Chapter 2. Evidence and Analysis SITE AND CONTEXTUAL ANALYSIS

South Downs Way

Existing structures

Most buildings contain asbestos. Buildings, conveyors, rail tracks, and surfaces contribute to the cultural industrial character of the site. Buildings have potential for birds/bats habitat.

Ground contamination

The central area is heavily constrained by substantial deposits of concrete kiln dust and is the site of a former lagoon. New buildings would require significant decontamination and complex foundations.

Tidal/river flood risk

The River Adur is tidal and when extreme events happen, the valley floods. Existing defences along the riverside prevent the site from flooding, but climate change could change this.

Surface water flooding

The A283 embankment prevent from most runoff water to flow down to the river. Chalk is permeable, but there are areas of standing water due to large extent of impervious surfaces (e.g. buildings, yards).

Shade

Due to the topography, areas along the southern boundary/cliffs are in the shade, except in Summer months. Contrarily, large areas are exposed to sunlight, glare and overheating.

Cliffs

Downs Link

Trees and woodland

Large wooded areas along the A283 and trees along the riverside boundaries.

Shrubs and hedgerows

Rich and varied vegetation has grown within the central area. Hedgerows form most field boundaries.

Chalk grassland

Native chalk grass and wildflowers are a priority habitat in the South Downs.

Scarp cliffs evidence the quarrying industries and are of geological and ecological value. There is a risk of erosion/ collapse but cliffs offer opportunities for long distance views. Birds nest in some cliffs.
