  • Joint Core Strategy for Broadland, Norwich and South Norfolk – Habitats Regulations Assessment Supplementary Note in Relation
    Joint Core Strategy for Broadland, Norwich and South Norfolk – Habitats Regulations Assessment Supplementary Note in relation to the parts of the Joint Core Strategy for Broadland, Norwich and South Norfolk to be re-published under Regulation 19 of the Town and Country Planning (Local Planning) (England) Regulations, 2012 Introduction The Joint Core Strategy for Broadland, Norwich and South Norfolk (JCS) was adopted in March, 2011. However, as a result of a legal challenge following the adoption of the JCS, parts of the strategy were remitted by Order of the High Court. This means that the relevant parts of the JCS (which are specified in a schedule to the Order) are treated as if they have been published as a preliminary to submission to the Secretary of State for examination by an independent inspector, but not progressed beyond that stage. The Order specified certain steps to be taken to enable the re adoption of the JCS, including publication as a preliminary to submission for independent examination. One of the requirements of publication is a Habitats Regulations Assessment. This is because, in accordance with article 6 (3) of the Council Directive 92/43/EEC (as amended) on the Conservation of Natural Habitats and of Wild Fauna and Flora (EC Habitats Directive), as transposed into UK law under the Conservation of Habitats and Species Regulations 2010, a task 1 Appropriate Assessment Test of Likely Significance indicated potential effects on European designated sites within the zone of influence of the policies included in the JCS. Subsequently a task 2 Appropriate Assessment of the JCS was produced in August, 2009, and a further updated Assessment produced in February, 2010.

  • Biodiversity Action Plan
    BIODIVERSITY ACTION PLAN April 2018 BROADS IDB – BIODIVERSITY ACTION PLAN Front cover images (L-R) Marsh Harrier ©Artur Rydzewski; Norfolk Hawker © Milo Bostock; Water Soldier; Water Vole; Berney Marshes ©Mike Page; BIDB Digger BROADS IDB – BIODIVERSITY ACTION PLAN FOREWORD This Biodiversity Action Plan (Second Edition) has been prepared by the Broads Internal Drainage Board in accordance with the commitment in the Implementation Plan of the DEFRA Internal Drainage Board Review for IDB’s, to produce their own Biodiversity Action Plans by April 2010. As such, the original version was published in January 2010. This revised version aims to continue to align the Broads IDB with biodiversity policy and more specifically, the Biodiversity document for England, “Biodiversity 2020: A strategy for Englands’ Wildlife and Ecosystem Services” and build on the Government’s 25 Year Environmental Plan; A Green Future. In doing so, the document strives to demonstrate the Board’s commitment to fulfilling its duty as a public body under the Natural Environment and Rural Communities Act 2006 to conserve biodiversity. Many of the Board’s activities have benefits and opportunities for biodiversity, not least its water level management and watercourse maintenance work. It is hoped that this Biodiversity Action Plan will help the Board to maximise the biodiversity benefits from its activities and demonstrate its contribution to the targets as part of the Biodiversity 2020 strategy and achieve wider environmental improvement within its catchments. The Board has adopted the Biodiversity Action Plan as one of its policies and subject to available resources is committed to its implementation. It will review the plan periodically and update it as appropriate.

  • Emergency Response Plan 2006
    Emergency Response Plan 2006 Protection marking: Version: 1 Date: April 2006 Foreword The Breckland Council Emergency Response Plan replaces all previous editions, which should now be destroyed. Under the provisions of the Civil Contingencies Act 2004, the requirement to have in place adequate Emergency Planning and Business Continuity strategies is significantly enhanced. It is important that we all recognise the statutory requirements which have to be in place, adequate emergency response arrangements etc is placed upon the entire Breckland Council staff and not just one department or team. We must have staff adequately trained and prepared to undertake their ‘emergency roles’ and the District Emergency Planning Officer will continue her work to ensure that Breckland Council is ready to meet its commitments under a single or multi agency response to any major or significant emergency which could occur with the County. The Emergency Response Plan will be distributed to appropriate personnel throughout the Authority. Many of the arrangements outlined in the various sections of this plan are generic and the principles will be applied to our response to any major or significant emergency situation, whether it is purely one which affects the internal operations of Breckland Council or the wider community of Norfolk. This document should be read in conjunction with the Breckland Council Business Continuity Plans. All staff should take every opportunity to understand the role of Breckland Council when dealing with major or significant emergencies.

    NORFOLK BIODIVERSITY ACTION PLAN Ref 1/S12 Tranche 1 Species Action Plan 12 WHITE-CLAWED CRAYFISH Plan Author: Environment Agency (Austropotamobius pallipes) Plan Co-ordinator: Environment Agency This is a lobster-like crustacean that grows to Plan Leader: Waterbodies Group about 12cm (5 inches) long. They mainly live in Date: Stage: clean flowing water and are mostly active by 31 December 1998 Final Draft night. February 2002 Final Revised Draft 1. CURRENT STATUS National Status • White-clawed crayfish is the only native species of freshwater crayfish in the UK. It is widespread in clean, calcareous streams, rivers and lakes in England and Wales and occurs in a few areas in Northern Ireland, but many populations have been lost since the 1970s. The species is listed in Appendix III of the Bern Convention and Annexes II and V of the EC Habitats Directive. It is classed as globally threatened by IUCN/WCMC. It is also protected under Schedule 5 of the Wildlife and Countryside Act in respect to taking from the wild and sale, and is proposed for addition to Schedule 5 of the Wildlife (Northern Ireland) Order 1985. Norfolk Status • White-clawed crayfish are found in the Rivers Wensum, Tat, Bure, Glaven and Yare. 2. CURRENT FACTORS CAUSING LOSS OR DECLINE IN NORFOLK • The habitat required by this species is very vulnerable to modifications through the management of rivers and changes in water quality. • White-clawed crayfish are out-competed by non-native crayfish (eg signal crayfish Pacifastacus leniusculus) In Norfolk, signal crayfish are known to be present in the River Wensum, Reepham Tributary and River Yare.

  • Proposed Mineral Extraction Sites
    Proposed Mineral Extraction Sites 104 Breckland Sites Map of proposed sites in Beetley (MIN 08, MIN 12, MIN 13, MIN 51) MIN 12 - land north of Chapel Lane, Beetley Site Characteristics • The 16.38 hectare site is within the parish of Beetley • The estimated sand and gravel resource at the site is 1,175,000 tonnes • The proposer of the site has given a potential start date of 2025 and estimated the extraction rate to be 80,000 tonnes per annum. Based on this information the full mineral resource at the site could be extracted within 15 years, therefore approximately 960,000 tonnes could be extracted within the plan period. • The site is proposed by Middleton Aggregates Ltd as an extension to an existing site. • The site is currently in agricultural use and the Agricultural Land Classification scheme classifies the land as being Grade 3. • The site is 3.7km from Dereham and 12km from Fakenham, which are the nearest towns. • A reduced extraction area has been proposed of 14.9 hectares, which creates standoff areas to the south west of the site nearest to the buildings on Chapel Lane, and to the north west of the site nearest the dwellings on Church Lane. Amenity: The nearest residential property is 11m from the site boundary. There are 21 sensitive receptors within 250m of the site boundary. The settlement of Beetley is 260m away and Old Beetley is 380m away. However, land at the north-west and south-west corners is not proposed to be extracted. Therefore the nearest residential property is 96m from the extraction area and there are 18 sensitive receptors within 250m of the proposed extraction area.
