The City East Hydrogeological Landscape (HGL) is characterised by low terrace landforms adjacent to Launceston's central business district (CBD) and by landslide deposits in the south east. This HGL is located east and south-east of the CBD of Launceston. This is an area of moderate rainfall (680 mm). it has low-lying terraces in the west and north-west adjacent to the Launceston CBD and Invermay HGL, and rises steeply in the east (e.g. the Lawrence Vale area) to the ridge crest at High Street.

Typical lithologies for this HGL are terrace deposits and Quaternary to Recent poorly-consolidated clayey silt, silt, sand and some gravel on low terraces and landslide colluvium over sedimentary rocks in more elevated areas. The landscape consists of terrace landforms (typically up to 20m) in the west and north-west, and an arcuate ridge with moderate to steep slopes in the east.
