earth hour 2014 – celebrating our commitment to the planet

Nelson Mandela – “Let us stand together to make of our world a sustainable source for our future as humanity on this planet”

Earth Hour is an annual global event that is held on the last Saturday of each March to raise awareness of climate change, and to encourage each of us to make choices that will lessen our impact on the environment. This remarkable initiative first began in Sydney, Australia in 2007 with 2.2 million Sydneysiders [A native or inhabitant of Sydney, Australia] and 2,100 businesses taking part. To date it has grown to over 6950 cities and 152 countries worldwide.  In 2012 Vancouver was recognized as the first Global Earth Hour Capital. The City of Vancouver has set green targets of being a global leader on climate-smart urban development. Vancouver aims to have all newly constructed buildings be carbon neutral in their operations by 2020.

In reflecting on the true meaning of Earth Hour it raises the question – why wait until March 29 at 8:30pm to make a difference in saving energy or working to reduce climate change? Why not make small changes throughout the year? Small changes like carpooling or taking public transit will help reduce vehicle emissions and pollution. We are seeing these everyday changes right here in York Region with a 38% increase in ridership and over 22.7 million riders on YRT\Viva since 2005.  With the section of the rapidway that is open on Highway 7, you can hop aboard a Viva bus and cut your commute time by up to 40% during the rush hour commute.

Once vivaNext rapidway construction is completed, the sustainable transformation of this urban corridor will support growth, and reduce congestion to help make York Region an even more inviting place to live, work, shop and play. These benefits extend well beyond York Region. For example, the rapidways will also play an important role in a seamless transit system across the GTHA, helping to reduce traffic congestion, increase productivity and provide sustainable alternatives to car use, which help reduce our environmental impacts.

If we all tried, even for one day, to reduce our environmental footprint it would be a symbolic demonstration of our commitment to reducing climate change.  Don’t forget to power down this Earth Hour, our planet will thank you.

taking care near our urban watercourses

If you’ve been at the corner of Jane Street and Highway 7 in Vaughan recently, you’ll have seen the work underway to build a 10 metre long retaining wall near where the Black Creek flows through a large culvert under the roadway.

We’re building the retaining wall to support the newly widened roadway. Ensuring that our project does not negatively affect any of the watercourses adjacent to or crossing our rapidway segments is a top priority for vivaNext, and we have made commitments through the Environmental Assessment phase of the project for how we will carry out that work to ensure there are no harmful effects.  In keeping with this commitment, we need to have the major work on the retaining wall finished this spring before April 1, completing the in-water work before the closing of the pre-established work window.

This “work window” is set by the provincial Ministry of Natural Resources, and is set out in timing guidelines that are applied to construction projects near or in watercourses that are home to any species of fish.  These timing guidelines are intended to protect fish from any impact from construction work being done in or around water, during the critical life stages for fish including spawning migrations, egg incubation and fry emergence.

Provincial guidelines are organized by region as well as by fish species within those regions.  Fish can be divided into those that spawn in cold water (i.e. in the spring) and those that spawn in warm water (i.e. in the fall), with the species in the Black Creek being in the cold-water group.  For that reason, the construction permits require that any work we do in or near the Black Creek be done outside of the period from April 1 to June 30, to ensure that the project doesn’t interfere with their spawning.

Once the work window closes April 1, we will not do any work in or around the water until the beginning of July.  So we go to great lengths to ensure the work on the Black Creek retaining wall is finished by the end of March, and that we won’t need to do any other activities involving in-water work until the summer.

Our commitment to ensuring our work has no adverse effects on the environment goes well beyond avoiding any in-water work at sensitive times.  On all our segments, we work closely with the local conservation authorities, who approve the final designs before we get their permission to work.  Our mutual goal is to ensure the project, at a minimum, avoids any harmful impacts, and in many cases actively enhances the natural environment. We also use various construction strategies to mitigate any potential impacts while we’re working, such as installing cofferdams from sheet piles or sand bags around our work zones within watercourses.   By using these methods, we’re able to work “in-the-dry”, thereby avoiding any risks to the watercourse and its fish, even if the in-water work window has closed.

We’re happy to know that the vivaNext project is going to ultimately enhance our shared environment for people and the other creatures that live in York.  So taking great care as we work near our creeks and rivers is just one example of how we’re committed to protecting and enhancing our natural surroundings, even in a fully-urbanized area like Highway 7 and Jane Street.

Please remember as the temperature heats up during spring thaw, water ways and creeks can been extremely dangerous, remember to keep a safe distance.

what is a culvert anyway?

 

I’m guessing that you probably weren’t thinking about culverts as you sipped your coffee on your commute through the construction this morning — probably not even if you passed right by one. But let me just take a moment to tell you why culverts are important – besides the obvious.

First of all, what is a culvert anyway? Well, I’m sure you’ve seen one by the side of the road, underneath a driveway, around creeks and rivers. A culvert is a tunnel or pipe of varying size, shape and material used to allow water  to move easily from one side of an obstruction (like a road or railway) to the other side.

A culvert has three main functions: to allow for stream crossing; to manage and direct water runoff; and to allow natural wildlife crossing. The first two are pretty self-explanatory, but where it gets interesting is the wildlife crossing.

Since culverts affect both animals and the environment, the Ministries of the Environment, Natural Resources and Transportation have set out specific standards for culverts. Those standards note that they must be constructed in such a way to allow any wildlife travelling through them to see light at the other side. And culverts must include material that mimic the natural landscape of the wildlife passing through it to encourage them to use the culvert for migration.

The typical lifespan of a culvert is somewhere between 10-20 years, depending on a number of factors. When water flows through a culvert frequently, as it does at eastern and western creeks in Newmarket, the culvert will naturally succumb to some erosion. With our plans to widen Davis Drive for the rapidway, we are extending the western creek culvert and removing and replacing the eastern creek culvert that was well beyond its lifespan.

It’s just one more component of an overall transformation towards vibrant urban centres, connected by a rapid transit network to help people get around.

welcoming all cyclists

We’ve been focusing recently on all the features of the new rapidways, which together are going to make transit truly rapid along Highway 7.   But it’s important to remember that many of the design features were developed to ensure that all users of the Highway 7 corridor feel welcome and secure.  This includes transit users, pedestrians, cyclists and drivers – the “complete street” design concept which you can read more about here.  One of the features that have been installed on the rapidways are new dedicated bike lanes and bike boxes, which are painted green.

To provide safety and convenience the new bike lanes will extend 5 kilometres, from Chalmers to South Town Centre Boulevard with lanes on both the north and south sides of Highway 7.  Unlike in many urban settings, York Region cyclists will have these lanes to themselves –our new bike lanes are dedicated, meaning they’re not shared at any point with vehicles.

We’re following the established safety standards, making the lanes 1.4 metres wide, with an additional half metre for a buffer zone between the bike and traffic lanes. Also to give maximum visibility for the bike lanes, they’ll be painted a high-contrast green in the areas around intersections, with special bike-lane markings to clearly identify them in the mid-block.

With the high volume of traffic, the bike lanes will provide a much more comfortable and secure environment for cyclists riding along Highway 7.  But eventually most cyclists will want to turn off of Highway 7, with some needing to make left turns.  Waiting in the left turn lane with vehicles to cross multiple lanes of traffic and the rapidways wouldn’t be safe on a bike, so we’re adding another feature to make the experience better for cyclists.  They’re called bike boxes, and they will make the corridor more welcoming to cyclists.

Here’s how they work.  Cyclists wanting to turn left off Highway 7 will proceed through the signalized east/west intersection in the bike lane into the far side  then stop in a protected area, reserved for cyclists, tucked into the boulevard on the far side of the intersection.  This area, known as a bike box, will offer cyclists a waiting zone while they wait for the light to change.  Once the light changes, they will then cross Highway 7 along with other north/south traffic.

The bike boxes will be clearly marked with green paint like the bike lanes and other markings, so drivers and pedestrians will know they are for cyclists only.  Permanent bike boxes will be put in place this fall and replace the painted ones on the street, so by next spring cyclist will have a great new pathway to follow, with the latest of features.

We’re excited to be providing these new features for York Region cyclists, and know that they’re going to help make this corridor much more welcoming to all travellers, no matter how they choose to get around.

using colour and shape to create welcoming pedestrian spaces

If you’ve walked along the new rapidway on Highway 7, you’ll have seen the vivaNext pavers we’ve installed on the boulevards.  We know from the feedback we’ve gotten that people love the new look.

Most sidewalks in York Region, like pretty much everywhere else, are made of concrete, and the most important consideration is functionality: they need to be safe, accessible, durable and easy to maintain.  But beyond those goals, we also want our new boulevards – which are wider than the Region’s regular sidewalks – to reinforce the complete street concept, the guiding philosophy for our vivaNext streetscape design.  With all the development coming to the Region’s centres and corridors, in the future there will be more pedestrians, whether they live, work, or commute along our rapidway routes.  So we’ve made sure that our boulevard design is going to be visually appealing as well as functional.

The boulevard is made up of the pedestrian zone and the furnishing zone. The pedestrian zone is typically a 2.0m wide sidewalk which is fully paved with light-toned coloured pavers near intersections, and paved with concrete in the mid-block areas. The sidewalk is a continuous system even across driveways to alert motorists that pedestrians have priority.

The furnishing zone is located next to the pedestrian zone. The furnishing zone is an area where pedestrian amenities, furniture and planters are located. It is paved in light coloured unit pavers which reinforce the identity of the vivaNext system.

We’re using a combination of coloured pavers which not only look great but also add to wayfinding for pedestrians.  The main field pavers are light-coloured cool gray with contrasting coloured accent bands which will increase in frequency as pedestrians approach the main intersections. The east-west accent bands are a red; the north-south accent bands are a dark charcoal gray.

Immediately adjacent to the roadway and running along beside the pedestrian zone is a 610mm wide “transition zone”, which will provide an important comfort buffer against bicycle and vehicular traffic. In the winter months, it also provides an area for snow storage and protects the adjacent plantings from salt spray. This zone will be paved in special “eco-pavers”, which allow water to seep through to the storm sewer system.

A charcoal gray coloured textured warning strip will alert visually impaired pedestrians that they are approaching an intersection or driveway. At midblock where the pedestrian zone in paved in concrete, the warning strip will be grooved concrete. Both approaches will provide a tactile clue for visually impaired pedestrians of potential conflicts.

We’ve given special attention to the boulevards near intersections to ensure they reinforce pedestrian priority and add to placemaking. These areas have been designed to function as urban plazas with unit paving and accent pavers. Soft landscaping will define the corners of the intersections and function as gateways to the adjacent areas.

By making the boulevards along the rapidways welcoming and attractive, we’re contributing to the development of York Region’s new urban centres, and adding more walkable places for us all to use.

Rapidways Stations

take a tour of the new station – NOW OPEN ON HIGHWAY 7

We’re really proud of the new vivastations in the median of the Highway 7 rapidway now open; they’re beautiful, they’re functional, and they’re going to make a huge contribution to the transformation of Highway 7 into a more urban corridor.  Anyone travelling along Highway 7 in Richmond Hill or Markham has seen them from the outside, but here’s a peek of what they’re like on the inside.

The first thing you’ll notice as you cross the crosswalk to a station, is how big and airy the canopy is.  At 28m (92’) long and 5m (16’) high, the curved glass soars above the platform, providing both protection and a sense of space at the same time. The platform is approached by a gently sloped ramp with handrails on both sides, making it fully accessible to all, whether they’re walking, pushing a stroller, or in a wheelchair or scooter.  Passing by the familiar viva fin and planted planter boxes, you’ll next come to an illuminated wall map of the YRT\Viva system.

Next on the tour is a bank of fare equipment, including a Ticket Vending Machine (TVM), a Ticket Validator (TV), and two Presto machines. Once you’ve paid your fare, you’ll move to the Fare Paid Zone (FPZ), which is clearly shown by being paved with a different coloured tile on the ground, as well as by a curved sign above.   We need to show this area as distinct, as YRT fare rules require passengers to have paid their fare before moving into the FPZ.

Once you’ve paid your fare, you’re free to make yourself comfortable on the platform until the next bus arrives.  We’re making it easy for you to know how long you’ve got to wait, with a large VMS (Variable Message Sign) projected from the canopy.  The VMS scrolls through all the upcoming arrivals, telling you exactly when the next bus will arrive.  Because the VMS system is connected to the GPS in our actual vehicles as well as the central transit scheduling software, it can be constantly updated to provide accurate and real-time information.

But if you decide you want to sit down on a bench, or get comfy out of the elements, we’ve made that easy too.  The fully heated glass enclosure is well lit, and accessed by two push-button automatic doors.  The heaters – which won’t be needed anytime soon, but you’ll like them come later this year, they’re like the infrared heaters in a hockey arena – will automatically turn on if someone enters the enclosure, and if the temperature in the enclosure feels lower than 10 degrees Celsius.  Multiple benches and garbage disposal units will add to your comfort.

The entire platform will be well lit, with lighting inside the canopy as well as on the platform.  And to enhance your feelings of comfort and security, the back of the platform is protected from the Highway 7 traffic by a barrier wall topped with a guardrail, and there are multiple security features including cameras and an emergency call button.

Last but not least, to help you stay oriented, wayfinding signage will show you where the buses will stop, and other features including the way to the crosswalk.

It’s hard to do our stations justice by written descriptions, so the best way to take a tour will be in person.  We’re looking forward to showing them to you, and will want to hear all your feedback!

planting for beauty and longevity

One of the wonderful new elements of the vivaNext streetscape is the number and variety of new plants that are being added, from the planters on the stations and in the median, to the trees and shrubs being planted along the boulevards and intersections.  The Landscape Architects, in conjunction with York Region’s Forestry Department, have worked long and hard on which plants will be included at each location.  Here’s what you’re going to be seeing planted along the rapidway corridor, and how they made their choices.

All the plant selections have been made with maximum survivability and sustainability in mind.  That means plants have to survive the urban conditions they’ll be surrounded by – with the main threat being the de-icing salt that needs to be used on the roads in winter.  Salt is toxic to many plants, so finding plants that can cope with having salt spray on their leaves and stems over the winter is a key consideration.  Plants also have to survive the wind and drought conditions that are part of being next to a roadway.  Another consideration for species selection concerns trees for planters under hydro lines.  In these locations, we need to find species with a maximum size and shape that will allow them to grow to their full potential, without needing to be pruned away from the lines.

Fortunately, York Region’s Forestry Department has had a lot of experience with the plants that thrive in the Region so coming up with lists of viable plants was straightforward.

Other considerations were related to the basic elements of design: shape, scale and colour.  We had clear overall design objectives to work with, consistent with the larger vivaNext aesthetic: the look was to be urban, stylized, and modular, similar to the look of our pavers.

Here are some images of our plants, including deciduous shrubs, evergreen shrubs for winter interest, hardy roses, ornamental grasses and perennials.

And to give them the best chance for survival, they will be planted in a special planting mix developed by the Region’s Forestry Department that will provide the optimum growing conditions.  Each tree will have a full 16 cubic metres of soil – that’s about the same amount as two dump truck-loads!

We’re looking forward to having people see the new landscaping, and we know it’s going to make a huge contribution to our goal of creating a more attractive, welcoming streetscape.  With the waving grasses and flowering plants, and shapely trees and shrubs, these public spaces will be more beautiful for years to come.

countdown

As we get closer and closer to the time when the Highway 7 rapidway will be ready for service, our teams are working hard to finish all sorts of little details.  With much of the construction complete, we’re now focused on the final stages of completion and testing, and then getting ready for handover, when the system is officially turned over to York Region and YRT, the system owners and operators.

Handover means just what it says – it’s the moment in time when a system is handed over to the owner for care and custody.  From that time going forward, a system – which until then has been the responsibility of the Contractor/Design Builder – becomes the private property of the owner, and anyone needing access to do any additional work needs to get the permission from the owner for access.

Because the formal handover is such a significant development, especially on a major infrastructure project like the vivaNext rapidway, it’s important to ensure everything is in perfect working order.  The various steps involved in commissioning, which is the testing period that takes place before handover, vary depending on what is being handed over.  For example, with the fare equipment, we make sure the ticket vending machine [TVM] prints properly.  With the traffic signals, once they’re programmed the permanent signals are turned on and each phase is tested individually, and all the push buttons are tested to make sure they work.

Streetlights are inspected to ensure all the wiring is according to the drawings; that the bases are level, and the power connections are all correct.  The teams go out at night to actually turn on the lights, to ensure all the lamps come on and nothing is flickering.  Lighting is an important safety feature for both pedestrians and vehicles.

Viva driver testing is completed to make sure drivers know how to use the rapidway, its signals, and the stations.

Every single detail is inspected through a visual walk-down and a list of the things that still need to be finished or perfected is created with items graded from most serious to least serious.

Once handover takes place, legal ownership and responsibility is transferred to the owner, and the Contractor/Design Builder’s warranty period begins, just the way it happens when a homebuyer takes possession of a new house.

Handover in this case means some elements of the rapidway, like the rapidway, stations, boulevards and planters, are transferred to the Region.  Others, like the sidewalks and streetlights are transferred to the local municipality to maintain.

Ultimately, everyone who has a stake in vivaNext wants to see it work as designed, to provide a reliable, efficient rapid transit system and beautiful streetscape.  Because, at the end of the day, the ultimate owners are the people who are depending on it to work well: the public of York Region and we all want this to be a system to be proud of.

Glossary of construction terms

Construction can be chaotic for the layperson with its oddly shaped machines digging, drilling and moving around dirt, concrete and other large items. It can be hard to understand what they’re doing exactly, but things can get even more confusing when construction terminology gets thrown around. To help anyone who might be interested we’ve compiled a list of our most often used terms, just for the fun of it –

Abutment A structure located at the ends of a bridge, where the bridge slab adjoins the approaching roadway.
   
Archaeological Testing/Assessment The examination of limited areas for the purposes of identifying historical artifacts. We do this work to meet the requirements of the 2007 North Yonge Street Corridor Public Transit Improvements Environmental Assessment, which identifies areas of potential archaeological interest along the Yonge Street corridor, so that we can ensure any important historical artifacts are identified before the roadway is widened for the rapidway.
   
Backfill Material used to replace, or the act of replacing material, removed during construction. Also, may denote material placed, or the act of placing material, adjacent to structures.
   
Bore Holes Drilling into the ground to bring up samples of earth for testing.
   
Boulevard A strip of grass between a sidewalk and a road, located above a curb.
   
Bridge Pier A supporting structure at the junction of connecting spans of a bridge.
   
Caissons A cylindrical concrete foundation that penetrates through soil to rest upon an underlying stratum of rock. Or the structural support for a type of foundation wall.
   
Canopy A curved glass and steel structure over a vivastation platform that shelters passengers.
   
Cast-in-Place A construction of forms filled with concrete at the final location.
   
Catch Basin A receptacle for catching water runoff from a designated area; usually a shallow concrete box with a grating and a discharge pipe leading to a plumbing or stormwater system.
   
Cofferdam A watertight steel enclosure from which water is pumped to expose the bottom of a body of water and permit foundation construction.

Daylighting The process of exposing buried utility lines to daylight.
   
Directional Drilling Drilling sideways under structures, roadways, streams, etc. to place pipes, utility lines without excavation and generally limited to less than 30cm in diameter.
   
Duct bank Groups of conduits designed to protect and consolidate cabling to and from buildings. Data and electrical cables are laid out within PVC conduits and bundled together; these groupings of conduit are protected by concrete and metal casings. Duct banks are often buried, allowing contractors to consolidate the wiring for a building into centralized underground paths.
   
Easement An interest in land owned by another that entitles its holder to a specific limited use.

The Growth Plan

York Region is growing and vivaNext is the plan to bring the next generation of rapid transit to service that growth. Funding has been granted for several projects within the plan, including bus rapid transit [BRT], a subway, a bus maintenance facility and bus terminals. But where does that plan start? In general, it starts with vision, professional expertise, time, money and a commitment to stick to the plan.

But to be more specific, like all really important initiatives, the starting point for a successful transit program is doing in-depth planning to assess the Region’s population trends, long-term growth forecasts, transportation and development patterns, and economic development goals.

The overall need for rapid transit and the specific projects that together make up vivaNext were first identified in the Region’s Transportation Master Plan, then thoroughly evaluated through a series of Environmental Assessments.

Consultations with approval agencies, such as conservation authorities and local heritage committees, as well as the broader community, including employers, ratepayer groups and chambers of commerce, also provided important input.

This multi-year planning process has involved many levels of professional expertise within and affiliated with York Region and our local municipalities, and is proof of our communities’ long-range stewardship to meet our future needs.

Once the planning is complete then the work of building the transit network begins. Work that requires a logical and disciplined approach, to identify which pieces need to be built first, forming the network’s backbone, and which components can come later. Construction also has to be carefully staged, to minimize the disruption to communities, businesses and travelers.

That logical progression has informed how we’re staging the construction of vivaNext, with the added complexity of planning for the greatest amount of connectivity between our network and the larger GTA transit network as it expands.

Our overall priority is to improve the transit network at every step, so that we all can benefit right away from having more transit choices and a welcoming streetscape.

All currently funded segments will be completed by the end of 2018. But that won’t be the end  – with vivaNext’s established success in delivering projects as planned, we hope to obtain new funding to complete the remaining segments of the network, including additional rapidway segments and the extension of the Yonge Subway to Highway 7.
