Page 1 of 26 AP18 Severn Estuary – August 2015 Purpose This evidence paper has been developed to provide some context as to the Forest of Dean District Council Allocations Plan (AP) and the Severn Estuary SSSI, SPA, SAC and Ramsar (referred to as the Severn Estuary European Site (SEES) in this paper). It provides further background information in supporting the Allocations Plan (AP) Habitats Regulations Assessment (HRA) in regard to potential recreational/disturbance impacts in the Lydney Harbour area. The Allocations Plan Habitats Regulations Assessment With regard to disturbance effects in the majority of cases the mitigation provided for in the Core Strategy were considered sufficient to address concerns for any potential adverse impacts. However the HRA screening identified that the quantum of proposed development in the Lydney area had, on a precautionary basis, the potential for likely significant affect alone or in combination on the SEES. However the HRA also identified that the potential impacts from disturbance to the Severn Estuary have to be set in terms of the whole of the amenities in the district. The Forest of Dean and Wye Valley Area of Outstanding Natural Beauty are a significant tourist attraction with many formal and informal recreation sites attracting large number of visitors and locals. The HRA found that a number of changes should be made to the Allocations Plan to ensure there were no potential significant adverse impacts of the SEES. These included avoidance and cancellation measures, including additional text in the section on Lydney and policy caveats, to demonstrate how adverse effects on site integrity will be avoided. If these amendments were made and embedded in the Allocations Plan (the changes were all subsequently made) it would be able to demonstrate that foreseeable risks have been identified and the plan has established an enforceable framework with the aim of preventing the risks. It was therefore assessed that the AP would not have adverse effects on the integrity of the SEES through disturbance. Section 1-3 of this report (below) provides additional context and needs to be read in conjunction with the AP and HRA. It should also be remembered the approach to the AP policies is on a precautionary basis. Section 3 specifically provides some additional context to specific sites and policies identified in the HRA where it was considered appropriate to include cancellation or avoidance requirements in the AP in regards to the SEES. As part of this evidence paper a report has been commissioned from GCER (Gloucestershire Centre for Environmental Records) broadly covering an area around Lydney Harbour and the SSSI Impact Risk Zones (IRZ), the full report is included in Appendix 1. In addition a local bird recorder has been contacted and a meeting held to assist in providing additional local context. This evidence is presented below in the section on baseline ecological information. Conclusions Page 2 of 26 AP18 Severn Estuary – August 2015 No direct impacts on the SEES have been identified. On a precautionary basis where AP polices /allocations were identified as having some potential for disturbance to the Severn Estuary the local site context and development policy proposals have been considered. In all cases it has been considered that cancellation and avoidance measures can be easily incorporated to remove the potential for disturbance to the SAC; bearing in mind the local site /policy context. At strategic level the spatial distribution of all the housing and employment allocations was considered. This was undertaken in the light of the general development requirements of the NPPF and Core Strategy policy 11. The conclusion of this assessment is that due to the cancellation and avoidance measures, local landscape context and the relatively small scale development proposals there would be no residual effects of the AP on the SEES. 1 The Councils validation checklist requires all ‘major’ development proposals to have completed a Preliminary Ecological Appraisal (CIEEM) as an ecological minimum for an application to be validated.

Baseline Information 1.1 Background to Lydney Harbour The following information is summarised from a number of web sources including: www.gov.uk/lydney-harbour (regarding docks), Lydney yacht club, Lydney Online and the Forest of Dean and Wye Valley Tourism Association. From Roman times through the industrial revolution and well into the 20th century Lydney Harbour has been in active use. The Severn Estuary is of national and international importance recognised by its statutory designations. It has one of the world’s greatest tidal ranges; the harbour has a significant history of exporting and as one of the UK’s major sea links to the rest of the world. The harbour was built to transport iron and later coal from the forest and was the last port on the Severn where sea-going boats could unload. The current canal and basin complex was built between 1810 and 1813. The new dock on the estuary was started in 1809 and opened in 1813. The outer harbour was completed in 1821. The final export of coal from the harbour was in 1960. The harbour carried on working up to the 1970s by importing logs for the manufacture of plywood at the factory at Pine End and was finally closed in 1977. In 1985 the harbour from the swing bridge downstream was scheduled as an ‘Ancient Monument’, due to the historic importance as a transport link for the Forest of Dean to the Severn. The swing bridge was designated a Grade II Listed Building in 1988 due to it being ‘a very good example of the direct and sturdy quality encountered in the functional tradition of quay-side design’. In 1998 the Lydney Docks Partnership was established to create a sustainable future for this Scheduled Ancient Monument. In 2003 they secured from the Heritage Lottery Fund towards restoring the docks. This was supplemented by further funding from the Environment Agency, English Heritage, Gloucestershire County Council, Forest of Dean District Council and Lydney Town Council. Since then the Environment Agency have undertaken extensive restoration and improvement works to the docks, these included: Restoring and enhancing flood defences running along the side of the dock. Automated metal-gates and associated mechanisms, in the outer dock and inner harbour. Dredging of the dock and harbour. Full refurbishment of dressed stonework on the walls and the floors of the docks. Improving access for all. Additional landscape works. The docks were re-opened in 2005 after the two year project to restore and enhance the docks area. A Local Action Group hopes to continue improvements; to extend the Yacht Club and to provide a cafe and toilets. The area earmarked for this small scale development has been highlighted in the Lydney Neighbourhood Development Plan (examiners version 2 May 2015), and included here in the section below on AP42. This area forms part of the larger area covered by policy AP 42.

The area discussed within this evidence paper covers the area surrounding Lydney Harbour and Canal Basin, running from the sea gates to main line railway station and the A48. One of the main areas discussed within this report in the sections below is New Grounds: an area of low lying pasture south of Lydney harbour between the estuary and the main line railway (and north of Alyburton Warth) there are no public rights of way across these fields. To the north of the harbour is an area of arable fields located between the estuary and Nass Court and Lydney Golf Course. This area is crossed by existing public rights of way: the land is higher than the harbour and estuary and is separated from the estuary by a woodland belt above Nass Cliff. The older industrial areas of Lydney are on the relatively flat and generally low lying land closer to the Severn Estuary. These industrial areas and Lydney Harbour are accessed by the Harbour Road. The Harbour Road is the only access to Lydney’s main line railway station as well as the Lydney Industrial Estate and various other business and properties, there is also access to Lydney Golf course. Two policy areas (AP45 and AP52) identified for recreational use are also located at the western end of the Harbour Road close to the railway station and the town of Lydney. 1.3 Green Infrastructure Within Gloucestershire an evidence base has been used to produce a series of maps showing the key areas of existing and potential green infrastructure (GI). This has informed the development of a map showing a vision for the strategic green infrastructure (GI) of the county – both existing and where it needs to be created or enhanced. The National Planning Policy Framework defines green infrastructure as: A network of multi- functional green space, urban and rural, which is capable of delivering a wide range of environmental and quality of life benefits for local communities. The Strategic Nature Areas identified in Gloucestershire’s Nature Map were a key element in determining Green Infrastructure blocks: the Strategic Nature Areas adjacent to Lydney are included within the GI blocks for the county. The Strategic Nature Areas (SNAs) of the Gloucestershire Nature Map identify landscape-scale areas where there is opportunity for both the maintenance and, crucially, the restoration/expansion of Priority Habitat. As such, they collectively represent an extremely useful aid to targeting nature conservation action. The SNA of relevance to the HRA and this evidence paper is SNA62 Alyburton and the SNA profile is attached in Appendix 2.
