Work is underway on the second element of a £4m flood prevention scheme in Birmingham, being carried out by Team Van Oord on behalf of the Environment Agency.
The works are being carried out in two phases – Selly Park North and Selly Park South – and when complete will significantly reduce the risk of flooding from Bourn Brook, a tributary of the River Rea, for hundreds of local homes and businesses.
Work is well underway on the Selly Park South flood defence scheme which comprises the construction of an embankment and a pile cladded wall to prevent water from overtopping the left bank of the River Rea, and creation of an area to store water during storm events upstream of the Dogpool Lane Bridge.
Downstream of the bridge new reinforced concrete walls will be constructed to protect the properties directly affected by the works, which commenced in September 2016 and are scheduled for completion in autumn 2017.
Under the Selly Park North scheme, which has been ‘fast tracked’ by the Environment Agency, the existing ground level will be raised at the three-acre site of the former BBC Sports and Social Club at Pebble Mill – an area which has previously been unusable in planning terms due to its flood status.
A flood relief overflow channel off Bourn Brook will further reduce flows to and under the Pershore Road Bridge. From here, a new tunnel will be constructed to form an underground flood relief culvert which will allow a second flood water route passing under the Pershore Road to the River Rea, thereby completing the flood mitigation scheme.
The scheme’s design was produced by Calthorpe Estates working closely with the Environment Agency, Birmingham City Council, Team Van Oord and other stakeholders as part of the Rea Catchment Partnership.
Team Van Oord reviewed the original design and through value engineering put forward amendments which produced savings of £482k, and at the same time improved the scheme’s ‘buildability’.
To help fund the scheme, Calthorpe Estates is proposing to bring the site of the former Pebble Mill Sports and Social Club back into use through development. While the Environment Agency is providing funding towards the works, significant other funding has come through private partner contributions.
Work is currently underway on construction of the culvert under the Pershore Road, which was covered in an ITV Central News report on 15 June.
