Historic Environment Action Plan the Undercliff
Directorate of Community Services Director Sarah Mitchell Historic Environment Action Plan The Undercliff Isle of Wight County Archaeology and Historic Environment Service October 2008 01983 823810 archaeology @iow.gov.uk Iwight.com HEAP for the Undercliff. INTRODUCTION This HEAP Area has been defined on the basis of geology, topography, land use and settlement patterns which differentiate it from other HEAP areas. This document identifies essential characteristics of the Undercliff as its geomorphology and rugged landslip areas, its archaeological potential, its 19 th century cottages ornés /marine villas and their grounds, and the Victorian seaside resort character of Ventnor. The Area has a highly distinctive character with an inner cliff towering above a landscape (now partly wooded) demarcated by stone boundary walls. The most significant features of this historic landscape, the most important forces for change and key management issues are considered. Actions particularly relevant to this Area are identified from those listed in the Isle of Wight HEAP Aims, Objectives and Actions. ANALYSIS AND ASSESSMENT Location, Geology and Topography • The Undercliff is identified as a discrete Landscape Character Type in the Isle of Wight AONB Management Plan (2004, 132). • The Area lies to the south of the South Wight Downland , from which it is separated by vertical cliffs forming a geological succession from Ferrugunious Sands through Sandrock, Carstone, Gault Clay, Upper Greensand, Chert Beds and Lower Chalk (Hutchinson 1987, Fig. 6). o The zone between the inner cliff and coastal cliff is a landslip area o This landslip is caused by groundwater lubrication of slip planes within the Gault Clays and Sandrock Beds.
