A specialist county contractor has been shortlisted for five awards at this year's Brownfield Briefing Awards.

Sanctus, based in Quedgeley, is a remediation contractor offering solutions for issues associated with brownfield land developments.

It has been shortlisted for:

• Best Public Sector/Not For Profit Lead Project - The Severn Rivers Programme, Cinderford
• Best Project Preparatory Work - Mayfield School, High Resolution Site Characterisation, Portsmouth
• Best Application of Remediation Technologies - Meadow View, Wheathampstead
• Best Re-use of Materials - Seven Stars Road, Oldbury - A Phoenix from the Floods
• Best Young Brownfield Professional - Emily Cooke

The Severn Rivers Programme is working in partnership with the Severn Rivers Trust and Gloucestershire Wildlife Trust. Sanctus was asked to help advance a programme of river restoration, barrier removal and sensitive environmental enhancements.

The £250k programme addresses five individual barriers to fish: making more than 20 kilometres of river accessible to salmonids, lamprey species, allis shad, twaite shad and critically endangered eel populations. In addition, approximately two hectares of enhanced spawning ground and valuable new terrestrial and aquatic habitat will be created.

The programme spans two locations - the Cinderford Brook flowing through the Forest of Dean before entering the River Severn near Blakeney and the River Frome at Ryeford.

The project includes removal of weirs and safe capture and relocation of any fish in the area of the works. Native white clawed crayfish in the area required a dedicated mitigation strategy. Before works can begin, each weir location will be surveyed, individual animals captured, identified and temporarily relocated outside of the working area.

A stand of invasive Japanese knotweed within the works area has been completely eradicated, allowing the recolonisation of native species, helping improve the overall biodiversity and ecological potential of the valley.

Richard Stockdale, Sanctus environment director, said: "It's an absolute privilege to be deliver these works in partnership with the Severn Rivers Trust and Gloucestershire Wildlife Trust, who are actively doing so much to improve the natural environment in and around Gloucestershire."

The virtual award ceremony will take place in November.
