A–G grade for BA1: not assessed at district level. A complete postcode is needed to check live utility and road incidents and listed emergency-care distance. A grade appears only when all three inputs can be scored. How the full-postcode grade works.

Local flood evidence for BA1

Recorded flooding

It also documents historical flood marks at Widcombe Bridge and explains that the 1960 event helped prompt later defence works. Historic water levels describe conditions before those works.

Data & Preparedness Score 6/6

All three evidence checks meet the highest level for this report. The score describes the evidence available in this report. It does not measure risk, safety or personal readiness.

Warning coverage 2/2: A named official warning or alert area is documented locally. Check the mapped boundary for your address.
Official guidance 2/2: Local authority or regional preparedness guidance is linked below.
Data completeness 2/2: Council density is available. A local flood record is documented.

How the district score is calculated

Warning coverage earns 2 points for a documented local warning area, 1 for an official service link and 0 when no source can be identified. Guidance earns 2 for a local authority or regional preparedness link, 1 for UK guidance and 0 when neither is available.

Data completeness earns 2 points when council density and a documented local flood record are both available, 1 for either and 0 for neither. The three scores are added. The number or severity of current warnings does not change the score.

How the nine indicators apply

A district prefix covers many full postcodes. This page has no live A–G disruption grade and does not assess war or nuclear risk. Enter a complete postcode above to see the nine-indicator breakdown for its returned location.

Can contribute to a full-postcode grade: Infrastructure: matched electricity or water incidents where covered. Medical resources: straight-line distance to a listed emergency department. Road access: nearby active TfL events where covered. Missing feeds are excluded, not scored as zero.
Can be shown, without a risk score: Wind direction and speed, one-hour rainfall forecast, and elevation with sampled local relief. These do not establish exposure to a particular incident or protection at a building.
No verified postcode-level assessment: Military targeting, building structure and designated shelter availability. A postcode prefix cannot supply these details.
