SSSI Impact Risk Zones (England)

The SSSI IRZs are a Geographical Information System (GIS) tool developed by Natural England to make rapid initial assessment of the potential risks posed by development proposals to SSSIs and those Special Areas of Conservation (SACs), Special Protection Areas (SPAs) or Ramsar sites that they underpin. They define zones around each site which reflect the sensitivities of the features for which the site is notified and indicate the types of development proposal which could potentially have adverse impacts and need further consideration. In certain locations they also include Natural England's statutory advice for certain development types. LPAs can use the SSSI IRZs to consider if a proposed development is likely to affect a terrestrial SSSI and those SACs, SPAs or Ramsar sites that they underpin and when to consult Natural England to seek advice. Where the SSSI IRZs include Natural England's statutory advice or indicate a risk is unlikely, LPAs can use the SSSI IRZs to instantly generate a formal consultation response. Add the SSSI IRZs to your own GIS using the Web Map Service (WMS) link or download from the dropdown menu above or the links below. Download the latest update in ESRI Shapefile format. Use the SSSI IRZs online on the MAGIC website. View the SSSI IRZs user guidance to learn how to interpret and use the SSSI IRZs. Alternatively, a training video is available that includes a step-by-step description of how to use the SSSI IRZs tool. For information on when LPAs must consult Natural England when considering development proposals refer to Planning and transport authorities: get environmental advice on planning - GOV.UK (www.gov.uk). For information on how developers can get advice from Natural England on planning applications refer to Developers: get environmental advice on your planning proposals - GOV.UK (www.gov.uk).
