Conservation and heritage on this street

None of the town’s 18 conservation areas reaches De Cham Avenue as mapped.

Measured along the street’s line against the council’s boundaries. Whether a particular building is inside depends on where the boundary runs: each area’s page on the council’s site has its map. All 18 conservation areas

The council’s Article 4 direction on houses in multiple occupation covers the whole town (in force since 2 July 2012): turning a house into a shared house for three to six people needs planning permission. The council’s page ↗

Flood zones, the coast and protected nature on this street

We place an application by the street in its address, so these say where De Cham Avenue runs, not where the site’s boundary is. The application’s own documents on the council’s file show the site.

Flood zones

None of De Cham Avenue’s line is in Flood Zone 2 or 3 on the Environment Agency’s flood map for planning. In the Agency’s words: “This means a site in flood zone 1 could still flood now or in the future.”

A street’s line is not an address. For a particular address, use the Environment Agency’s Check your long term flood risk ↗; for a planning site, its Flood map for planning ↗. Flood warnings in force now are on Live now.

Protected nature

No Site of Special Scientific Interest, Special Area of Conservation, Local Nature Reserve, ancient woodland or country park is within about 100 m of De Cham Avenue’s line, and it is outside the High Weald National Landscape. Protected nature in Hastings

If you think work doesn’t match what was approved

The council’s planning enforcement team looks into building work or a use that may not have permission, or may not follow the approved plans or conditions. Its page explains how to report it and which cases it deals with first: planning enforcement on the council’s site ↗

Our planning record starts on 21 April 2026, from the council’s weekly lists of new and decided applications. We list the site, the proposal, the dates, the decision, the comment counts and a permission’s conditions. We never copy a commenter’s or an individual applicant’s details; an applicant is named only when it is an organisation we can match exactly to a council, a registered charity or a company on Companies House. Planning is decided by the council, not by us.
