White Hart Lane - Environmental Improvements Today s event is one of a number of information sessions held in the area, to ensure that local people are informed about the projects planned for White Hart Lane and to give you the opportunity to comment on the proposal. The designs and plans presented reflect conversations that have taken place with local residents, community groups, businesses and land owners. About White Hart Lane White Hart Lane is a place where people live and work, a place where children grow up. White Hart Lane has a community of independent shop keepers and businessess and has a rich history. There is an invisible river beneath the pavement and there is the potential to be a much greener place. White Hart Lane is a strategic route; one of the few east west roads that can be used by high sided vehicles because of the low railway bridges on surrounding roads. However an over emphasis on the use of the road by cars has undermined the environmental quality of the neighbourhood for people walking, using public transport or cycling. In addition the junction with the High Road is an accident spot and the pavements throughout are narrow and are poorly designed for people with mobility issues. What we are trying to do The aim of this project is to make White Hart Lane more attractive and welcoming, to make it a better place to live, to support the existing shops and to encourage more businesses to come to the area. The illustrations on the following boards show early design principles for altering the junction, widening the pavements and traffic calming, sustainable drainage, greening the street and the proposed materials. Once we have the final survey information and have gathered feedback from you, the community, businesses and other partners we will finalise the design. North Tottentham is Changing The improvements to White Hart Lane are part of the much bigger plans for major investment and regeneration in the area that includes: The High Road West Development - the building of a sustainable neighbourhood to the north and south of White Hart Lane with over,000 new homes set around a new square, library and learning centre and existing workspace as part of new leisure hub. White Hart Lane Station - the 1m+ refurbishment will make the station safer and more accessible with a new entrance and improved access to platforms. Plans for the regeneration of Northumberland Park and Love Lane Estate combined with the new Tottenham Hotspur Football Club Stadium development will improve the health, wellbeing and prospects for local residents, including providing health centres and schools; create thousands of new jobs; and it will deliver high quality community facilities at the heart of the area.

35 White Hart Lane - Environmental Improvements to Reduce the Impact of Traffic White Hart Lane now White Hart Lane is well served by public transport with the overground station and an extensive district network of bus routes that converge in the area. In addition, the Cycle Super Highway 1 is situated 800m south of the station, connected to the site via the local cycle network. However, although traffic numbers on White Hart Lane are relatively low outside peak hours, the road is a hostile environment for pedestrians, people accessing public transport and cyclists. Traffic regularly exceeds the 0mph speed limit and the road is congested due to the complicated interdependent traffic lights at the High Road junction. This results in an increased risk of collisions and high levels of pollution. In a Ward where many people don t own cars this disproportionately impacts the people who actually live here, as much of the traffic is passing through east to west. How Can White Hart Lane Become a Better Environment for People? The key aim is to accommodate the traffic but not to let it dominate. This will be achieved by two principle design moves: 1.Reduction of the width of the carriageway so cars have less room and pedestrians have more room.. Inclusion of features which the motorist has to negotiate in stages, so they pay attention to what is immediately in front of them and are less likely to speed. The carriageway width is reduced from 4800mm to 3400mm, the difference is shown in the drawings below, in addition a central pattern runs along the centre of the road giving the impression the road is narrower than it is. This width was agreed with Transport for London who run the buses, the emergency services, to ensure ambulances have room to pass, and Haringey 14%, the local access group. Reducing the carriageway will increase the width of the pavement all along White Hart Lane. At intervals along the road we will raise the road up to the same level as the pavement. In these sections the road is treated with a contrasting material. The combination of the ramp up and down and the visual patterning reduces the tendency to speed and keeps traffic within the 0mph limit.

Widening of the pavement on both sides of White Hart Lane at the High Road junction to give more space for pedestrians. The red dashed line shows the width of the existing pavement. Reducing three lanes to two will give the left turn lane from the High Road to White Hart Lane a wider lane for turning vehicles so they don t mount the pavement or pull out into the oncoming traffic lane. Traffic lights programmed to give pedestrians longer crossing times with larger islands in the centre of the road. Phasing will also reduce congestion of traffic heading east from White Hart Lane

White Hart Lane - Environmental Improvements Sustainable Urban Drainage Sustainable Urban Drainage Strategy What is Sustainable Urban Drainage (SuDS) SuDs is the practice of managing surface water by designing ground conditions to act like a sponge, holding water, filtering it and releasing slowly to rivers or the sewer to protect them from pollution and flooding. Since Victorian times rain has been seen as a problem rather than a vital resource that supports our city s green spaces and wildlife. Normally rainfall is directed as quickly as possible to drains. As we build more and more hard surfaces, during heavy or long storms the rain runoff to drains can overwhelm both the sewer system and rivers and cause flooding Rain garden to catch the water flowing off the road and act as a sponge to slow, cool and filter out We want to manage rainwater as close as possible to where it falls and help the rainwater soak though to the layers below. Paving slabs will be laid with small gaps between them. The gaps are filled with pollution-cleaning grit through which the water drains to the layers below which act as a sponge slowing the flow of the water into the Why should we have SuDS Rain garden layout on the south east side of White Hart Lane How are SuDS part of the WHL design Moselle. This helps improve the quality of the water that will eventually flow into the Moselle River. SuDS and Rain Gardens Although it is possible to have permeable roads using a special surface, it is very expensive. The proposed solution is to drain the rainwater What happens if we don t have SuDS running off the road surface into road side bioretention rain gardens. Directing rainwater to drains does not just cause flooding. Rain runoff The water runs into the rain gardens where it soaks through special from roads, pavements and roofs discharged into rivers causes soil, grit and gravel filtration layers to remove pollutants and is stored environmental damage in two ways. Firstly, runoff from urban areas in these layers before being released slowly to the Moselle. In smaller contains petrochemical and heavy metal pollutants that harm or destroy storms most water will be soaked up by the soil, soak into the ground wildlife in rivers. Secondly in warm weather, our roads and pavements below or be used by the plants in the rain gardens. Rain gardens are absorb heat from the sun and if it rains the rainwater is heated up. The planted with plants and trees that tolerate getting soaked from time to warm water that flows into rivers holds less oxygen which suffocates life time so rain gardens also make the streets look greener. A section through the WHL pavement and road showing how rain falls on the road is washed into the rain garden, the pollutants are filtered out and the cool and cleaner water then enters the Moselle culvert. in the river. the pollution before letting the run off into the Moselle culvert Natural rock along the edge of the rain garden marking the route of the Moselle River Permeable grit jointed paving, rain can pass through to soak into the layers of ground beneath. Fish in the Lea River killed by a summer downpour of pollution and depleted the oxygen. The Moselle River before it flows underground into White Hart Lane showing a fungus that lives on sewage. Water running off the road into a rain garde A section through the road, rain garden and pavement Another cause of environmental damage is through domestic pipe Will the SuDs on WHL entirely prevent flooding and pollution and why misconnections. Because our rainwater is hidden in pipes that doesn t everywhere have SuDS disappear underground, people frequently connect foul water pipes (toilets, sinks, dishwashers, etc) into the rainwater pipes. This means that instead of sewage flowing to a treatment plant it discharges directly into our rivers killing wildlife. A section through the pavement showing the granular build up that acts as a sponge New planning laws require that all new developments have SuDS. What is more difficult is fitting SuDS into roads that already exist. Rain gardens and permeable drainage need space underground for layers of grit to act as the sponge. This underground space is often full of pipes carrying water, gas, electricity and internet cables. These pipes have to SuDS and the Moselle be protected from the rainwater and from the roots of trees, so a rain The Moselle river is the watery heart of the proposed development area garden cannot be directly above where pipes are running under the and gives White Hart Lane its distinctive curves.

White Hart Lane - The Materials The proposed materials for White Hart Lane are durable and easy to replace. The street furniture and lighting design will be part of the next stage of design. 1. Permeable, grit jointed, artificial stone flag stone paving. Permeable, grit jointed, artificial stone block paving where cars overrun junctions 3. Granite kerbs to pavement and rain gardens 4. Natural stone on edges of rain gardens to mark the route of the Moselle River 5. White road markings or imprinted asphalt on the raised tables and centre line.. Asphalt 4 1 3 5 William Street Example of a blended crossing where a side street meets the main road, the crossing is raised to remain at the same level as the pavement and is paved in a similar material. Example of a contrast in the colour and surface materials of the road with a central strip as a way to slow the traffic. Conventional road markings used in an unconventional way. A similar approach is proposed to visually break up the linear dominance of the road and so slow the traffic, especially on the crossings.
White Hart Lane - Environmental Improvements - What do you think? Would wider footpaths encourage you to walk more? Would increasing the number of crossings make it safer for you to cross the road? Would you feel comfortable crossing at a courtesy crossing, this is where the road is at level with the pavement and cars go up a ramp, like a speed bump, to slow them down? Would replacing the existing zebra crossing with more courtesy crossings be better or worse? Would a narrower road with slower moving traffic encourage you to cycle? What s your favourite idea of all the ideas we ve suggested? Do you feel that greenery, like that proposed, is important in a street? Would you like to see more schemes like this? What else should the designers be thinking about? What else are you thinking about in terms of the future of the street and the area? Please leave your comments on Post It Notes on this or other boards and/or talk to a member of the design team Next Steps The illustrations on these boards show early stage design principles for altering the junction, widening the pavements and traffic calming, sustainable drainage and greening the street and the material palette. Once we have more survey information about the location of underground pipes and have completed the engagement including your feedback we can finalise the design.
