Erection of a replacement dwelling

Housing Policy 14

Housing Policy 14: Where a replacement dwelling is permitted, it must not be substantially different to the existing in terms of siting and size, unless changes of siting or size would result in an overall environmental improvement; the new buildi ng should therefore generally be sited on the "footprint" of the existing, and should have a floor area (1), which is not more than 50% greater than that of the original building (floor areas should be measured externally and should not include attic space or outbuildings). Generally, the design of the new building should be in accordance with Policies 27 of the present Planning Circular 3/91, (which will be revised and issued as a Planning Policy Statement). Exceptionally, permission may be granted for bui ldings of innovative, modern design where this is of high quality and would not result in adverse visual impact; designs should incorporate the re -use of such stone and slate as are still in place on the site, and in general, new fabric should be finished to match the materials of the original building. Consideration may be given to proposals which result in a larger dwelling where this involves the replacement of an existing dwelling of poor form with one of more traditional character, or where, by its design or siting, there would be less visual impact. 8.11.3 It is unlikely that permission will be given for permanent replacement of dwellings which were never intended to have a permanent residential use, such as chalets and other structures built of materials for only temporary or seasonal use. 8.12 Extensions to Residential Property 8.12.1 Extensions to Dwellings in built up areas or sites designated for residential use As a general policy, in built up areas not controlled by Conservation Area or Registered Building policies, there will be a gener al presumption in favour of extensions to existing property where such extensions would not have an adverse impact on either adjacent property or the surrounding area in general. (3) Floor Space is defined in Appendix 1 (1) Floor Area is defined in Appendix 1 8.12.2 Extensions to properties in the countryside As there is a general p olicy against development in the Island's countryside, it is important that where development exists, either in an historic or recently approved form, it should not, when altered or extended detract from the amenities of the countryside. Care therefore, must be taken to control the size and form of extensions to property in the countryside. In the case of traditional properties, the proportion and form of the building is sensitively balanced and extensions of inappropriate size or proportions will not be ac ceptable where these destroy the existing character of the property. In the case of non -traditional properties, where these are of poor or unsympathetic appearance, extensions which would increase the impact of the property will generally not be acceptable . It may be preferable to consider the redevelopment of non -traditional dwellings or properties of poor form with buildings of a more traditional style and in these cases, the Department may consider an increase in size of the replacement property over and above the size of the building to be replaced, where improvements to the appearance of the property would justify this.

replacement of existing dwellings

Housing Policy 12: The replacement of an existing dwelling in the countryside will generally be permitted unless: (a) the existing building has lost its residential use by abandonment; or (b) the existing dwelling is of architectural or historic interest and is capable of renovation. In assessing whether a property has lost its habitable status (1) by abandonment, regard will be had to the following criteria: (i) the structural condition of the building; (ii) the period of non-residential use(2) or non-use in excess of ten years; (iii) evidence of intervening use; and (iv) evidence of intention, or otherwise, to abandon.

• Mount Murray Golf Club • Onchan Park • West Baldwin Reservoir Car Park • Clypse Kerrowdhoo Reservoir Car Park • Conrhenny Car Park • Ballanette Nature Reserve • Axnfell Plantation Natural Environment Proposal 7 Proposals for development in the vicinity of Dark Sky Discovery Sites are to have minimal outdoor lighting and be encouraged to have a design response which is non-intrusive into the darkness of night. Baffling and directionality of lighting must be sensitive to contain any necessary lighting within a subject site only. Watercourses and Wetlands The collection of hills in the East has produced a network of mountain streams which gradually join and widen to become the rivers flowing out into Douglas Bay, Port Groudle and Laxey Bay. Several of these rivers fro m the natural boundaries between the Eastern Parishes. A non-exhaustive list of streams and rivers in the East includes: Crammag River Injebreck River Creg-y-Cowin River West Baldwin River Awin Ny Darragh Baldwin River River Glass Greeba River River Dhoo Santon Burn Crogga River Middle River Laxey River Glenroy River Groudle River Ballacottier River River Douglas It is likely that these streams and rivers, similar to most of the Island's watercourses, support populations of European Eels - classified by the International Union for the Conservation of Nature (IUCN) as Critically Endangered - and Brown Trout. Most rivers with good fish passage from the sea, including the Dhoo, Glass, Laxey and Santon Burn, contain populations of salmon and sea trout. The Dhoo and Glass are known also to support populations of brook (and possibly river) lamprey. Many of the tributary streams to the major rivers, although small, provide valuable additional spawning and nursery areas for salmonids and lampreys. There are four reservoirs in the East: Eairy Dam, Injebreck, Clypse and Kerrowdhoo. The proposals in this plan for additional housing in the East are likely to have an impact on the water levels in these reservoirs and consequently on the compensation flows within the downstream rivers. DEFA reports that i n recent years there has been evidence of low summer flow below Injebreck reservoir in the River Glass. It is suggested that any reduction in flow in the River Glass could have consequences for the ecology of the river, including fish populations. DEFA has highlighted evidence that artificial light from new housing close to rivers may have a detrimental impact on migratory salmonids. The reservoirs in the East are home to wild brown trout and Injebreck, Clypse and Kerrowdhoo are stocked with rainbow trout for visiting anglers. This Plan recognises that the economic value of the recreational fishing industry depends both on healthy fish stocks and high recreation and visual amenity. The ecological services provided by the Island's watercourses and wetlands are considerable, including carbon storage and natural flood mitigation. An undeveloped corridor of land between the river bank (measured from the edge of th e river channel) and any riverside development is required to allow for natural changes in the position of the river channel, as well as in water levels . The natural vegetation and physical structure of a river bank also provides a wildlife corridor for non-aquatic species. Natural Environment Proposal 8 Proposals for new development in the Plan Area which intend a connection to the Injebreck Reservoir for its water supply must demonstrate that as a consequence of this new development, water levels will n ot be so affected as to have a detrimental effect on normal flows. Natural Environment Recommendation 2 It is recommended that ahead of making any applications for development close to the reservoirs, watercourses and wetlands in the East, applicants must discuss such proposals with DEFA to establish the need for specific design elements to be taken into account . This may include : the impact of artificial light from the development on migratory fish species, buffer distances from the river bank and visual amenity. Marine Protected Areas and Marine Conservation Zones Increased efforts are being made to protect the health and biodiversity of the marine environment as well as the economic and social benefits which effective management of marine resources brings. Marine protected areas are areas of the sea that are protected from fishing and other impacts, with the aim of restoring habitats and supporting sustainable fisheries. The Isle of Man currently has ten Marine Protected Areas around our coast, encompassing 10.4% of Manx waters. One of these is the Sea Fisheries Restricted Area at Laxey Bay which was established in 2009 with the intention of enh ancing the scallop stock and later seeded with juvenile scallops. In 2008 , Douglas Bay closed to mobile fishing gear. Its current status is as a Marine Conservation Zone, though there is an intention to designate the Bay as a Marine Nature Reserve. Marine Nature Reserves are designated to conserve their flora,
