National Planning Policy Framework (NPPF) • Identify the size, type, tenure and range of housing that is required in particular 2.1 At the heart of the NPPF is a presumption in locations, reflecting local demand; and favour of sustainable development. For plan- making this means that local planning authorities • Where they have identified that affordable should positively seek opportunities to meet the housing is needed, set policies for meeting development needs of their area. Local Plans this need on site, unless off-site provision or should meet objectively assessed needs, with a financial contribution of broadly equivalent sufficient flexibility to adapt to rapid change, unless value can be robustly justified (for example any adverse impacts of doing so would significantly to improve or make more effective use of and demonstrably outweigh the benefits, when the existing housing stock) and the agreed assessed against the policies in the NPPF taken as approach contributes to the objective of a whole; or specific policies in the NPPF indicate creating mixed and balanced communities. development should be restricted. Such policies should be sufficiently flexible to take account of changing market 2.2 NPPF paragraph 47 states that in order to conditions over time. boost significantly the supply of housing Local Planning Authorities should use their evidence base to ensure that their Local Plan meets the full objectively assessed needs for market and affordable housing in the housing market area, as far as is consistent with the policies set out in this Framework, including identifying key sites which are critical to the delivery of the housing strategy over the plan period.
2.3 NPPF paragraph 50 states that to deliver a wide choice of high quality homes, widen opportunities for home ownership and create sustainable, inclusive and mixed communities, local planning authorities should:
• Plan for a mix of housing based on current and future demographic trends, market trends and the needs of different groups in the community (such as, but not limited to, families with children, older people, people with disabilities, service families and people wishing to build their own homes);
Figure 2.1> National Planning Policy Framework 7
2.4 Paragraph 55 states that to promote sustainable 2.5 Local Plans are the key to delivering sustainable development in rural areas, housing should be development that reflects the vision and aspirations located where it will enhance or maintain the vitality of local communities. Local Plans must be of rural communities. For example, where there are prepared with the objective of contributing to the groups of smaller settlements, development in one achievement of sustainable development. Local village may support services in a village nearby. planning authorities should seek opportunities to achieve each of the economic, social and environmental dimensions of sustainable development, and net gains across three. Local Plans should be aspirational but realistic. They should address the spatial implications of economic, social and environmental change.

Figure 3.1> Facilities Plan 12 4.0 Site Assessment To ensure the delivery of this Site, which sensitively and positively integrates with the existing urban area, a range of technical assessments of the Site have been undertaken on behalf of Taylor Wimpey. This assessment work is described below, with key physical features and development opportunities and constraints identified for the Site. This work has shaped and informed the design response to the Site which is presented as a framework masterplan in Section 5.
Topography 4.5 Opportunities to provide a pedestrian and cycle connection from Eggington Road through the Site 4.1 The Site is gently sloping with gradual falls and connecting with the existing pedestrian route towards the Etwall Brook and north towards from Old Station Close and the SUSTRANS Route dwellings on The Bancroft.

Sustainable Transport
4.9 Two regular bus services operate within Etwall close to the Site. Service numbers V1 and V2 operate along Eggington Road and Hilton Road to the north of the Site and provide an hourly weekday link between Burton and Derby. The nearest bus stops to the Site are located to the east of the Site on Eggington Road opposite The Bancroft and can be accessed from the Site via existing footways along Eggington Road. This stop is currently served by the V1 service and is unmarked.
4.10 Willington Rail Station is the nearest station to the Site and is situated approximately 5km to the south-east of the Site. Willington Station can be accessed via bus services V1 and V2 and provides services to a number of significant locations including Derby, Nottingham and Birmingham.

The following sections explain the main components and strategies underpinning the framework, namely those focused on the distribution of land uses; access and movement; landscape, ecology and drainage; and the indicative phasing and delivery of development.
Land Use and Amount 5.3 Up to 30% of the dwellings (36 dwellings in total) can be offered as affordable dwellings. Of 5.1 Table 5.1 and Figure 5.1 provide an indication the overall 30% provision, the following mix is of the proposed distribution of land uses and how indicatively suggested: they are broken down. The predominant land use will be residential, with the site capable of delivering • 1 and 2 bedroom dwellings (68%) up to 120 dwellings on a net developable area of approximately 3.78 hectares on the 7.9 hectare site. • 3 bedroom dwellings (32%)
5.4 Within the Site, a total of 2.62 hectares is 5.2 An indicative mix of dwellings has been used to inform the illustrative layout plan which comprises identified as informal/natural green space or of the following and demonstrates just one option informal/natural public amenity space. This of how the site could be developed: equates to almost one third of the combined site area.

5.7 Access will be served directly from Egginton 5.9 In defining sustainable development, the NPPF Road to service the entire development. The new requires development proposals to be sustainable access has been designed to tie into the existing in terms of its economic, social and environmental function of Eggington Road as well as connect into roles. As such, Table 5.2 outlines how the the existing pedestrian footpath. The position has proposals accord with the definition of ‘sustainable been safety audited to confirm that it will function development’ as set out within paragraph 7 of the without impact to the existing junctions to the east NPPF. of the Site.
5.8 The existing southern access track for agricultural purposes will be retained as will the existing access route to the STW. It will not be possible for private care users to utilise these access points, which is consistent with the current operation of these access points.
The construction of the proposed development would support construction jobs directly related to the development. The provision of 120 dwellings will generate additional convenience, comparison and leisure services expenditure in the local area. An economic role/ economic benefits The Council will gain a direct contribution through the New Homes Bonus, provided by the Department for Communities and Local Government. The proposed development will generate additional Council Tax payments to the Council. The provision of 120 new homes will support the creation of strong, vibrant and healthy communities. The provision of 30% affordable housing will increase the District’s supply of affordable homes and help to reduce inequalities, amounting to 26 dwellings of the proposed 120 dwellings to be delivered as affordable housing. The development of the Site for residential uses would contribute towards a shortfall in the five-year supply of deliverable housing land, in a sustainable location. A social role/social benefits The proposed development incorporates formal and informal open spaces which are within easy walking distances of the new homes and will encourage the development of healthy communities as well as ensuring positive linkages with the existing community in Etwall. The Site is in an accessible location with connections to pedestrian routes (including the SUSTRANS Route 549), which link to the key services and facilities located within Etwall.
The proposed development includes retention of key existing ecological assets and the enhancement of biodiversity including the areas of planting and trees across the Site and the provision of new green infrastructure in accordance with the landscape strategy. The Site adjoins the existing built-up boundary of Etwall, which has been identified as a Key Service Village as part of the Local Plan (Part 1). As such a number of shops An environmental role/ environmental and services are located either within walking distance or via existing bus routes thus benefits reducing the need for the private car. The Site is well contained by existing built-form or permanent boundaries ensuring that the impact on the surrounding landscape is minimised. Provision of Sustainable Urban Drainage Systems (SUDS) including onsite attenuation ponds and no adverse impact on flood risk. A commitment to sustainable waste management and construction during development and occupation. Table 5.2> Sustainable Development Principles Table 23 24 6.0 Landscape, Ecology & Drainage A strong landscape framework will form an important part of the proposals. The development of the Site provides the opportunity to enrich and strengthen the existing landscape structure, whilst improving ecological and recreational functions.

7.3 The Site would provide areas of public open space for leisure and recreational purposes within its boundaries. This would be provided via two formal areas of open space completed by significant landscape buffers along key site boundaries. The landscape buffers and SUDS provision will also provide zones to enhance ecological biodiversity on the Site. 27 Kathryn Ventham Planning Partner Email: [email protected] Telephone: 0121 711 515
