Appendix A – Allocated Sites

1. The following appendix provides information on the minerals and waste sites (listed alphabetically) that are allocated within the Plan:

Site Reference	Site Name	Location	Local Plan Authority	Proposal
WA 1	Berkyn Manor Farm	Horton	RBWM	Waste Management
WA 2	Horton Brook Quarry	Horton	RBWM	Waste Management
MA 1	Horton Brook and Poyle Quarry Extension	Horton	RBWM	Sand and Gravel Extraction
TA 1	Monkey Island Wharf	Bray	RBWM	Aggregate Wharf
MA 2	Poyle Quarry Extensions	Horton	RBWM	Sand and Gravel Extraction
WA 3	StubbingsCompound	Pinkneys Green	RBWM	Waste Management

2. The delineation of the site is shown by the red boundary. In the case of mineral extraction sites, it does not mean that working would extend to the site boundary as the allocation needs to include provision for buffer zones and mitigation measures. These will be determined through detailed site investigation, taking into account the development considerations for each site. Such measures will be covered by the planning permission, including the relevant conditions and / or legal agreements. It may also include provision for ancillary development such as plant, offices, access and weighbridge.

3. In the case of waste sites, types of waste activity that are considered suitable are provided. More detail on these activities is provided in Appendix B.

4. Development considerations are identified in the text accompanying each map in this appendix. They should be addressed alongside the other policies of the Plan. Development should be designed with appropriate mitigation measures, where applicable, to avoid or mitigate its impacts on the environment and local communities. Development considerations apply to minerals and waste developments in Central and Eastern Berkshire but may also include impacts that extend beyond the Plan boundary.

5. Development cannot be permitted if it may negatively affect the integrity of European protected sites. The development requirements for maintaining this integrity are identified with an asterisk (*) in the text and must be addressed.

6. The Plan does not specify how the development considerations may be addressed. This will be assessed at the planning application stage, which should present the most appropriate responses, which are likely to include detailed site appraisals and Environmental Impact Assessment (EIA). These will identify what effects the development will have, and how to tackle them. All assessment information and suggested mitigation measures should be clearly identified and form part of the pre-application discussions and consultation with communities.

7. For any development proposal at the sites identified in the Plan, all elements of the Plan need to be considered as well as the site-specific development considerations outlined in this Appendix.
