Martello Lakes, Hythe

Project overview

Land-forming earthworks and remediation – 1.8 million cubic metres of material are being moved as part of a new land-forming operation. This involves relocating the existing quarry lake, reshaping the large stockpile mound and using imported material to create a suitable development platform for a new residential and commercial development. During this process, contaminated material was removed from some areas. Major works commenced in 2014 and are due to be completed by the end of 2030.

Ecology

To enable large-scale earthworks to begin, ecology and habitat clearance was undertaken across various areas in a timely and carefully planned manner. Reptile translocation was carried out for common lizards, slow worms and grass snakes. Licences from statutory bodies, including Natural England, have been obtained for these works.

Two access points into Martello Lakes Development

The primary access was formed with a four-arm Section 278 roundabout off Dymchurch Road. The works involved diverting an Affinity Water strategic main, while two new high-voltage cables were designed to be accommodated within the new roundabout. A secondary access was formed to the east, also off Dymchurch Road, as a non-signalised T-junction.

Foul Water Drainage

Two foul-water pumping stations have been constructed. The primary station was designed to serve 650 properties, while the secondary pumping station was designed to serve 400 properties. Both discharge into the existing Southern Water drainage system off Pall Marsh Avenue.

Surface Water Drainage

The newly formed lake receives all surface-water run-off from the development parcels at a statutorily approved discharge rate. With no requirement to attenuate storm flows before discharge into the lake, the proposed SuDS strategy is instead focused on managing water quality, maximising ecological benefit and creating a positive amenity feature for future residents.

Informal and Formal Open Spaces

The development’s most extensive area of open space is focused around the reclaimed Nickoll’s Quarry, which has formed Martello Lakes. Extensive earth shaping will create two distinct water bodies, each with its own character and use. The lakes will provide natural habitats for water birds and other aquatic and marginal fauna. Marginal planting, including reed beds and nesting areas, will contribute to greater biodiversity across the site and provide ecological interest for visitors using the new coastal path that meanders through the development.

New Stagecoach Bus Route

A dedicated bus route with real-time information systems runs through the centre of the development via the proposed new local centre and will ultimately connect directly to Hythe town centre.
