This is constantly under road noise. discussion, with little success so far. Action 2: Improve safety The Parish Council now participate in the local transport group at slip-roads to with the police and neighbouring councils. The Chair of our A34 Parish Council has been very active in putting forward our concerns. Action 3: Reduce traffic New road markings on the Hill have not really solved the speed on Hinksey problem. Cats-eyes in the road have simply created a new Hill noise problem as large vehicles have to rumble over them. Action 4: Reduce the risk The Flood group has made progress with action taken by the of flooding railway authority to clear drain blockages and clearance of ditches and underground pipes in the village. In the last very heavy downpour there was no flooding in the village. Unfortunately the proposed bund around the village has been abandoned because the Environment Agency could not justify the high expenditure. Action 5: Improve and We have managed to get limited road repairs done in the repair roads, pavements village. Cutting back of overhanging hedges and removal of and footpaths litter particularly on Hinksey Hill has also been done. More pavement and road repairs are needed. Action 6: Improve parking Parking in the village has actually become more of a problem in the village since the pub car park has been fenced off. We are still working on this. Action 7: Upgrade bridge Network Rail have agreed to construct a "Wheelie ramp" on to New Hinksey to the Devil’s Backbone bridge improve cycle access Action 8: Create new We are working with Sustrans, the national cycle network, on cycling and walking establishing new cycle trails throughout the parish.

    OFFICIAL Rule 10(2)(d) Transport and Works Act 1992 The Transport and Works (Applications and Objections Procedure) (England and Wales) Rules 2006 Network Rail (Oxford Station Phase 2 Improvements (Land Only)) Order 202X Report summarising consultations undertaken 1 Introduction 1.1 Network Rail Infrastructure Limited ('Network Rail') is making an application to the Secretary of State for Transport for an order under the Transport and Works Act 1992. The proposed order is termed the Network Rail (Oxford Station Phase 2 Improvements (Land Only)) Order ('the Order'). 1.2 The purpose of the Order is to facilitate improved capacity and capability on the “Oxford Corridor” (Didcot North Junction to Aynho Junction) to meet the Strategic Business Plan objections for capacity enhancement and journey time improvements. As well as enhancements to rail infrastructure, improvements to highways are being undertaken as part of the works. Together, these form part of Oxford Station Phase 2 Improvements ('the Project'). 1.3 The Project forms part of a package of rail enhancement schemes which deliver significant economic and strategic benefits to the wider Oxford area and the country. The enhanced infrastructure in the Oxford area will provide benefits for both freight and passenger services, as well as enable further schemes in this strategically important rail corridor including the introduction of East West Rail services in 2024. 1.4 The works comprised in the Project can be summarised as follows: • Creation of a new ‘through platform’ with improved passenger facilities. • A new station entrance on the western side of the railway. • Replacement of Botley Road Bridge with improvements to the highway, cycle and footways.

  • Enough Is Enough! Stop Oxford Flooding(4)+Caveat
    Enough is Enough! Stop Oxford Flooding Caveat and disclaimer: this article is written in good faith as our best understanding at the time of writing, March 2014. However very little is decided for sure, and things can and will change, the scheme may never even happen, so nothing said here should be taken as gospel or relied on for taking important decisions. ---------------------------------------------------------------------------------------------------------------------- The Oxford Flood Alliance has been campaigning since 2007 to reduce Oxford’s flood risk. We have had real success but have always known that more would need to be done. Here are the reasons why we strongly support the proposed “Western Conveyance” What follows is based on our best understanding at present. There are several years of planning ahead before work on the ground begins. Something needs to be done to reduce Oxford’s flooding Oxford has suffered increasingly frequent flooding in recent years, a problem which is only likely to increase in future. There are serious effects on individuals, families, businesses, the universities, railways and roads, and the sewerage system. Oxford and Oxfordshire’s economy is damaged, along with its reputation as a place to work and to do business. Action needs to be taken to rid Oxford of this threat once and for all. We support the proposed Western Conveyance (also known as the Oxford Relief River, ORR). This is a scheme devised by the Environment Agency and the subject of public consultation in 2009. If various bodies can together in partnership raise the necessary £123 million, it is likely to be given the go ahead next month.

  • Samuel Lipscomb Seckham
    Samuel Lipscomb Seckham By PETER HOWELL l TIL recently the name of Samuel Lipscomb Seckham was fairly widely U known in Oxford as that of the architect of Park Town. A few other facts, such as that he was City Surveyor, were known to the cognoscenti. No-one, however, had been able to discover anything significant about his background, let alone what happened to him after he built the Oxford Corn Exchange in 1861-2. In '970 a fortunate chance led to the establishment of contact with Dr. Ann Silver, a great-granddaughter of Seckham, and as a result it has been po ible to piece together the outline ofhis varied career.' He was born on 25 October ,827,' He took his names from his grandparents, Samuel Seckham (1761-1820) and Susan Lipscomb (d. 18'5 aged 48).3 His father, William ('797-,859), kept livery stables at 20 Magdalen Street, Oxford,. and prospered sufficiently to retire and farm at Kidlington.5 The family came from Devon, where it is aid that Seccombes have occupied Seccombe Farm at Germans­ week, near Okehampton, since Saxon limes. Seccombes are still living there, farming. It is thought that Seckllam is the earlier spelling, but tombstones at Germansweek show several different versions. 6 It is not known how the family reached Oxford, but Samuel Lipscomb Seckham's great-grandmother Elizabeth was buried at St. Mary Magdalen in 1805.7 His mother was Harriett Wickens (1800-1859). Her grandfather and father were both called James, which makes it difficult to sort out which is which among the various James W;ckens' recorded in I The fortunate chance occurred when Mrs.

  • Screening Statement on the Determination of the Need for a Strategic Environmental Assessment
    Screening Statement on the determination of the need for a Strategic Environmental Assessment (SEA) in accordance with the Environmental Assessment of Plans and Programmes Regulations 2004 and European Directive 2001/42/EC for the North Hinksey Neighbourhood Development Plan 07/06/2018 SUMMARY In this screening opinion, Vale of White Horse District Council (the ‘Council’) determines that North Hinksey Neighbourhood Development Plan (North Hinksey NDP) does not require a Strategic Environmental Assessment (SEA) or Habitats Regulations Assessment (HRA) appropriate assessment. INTRODUCTION 1. North Hinksey Parish Council has requested that Vale of White Horse (VoWH) District Council ‘screen’ the North Hinksey Neighbourhood Plan, to determine whether there is a requirement for Strategic Environmental Assessment (SEA) and HRA appropriate assessment. This report presents the Council’s Screening Opinion. BACKGROUND 2. One of the basic conditions that a Neighbourhood Plan (NP) must be tested against is whether the making of the NP is compatible with European Union obligations, including requirements under the SEA Directive. The aim of the SEA Directive is: “to contribute to the integration of environmental considerations into the preparation and adoption of plans and programmes with a view to promoting sustainable development, by ensuring that an environmental assessment is carried out of certain plans and programmes which are likely to have significant effects on the environment.” 3. In order to decide whether a proposed NP is likely to have significant environmental effects, and hence requires SEA, it should be ‘screened’ at an early stage, i.e. once the plan remit and objectives have been formulated. 4. Screening is ‘Stage A’ in Government’s six stage approach to SEA for NPs.
