Project: Wakefield East, Wakefield
Type: Residentially Led Mixed Use Development

Scope of Project

This 150 hectare site, located to the east of Wakefield town centre and situated alongside the River Calder and the Aire and Calder Navigation was identified by Wakefield Metropolitan Distict Council as a potential development site within its Site Specific Proposals Document.

The proposals were for a mix of residential, educational, industrial and commercial premises, accompanied by a new relief road and rail and river crossings.

The Environment Agency (EA) flood map indicates that the site is located in Flood Zones 1, 2 and 3.

Weetwood was appointed to prepare a Flood Risk Assessment for submission as evidence to support the sites promotion and inclusion in Wakefield MDC’s Local Development Framework.

 

What We Did

We undertook a site specific Flood Risk Assessment (FRA) in accordance with Planning Policy Statement 25: Development and FLood RIsk (now superceded by the National Planning Policy Framework) and Wakefield MDC's local drainage policy requirements.

Flood risk from all sources was assessed and a package of mitigation measures developed based on flood risk and proposed land use.

We prepared an illustrative, site-wide surface water drainage scheme based on sustainable drainage principles. The scheme was designed to accomodate phased development of the site without compromising the attainment of site wide surface runoff management goals. The scheme demonstrated that the site could be developed without increasing flood risk.

We also advised on the minimum soffit level required for the new River Calder crossing, based on hydraulic model output of the River Calder.

Outcome and Value Delivered

By demonstrating that the site could be developed in accordance with national and local planning policy, Weetwood was able to show that the site was achievable in terms of flood risk. This helped support the successful promotion of the site.

As a result, Weetwood has been retained to contribute to the emerging Development Brief for the site and to prepare a Flood Risk Assessment in support of the first planning application. Weetwood's role has also been expanded to include the development of a potable water and foul water assessment.

The project demonstrates our ability to successfully deliver flood and water management solutions for large and complex developments.
