Local risks and emergency planning
- Coast: about 320 km of the council boundary is shoreline at mean high water, by our measurement (this includes tidal estuaries). Coastal flooding and storm surges are possible; the flood areas above include any coastal ones.
- Flooding: 57 flood warning areas and 33 flood alert areas overlap the council area (details above).
- Sussex Local Resilience Forum publishes a community risk register: the official list of emergencies that planners prepare for here.
- Hazards the register names include (our grouping of its wording): Flooding; Storms and severe weather; Heatwaves; Wildfires; Snow and low temperatures; Cyber attacks; Animal disease; Pandemic; Industrial and chemical accidents; Transport accidents; Outbreaks of infectious disease; Terrorism; Fuel shortages; Telecoms failure; Loss of water supply; Power cuts; Poor air quality; Drought; Space weather; Public disorder. Open the register for how likely and how serious each one is judged to be.
We list only what official sources say. We do not rate how safe or risky anywhere is.

How these figures were gathered
- Council links come from GOV.UK Local Links Manager, the list councils keep for GOV.UK. We opened each one on 2 November 2026; links that no longer worked are left out, and a few council sites blocked our automated check, which is noted beside the link.
- Area is our measurement of the ONS generalised (clipped to the coastline) boundary, so it can differ slightly from official area figures.
- Network operator shares are of land area, from the Energy Networks Association’s licence area boundaries; they are not customer counts.
- A flood area counts as overlapping if at least 1% of it lies inside the council boundary.
- A&E distances are straight lines from the centre point ONS gives for each built-up area to the centre of the hospital’s postcode. Travel distances and times will be longer.
- Water resource zones are listed when at least 1% of the council’s area falls inside them. The Environment Agency says the zone map is for mapping only, not for checking a property.
- Phone and broadband figures are Ofcom’s council-level predictions for January 2026. Mobile coverage uses Ofcom’s signal thresholds; an operator’s network counts if its predicted signal meets them. For a county council area they are our premises-weighted combination of its districts’ figures.
- Coastline is our measurement of the ONS boundary clipped to mean high water, where it is not shared with another council. It includes estuary shores, so it is longer than the open coast; we only mention it above 20 km.
- The hazard list is our grouping of the words the register uses: we list a hazard when its terms appear at least twice in the register’s text. It is not a rating of risk, and the register may cover more.
- Census figures are planning prompts, not risk scores. The household figure uses 66 and over, as the census tables do. For a county council area they are our sums of its districts’ census counts.
- Built-up areas are the largest by land area from ONS Built-up Areas 2022. Flood areas listed under a town are those whose official name includes it; a missing area does not mean a street will not flood.
