The study area is from Land's End to the county boundary between Devon and Cornwall/City of Plymouth in the east, including a small part of Devon that was excluded from the South Devon Coast RCZAS. The broad aims of the project are to: 1) Provide an enhanced Historic Environment (HER) and National Record of the Historic Environment (NRHE) record for coastal and near-shore marine heritage assets (including palaeoenvironmental deposits), to a nationally agreed common minimum data standard, in order to permit an improved curatorial response to strategic coastal and marine planning or management initiatives at a national and regional level; 2) Provide a factual basis for the initial curatorial response to individual applications for commercial developments or schemes, in advance of more detailed evaluation and mitigation related to Environmental Impact Assessments (EIAs) and/or planning applications; 3) Enhance public understanding and enjoyment of coastal and maritime heritage; and 4) Assist Local Authority curatorial archaeologists in development control. This component of the RCZAS comprises a Desk-Based Assessment of readily available sources (i.e., sources not requiring primary research) only. Outputs of the project, which is due for completion in September 2018, will include a widely disseminated report, a GIS database for provision to Historic England, the Cornwall and Scilly HER, the Plymouth City HER, the Devon HER and the Archaeological Data Service (ADS), and a project design for the Phase 2 Field survey.
