Walthamstow Wetlands Briefing

Walthamstow Wetlands offers a once in a lifetime opportunity to maximise the environmental and regeneration benefits of this unique open space. Our shared vision is to open up Walthamstow Reservoirs to wider public access as an urban wetland centre and nature reserve in the heart of the East End of London. We want this unique landscape, constituting 178 Ha (440 acres) of space, to become a valued part of the life of local people and a popular regional visitor destination. The reservoirs, located just north of the Olympic Park and central to the Lee Valley Regional Park, constitute the single largest man-made body of water in London. They are recognised as being of international, national and local importance for wildlife, are the largest fishery in London and remain the principal source of water supply to the city. Termed, Walthamstow Wetlands, this 'wild space', is surrounded by dense urban settlements containing some of the most deprived communities in the UK, with deficiency of good quality open space. Almost half a million residents live within two miles of the area (people living in 13 surrounding Boroughs can reach the site in 45 minutes by public transport). Yet, physical, visual and psychological access to Walthamstow Wetlands (this includes the reservoirs and adjoining waterways, marshlands and parks making up 400 Ha (988 acres) in total) is disjointed and unwelcoming, creating a culture of severance between people and landscape which has lasted for over a hundred years.

This project, which includes a 'Water and Life, visitor centre, will open up this exceptional blue/green asset for local people to experience and enjoy, contributing to the quality of life and health and wellbeing of citizens. This links into our and the Mayor's 'convergence' ideals, helping to support sustainable communities in this part of London.

Unlike the Olympic site, and park development in the Lower Lea, we do not have to build a park as much of the infrastructure in place. This means that with relatively little cost and through modest interventions, it will be possible to deliver a significant asset to London. The project cost is estimated at around £10m which, compared to similar projects elsewhere (such as the Barnes Wetland Centre, which we understand cost in the region of £30M to deliver) is good value for money. Overall, the Business Plan (CBA April 2010) for the project assumes there will be 100,000 visits/year to the 'Water and Life' attraction, and 250,000 visits/year to Walthamstow Reservoirs overall.

The proximity of Walthamstow Wetlands to the Olympic park means that it can be showcased as part of a striking and influential legacy. Walthamstow Wetlands will allow access to nature, biodiversity and wildlife habitats, which will add value to the offer of the Olympic park, creating an exceptional overall leisure, environmental and educational resource.

Walthamstow Wetlands will play an integral role in the transformation and renewal of this part of the Lee Valley. The delivery of a more attractive environment, improved access to exceptional blue/green assets will help boost confidence in the area, helping to attract investment, particularly at Opportunity Areas in Blackhorse Lane, Tottenham Hale and the North Olympic Fringe. The sustainable regeneration of East London depends on easy access to quality open spaces as well as homes and jobs.

The Project

The project will build on key features of the reservoirs as · the principal source of water supply; · a recognised wildlife habitat and striking waterscape; and, · important industrial landscape,

to create a distinctive urban wetland centre where people can access nature and come into contact with wildife in the midst of a densely populated and urbanised part of London. The project will focus on improvements to (i) biodiversity and wildlife habitats, (ii) connectivity and public access and (iii) animating the landscape through facilities that attract public participation. Education is one of the key pillars of the project offering the opportunity to learn about nature conservation, sustainability, water quality and supply and the rich industrial heritage of the area.

The project includes:
* Restoration of the disused Marine Engine House (possibly the Coppermill), to house a 'Water and Life' visitor interpretation centre and educational resource, café and amenities; associated outdoor space for learning and interpretation which allows close contact with nature and habitats.
* Improved public access into and legible routes through the landscape, especially improved east/west links to reconnect the reservoir site with surrounding urban communities; improved links to the Olympic Park to the south and the adjoining parks, marshes, nature reserves and waterways to create a single, holistic landscape that offers a series of complementary and contrasting experiences for the visitor.
* Environmental enhancements and restored and improved biodiversity and wildlife habitats.
* A culture of engagement in the process of project delivery through educational programmes, heritage walks, encouraging volunteering, and an annual river festival.

Whilst the reservoirs form the core of Walthamstow Wetlands, the adjoining waterways, marshlands and formal parks of the Lee Valley Regional Park form an integral part of our vision to create a holistic and integrated landscape experience. The project will result in a reinstatement of connectivity and flow between these spaces, and create legible connections with the Olympic Park, creating an exceptional landscape asset, which sits at the heart of the Lee Valley Regional Park.

In addition, the surrounding waterways offer the opportunity to create areas of waterfront animation at Springfield Marina, Tottenaham Lock and Stonebridge Lock, through cafes, boating, canoeing and amenities/facilities that attract public participation and activity.

Walthamstow Wetlands remains an industrial landscape. This part of the Lee Valley offers a glimpse into the role the Lee Valley has played as the power house of industrial innovation and in the supply of energy, water and goods to support the growth of London. Peppered throughout the site are a number of historic buildings and heritage features associated with water supply and filtration which will be profiled. The project will also create links with nearby heritage sites, including the Pump House Museum, Beam Engine House and Waterworks Centre and Middlesex Filter Beds. These sites have benefited from support from Heritage Lottery Funding and in the case of the Pump House, support through Section 106 and peppercorn rent arrangements with LBWF. Walthamstow Wetlands will result in increased footfall for heritage sites, through improved pedestrian links and co-ordinated marketing and promotion.

Who Will Deliver

A partnership of the following agencies has been formed to deliver the project, with LB Waltham Forest providing the lead and coordination role. ThamesWater Lee Valley Regional ParkAuthority Natural England Environment Agency English Heritage British Waterways LB Haringey LB Hackney Design for London/GLA

As well as public sector agencies joining forces in the delivery of the project, the partnership will seek private sector investment and the support of the wider community, encompassing 'Big Society' principles.

Immediate Actions: The project is likely to take 5-10 years to deliver. Whilst funding is being sought, partners are keen to implement some early actions such as opening up the site as part of Open House in September, introducing interpretational signage and waymarking and promotional activity. A bid to Heritage Lottery funding is being developed.
