Desk-Based Assessments (DBA)
Desk-Based Assessments are often submitted with the initial Planning Application, it can then be used to assist in the decisions of any required mitigation schemes.
Research of known heritage assets in the proposed development site and surrounding area, along with historical background and evidence from previous archaeological work in the vicinity provides the required information to assess the potential for archaeological remains which may be present within the proposed development site. It also assesses the possible impact that the proposed work will have on these remains.
The report is compiled when the available information has been assessed.
A typical example will include results from historical documentation, aerial photographs, maps, borehole logs and previous archaeological work carried out in the local area.
A Geophysical Survey may initially be requested in further assessing if archaeological work is required prior to development.
If further archaeological work is required, this may take the form of a Watching Brief, Trial Trenches or a Strip, Map and Record Evaluation, the DBA will also help with locating the areas to be monitored, positioning of trail trenches and identifying features during any excavation requirements.
Alternatively the DBA may show there are no potential archaeological remains present within the development area, and therefore possible that no further archaeological work would be required.
The decision for the need of archaeological work is made by the local Historic Environment Record office (HER)
