| Abstract: |
This archaeological desk-based assessment has been commissioned by Mott MacDonald Bentley, on behalf of Yorkshire Water, to assess the likely historic environment impacts of a new gravity sewer from Flamborough Village Sewage Pumping Station (SPS) at approximate National Grid Reference (NGR) TA 522560 469948 connecting to an existing rising main east of the Scheduled Dane’s Dyke at NGR TA 521550 470644. The works involve the replacement of the eastern section main with a new gravity sewer still discharging at the existing SPS. The new gravity sewer involves the provision of a buried pipe and fifteen manholes located where the pipe changes direction. A cut trench will be required to install the pipe and a construction easement of 20m from the centre line of the pipe will be required for stockpiling material.
This archaeological DBA and associated walkover survey identifies the potential for buried archaeological remains to exist within the proposed development area and their likely heritage significance. The report will then go on to address how this significance will be affected by the rising main replacement. Built heritage assets are explicitly excluded from this assessment due to the nature of the proposed works, as there will be no permanent above ground works which would impact on the significance of built heritage assets. No known non-designated heritage assets are recorded on the Humber Historic Environment Record within the route of the rising main replacement. However, during the site walkover an area of extant ridge and furrow was identified in a field immediately west of Flamborough Village and possible field boundaries of uncertain date have been identified on LiDAR imagery in the most northern field where the rising main replacement runs through.
The rising main replacement route also lies within an area of known prehistoric and Roman activity, common with many parishes in the East Riding of Yorkshire. The Scheduled Bronze Age Dane’s Dyke runs on a north to south alignment only 89m west from where the new rising main replacement route will be connected to the existing rising main. The dyke effectively cut off the Flamborough peninsula on its eastern side which was naturally defended on all sides by the steep chalk cliffs of the coastline. This area would have been large enough to support a sizeable community during the Bronze Age, Iron Age and probably Roman periods and it is therefore considered that the potential for further remains from these periods within the rising main replacement route is moderate. Similarly, evidence exists within the rising main replacement route for medieval or post-medieval agricultural land management features. Therefore, works associated with the rising main replacement route have the potential to impact on known as well as unknown archaeological remains.
Following consultation and agreement with Humber Archaeology Partnership (HAP) it is recommended that Geophysical Survey be undertaken across the full length of the replacement rising main route using a 60m wide corridor from its centre line to archaeologically evaluate the proposed development. The 60m wide corridor will allow for sufficient data to be acquired that if significant or substantial archaeological remains are identified in certain sections of the rising main replacement route that the route can be diverted or realigned to preserve these remains in-situ. The Geophysical Survey will also help to identify potential future stages of archaeological evaluation or excavation where the rising main replacement cannot be moved and archaeological features are present. The Geophysical Survey should be undertaken in accordance with a Written Scheme of Investigation (WSI) to be agreed in advance with HAP. Further consultation should be undertaken with HAP following completion of the Geophysical Survey to discuss the results and determine further archaeological work. |
