general standards towards acceptable development visual and neighbouring amenity
General Policy 2: Development which is in accordance with the land-use zoning and proposals in the appropriate Area Plan and with other policies of this Strategic Plan will normally be permitted, provided that the development: (a) is in accordance with the design brief in the Area Plan where there is such a brief; (b) respects the site and surroundings in terms of the siting, layout, scale, form, design and landscaping of buildings and the spaces around them; (c) does not affect adversely the character of the surrounding landscape or townscape; (d) does not adversely affect the protected wildlife or locally important habitats on the site or adjacent land, including water courses; (e) does not affect adversely public views of the sea; (f) incorporates where possible existing topography and landscape features, particularly trees and sod banks; (g) does not affect adversely the amenity of local residents or the character of the locality; (h) provides satisfactory amenity standards in itself, including where appropriate safe and convenient access for all highway users, together with adequate parking, servicing and manoeuvring space; (i) does not have an unacceptable effect on road safety or traffic flows on the local highways; (j) can be provided with all necessary services; (k) does not prejudice the use or development of adjoining land in accordance with the appropriate Area Plan; (l) is not on contaminated land or subject to unreasonable risk of erosion or flooding; (m) takes account of community and personal safety and security in the design of buildings and the spaces around them; and (n) is designed having due regard to best practice in reducing energy consumption. 6.3 Development outside of areas zoned for development
Isle of Man Strategic Plan 2016
promote good design and use of local materials and character
Strategic Policy 3: Proposals for development must ensure that the individual character of our towns and villages is protected or enhanced by: (a) avoiding coalescence and maintaining adequate physical separation between settlements; and (b) having regard in the design of new development to th e use of local materials and character. 4.3.4 Most of our built heritage, our countryside, our coastline and our natural environment is of attraction, value and interest. Surveys commissioned by Government on the quality of life and the importance of heritage in the Isle of Man and internationally, have consistently shown that the historic landscape setting of the Isle of Man scores as t he single most significant factor for residents and visitors in supporting the concept of a specific and positive Manx identity. This "heritage identity" is a result of the combination of a rich diversity of historic sites and monuments, historic building s and residential settlements and a specific range of natural history attributes set within a predominantly rural landscape setting which links modern life to a sense of historic legacy and beauty, the retention of which is strongly supported by Government and the resident community. 4.3.5 The landscapes of the Island are very varied, and their nature and variety is the consequence of thousands of years of interaction between the natural and cultural aspects of the Island through human activity within the enviro nment and an innate respect for the natural and historic qualities they represent. 4.3.6 This landscape heritage is more than simply the sum of its parts. The combination of geology, geomorphology, wildlife, archaeology, history, traditional buildings and the natural settings for traditional activities and customs, combine in the rural and built environment to provide an inseparable element of "Manxness". It provides an overarching context which makes the landscapes of the Isle of Man unique and gives them the value which is acknowledged by those who live here and those who visit. The protection and promotion of this element within Manx society is an important element in central Government policy and the Strategic Plan, which both support the view that these v alued characteristics of the Isle of Man be acknowledged and protected for the future from inappropriate development. 4.3.7 This protection will apply to areas of heritage value, to sites of heritage value and to general traditional landscape settings within the Island which are deemed to contribute to the sense of the Island's heritage identity. Heritage landscape value will therefore be a consideration in all aspects of planning, with a view to retaining and enhancing this value wherever possible.

promote good design and use of local materials and character
Strategic Policy 5: New development, including individual buildings, should be designed so as to make a positive contribution to the environment of the Island. In appropriate cases the Department will require planning applications to be supported by a Design Statement which will be required to take account of the Strategic Aim and Policies. 4.4 Economy 4.4.1 The Spatial Strategy identifies the Major Employment Areas around the Island. While the majority of business and employment is focused around the Douglas Metropolitan Area, there are other major employment areas at Castletown, the Airport/Freeport, Peel, Ramsey and Jurby. The Department considers the distribution of employment areas provides a spread of employment opportunities around the Island. While recognising the opportunities for small scale local employment within existing centres it is considered new employment should, in the main, be concentrated within existing settlements or those major employment areas referred to in the Island Spatial Strategy and illustrated on the Key Diagram. Existing Local and new Area Plans will provide detailed boundar ies for these areas. From time to time Government may judge it appropriate to offer financial incentives to encourage economic activity or investment in particular parts of the Island.

any increased impact on neighbours
Environment Policy 23: When considering alterations and improvements to existing facilities the Department will require that consideration be given to the potential adverse impact of the proposed changes to existing neighbours. 7.18 Environmental Impact Assessment(1) 7.18.1 Environmental Impact Assessment (EIA) is an important procedure for ensuring that the likely effects of new development on the environment are fully understood and taken into account before the development is allowed to go ahead. It is a process by which information about the likely environmental effects of certain types of development is collected, assessed and taken into account by the developer (as part of project design) and by the planning authority (in determining the acceptability of the application). In cases w here developments are likely to have significant environmental effects, whether public or private, by virtue of their nature, size or location, EIA's will be required and the general principles set out in Appendix 5 should be followed. 7.18.2 For some types of development, EIA's will be required in every case, whilst other development will only require an EIA if the particular project is judged likely to give rise to significant environmental effects. Where development does not fall wit hin these categories, (1) Environmental Impact Assessment is defined in Appendix 1 but still has a significant effect on the environment, the Department will require suitable supporting environmental information. The main criteria for judging significance are as follows: i. major developments which are of more than local importance; ii. developments which are proposed in particularly environmentally sensitive or vulnerable locations; iii. developments with unusually complex and potentially hazardous environmental effects. 7.18.3 A Planning Policy Statement will be issue d specifying the manner in which the Department intends to deal with applications which should be subject to EIA. Pending the adoption of the proposed Planning Policy Statement the Department will adopt current practice on EIA's from England and Wales set out in the publication "Environmental Impact Assessment: A Guide to Procedures" (1).

pment. 8.13.2 The extent of formal open space with in settlement boundaries in the South is identified on the Proposals Map (Map 3) and Inset Maps (Maps 4-7). The Isle of Man Strategic Plan (Environment Policy 42) seeks to protect these open spaces and indicates that: 8.13.3 "Inappropriate backland development, and the removal of open or green spaces which contribute to the visual amenity and sense of place of a partic ular area will not be permitted.''
