ZE1 Flood Risk Data

ZE1 is a UK postcode district covering part of Lerwick, Shetland Islands. LocalRisk has flood, heat, air and ground-stability data for 328 postcodes in ZE1. The district runs to the UK coastline.

2.4% of postcodes in ZE1 fall into SEPA's high flood-risk band - below the UK average of about 7%. The band reflects the highest flood risk within each postcode; some properties may face little or no direct flood risk. Two postcodes a few streets apart can land in different bands; what drives the gap is elevation, distance to the nearest watercourse, and how the surrounding drainage performs in heavy rain. The postcode list below links to the full address-level reading for each postcode in ZE1.

Annual mean PM2.5 for the council area covering ZE1 is 3.2 µg/m³ - close to the World Health Organisation guideline of 5 µg/m³. Postcodes within 200 metres of an A-road or major junction routinely run higher during weekday rush hours than residential streets two roads back.

Ground stability in ZE1 follows the underlying geology more than the postal boundary. The British Geological Survey GeoSure dataset maps clay shrink-swell risk on a 50-metre cell, and properties on the same street can sit in different bands where a clay seam ends mid-road. A postcode-level check picks up that variation.
