This assessment helps the plan-makers to identify the relative environmental performance of proposed Objectives, Policies and Actions, and to evaluate which of these may be more sustainable. 0.1.3 SEA is a statutory process incorporating the requirements of the European Union Strategic Environmental Assessment Directive. 0.2 About the Luton Local Flood Risk Management Strategy 0.2.1 Luton Borough Council is a Lead Local Flood Authority and therefore has a duty to produce, maintain, implement and monitor a Local Flood Risk Management Strategy for its area. The Luton LFRMS will: Ensure a clear understanding of the risks of flooding locally, so that investment in risk management can be prioritised more effectively; Set out clear and consistent plans for risk management so that communities and businesses can make informed decisions about the management of the remaining risk; Manage flood risks in an appropriate way, taking account of the needs of communities and the environment; Ensure that emergency plans and responses to flood incidents are effective and that communities are able to respond effectively to flood forecasts, warnings and advice; and Help communities to recover more quickly and effectively after incidents. 0.3 Purpose and Content of the Environmental Report 0.3.1 The purpose of this Environmental Report is to: Identify, describe and evaluate the likely significant effects of the LFRMS and its reasonable alternatives; and Provide an early and effective opportunity for statutory consultees, interested parties and the public to offer views on any aspect of the SEA process which has been carried out to date. i SEA for the Luton Local Flood Risk Management Strategy: Environmental Report August 2015 Executive Summary UE-0161 SEA- Luton LFRMS ER_3_150805 0.3.2 The Environmental Report contains: An outline of the contents and main objectives of the LFRMS and its relationship with other plans, programmes and strategies; Relevant aspects of the current state of the environment and key sustainability issues for the borough; The SEA Framework of objectives and decision-making criteria against which the LFRMS has been assessed; The appraisal of alternative options for the LFRMS; The likely significant environmental effects of the LFRMS; The measures envisaged to prevent, reduce and as fully as possible offset any significant adverse effects which may arise as a result of the LFRMS; A description of the measures envisaged concerning monitoring; and The next steps for the SEA. 0.4 The SEA Scoping Stage 0.4.1 The Scoping Report was published for consultation between 26 November 2014 and 14 January 2015. It set out the intended scope and level of detail to be included in the SEA and included a plan, programme and strategy review, an evidence base for the assessment, key issues and environmental challenges to address, and an SEA Framework of objectives against which the LFRMS can be assessed. 0.4.2 The SEA Framework is comprised of six SEA Objectives, listed below, which were developed for use in the appraisal. # SEA Objective Relationship to SEA Directive 1 To conserve and enhance biodiversity Biodiversity, flora and fauna 2 To promote adaptation to climate change Climatic factors; Material assets; Population; Human health 3 To conserve and enhance the historic environment, heritage Landscape; Historic assets and their settings environment 4 To conserve and enhance the character of the landscape Landscape; Historic environment 5 To protect water resources and minimise water pollution Water 6 To conserve and manage natural resources (land, minerals, Material assets; Soil agricultural land, materials) ii SEA for the Luton Local Flood Risk Management Strategy: Environmental Report August 2015 Executive Summary UE-0161 SEA- Luton LFRMS ER_3_150805 0.4.3 Following consultation the information presented in the Scoping Report was updated to take account of the responses received. The revised scoping information is included in this Environmental Report. 0.5 Assessment of Reasonable Alternatives 0.5.1 The purpose and content of the LFRMS is clearly defined by law which means that there is limited scope for the consideration of markedly different alternatives. However, at points during the development of the LFRMS certain decisions were made for which alternatives were available. 0.5.2 Following the conclusion of the scoping stage, the SEA team contributed to the development of options work carried out for the LFRMS via the High Level Assessment. The purpose of this interaction between the SEA and the LFRMS was to inform and influence the strategy’s development and to provide an early and effective environmental input, and included suggestions for additional reasonable alternatives which could be considered alongside the Policies and Actions proposed for inclusion in the LFRMS. These can be summarised as: Policy 1: Thresholds for flood investigations; Alternative 1a: Set lower thresholds for initiating formal flood investigations (e.g. 5 or more adjacent dwellings and/or 1 or more business premises); CDA 1a: High priority Critical Drainage Areas (CDA) are high risk and have synergy with other projects; medium priority are those with <£25,000 cost per property mitigated; all others are low; CDA 1b: Alternative - Different approach to prioritisation of CDAs (e.g. medium priority are those with <£30,000 cost per property mitigated; all others are low); Policy 2: Sand bags; Alternative 2a: Supply sand bags to selected groups of residents in chosen locations; Action 6.1: Water efficiency (retrofitting); and Action 6.1a: Alternative - Water Efficiency (retrofitting) - higher target e.g. 60% of existing housing stock. 0.5.3 Overall the High Level Assessment found the Luton LFRMS to be a broadly sustainable strategy with a wide range of positive effects and few negative environmental effects. However, a number of Flood Alleviation Scheme (FAS) proposals for certain Critical Drainage Areas were flagged as leading to uncertain or mixed environmental effects the nature of which would largely depend on their means of implementation.
