DBS Supported BAM Nuttall Ltd (BAM) with Remediation Verification of a large site know as Peters Village. Peters Village is located in Wouldham, Kent, and covers a total area of approximately 35.05 hectares. The site is located next to the River Medway.
The site had various uses historically comprising a chalk quarry, agricultural land and a cement works (Peters Works). Redevelopment proposals comprised a change of use to residential; the overall scheme comprised of three individual village areas (Village 1, Village 2 and Village 3) that were subdivided into a total of fifteen individual development parcels for housing development, community facilities and landscaping to create a large new housing project with the ethos of creating a new connected community with a village feel.
Ancillary works were also completed by BAM including installation of a new sheet piled river wall and corresponding anchor wall, and the construction of a new road bridge across the River Medway to link the site to the villages of Holborough and Halling, including fast train links to London and access to the M20 and M2 motorways.
The former cement works area of the site required remediating for a change of use, areas of the site outside of the former cement works were subjected to a cut and fill exercise only to create development platforms, with surcharging of peaty deposits and the installation of band drains. The cement works was operational from 1858 until its closure in 1926. It is understood that during the height of cement production in the late 1800s, the cement works employed 1,000 people and operated a large fleet of barges which transported its product across the river to the local rail/road terminal.
Over the years the site underwent progressive development, with the addition of various industrial operations including a railway depot, numerous factory buildings, and its use by Chatham Dockyard for stores etc. In later years it was utilised for pre-cast concrete manufacture, vehicle storage and maintenance, plant hire and a variety of other small scale industrial processes.
The principal objective of the remediation scheme was therefore to render the site suitable for residential use following its industrial past in the former works area, and to undertake earthworks across the overall site to create development platforms within the 15 individual development parcels.
The site was subject to a tiered process of ground investigation and risk assessment by others, with a Remediation Method Statement produced detailing how site redevelopment was to proceed.
The LPA was Tonbridge & Malling Borough Council (TMBC) and pre-commencement conditions for contamination were attached to the planning consent.
DBS supported BAM with the delivery of Remediation Verification and reporting for each land parcel of the site to support planning condition discharge; as part of this work we engaged closely with BAM and liaised frequently with TMBC as the remedial works progressed.
Remediation was undertaken as a bespoke exercise within each land parcel within the former works area but briefly comprised of a site turnover to remove, crush/screen and re-use buried hard materials as part of a sustainable remediation strategy, capping of old wells, removal and treatment of soils ex situ for re-use, and in situ treatment of groundwater.
DBS supported BAM to achieve planning condition discharge on remediation and to successfully deliver the site for residential use. Report preparation/verification was completed for fifteen individual land parcels validated independently of each other and released to market by the site owners to create a very prestigious new village community with excellent transport links for the south east of England.
It was a privilege to work on such a large ambitious project with a sustainable ethos to provide much needed residential housing and community facilities for the south east of England, returning a site to beneficial use with excellent sustainable transport links.
