What the plan says about it
The site occupies a prominent position in SIEA1, and is well linked to the A2690 Queensway with strong links to both the A259 (Brighton-Ashford) and the A21 (London). It is one of a group of three small development plots. The first, NX1 immediately to the south, was developed as a row of small business units. This site is capable of delivering additional small units. The site also has strong potential to accommodate low carbon technologies as part of any development, including solar PV.
The site is in close proximity to an area of Ancient Woodland to the East, and Local Wildlife Sites to the South East and South West. The site itself is sloping with areas of dense scrub. These areas of wildlife sensitivity and the site itself should be thoroughly surveyed as part of the Ecological Constraints and Opportunities Plan (ECOP), to identify constraints. Any development proposal must seek to avoid or minimise impact on these areas during both the construction and occupation phases of the development. The introduction of pollutants to the highly vulnerable groundwater aquifer to the South of the site should likewise be avoided during both phases.
The rest of the plan's explanation (4 more paragraphs)
There is potential to create integrated ecological and surface water management interventions, including SuDS, with sites PX and NX2, building upon those already delivered through the development of site QX. Due to the site sitting within the Impact Risk Zone (IRZ) for the Marline Valley Woods SSSI and Combe Haven SSSI, Natural England should be consulted at the earliest possible stage.
A lighting plan will be required due to the close proximity to areas of wildlife sensitivity and must demonstrate how steps have been taken to reduce light spill that may impact on these areas. An arboriculture plan must also be provided to set out how existing trees will be either integrated into the proposal, or their loss will be compensated for. The site has a natural tree boundary to the West that should be retained and enhanced where possible. The ECOP, lighting plan and arboriculture plan can all form part of the same document if appropriate.
The site slopes to the South and undulates throughout. A fault line runs through the Southwest portion of the site. Due to these characteristics, investigations of ground behaviour and land stability should take into account the hydrology of the site, the strata and the potential for subterranean water conduits. A detailed stability report will be required and should inform any potential SuDS design for the site.
A Transport Assessment and Travel Plan will be required, setting out a vision led and validate approach to development. The existing access off Sidney Little Road is configured to serve both the existing units and those still to be built on this site and on site NX2, however improvements to better support access to the site through public and sustainable transport may be required. Development proposals will need to show consideration of the transport impact along The Ridge.
What a planning application here would have to do
- be designed in a way that contributes positively to the intensification of SIEA1
- Be supported by an Ecological Impact Assessment (EcIA) and include an Ecological Constraints and Opportunities Plan (ECOP) and incorporate appropriate conservation and mitigation measures as recommended by the EcIA. The ECOP must make specific reference to the presence of the adjacent Ancient Woodland, the results of site surveys of ES4 itself, and to other nearby areas of wildlife sensitivity.
- include a lighting plan to minimise light spill to nearby areas of wildlife sensitivity, including nearby Ancient Woodland and Local Wildlife Site
- include boundary landscaping appropriate to the setting and taking into account existing trees and vegetation
- provide an Arboriculture Plan that demonstrates how existing trees on site and at the western boundary will be integrated into the development
- ensure drainage schemes, including SuDS, are appropriate for the site and take into account Impact Risk Zones, the strata, potential for subterranean water conduits and groundwater pollution vulnerability. Hydrological and hydrogeological monitoring should inform the drainage plans for this site
- include appropriate active and sustainable travel infrastructure, maximising walking, wheeling and cycling links, as well as appropriate access to public transport
- be supported by a Transport Assessment and Travel Plan. The Transport Assessment must take account of the site's proximity to The Ridge. Proposals must also indicate how the conclusions and recommendations of the Assessment have been incorporated within the development, and include arrangements to implement a monitor and manage approach to determine whether further transport interventions are required; h. investigate the impact of ground behaviour and land stability incorporating remediation or mitigation measures as appropriate
- investigate the potential for contamination within or effecting the site, and incorporate remediation or mitigation measures as appropriate
- be designed to avoid or, where this is not possible, mitigate the impact of potential pollution and environmental hazards to the environment, occupiers and neighbours
- provide policy compliant green and blue infrastructure within the site
