Advice
In some instances, bird species that are associated with SPAs and some Ramsar sites may rely on non-designated habitats beyond the European site boundaries, and so could be vulnerable to activities occurring outside the designated site itself. Land within 10kmof an SPA, or a Ramsar site designated for its bird populations, is therefore considered to be of a potentially sensitive nature (due to its proximity to the European site) such that mitigation and/or alternative siting may be required by authorities further considering HRA issues for specific project-level operations. The European sites potentially vulnerable in or near this block are Arun Valley Ramsar, Chichester and Langstone Harbour Ramsar, Pagham Harbour Ramsar, Chichester and Langstone Harbours SPA, Pagham HarbourSPA, Arun Valley SPA.- Coastal or marine habitat features could be vulnerable to any changes in coastal processes that occur due to activities occurring along the coastline. Land located along the coastline (i.e. within 1km of the mean low water level), and which is also within 10km of a European site with coastal habitats, is therefore considered to be of a potentially sensitive nature (due to its potential connectivity to a European site) such that mitigation and/or alternative siting may be required by authorities further considering HRA issues forspecific project-level operations. The European sites potentially vulnerable in or near this block are Chichester and Langstone Harbour Ramsar, Solent Maritime SAC.- Bat species usually rely on non-designated habitats beyond the European site boundaries (bats can commute and forage for many kilometres beyond their core habitat), and so could be vulnerable to activities occurring outside the designated site itself. Land within the 10km of an SAC designated for its bat populations is considered to be of a potentially sensitive nature (due to its proximity to the European site) such that mitigation and/or alternative siting may be required by authorities further considering HRA issues for specific project-level operations. The European sites potentially vulnerable in or near this block are Singleton and Cocking Tunnels SAC.- Some of European site interest features (e.g. birds species; fish; marine mammals) are potentially sensitive to noise or vibration effects associated with Stage A activities (as well as Stage B, C and D activities). Land within approximately 1km of a European site supporting noise or vibration sensitive features is considered to be of a potentially sensitive nature (due to its proximity to the European site) such that mitigation and/or alternative siting may be required by authorities further considering HRA issues for specific project-level operations. The European sites with features potentially vulnerable to this in or near this block are Arun Valley Ramsar, Chichester and Langstone Harbour Ramsar, Pagham Harbour Ramsar, Chichester and Langstone Harbours SPA, Pagham Harbour SPA,Arun Valley SPA.

  1. Comment from Dr Jill Sutcliffe:
    Regarding block SU90a if Pagham Harbour is considered to be affected then need to take the newly constructed Medmerry site ie to west of Selsey, coastal realignment site, connected to the sea Sept 8th 2013. Both Pagham and Medmerry are managed by the RSPB. There is a regionally important population of rare and declining Water Voles on the Manhood Peninsula ie the land to the south of Chichester and which contains both Chichester and Pagham Harbours plus the new Medmerry site + 4 local Wildlife sites including the Chichester Canal etc.
