Kent Wildlife Trust Sounds Alarm Over 1,500 Homes Planned Beside Sevenoaks Reserve

When Sevenoaks District Council's updated Local Plan was last covered on this site in June, the site west of Old Otford Road was flagged for 12,000 square metres of employment space. What's now actually landed in the plan's live Regulation 19 consultation is considerably bigger: a proposal for 1,500 homes, 12 gypsy and traveller pitches and a new community and leisure centre on land immediately north of Sevenoaks Wildlife Reserve, formally listed as site reference ST4-7. Kent Wildlife Trust is now actively campaigning against it, and urging residents to respond before the window closes.

The reserve itself is not a minor patch of green space. It sits on the Sevenoaks Gravel Pit Site of Special Scientific Interest, a designation that exists specifically because of what's there: more than 2,000 species recorded on the site, including protected and red-listed birds. Development of this scale immediately alongside a designation like that is exactly the kind of proposal conservation bodies are set up to scrutinise hardest.

Kent Wildlife Trust's objections go beyond the reserve's boundary line. The charity is concerned the development would weaken the wider landscape links connecting the reserve to surrounding countryside, isolating habitats that currently function as one continuous system rather than a fenced-off island. There's a water quality dimension too: part of the site sits on high flood risk and functional floodplain land, and the Trust warns that large-scale development nearby risks sending polluted runoff and sediment into the River Darent, a rare chalk stream, while reducing the natural capacity of the land to store water in the first place.

Perhaps the most concrete concern is the plan's own design: a proposed entrance running directly into the reserve, which the Trust says could expose sensitive habitat to disturbance from roughly 5,000 new residents without proper visitor management in place. Emma Waller, the Trust's Senior Planning Officer, put the underlying worry plainly: "Once these vital connections are lost, they are incredibly difficult to restore."

This is the Regulation 19 stage of the Local Plan process, which means the scope for residents to comment is narrower than in earlier rounds — responses need to focus on whether the plan is legally compliant and "sound," rather than proposing entirely different options. That's a real constraint, but it still leaves room to argue that a specific site allocation isn't sound given its impact on a designated wildlife site right next door. Residents wanting to respond can do so through Sevenoaks District Council's online consultation form or by emailing a written response directly, before the window closes on 17 September.
