Challenge

The Truro East Park & Ride facility in Cornwall aimed to create 1800 car parking spaces and spaces for coaches to reduce traffic entering Truro by 15%. The £9.6 million scheme was funded by the European Regional Development Fund (ERDF) Convergence Programme, the Housing Growth Point, the Regional Growth Fund (RGF), and the Local Transport Plan 3.

Cornwall County Council's design for the new facility focused on the importance of sustainability and enhancing and protecting the local habitat and landscape.

Planning limitations meant that the run-off from the site could not exceed pre-development levels. The Council decided to meet this requirement in part though porous paving.

Solution

ABG supplied a range of cost-effective SuDS-compliant geosynthetic solutions for the site.

Fildrain was used to provide subsurface drainage in place of traditional pipe and stone solutions. This minimised the impact of the development on the surrounding area, including a number of protected trees.

Fildrain was also used for the perimeter of the car park and access routes. This required a much reduced dig out and less site material to dispose of. Imported fill was also reduced.

Approximately 17,000m2 of Sudspave 40 was selected to provide stabilised gravel and grass surfaces for the general parking bay areas. An appropriate bedding layer was placed underneath and a ‘DOT Type 3’ free-draining sub-base layer. Proprietary white Sudspave markers were incorporated to delineate individual parking bays.

Bus turning and parking areas were surfaced with heavy-duty Truckell 80. Terrex NW9 geotextile provided a combined separation and treatment function.

Outcome

This major Park & Ride project was successfully completed.

As well as satisfying the requirement for a ‘natural’ finish to the surfacing, Sudspave and Truckcell provided an effective stormwater treatment solution whilst also reducing the overall depth of construction. Both are highly effective source control systems that manage stormwater runoff in accordance with best practice guidance – including the entrapment and biodegradation of pollutants.

Incorporating geogrids and geotextiles within pavement construction layers can further reduce the overall construction depth by up to 50%, delivering reduced risk, significant commercial benefits and shortening contract completion times.
