WATERFRONT REGENERATION BENEFITS

The following ten principles from the Urban Land Institute prescribe how to take advantage of the opportunities afforded at water’s urban edge, and to succeed in new development:

Transformations along urban waterfronts are a recurring condition in the evolution of cities, and tend to take place when there are major economic or cultural shifts leading to conflicting visions about the course of contemporary urbanity.

Waterfront redevelopments are long-term endeavors with the potential to produce long-term value. Endangering this for short-term riches rarely produces the most desirable results.

The aura of a city resides and endures along its waterfront allowing substantial changes to occur without inevitably harming its enduring qualities of place.

Despite undergoing periodic and at times quite rapid change, a waterfront maintains for its bordering city some inherent and unalterable stability.

Underused or obsolete urban waterfronts come alive (after industry has receded) they must become desirable places to live not just to visit and recreate.

The public increasingly desires and expects access to the water. This usually requires overcoming historic barriers physical, proprietary and psychological while persuading new investors that there is merit in maintaining that valuable edge

As valuable and often contested realms, urban waterfronts bring forth the opposing though reconcilable human instinct to preserve and to reinvent.

Even though a city’s waterfront serves as a natural boundary between land and water, it must not be conceptualized or planned as a thin line.

The success and appeal of land side development is intrinsically tied to the success and appeal of adjacent water uses and, of course, to the environmental quality of both the water and the shore.

Distinctive physical environments (characteristic of waterfront setting) can serve as an antidote to the homogenizing tendencies of modern development, providing a competitive advantage for a city in relationship to its region or rival cities.


Cities seek a waterfront that is a place of public enjoyment. They want a waterfront where there is ample visual and physical public access - all day, all year - to both the water and the land. Cities also want a waterfront that serves more than one purpose: they want it to be a place to work and to live, as well as a place to play. In other words, they want a place that contributes to the quality of life in all of its aspects - economic, social, and cultural.

BIRMINGHAM CANALS Birmingham has over 200 miles of canals constructed by various companies during the industrial boom in the 1900s. Due to decline in industry, the canals were abandoned through lack of use. In 1988, an urban design strategy was created to enable the delivery of a ‘visual identity at a pedestrian scale’ for the city. The canals have now been regenerated to provide a series of public open spaces.

IJBURG, AMSTERDAM Amsterdam is a city built on reclaimed land. Large areas are being redeveloped/ rehabilitated and new areas are being made on artificial islands. Ijburg is a development to the east of the city, which was enabled through a thorough planning process, government endorsements, community involvement etc to create an attractive island of housing, mixed-use development, cultural centres and new transport infrastructure.

According to Papatheochari (2011), Jones (2007) and Goddard (2002), (sourced via Umut Pekin Timur: Urban Waterfront Regenerations) the most pronounced benefits of urban waterfront regenerations are:

REPRESENTING NEW ECONOMIC REGENERATION OPPORTUNITIES FOR DECLINING INNER CITY AREAS

PROVIDING A RELATIONSHIP BETWEEN WATER AND THE CITY ATTRACTING TOURISTS NOT ONLY AT A REGIONAL LEVEL, BUT NATIONALLY AND INTERNATIONALLY

CREATING NEW HOUSING AND JOBS

ENCOURAGEMENT OF ECONOMIC INVESTMENT

THE IMPROVEMENT OF WATER QUALITY AND WATER ECOLOGY BY MEANS OF THE ADVANCED MANAGEMENT PROCESSES

THE PRESERVATION HISTORICAL AND LOCAL HERITAGE ALSO RE-USE OF HISTORIC BUILDINGS

PROVIDING OF OPPORTUNITIES FOR NEW USES AND ACTIVITIES

THE INCREASE IN REAL ESTATE PROPERTY VALUES

RESEARCH RIVER NENE

The River Nene is the tenth longest river in the UK, roughly 88 miles/142 km running north-east from Northampton to The Wash. The river passes through many historic market towns, listed heritage features, archaeological sites, and scheduled monuments. There is currently a strategy plan for the Nene Valley, which identifies the recreational and tourist offer of the area. The strategy aims to increase the connectivity not just between adjacent towns of the river, but between the towns themselves by improving access, investing in waterways, and creating destinations. With the study area adjacent to the river, a big emphasis should be put on its orientation, accessibility and character. Historically the site used to function as a timber yard with other industrial use, so access to the river was important for trade. The west side of the valley is seen to be a little more urban/industrial in its character, versus rural towards the east.

RESEARCH HISTORIC FLOODING

The River Nene carries a flow of about 150m3/s (cubic metre per second) in a 1 in 100 year event through Peterborough. The river drains a natural catchment of 1711km2 to Peterborough, and a further catchment of 556km2 giving a total catchment of 2267km2 to the Wash. The tidal flow is now mitigated at the Dog-in-a-Doublet sluice, built in 1936, 8km east of the site. Prior to this, the river was tidal adjacent to the site.

RESEARCH CONSTRAINTS

The constraints plan below shows that the project site was barely affected by the significant flooding events in 1947 and 1998. Approximately 10% of the site has been identified as Flood Zone 2 (1 in a 100 years) and approximately 6% of the site as Flood Zone 3 (1 in a 1000 years), located mainly in small areas of the site adjacent to the river. The associated water levels with Flood Zone 2 and Flood Zone 3 are 4.8m and 5.78m AOD respectively. (Source: EA via Peterborough Level 2 SFRA). The water level fluctuates between 3.37m and 4.45m AOD.

Nature Improvement Areas (NIAs) were chosen by selection to create a resilient ecological landscape network. They are identified as areas with the opportunities to establish and improve the ecological environment, by enhancing and connecting existing wildlife and creating new habitats. It is part of a shared vision run by partnerships of local authorities, local communities, landowners and conservation organisations, with funding by the Department or the Environment, Food and Rural Affairs (DEFRA) and Natural England.

UK BIODIVERSITY ACTION PLAN (BAP)

This report reviews priority species and habitats based on a criteria of international importance, rapid decline and high risk, in order to create a plan of action in the UK.

For more information about the UK Biodiversity Action Plan visit http://www.jncc.gov.uk/page-5155

Overall Goal To conserve and enhance biological diversity within the uk and to contribute to the conservation of global biodiversity through all appropriate mechanisms. Underlying Principles 1. Where biological resources are used, such use should be sustainable. 2. Wise use should be ensured for non-renewable resources. 3. The conservation of biodiversity requires the care and involvement of individuals and communities as well as Governmental processes. 4. Conservation of biodiversity should be an integral part of government programmes, policy and action. 5. Conservation practice and policy should be based upon a sound knowledge base. 6. The precautionary principle (see glossary) should guide decisions.

BIODIVERSITY THE UK ACTION PLAN

Objectives for Conserving Biodiversity 1. To conserve and where practicable to enhance: a) the overall populations and natural ranges of native species and the quality and range of wildlife habitats and ecosystems; b) internationally important and threatened species, habitats and ecosystems; c) species, habitats and natural and managed ecosystems that are characteristic of local areas; d) the biodiversity of natural and semi-natural habitats where this has been diminished over recent past decades. 2. To increase public awareness of, and involvement in, conserving biodiversity. 3. To contribute to the conservation of biodiversity on a European and global scale.

Rivers in the UK as a habitat are identified in the BAP as having international obligations. “Rivers have been adversely affected by many different anthropogenic pressures, and in many instances the risks remain; some are reducing but others are increasing.”

“Rivers support a wide range of key species of vertebrates, invertebrates and plants, including: otter, Atlantic salmon, river, brook and sea lampreys, spined loach, bullhead, allis shad, twaite shad, white-clawed crayfish, freshwater pearl mussel, Southern damselfly and floating water-plantain.” 33

CAMBRIDGESHIRE AND PETERBOROUGH BAP

“Biodiversity is the variety of life, the WOW factor, the “Wealth of Wildlife” that surrounds us. Nature provides us with resources, e.g. food, medicine, materials, and also with ecological services, such as flood protection and clean air. Biodiversity also has aesthetic and cultural value for recreation and enjoyment.” Vision for 2016 • • • •

Biodiversity is a cross-cutting issue of high importance and an integral component of environmental sustainability Cambridgeshire and Peterborough habitats and species are protected, enhanced and sensitively managed within a changing climate and under a growing human population Key habitats and species are increasing within their natural ranges Biodiversity is valued and enjoyed by everybody in Cambridgeshire and Peterborough

NENE WASHES

Peterborough Biodiversity Policy Policy LP28: Landscape and Biodiversity “Development which is likely to have an adverse effect on a designated site, including harm to habitats or species of principle importance, will only be permitted where the benefits to development demonstrably outweigh the dis-benefits... In all cases a net gain in biodiversity should be achieved.” Through the development management processes, management agreements and other positive initiatives, the council will: • •

34

Aid the management, protection, enhancement and creation of priority habitats, including limestone grasslands, woodlands and hedgerows, wet woodlands, rivers and flood meadows; Promote the creation of an effective, functioning Green Grid throughout the district, consisting of wildlife corridors and stepping stones that link to green infrastructure in adjoining local authority areas; Safeguard the value of previously developed land where it is of significant importance for biodiversity;

Planning permission for development will only be granted if the proposals make provision for: (a) the retention and protection of trees and other natural features that make a significant contribution to the landscape or biodiversity value of the area, provided this can be done without compromising the achievement of good design for the site; and (b) new landscaping and biodiversity features as an integral part of the development, with specific attention to wildlife habitat creation, including new tree, shrub and hedgerow planting appropriate to the location; and (c) the protection and management of existing and new landscape, ecological and geological features during and after construction, including the replacement of any new trees or plants which die, are removed or become seriously damaged or diseased; and (d) where necessary, the protection and enhancement of any aquatic environment within or adjoining the site, including water quality and habitat. For riverside development, this includes the need to consider options for riverbank naturalisation. In all cases regard should be had to the council’s Flood and Water Management SPD.


WET WOODLANDS

The habitat of wet woodlands has declined nationally due to challenges concerning agriculture, industrial development, residential development, lowering of water tables and flood prevention. In the UK and especially Cambridgeshire and Peterborough, wet woodlands are a priority habitat for a range of priority species, such as: otters, bats, Marsh Warblers, Spotted Spycatcher and Song Thrush. Wet Woodland is a combination of many elements of other ecosystems. It can include scrub planting, reeds, marginals, aquatics, and log piles to provide a range of habitats. Plant species mainly consist of Alder, Elm, Birch and Willows.

BURGESS PARK WET WOODLANDS

Targets • • • • •

Maintain the current extent (estimated to be 276 ha) of wet woodland in Cambridgeshire and Peterborough. Maintain at least the current condition for wet woodland within SSSIs & County Wildlife Sites in Cambridgeshire and Peterborough. Achieve favourable or recovering condition for 90% by area of wet woodland within SSSIs & County Wildlife Sites*, by 2010 (95% by 2015 and 98% by 2020). Restore 20 Ha of wet woodland on existing sites, by 2010. Create 50 Ha of wet woodland on improved grassland, arable, or former minerals extraction sites, on, adjacent to and linking existing sites, by 2010, 100 by 2015 and 150 ha by 2020 (there is long-term potential for 300+ ha). Enlarge and link existing site where possible.

GENERAL ARRANGEMENT

Gatic Slot Drain - 3m Channels (100mm width)

This general arrangement plan shows the diverse materials and treatments used in the waterfront area of the site. Raising the main route along the water to +5.0m AOD mitigates any flooding impact at 1%. The soft edges, designed to flood, run along the waterfront softening the edge of the site and creates an interesting transition between the site and river. Consideration is taken to accommodate suitable planting for these areas, including enhancing the existing Birches on site by planting a buffer of riparian planting.

The ornamental terraces hold a diverse range of plants for seasonal and visual interest, contrasting with lines of River Birch to reflect the character of the waterfront. The soils on site are mainly clay, which is rich in nutrients and can accommodate a range of planting. Treatment to the soil, such as mixing in organic matter and mulching the surface will help with conditions.

WATERFRONT SLOPES + LEVELS

Although the site is relatively flat, it is constrained on the west side due to the merging levels of the bridge on London Road. Currently there is a hard edge to most of the west side making it inaccessible, and the main vehicular entrance is on a very steep gradient. To make the site more accessible and respond to these constraints, the levels across the site are proposed to be altered to provide a smooth transition. This will be achieved through varying solutions, including retaining walls, gabion walls and DDA compliant slopes. Providing these innovative level changes across the site will achieve function and interest, as well as being responsive to challenges with designing in a floodplain.

MAINTENANCE MAINTENANCE + MANAGEMENT

Reedbeds are primarily made up largely of a Phragmites australis (common reed) – a perennial and flood-tolerant grass [Hawke and Jose, 1996]. Reeds and associated planting attract a diverse range of species which include the Bearded Tit, Marsh Harrier, Harvest Mouse, and the Bittern.

“Reedbeds are dynamic ecosystems; temporal and spatial variation in the habitat is key to maintaining a high diversity of flora and fauna.” (RSPB) Planting reedbeds on the waterfront is a suitable solution for:

Characteristics of land required for reedbed creation:

• Softening the edge of the river

• Reliable and adequate water supply

• Flood mitigation

• Control of water levels (ditches, sluices)

• Enhancing / creating habitats

• Level or shallow gradient

• Promoting human interaction / social profile of wildlife within the city

• Access for management

• Purification of water

Management Without management, a reedbed will dry out and turn into woodland. As the proposed reedbed is planted on a slope and containing areas of open water, different habitats are created due to reeds being above or below the water levels. Reasons to manage reedbeds: • Use of reed for commercial purposes • Stimulate production of new buds • Provide temporary habitats during cutting season • Controlling the spread of reed planting into open water LONDON OLYMPIC PARK WETLANDS

54


OUSE FEN WETLANDS

The greatest cause of failed establishment of reeds is competition form other plant species. This can be controlled by keeping a third of the reeds above water and use of herbicides or manual removal. Manual removal equals higher maintenance, but for a small area has proved to be the most successful/practical method in reedbeds in Rutland Water. As suitably proposed, the reeds will be planted from plugs transferred to site to increase its chances of success. During establishment, fencing will be required to protect the reeds from any manage caused by geese/other fowl. The fencing should be made of untreated timber, constructed 50mm into the silt with a minimum of 1.0m height. The contractor is responsible for maintaining the fencing during the establishment phase and should last a minimum of two years.

Water Levels Managing the water levels for a reedbed in very important, as many fail due to drying out from a build up of reed litter. The RSPB advice that it is most suitable to maintain a natural water level in winter, and dropping to a lower level in the summer. Care should be taken not to only maintain the reed planting, but also not to harm any key species within the reedbed.

Cutting Cutting should be done to maintain reed dominance in the non-growing season. Water levels should be lowered for this, with a gradual increase post-cut as to not slow down (or kill) the reed planting. As the reed planting is one-half to a two-thirds at the water level, brush cutters are the advisable tool for cutting. Keeping to Peterborough’s aspiration to be the environmental capital of the UK, the reed cutting should be re-used either on-site in the Wildlife Zone, or used for horticultural purposes off site i.e. local gardens, allotments, farming. EXAMPLE OF BRUSH CUTTING

55


Wet Woodland Management Wet woodlands are very species-rich. General guidelines (Wildlife Trust) state that choosing not to undertake any management work is an acceptable form of managing wet woodland as these conditions encourage the wildlife. To increase wildlife, coppicing Alders etc. are recommended. Retaining some standard trees within coppiced areas reduces the rate of growth of the coppice stools and retains a diverse woodland ground flora. Willows can be pollarded (pruning the upper branches) every two to three years to increase the levels of light to the ground. Any felled trees can be re-used as habitat for insects and birds, similar to the log piles on site. Natural regeneration of native species should be encouraged where possible. Thinning or felling selective non-native and invasive species is advisable. Source: Wildlife Trust

Floating Booms or Coir Rolls To ensure the protection from the Rivers current, and to help encourage and establish plant growth, a ‘floating boom’ should be firmly anchored to the river floor, or use of coir rolls to help establish.

56


Log Piles and Dead Wood Deadwood has a highly positive impact as part of a woodland habitat. Many wood-boring species and those requiring shade/damp (reptiles) would thrive in this sort of habitat. Combined with the proposed locations shown in the General Arrangement drawing (page 48), dead wood running into water provides a habitat for bird roosting and fishing perch for kingfishers. [Baines and Smart, 1991]

COMMUNITY INVOLVEMENT

Community Engagement Community engagement is very important to consider as a part of any development scheme. It is proven that people feel a sense of ownership when they have had some sort of influence or engagement in the process. Source: Project for Public Spaces Local schools could be involved by learning about reeds and helping to grow their own plugs to be used on site. Conservation volunteer schemes could also contribute to the management of planting on-site, alongside the open public access to the urban allotment space to the west of the Wildlife Paradise. With the proposed variation in plant species and habitats, the Wildlife Paradise would also prove useful as a facility for educational purposes for local schools and colleges. 57
