One of the conditions for development of the site is that an equivalent site be created elsewhere, the so-called Ecological Mitigation and Compensation.

The work to clear the Tufa Field is being undertaken by Ethos Environmental Practice, contracted to BANES. The Government Agency Homes England has provided a £700,000 grant towards the costs. Estimates put the cost so far at about the same, a total expenditure of between £1.5m and £2m.

There is no equivalent site in the area, so there is an intention to create a site at Pennyquick, about 2 miles away. The artificial creation of a tufa flush site has never been attempted before, so there is no guarantee of success and the site chosen has it’s own problems, including the potential for contamination of Newton Brook from the former Pennyquick Colliery and Quarry workings on the site.

After the 1942 blitz, much of the demolished material was dumped here, with unknown content, so any disturbance will need to undertaken with great care to avoid downstream contamination.

There is no date for the availability of this site or how it will be monitored to measure success or otherwise.
