Yes, though not from any river. None of the town is in the river-and-sea flood zones. About a fifth of its postcodes still come up high on at least one flood measure. The trouble is rain with nowhere to go. A ridge-top town that floods from the sky has had its risk decided by drains and gradients rather than by the Roding or the Lea.
The Environment Agency's river-and-sea mapping puts 0% of Epping's postcodes in flood zone 3, the highest-probability band, and 0% in flood zone 2, the medium-probability fringe beyond it. Epping stands on a ridge between the Roding and Lea valleys, with both rivers downhill and out of reach.
Surface water is a different matter. With the rivers ruled out, the risk this town carries arrives when heavy rain lands faster than the ground and the drains can take it. Put the exact address into the Environment Agency's surface-water map, because that layer, and no river map, is the one that describes Epping.
The Environment Agency's climate-adjusted zones, which extend the river-and-sea bands to allow for a wetter future, also cover 0% of the town. That forward look only models rivers and the sea, so it says nothing about the streets that collect rainwater.
Insurers read surface-water mapping alongside the river zones, so a home outside every flood zone can still cost more to cover if its postcode is flagged. "Outside the flood zones" on a set of particulars is true in Epping and answers a question about the wrong kind of water.
Across all of Epping's postcodes, counting any of several measures including surface water, about 21% rate high on at least one, another 21% medium and 52% low. A postcode only needs one measure to flag it. The risk is spread unevenly across the town, and the street a home is on matters more than the town's name.
Whether anything stands between the water and the house is a question Epping hardly has to ask. The Environment Agency's modelled flood extents put 0% of postcodes in a high-risk area without defences and 0% in one with defences, because the rivers those defences guard against do not reach the town. "Defended" would only ever mean a defence appears in the model, and here there is nothing for it to defend.
The Environment Agency's historic flood outlines cover none of Epping. Its separate list of recorded events holds seven, the most recent dated 1987 and put down to local drainage and surface water. No mapped history is reassuring, though records only capture the floods somebody wrote down.
Epping's flood risk is a real weakness that comes from rain and drainage, and a buyer's exposure depends on which fifth of the town's postcodes they end up in.
