connection points over or across the existing Front Street corridor there are limited opportunities to create a strong connection between Downtown and the riverfront.
March 13, 2006
•
New Westminster is designated a Regional Town Center which is a regional growth strategy to concentrate high density commercial and residential growth within available urban areas near high level transit access while protecting the Green Zone. The New Westminster waterfront contains significant underdeveloped area for residential and Green Zone development that is within convenient walking distance of two SkyTrain stations and regular bus service. SkyTrain and much of the underdeveloped waterfront property are separated by the Front Street corridor.
•
New residential development is pending and likely to occur within the next 5 years. Interim connections and mitigation measures are being considered to enable development while increasing the inhospitable quality of Front Street and the historic building resources that line the street’s frontage. The net result of these actions would create a trench between the proposed LARCO parking structure podium and the under utilized lower level of historic buildings on the north side of Front street. The trench would trap noise and pollutants from trucks and trains reinforcing the perceived barrier of Front Street and potentially degrading the viability of the historic properties.
•
Any encapsulation solution that reconnects Downtown to the Waterfront will have significant cost and will likely prevent future expansion of roadway or rail facilities. Over time, as development proceeds, this would likely force future administrations to revisit this same issue for east and west stretches of the Fraser River and alternative routes for freight movement.
•
Because of limited work area and the need to keep truck and rail traffic moving, significant improvements to encapsulate or make surface enhancements and mitigations will have construction impacts on new development, historic building protection, Downtown businesses, freight

OPTION III RELOCATE ROADWAY AND RAILROAD TO A TUNNEL Tunnels The North Fraser Perimeter Route Mitigation Options Analysis includes long and short tunnel alignments for Options 3 and 4. Tunnels provide an opportunity to route heavy truck and rail traffic outside of the New Westminster downtown waterfront area while avoiding other surface streets. These options also route goods movement traffic on a more direct route reducing travel by as much a one half mile or more. While this travel reduction seems modest it translates into approximately 950,000 fewer annual trucking miles or approximately 3,750 miles per day. Another benefit of the highway tunnel alignment option is the routing of commuter traffic to a more direct route without impacting neighborhoods or corridors.
Three Lane Highway Tunnel
Routing the railway into a tunnel benefits the City by eliminating the current barrier and reduces grade crossing conflicts for the railroad. Railway travel savings are less than those of the trucking alignment because of required access to the Fraser River crossing and rail yard locations.
Typical rail portal: West Portal, Westside Corridor LRT, Portland Oregon.
Both alignments could be expanded to accommodate more travel lanes or tracks. Intersections and switching locations would require geometric design to understand the extent and feasibility of making connections to alternative portals, alignments or other facilities. Distance savings and elimination of rail and truck delays would make the highway tunnel alignment an attractive route for carpool, bus and automobile commuters.
Emergency smoke evacuation fans
Typical fan component
Vent shafts would require land above the tunnel alignments for equipment and access. These facilities can be relatively inconspicuous but will consist of a modest headhouse with short vent stacks or louvered exhaust ports for supply and return air. These facilities will likely contain emergency access, smoke evacuation fans and equipment as well as safety and security monitoring.

Preliminary Recommendations The City of New Westminster should proceed with a phased approach to reconnecting the Fraser River waterfront to Downtown Westminster. Phasing would occur over the next decade and would address immediate needs for development and transportation while proceeding with a major regional realignment of the freight truck and rail routes through a tunnel. Since many of the immediate improvements that are identified in the current capital improvements plan will benefit Downtown regardless of rerouting truck and rail freight traffic, the phasing would build upon current and planned expenditures. Moratorium or not, traffic capacity and moving more cars and trucks through, to and from the city will eventually become necessary to maintain balance between livability and Downtown viability. Following are two potential phasing approach.

2005-2007 THREE-YEAR PLAN & TEN-YEAR OUTLOOK Regional Roads-Greater Vancouver Transportation Authority (GVTA) Major Projects With the continuation of the $35 million Major Road Capital annual allocation in the 2005-2007 Financial Plan, a total of $230 million in accumulated capital will be available for Major Road investment in the period to 2007. The following table shows the recommended projects: x x
The GVTA Board has approved, in-principle, the Fraser River Crossing (FRC) and project development is well underway. The new crossing will be predominately self-financed through tolls and therefore will not require significant additional capital from Major Road Capital funds. The Dollarton Bridge twinning, Fraser Highway widening and the North Fraser Perimeter Road are identified in the GVTA’s current Strategic Transportation Plan that was approved by the GVTA and GVRD Boards in 2000.
The Three Year Outlook includes $60 million to fund infrastructure improvements to the North Fraser Perimeter Route through New Westminster. The money is currently intended for an above-grade crossing at Braid Street and Brunette Avenue; intersection improvements at McBride Boulevard-Columbia Street East; signalization at the Sixth Street-Front Street intersection; and, reconfiguration of the Royal Avenue-Stewardson Way intersection.

GOAL: The Downtown has spectacular views of the Fraser River. Residential and commercial developments should take advantage of these views, as well as their proximity to the Fraser River.
x
Several of the buildings on Columbia Street are excellent examples of Victorian and Edwardian architecture. Other buildings on Columbia Street look “tired”. Many of these buildings need facade restorations and several of these buildings need uses’ for their vacant upper storeys. One concept to help address the physical barrier between the Waterfront and Columbia Street is a land bridge over the railway tracks. This land bridge could be connected between the Eighth Street SkyTrain Station and the Waterfront. This land bridge could also connect public transit users from the SkyTrain Station to Downtown’s destinations - the Westminster Quay Public Market and the soon to be built, Fraser River Discovery Centre. To support retailers in the Downtown neighbourhood, an increase in the residential base is needed. There is an opportunity to build residential conversions in the upper storeys of historic buildings along Columbia Street and throughout the Downtown. Loft housing, artist work/live studios and single room occupants could all be viable residential uses for the adaptive reuse of historic buildings. It is envisioned that the esplanade will be extended from the Westminster Quay Public Market all along the Fraser River providing public amenity space and public access. Also, public transit could be extended in the Downtown with a transit turnabout at the foot of 6th Street next to the Waterfront. The foot of 4th Street along the Waterfront could be an ideal location for a waterfront marina development providing public moorage facilities.

city are seamlessly connected, forming a vibrant civic and mixed use neighbourhood and destination. The tunnel is under Akershus Castle, the town hall plaza and much of the waterfront. The total length is approximately 3,000 M, with 1,520 M tunnelled through hard rock and 270 M in cut-andcover tunnels. “The cost for the Oslo Tunnel segment was USD 81 million or approximately USD 53,000 per meter, ventilation, lighting, traffic control and emergency equipment not included.”
Oslo, like many cities, made extensive highway plans during the 1960’s. At the same time, Oslo developed an extensive mass transportation system including a subway to serve its central city. Approximately 30% of trips across the outer tollring use mass transit while approximately 80% of trips within the inner ring use transit. At the time of mass transit development, Oslo was the only city to have a subway with a city population under one million. Over the past decades, growth in traffic volumes has overwhelmed the capacity of the surface road and highway system. By 1986, highway capacity was exceeded all day long. What road network that had been constructed was environmentally unacceptable. Planning for new roads assumed relocation of trips on the over crowded street system. Collectively, the city desired to preserve the medieval dense city structure and street network. As much as 70% of the new road network in Oslo is planned to be in tunnels.
Allowed capacity expansion to 100,000 average daily trips without the destructive impact of heavy through traffic. The rock tunnel reduced costs, minimized “serious settlements” and avoided conflicts with building entrances.
The Oslo Tunnel is a six-lane, twin tunnel highway that travels under the waterfront of the central city and can accommodate average daily trips of 100,000. This tunnel replaces eight lanes of surface traffic carrying 80,000 vehicles per day that originally used roads that separated the town hall from the waterfront. Much of the waterfront was used for shipping and industrial uses. Today, central Oslo’s waterfront and central

Case Study 2: Bridge the Divide and Cap I-405 Vision Study The results of the vision process added up to recapturing 26 of the original 30 blocks lost to the freeway and:
Portland, Oregon USA Description
x x x x x x x
Between 1964 and 1966, the I-405 was constructed through southwest and northwest neighbourhoods in Portland. The road is designed to carry over 100,000 daily vehicle trips. The depressed freeway linked the I-5 and Highway 26 regional corridors which serve the central city, the metropolitan region and interstate transportation. While I-405 has provided regional and through access in the central city it also removed heavy traffic from downtown surface streets avoiding detrimental impacts on Portland’s liveability. However, while the project enhanced downtown liveability it severed neighbourhoods to the west from seamless access to central city shopping, jobs, entertainment and Portland State University. It also interrupted neighbourhood paths to the Willamette River. Ultimately I-405 physically divided the central city community and retarded development along its edges.
1,000 housing units 650,000 square feet of commercial space 1,800 permanent jobs 2,200 parking spaces 6 acres of parks 2 acres of indoor recreation uses 50,000 square feet of civic and recreation uses
A technical assessment of a 21/2 block area at a MAX Light Rail Station was used to determine feasibility. A pre-cast concrete deck system was modeled for constructing a buildable platform for development. The bridging system concept would act as a foundation for future development with a superimposed design load of 1,000-psf. This loading capacity would typically support a 7-story, steel-frame building with parking on the deck level. The estimated cost of pre-cast concrete deck construction for 21/2 blocks was USD 16 million or USD 160 per square foot based on 2000 costs. These cost estimates did not include acquisition of air rights, design and permitting costs and local public infrastructure improvements.
Capping the freeway was first identified in the 1970’s by the Goose Hollow Neighborhood which shares its easterly border with I-405. Later, during the Central City planning process, City planners identified capping the freeway as a vision for Portland and included the idea in the 1988 Central City Plan. In 1998, Mayor Vera Katz initiated a 6 month design process with the American Society of Landscape Architects to involve the community in exploring capping options to reclaim 26 of the original 38 blocks that were lost to the freeway project.

Much of the landward segments of the project were encapsulated using a slurry wall system which is a form of cut-and-cover construction. The slurry wall system begins with thin trenches that are filled with liquid clay (slurry) to help retain the trench profile. Reinforcing, up to 100 feet in depth, is craned into trench segments and followed with pumped concrete. The heavier concrete displaces the slurry as the trench is filled. This system reduces the width of excavation and enables the final walls of the cut-andcover facility to be in place prior to excavation.

Reconnected downtown Boston neighbourhoods and districts. Created 260 acres of open space, parks and plazas
Reclaim damaged neighbourhoods, businesses and the Boston “way of life.” Add open space to the North End which is underserved for outdoor recreation. Minimize impacts of freeway noise and air quality.
Building underwater, and underground in a dense urban environment.
Reclaimed downtown city streets from elevated roadway and grid lock.
The project has spanned 30-years with construction budgets beginning at USD 2.6 billion in 1983 and escalating to USD 15 billion in 2005. The Big Dig is eight linear miles of 4 to 12 lane subterranean highway constructed underground or underwater in combination with surface, bridge and viaduct segments. The project enables the reclamation of a 100-acre city dump, 44 acres of and industrial corridor and 27 acres of downtown land made available by the removal of the elevated highway. These lands are being converted into public open space and parks in the heart of downtown Boston. Another added benefit of The Big Dig was that the project necessitated rebuilding outdated utilities some as old as 150 years.
