Remediation of site and erection of a detached dwelling with associated landscaping works (comprising amendments to PA 12/01053/B)

Foxdale Local Plan 1999 Policy F/P/E/2

## 2.17 F/P/E/2 - POLICY In areas where there is a known risk of heavy metal pollution (see paragraph 2.2i), the following guidelines must be applied when a development is proposed: i. any development proposal must be accompanied by a full site investigation including both geotechnical and geochemical reports. ii. planning applications should address the best practical options for dealing with any contaminated fill either by removal to an approved site or by isolating it in situ. iii. where, for historical reason mine spoil is existing within a development and it is unrealistic to remove/cap it, then adequate landscaping should be specified. This may include a low-cost solution of revegetation with indigenous species provided that the Department can be satisfied that an adequately stable surface can be created. This is particularly important where slopes in spoil are adjacent to stream courses and in such cases the Government may wish to enter into a joint scheme to obtain other benefits for the community such as an access, nature trail or river bank stabilisation programme. If possible, any future landscaping scheme should include an area of impeded drainage in the hope that nature can be assisted to re-create the varied and valuable plant community previously existing and including northern marsh orchid Dactylorchis and Adderstongue Fern, Ophioglossum Vulgatum. iv. where proposals contain existing or proposed slopes made or cut into toxic fill/mine waste adequate attention must be paid to slope stability, likelihood of gullying or other threats which may mobilise toxic materials to the environment. v. planning applications should show how any toxic fill is to be prevented from being mobilised both during the course of development and afterwards. vi. surface and stormwater drainage must be fully specified in plans where the land contains toxic fill/mine spoil. The general principle will be to keep surface waters and subsurface drainage away from the fill where practical. Thus drainage from roofs and tarmac/concrete must be routed through solid-walled pipes to the stream network. vii. if possible schemes should be value-added in environmental terms: for example where field drains carry water into an adjacent area of spoil the developers should be encouraged to construct interceptor drains to avoid water entering spoil beneath the development. viii. no soakaways will be permitted in these areas. ix. plans which show proposed open space (grassed areas, gardens, etc.) over toxic waste should show in adequate detail how toxic material is to be isolated from both exposure at the surface and the ingress of drainage water. This will normally mean either the use of clay or installation of a membrane barrier. x. no bare ground, either as open space or trackways, made of spoil or toxic waste should be permitted. Where activities are likely to cause wear to the surface then those areas should be capped with an inert cover to a standard specification. xi. a condition may be attached to any planning approval granted such that adequate aftercare/landscaping is undertaken. NOTE: Further to the Government obtaining other benefits from the development, such as a nature trail, the Manx Nature Conservation Trust may be of assistance in terms of practical land management to conserve and enhance the habitats and their constituent flora and fauna, production of a nature trail, provision of interpretation boards leading guided walks and field study/educational courses, giving talks and slideshows to the local community and other groups.

protection of the countryside

presumption against development

Area Plan for the East sets out locally-applicable means for implementing the policies set out in the Isle of Man Strategic Plan 2016. In that Strategic Plan, we find the Environment Policies. Environment Policy 1 states: The countryside and its ecology will be protected for its own sake. For the purposes of this policy, the countryside comprises all land which is outside the settlements defined in Appendix 3 at A.3.6 or which is not designated for future development on an Area Plan. Development which would adversely affect the countryside will not be permitted unless there is an over- riding national need in land use planning terms which outweighs the requirement to protect these areas and for which there is no reasonable and acceptable alternative. Maintaining the purpose of this Area Plan as a means of implementation, there is some further direction to be found in the Strategic Plan, at paragraph 7.2.1: 'Whilst landscape and coastal change is inevitable, and in some cases desirable, the emphasis must be on the appropriateness of this change and the balance or equity between the needs of conservation and those of development. The primary goal must therefore be to respect, maintain and enhance the natural and cultural environment including nature conservation and landscape and coastal quality, and ensure its protection from inappropriate development.' Given the comprehensive nature of the Isle of Man Strategic Plan's Environmental Policies, only a small number of additional Proposals and Recommendations are necessary. In order to produce an implementable Area Plan for the East it is necessary to recognise those statutory desig nations and strategies which whilst having an Island-wide scope are highly relevant to the protection of environments within the Plan Area. An example is the UNESCO Biosphere status afforded to the Isle of Man. Island-level strategies identify crossborder issues and take account of the cumulative impacts of human engagement with nature. Area Plan Objectives i. To protect, conserve and enhance the natural and cultural environment of the plan area and promote biodiversity. ii. To improve the function, usability and provision of our green infrastructure and public spaces by providing a network of green spaces and features which are connected and where possible, accessible to the public. iii. To manage and improve flood risk and improve drainage conditions. iv. To support the working countryside and its custodians in maintaini ng a sustainable rural economy. Area Plan Desired Outcomes i. Where approved, d evelopment will be ecologically sustainable and designed to protect and where possible enhance biodiversity as well as mitigate and adapt to the effects of climate change. ii. The Green Infrastructure network will be established and fostered, connecting people with nature in a way that achieves the best shared outcomes for the urban and natural environment. iii. Statutory and non-statutory designations will continue to provide protection to the most important and most vulnerable cultural assets, habitats and environments in the plan area. iv. Beyond the towns and villages, the area as a whole will retain its landscape setting including its important visual interaction with the central uplands, central valley, coast and marine environment. Natural Environment Proposal 1 The Department supports the protection, creation and improvement of green infrastructure in the East, particularly in those locations which have the potential to be part of a Green Infrastructure Network. Applications for development must take into account any approved Government Green Infrastructure Strategies, but in any case, must identify how development proposals intend to contribute to the long term provision of a network of connected green spaces. UNESCO Biosphere In 2017, the Isle of Man became the first ever entire nation to achieve UNESCO Biosphere status. Project partners pledge to take steps to protect natural resources, develop the economy in a sustainable way and promote outstanding living landscapes. UNESCO Biosphere Reserves are established to connect people and the economy with nature, wildlife, culture, heritage and communities. Biosphere Reserves have three functions: Conservation: to contribute to the conservation of landscapes, ecosystems, species and genetic variation. Development: to foster economic and human development which is socio -culturally and ecologically sustainable. Logistic support: to support demonstration projects, environmental education and training, research and monitoring related to local, regional, national and global issues of conservation and sustainable development. The Isle of Man Biosphere is zoned into six areas . Examples of all of these can be found in the Eastern area: Terrestrial Core areas, Marine Core areas, Terrestrial Buffer zone, Marine Buffer zone, Terrestrial Transition areas and Marine Transition areas. There is some overlap with The Isle of Man's First Biodiversity Strategy 2015-20

Pollution-sensitive development

Environment Policy 24: Pollution-sensitive development will only be allowed to be located close to sources of pollution where appropriate measures can be taken to safeguard amenity. 7.20 Contaminated Land 7.20.1 Contaminated land on the Island is typically as a result of the legacy of past industrial and chemical land uses. Perhaps the most notable sites are land areas associated with former mining practices and it is not uncommon for such sites to be close to residential areas or watercourses which can be detrimentally affected by such contamination. Foxdale is a prime example of a former mining village, which largely specialised in lead mining during the 19 th Century under the control of the Isle of Man Mining Company, and physical evidence can still be found of important archaeological remains. A number of studies have revealed varying degrees of contamination across Higher Foxdale, much of which still requires reclamation from heavy metal contamination. It is recognised, however, that some of the former mining areas host a variety of rare plants which may have ecological value. (1) Environmental Impact Assessment: A Guide to Procedures. Department of the Environment Transport and the Regions (2000). 7.20.2 The practice of reclaiming contaminated land and bringing it back into beneficial use is supported, whether it be suitable in the end for open space or residential development or as deemed appropriate in the Area Plans. It is important that however former contaminated land is utilised, both health and property are safeguarded. Detailed surveys may be required to identify the extent of contamination and how contamination problems can be overcome. On sites where the Depar tment has no control, the developer will have responsibility to ensure that any development site is free of contamination which may constitute a hazard to occupiers or potential users of the development or land. Furthermore, precautions will be essential to ensure that contaminants cannot escape from the site which may cause airborne or waterborne pollution or pollution of nearby land.

Contaminated land

loped land is an important element in achieving regeneration and sustainable development objectives and to improve both the built and living environment. This is supported by paragraph 7.20.2 and Environment Policy 26 of the Strategic Plan. Development proposals on contaminated and/or unstable land, or where previous land use may indicate some level of contamination, must include an assessment of the extent of contamination and/or instability and any possible risks. Transport and Utilities Introduction This Chapter focuses on Transport (roads, public transport, cycleways, footpaths) and Utilities (energy, telecommunications, water supply, sewerage drainage and electricity). This Plan addresses infrastructure issues within distinct C hapters but it is impossible to plan for different kinds of infrastructure in isolation. The work undertaken to support this plan has included comprehensive site assessments looking at all aspects of development and needs in terms of supporting infrastructure, as well as scenario testing work which looked at broad development patterns and the implications on infrastructure as a whole. Issues relating to roads and utilities are often referred to as grey infrastructure and were discussed in the scenario testing work in these terms. Ahead of sections on ' area plan objectives' and 'area plan desired outcomes' in this Chapter, there is a brief discussion of two important long term infrastructure strategies which set the broad context for the preparation of the Area Plan for the East. This Plan incorporates the objectives of both the National Infrastructure Strategy and the Harbour Strategy and is in support of their desired aims. Strategic Plan Implementation - Transport and Utilities The Isle of Man Strategic Plan contains specific strategic policy in respect of transport and other grey infrastructure. The Chapters on Strategic Objectives and Strategic Policies state that development needs to: • optimise the use of previously developed land; • use sites efficiently; • utilise existing and planned infrastructure, facilities and services; • minimise journeys by private car, make best use of public transport, not adversely affect highway safety for all users, encourage pedestrian movement; • be located and designed to promote a more integrated transport network; • encourage the efficient use of energy; • safeguard the efficient operation of the Island's ports for fishing, commercial and leisure use without compromising environmental objectives; and be well served by modern telecommunications without compromising the protection of the landscape. The overall objective for these may be summed up as being to protect pub lic-benefiting utilities and other assets and enable the orderly provision and co -ordination of these and other facilities for the benefit of the community. Since the Strategic Plan 2016 was adopted, some changes have occurred relevant to the services and utilities - changes to titles of service authorities and suppliers and changes to strategies and service types and terms used to describe those types. None of these changes alter the intention of the policies in the Strategic Plan and are thus taken into account in this Area Plan as natural evolutions of business operations. All-Island Strategies National Infrastructure Strategy15 While the Area Plan for the East is a short to medium term document, the National Infrastructure Strategy (NIS) aims to ensure there is an integrated, reliable, secure and resilient provision of Island-wide infrastructure that meets the social and economic needs of the Island up to 2050. The document presents an audit of the Island's current infrastructure, sets out the available capacities for each key asset and identifies any known issues with supply. It then examines a number of factors which could impact on the future provision of the Island's infrastructure: the Island's population and age structure, the spatial distr ibution of development, the economic situation of the Island, climate change, technological change and the need to meet national and international obligations and regulations. Finally, consideration is given to the obsolescence of each of the Island's key assets. Key assets in the East identified in the document are: • Douglas and Laxey harbours • Combined Cycle Gas Turbine (CCGT) facility at Pulrose and the Energy-from-Waste Facility at Richmond Hill • Gas pipeline for Glen Mooar to Pulrose Power Station • LPG stores in Douglas • The Douglas Water Treatment Works • West Baldwin, Clypse and Kerrowdhoo Reservoirs • Meary Veg sludge treatment facility The NIS Strategy identifies the following issues faced by specific assets: • Flood risk to the National Sports Centre, D ouglas Fire Station, Banks Circus bus depot, Douglas Railway Station, Pulrose Power Station and Pulrose Bridge after major flooding occurred in 2015; and • traffic congestion at Quarterbridge and Governor's Hill roundabouts. The Strategy concludes that the Island's key assets are currently ma
