Below you can find the individual policies from the Regulation 15 version of the Plan, as submitted to Breckland Council on 11 October 2020.
These will enable anyone wanting to focus on particular topics rather than read the whole Plan, to do that, particularly during the Regulation 16 Consultation to be organised by Breckland Council
These are the most important part of the the Plan as they tell developers, Breckland planners, and anyone else wanting to build in Saham Toney the rules they must adhere to.
You can find the supporting text for each policy in the full version of the Plan HERE
At the foot of the page you will find all of the Policy maps. The numbers of each file represent the policy numbers each map relates to
If any discrepancies are found between the extracts given here and the Neighbourhood Plan itself, the latter remains the master document
Please note: In these extracts bullet points are numbered; in the Plan itself they are lettered - this is just a quirk of the features of "Weebly" which we use to make this website.

The Plan aims to balance the 'privilege' it grants developers to build housing in Saham, with an obligation on them to help preserve and enhance the local environment. Thus there are two main policy groups, as listed below
GROWTH & DEVELOPMENT POLICIES
|
ENVIRONMENTAL PROTECTION POLICIES
|
POLICY 1: SERVICES, FACILITIES & INFRASTRUCTURE
P1.1 Where applicable, development proposals shall demonstrate the availability of adequate social infrastructure capacity and utilities capacity, to support and meet all the necessary requirements arising from the proposal. P1.2 In assessing this capacity, consideration must be given to how accessible social infrastructure is with a preference given to sustainable modes of transport (i.e. walking, cycling and public transport) over non-sustainable driving routes. P1.3 Development proposals that add to and enhance electric vehicle infrastructure will be supported in principle. P1.4 Necessary infrastructure will be required to be in place to support the timing of new development by adequately servicing the needs arising from such development. POLICY 2A: RESIDENTIAL HOUSING ALLOCATION
P2A.1 This Plan provides for 70 new homes up to 2036 through the allocation of sites, with an indicative delivery as follows (number of dwellings per site shown in brackets):
P2A.2 Nine sites are allocated in this Plan (through Policies 2H to 2P) for residential development; located as shown on Policy Map 2A. POLICY 2B: RESIDENTIAL DEVELOPMENT WITHIN THE SETTLEMENT BOUNDARY
P2B.1 New residential development within the settlement boundary, sensitively designed and of a scale consistent with the Neighbourhood Area's place within the Breckland settlement hierarchy will in principle be supported where:
POLICY 2C: RESIDENTIAL DEVELOPMENT OUTSIDE THE SETTLEMENT BOUNDARY
P2C.1 Outside, but including immediately adjacent* to the settlement boundary (as defined in the Local Plan), in addition to the allocated sites listed in Policy 2A, new residential development will be restricted to:
P2C.3 Should exceptional circumstances apply as set out in P2C.2, proposals for the development of brownfield sites on land outside but immediately adjoining the settlement boundary will be looked on favourably in preference to otherwise equivalent greenfield sites, where development will improve the visual appearance of the site and where the proposal includes measures to remove any form of public nuisance arising or which previously arose from the pre-existing use of the site. *The way in which the term ‘immediately adjacent’ is to be interpreted is defined in the glossary. policy 2D: AFFORDABLE HOUSING
P2D.1 Where a need for affordable housing is triggered by Local Plan Policy HOU 07, a local connection criterion will be applied for Site Allocations STNP4, STNP7 and STNP16, as well as on any other non-allocated sites coming forward that comprise 10 or more dwellings or have a site area equal to or greater than 0.5 hectares. This means the affordable housing will be of an appropriate mix and type to meet the identified local need and made available, in perpetuity, by preference to people on Breckland Council’s Housing Register with a local connection to the parish of Saham Toney, using the following hierarchy of priority:
P2D.3 Where a site is, or has been, in a single ownership, artificial sub-division to avoid provision of affordable housing will not be permitted. POLICY 2E: HOUSING MIX
P2E.1 All residential development proposals shall include a housing mix and tenure which respond to local housing need* having particular regard to the demographic characteristics of the Parish of Saham Toney. P2E.2 Sites that will deliver fewer than 10 dwellings are expected to deliver smaller homes of 3 bedrooms or less, in line with local housing needs*. P2E.3 For sites that will deliver 10 or more dwellings, the dwellings shall be of a size commensurate with local housing needs*, providing a mix and choice of houses, including 1- and 2-bedroom houses and the majority having 3 or less bedrooms. P2E.4 The following overall needs have been identified and all development proposals shall demonstrate how they have been satisfactorily addressed, in a proportionate manner:

P7A.2 In general development proposals will be supported where:
P7A.5 All proposals for sites located in settlement fringe areas of high or moderate-high combined landscape sensitivity, as set out in Table P7A.1, shall include a professionally prepared and proportionate Landscape and Visual Appraisal that provides full justification for the proposal in landscape and visual sensitivity terms, shows how the area's special landscape qualities will be preserved, and where possible enhanced, and sets out measures that will be taken to mitigate landscape impact. In such areas changes that would degrade the area's combined landscape sensitivity will not be supported. P7A.6 Where appropriate development does come forward outside the settlement boundary, opportunities will be sought to address the opportunity and management aims (as set out in the Saham Toney Parish Landscape Character Assessment 2019), for the rural / fringe character area in which a proposed site is located. Table P7A.1: Settlement fringe landscape sensitivities by area: policy 7b: key views
P7B.1 Development proposals shall seek opportunities to preserve, incorporate and where possible enhance the Key Views listed below and shown on Policy Map 7B, and their landscape setting. Development proposals which unacceptably impact on these key views will not be supported.
policy 7c: local green spaces
P7C.1 The open spaces listed below and shown on Policy Maps 7C.1 and 7C.2 are designated as Local Green Spaces.

P8G.1 For any development proposal where there is a residual risk of flooding (i.e. if the drainage system capacity will be exceeded in an event greater than the 1% AEP (Annual Exceedance Probability) plus climate change allowance, the proposals will be expected to demonstrate how the risk to people and property will be minimised. P8G.2 Where applicable, all proposals shall demonstrate that safe access and egress through a site will be maintained during a flood event that exceeds the 1% AEP plus 40% climate change. P8G.3 It shall be demonstrated that the drainage system is designed so that unless specifically designated to hold or convey water, flooding will not occur in any part of a building nor to utility plant that is susceptible to water. P8G.4 Where applicable, proposals shall identify safe exceedance routes and storage areas for residual flood water. P8G.5 All proposals shall demonstrate the use of appropriately flood resistant / resilient construction. policy 8h: design of sustainable drainage systems

P8H.8 SuDS features shall be provided with appropriate inlets, outlets and control components to manage the flow of water. Such components shall be resistant to blockage. P8H.9 Proposals shall demonstrate a minimum of 1.0m between the base of any soakaway and seasonally high groundwater levels. P8H.10 Wherever possible and practical, drainage system design proposals shall take every opportunity to improve (i.e. lessen) existing flood risk on a site and/or in downstream areas. P8H.11 Where applicable, design of SuDS systems shall include measures to improve land drainage via watercourses or ditches that form part of a site or run adjacent to its boundary, and make adequate provision for their future maintenance. P8H.12 Culverting of existing watercourses shall be avoided wherever possible. If adopted, it shall be in accordance with the Lead Local Flood Authority’s Standing Advice 1: Ordinary Watercourse Consenting. P8H.13 Design of temporary drainage for the construction phase shall be included where necessary and shall demonstrate construction activities will not lead to an increase in flood risk. P8H.14 SuDS design shall meet the most up to adoption standards of the Highways Authority and/or Anglian Water as applicable. policy 9: sewerage provision
P9.1 All new development will be expected to connect to the public foul sewerage network in accordance with the requirements of Anglian Water unless evidence is produced that it is not feasible to do so. P9.2 Evidence shall be provided by applicants to demonstrate that capacity* is available within the foul sewerage network, including at the treatment works and at intermediate pumping stations, or can be made available in time to serve the development. P9.3 If mains sewerage is demonstrably not feasible then an effective and sustainable private sewerage system plan shall be agreed with the Local Planning Authority in advance of development commencing. Such a plan must be implemented prior to the occupation of the first dwelling. P9.4 All development proposals for 10 or more houses shall include a sewerage capacity assessment. Where such assessment identifies a need for mitigation within the foul sewer network any foul drainage solution must be implemented before occupation commences. P9.5 All development proposals shall demonstrate that there is no increased risk of flooding either on the development site itself or to the wider area from sewers or artificial sources as a result of the development. P9.6 Foul sewers shall comply with the guidelines given in Water UK’s "Design and Construction Guidance", March 2020, or any more up to date version made available. *When calculating available capacity, 25% surface water infiltration, by volume, into the foul sewer shall be assumed, unless a lower figure is provided in written confirmation by Anglian Water in response to a pre-development enquiry. POLICY 3F: CLIMATE CHANGE ADAPTATION & MITIGATION
P3F.1 All new developments will be expected to embed the principles of climate change adaptation and mitigation into their proposal. To be supported, development proposals should provide this information in a Design and Access or Planning Statement. The level of information provided should be proportionate to the scale and nature of the proposed development. P3F.2 Development proposals which adopt innovative approaches to the construction of low carbon homes which demonstrate sustainable use of resources and high energy efficiency levels (for example construction to the passive house standard, or achieving net zero carbon emissions) will be particularly welcomed. P3F.3 Development that gives rise to zero emissions to air will be strongly encouraged. P3F.4 Measures to reduce carbon emitted during the manufacture of a building’s materials and its construction will be supported. P3F.5 Retrofit measures to reduce an existing building’s carbon emissions are encouraged and will be supported providing impact on external appearance is acceptable. |
