Flawed / Absent Local Plan site selection process to-date: Pickfield Nursery was submitted to EFDC in response to the Call for Sites consultation in 2008 and has subsequently been promoted through the current Local Plan process since its inception in 2012. EFDC’s July 2012 SLAA referred to Pickfield Nursery as site SR-0161 but incorrectly identified it as a duplicate site with a much larger parcel (SLAA Reference SR-0020). Representations were then submitted in October 2012 highlighting this mistake. However, despite the submission of detailed representations and subsequent regular liaison with EFDC’s officers (including a positive formal pre-application meeting), EFDC’s Site Selection evidence base published in 2016 discounted Pickfield Nursery prior to Stage 1 of the selection process, once again incorrectly considering it as a duplicate site. Pickfield Nursery was finally acknowledged as an individual site in the Local Plan evidence base in the “Sites for consideration following Regulation 18 consultation” list published in July 2017. However, at the time of writing these representations (26th January 2018, one working day before the Pre-Submission consultation deadline) an assessment of these sites has still not been undertaken and Appendix C1 of the Report on Site Selection (December 2017) has not been completed. -

The model simulates nitrogen and phosphorus processes in soils, groundwaters and river systems and can be applied in a semi-distributed manner at a range of scales. In this study, the model has been applied at field to sub-catchment to whole catchment scale to evaluate the behaviour of biosolid-derived losses of P in agricultural systems. It is shown that process-based models such as INCA, applied at a wide range of scales, reproduce field and catchment behaviour satisfactorily. The INCA model can also be used to generate generic information for risk assessment. By adjusting three key variables: biosolid application rates, the hydrological connectivity of the catchment and the initial P-status of the soils within the model, a matrix of P loss rates can be generated to evaluate the behaviour of the model and, hence, of the catchment system. -

15 Road Drainage and the Water Environment
HIGHWAYS AGENCY – M4 JUNCTIONS 3 TO 12 SMART MOTORWAY 15 ROAD DRAINAGE AND THE WATER ENVIRONMENT 15.1 Introduction 15.1.1 This chapter assesses the impacts of the Scheme on road drainage and the water environment during construction and operation, focussing on the effects of highway drainage on the quality and hydrology of receiving waters. In view of the long design-life of the Scheme (30 years for new gantries, 40 years for new carriageway construction, and 120 years for new bridges), the decommissioning phase of the Scheme has not been considered in this chapter because its effects are not predicted to be worse than the effects assessed during the construction and operational phases. The chapter assesses four principal impacts: a) effects of routine runoff on surface water bodies; b) effects of routine runoff on groundwater; c) pollution impacts from spillages; and d) flood impacts. 15.1.2 Although Interim Advice Note (”IAN”) 161/13 ‘Managed Motorways, All lane running’ (Ref 15-1) has scoped out the assessment of ‘Road Drainage and the Water Environment’ for smart motorway schemes, the assessment is required to ensure the protection of the water environment, to prevent its degradation, and ensure adequate mitigation measures are in place to prevent any adverse impacts. 15.1.3 The road drainage and water environment assessment for the Scheme has been undertaken in accordance with standard industry practice and statutory guidance. 15.1.4 This chapter details the methodology followed for the assessment, and summarises the regulatory and policy framework relating to road drainage and the water environment. -
Northern Thames Basin Area Profile: Supporting Documents
National Character 111: Northern Thames Basin Area profile: Supporting documents www.naturalengland.org.uk 1 National Character 111: Northern Thames Basin Area profile: Supporting documents Introduction National Character Areas map As part of Natural England’s responsibilities as set out in the Natural Environment White Paper1, Biodiversity 20202 and the European Landscape Convention3, we are revising profiles for England’s 159 National Character Areas (NCAs). These are areas that share similar landscape characteristics, and which follow natural lines in the landscape rather than administrative boundaries, making them a good decision-making framework for the natural environment. NCA profiles are guidance documents which can help communities to inform their decision-making about the places that they live in and care for. The information they contain will support the planning of conservation initiatives at a landscape scale, inform the delivery of Nature Improvement Areas and encourage broader partnership working through Local Nature Partnerships. The profiles will also help to inform choices about how land is managed and can change. Each profile includes a description of the natural and cultural features that shape our landscapes, how the landscape has changed over time, the current key drivers for ongoing change, and a broad analysis of each area’s characteristics and ecosystem services. Statements of Environmental Opportunity (SEOs) are suggested, which draw on this integrated information. The SEOs offer guidance on the critical issues, which could help to achieve sustainable growth and a more secure environmental future. 1 The Natural Choice: Securing the Value of Nature, Defra NCA profiles are working documents which draw on current evidence and (2011; URL: www.official-documents.gov.uk/document/cm80/8082/8082.pdf) 2 knowledge. -

Lee Valley Regional Park Landscape Character Assessment
LCT C: Urban Valley Floor with Marshlands SPA, which provides a nationally important habitat for overwintering birds. Cultural Influences 4.64 The low-lying land of rich alluvial deposits supported a system of grazing, referred to as the Lammas system5 from the Anglo-Saxon period to the end of the C19th. Grazing rights on the marshes were extinguished by the early C20th and a substantial proportion of the marshlands, with the exception of Walthamstow Marshes, were then modified by industrial activities and landfill, including the dumping of bomb rubble after WW2. In the 1950 and 60s the construction of flood relief channels ended the periodic inundation of the marshlands. 4.65 Communication routes through the valley floor proliferated over the C20th, including pylons, roads and railway lines mounted on embankments, but residential and industrial development remains largely confined to the margins. 4.66 Public access and recreation now characterises much of the marshlands, with some areas managed as nature reserves. However substantial infrastructure, such as the railway lines and flood relief channels and adjacent industrial development, means access through and into the marshes from surrounding urban areas is often severed. The tow-path following the River Lee Navigation provides a continuous link along the valley for visitors to enjoy the landscape. 5 A system of grazing whereby cattle was grazed only after the cutting and collection of hay Lee Valley Regional Park Landscape Strategy 85 April 2019 LCA C1: Rammey Marsh Lee Valley Regional Park Landscape Strategy 86 April 2019 LCA C1: Rammey Marsh Occasional long views out to wooded valley sides between Residential properties overlooking the southern area across the riverside vegetation.
