Southend-on-Sea LPA BNG

Southend-on-Sea, a unitary authority in Essex on the north bank of the Thames Estuary, is a predominantly urban Local Planning Authority (LPA) with a strong coastal character and important natural heritage. Covering approximately 41 square kilometres, the borough includes the city of Southend and several distinct neighbourhoods such as Leigh-on-Sea, Westcliff, and Shoeburyness. Despite its dense development, Southend features ecologically rich coastal, estuarine, and green space habitats.

​

Southend-on-Sea City Council supports the delivery of Biodiversity Net Gain (BNG) in line with the Environment Act 2021. Most new developments are required to deliver at least a 10% net gain in biodiversity through on-site habitat creation or enhancement, or through the use of off-site biodiversity units.

​

The borough lies within the Greater Thames Estuary National Character Area, which is characterised by intertidal mudflats, saltmarshes, grazing marshes, and coastal grasslands. Several designated sites, including Sites of Special Scientific Interest (SSSIs), Ramsar wetlands, and Local Wildlife Sites, are located within or adjacent to the LPA boundary, adding to the sensitivity and opportunity for meaningful BNG delivery.
